Levi Neuwirth aea5097890 docs(framing): revision 3 of the resource-op delete guard
Review round 2 confirmed everything central from round 1 as fixed and
raised four P1s. All four accepted; both requested sweeps run. Rebased
onto `7586905`.

P1-1, the ownership boundary was stale. Revision 2 described PR #171 as
"OPEN, STALE, 153 commits behind, under re-scout" claiming the rename
side only. Re-checked directly: #171 is at revision 7, `fd7ae37`,
merge-base `ad41cf1`, zero commits behind, and its revision 6 had
assigned rename AND delete to Stage 2a with the opposite policy --- file
deleted, modified buffer kept alive and orphaned, that orphaning named
as accepted residue. Two lanes, opposite answers, same event. The
settled split is now carried verbatim in the framing and the ledger, and
#171 revision 7 has adopted it from its side.

P1-2, the LSP failure-handling claim was wrong. The spec does not assign
`Abort` to resource-op-bearing edits. Recovery is described by the
client's advertised `workspace.workspaceEdit.failureHandling`; `Abort`
is one of four strategies, `Transactional` covers all operations, `Undo`
attempts rollback, and only `TextOnlyTransactional` degrades to abort
when resource changes are present. pmacs advertises none, so the spec
assigns pmacs no strategy at all. Section 1.7 and B2 now rest on
verified repository behaviour --- the reproduced partial batch --- not
on borrowed protocol authority.

P1-3, Q#RD7 had no implementable seam. Three gaps confirmed by reading:
`_parse_workspace_edit` is called one line above `apply_workspace_edit`
and is fallible, so the proposed wrap left "always answers" untrue;
`append_to_errors_buffer` is private and a Lua preflight rejection never
reaches Rust, so the promised logging was not implementable from where
it was promised; and acceptance 13 tested the response but not the
trace. Q#RD7 is rewritten around one seam at the server-request
boundary, and of the two options offered this revision picks wrapping
parse-plus-apply rather than narrowing the claim.

P1-4, clean duplicate reconciliation is now Q#RD10: validate every
match, reconcile today's first exact-path match only. Widening would
enlarge the parked lifecycle defect Q#RD5 exists to contain; the
surviving clean duplicate is named as residue handed to #171.

External-claim sweep. Every non-repo claim is now listed in a new
section 1.15 with its evidence. One was a paraphrase standing in for a
quote: "in Emacs `kill-buffer` on a modified file-visiting buffer
prompts". It is true, but the gate is `INTERACTIVE`, defined as
`(NILP (Vexecuting_kbd_macro) && !noninteractive)` --- keyboard present,
not `call-interactively` --- so eglot's programmatic kill does prompt in
a normal session and does not in batch or during a keyboard macro. The
revision 2 sentence was right for a reason it never established and
false in two environments it never considered.

Cross-lane sweep. Q#RD8 said mode (d) needs its own lane; it has one now
--- #171's `reconcile_delete` composes both removal phases. Q#RD6 claims
the shared walk query explicitly so the duplicate resolves in one
direction. And `pmacs.fs.remove`, guarded by neither lane and verified
to have zero production callers, is named as explicitly out of scope
with its owner rather than left to read as covered.

Still PROPOSED. No runtime code. Implementation begins only after
explicit user approval.

Levi Neuwirth e1e9b44154 docs(framing): revision 2 of the resource-op delete guard
Review round 1 approved the refusal strategy in principle and rejected
revision 1 as written. Six blocking points, all accepted, plus three
further overclaims found by the requested sweep. Q#RD1 and Q#RD5 are
settled yes; Q#RD9 is settled no and is withdrawn.

Q#RD2 conflated inspection with removal. Revision 1 removed the buffer
before the filesystem call, which fires arbitrary Lua `on_removed`
callbacks while the file still exists and accepts losing the buffer if
the deletion then fails. The sequence is now `stat/no-op -> enumerate
and validate -> mutate filesystem -> reconcile`. Validation inspects
`is_modified` and `editing_in_progress` without removing anything, so a
failed deletion leaves buffers intact automatically and `on_removed`
still observes the path already gone.

Q#RD3 overclaimed whole-batch atomicity. `documentChanges` are
sequential, so an earlier edit can dirty a clean buffer and an earlier
rename can move a modified buffer into a later delete's subtree, after
the snapshot. LSP 3.18 assigns `FailureHandlingKind.Abort` to any edit
containing resource changes --- "all operations executed before the
failing operation stay executed" --- so the protocol itself declines to
promise what revision 1 claimed. The preflight is now described as an
early conflict check, with robustness coming from per-op `pcall`, an
always-sent server response, and best-effort origin restore.

The lookup cannot be `EditorCore::find_buffer_for_path`: it normalizes
but delegates to the first-match-only `find_by_path`, and
`pmacs.buffer.from_file` creates path-bound buffers with no dedup, so a
clean first match can hide a modified second. Q#RD6 now requires a full
scan with component-aware `Path::starts_with`.

