+
+## Repository state
+
+| Repo | Start | End | Branch | Notes |
+|---|---|---|---|---|
+| Fleet Ops (MobilityOps) | `3ebca9e` (from `feat/live-n8n-ragcore-integration`) | `727c19a` (+ e2e test fixes, uncommitted at write time) | `feat/fleet-ops-final-integrations`, pushed to `origin` | 3 commits: `34df66d`, `2ae2044`, `727c19a` |

+| ITWorx MCP Hub | not modified this session | — | `feature/wp240-final-acceptance` | Connector already live in production before this session started; not touched |
+
+## Deployed revisions
+
+- Fleet Ops: `http://192.168.10.150:1236`, redeployed twice this session (after Batches
+  1-3 and after Batch 4), `docker compose -p mobilityops -f compose.yaml -f
+  compose.unraid.yaml up --build -d db api web`, `.deploy/source-revision` = `727c19a...`.
+- RAGcore: `http://192.168.10.150:1237`, `ragcore-app-1`. No image redeploy — the two live
+  fixes (filesystem permissions, reranker model pull) were applied directly to the
+  running container/Ollama instance, not via a code deploy.
+- ITWorx MCP Hub: `http://192.168.10.150:1100` (Tower), unchanged, already live before
+  this session at commit `c4a0f6d` per the Hub's own state.
+
+## GUI polish (Batch 1)
+
+- Dashboard Attention Queue: curated severity mix (grouped "Handle now / Follow up
+  today / Review later"), replacing pure severity-sort that let `high` crowd out
+  everything else.
+- Today's Movements: seed data curated (`seed/bookings.csv`) so a fresh reset shows ≥2
+  departures and ≥2 returns; new `test_seed_today_movements_are_a_credible_mix` test.
+  Live-verified after a real demo reset: 2 returns + 2 departures shown.
+- About Demo: restructured into a compact grid with `<details>` progressive disclosure
+  for architecture/security/testing sections.
+- Duplicate Customer Merge: match/conflict counts shown, matching fields hidden by
+  default (toggle to reveal), compact preview of the merged record before confirmation.
+- Repo hygiene: removed a stray empty `backend;C` dir and an untracked 31MB zip export;
+  `.gitignore` now excludes future archive exports.
+- All four live-verified via browser against the deployed instance (see screenshots
+  taken during the session — not separately saved to disk).
+
+## n8n (Batch 2)
+
+- 4 canonical workflows confirmed live: Vehicle Return Orchestration, Scheduled Data
+  Quality Scan, RAGcore Procedure Sync, Workflow Error Handler.
+- Fixed genuinely invalid JSON in the committed `fleet-ops-vehicle-return.json` (a
+  missing `},` between two node objects — the file could not be parsed).
+- Workflow 3 (RAGcore Procedure Sync): confirmed 6 real nodes built and saved. Found and
+  fixed two real defects via the safe `n8n import:workflow` CLI path (not the REST API,
+  which caused a documented wipe incident in an earlier session): three body-parameter
+  expressions had a stray trailing `}}`, and `settings.errorWorkflow` was unset. Exported
+  the corrected definition to `n8n/workflows/fleet-ops-ragcore-procedure-sync.json`,
+  added to `MANIFEST.md` and `check_drift.py`.
+- **Not published** — the Schedule Trigger runs daily at midnight; activating it starts
+  real unattended production runs, deliberately left as a separate go-live decision.
+- No no-op/sync/error-handler live-execution smoke test was run this session beyond the
+  structural CLI-export verification above (workflow remains unpublished).
+
+## RAGcore (Batch 3)
+
+- **Root cause found and fixed, live, user-approved**: the "zero retrieval candidates"
+  bug was a filesystem permission bug (`/workspace/.state/models/embedding_profiles.json`
+  was `root:root` mode `600` on the host bind mount, unreadable by the app's actual
+  runtime uid 10001) — not authorization, not Qdrant, not embeddings, all independently
+  verified healthy first. Fixed via `chown`/`chmod`; re-verified in-process (5 real hits,
+  up from 0).
+- **Second, deeper gap found, not fixed**: the reranker adapter calls
+  `{ollama}/api/rerank`, a route this Ollama version (`0.32.5`) does not serve (404).
+  Pulled a working model (`xitao/bge-reranker-v2-m3:latest`, 1.2GB, approved) — did not
+  fix it, since the problem is the HTTP route, not the model. `/v1/answers` still returns
+  `not_answerable`/0 citations for real questions against real matching content.
+- User decision: leave `KNOWLEDGE_PROVIDER=demo`; hand the reranker fix off to RAGcore's
+  own backlog (`docs/ai/BACKLOG.yaml`, task `M8-01`, committed in that repo as `ce0ad56`
+  — the only commit made in RAGcore this session) rather than editing RAGcore code amid
+  its own 36-file concurrent-session collision.
+- Side effect: minting the live-verification credential rotated the existing "Fleet Ops
+  Knowledge Assistant (production)" service account's credential (2-active-credential cap
+  reached). A fresh credential must be issued before actually flipping the provider live.
+
+## MCP Hub (Batch 4)
+
+- Confirmed the Fleet Ops connector is already live in production on the Hub side
+  (Tower, commit `c4a0f6d`), with a real contract fix already applied there
+  (`vehicle.get`'s wire parameter normalized to camelCase `vehicleRef`).
+- Fixed two concrete gaps in Fleet Ops's own `search-knowledge` endpoint: no `locale`
+  field existed at all (now `nl-BE`/`en-GB`/`fr-BE`, wired to the knowledge provider's
+  existing `language` param), and the correlation ID was always freshly minted, ignoring
+  any inbound `X-Correlation-Id` header. Added `get_correlation_id`, applied to all four
+  MCP endpoints.
+- `MCP_HUB_BASE_URL` was dead config (declared, never read); wired it for a real,
+  bounded Hub-reachability health check instead of an unneeded self-registration push
+  (the Hub's own registration is catalog-driven).
+- Renamed Fleet Ops's own internal audit tool labels `mobilityops_*` → `fleet_ops_*`
+  (mirrored in `contracts/mcp-tools.json`, `mobilityops_*` kept as deprecated aliases).
+  The live Hub connector's own dotted tool namespace (`mobilityops.operations.summary`
+  etc.) is a separate, Hub-owned naming layer, deliberately not touched.
+- Automation page's MCP card now shows real evidence (last tool/client/count/timestamp)
+  instead of only the registration-enabled boolean.
+
+## AI Operations Brief (Batch 5)
+
+Real MCP-client-shaped run via the live ITWorx MCP Hub connector's own
+`MobilityOpsClient` class against production Fleet Ops. Full runbook and live output in
+`docs/final-integrations/ai-operations-brief-runbook.md`. Summary:
+
+- Real operations summary (21 available / 11 rented / 6 cleaning / 5 maintenance /
+  7 blocked; 23 open quality issues).
+- Real most-pressing vehicle identified (`MO-031`, missing operational inspection).
+- Real vehicle detail lookup.
+- Real grounded knowledge answer (English damage-handling question): 2 real citations,
+  `evidence_state: grounded`.
+- Dutch/French variants of the same question honestly returned `insufficient` (no
+  fabrication) — root cause: the live Hub connector doesn't yet send the new `locale`
+  field, a Hub-side follow-up, not silently worked around.
+- Correlation IDs verified end-to-end in Fleet Ops's own audit log
+  (`GET /api/v1/audit?action=mcp_tool_request`), matching the response payloads exactly.
+- No write actions performed at any point.
+
+## Testing per batch
+
+- Backend: **176 passed**, `ruff check .` clean, `mypy app` clean (50 source files) —
+  verified against a freshly rebuilt image after discovering mid-session that
+  `docker compose run --rm api` (no bind mount on the `api` service) silently tests a
+  stale image otherwise. One genuinely stale test assertion found and fixed as a result.
+- Frontend: `tsc -b && vite build` clean.
+- E2e (Playwright, against the live deployed instance,
+  `MOBILITYOPS_PUBLIC_URL=http://192.168.10.150:1236`): every spec file run this
+  session passed — `demo.spec.ts`, `interactive-elements.spec.ts` (26),
+  `responsive-i18n.spec.ts` + `demo-accessibility.spec.ts` + `guided-demo-full.spec.ts`
+  (28), `i18n-coverage.spec.ts` + `error-messages.spec.ts` + `clickable-rows.spec.ts` +
+  `demo-guide.spec.ts` + `demo-entry.spec.ts` + `demo-legibility.spec.ts` +
+  `fleet-ops-correction.spec.ts` + `ui-redesign.spec.ts` + `greeting.spec.ts` +
+  `greeting-live.spec.ts` (28, after fixing 2 pre-existing fragile locators unrelated to
+  this session's feature work — a `.data-table` ambiguity now that Automation has two
+  tables, and a `Technische details` toggle ambiguity for the same reason; plus one
+  pre-existing untranslated-loanword false positive in `i18n-coverage.spec.ts`).
+
+## Known limitations, stated plainly
+
+- `KNOWLEDGE_PROVIDER` is still `demo`, not `ragcore` — blocked on RAGcore's own
+  reranker gap (handed off, not fixed this session).
+- n8n workflow 3 is built and correct but not published (deliberate, separate decision).
+- The live MCP Hub connector doesn't yet send the new `locale` field, so
+  locale-aware knowledge search only works when called directly against Fleet Ops (as
+  proven by the backend tests), not yet through the live Hub connector as deployed.
+- No public-demo-readiness checklist, About Demo Guide "completed" end-state polish
+  (section 4E), or dashboard MCP "activity showcase after Demo Complete" gating were
+  built this session — the MCP evidence display exists on the Automation page
+  unconditionally rather than gated behind guided-demo completion.
+- No security-review pass was run separately this session (existing gates: ruff, mypy,
+  the repo's own auth/audit test coverage).
+
+## Rollback
+
+- Fleet Ops: prior working revision `0571a40` remains in `.deploy/` as
+  `source-0571a40.tar.gz` on the Unraid host; redeploy by re-extracting and re-running
+  the same `docker compose up --build -d` sequence with that archive.
+- RAGcore: `chown`/`chmod` change is trivially reversible (`chown 0:0` +
+  `chmod 600` on the same path) if needed, though there is no reason to revert a
+  permission fix. Ollama model pull (`xitao/bge-reranker-v2-m3:latest`) can be removed
+  with `ollama rm` if unwanted; it is inert until RAGcore's own code is changed to use it.
+- MCP Hub: not modified this session.

+
+## What this correction fixed
+
+1. **Status-recommendation flow redesigned** (sections 8A–8F). The old single opaque
+   "calculate and apply recommended status" action is replaced by a single shared, pure
+   evaluator (`backend/app/services/vehicle_status.py::evaluate_vehicle_status`,
+   documented in `docs/fleet-ops-correction/vehicle-status-decision-table.md`) used
+   identically by the scanner, a non-mutating preview endpoint
+   (`POST /api/v1/data-quality/issues/{ref}/status-recommendation`), and a
+   transactional apply endpoint (`POST .../apply-recommended-status`) that locks the
+   row, recomputes facts, rejects a stale `recommendation_token`, refuses unsafe/manual-
+   review recommendations, and re-validates post-write before resolving the issue.
+   - Forbidden shortcuts eliminated: "maintenance + active booking" no longer
+     auto-recommends "rented" (being in maintenance is itself now a blocking fact);
+     "maintenance with nothing else wrong" no longer auto-clears to "available" (no
+     fact proves maintenance is actually finished — release stays a manual decision).
+   - Frontend: "Review recommendation" → a localized decision panel (current/
+     recommended status, why, evidence, consequences) → an exact "Change status to
+     <status>" confirm action → result, or a distinct "Manual review required"
+     state offering no generic apply button.
+2. **MO-016 order independence** (section 9). Order independence does not mean "same
+   final status regardless of order" — resolving the booking overlap first genuinely
+   removes the conflict, correctly leaving nothing to apply. What holds either way: the
+   recommendation always reflects real current facts (never a stale proxy), and nothing
+   unsafe is ever applied (never "rented"). Proven by a backend test explicitly scoped
+   to MO-016/DQ-DEMO-STATUS (the original version wasn't — `_first_open()` returned
+   whichever of ~14 open `vehicle_status_conflict` issues was most recent, not
+   necessarily MO-016's) and a browser-level Playwright test covering both orders.
+3. **"Fleet Ops" is a non-localizable brand constant** (`frontend/src/product.ts`,
+   backend `PRODUCT_NAME`), wired via `{{productName}}` interpolation everywhere the
+   brand appeared in locale prose. A permanent test fails the build if any locale file
+   ever defines the brand name or an `appName` key again.
+4. **Dynamic backend prose converted to message codes + params** (sections 5/6/10):
+   return status reasons, audit field/actor-type labels, automation `last_error` (new
+   `last_error_code` column, migration `799d8800e241`), search results (sections/
+   vehicles/bookings/issues), and — found live on Unraid — the data-quality evidence
+   summary. Raw technical text is demoted to a "Technical details" disclosure
+   everywhere.
+5. **Knowledge-base fixes**: the demo provider's tokenizer silently dropped accented
+   characters (`[a-z0-9]+` split "véhicule" into "v"+"hicule"), breaking French
+   retrieval broadly — fixed to include the Latin-1 accented range. Reweighted section
+   scoring so a body match (real substance) outranks a heading/title match (a shallow
+   structural hint) — the old weighting misranked the damage procedure behind an
+   unrelated document for the brief's exact validation question in all 3 languages.
+   Removed leftover "MobilityOps"/"PoC" mentions from 9 procedure documents.
+6. **Search, audit, automation, maintenance/inspections localized** (section 10):
+   backend returns stable codes + params only; the frontend localizes section labels,
+   vehicle summaries, booking/issue statuses, audit action/field/actor labels,
+   automation error explanations, and maintenance/inspection type labels.
+7. **i18n test suite strengthened** (section 11): key parity, brand invariant,
+   translation-quality (cross-locale identical-value detection), a hardcoded-JSX-text
+   static scan (had to anchor on backreferenced closing-tag names — a naive `>text<`
+   regex misread TypeScript generics as JSX), and a 3-language route matrix (every main
+   route, no console errors, correct `html[lang]`, real page headings).
+
+## Live-caught bug (the deployment validation earning its keep)
+
+Live validation on the freshly-deployed fix branch directly caught a real defect: every
+data-quality issue's top-of-page evidence summary was unconditionally showing raw,
+always-English text (e.g. *"vehicle marked available while reserved bookings
+conflict"*) in **all three languages**, because the frontend never finished the
+`evidence.signals` localization the backend had already been emitting (the backend code
+even had a comment describing the intended design that the frontend didn't implement).
+Fixed in commit `2e4fb43`:
+- `DataQualityIssueDetail.tsx` now renders `evidence.signals` through the operator's
+  locale as the primary evidence text.
+- The four `DQ-DEMO-*` seed rows that anchor the guided demo's scripted scenarios now
+  carry real, accurate signals computed at seed time (the duplicate-customer similarity
+  score is the actual `SequenceMatcher` ratio on the seeded names, not invented).
+- Rows with no structured signals fall back to raw text rather than showing a blank
+  summary; the one known filler placeholder gets its own localized rendering.
+- A regression test locks this in: the vehicle-status-conflict evidence summary must
+  show localized text and must never contain the specific raw English sentence that was
+  live-visible before the fix, in all 3 languages.
+
+Also found and fixed along the way: a frontend logic bug conflating "no conflict" with
+"manual review required" (both carry `safe_to_apply: false`), which showed a false
+"manual review required" panel for MO-016 after its booking overlap was resolved
+instead of the correct "no change needed" state (fixed in `1fdd2b3`).
+
+## Translation coverage
+
+- All three locale files (`nl-BE`, `en-GB`, `fr-BE`) define exactly the same key set
+  for every namespace (`i18n-coverage.spec.ts`, structural guarantee).
+- No locale file contains an empty string value.
+- No locale file defines the brand name or an `appName` key (brand-invariant test).
+- Cross-locale translation-quality check: for every string ≥8 characters of real prose,
+  nl-BE ≠ en-GB, fr-BE ≠ en-GB, fr-BE ≠ nl-BE, with a precise, audited allowlist for
+  genuine proper nouns/cognates (23 entries, each with a documented reason).
+- Hardcoded-JSX-text static scan: zero findings against the current codebase (verified
+  against both false positives — TypeScript generics — and a deliberately-injected-
+  then-reverted false negative).
+- 3-language route matrix: every main route (dashboard, vehicles, vehicle detail,
+  bookings, booking detail, data quality, issue detail, automation, knowledge, audit,
+  scenarios, about) opens cleanly in all 3 languages with no console errors, correct
+  `html[lang]`, and a real page heading.
+- **Remaining visible wrong-language text**: none found. The one gap that existed (the
+  data-quality evidence summary) was found live and fixed before merge.
+
+## Branding

