Docs only. No `src/`, no `pmacs-gpu/`, no 1a implementation.
**The recovery procedure was RE-RUN, not SHA-swapped, and that is what
licenses the rest of this commit.** Every documented step, from an empty
directory, on git 2.55.0: clone the canonical URL (which names it
`origin`, and `git remote get-url githubsucks` errors with `No such
remote`, exactly as the section anticipates); add the alias; fetch;
`git log -1 --oneline githubsucks/main` -> `d038f71`; confirm BOTH the
old floor `9a26ac8` and the new `d038f71` are ancestors, so advancing
the floor is valid rather than merely plausible; recover with the
three-argument `git worktree add <path> -b <local> githubsucks/<branch>`
form and confirm the upstream is actually set. The documented TRAP was
reproduced too: the two-argument form succeeds and leaves
`## HEAD (no branch)`, so that correction still holds on 2.55.0.
**This discharges a debt rather than inheriting one.** The previous
absorption advanced the base to `e67ad07` WITHOUT re-running the
procedure and recorded that as an outstanding obligation. It is settled
here, by the run above.
Canonical base, recovery floor, the `git log` threshold and the
last-exercised record all move to `d038f71` together --- a floor that
accepts an older commit than the base it declares passes on a tree the
rest of the file does not describe.
**The GUI lane is REWRITTEN, not removed.** Rule 4 removes a lane when
its ARC is done; the arc is Stage 1 as a whole and **five slices
remain**. The lane now records 1-pre as merged, names 1a as next and
NOT STARTED, and keeps the fact that 1a (v24 `TextInput`) and 1e (v25
`OpenTarget`) are the two protocol-bearing slices and are serialized.
Open-PR and branch-recovery wording for 1-pre is gone --- a lane that
still says "recover with `git checkout`" for a merged branch is how a
reader ends up on a stale tip.
The handoff anchor absorbs both merges, and §1 gains the arc bullet the
anchor promises. Its durable facts are the ones that will bind future
slices rather than the diff: a route carries the DECISION and only the
body gives the EFFECT; a harness that re-implements what it tests
witnesses its own copy; winit's `KeyEvent` is non-constructible outside
winit and this will bind every GUI input slice; the sentinel is the
success condition and the timeout only an error ceiling; four test
defects that were all one shape --- witnessing an absence the harness
had manufactured; and `cargo metadata`, not intuition, decides which CI
job runs a member's unit tests.
**One judgement beyond the stated scope, flagged rather than slipped
in.** §1a's board had no GUI-arc row at all, which would have
contradicted the anchor two sections above it. A row is added at the
position `COHERENCE.md` §20 Q#GA5 gives it --- after Priority 1, running
alongside P2-P5, interacting only at the P2 start gate --- and the P2
row now names that gate. The section's own dateline is corrected in the
same breath: the table was written 2026-08-01 and claimed zero open PRs,
so it now says which row is current and which are as-of that date.
