Completes Journey Stage 1a: the `commit_to` acceptance suite (framing
§6 N4, N6, N6b, N6c, P1, P2, P3) plus the documentation updates
COHERENCE §25 requires the PR to carry.
Bite-testing the new pins found a real gap. Deleting the
`ScopedFrontend` arm from `acting_frontend` left N4 green, because
`ScopedFrontend::enter` also swaps `core.active_frontend` and the
ambient fallback then answers correctly on its own. The arm is
load-bearing in exactly one case — a commit reached from inside an
interactive command, where the origin sits between the override and the
ambient value — and nothing pinned it. N4b is added, driven through
`dispatch_key` because that is the only thing that establishes an
interactive origin, and the mutation now bites it.
Two smaller corrections found the same way:
* `commit_to`'s forged-destination message was unreachable. Typed as
`AnyUserData`, mlua rejected a table during argument conversion, so a
caller got "error converting Lua table to userdata" — true, but naming
neither the rule nor the remedy. The parameter is now `mlua::Value`
and the pointed message fires.
* P1 and P2 also fail on full revert, since `commit_to` does not exist
on the pre-image, so §6.0's "legitimately green on the pre-image" does
not describe them. They stay in the P list because their
discriminating falsifier is the named mutation — a revert-only check
cannot distinguish "validates" from "validates in time" — and each pin
now says so at its own site rather than being silently mislabelled.
Bite results, each run against the whole suite:
scope stops swapping `core.active_frontend` -> N6a, P3 fail; nothing else
preflight moved after the callback -> P1, P2 fail; nothing else
drop the `ScopedFrontend` arm -> N4b fails; nothing else
Docs: COHERENCE §2 grade + step-3 verdict row, §20 Priority 1 and the
arc list; the GPU initial-target framing's Q#GT6 and acceptance 10,
whose directory case this stage deliberately supersedes; handoff §1;
the active-work ledger; framing rev 7.

Integrate folding Stage 2 and its landed-state documentation with the
protocol-v20 GPU initial-target branch. Preserve per-session fold projection
selection in the target bootstrap transaction and retain v19 compatibility
coverage after the later protocol bump.
Shut down bootstrap sockets on every dispatcher-side failure and reject
frontend events whose session state was never installed. This prevents a
lingering failed client from reaching absent render/size state.
Track target-side CRDT upgrades independently from load/create status so a
deduplicated hidden buffer is published to every existing grid replica. Add
real-daemon regressions for both failure containment and replica publication.
Keep foreign BufferSnapshot publications out of existing semantic GPU
sessions while retaining grid-replica coherence. Treat dead peer writes as
peer-local failures, restore active-frontend cleanup, deterministic probe
readiness, GPU logging, shared tilde expansion, and accurate docs.
Add focused publication and cleanup coverage and record the two-window
Wayland/Vulkan smoke plus the complete post-review gate results.
Update the framing, durable handoff, and active-work ledger after integrating
current canonical main and completing the required gates and real GPU smoke.
Add protocol-v20 semantic bootstrap and readiness result framing so
`pmacs --gpu FILE` opens the requested path before the GPU window becomes
ready. Keep target identity scoped to the authenticated frontend, preserve
legacy/no-target attach behavior, and publish fresh buffers coherently to
existing replicas.
Carry Unix path bytes and launcher cwd through the root broker, resolve paths
lexically in the daemon, reuse or create buffers without ambient-view state,
and preserve the managed daemon lifecycle from #141. Add focused parser,
wire, lifecycle, hook, isolation, and real-connector acceptance coverage.
Pin launcher-owned tilde expansion, require same-buffer dedup hooks, fail
closed when hooks kill the target, and document stderr feedback during the
pre-window bootstrap wait. Record the observed protocol-version echo and
non-Unicode argv panic.
