The provider sandbox never ran. bubblewrap 0.9.0 stops parsing an `--args`
file at the first non-option and never hands the remainder back, so the
command written into that file was silently dropped: bwrap printed its usage
text, exited 1, and the provider produced no evidence at all. The options
still travel in the args file — that is what keeps host paths and credentials
out of `/proc/<pid>/cmdline` — but the command now rides on real argv, and
`encodeProviderBwrapInput` refuses a `--` so the drop cannot come back.
The scope wrapper then could not exit. It read the supervisor's liveness pipe
through `fs`, which runs a blocking `read(2)` on a threadpool thread; the
supervisor holds that pipe open for the scope's whole life, so the read never
returned and closing the descriptor did not interrupt it. Once bubblewrap
finished the wrapper deadlocked in `process.exit`, the scope outlived the
provider, and a completed run was reported as a timeout kill. The channel is
now read through the event loop, so teardown is observable and terminal.
Creation modes were left to the ambient umask. `mkdir(mode)` and `open(mode)`
are requests the kernel subtracts the umask from, so a runner exporting a
restrictive umask produced directories it could not enter and handed `tar` a
file it could not re-open. Private modes are pinned instead of inherited.
Promotion cleanup deleted before it checked. Removals run through a pinned
descriptor, so a leaf substituted after validation had this promotion's exact
five destroyed first and the substitution reported afterwards, leaving a
half-emptied directory a retry could not tell from a completed one. The name
is re-bound to the inode before anything is removed, so the failure is total.
Separately, release coherence proved the artifacts agreed with each other but
never that they belonged where they were going: a build whose runtime document
said `APP_ENV: local`, `AUTH_MODE: demo` and a loopback API is coherent with
itself and passed every gate. `public/` is copied verbatim into `dist/`, so
that local document shipped with every build regardless of what the build was
for. Runtime configuration now comes from a declared profile, and FE-GATE-027
refuses to admit an artifact to an environment it does not match — including
refusing an undeclared destination, so nothing is admitted by omission.
`REQUEST_TIMEOUT_MS` and `VITE_ROUTER_BASE_PATH` were validated and then
dropped: the V3 executor ran every operation on its contract's own deadline,
and Vite emitted root-absolute assets for a sub-path deployment. The timeout is
now a ceiling that may tighten a contract but never loosen one, and one base
path feeds the router, the Service Worker scope and the asset base together.

The ledger declared "All 38 are now FIXED" while six of those rows were
reproducibly partial. A summary sentence is cheap and a reviewer reads it
as evidence, so the claim is now derived from a machine-readable record:
`docs/operations/adapter-remediation-dispositions.json` carries each
finding's disposition and the test paths that hold it, and
`check:remediation-ledger` joins that file to the prose, verifies every
evidence path exists, and refuses a blanket closure sentence while any row
is still open.
The shared-abort gate had the same weakness in miniature: it passed when
at least one production file imported the primitive, so an unrelated
import satisfied it while Image and Resumable kept their own diverging
copies. It now requires the four named consumers to resolve their import
to the primitive itself, and prints the exact importer set rather than a
count.
`check:optional-recipes:source` was already failing before this work
(52,078 against a 52,000 budget) and the correctness code above pushed it
further. Duplicate abort mechanics were consolidated first — Image and
Resumable onto the shared primitive, four decoders onto one snapshot
helper — and the remainder is code the review asked for, so the budget is
reset to 54,600 against a measured 53,810 with that reasoning recorded,
rather than the failure being carried forward as if it were green.