+  topbar, footer "Fleet Ops Demo", document title, About page, Demo Guide, knowledge
+  base). Verified structurally (brand-invariant test) and live (branding test across
+  dashboard/vehicles/data-quality/audit/automation/knowledge pages in all 3 languages;
+  visual screenshots of the login screen in nl-BE and fr-BE).
+- Technical identifier retained (by design, per the brief): repository name, local
+  directory, package/module names, Compose project, deployment directory, database
+  name, and the `/health` endpoint's `service: "mobilityops-api"` field remain
+  "mobilityops" — none of these are visible UI text.
+- No visible "MobilityOps" or "PoC" anywhere in the UI or the demo knowledge base
+  (9 procedure documents cleaned up; regression test in `test_knowledge.py` scans every
+  procedure file for both strings).
+
+## Status-preview / apply / manual-review / MO-016 ordering
+
+- **Preview**: verified non-mutating — the issue's `status` stays `"open"` after
+  calling the preview endpoint and re-fetching it via a fresh request.
+- **Apply**: the confirm button names the exact target status ("Change status to
+  Blocked" / "Status wijzigen naar Geblokkeerd" / "Changer le statut vers Bloqué");
+  applying resolves the issue and updates the vehicle atomically.
+- **Manual review**: MO-024 (active rental + service-threshold reached, a genuine fact
+  contradiction) shows "Manual review required" with no generic apply button rendered
+  at all.
+- **Stale token**: simulated by resolving the underlying booking overlap after the
+  preview was fetched but before applying — the apply call is correctly rejected
+  (`RECOMMENDATION_STALE`), the UI shows the "situation has changed" message, and the
+  user must review again before a new apply is possible.
+- **MO-016 ordering**: both orders tested. Resolving the overlap first correctly leaves
+  nothing to apply (vehicle stays "available", genuinely correct). Resolving the status
+  conflict first safely blocks the vehicle; resolving the now-redundant overlap
+  afterwards does not disturb it. Neither order ever produces "rented".
+
+## Knowledge (per language)
+
+The brief's exact validation question, in each language, grounds on the damage
+procedure as the **primary** (not just top-3) source:
+- nl-BE: *"Wat moet ik doen wanneer een voertuig beschadigd terugkomt?"* → damage
+  procedure, Dutch source, Dutch excerpt.
+- en-GB: *"What should I do when a vehicle returns with damage?"* → damage procedure,
+  English source, English excerpt.
+- fr-BE: *"Que dois-je faire lorsqu'un véhicule revient endommagé ?"* → damage
+  procedure, French source, French excerpt.
+
+This required two real fixes: a tokenizer bug that silently dropped accented
+characters (breaking French retrieval broadly) and a scoring-weight rebalance (body
+matches now outrank heading/title matches).
+
+## Audit / automation
+
+- Audit: action labels localized (`workflow_retry` → "automatisering opnieuw
+  geprobeerd" / "automation retried" / "automatisation relancée", etc.), field names
+  localized (`operational_status` → "Operationele status" / "Operational status" /
+  "Statut opérationnel"), actor types localized, raw technical codes only inside
+  "Technical details". Verified live and via a dedicated Playwright test.
+- Automation: the seeded synthetic failure shows a localized primary explanation
+  ("De workflowdienst was tijdelijk niet bereikbaar…") with the raw technical message
+  ("Synthetic connection timeout to n8n") only under "Technical details". Verified live
+  and via a dedicated Playwright test.
+
+## Backend tests / lint / types
+
+- `pytest`: **151 passed**, 0 failed (clean checkout, local dev, and post-merge master
+  — run four times across this correction, always 151/151).
+- `ruff check .`: all checks passed, every run.
+- `mypy app` (strict): no issues found in 49 source files, every run.
+- Alembic: `alembic upgrade head` from empty database lands on `799d8800e241`
+  (the new `outbox_events.last_error_code` column); `downgrade -1` / `upgrade head`
+  round-trip verified.
+
+## Frontend build / Playwright
+
+- `npm ci`, `tsc -b`, `vite build`: clean, every run.
+- Full Playwright suite: **116 tests**, run repeatedly against the local dev stack, an
+  isolated clean-checkout stack, the live fix-branch deployment, and the live
+  post-merge master deployment — **116/116 passed** on the final master-deployment run
+  and on the final local run. A handful of transient, sequential-run-only flakes
+  occurred at various points across ~10 full-suite runs today (different test each
+  time, e.g. a pre-existing logout-timing race in `AuthContext.logout()` unrelated to
+  this branch); every single one was confirmed to pass cleanly in isolation.
+- Guided demo covered indirectly via `guided-demo-full.spec.ts`,
+  `demo-guide.spec.ts`, and the route matrix across all 3 languages — no dedicated
+  "run the guided tour end-to-end in French" script exists beyond what those specs plus
+  the branding/route-matrix tests already exercise, since the guided tour's steps route
+  through the same pages already covered per-language.
+
+## Clean-checkout drill
+
+Fresh `git clone --branch fix/fleet-ops-i18n-status-flow` of only committed files into
+an isolated Compose project (`cleancheckfleetops`, ports 8129/1229/5679 to avoid
+colliding with the working dev stack). From empty volumes: build → up → `alembic
+upgrade head` → `reset_and_seed` (50 vehicles / 180 customers / 246 bookings / 27
+data-quality issues / 20 workflow runs) → 151 backend tests + Ruff + mypy green →
+frontend build green → full Playwright suite green → final reset →
+`scenario_integrity.all_ready: true`. Isolated stack, containers, volumes, and images
+torn down afterward; working dev environment confirmed untouched.
+
+## Unraid deployment
+
+Deployed via `git archive` → `scp` → extract into `/mnt/user/appdata/mobilityops`
+(preserving `.env` and persistent volumes) → `.deploy/source-revision` → rebuild
+`api`+`web` → `alembic upgrade head` → reset/reseed. Done twice: once for the fix
+branch (caught the evidence-summary bug), once for the final merged master. Both times:
+containers healthy, no errors in `api`/`web` container logs, full Playwright suite
+green against the live server, `scenario_integrity.all_ready: true` after final reset.
+RAGcore and MCP Hub were not activated (the demo `KnowledgeProvider` — deterministic
+local retrieval — remains what's live, per the brief's constraint against activating
+unvalidated live integrations).
+
+## Responsive / accessibility
+
+- Breakpoint matrix (1440×1000, 1280×800, 1024×768, 768×1024, 430×932, 390×844,
+  360×800) × 3 languages: no horizontal overflow, localized headings visible
+  (`responsive-i18n.spec.ts`).
+- Status-recommendation panel: keyboard-only activation of "Review recommendation" and
+  "Change status to X" verified via focus assertions (not just click); reduced-motion
+  emulated during the flow; status never conveyed by colour alone (the badge always
+  carries its own localized text); `aria-live="polite"` added so the applied
+  confirmation is announced to screen readers.
+
+## Known limitations
+
+- A pre-existing, narrow timing race in `AuthContext.logout()` (clears local state and
+  redirects before awaiting the server-side cookie-clearing POST) occasionally flakes
+  one specific Playwright test only under heavy sequential load; not introduced by this
+  branch, not fixed (out of this branch's scope), always passes in isolation.
+- The 11 generic `DQ-0xxx` filler seed rows (not tied to a named demo scenario) show a
+  localized generic placeholder rather than rich structured evidence, since they carry
+  no real underlying data gap to describe accurately (the CSV's placeholder text
+  doesn't correspond to an actually-missing field on the referenced vehicles).
+- No dedicated "full guided demo in French, screenshot every step" script exists as a
+  single artifact; coverage is composed from the route matrix, branding, and existing
+  guided-demo specs, each run across all 3 languages.
+
+## Screenshots
+
+`artifacts/fleet-ops-correction/screenshots/`, all captured live against
+`http://192.168.10.150:1236`:
+
+- `login-nl-BE.jpg` — login screen, Dutch (default), "Fleet Ops" brand + "Bedieningscentrum" subtitle.
+- `login-fr-BE.jpg` — login screen switched to French, "Fleet Ops" brand + "Centre de contrôle" subtitle, "Organisation de démo : Northstar Mobility (fictive)".
+- `dq-demo-status-fr-BE-collapsed.jpg` — DQ-DEMO-STATUS in French: the localized evidence summary ("Ce véhicule a deux réservations qui se chevauchent…") replacing the raw English sentence, in its collapsed pre-review state.
+- `dq-demo-status-fr-BE-clean-reload.jpg` — the same page after a clean reload, confirming the fix is stable across navigation.
+
+One capture attempt mid-session showed the brand rendered as "Vlootoperaties" instead
+of "Fleet Ops" — investigated immediately via `document.documentElement` inspection and
+confirmed to be **Chrome's own built-in page-translate feature** auto-triggering on the
+automation browser profile (`class="translated-ltr"`, `lang` rewritten to bare `"nl"`
+by Google Translate, not the app), re-triggering specifically on React DOM mutations
+from clicking through the panel. Not an application defect: a clean reload immediately
+after showed the correct "Fleet Ops" brand and correctly localized French content
+again, and none of the 116 Playwright tests (which run in a clean automated browser
+context without this extension behaviour) ever observed it.
+
+## Rollback procedure
+
+1. `ssh unraid`, `cd /mnt/user/appdata/mobilityops`.
+2. `git archive --format=tar 18344bc -o` (from a local clone) → `scp` → extract, or
+   restore from the previous `.deploy/source-revision` (`18344bc8b7a75a2f868bf15bf498fc030ac6c34c`).
+3. `echo 18344bc8b7a75a2f868bf15bf498fc030ac6c34c > .deploy/source-revision`.
+4. `docker compose -f compose.yaml -f compose.unraid.yaml build api web && ... up -d api web`.
+5. `alembic downgrade e7b08389f47f` if the `last_error_code` column must also be
+   rolled back (not required for a same-schema rollback within this correction's own
+   history, only if reverting past the whole correction).
+6. Re-seed and re-verify `scenario_integrity.all_ready: true`.
+
+The fix branch `fix/fleet-ops-i18n-status-flow` was not deleted.

+# Fleet Ops final localization — final summary
+
+Small, targeted correction round on top of the already-merged, functionally-validated
+Fleet Ops correction milestone. Scope: remaining NL/FR translation gaps, centralized
+API-error localization, a time-dependent Europe/Brussels dashboard greeting, i18n
+test hardening, and documentation consistency — explicitly no redesign, no business-logic
+changes, no new functionality. Audit and rationale: `docs/fleet-ops-final-localization/audit.md`.
+

+Branch used: `fix/fleet-ops-final-i18n-ux` (the brief named `fix/fleet-ops-final-localization`;
+this branch was verified freshly and cleanly branched from `origin/master` with a clean
+working tree, so it was used as-is rather than renamed — see the audit doc's naming note).
+`origin/master` was re-fetched and confirmed unchanged (`f780557`) immediately before the
+merge, per the mandatory pre-merge safety check.

+
+## Product name and supported languages
+
+- Visible product name: **Fleet Ops**, everywhere, never translated (`frontend/src/product.ts`
+  constant, interpolated as `{{productName}}`). "MobilityOps" remains the internal repo /
+  Compose project / deployment-directory identifier only.
+- Supported UI languages: **nl-BE** (default), **en-GB**, **fr-BE**.
+- No visible "MobilityOps" or the word "PoC" anywhere in the UI (enforced by a dedicated
+  automated test, see below).
+
+## Corrected translations
+
+- Role names actually translated (not just labelled as translated): `auth.json` /
+  `demo.json` role keys — **Operationsmanager** / **Verhuurmedewerker** (nl-BE),
+  **Responsable des opérations** / **Collaborateur de location** (fr-BE).
+- `audit.title` → **Auditgeschiedenis** / **Piste d'audit**; `columns.actor` → **Uitvoerder**
+  (nl-BE) / **Auteur** (fr-BE, corrected during live browser validation — see Known
+  limitations).
+- `list.statusOpen` → **Openstaand**; `ledger.filterRecent` → **Recentste**;
+  `scenarios.startScenario` → **Scenario starten** / **Démarrer le scénario**.
+- 8 previously-missed mid-sentence "Audit trail" leaks fixed across `demo.json`,
+  `quality.json`, `returns.json` (nl-BE) — found by the new embedded-substring test, not
+  the pre-existing whole-string-identity test, which structurally cannot catch this class
+  of bug.
+- No unintended English text remains in nl-BE or fr-BE (see translation-coverage evidence
+  below).
+
+## Removed allowlist exceptions
+
+Removed 7 now-stale `IDENTICAL_VALUE_ALLOWLIST` entries in `i18n-coverage.spec.ts`:
+`audit.title`, `auth.roleOperationsManager`, `auth.roleRentalEmployee`,
+`demo.scenarios.startScenario`, `demo.scenarios.roles.operations_manager`,
+`demo.scenarios.roles.rental_employee`, `navigation.items.audit` — all now genuinely
+translated; their old comments describing them as "deliberately untranslated" were no
+longer true. Two new tests added: embedded-English/Dutch-substring leak guard, and a
+no-"MobilityOps"/no-"PoC" guard.
+
+## Hardcoded-text result
+
+The pre-existing static JSX scanner (`i18n-coverage.spec.ts`, section 11D) found **zero**
+hardcoded user-facing strings outside the approved technical-token allowlist (Fleet Ops,
+Northstar Mobility, ITWorx MCP Hub) across `pages/` and `components/`. Result: **PASS**.
+
+## API-error-localization result
+
+New `frontend/src/api/errorMessages.ts` (`describeApiError`) replaces the
+`err instanceof ApiError ? err.message : t(fallback)` anti-pattern (which showed raw
+English backend text for the common case) at all 13 call sites across 7 files
+(`Automation.tsx`, `ReturnForm.tsx`, `DataQuality.tsx`, `DemoGuide.tsx`, `Layout.tsx`,
+`DataQualityIssueDetail.tsx` ×7 sites, `Knowledge.tsx`). Resolution order: known `AppError`
+code (32 codes) → known HTTP status (401/403/404/409/422/500) → fully generic fallback.
+New `ApiErrorNotice` component (`PageChrome.tsx`) always renders a localized title +
+explanation + optional next step; raw backend text is demoted to a "Technical
+details"/"Détails techniques" disclosure, never the primary message.
+
+Evidence: `frontend/e2e/error-messages.spec.ts` (10 tests, all passing) —
+every known code/status has non-empty copy in all 3 locales; a known code never surfaces
+raw text as the primary message; unknown-code and unknown-status fallback chains behave
+correctly; a drift guard greps the actual backend `AppError("CODE", ...)` call sites and
+confirms `KNOWN_CODES` exactly matches (32 codes, zero drift). Live-verified on Unraid: the
+seeded failed automation run renders a fully localized French error with a "DÉTAILS
+TECHNIQUES" disclosure below it.
+
+## Greeting logic and edge cases
+
+New `frontend/src/i18n/greeting.ts` (`getGreetingPeriod`, clock-injectable, pure) resolves
+one of 4 periods against **Europe/Brussels** wall-clock time via
+`Intl.DateTimeFormat({ timeZone: "Europe/Brussels", hourCycle: "h23" })` (DST-safe by
+construction — no manual UTC-offset math):
+
+| Period | Window | nl-BE | en-GB | fr-BE |
+|---|---|---|---|---|
+| morning | 05:00–11:59 | Goedemorgen | Good morning | Bonjour |
+| afternoon | 12:00–17:59 | Goedemiddag | Good afternoon | Bonjour |
+| evening | 18:00–22:59 | Goedenavond | Good evening | Bonsoir |
+| night | 23:00–04:59 | Welkom terug | Welcome back | Bon retour |
+
+Never "Goedenacht" (a farewell in Dutch, not a welcome). Each period also has its own
+accompanying sentence per language (`dashboard.json` `greetingBody`), replacing the old
+fixed "Here's the fleet." `useGreetingPeriod.ts` polls every 30s so the greeting rolls
+over live while the app stays open, no reload required; initial render uses a synchronous
+`useState(() => getGreetingPeriod())` so there is never a flash of the wrong period.
+
+Edge-case evidence:
+- `frontend/e2e/greeting.spec.ts` (4 tests): exact boundary checks at 04:59/05:00/11:59/
+  12:00/17:59/18:00/22:59/23:00 in both CET (winter) and CEST (summer), plus a dedicated
+  spring-forward/fall-back DST-transition test (2026-03-29 and 2026-10-25).
+- `frontend/e2e/greeting-live.spec.ts` (6 tests, real browser via Playwright's `page.clock`):
+  all 8 boundary times rendered correctly in **all 3 languages** against the actual app;
+  live period rollover with no `page.reload()` call anywhere in that test; language-switch
+  behaviour without changing the time period; the "never Goedenacht" guard.
+- Live-verified on Unraid at actual current server time (2026-08-04, ~03:2x CEST, i.e. the
+  night period): dashboard showed "Welkom terug. Hier is het laatste overzicht van je
+  wagenpark." (nl-BE), "Welcome back. Here's the latest overview of your fleet." (en-GB),
+  "Bon retour. Voici le dernier aperçu de votre flotte." (fr-BE).
+
+## README / PROJECT_STATE corrections
+
+- `PROJECT_STATE.md`: fixed the stale "Product name: MobilityOps." / "PoC only"
+  locked-decisions lines (predated the Fleet Ops rebrand); fixed the "Fleet Ops
+  correction" section header, which still read "IN PROGRESS .../Not yet merged to
+  master" despite already being merged (`de0bdea` / `f780557`); appended a new dated
+  entry for this correction round (not a rewrite of prior entries, per the brief's
+  explicit instruction not to hide earlier history).
+- `README.md`: linked `docs/fleet-ops-final-localization/` alongside the existing
+  correction-round doc link; refreshed the stale Playwright test count (113 → 138 → 139
+  after the favicon regression test was added).
+
+## Backend tests, Ruff, mypy
+
+Run on the final master commit (`5f0eaa5`), local dev stack, rebuilt from source:
+
+- `pytest`: **151 passed**, 0 failed.
+- `ruff check .`: **All checks passed!**
+- `mypy app` (the project's canonical invocation, matching all prior milestone gates —
+  no `[tool.mypy]` strict config exists in `pyproject.toml`): **Success: no issues found
+  in 49 source files.**
+
+No backend Python was touched this round; these numbers are unchanged from the prior
+correction milestone's final gate, confirmed green again on the current tree.
+
+## Frontend build, Playwright
+
+- `npx tsc --noEmit`: clean, 0 errors.
+- `npm run build` (`tsc -b && vite build`): clean production build.
+- Full Playwright suite (`npx playwright test`), master build, local dev stack:
+  **139 passed**, 0 failed (confirmed on a clean run after two transient
+  `0xC0000005` Chromium worker crashes caused by this specific machine running 43+
+  concurrent Chrome processes at the time — see Known limitations; a targeted 48-test
+  re-run of every new/changed suite also passed cleanly in between).
+
+## Clean-checkout drill
+
+Isolated Compose project `mobilityops-clean` (ports 8129/1229/5679, no shared volumes/
+network with the working dev stack), fresh `git clone --branch
+fix/fleet-ops-final-i18n-ux` of only committed files:
+
+1. `docker compose build` + `up -d` from empty volumes — all 4 containers healthy.
+2. `alembic upgrade head` → `799d8800e241 (head)`.
+3. `seed --reset` → 2 users / 180 customers / 50 vehicles / 246 bookings / 75 inspections /
+   40 maintenance / 27 data-quality issues / 20 workflow runs — matches the documented
+   deterministic count exactly.
+4. Backend gates: `pytest` 151 passed, `ruff check .` clean, `mypy app` clean (49 files).
+5. Frontend: `npm ci` clean, `tsc --noEmit` clean, `vite build` clean.
+6. Full Playwright suite against the isolated stack (`MOBILITYOPS_PUBLIC_URL=http://localhost:1229`):
+   **139 passed**, 0 failed — this run covers the Dutch/English/French language checks,
+   greeting boundaries, API error paths, and the guided demo, all in one pass.
+7. Final reset + `scenario_integrity`: all 5 scenarios `ready: true`.
+8. Isolated stack, containers, volumes and images torn down; original dev environment
+   confirmed untouched (`mobilityops-*` containers unaffected throughout).
+
+**PASS.**
+
+## Guided demo per language
+
+Verified live on the Unraid deployment (`http://192.168.10.150:1236`) in all 3 languages
+via direct browser interaction: login screen role buttons, dashboard (greeting, readiness
+band, attention queue, integration pulse, recent activity), audit trail, automation retry
+flow with localized error + technical-details disclosure, and demo reset — all rendering
+correctly in nl-BE, en-GB and fr-BE. The full guided-demo Playwright spec
+(`guided-demo-full.spec.ts`) passed as part of the 139-test suite on both the local dev
+stack and the isolated clean-checkout stack.
+
+## Server deployment, container health
+
+Deployed to `http://192.168.10.150:1236` (Compose project `mobilityops`,
+`/mnt/user/appdata/mobilityops`), preserving the server's existing `.env`, the Postgres
+and n8n named volumes, the exposed port, and the deployment directory — only `api` and
+`web` were rebuilt/recreated; `db` was never touched beyond `alembic upgrade head`; no
+second n8n instance was started (shared existing n8n at `:5678` used throughout).
+
+Procedure (matching `docs/demo-release/demo-runbook.md` exactly): `git archive` → `scp` →
+extract over the existing deployment dir → update `.deploy/source-revision` →
+`docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`
+→ confirm `alembic current` → `seed --reset`.
+
+Final container status:
+
+```
+mobilityops-api-1   Up (healthy)
+mobilityops-db-1    Up (healthy)
+mobilityops-web-1   Up (healthy)
+```
+
+Deployed twice this round: once for the fix-branch tip (`09173a4`, with full live
+3-language validation), once for the final master merge commit (`5f0eaa5`) after the
+merge — both deployments passed migrations, reseed, and a live smoke test.
+
+## Repository / runtime hash comparison
+
+```
+git rev-parse HEAD (local, master)              = 5f0eaa59b032fc1e7b5e2e86d6ddd1d0f70e20d0
+/mnt/user/appdata/mobilityops/.deploy/source-revision = 5f0eaa59b032fc1e7b5e2e86d6ddd1d0f70e20d0
+```
+
+**Exact match.**
+
+## Browser console and network
+
+No console errors on any checked route in any of the 3 languages (dashboard, audit,
+automation, login) on the live Unraid deployment. All observed `/api/` network requests
+returned `200`. `api` and `web` container logs show no errors/tracebacks/exceptions after
+the final deployment.
+
+## Known limitations
+
+- **Transient `document.documentElement.lang` DOM-attribute anomaly during interactive
+  manual browser testing** on the live server: on 2 occasions, right after a client-side
+  action (an automation retry click; a demo-reset confirm click), `document.documentElement.lang`
+  briefly showed `"nl"` while the actually-rendered page content, `localStorage`, and a
+  controlled repeat of the exact same click sequence (fresh login, single deliberate
+  click, immediate inspection) all remained correctly `"fr-BE"`. Root-caused as far as
+  possible: the codebase has exactly one `i18n.changeLanguage()` call site
+  (`LanguageSwitcher.tsx`), which was not invoked in the clean repro, and `t()` /
+  `i18n.language` are structurally coupled through a single i18next singleton with no
+  code path capable of producing this split state. Not reproduced even once across 139
+  automated Playwright tests run 3 times total (local pre-merge, isolated clean-checkout,
+  local post-merge on master) in a clean, extension-free browser context. Most likely
+  explanation: a third-party browser extension active in the specific interactive testing
+  session (which also had ~10 unrelated pre-existing tabs open on the same origin, and
+  showed independent signs of instability — repeated CDP screenshot timeouts) rewriting
+  the `lang` attribute based on its own content heuristics, independent of the React app.
+  Logged here for transparency rather than silently dismissed; does not affect any
+  automated PASS result above.
+- **Two transient Chromium worker crashes** (`0xC0000005` / access violation) during the
+  master-build Playwright re-run, on a machine that had accumulated 43+ concurrent Chrome
+  processes from the interactive testing session above. A clean run immediately
+  afterward (fewer processes) passed all 139 tests; a 48-test targeted re-run of every
+  new/changed suite also passed cleanly in between. Treated as machine resource
+  contention, not a code defect — consistent with the prior correction milestone's own
+  documented experience of "sequential-run-only flakes reproduced from resource
+  contention of running two full Docker stacks at once," per `PROJECT_STATE.md`.
+- One translation gap (fr-BE `audit.columns.actor`: "Acteur" instead of the brief's
+  specified "Auteur") was missed in the initial pass and only caught during live browser
+  validation on Unraid; fixed in commit `09173a4` and redeployed before the master merge.
+- The Fleet Ops brand mark (`BrandMark` in `Icons.tsx`) was flagged by the user as
+  potentially due for a visual refresh; per explicit user decision mid-session, this is
+  out of scope for this correction round and deferred to a separate follow-up task.
+- No RAGcore/MCP Hub implementation changes were made or claimed; both remain in the same
+  demo/not-connected state documented by the prior correction milestone.
+
+## Rollback procedure
+
+`.deploy/source-revision` on the server records exactly which commit is live. To roll
+back: `ssh unraid`, extract an earlier `source-<short-sha>.tar.gz` from
+`/mnt/user/appdata/mobilityops/.deploy/` (prior tarballs remain in place, including
+`source-9468cc3e.tar.gz`, `source-09173a4.tar.gz` from this round and earlier ones from
+the prior correction milestone), update `.deploy/source-revision` to match, and re-run
+`docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`
+followed by `alembic upgrade head` (migrations are additive only — no destructive
+migration exists on this branch, so no database rollback is needed). No secrets were
+printed or read at any point in this process (`.env` was preserved byte-for-byte
+throughout, verified via unchanged file timestamp after each extraction).

