+# Phase 1.0AC: offline dormant adapter
+
+Status: `OFFLINE_DORMANT_FAKE_SYSCALL_ADAPTER_COMPLETE_LIVE_ADAPTER_BLOCKED`
+
+Date: 2026-07-22
+
+Chimera GFX is a graphics/homebrew project. This phase adds host-side test
+infrastructure for a possible future one-shot launcher observation; it is not
+a security feature and it changes no RetroArch, SDL, VideoOut or target code.
+
+## Closed capability boundary
+
+`phase10ac_dormant_adapter.py` composes the Phase-1.0Z passive batch parser
+with an exact built-in fake syscall facade. The facade consumes caller-created
+synthetic outcomes. It cannot accept a live implementation and stores no
+target. The module imports no socket, selector, DNS, real clock or filesystem
+output interface and exposes no CLI.
+
+The adapter requires a precommitted-receipt marker before the first synthetic
+create step. It then models:
+
+1. one create and immediate nonblocking setup;
+2. immediate or pending connect completion;
+3. readiness plus `SO_ERROR == 0` for a pending result;
+4. an explicit partial-write loop for exactly one Phase-1.0Z batch;
+5. bounded read readiness and at most 65,536 supplied bytes;
+6. deadline-only result sealing;
+7. one local close on success or any failure after successful create.
+
+Timeout and interrupted-wait events stay inside the same synthetic attempt.
+They never create a retry, reconnect or resume. When readiness coincides with
+the deadline, the deadline wins and no subsequent fake read or write occurs.
+EOF, zero progress, excess progress, malformed data and cleanup failure all
+invalidate the run.
+
+## Evidence boundary
+
+The 32 host tests cover immediate and pending connect paths, partial writes,
+interrupted and timeout waits, exact deadline races, EOF, receive limits,
+malformed results, cleanup and closed fake types. They prove only the Python
+model's behavior. They do not prove:
+
+- a deployed shsrv identity or port-2323 behavior;
+- Windows scheduler or real socket timing;
+- a live connect, send, receive or remote-process cleanup;
+- firmware-9.60 behavior;
+- RetroArch launch context, SDL, VideoOut or rendering.
+
+## Decision
+
+The dormant fake-syscall adapter is complete. A live adapter remains blocked
+and absent. The next permissible step is an offline-only Phase 1.0AD design
+for numeric target validation and an inactive activation record. That phase
+must still contain no socket creation, connection, device request or enabled
+authorization.
