Phase 1.0DD: minimal launcher source-prerequisite audit
Status: LAUNCH_EXPORT_NAMES_PRESENT_ABI_AND_FW960_TITLE_CONTRACT_BLOCKED
This is an offline read-only audit of the pinned public SDK and official shsrv v0.7 source. It creates no target source, launcher artifact, transport or device action.
The SDK stubs contain export names for foreground-user lookup, running-BigApp
lookup and application launch. They do not contain C declarations, parameter
semantics or the launch-context structure layout. All declarations used by
the candidate—including app_launch_ctx_t—are local to the same shsrv v0.7
source lineage. A symbol name is not an ABI, so this is insufficient evidence
for new Chimera target code.
The v0.7 source hard-codes PPSA01659 and labels it VideoPlayer/WebApp. That
proves upstream intent only. It does not prove that the title exists, launches
or supplies VideoOut ownership on firmware 9.60. No currently reviewed,
nonmutating observer can establish that premise.
A bounded public search on 2026-07-30 targeted the exact function and
structure names. It found a recent
sonicloader
candidate, but that project's
own commit description says the context changes were ported from a supplied
reference snippet. The same project includes persistent/autolaunch scope. It
is therefore derivative evidence, not an independent ABI source, and is not a
permitted Chimera dependency. The search found no qualifying independent
header or firmware-9.60 title contract; this is a bounded result, not a claim
of global absence.
AF–AU already model bounded ELF admission, mapping rollback, copy/credential restoration, worker supervision, result records and deadline-driven FD ownership. Those host models do not supply the missing ABI or firmware runtime evidence. DC therefore cannot yet bind a launcher hash.
Target implementation remains blocked until independent public source binds the three function signatures and launch-context layout, firmware-9.60 title presence can be established fail-closed, and one target composition proves absolute deadlines, restoration and the live result channel. Guessing the ABI, copying v0.7 declarations or invoking hbldr is explicitly excluded.