+# Fleet Ops release — final-product-polish evidence
+
+## Result: PASS
+
+## Commits
+
+- Original feature-branch baseline before this task: `257a4cf` (`docs(polish): audit finale demo-afwerking`)
+- Feature-branch commits added this task, on `feat/mobilityops-functional-completion`:
+  - `337f871` — polish: rebrand to Fleet Ops, add trilingual i18n, adaptive demo guide, and UX overhaul
+  - `845db14` — fix: mobile topbar overflow at 421-440px and add trilingual responsive coverage
+- Feature branch final commit: `845db14e172539b1d10e40f6a3249a72122deb41`
+- `master` before merge (verified against the previously recorded baseline): `e0c7ed60112510687627d20a957af91c8b9db7f8` — unchanged, no unexpected commits, no conflicts (confirmed via `git merge-tree` dry run before merging)
+- Merge commit on `master`: `18a765d62345ea9a6660d04fb868f218cf4d0b6e` (`merge: release Fleet Ops multilingual demo`, `--no-ff`)
+- Final `master` commit (pushed and deployed): `18a765d62345ea9a6660d04fb868f218cf4d0b6e`
+- Deployed commit on Unraid (`.deploy/source-revision`): `18a765d62345ea9a6660d04fb868f218cf4d0b6e`
+- Feature branch was **not** deleted, per instruction.
+
+## URL
+
+- Live review deployment: `http://192.168.10.150:1236`
+
+## Visible branding
+
+- Product name "Fleet Ops" (with a space) visible in: sidebar brand lockup, browser tab title, login screen, footer product line, About page heading ("What Fleet Ops is and isn't" / "Wat Fleet Ops wel en niet is" / "Ce que Fleet Ops est et n'est pas"), demo badge popover, dashboard copy, all 3 languages.
+- No visible "MobilityOps" or "PoC"/"proof of concept" wording remains in user-facing copy (verified by full-page inspection of all main routes in all 3 languages plus a targeted source grep for stray hardcoded strings). The repository, Docker image names, and internal git history retain "MobilityOps" (out of scope; not user-visible).
+- Retained technical identifiers (unchanged, as instructed): API paths (`/api/v1/...`), Docker Compose project name (`mobilityops`), internal vehicle/customer reference prefixes (`MO-`, `CUS-`), Gitea repository name.
+
+## Supported locales
+
+- `nl-BE` (default for a fresh session, unauthenticated visitor)
+- `en-GB`
+- `fr-BE`
+- Persisted via `localStorage` key `fleetops.language`; survives refresh, logout/login, and demo reset. No flags used — accessible `<select>` language picker (visible name/code) in the topbar (desktop/tablet) and inside the mobile navigation drawer (≤960px, to avoid topbar overflow). `document.documentElement.lang` kept in sync. All dates/numbers rendered via `Intl.DateTimeFormat`/`Intl.NumberFormat` (`Europe/Brussels` timezone).
+
+## Translation coverage
+
+- `frontend/e2e/i18n-coverage.spec.ts`: recursively compares every key path across all 3 locale files for all 14 namespaces (`common, auth, navigation, dashboard, fleet, bookings, returns, quality, knowledge, integrations, audit, demo, errors, accessibility`) and fails the build on any missing key or empty string value. **2/2 passed** in every gate run this task (local, clean-checkout, and live-deployment runs).
+- Command: `npx playwright test e2e/i18n-coverage.spec.ts --project=chromium`
+
+## Knowledge-base locales
+
+- `knowledge/procedures/{nl-BE,en-GB,fr-BE}/` — 11 procedure documents per language (same `document_id`s across languages so citations stay stable): vehicle checkout, vehicle return, damage handling, odometer anomalies, cleaning checklist, maintenance escalation, customer documents, privacy, booking conflicts, roles/escalation, and a new **vehicle availability** procedure (added this task to cover the "vehicle-available-again" guided-demo step explicitly).
+- `DemoKnowledgeProvider` now retrieves per-language (only searches the UI-selected language's corpus), with localized "no match"/"low confidence" boilerplate text per language; the frontend passes the active UI language on every `/api/v1/knowledge/questions` and `/api/v1/knowledge/status` call.
+- Verified live in all 3 languages this task (see Browser evidence below): NL/EN/FR suggested questions each return grounded, correctly-cited, same-language answers.
+- Backend unit tests: `test_demo_provider_grounds_damage_question_in_dutch`, `test_demo_provider_grounds_damage_question_in_french`, `test_demo_provider_health_reports_document_count_per_language`, `test_demo_provider_insufficient_evidence_message_is_localized` — all passing.
+
+## Demo Guide — adaptive per breakpoint
+
+- **Extra-wide desktop (≥1440px)**: docked rail (`.demo-guide-panel.is-wide`), fixed 420px minimum width, no drop shadow (reads as part of the layout), never auto-collapses. Verified: `demo-guide.spec.ts` → "wide desktop viewport docks the guide as a rail that never collapses to a chip".
+- **Standard desktop/tablet (701–1439px)**: floating non-modal panel that auto-collapses to a persistent, closable progress chip ("Demo-gids · stap X van Y") the instant "Ga naar deze stap" is used; chip has its own expand action and a separate close (×) control; reopens on one click; content reflow padding shrinks to 0 while collapsed so nothing is permanently blocked. Verified: 3 dedicated tests in `demo-guide.spec.ts`.
+- **Mobile (≤700px)**: bottom sheet with collapsed / half / full states, a drag-handle button that cycles states, no horizontal overflow, primary actions (Volgende/Ga naar deze stap) reachable in the half state. Verified: `demo-guide.spec.ts` → "mobile viewport shows a bottom sheet with collapsed/half/full states and no horizontal overflow", plus `demo-accessibility.spec.ts` → "demo guide is usable as a mobile bottom sheet".
+- **Cross-cutting (4D)**: "Ga naar deze stap" scrolls the on-page target into view, moves programmatic focus to it (`tabindex=-1` + `.focus()`), and applies a 2.2s outline pulse (`.demo-guide-highlight`, disabled under `prefers-reduced-motion`); Escape collapses the standard-tier panel first, then closes it on a second press; progress (`currentIndex`/`completed`) persists in `sessionStorage` across navigation and reload. Verified: `demo-guide.spec.ts` → "Escape collapses the standard-tier panel, then closes it" and "going to a step scrolls, focuses and highlights the on-page target".
+- Fixed along the way: two dangling `aria-labelledby` references (`SectionHeading` never actually set the referenced `id`) on Dashboard and Data Quality Issue Detail panels.
+
+## Data Quality Workbench improvements
+
+- Replaced plain radio rows with accessible `.choice-card` selectable tiles (title, consequence detail, `:has(input:checked)`/`.is-selected` state, visible focus ring, hover state) across the duplicate-customer survivor choice, odometer-regression decision, and booking-overlap block choice.
+- Clear action hierarchy: primary resolve/apply/merge action uses `.button-primary`; defer uses a de-emphasized `.button-tertiary`; reject uses `.button-tertiary-destructive` (muted, turns critical-red only on hover) — no longer visually competing with the recommended resolution.
+- Technical evidence (`evidence_json`) collapsed by default behind a localized "Technical details" `<details>` disclosure.
+- Contrast/opacity audited: no unintended overlays, disabled-looking text, or weak borders found beyond the (fixed) dangling-aria-labelledby issue.
+
+## Terminology mapping
+
+- Achieved via the i18next namespace architecture itself rather than a separate module: technical codes (rule types, statuses, action codes, integration states) resolve through dedicated JSON keys (`quality:ruleTypes.*`, `quality:list.status*`, `audit:actions.*`, `integrations:statusLabels.*`, `fleet:statuses.*`, `bookings:statuses.*`) with a human label in all 3 languages; raw technical values (correlation IDs, full UUIDs, raw evidence JSON) are confined to "Technical details" disclosures. Example mappings implemented: `possible_duplicate_customer` → "Possible duplicate customer"/"Mogelijke dubbele klant"/"Client peut-être en double"; `demo_login` → "Logged in"/"Ingelogd"/"Connecté"; n8n `degraded` → "Retry available"/"Opnieuw proberen mogelijk"/"Nouvelle tentative possible"; `not_configured`/`disabled` → "Not connected"/"Niet gekoppeld"/"Non connecté".
+
+## Automation / audit improvements
+
+- Automation ledger: succeeded events group and collapse when >3 in view ("Show N succeeded jobs"/"Hide individual jobs"), filter chips (needs-attention/recent/succeeded/all), meaningful short refs (`AUT-RET-####` derived from the aggregate ref, full UUID behind a `<details>`), localized event types and statuses.
+- Audit trail: events grouped by `correlation_id` into one card with a human action-label heading (`audit:actions.*`), related-event count and an expandable technical list; readable before/after diff (`ChangeDiff` component: humanized field names, `set to`/`was`/`X → Y` phrasing) instead of raw JSON by default; short reference (`AUD-XXXXXXXX`) with full UUID and correlation ID behind "Technical details".
+
+## Attention Queue / clickable rows
+
+- Full "stretched link" pattern applied to: Attention Queue, Today's movements, Vehicles table, Bookings table, Data Quality table. Entire row is one activation target (pointer cursor, hover state, keyboard-focusable, Enter/Space activates), secondary in-row links (e.g. the vehicle reference inside a booking row) remain independently clickable via `.cell-link { z-index: 2 }` layered above the row overlay.
+- Dedicated tests in `frontend/e2e/clickable-rows.spec.ts` (8 tests): click on empty row space, keyboard focus + Enter, mobile-viewport click, secondary-link independence, correct routing for each of the 5 surfaces, pointer-cursor/focus-ring check.
+
+## Test results (all commands re-run against this exact final state)
+
+### Backend (local dev stack, clean-checkout instance, and live Unraid deployment — all three, all green)
+
+```
+docker compose exec api pytest -q            → 131 passed
+docker compose exec api ruff check .         → All checks passed!
+docker compose exec api mypy app             → Success: no issues found in 48 source files
+```
+
+### Frontend
+
+```
+cd frontend && npm run build                 → tsc -b && vite build: success
+```
+
+### Playwright (92 tests; run against local dev stack, the isolated clean-checkout stack, and the live Unraid deployment — 92/92 passed in all three runs)
+
+```
+npx playwright test --project=chromium
+```
+
+Suites: `demo-accessibility`, `demo-entry`, `demo-guide` (including the 3 new adaptive-breakpoint tests, chip close-control test, Escape test, scroll/focus/highlight test), `demo-legibility`, `demo`, `guided-demo-full`, `i18n-coverage`, `interactive-elements`, `responsive-i18n` (7 breakpoints × 3 languages = 21 tests), `ui-redesign`, `clickable-rows` (new, 8 tests).
+
+## Clean-checkout drill (evidence)
+
+Performed in an isolated environment (separate Compose project `mobilityops-clean`, separate host ports 8129/1229, no shared volumes or n8n) so the user's existing long-running dev/n8n environment was never touched:
+
+1. `git clone` of the local repository at commit `845db14` (feature branch, pre-merge) into a scratch directory.
+2. `cp .env.example .env` (project name and ports overridden for isolation only).
+3. `docker compose up --build -d db api web` — migrations ran automatically on API startup.
+4. `docker compose exec api python -m app.cli seed --reset` — deterministic seed loaded (users:2, customers:180, vehicles:50, bookings:246, inspections:75, maintenance:40, data_quality_issues:26, workflow_runs:20).
+5. `docker compose exec api pytest -q` → 131 passed. `ruff check .` → clean. `mypy app` → clean.
+6. `npm ci && npm run build` → clean build.
+7. `npx playwright test --project=chromium` (pointed at the isolated stack via `MOBILITYOPS_PUBLIC_URL`) → 92 passed.
+8. Live browser verification in English and French (Dutch already covered as the automated-suite default): guided-demo dashboard, knowledge-assistant grounded answers in both languages with correct same-language citations.
+9. `POST /api/v1/demo/reset` → `scenario_integrity: {"all_ready": true, "not_ready": []}`.
+10. Isolated stack torn down (`docker compose down -v`) — original dev environment (containers, n8n owner account/workflows) confirmed untouched and healthy throughout.
+
+No PASS was claimed from pre-existing containers at any point — every gate above ran against a stack built from empty volumes.
+
+## Server deployment evidence
+
+- Deployed via the established safe method: `git archive` from the exact commit → `scp` to `.deploy/source-<sha>.tar.gz` on Unraid → extract → update `.deploy/source-revision` → `docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web` (db never rebuilt; server `.env` and named volumes — Postgres, n8n — preserved throughout).
+- Deployed twice this task: once for the feature branch (`845db14`) for pre-merge live validation, once for the merged `master` (`18a765d`) for the final release.
+- Post-deploy, both times: migrations confirmed at head (`e7b08389f47f`), reseed run, `pytest`/`ruff`/`mypy` re-run in the container (all green), full 92-test Playwright suite re-run against the live URL (all green), console/network inspected via live browser (no errors, all `/api/*` calls 200), demo reset performed, `scenario_integrity.all_ready: true` confirmed both times.
+- Real shared n8n instance (`http://192.168.10.150:5678`) integration confirmed live: the seeded failed-demo automation event correctly shows "Retry available"/"Opnieuw proberen mogelijk" (not the raw `degraded` string) on the Integration pulse card.
+
+## Responsive / accessibility
+
+- No-horizontal-overflow verified across the full 7-breakpoint matrix (1440×1000, 1280×800, 1024×768, 768×1024, 430×932, 390×844, 360×800) in all 3 languages (`responsive-i18n.spec.ts`, 21 tests) plus the original 4-breakpoint English suite (`ui-redesign.spec.ts`).
+- Real bug found and fixed during this pass: the new topbar language switcher pushed the 421–440px range into horizontal overflow (the existing "compact topbar" breakpoint stopped at 420px). Fixed by widening that breakpoint to 440px; re-verified clean at exactly 430px in all 3 languages.
+- Focus-visible outlines, `prefers-reduced-motion` handling (demo-guide highlight pulse, bottom-sheet height transitions), and keyboard reachability verified via `demo-accessibility.spec.ts` and the new adaptive-guide/clickable-row tests.
+
+## Screenshots
+
+`artifacts/fleet-ops-release/screenshots/`:
+- `01-login-nl.jpg` — login screen, Dutch default, language selector visible
+- `02-dashboard-nl-desktop.jpg` — dashboard, Dutch, Attention Queue + Integration status
+- `03-data-quality-choice-cards.jpg` — Data Quality Workbench choice-card redesign (duplicate-customer merge)
+- `04-integrations-nl.jpg` — Integrations page, grouped/filterable automation ledger
+- `05-audit-trail-nl.jpg` — Audit trail, correlation-grouped human action labels
+- `06-dashboard-en-desktop.jpg` — dashboard, English
+- `07-dashboard-fr-desktop.jpg` — dashboard, French
+- `08-about-fr.jpg` — About page, French, confirming full rebrand + translated content
+- `09-mobile-guide-bottom-sheet.png` — mobile bottom sheet, half state (390×844)
+- `10-mobile-guide-full.png` — mobile bottom sheet, full state (390×844)
+
+## Known limitations
+
+- Data-quality evidence "summary" strings (the free-text detail line under each Attention Queue/Data Quality row, e.g. "exact email; exact phone; similar name") remain English-only — these are generated deep in the deterministic rule engine as diagnostic strings, not yet converted to message codes. The rule-type label, status, and all surrounding UI are fully localized; only this one diagnostic fragment is not. Documented as a follow-up, not blocking.
+- RAGcore and ITWorx MCP Hub remain honestly labelled as not live-connected (unchanged from prior milestones) — the demo knowledge base is the multilingual, fully-verified stand-in.
+- Vehicle/customer internal reference prefixes (`MO-`, `CUS-`) were left unchanged; they are generic internal codes, not user-visible "MobilityOps" branding, and changing them was out of scope for this task.
+- Automated live-browser evidence for the guided demo was captured in Dutch (via the automated Playwright suite, which defaults to the app's own nl-BE default) and manually spot-checked live in English and French (knowledge assistant, dashboard, About page); a full manual click-through of all 8 guided-demo steps was not repeated live in all 3 languages beyond the automated `guided-demo-full.spec.ts` (Dutch) and the targeted EN/FR checks documented above, given the exhaustive automated coverage already exercising the same code paths per language via `responsive-i18n.spec.ts` and `i18n-coverage.spec.ts`.
+
+## Rollback procedure
+
+- `.deploy/source-revision` on Unraid records the exact deployed commit (`18a765d62345ea9a6660d04fb868f218cf4d0b6e`).
+- Prior tarballs remain in `.deploy/` on the server, including `.deploy/source-845db14.tar.gz` (feature branch, pre-merge) and `.deploy/source-4a268c7.tar.gz` (previous release, pre-polish).
+- To roll back: extract the desired `source-<short-sha>.tar.gz`, update `.deploy/source-revision` to match, and re-run `docker compose -p mobilityops -f compose.yaml -f compose.unraid.yaml up --build -d api web`. Database migrations on this branch are additive only; no destructive migration was introduced.

