The 4a/4b split held; five P1s against rev 6's own content, all real,
all reproduced. Four share a root: rev 6 verified its external facts and
under-verified its internal ones.
1. Stage 4a's declared footprint excluded the tests its own acceptance
required. 46a-46e cannot live in tests/auto_pair_acceptance.rs,
which criterion 46 requires byte-identical. Footprint now names
tests/typed_edit_chain_acceptance.rs and gates on it.
2. Pending abbreviation state had the wrong owner. pmacs is
multi-frontend: EditorCore.views is per-FrontendId with its own
active window, take_typed_edit is already frontend-keyed, and
buffer.after-switch fires with no arguments — so a buffer-keyed
clear-on-switch lets any frontend discard another's pending
abbreviation. Now keyed (frontend, buffer) with a window check,
frontend-scoped clearing, a frontend.detached purge, and acceptance
45i, which the buffer-keyed design passes every other criterion
without.
3. The shortest-match rule was missing its tie-break: upstream keeps
declaration order among equal-length shortest keys, and 101 prefixes
have equal-shortest candidates resolving to different symbols (f
picks f< over f>). A pairs-iterated Lua map cannot express this, so
the vendored artifact is now an ordered sequence and resolution sorts
by (#key, source rank). Rev 6 missed this because it declared the
package ships no README after a 404 on the package root, with the
directory listing showing src/README.md already in hand — a 404 on a
guessed path is not evidence of absence, and the README states the
rule in one sentence.
4. The generator's rejection rule rejected the current table: \ is a key
and " begins eleven, while acceptance 45d requires \ to work.
Replaced with canonical lossless escaping; aborts only on duplicate
keys, invalid UTF-8, and a failed self-round-trip. 45g no longer
claims to diff against abbreviations.json, which is not shipped.
5. Durable and volatile state were not reconciled. agent-handoff.md
anchored main at d152120 with neither #167 nor #170 and no Lean arc
bullet at all; active-work.md kept 407 lines of merged Stage 1/2/3a/3b
history against its own instruction to prune merged entries, under a
stale snapshot date. Durable facts moved to the handoff; the ledger
keeps only the unlanded Stage 4 lane.
Also corrected: 119 multi-codepoint symbols (26 with $CURSOR), not 93;
three backslash values, not two; Q#LN22 now states the terminating-\
reprocess rule acceptance 45d depended on; acceptance 38 says the
terminator is retained, so undo restores "\alpha " with its space;
coherence cites golden-journey step 5, not step 4; and the
config-registry prior art points at Q#LN22.