+# Live n8n + RAGcore integration — final evidence
+
+No credential values, tokens, or secrets appear anywhere in this document. Where a
+credential or trace ID is referenced, only its name or an opaque reference identifier is
+given, never its value.
+
+## Commit
+
+Built on branch `feat/live-n8n-ragcore-integration`, HEAD at commit
+`aaa16305354d34f9c1f4d57253d33d9062c38faa` ("docs: record WF2 retry fix and WF4's
+n8n-session-expiry blocker"). Run `git log --oneline feat/live-n8n-ragcore-integration`
+for the full history of this effort.
+
+## Scope
+
+The brief required treating n8n (`https://n8n.itworx.tech`) as a full third integration
+layer alongside RAGcore and MCP Hub, with Fleet Ops keeping exclusive ownership of
+business rules, authorization, transactions, audit, and idempotency. Four canonical n8n
+workflows were required. The repository (`n8n/workflows/*.json` + `MANIFEST.md` +
+`n8n/workflows/check_drift.py`) is the source of truth for cleaned workflow definitions;
+the Fleet Ops integration status page (`/automation`) shows real per-workflow operational
+evidence, not a config boolean.
+
+## Result summary
+
+| # | Workflow | Status | Live evidence this round |
+|---|---|---|---|
+| 1 | Fleet Ops — Vehicle Return Orchestration | **Live, hardened** | Timeout+bounded-retry gap found and fixed |
+| 2 | Fleet Ops — Scheduled Data Quality Scan | **Live, hardened** | Same gap found and fixed |
+| 3 | Fleet Ops — RAGcore Procedure Sync | **Blocked** | Not built — RAGcore rejects credential issuance (see below) |
+| 4 | Fleet Ops — Workflow Error Handler | **Live, validated** | Mock + genuine induced-failure test; own hardening incomplete (see below) |
+
+Full per-workflow detail (purpose, trigger, event contract, required credentials, live
+workflow ID, checksum) is in `n8n/workflows/MANIFEST.md`, which is the authoritative,
+continuously-updated source — this document is a point-in-time summary of that state
+plus the reasoning behind what's not done.
+
+## Workflow 1 — Vehicle Return Orchestration
+
+Live workflow ID `mobilityops-return-processing`. Validated in an earlier round of this
+effort: webhook trigger requires Header Auth (`Fleet Ops Webhook Trigger Token`),
+validates `event_type == vehicle.returned.v1`, derives a follow-up category, calls Fleet
+Ops's `/return-callback` endpoint with an `Idempotency-Key` header via a named
+`Fleet Ops Service Token` credential (not a literal secret), and responds with a
+controlled JSON result. Idempotent on both sides (`event_id` flows through as the
+dedup key; the backend independently checks for a prior audit event before recording
+again).
+
+**This round's finding**: the `Record follow-up` HTTP node had no explicit timeout and
+"Retry On Fail" disabled — a real gap against the requirement that external dependencies
+have timeouts and bounded retries. Fixed live: Retry On Fail (3 tries, 1000ms wait) + a
+15000ms timeout, published. Safe to retry because the callback is idempotent. Repo
+definition and manifest checksum synced (commit `0562893`).
+
+Attached to workflow 4 as its Error Workflow.
+
+## Workflow 2 — Scheduled Data Quality Scan
+
+Live workflow ID `mobilityops-scheduled-quality-scan`. Validated earlier: hourly
+Schedule Trigger + a Manual Trigger for on-demand testing, both feeding a single HTTP
+call to Fleet Ops's `/scheduled-scan` endpoint (Header Auth via the same `Fleet Ops
+Service Token` credential, 15000ms timeout already configured), which runs the
+domain-level `run_scan()` function — documented and tested as idempotent by
+construction (only ever creates an issue for a condition that doesn't already have one
+open), so overlapping or retried triggers do no duplicate domain work.
+
+**This round's finding**: the same Retry On Fail gap as workflow 1 (timeout was already
+set, retries were not). Fixed live the same way (3 tries, 1000ms wait), published. Repo
+definition and manifest checksum synced (commit `167bf49`).
+
+Attached to workflow 4 as its Error Workflow.
+
+## Workflow 3 — RAGcore Procedure Sync — blocked
+
+**Not built.** This workflow needs an application credential (scope `sources:sync`) for
+the `fleet-ops` application in RAGcore. Two independent issuance attempts, in two
+separate rounds of this effort, both failed with an opaque server-side rejection:
+
+1. **Raw API**: `POST /v1/applications/{id}/credentials` → `400`, "authoritative
+   service-account state rejected issuance".
+2. **RAGcore admin UI**, this round, after the project owner explicitly authorized
+   Claude to self-issue the credential: the "Issue credential" form for the `fleet-ops`
+   application, submitted as the Platform Admin role (the highest role visible in the
+   RAGcore admin), with name `n8n-ragcore-procedure-sync` and scope `sources:sync` only.
+   Result: "Something went wrong. The credential could not be issued with those
+   values.", trace reference `1955c6a8968c4941a22a1faef39e17a7`.
+
+The `fleet-ops` application itself shows as ordinary/`Active` in the RAGcore admin, with
+no visible lock flag, and RAGcore's own OpenAPI spec documents no validation rule that
+would explain either rejection (no `422`, no field-level errors). Two independent paths
+— a raw API call and the admin UI as the top admin role — hitting the same failure
+signature is conclusive evidence this is a RAGcore-side policy or bug, not a Fleet Ops
+request-shape or permission problem. It is not fixable from the Fleet Ops side or
+through further UI automation. Resolving it requires whoever operates the RAGcore
+instance to look up the trace ID above (and the earlier raw-API rejection) in RAGcore's
+own logs.
+
+The real RAGcore contract this workflow will be built against — once a working
+credential exists — was independently inspected via RAGcore's live OpenAPI spec and is
+recorded in `docs/live-ai-integration/n8n-current-state.md` and
+`contracts/ragcore-contract-assumptions.md`: control-plane endpoints require an
+`Idempotency-Key` header; ingestion is `POST /v1/uploads`; retrieval is `POST
+/v1/search` / `/v1/context` / `/v1/answers` (the latter requiring `requested_space_ids`,
+an array of knowledge-space UUIDs); health is `/health/live` and `/health/ready` (not
+`/health`); the scope enum is `search, context, answer, documents:read, citations:read,
+feedback:write, sources:sync`.
+
+**`RAGcoreKnowledgeProvider` adapter** (`backend/app/services/knowledge/ragcore.py`)
+still targets the earlier speculative contract (`/health`, `POST /api/v1/ask`, Bearer
+token) rather than the real one above. This was deliberately **not** rewritten this
+round: rewriting it blind, without a credential to validate against, risks introducing
+a silent behavioral bug in exactly the code path responsible for the project's "AI must
+never invent an answer when RAGcore is unavailable or returns insufficient evidence"
+guarantee — for example a wrong `evidence_state` mapping that looks fine in code review
+but misclassifies "unavailable" as "insufficient" (or vice versa) against the real
+response shape. The adapter's current behavior is honest and safe (it degrades cleanly
+to `unavailable` on any request or parsing failure, and `ragcore_api_token` is unset by
+default so the app correctly runs on the local demo knowledge provider today). The
+rewrite stays queued behind the same credential blocker as workflow 3.
+
+## Workflow 4 — Workflow Error Handler
+
+Live workflow ID `Xppn2rAEqUuyiCJF`. Built and live-validated in an earlier round:
+Error Trigger → a Code node that derives a bounded, secret-free failure report (error
+category classified from the message text, truncated summary, no stack trace, no
+headers or tokens) → an HTTP call to Fleet Ops's `/workflow-error` endpoint (Header Auth
+via the same `Fleet Ops Service Token` credential), which registers the failure as an
+audit event idempotently keyed on `execution_id`.
+
+Set as the Error Workflow on both workflow 1 and workflow 2. Confirmed workflow 4 has no
+Error Workflow of its own (prevents a recursive loop).
+
+**Live validation performed**: a pinned mock Error Trigger payload produced a real `200
+{"status":"registered", ...}` from the live Fleet Ops server; re-running the identical
+payload produced `"status":"already_registered"`, confirming idempotency. A genuine
+induced failure (temporarily pointing workflow 2's HTTP node at a nonexistent path, then
+reverting) confirmed workflow 2 itself fails correctly against a broken endpoint and
+recovers cleanly once reverted.
+
+**Known limitation**: n8n's Error Workflow trigger does not fire for manual editor
+"Execute workflow" test runs — checked via workflow 4's own Executions list after the
+induced workflow-2 failure, and confirmed no new execution appeared. n8n only invokes a
+workflow's assigned Error Workflow for unattended/production trigger executions, not
+manual test runs from the editor. The mock-data path exercises the same nodes, logic,
+and real Fleet Ops endpoint, but a fully automatic (schedule- or webhook-triggered)
+failure cascading into workflow 4 was not observed live in either round.
+
+**Open follow-up (minor, non-blocking)**: continuing this round's acceptance pass to
+workflow 4 found the same timeout/retry gap as workflows 1 and 2 on its own outbound
+HTTP call. A fix was started (15000ms timeout added, Retry On Fail toggled on) but n8n's
+autosave began failing with "Unauthorized" mid-edit; a fresh browser tab confirmed the
+n8n session had expired (redirected to `/signin`). Nothing was saved — workflow 4's live
+definition is unchanged from before this round, so there is no partial or broken state.
+This is lower-stakes than workflows 1/2 (workflow 4 is the error notifier itself, not a
+primary business flow, and a failed error-report is already visible in n8n's own
+execution history via `On Error: Stop Workflow`) but should be finished once the n8n
+browser session is re-authenticated.
+
+## Repository source of truth
+
+`n8n/workflows/` holds cleaned, credential-value-free JSON definitions for all built
+workflows, `n8n/workflows/MANIFEST.md` documents purpose/trigger/contract/credentials/
+live-ID/checksum for all four canonical workflows (including workflow 3's blocked
+status), and `n8n/workflows/check_drift.py` is a read-only script that compares the
+repo definitions against the live instance via n8n's Public API and reports drift —
+safe to run in CI as a non-blocking check. No literal export/download mechanism was
+found working in this n8n version, so each definition was reconstructed from direct,
+verified UI inspection rather than a native export; this limitation is noted in the
+manifest itself.
+
+## Integration status page
+
+`/automation` (Operations Manager only) surfaces real per-workflow evidence derived
+purely from Fleet Ops's own audit/outbox tables — no new dependency on n8n's API was
+added to the backend. Each of the four canonical workflows shows a status (not built /
+no evidence yet / operational) and a last-evidence timestamp; the scheduled-scan
+evidence specifically filters to `actor_type == "service"` so a manually-triggered scan
+in the UI doesn't count as n8n evidence. An error-handler summary line reports total
+registered automation failures and the most recent one.
+
+Verified live in the browser (Dutch locale) both locally and on the deployed
+production server (`http://192.168.10.150:1236/automation`): correctly showed "3 van 4
+canonieke n8n-workflows hebben actuele evidentie van werking" with real timestamps for
+the return/scan/error-handler workflows, "Nog Niet Gebouwd" for the RAGcore sync, and
+the real error-handler registration from this effort's live testing.
+
+## Deployments performed (all explicitly user-approved)
+
+1. Backend `/workflow-error` endpoint (commit `bbdb4a9`) — deployed and verified
+   (`/health` OK, new endpoint returns `422` not `404` on an empty POST body).
+2. Integration status page, backend + frontend (commit `4049c0c`) — deployed and
+   verified (`/health` OK, page renders real evidence in the browser).
+
+The three n8n-side node edits this round (WF1 timeout/retry, WF2 timeout/retry, WF4's
+incomplete attempt) are live edits to the n8n instance itself and do not require a
+Fleet Ops redeploy.
+
+## What's left
+
+1. **RAGcore credential issuance** — blocked on RAGcore's own server-side rejection
+   (trace `1955c6a8968c4941a22a1faef39e17a7` and the earlier raw-API `400`). Needs
+   RAGcore's operator to investigate. Unblocks workflow 3 and the
+   `RAGcoreKnowledgeProvider` real-contract rewrite.
+2. **Workflow 4's own timeout/bounded-retry hardening** — needs the n8n browser session
+   re-authenticated to finish; a small, well-understood, non-blocking edit.
+3. **Fleet Ops logo/favicon** — explicitly deferred by the project owner as a separate,
+   unrelated follow-up task, not part of this integration effort.

-    RAGcore is built and owned separately (see contracts/ragcore-contract-assumptions.md).
-    No live RAGcore instance was reachable during this build, so the exact request/response
-    shape below is a best-effort guess at a REST contract; any failure (connection, timeout,
-    malformed response) degrades to `unavailable` rather than raising, per the architecture's

+    RAGcore's `/v1/search` retrieval, which is a materially different, simpler pipeline
+    stage with no generation step to fail. The fallback answer is always an extractive
+    excerpt RAGcore's own search actually found, wrapped in the same fixed citation
+    template `DemoKnowledgeProvider` uses -- never a fabricated summary.
+
+    Known gap, not fixable from this side: RAGcore's ingest pipeline currently tags every
+    chunk's `language` payload field as `"en"` regardless of actual document language (the
+    `/v1/uploads` contract has no per-file language field for a caller to set correctly).
+    Filtering search/answer requests by requested UI language would therefore silently
+    exclude genuinely-relevant nl-BE/fr-BE content, so this adapter deliberately does not
+    filter by language -- retrieval relies on the embedding model's cross-lingual matching.

+recommendation can never structurally disagree (see docs/fleet-ops-correction/
+vehicle-status-decision-table.md for the full decision table and rationale).
+
+The evaluator only ever reasons from real, freshly-queried domain facts (an actually
+active rental, a real service-threshold breach, a real overlapping-booking conflict) --
+never from a proxy like "does some other high-severity issue happen to be open". It is
+therefore also order-independent: resolving, deferring or rejecting an unrelated issue on

+## Prepared demo failure versus real failure
+
+The demo seed deliberately plants exactly one failed delivery (`BK-H-0020`, see
+`seed/workflow_runs.csv`). It exists to demonstrate retry and audit, so it must never be
+read as evidence that the automation is unhealthy.
+
+It is distinguished by its `last_error_code`, `demoScenarioTimeout`
+(`app.models.outbox.DEMO_SCENARIO_ERROR_CODE`) — not by a new column, so no migration is
+involved. A real timeout produces `connectionError`; the two are never confused.
+
+Consequences, all enforced by tests:
+
+- `/api/v1/integrations/status` reports `failed` (everything), `unexpected_failed` (real
+  failures only) and `demo_scenario_failed` separately.
+- Only `unexpected_failed` can move n8n off `operational`. A prepared failure alone
+  leaves the integration **operational** — a staged prop may not raise a red flag.
+- `latest_failure_at` is a health signal and therefore ignores the prepared failure;
+  `latest_demo_scenario_at` reports it separately.
+- `/api/v1/workflows` marks the run with `is_demo_scenario: true`. The Automation page
+  labels it "Prepared demo scenario", explains that it is a simulated temporary failure,
+  and offers a distinct "Retry demo scenario" action.
+- A genuine later failure of that same event overwrites the code with the real one, and
+  from that moment it counts as a real failure — the carve-out is narrow by construction.
+
+The retry itself is real in both cases: the event goes back on the outbox and the
+dispatcher delivers it to the configured n8n webhook like any other, so 19 succeeded +
+1 failed becomes 20 succeeded + 0 failed only when n8n genuinely accepts the delivery.
+Nothing is marked succeeded without a real round trip. The audit entry records
+`demo_scenario: true/false` so a staged retry is never mistaken for a production fix.
+A demo reset recreates the original 19 + 1 scenario.

+# MobilityOps visual product roadmap
+
+## Purpose
+
+This roadmap turns the visual audit of the deployed MobilityOps PoC into an
+implementation plan. It improves the existing operational workflows without
+expanding the locked product scope.
+
+The intended outcome is a platform that:
+
+- lets an operator identify and act on urgent work within thirty seconds;
+- remains efficient with the current synthetic data set and larger realistic data sets;
+- keeps status, context and primary actions visible on desktop and mobile;
+- uses a readable, consistent visual hierarchy;
+- communicates integration and knowledge health without contradictory signals;
+- preserves the existing domain rules, audit guarantees and graceful degradation.
+
+## Scope guardrails
+
+Included:
+
+- information architecture and visual hierarchy;
+- list density, pagination, filtering and responsive presentation;
+- dashboard, detail, return, data-quality, knowledge, automation, audit and demo flows;
+- accessibility, perceived performance and UI observability;
+- regression tests, visual evidence and rollout safeguards.
+
+Excluded:
+
+- new accounting, payments, CRM, inventory, HR or reservation modules;
+- maintenance work orders, calendar views or advanced analytics;
+- changes to RAGcore or ITWorx MCP Hub repositories;
+- autonomous write actions or write-capable MCP tools;
+- a redesign of backend domain rules that is not required by the UI work.
+
+## Audit baseline
+
+The audit was performed against the deployed application at desktop, tablet and
+mobile widths. The current strengths to preserve are the professional visual
+identity, consistent status language, strong login page, semantic page structure,
+visible keyboard focus, absence of horizontal overflow and clear return and
+data-quality narratives.
+
+The principal improvement signals are:
+
+| Area | Baseline observation | Consequence |
+|---|---|---|
+| Audit log | Up to 100 expanded event cards; approximately 18,500 px desktop and 20,500 px mobile | Poor scanability and excessive scrolling |
+| Vehicle list | All 50 vehicles render at once; approximately 12,000 px on mobile | Operational lookup is slow on small screens |
+| Mobile page header | `.page-actions` is hidden below 700 px | Important record status disappears |
+| Typography | Many metadata labels and badges are approximately 9–11 px | Readability is weaker than the visual quality suggests |
+| Top bar | Search, language, demo controls, disclosure, timezone and operator controls compete for space | High cognitive load and weak prioritisation |
+| Knowledge | An operational provider can be shown beside “0 procedures indexed” | Trust signal is ambiguous or contradictory |
+| Integration cards | Technical identifiers and small prose dominate the summary | Operational state is harder to scan |
+
+These values are baselines, not permanent acceptance thresholds. Each affected
+phase must record a before-and-after measurement.
+
+## Delivery principles
+
+1. Fix operational friction before decorative polish.
+2. Prefer progressive disclosure over removing useful evidence.
+3. Keep the primary status and next action visible at every viewport.
+4. Paginate or virtualise unbounded collections; never solve them only with CSS.
+5. Derive every displayed count and state from persisted or external evidence.
+6. Preserve URLs, permissions, audit semantics and keyboard operation.
+7. Ship each phase as a coherent, independently reversible commit.
+8. Validate every phase at 390 px, 768 px and 1440 px.
+
+## Target measures
+
+The roadmap is complete when the following targets are met:
+
+| Measure | Target |
+|---|---|
+| Initial rows/cards in any operational list | At most 25, unless a documented compact virtualised view is used |
+| Mobile status visibility | Primary record status visible on every detail page |
+| Horizontal overflow | None at 360 px and above |
+| Default text | At least 14 px |
+| Secondary metadata | At least 12 px; exceptions require an accessibility justification |
+| Touch target | At least 44 by 44 CSS px for primary mobile controls |
+| Keyboard access | All actions reachable with visible focus and logical order |
+| List navigation | Filter, paging and search state represented in the URL where practical |
+| Dashboard comprehension | Primary operational risks and next movements visible without scrolling at 1440 × 900 |
+| Browser console | No application errors during the five-minute demo |
+| Performance | No avoidable rendering of more than one page of list records |
+| Automated acceptance | Existing backend, frontend and Playwright gates remain green |

+
+## R0 — Baseline and design-system guardrails
+
+### Objective
+
+Create shared UI rules and reproducible measurements before changing individual
+pages.
+
+### Work packages
+
+#### R0.1 — Visual regression baseline
+
+- Capture authenticated reference screenshots for the seven principal routes and
+  the login page at 390 × 844, 768 × 1024 and 1440 × 900.
+- Add stable screenshot fixtures using the deterministic seed.
+- Mask only genuinely variable timestamps; do not mask operational content.
+- Record viewport width, page height, visible item count and horizontal overflow.
+
+#### R0.2 — Typography and spacing tokens
+
+- Replace scattered sub-12 px declarations with named type tokens.
+- Establish body, metadata, label, badge, table-header and navigation sizes.
+- Define compact and comfortable density variants without duplicating page CSS.
+- Preserve the existing petrol/teal palette and status colours.
+
+#### R0.3 — Shared responsive patterns
+
+- Define a mobile page-header contract: title, visible status, primary action and
+  overflow actions.
+- Define reusable compact-list, filter-toolbar, pagination and empty-state patterns.
+- Establish 44 px mobile target sizing and a consistent sticky-offset system.
+
+### Acceptance criteria
+
+- Visual baselines exist for all principal routes and viewports.
+- No normal operational metadata is smaller than 12 px.
+- Shared components document their responsive behaviour.
+- Existing Playwright demo and frontend build pass unchanged.
+
+## R1 — Operational lists and audit log
+
+### Objective
+
+Make high-volume operational information scannable and bounded on every device.
+
+### Work packages
+
+#### R1.1 — Audit API pagination and filtering
+
+- Replace the default fixed `limit=100` response with cursor or page-based pagination.
+- Add filters for date range, action, actor, entity type, entity reference and
+  correlation ID.
+- Retain stable newest-first ordering and service-token protections.
+- Return total or continuation metadata suitable for the selected paging model.
+
+#### R1.2 — Compact audit timeline
+
+- Render 20–25 compact events per page.
+- Group correlated events and repetitive scheduled events without hiding their count.
+- Move full UUIDs, before/after data and technical metadata into a details drawer.
+- Keep human-readable action, actor, target, outcome and timestamp in the main row.
+- Preserve direct navigation to related records.
+
+#### R1.3 — Vehicle-list pagination
+
+- Add server-compatible pagination to the vehicle list.
+- Preserve status, location, attention and search filters across pages.
+- Store filter and page state in the URL.
+- Provide a prominent “attention required” view without inventing new metrics.
+- Use compact mobile rows rather than full table-to-card expansion for every vehicle.
+
+#### R1.4 — Data-quality queue controls
+
+- Paginate the open issue list.
+- Add severity and rule grouping/filtering.
+- Add “previous issue” and “next issue” navigation to review pages.
+- Keep scan and resolution actions permission-aware.
+
+### Acceptance criteria
+
+- No default list renders more than 25 records.
+- Audit and vehicle pages remain below 3,500 px at the tested mobile viewport with
+  the deterministic seed.
+- Paging and filters survive reload, back navigation and direct links.
+- Empty, loading, error and end-of-results states are explicit.
+- API tests cover invalid cursors/pages, combined filters and authorization.
+
+## R2 — Responsive shell and readable hierarchy
+
+### Objective
+
+Reduce navigation noise and keep essential context visible on small screens.
+
+### Work packages
+
+#### R2.1 — Top-bar simplification
+
+- Keep global search and current operational context primary.
+- Move language, timezone and sign-out into the operator menu.
+- Combine demo disclosure and demo progress into one compact control.
+- Replace the visually empty mobile search field with an explicit search button or
+  a full-width command surface.
+
+#### R2.2 — Mobile page actions
+
+- Stop hiding the complete page-action region.
+- Always show record status next to or below the title.
+- Keep one primary action visible and move secondary actions to an accessible menu.
+- Verify booking, vehicle, data-quality and automation detail headers independently.
+
+#### R2.3 — Navigation refinement
+
+- Review whether the desktop sidebar should remain available at wider tablet widths.
+- Increase mobile navigation label size and touch area.
+- Keep four or five primary destinations visible and put lower-frequency destinations
+  under “More” if six items cannot meet readability targets.
+- Preserve current routes and role-based visibility.
+
+#### R2.4 — Typography rollout
+
+- Apply the R0 type tokens to badges, tables, integration cards, timelines, forms and
+  mobile navigation.
+- Rebalance padding where larger text would otherwise increase page height excessively.
+- Verify Dutch, French and English labels for clipping and wrapping.
+
+### Acceptance criteria
+
+- Status remains visible on every sampled mobile detail page.
+- No essential action is hover-only or hidden solely because of viewport width.
+- Top-bar controls fit without clipping at 390, 768 and 1440 px.
+- Language changes do not introduce horizontal overflow.
+- Touch-target and typography targets are met.
+
+## R3 — Dashboard and record-detail efficiency
+
+### Objective
+
+Put operational decisions above supporting detail and make desktop space work harder.
+
+### Work packages
+
+#### R3.1 — Dashboard hierarchy
+
+- Keep readiness and highest-severity attention items visible in the first viewport.
+- Reduce the vertical weight of the demo-scenario panel after the scenario starts.
+- Limit the initial attention queue and link to a complete filtered view.
+- Balance “movements today” against attention content when only a few movements exist.
+- Keep integrations and recent activity available without duplicating status copy.
+
+#### R3.2 — Mobile dashboard summary
+
+- Convert readiness into a compact, horizontally accessible summary or disclosure.
+- Show the highest-priority attention items first with an explicit remaining count.
+- Surface the next departure and return before secondary integration information.
+
+#### R3.3 — Vehicle-detail workspace
+
+- Replace the sparse overview with a two-column desktop composition.
+- Surface current status, location, odometer, next booking and active attention items.
+- Keep bookings, inspections, maintenance, quality issues and audit as focused tabs.
+- Avoid new maintenance-domain functionality; link only to existing evidence.
+
+#### R3.4 — Booking-detail summary
+
+- Rebalance the facts grid so incomplete final rows do not create large empty bands.
+- On mobile, show status and return readiness before secondary booking facts.
+- Keep the return form close to the task entry point while retaining validation context.
+
+### Acceptance criteria
+
+- At 1440 × 900 the dashboard exposes readiness, urgent work and today's movement
+  context without scrolling.
+- Sparse states remain intentional and balanced rather than appearing unfinished.
+- All values remain derived from persisted data.
+- Existing return and status-domain tests remain unchanged and green.
+
+## R4 — Guided workflows and decision surfaces
+
+### Objective
+
+Reduce the distance between evidence and the decision an operator must make.
+
+### Work packages
+
+#### R4.1 — Return flow refinement
+
+- Keep the step indicator visible while completing or reviewing a return.
+- Use a compact mobile booking summary above the form.
+- Present validation errors next to fields and in a short focusable summary.
+- Preserve the post-submit explanation of inspection, vehicle status, quality issue,
+  queued automation and next-booking risk.
+
+#### R4.2 — Duplicate-customer decision layout
+
+- Use evidence/comparison on the left and a sticky survivor/merge preview on desktop.
+- Keep matching fields collapsed by default and differences expanded.
+- Keep irreversible-action language and audit preview adjacent to the merge button.
+- On mobile, use a deliberate sequence: evidence, differences, survivor, preview,
+  confirmation.
+
+#### R4.3 — Other data-quality resolutions
+
+- Standardise evidence, proposed resolution, consequence and audit-preview sections.
+- Keep resolve, reject and defer actions visually distinct and permission-aware.
+- Provide clear success feedback and navigation to the next issue.
+
+#### R4.4 — Guided demo integration
+
+- Reduce competition between the guide and normal navigation.
+- Persist progress without obscuring page controls.
+- Make “go to this step” land on the relevant element or focused task state.
+- Ensure the guide is fully keyboard-operable and usable as a mobile bottom sheet.
+
+### Acceptance criteria
+
+- Primary workflow action is visible or reachable with one obvious interaction.
+- A user never needs to scroll past repeated explanatory content to discover the
+  required decision.
+- Focus moves to validation failures and success results appropriately.
+- The five-minute demo remains deterministic.
+
+## R5 — Knowledge, automation and trust signals
+
+### Objective
+
+Make external-system health understandable to an operator without exposing irrelevant
+technical detail.
+
+### Work packages
+
+#### R5.1 — Knowledge status semantics
+
+- Separate provider availability, indexed-source count and last successful sync.
+- Never show “0 indexed” as a healthy equivalent when the value is unknown or stale.
+- Label extractive fallback answers honestly while preserving source cards.
+- Reduce empty-state height and show a compact explanation of what a cited answer contains.
+- Keep suggested questions concise and prioritised.
+
+#### R5.2 — Source and freshness presentation
+
+- Surface source title, version, section and freshness consistently.
+- Keep document UUIDs and raw retrieval metadata behind technical details.
+- Provide explicit grounded, insufficient-evidence and unavailable states.
+
+#### R5.3 — Integration summary redesign
+
+- Structure each integration around state, last success, affected workflow and next action.
+- Move client IDs, raw endpoints and UUIDs to a detail disclosure.
+- Remove unnecessary fixed card height, especially at tablet widths.
+- Keep genuine mixed states visible without presenting them as contradictions.
+
+#### R5.4 — Workflow evidence table
+
+- Improve status and recency scanning.
+- Distinguish “never triggered”, “no evidence yet”, “failed” and “unavailable”.
+- Keep retry actions safe, audited and available only where already supported.
+
+### Acceptance criteria
+
+- Knowledge and integration states cannot make mutually contradictory claims.
+- An operator can identify the current state and next action within one card scan.
+- Technical identifiers do not dominate default views.
+- RAGcore, n8n and MCP Hub timeout/unavailable contract tests stay green.
+
+## R6 — Accessibility, performance and release evidence
+
+### Objective
+
+Turn the improvements into a verified, releasable quality baseline.
+
+### Work packages
+
+#### R6.1 — Accessibility review
+
+- Test complete keyboard traversal of login, navigation, filters, return, merge,
+  knowledge, workflow retry and audit details.
+- Verify focus order, focus restoration, dialog labelling and error announcements.
+- Run automated accessibility checks on all principal routes.
+- Manually verify status is not encoded by colour alone.
+- Verify zoom at 200% and 360 px responsive reflow.
+
+#### R6.2 — Rendering and interaction performance
+
+- Measure list rendering before and after pagination.
+- Check layout shift and interaction latency on dashboard and long-list routes.
+- Ensure drawers, menus and guided-demo panels do not mount large hidden subtrees.
+- Test with reduced motion and a throttled CPU profile.
+
+#### R6.3 — Cross-browser and localisation pass
+
+- Verify current Chrome plus one additional Chromium/Firefox-equivalent target where
+  supported by the test environment.
+- Run Dutch, French and English visual checks at all target widths.
+- Verify Europe/Brussels date and time rendering.
+
+#### R6.4 — Final automated journey and evidence
+
+- Extend the existing Playwright demo with pagination, mobile status and accessible
+  details checks.
+- Capture final screenshots for all principal pages.
+- Add before-and-after measurements and known PoC limitations to final evidence.
+- Execute clean-checkout bootstrap, backend tests, lint, typing and frontend build.
+
+### Acceptance criteria
+
+- No critical or serious automated accessibility violations on principal routes.
+- All target measures in this document pass.
+- `docs/14-testing-and-acceptance.md` passes from a clean checkout.
+- `artifacts/evidence/final-summary.md` contains the final commands, counts,
+  screenshots and limitations.
+
+## Suggested release slices
+
+### Release A — Operational scale
+
+Contains R0 and R1. This release eliminates the most severe scroll and list-density
+problems without materially changing workflow structure.
+
+Release gate:
+
+- paginated audit, vehicles and data-quality queues;
+- URL-backed filters;
+- unchanged audit and authorization semantics;
+- visual regression baseline green.
+
+### Release B — Responsive operations
+
+Contains R2 and R3. This release improves navigation, typography, dashboard hierarchy
+and detail-page use of space.
+
+Release gate:
+
+- visible mobile statuses and primary actions;
+- readable typography and touch targets;
+- dashboard first-viewport target met;
+- Dutch, French and English responsive checks green.
+
+### Release C — Guided decisions and trust
+
+Contains R4 and R5. This release refines the return, merge, knowledge, automation and
+demo-guide experiences.
+
+Release gate:
+
+- decision actions remain near their evidence;
+- honest and non-contradictory external health states;
+- five-minute demo passes end to end.
+
+### Release D — Quality certification
+
+Contains R6 and only defects found by its gates. It adds no new product scope.
+
+Release gate:
+
+- full clean-checkout acceptance;
+- accessibility and performance targets met;
+- final evidence updated;
+- release tag and deployed revision recorded.
+
+## Implementation sequence and dependencies
+
+```text
+R0 shared tokens and baselines
+ ├─ R1 pagination and compact lists ─┐
+ └─ R2 responsive shell and type ───┼─ R3 dashboard/details ─ R4 workflows
+                                    └─ R5 trust surfaces
+R1 + R2 + R3 + R4 + R5 ──────────────────────────────── R6 release gate
+```
+
+R1 and R2 may be developed in parallel after R0. R3 should consume both shared list
+and responsive patterns. R4 depends on the new page-header and detail hierarchy. R5 can
+start after R2 but must share its disclosure and status patterns. R6 is a gate, not a
+cleanup bucket; defects discovered there return to the owning phase.
+
+## Per-phase engineering checklist
+
+Every phase must include:
+
+1. a short before-state measurement;
+2. API and data-contract impact assessment;
+3. implementation using shared components where applicable;
+4. unit/API tests for changed contracts;
+5. Playwright coverage for the changed user journey;
+6. manual checks at 390, 768 and 1440 px in all supported languages;
+7. accessibility and console check;
+8. updated evidence and `PROJECT_STATE.md` entry;
+9. one coherent commit after validation passes;
+10. deployment verification before starting the next release slice.
+
+## Risks and mitigations
+
+| Risk | Mitigation |
+|---|---|
+| Pagination changes API consumers | Add pagination metadata without silently changing service-token/MCP response contracts; version only if necessary |
+| Compact layouts hide evidence | Use drawers and disclosures, preserving direct access and auditability |
+| Larger type increases page height | Combine type changes with density and hierarchy work, never shrink text again |
+| Sticky UI covers content on mobile | Use shared top/bottom offsets and test keyboard/zoom states |
+| Visual snapshots become brittle | Seed deterministic data and mask only true timestamp volatility |
+| External health data is stale | Show last successful evidence and distinguish unknown from healthy |
+| Roadmap drifts into new product scope | Check every work package against `docs/01-scope-and-non-goals.md` and `docs/deferred.md` |
+
+## Definition of roadmap completion
+
+This roadmap is complete only when Releases A through D are deployed and verified,
+all target measures pass, the original five-minute demo remains green, and the final
+evidence records the exact deployed revision. Completing only the visual styling or one
+high-priority page does not complete the roadmap.

+# AI Operations Brief — runbook and live evidence
+
+Answers, using a real MCP client through the real ITWorx MCP Hub connector against live
+production Fleet Ops: *"Which vehicles need the most attention today, why, and which
+internal procedure should be followed for the most important issue?"*
+
+## What this is not
+
+Not a chatbot. No write actions exist under `/api/v1/integrations/mcp/*` (verified by
+`test_no_write_endpoints_exist_under_mcp_namespace`). Every call below is a plain
+read-only tool invocation, exactly as the deployed Hub connector performs them.
+
+## Reproducible command
+
+Run from inside the live `itworx-mcp-hub-connector-mobilityops-1` container (has the
+real `MOBILITYOPS_ENDPOINT`, `MOBILITYOPS_SERVICE_TOKEN_FILE` and the real
+`packages.connector_kit.mobilityops.MobilityOpsClient` already available — the same
+client class the deployed connector uses):
+
+```sh
+docker exec -e PYTHONPATH=/opt/hub -w /opt/hub \
+  itworx-mcp-hub-connector-mobilityops-1 python3 - <<'PY'
+from packages.connector_kit.mobilityops import FileTokenProvider, MobilityOpsClient, MobilityOpsSettings
+import os, json
+
+settings = MobilityOpsSettings(
+    base_url=os.environ["MOBILITYOPS_ENDPOINT"],
+    token_reference=os.environ["MOBILITYOPS_SERVICE_TOKEN_FILE"],
+)
+client = MobilityOpsClient(settings, FileTokenProvider())
+client_id = "ai-ops-brief"
+
+summary = client.operations_summary(client_id)
+attention = client.attention_vehicles(client_id, minimum_severity="high", date=None, limit=20)
+top_ref = attention[0]["vehicle_ref"] if attention else None
+details = client.vehicle_details(client_id, top_ref) if top_ref else None
+answer = client.search_knowledge(client_id, "What must I do when a vehicle returns with damage?", max_sources=2)
+
+print(json.dumps({"summary": summary, "top_attention": attention[0] if attention else None, "vehicle": details, "answer": answer}, indent=2))
+client.close()
+PY
+```
+
+This calls, in order: `fleet_ops_get_operations_summary` → `fleet_ops_list_attention_vehicles`
+→ `fleet_ops_get_vehicle_details` → `fleet_ops_search_knowledge`. No result is invented —
+every field printed is exactly what Fleet Ops's live API returned.
+
+## Live run, 2026-08-05
+
+- **Operations summary**: 21 available, 11 rented, 6 cleaning, 5 maintenance,
+  **7 blocked**; 23 open quality issues; 1 pending/failed workflow.
+- **Most pressing vehicle**: `MO-031` — `missing_required_field`, "near-future booking;
+  required operational inspection missing", detected `2026-08-05T11:08:33Z`. (16 vehicles
+  currently carry a `high`-severity open issue; `MO-031` was the earliest-detected.)
+- **Vehicle detail (`MO-031`)**: Adria Matrix, 2022, Geel, `operational_status: blocked`,
+  41,149 km (service due at 50,000 km), no current booking.
+- **Grounded procedure (English)**: *Damage handling procedure* v1.3, section "1.
+  Immediate actions" — "When a vehicle returns with visible or reported damage, mark
+  damage in the return inspection, add a concise factual description and keep the
+  vehicle blocked. Do not promise the customer a repair cost or liability decision."
+  Second source: *Vehicle return procedure* v2.0, section "3. Determine next state".
+  `evidence_state: grounded`, 2 real citations, `provider: demo`.
+- **Dutch and French variants of the damage question** (`Wat moet ik doen wanneer een
+  voertuig beschadigd terugkomt?`, `Que dois-je faire lorsqu'un véhicule revient
+  endommagé ?`) both returned `evidence_state: insufficient` — an honest, non-fabricated
+  "no match" rather than a wrong or invented answer. Root cause: the currently-deployed
+  Hub connector does not yet send the new `locale` field this session added to
+  `search-knowledge` (Fleet Ops defaults to `en-GB`), so non-English question text
+  doesn't match the demo provider's English-tokenized index. A real fix needs a Hub-side
+  connector update to pass `locale`, tracked as a follow-up, not silently worked around.
+- **Correlation ID, end to end, verified**: each call's response `correlation_id` (e.g.
+  `abd643a7-2aeb-4af3-806a-da04acb3e444` for the English grounded answer) appears
+  verbatim in Fleet Ops's own audit log (`GET /api/v1/audit?action=mcp_tool_request`),
+  alongside `actor_label: ai-ops-brief-2026-08-05` and the real tool name
+  (`fleet_ops_search_knowledge`). No write actions were performed; only `mcp_tool_request`
+  audit rows were created, matching every other live MCP call this integration makes.
+
+## Known limitation, stated plainly
+
+The demo knowledge provider (not RAGcore — `KNOWLEDGE_PROVIDER=demo`, see
+`docs/final-integrations/current-state-audit.md` for why) is what grounds the English
+answer here. It is deterministic, extractive, and never fabricates — but it is not the
+live RAGcore integration the brief brief for this task set out to exercise; that
+remains blocked on RAGcore's own reranker gap. This run is honest about that: it proves
+the full MCP-client → Hub → Fleet Ops → knowledge-provider → audit chain works for real,
+live, in production, with real data and real citations — using the knowledge provider
+that is actually configured live today.

+
+## Branch-name correction (recorded assumption)
+
+The task brief names the working branch `feat/fleet-ops-final-integrations` as already
+selected and "branched from the most recently validated, localized, deployed master
+branch." That literal branch did not exist. `master` is in fact stale (19 commits behind,
+last touched for a localization round only) — the actually-validated, deployed line of
+work is `feat/live-n8n-ragcore-integration` (pushed to `origin`, deployed to
+`http://192.168.10.150:1236` at `0571a40`, one commit behind current HEAD). Created
+`feat/fleet-ops-final-integrations` from that branch's HEAD (`3ebca9e`) instead of from
+`master`, since that satisfies the actual intent (continue from the validated/deployed
+line) even though the literal branch name in the brief was inaccurate.
+
+## What is actually already done (contradicts "not yet live" framing in places)
+
+- **n8n**: 3 of 4 canonical workflows are live and active in the shared instance
+  (`n8n.itworx.tech`): Vehicle Return Orchestration, Scheduled Data Quality Scan,
+  Workflow Error Handler. The 4th, RAGcore Procedure Sync, has all 6 nodes built and
+  saved but is **not published** (deliberately left for an explicit activation decision,
+  since publishing starts real unattended daily runs against production). The root cause
+  of an earlier "auth"-looking failure (`N8N_PROXY_HOPS=0` behind the TLS-terminating
+  reverse proxy, breaking the browserId CSRF check on every mutating REST call) was found
+  and fixed at the infrastructure level (Unraid template), not worked around.
+- **RAGcore**: deployed to `http://192.168.10.150:1237`, application wiring for
+  search/context/answer is real (commit `a2905cc`, confirmed present in RAGcore's own
+  history at `13 commits behind HEAD`). `KNOWLEDGE_PROVIDER` is still `demo` in Fleet Ops
+  because real queries against the "Fleet Ops Procedures" space return **zero dense and
+  zero sparse candidates** at the raw retrieval stage — confirmed not a Fleet-Ops-side
+  wiring bug (RAGcore's own trusted Query Lab tool reproduces the identical zero-candidate
+  result against the same space). Root cause not yet found as of this audit; ruled out so
+  far: point count/scoping (83 published, correctly scoped), embedding digest mismatch
+  (matches), collection alias resolution (resolves correctly). One separate, confirmed,
+  pre-existing bug: `_DEFAULT_LANGUAGE = "en"` is hardcoded in RAGcore's ingestion handler
+  — every chunk is stamped `language: "en"` regardless of actual content; RAGcore has never
+  done real language detection. Not the cause of zero candidates, but must be fixed for
+  trilingual retrieval (task 6A) once the space is answerable at all.
+- **MCP Hub**: the Fleet Ops read-only connector (4 tools, `mobilityops.*`) is **already
+  live in production** on Tower (commit `c4a0f6d`), reachable via `fleetops.itworx.tech`,
+  end-to-end verified once already per the Hub's own `CLAUDE.md`/`BUILD_STATE.json`. A
+  real contract bug was found and fixed there (`vehicle.get`'s input schema disagreed with
+  the actual wire parameter name — `vehicle_ref` vs `vehicleRef`). What is **not** yet done:
+  the Hub's own formal production-acceptance checklist row for MobilityOps (`CON-P04`) has
+  not been executed, and Fleet Ops's own `MCP_HUB_REGISTRATION_ENABLED`/base-URL
+  configuration has not been confirmed as actually wired and flipped on from the Fleet Ops
+  side (open item for this audit's Batch 4).
+
+## Confirmed contradictions to resolve (task section 3)
+
+- "Twee versus vier n8n-workflows": resolved above — 3 active + 1 built-but-unpublished.
+  Canonical set is 4; only 3 are live.
+- "Demo-provider versus live RAGcore": Fleet Ops is still on the demo knowledge provider
+  by deliberate, documented decision (not an oversight) pending the retrieval root cause.
+- "MCP Hub-status": prior Fleet Ops docs (`.env.example`, `MCP_HUB_REGISTRATION_ENABLED`)
+  predate the Hub-side deployment and need reconciling against the fact that the connector
+  is already live on the Hub side.
+- Repo hygiene: removed an untracked, empty `backend;C` directory and an untracked 31 MB
+  `MobilityOps.zip` stray export; added `*.zip`/`*.tar.gz` to `.gitignore`. No accidentally
+  committed `__pycache__`/`.pytest_cache`/`test-results` were found in git history.
+
+## RAGcore retrieval root cause — found and partially fixed (2026-08-05, this session)
+
+Investigated live against production (`192.168.10.150`, containers `ragcore-app-1`,
+`ragcore-qdrant-1`, `ragcore-postgres-1`, `ollama`), read-only first, then two approved
+live changes.
+
+**Root cause #1 (FIXED): filesystem permission bug, not authorization/data.** Verified,
+in order, that every earlier suspect was actually healthy: the `control.grants` row
+(active, `editor` role, correct application/space), the real
+`ControlPlaneAuthorizationInputsProvider` + `RetrievalAuthorizationService.resolve()` code
+path run in-process against the live DB (resolves a non-empty `effective_space_ids`), the
+exact production Qdrant filter run directly against the live collection (returns real
+matching points), and a real ANN vector query under that filter (real hits, sensible
+scores). The actual break: `/workspace/.state/models/embedding_profiles.json` — the file
+`RetrievalPipeline.run()` reads on every single query to resolve the active embedding
+profile — was owned by container-side `root:root` mode `600` on the bind-mounted
+`/mnt/cache/appdata/ragcore/state/models` host path, while the real running app process
+is uid 10001 (`ragcore`). Every retrieval call hit a `PermissionError` reading its own
+state file before ever reaching Qdrant — a plain filesystem-ownership bug, invisible to
+every DB/Qdrant-level check. **Fixed live**: `chown 10001:10001` +
+`chmod 644`/`755` on that file/directory (approved by the user beforehand). Re-verified
+in-process: `RetrievalPipeline.run()` now returns 5 real, relevant hits for an English
+damage-procedure question (previously 0).
+
+**Root cause #2 (found, NOT fixed — needs a design decision): reranking is
+architecturally unavailable.** `DEFAULT_RERANKER_PROFILE.model_identifier` is
+`bge-reranker-v2-m3:v1`, which was never actually present in Ollama's model list (0 of 14
+installed models matched). With the user's approval, pulled a working GGUF
+(`xitao/bge-reranker-v2-m3:latest`, 1.2 GB) into the shared Ollama instance. **This did
+not fix reranking**: `OllamaRerankAdapter` posts to `{ollama_base_url}/api/rerank`, and
+this Ollama server (version `0.32.5`) returns a plain `404` for that route — it has no
+rerank endpoint at all. This is not a missing-model problem, it is that RAGcore's
+reranker adapter was built against an Ollama HTTP API that does not exist in the deployed
+version (matches the code's own comment that no reranker-profile registry or live
+validation existed yet). The retrieval pipeline degrades gracefully on rerank failure
+(RRF-fusion-only hits still returned, confirmed above), but the `/v1/answers` endpoint's
+answerability classifier still returns `not_answerable`/0 citations for real NL/EN/FR
+questions against real matching content, live-verified after fix #1 with a freshly
+minted, correctly-scoped credential.
+
+Options for #2, not decided yet: (a) find/confirm whether a newer Ollama version adds a
+real `/api/rerank` route and upgrade the shared instance (affects every other project on
+this Ollama — needs its own explicit approval and blast-radius review); (b) change
+RAGcore's reranker adapter to call a route Ollama actually supports (e.g. score via
+`/api/embed` + a manual similarity/cross-encoder computation, or drop the separate
+rerank step and let the answerability classifier trust RRF-fused scores) — a RAGcore
+code/design change, out of Fleet Ops's own mandate to decide unilaterally; (c) leave
+`KNOWLEDGE_PROVIDER=demo` until RAGcore's own team/session resolves this.
+
+**Side effect to flag**: minting the live-verification credential used `rotate=True` on
+the existing "Fleet Ops Knowledge Assistant (production)" service account (a second
+credential would have exceeded RAGcore's own 2-active-credential cap), which invalidates
+whatever token was previously issued for that account. Since Fleet Ops is still on
+`KNOWLEDGE_PROVIDER=demo`, this has no live user-facing impact today, but a fresh
+credential must be issued and wired into Fleet Ops's `RAGCORE_API_TOKEN` at actual
+cutover time — do not assume the old one still works.
+
+**Concurrency note**: `C:\Projects\RAGcore` had substantial uncommitted local changes
+from what appears to be a different, actively-running session (36 modified/untracked
+files by the end of this investigation, including files this investigation also read).
+No commits or file edits were made in that checkout this session precisely because of
+that collision risk — the two live fixes above were applied directly to the running
+containers/Ollama instance (approved), not to the RAGcore git repository. **Follow-up
+required**: once the concurrent session's work lands, the reranker-profile fix (whichever
+option above is chosen) still needs an actual code change + commit + redeploy in
+`C:\Projects\RAGcore`, which was not safe to do mid-collision this session.
+
+## Minimal remaining implementation order
+
+1. Root-cause the RAGcore zero-candidate retrieval bug (blocks flipping `KNOWLEDGE_PROVIDER`
+   and blocks the trilingual live-acceptance and AI Operations Brief tasks).
+2. Fix RAGcore's hardcoded `language: "en"` chunk metadata for trilingual retrieval.
+3. Decide on and execute n8n workflow 3 publication, with live no-op-on-rerun verification.
+4. Confirm/complete Fleet Ops-side MCP Hub registration wiring and run the Hub's own
+   CON-P04 acceptance row.
+5. Build the AI Operations Brief runbook once RAGcore and MCP Hub are both live-green.
+6. GUI polish batch (dashboard Today/Attention presentation, duplicate-merge presentation,
+   About Demo scannability, Demo Guide completion state).
+7. Final regression gates and evidence write-up.

+# Fleet Ops correction — current-state gap audit
+
+## Branch / commit state (at audit time)
+
+- Repository's actual main/default branch is named **`master`** (there is no `main` branch — `remotes/origin/HEAD -> origin/master`). All instructions referring to "main" in this task are treated as referring to `master`.
+- `master` (local and `origin/master`) was at `18344bc8b7a75a2f868bf15bf498fc030ac6c34c` before this task started — this is the newest verified Fleet Ops demo commit (contains the full rebrand/i18n/adaptive-guide/Data-Quality-UX work from the previous task).
+- Deployed commit on Unraid (`/mnt/user/appdata/mobilityops/.deploy/source-revision`): `18344bc8b7a75a2f868bf15bf498fc030ac6c34c` — matches `master` exactly. No drift.
+- No uncommitted local changes at audit time (`git status` clean).
+- Source branch for this correction: `master` (already contained the newest verified commit). New branch created: **`fix/fleet-ops-i18n-status-flow`**, branched from `master` at `18344bc`.
+- `feat/mobilityops-functional-completion` remains un-deleted, as instructed by the prior task, and is left untouched by this one.
+
+## Confirmed gaps (verified against actual code, not assumed)
+
+### 1. Brand name is a translatable key (structural risk)
+
+- `common:appName` exists per-locale in `frontend/src/i18n/locales/{nl-BE,en-GB,fr-BE}/common.json`, all currently `"Fleet Ops"`, but nothing prevents a future edit from diverging one locale. Used in `Login.tsx:35` and `Layout.tsx:180`.
+- 8 more locale keys embed the literal string "Fleet Ops" inside translatable prose (`auth.defaultDescription`, `common.footer.productLine`, `demo.guide.steps["review-real-vs-simulated"].expectedOutcome`, `demo.about.title`, `demo.about.problemBody`, `demo.about.scopeBody`, `knowledge.emptyDescription`, `navigation.searchLabel`, `returns.scenario.body`) — all three locales currently say "Fleet Ops" correctly, but structurally these are still translatable values.
+- **Fix**: `frontend/src/product.ts` exports `PRODUCT_NAME = "Fleet Ops"`. Remove `common:appName`; `Login.tsx`/`Layout.tsx` import the constant directly. Replace the 8 embedded mentions with `{{productName}}` interpolation, passing `productName: PRODUCT_NAME` explicitly at each call site. Add a Playwright test that fails if any locale JSON file contains the literal substring `"Fleet Ops"` (forcing all future brand mentions through interpolation) and a live-DOM test asserting the rendered brand text is byte-identical across all three languages.
+
+### 2. Backend hardcodes English prose as primary user-facing content (structural, not cosmetic)
+
+Confirmed in `backend/app/services/data_quality.py`:
+- `_scan_duplicate_customers` (~line 127-149): evidence signals literally `"exact email"`, `"exact phone"`, `"exact postal code"`, `"similar name"`, joined into `evidence.summary`.
+- `_scan_missing_required_fields` (~170, 185): `f"Missing: {', '.join(missing)}"`.
+- `_scan_booking_overlaps` (~213): `f"Overlapping bookings {first.public_ref} and {second.public_ref}"`.
+- `_scan_vehicle_status_conflicts` (~240-256): reason strings like `"marked available while an active booking exists"`.
+- `_scan_odometer_regressions` (~291-295): full English sentence with interpolated numbers/refs.
+- `_recommend_vehicle_status` (~659-668): recommendation `reason` strings returned verbatim as `ApplyRecommendedStatusResult.reason` and rendered directly in the UI.
+
+Confirmed in `backend/app/services/returns.py`:
+- `_derive_vehicle_status_with_reason` (~32-43): `status_reason` strings ("Damage was reported on return.", "A technical warning was reported on return.", "Odometer reached the {n} km service threshold.", "No damage, technical warning or service threshold; routed to cleaning.") flow straight into the API response and are displayed raw regardless of UI language (asserted verbatim in English in `interactive-elements.spec.ts:133`, confirming this is genuinely user-visible, not just internal).
+
+Confirmed in `backend/app/services/dispatcher.py` / seed data: `event.last_error` stores raw strings like `"Synthetic connection timeout to n8n"` from `seed/workflow_runs.csv`, rendered directly in `Automation.tsx` (`{r.last_error ?? "—"}`) with no localization or summarization.
+
+Frontend confirmed to display these values completely raw: `DataQualityIssueDetail.tsx` → `<dd>{String(issue.evidence.summary ?? "")}</dd>` — the *label* is translated, the *value* is not.
+
+**Fix**: introduce structured `signals`/`message_code`+`params` on evidence and reasons (data-quality evidence, status-conflict recommendation reason, return status reason, automation last-error), with a frontend mapping layer that localizes known codes and falls back to the raw string under "Technical details" only.
+
+### 3–5, 8A. Status-recommendation flow is unsafe and combines calculation with mutation
+
+- **Confirmed single mutating endpoint**: `POST /api/v1/data-quality/issues/{public_ref}/apply-recommended-status` (`backend/app/api/routers/data_quality.py`) computes the recommendation and mutates the vehicle in the same call. No separate preview/GET route exists for this flow (unlike the return flow, which already has `preview_vehicle_return` / `register_vehicle_return` sharing one pure evaluator).
+- **Confirmed unsafe shortcut** (explicitly prohibited by this task): `_recommend_vehicle_status` in `data_quality.py` returns `("rented", ...)` whenever `operational_status == "maintenance" and has_active_booking` — i.e. a vehicle flagged for maintenance with an active booking is auto-recommended (and, on one click, actually changed) to `rented`, with no check of the underlying reason it's in maintenance and no manual-review branch.
+- **Confirmed proxy-based reasoning** (explicitly prohibited): the `available` + `has_open_high_issue` → `blocked` branch depends only on "does some other open high-severity issue exist for this vehicle", not on real underlying facts (damage, technical warning, confirmed overlap). `data_quality.py` never imports `Inspection`, so damage/technical-warning facts are never examined by this function at all.
+- **Confirmed scanner/resolver duplication**: `_scan_vehicle_status_conflicts` and `_recommend_vehicle_status` are two independently-maintained `if`-chains (hand-kept-in-sync via a docstring comment, not shared code) — a structural fragility even though today's four branches happen to agree.
+
+**Fix**: new shared domain service `backend/app/services/vehicle_status.py` with one `evaluate_vehicle_status()` function consulting real facts (active/reserved/overlapping bookings, latest inspection damage/technical-warning, maintenance threshold, cleaning state), used by scanner, a new non-mutating preview endpoint, the apply endpoint, and tests. Maintenance+active-booking becomes `manual_review_required`, never an automatic `rented`. Full decision table in `docs/fleet-ops-correction/vehicle-status-decision-table.md`.
+
+### 6–7. MO-016 / issue-ordering
+
+- Confirmed `MO-016` scenario: vehicle seeded `operational_status="available"`, two overlapping *reserved* bookings (`BK-DEMO-OVERLAP-A`/`-B`), two pre-seeded `open` issues on the same vehicle (`DQ-DEMO-OVERLAP` booking_overlap, `DQ-DEMO-STATUS` vehicle_status_conflict).
+- Confirmed **no test** resolves both issues in sequence (either order) within one session to check the outcome stays deterministic — each existing test independently resets the demo data first.
+
+**Fix**: new evaluator is order-independent by construction (recomputes real facts every call, doesn't cache any prior issue's existence as an input other than the generic "another open high-severity issue for manual-review fallback"); add an explicit ordering test.
+
+### 8. i18n-coverage test doesn't prove translation happened
+
+Confirmed: `frontend/e2e/i18n-coverage.spec.ts` only checks key-parity and non-empty values — a locale file could contain the literal English string copy-pasted and the test would still pass. Locale files were manually verified as genuinely translated (no hits for probe phrases like "canonical odometer", "committed locally", "correlation ID" etc. in `nl-BE`/`fr-BE`), so this is a test-coverage gap, not an active mistranslation — but per this task's instructions it still needs closing.
+
+**Fix**: add a translation-quality test comparing `nl-BE`/`fr-BE` values against `en-GB` for meaningful divergence (with an explicit allowlist for real proper nouns/technical tokens: Fleet Ops, Northstar Mobility, n8n, RAGcore, MCP Hub, API, UUID, Docker, PostgreSQL), plus a route-matrix smoke test opening every main route in all three languages.
+
+### 9. One confirmed leftover hardcoded string
+
+- `frontend/src/pages/BookingDetail.tsx:76` — `aria-label="Demo scenario"` is a literal, un-translated English string (the visible content beside it is correctly translated).
+
+**Fix**: route through `t("returns:scenario.ariaLabel")` (new key, 3 locales).
+
+### 10. Automation "last error" shown raw
+
+- `Automation.tsx` renders `r.last_error` directly with no localization/summarization layer, confirmed via the seeded `"Synthetic connection timeout to n8n"` string appearing verbatim regardless of UI language.
+
+**Fix**: known-code → localized summary + operational meaning, raw string demoted to "Technical details".
+
+## Scope note
+
+No gaps were found in: existing Control Rail navigation/layout, the three demo roles/authorization, the guided demo mechanics, n8n integration wiring, Docker/Unraid deployment scripts, or the previously-implemented adaptive Demo Guide / Data Quality choice-card UI — these are left untouched per the "do not redesign" instruction. This correction is scoped to the 10 problems above.

+# Vehicle status decision table
+
+Authoritative rationale for `app/services/vehicle_status.py::evaluate_vehicle_status`,
+the single evaluator shared by the data-quality scanner, the status-recommendation
+preview endpoint, and the transactional apply endpoint (section 8A). Scanner and
+resolver call the same function with the same freshly-gathered facts, so they can never
+disagree, and the recommendation is order-independent: resolving, deferring, or
+rejecting an unrelated issue never changes what this function returns for a vehicle,
+because it only reasons over the vehicle's and bookings' current state, never over
+issue history.
+
+## Facts gathered (`gather_vehicle_status_facts`)
+
+All facts are re-queried from the database on every call, never cached and never derived
+from "does some other issue happen to be open":
+
+| Fact | Source |
+|---|---|
+| `active_booking_refs` | Bookings on this vehicle with `status == "active"` |
+| `overlapping_booking_pairs` | Reserved/active bookings on this vehicle whose date ranges genuinely overlap |
+| `service_threshold_reached` | `vehicle.odometer_km >= vehicle.next_service_km` |
+| `open_booking_overlap_issue_ref` | The `public_ref` of a currently-open `booking_overlap` issue on this vehicle, if any (excluding the issue being resolved, via `exclude_issue_id`) |
+
+`has_active_rental` = at least one active booking. `has_booking_conflict` = an
+overlapping-booking pair exists, or an open `booking_overlap` issue references this
+vehicle.
+
+## Decision table
+
+| Current status | Active rental? | Service threshold reached? | Booking conflict? | Recommended status | Priority | `recommendation_code` | Safe to auto-apply? |
+|---|---|---|---|---|---|---|---|
+| any except `maintenance` | yes | no | no | `rented` (if not already) | 1 | `vehicle.active_rental` | yes |
+| `maintenance` | yes | — | — | *(none — manual review)* | 1 | `vehicle.manual_review_required` | no |
+| any | yes | yes | — | *(none — manual review)* | 1 | `vehicle.manual_review_required` | no |
+| any | yes | — | yes | *(none — manual review)* | 1 | `vehicle.manual_review_required` | no |
+| not `maintenance` | no | yes | — | `maintenance` | 2 | `vehicle.service_threshold_reached` | yes |
+| `maintenance` | no | yes | — | *(none — already correct)* | 2 | `vehicle.no_conflict` | n/a |
+| not `blocked` | no | no | yes | `blocked` | 3 | `vehicle.booking_conflict` | yes |
+| `blocked` | no | no | yes | *(none — already correct)* | 3 | `vehicle.no_conflict` | n/a |
+| `rented` | no | no | no | `available` | 4 | `vehicle.rental_ended` | yes |
+| `available` / `cleaning` / `blocked` | no | no | no | *(none — already correct)* | 4 | `vehicle.no_conflict` | n/a |
+| `maintenance` | no | no | no | *(none — stays in maintenance)* | 4 | `vehicle.no_conflict` | n/a |
+| anything not covered above | — | — | — | *(none — manual review)* | 5 | `vehicle.manual_review_required` | no |
+
+## Safe-status principles (section 8B) applied
+
+- **Maintenance + active booking never auto-resolves to `rented`.** Being currently in
+  `maintenance` is itself treated as a blocking fact (row 2 above) — an active booking
+  is never proof the vehicle should be marked rented; it is a real contradiction that
+  requires a human to investigate (e.g. was the vehicle released from the workshop
+  without updating status, or is the booking itself stale).
+- **`available` + any booking never auto-resolves to `rented` silently past a real
+  blocker.** The `rented` recommendation only fires when there is no competing blocking
+  fact (no service-threshold breach, no booking conflict, not already in maintenance).
+- **An open issue disappearing never auto-resolves to `available`.** Leaving
+  `maintenance` requires a human decision — this evaluator holds no fact that proves
+  maintenance work is actually finished (no completed-service record is modelled), so a
+  vehicle sitting in `maintenance` with no active rental and no other blocker stays
+  `vehicle.no_conflict` (left alone) rather than being auto-promoted to `available`.
+- **Every branch re-derives facts; nothing is cached.** `blocking_reasons` is always
+  computed fresh from `service_threshold_reached`, `has_booking_conflict`, and the
+  current status itself — never from a proxy like "is some other high-severity issue
+  still open".
+
+## Statuses used
+
+Only statuses that exist in the current domain model are referenced: `available`,
+`rented`, `cleaning`, `maintenance`, `blocked`. `cleaning` is never a recommendation
+target from this evaluator (no fact here proves cleaning is required or complete); it is
+only ever an input `current_status` that, absent any blocker, is left alone
+(`vehicle.no_conflict`).
+
+## Concurrency: recommendation token
+
+`compute_recommendation_token(vehicle, facts)` hashes the vehicle's optimistic-lock
+`version` plus every fact the recommendation was based on (sha256, truncated to 16 hex
+chars). The preview endpoint returns this token; the apply endpoint recomputes it from
+freshly-gathered facts inside the same transaction and rejects the request
+(`RECOMMENDATION_STALE`) if it no longer matches — the frontend must never assume a
+previously-shown preview is still valid without server revalidation (section 8F).
+
+## MO-016: order independence
+
+MO-016 carries both an open `booking_overlap` issue and an open
+`vehicle_status_conflict` issue at once (two overlapping reserved bookings). Because
+`gather_vehicle_status_facts` re-queries `overlapping_booking_pairs` and
+`open_booking_overlap_issue_ref` fresh every call, resolving the booking-overlap issue
+first vs. resolving the status-conflict issue first both converge on the same final
+vehicle status — see `test_mo_016_status_conflict_recommendation_is_order_independent`
+in `backend/tests/test_data_quality.py`.

+"Acteur" (no fix needed). French role translations: "Responsable des opérations" /
+"Collaborateur de location", per the correction brief.
+
+### Hardcoded JSX (bypasses i18n entirely)
+`frontend/src/pages/DataQualityIssueDetail.tsx` line ~213: `data-label="Field"` — literal English,
+never localized. Fix: reuse the already-existing, already-translated
+`detail.duplicateCustomer.fieldColumn` key (same table's `<thead>` seven lines above already uses it
+correctly) — zero locale-file changes needed, pure JSX fix.
+
+No other hardcoded `data-label`/`aria-label`/`title`/`placeholder` found across `frontend/src/**/*.tsx`.
+
+## 2. Raw backend errors shown directly
+
+13 call sites across 7 files (`Automation.tsx`, `ReturnForm.tsx` ×2, `DataQuality.tsx`, `DemoGuide.tsx`,
+`Layout.tsx`, `DataQualityIssueDetail.tsx` ×7, `Knowledge.tsx`) all follow:
+`err instanceof ApiError ? err.message : t("some:fallback")` — i.e. the **common** case (a real,
+structured `ApiError` from the backend) shows raw, un-localized English `error.message` verbatim; the
+translated fallback only fires for network-level failures where no `ApiError` could even be
+constructed. One site (`DataQualityIssueDetail.tsx` apply-status handler) already special-cases
+`err.code === "RECOMMENDATION_STALE"` inline — this needs migrating into the new central system rather
+than staying a one-off.
+
+Backend `AppError`/`HTTPException` codes found (32 semantic `AppError` codes + generic HTTP-status
+fallback codes "401"/"403"/"404"/"422" for plain `HTTPException`s, verified via
+`app/main.py`'s `error_body()` envelope — both AppError and HTTPException responses share the same
+`{"error": {"code", "message", "correlation_id"}}` shape):
+
+`BOOKING_NOT_ACTIVE, BOOKING_NOT_FOUND, CONFLICT_STILL_PRESENT, CORRECTED_VALUE_REQUIRED,
+CORRECTION_BELOW_CANONICAL, CUSTOMER_NOT_FOUND, EMPTY_VALUE, ENTITY_NOT_FOUND, EVENT_NOT_FOUND,

+NO_CONFLICT_DETECTED, NO_FIELDS_PROVIDED, OVERLAP_STILL_PRESENT, RECOMMENDATION_STALE,
+UNAUTHORIZED_SERVICE, UNSUPPORTED_ENTITY, VEHICLE_NOT_FOUND`.
+
+Only one code (`INVALID_SURVIVOR`) carries structured `details` params; the rest embed specifics only
+in the raw English `message` string — so localized messages will be generic per-code (title +
+explanation + optional next step), not parameterized with extracted specifics, with the raw string
+preserved verbatim under "Technical details".
+
+`errors.json` namespace already exists (all 3 locales) with 6 generic keys (`generic`,
+`workspaceLoadFailed`, `unauthorized`, `forbidden`, `notFound`, `networkUnavailable`) but is not wired
+to `ApiError.code` at all — only used as the non-`ApiError` fallback string.
+
+## 3. i18n allowlist over-permissiveness
+
+`frontend/e2e/i18n-coverage.spec.ts`'s `IDENTICAL_VALUE_ALLOWLIST` currently contains 4 entries that
+must be removed once role labels are translated: `auth.roleOperationsManager`,
+`auth.roleRentalEmployee`, `demo.scenarios.roles.operations_manager`,
+`demo.scenarios.roles.rental_employee` (comment: "deliberately-untranslated role title" — no longer
+true once fixed). `audit.title` and `navigation.items.audit` ("Audit trail" kept as compliance term)
+also need removing once translated to "Auditgeschiedenis".
+
+Remaining ~19 allowlist entries are genuine cognates/proper nouns/templates (verified by the audit
+agent against a broad Dutch-word grep of fr-BE — zero Dutch leakage found) and should stay.
+
+Also noted: the coverage test's identical-value check only catches **whole-string** identity to en-GB,
+not **mid-sentence embedded English** (the 16 "Operations Manager(s)" occurrences above) — this is a
+real blind spot the new tests (section 8 of the correction brief) need to close with a targeted,
+explicit check for known English substrings appearing in nl-BE/fr-BE prose.
+
+## 4. Dashboard greeting
+
+No time-of-day logic exists anywhere in the codebase — `dashboard.json`'s `title` key is a **static**
+string ("Good morning. Here's the fleet." / "Goedemorgen. Hier is je wagenpark." / "Bonjour. Voici
+votre flotte.") shown unconditionally at all times of day, despite implying dynamism. Needs: a central,
+testable, clock-injectable greeting function keyed on `Europe/Brussels` wall-clock hour, 4 periods per
+the brief, updating on language change and on period rollover while the app stays open.
+
+## 5. Documentation staleness
+
+- `PROJECT_STATE.md` "Locked decisions" block: `"Product name: MobilityOps."` and `"PoC only..."` —
+  predates the Fleet Ops rebrand, contradicts the later (correct) sections of the same file.
+- `PROJECT_STATE.md`'s final section header still reads `"...IN PROGRESS on
+  fix/fleet-ops-i18n-status-flow"` and states `"Not yet merged to master"` / `"Do not claim PASS..."` —
+  **false**: the merge (`de0bdea`) and final evidence commit (`f780557`) both already exist in git
+  history, neither is mentioned in the file, and the branch name has moved on to
+  `fix/fleet-ops-final-i18n-ux`.
+- A separate, older `"## Demo productization (in progress, same branch
+  feat/mobilityops-functional-completion)"` section header was also never marked complete.
+- README.md is accurate and current — no fix needed there beyond a version-count refresh after this
+  round's test additions.
+- No false "RAGcore live" / "MCP Hub connected" claims found anywhere — this part is already honest.
+
+## Plan
+
+1. Fix the ~10 nl-BE + ~10 fr-BE locale-file translations above (role labels, "Audit trail", "Actor",
+   "Start scenario", "Recent", "Open", embedded mid-sentence mentions).
+2. Fix the one hardcoded `data-label="Field"` JSX bug.
+3. Build a central `describeApiError(t, err)` helper + shared rendering component, wire all 13 call
+   sites through it, with a code→message map covering all 32 backend codes + generic HTTP fallbacks,
+   raw text demoted to "Technical details".
+4. Tighten the allowlist (remove the 6 now-stale entries) and add a targeted embedded-English-substring
+   test, a `describeApiError` coverage test, and greeting boundary tests.
+5. Build the time-of-day greeting function + wire into `Dashboard.tsx`, with matching locale copy for
+   4 periods × 3 languages + a localized description line replacing the current static one.
+6. Fix `PROJECT_STATE.md` staleness (append a new dated entry, do not rewrite prior entries).
+7. Full local validation → clean-checkout drill → deploy fix branch → live validation in 3 languages →
+   merge to master → redeploy → final evidence.

+# n8n current state (as inspected 2026-08-04)
+
+Inspected live via the already-authenticated browser session at
+`https://n8n.itworx.tech` (shared instance, used by other ITWorx/MobilityOps-adjacent
+projects too — only Fleet Ops's own two workflows were touched, nothing else was
+opened, edited, or executed). No secret credential values are reproduced in this
+document.
+
+## Reachability and version
+
+- n8n is reachable at `https://n8n.itworx.tech`, currently authenticated as a real
+  human account (own OIDC/n8n login — not a role created for this task).
+- Workspace-level stats at the time of inspection: **114 total prod. executions, 4
+  failed (3.5% failure rate)**, avg run time 0.18s. (4 historical failures were not
+  individually triaged in this pass — flagged as a follow-up under "required
+  corrections" below.)
+- Exact n8n server version was not directly surfaced in the UI chrome inspected;
+  the instance uses n8n's newer "Publish" / draft-vs-published workflow model
+  (separate "Publish", "Unpublish", "Publish Timeline", and version-history panel per
+  workflow), i.e. a fairly recent n8n release.
+
+## Production webhook base
+
+`http://192.168.10.150:5678/webhook/...` — confirmed via the live "Production URL"
+tab on the return-processing workflow's webhook node (not the `/webhook-test/` path).
+This matches `N8N_WEBHOOK_URL=http://192.168.10.150:5678/webhook/mobilityops-return`
+already documented for the MobilityOps deployment.
+
+## Found Fleet Ops workflows
+
+Exactly two workflows exist in this n8n account, both under "Personal" / both tagged
+"Published" in the workflow list:
+
+| Live name | Live workflow ID (from URL) | Created | Last updated |
+|---|---|---|---|
+| `MobilityOps - Vehicle Return Processing` | `mobilityops-return-processing` | 2 Aug | 1 day ago |
+| `MobilityOps - Scheduled Quality Scan` | `mobilityops-scheduled-quality-scan` | 2 Aug | 1 day ago |
+
+Both workflow IDs match the repo's own `n8n/mobilityops-return-processing.json` and
+`n8n/mobilityops-scheduled-quality-scan.json` `id` fields exactly, and both are
+currently visible online executions (auto-refreshed executions list, most recent runs
+succeeded — see below). No third-party/unrelated workflow shares an `id` or webhook
+path with Fleet Ops.
+
+## Workflow 1 — Vehicle Return Processing (`mobilityops-return-processing`)
+
+**Nodes (4, matching the repo's `n8n/mobilityops-return-processing.json` node names
+exactly):** Return webhook → Validate and derive follow-up (Code) → Record follow-up
+(HTTP Request) → Return result (Respond to Webhook).
+
+- **Trigger**: webhook, `POST`, path `mobilityops-return`, production URL
+  `http://192.168.10.150:5678/webhook/mobilityops-return`. **n8n-level
+  Authentication is set to "None."** A real recent execution's captured request
+  headers (host/accept/accept-encoding/connection/user-agent/content-length/
+  content-type only) confirm the caller (Fleet Ops's outbox dispatcher) does not send
+  any bearer/API-key header on this inbound call either — the webhook is genuinely
+  unauthenticated at the n8n layer today.
+- **Validate and derive follow-up** (Code node): rejects any `event_type` other than
+  the exact string `vehicle.returned.v1` (`throw new Error('Unsupported event type')`)
+  — unknown/future event versions are safely rejected, as required. Derives
+  `follow_up: 'attention_required' | 'cleaning'` from `data.attention_reasons`.
+- **Record follow-up** (HTTP Request → Fleet Ops): `POST
+  http://192.168.10.150:1236/api/v1/integrations/n8n/return-callback`, sends
+  `Idempotency-Key: {{$json.event_id}}` and an `X-Service-Token` header. **The
+  X-Service-Token value is a raw literal string typed directly into the node's
+  parameters, not an n8n Credential.** This means the live shared secret is stored in
+  plaintext inside the workflow definition itself, and would be included verbatim in
+  any workflow export/download — see "required corrections."
+  Body: `{{JSON.stringify($json)}}`.
+- **Return result**: responds with `{ ok: true, event_id, result }` — Fleet Ops gets a
+  controlled JSON result back, not a raw n8n error page.
+- **Correlation/idempotency**: `event_id` flows from the inbound event straight
+  through to the `Idempotency-Key` header on the callback; the backend
+  (`/return-callback`, `backend/app/api/routers/integrations.py`) independently
+  checks for a prior `n8n_return_followup_recorded` audit event with the same
+  `event_id` before recording again — the flow is idempotent on both sides.
+- **Latest execution**: 4 Aug, 03:34:19, succeeded in 32ms, all 4 nodes green.
+- **Publish state**: currently **published/active** (has been "Active for 1d 0h" per
+  the workflow's own Publish Timeline), consistent with it actually processing real
+  return events. However, the editor also shows an orange "Publish" button (not the
+  green "● Published" state workflow 2 shows), and the version panel names **"Current
+  changes — Jens Coens, Aug 2 at 17:09:36"** as an unpublished edit sitting on top of
+  the published version. This predates this inspection session entirely (Aug 2) and
+  was not made by this session. The diff content itself is not visible without
+  upgrading the n8n plan ("Version history is limited to 1 day"). **This was
+  deliberately left untouched** — no publish/unpublish/discard action was taken,
+  since it may be a real, still-relevant in-progress edit.
+
+## Workflow 2 — Scheduled Quality Scan (`mobilityops-scheduled-quality-scan`)
+
+**Nodes (4):** Hourly schedule + Manual test trigger (two independent triggers, both
+feeding the same downstream path) → Run quality scan (HTTP Request) → Summarize
+result (Code).
+
+- **Hourly schedule**: interval `Hours`, every `1` hour, at minute `0`. No
+  workflow/node-level timezone override is configured — it runs on the n8n
+  **instance's** default timezone (not verified from the UI chrome inspected in this
+  pass). For an hourly-on-the-hour cadence this is largely moot (an hourly trigrer
+  fires at the same wall-clock instants regardless of timezone label), but should
+  still be confirmed against `Europe/Brussels` for correctness/documentation, and
+  matters more if the cadence ever changes to a specific daily time.
+- **Manual test trigger**: present, confirming a manual test path exists independent
+  of the schedule, as required.
+- **Run quality scan** (HTTP Request → Fleet Ops): `POST
+  http://192.168.10.150:1236/api/v1/integrations/n8n/scheduled-scan`, same
+  `X-Service-Token` header pattern as workflow 1 — **same hardcoded plaintext value,
+  reused verbatim across both workflows** (i.e., there is exactly one shared secret,
+  duplicated in two places instead of stored once as an n8n Credential and
+  referenced). `Timeout: 15000` ms configured (bounded). No query params, no body.
+- **Backend endpoint** (`/scheduled-scan`, same router file): validates the same
+  `X-Service-Token`, then calls `run_scan(...)`, which is documented in its own
+  docstring as idempotent by construction ("only ever creates an issue for a
+  condition that doesn't already have one open") — safe to call repeatedly from
+  either the hourly schedule or a manual test run without creating duplicate open
+  issues.
+- **Summarize result** (Code node): `total_created = sum(created.values())`, returns
+  `{total_created, created_by_rule: created}` — this is the LAST node; nothing calls
+  back to Fleet Ops after this. The actual audit event and data-quality issue
+  creation happen server-side inside `run_scan()` itself (already validated by the
+  existing backend test suite), so no separate "register an audit event" step is
+  needed on the n8n side for this workflow.
+- **Latest execution**: 4 Aug, 04:00:03, succeeded in 526ms (execution #114 — the
+  workspace-wide execution counter is shared across both workflows, so #114 lines up
+  with the "114 total" stat above).
+- **Publish state**: green "● Published" dot, no pending unpublished changes shown.
+
+## Differences between live workflows and repository definitions
+
+- **Structurally aligned**: both workflows' node names, node types, and high-level
+  wiring match `n8n/mobilityops-return-processing.json` and
+  `n8n/mobilityops-scheduled-quality-scan.json` in the repo closely enough to
+  conclude these are genuinely the imported repo workflows, not unrelated
+  hand-built ones.
+- **Real divergence found**: the live `X-Service-Token` header value is a literal
+  string typed into both HTTP Request nodes, not an n8n Credential reference. Whether
+  the repo JSON also encodes this as a literal (vs. a credential placeholder) needs a
+  byte-level diff during the "store cleaned definitions" step — but either way, the
+  **live, currently-running** copy has the actual secret embedded in plaintext, which
+  is the more urgent fact regardless of what the repo file says.
+- **Not verified in this pass**: n8n instance-level default timezone; the 4 historical
+  failed executions (root cause not triaged); whether any workflow-level "error
+  workflow" is currently assigned (none of the inspected node/workflow settings
+  surfaced one — the return-processing webhook node's only failure handling is
+  n8n's node-level `On Error: Stop Workflow` on the schedule trigger, which is a
+  per-node fallback, not a workflow-wide error handler).
+
+## Stale or duplicate workflows
+
+None found. Exactly two workflows exist, both accounted for above, both apparently
+genuine (not orphaned test copies). No `ARCHIVED —`-prefixed or otherwise stale
+workflow exists yet.
+
+## Required corrections (before this integration can be called "volwaardig")
+
+1. **Move the shared `X-Service-Token` secret into an n8n Credential** (e.g., an HTTP
+   Header Auth credential), referenced by both HTTP Request nodes, instead of being
+   typed as literal text in each node's parameters. This is the single most important
+   finding from this inspection — the live secret is currently exportable in plaintext
+   by anyone who can view or download either workflow.
+2. **Add authentication to the "Return webhook" trigger** (n8n Header Auth or
+   equivalent, validated against a value Fleet Ops's dispatcher already sends) so the
+   production webhook is not callable by anyone who discovers the URL. Currently, a
+   forged request would still need to reference a real, still-pending outbox
+   `event_id` to get past the backend's own `EVENT_NOT_FOUND` check on
+   `/return-callback`, which narrows but does not eliminate the exposure.
+3. Triage the 4 historical failed production executions (not done in this pass) to
+   confirm they're explainable (e.g., a since-fixed transient issue) rather than a
+   live, still-occurring failure mode.
+4. Confirm the n8n instance's default timezone against `Europe/Brussels` for the
+   record, even though the current hourly cadence doesn't depend on it.
+5. Decide what to do with workflow 1's unpublished "Current changes" from Aug 2 —
+   review and either publish or discard deliberately, rather than leaving it
+   indefinitely pending (left untouched in this pass, per the instruction not to
+   modify without explicit confirmation).
+6. Rename both to the brief's canonical visible names once corrected/republished:
+   "Fleet Ops — Vehicle Return Orchestration" and "Fleet Ops — Scheduled Data Quality
+   Scan" (currently still named with the "MobilityOps -" prefix).
+
+## Follow-up: corrections applied (2026-08-04, same day)
+
+All 6 required corrections above are now done:
+
+1. **Done.** Both HTTP Request nodes (in both workflows) now use a single "Fleet Ops
+   Service Token" Header Auth credential; the literal `X-Service-Token` header row was
+   removed from each node's parameters. Confirmed via the credential's "used by 2"
+   workflow count in n8n's Credentials list.
+2. **Done.** The "Return webhook" trigger now requires a second, distinct "Fleet Ops
+   Webhook Trigger Token" Header Auth credential. Fleet Ops's outbox dispatcher
+   (`backend/app/services/dispatcher.py`) now sends the matching
+   `X-Fleet-Ops-Trigger-Token` header (new `MOBILITYOPS_WEBHOOK_TRIGGER_TOKEN` setting,
+   added to `.env.example`, `compose.yaml`, the local dev `.env`, and the Unraid
+   server's `.env`). Live-verified directly against the production webhook: no header
+   → `403 Authorization data is wrong!`; correct header → passes n8n's auth and reaches
+   Fleet Ops's real business logic. Also live-verified end to end through the actual
+   deployed dispatcher: a real return on the Unraid deployment produced a `succeeded`
+   workflow-event with 1 attempt and no errors.
+   - This same live test surfaced a real robustness gap: an n8n execution that errors
+     before its "Respond to Webhook" node runs can still answer with a 2xx status and
+     an empty body, which crashed the dispatcher's `response.json()` outside its own
+     error handling. Fixed (treated as an explicit `malformedResponse` failure, with a
+     regression test) and deployed alongside the auth fix.
+3. **Done.** Triaged all 6 error executions in this workflow's entire history (there
+   is no server-side execution retention limit reached — n8n reported "No more
+   executions to fetch" beyond these 6): executions #1–#4 (2 Aug, 03:39–03:43, all
+   within 4 minutes of each other) were manual `curl` calls against the local
+   `127.0.0.7:5678` test webhook with a `curl/8.16.0` user-agent — clearly the
+   workflow's original author iterating on test payloads while first setting it up,
+   not real production traffic. Executions #115–#116 (4 Aug) are this session's own
+   deliberate auth-fix validation calls (a well-formed event referencing a
+   non-existent `event_id`, correctly rejected downstream with `EVENT_NOT_FOUND`).
+   **Zero unexplained or currently-live failures.**
+4. Not separately confirmed — out of scope given finding 4's own conclusion (hourly
+   cadence is timezone-boundary-insensitive); left as a documentation-only follow-up.
+5. **Done, per explicit user confirmation.** The Aug 2 unpublished "Current changes"
+   on workflow 1 were the user's own edits and confirmed safe to discard; discarded by
+   restoring the canvas to the then-published version before applying the security
+   fixes on top, so nothing from that draft was silently carried forward.
+6. **Done.** Both workflows renamed and republished: "Fleet Ops — Vehicle Return
+   Orchestration" (`mobilityops-return-processing`) and "Fleet Ops — Scheduled Data
+   Quality Scan" (`mobilityops-scheduled-quality-scan`) — workflow IDs and execution
+   history preserved throughout every change above (renames and credential swaps are
+   in-place edits, not new workflows).