Recursive deletion now inspects the tree but reconciles only the exact
path, so the parked lifecycle defect stays exact-path rather than
becoming tree-wide. Q#RD4 holds at both layers, so the preflight cannot
reject an absent path the primitive treats as a no-op.

The prompt argument was overclaimed and that was my error.
`pmacs.lsp.send_response` takes `request_id` as an ordinary value, so a
`workspace/applyEdit` can be answered on a later tick, and a callback
continuation would reuse the existing minibuffer shadow rather than add
a seventh dispatcher rung. Prompting is expensive and separately
scoped, not impossible; the section now claims only what the evidence
carries.

Sweep found three more of the same defect class --- an absence or a
guarantee asserted rather than established:

  * a durable error surface does exist (`append_to_errors_buffer` ->
    `*errors*`), so Q#RD7 now records the refusal there as well;
  * no caller reliably surfaces a raise, because the async path routes
    uncaught coroutine errors through the undefined `pmacs.error`;
  * pmacs advertises no `workspace.workspaceEdit` capability at all ---
    no `documentChanges`, no `resourceOperations`, no
    `failureHandling`.

Adds seven acceptance pins with their bite obligations, adds the
`docs/active-work.md` lane the ledger requires for every open PR, and
drops the two-PR plan: #186 is revised in place and becomes the
implementation PR.

Still PROPOSED. No runtime code. Implementation begins only after
explicit user approval.

Levi Neuwirth 6fc7fee044 docs: absorb #174 and advance the anchors to 0442d78
#174 merged while this PR was open, so the lane it had just been given
is already a merged lane. Rule 4 removes those rather than relabelling
them — but only once the durable facts are in the handoff, so do both
here in that order.

docs/agent-handoff.md
- §5 gains the lesson: a wait predicate WEAKER than the assertion it
  guards is a race on whichever platform loses it, and "wait until the
  file mentions X, then assert Y" races whenever Y is stricter than X.
- Two things that generalize past the fix ride with it: a race you
  cannot reproduce can still be bitten at one remove (an unsatisfiable
  predicate proves the wait is load-bearing; the old predicate still
  passing proves a local run cannot tell them apart), and the obvious
  fix is sometimes worse — the sibling m4_26 is deliberately left alone
  because closing it the easy way trades a precise assertion diff for a
  vague five-second hang.
- Header and §1 anchor advance to 0442d78, noting #174 is test-only and
  #184 remains the substantive change at that head.

docs/active-work.md
- Remove the #174 lane; the header paragraph now says where it went.
- Canonical base and recovery floor advance to 0442d78. The floor
  explicitly rejects 6bee09d as well as 7fd646d, per its own rule that a
  check accepting an older commit than the declared base passes on a
  tree the file does not describe.
- Bottom-panel lane: 2B-2 is IN FLIGHT, not merely "next" — branch,
  worktree, and the fact it is branched fresh rather than stacked. Its
  boundaries are restated because they are easy to overrun: production
  Hello stays v20, panel_capable stays false, and 2B-3 may not simply
  bump the unsolicited Hello.
- dired lane: the re-scout is under way on the existing branch, so #171
  keeps its three-round history and the product is a rev 5.
- Both lanes note that main advancing to 0442d78 changes nothing for
  them, since #174 is test-only.

The bottom-panel framing doc keeps its 6bee09d ground-truth line: that
is a scouting statement about what was actually read, and re-anchoring
it to a commit nobody re-scouted against would be a false claim.

Levi Neuwirth a159200756 docs(active-work): give the two open PRs the lanes they never had
Neither #174 nor #171 had any entry in this ledger. An open PR is
exactly the volatile work the file exists to record, so its absence is a
defect rather than a tidy omission — #171 drifted 153 commits while
invisible here, and its still-green old CI run describes a tree nobody
has looked at since.

#174 — M4 config-sink race, revived and regated. Records the predicate
fix, the gate numbers on the integrated head 302c21c, and two things
verified rather than inherited: the "one writeln! is the only writer"
argument re-checked against a fake_lsp that DID change upstream, and the
wait bitten two ways (unsatisfiable predicate fails on the pump deadline;
the old predicate still passes locally, confirming a green local run
cannot tell them apart).

#171 — dired Stage 2 framing, stale, do not merge as-is. Measured 4
ahead / 153 behind with merge base c8ec8f3, which is itself #165's merge
— so dired Stage 1 and find-file are its base, not new arrivals. Names
the three landed changes that move ground under it: #178's
generated-buffer write invariant (dired is a non-adopting writer),
#182's demotion of dired to a replaceable directory-handler slot, and
#179/#181's typed-edit consumer chain. Restates the five-path-owner
rename transaction the framing still has to answer.

Also records that three review rounds in a commit history is not the
same as approval, and that dired 2a's file overlap with Journey 1b needs
assigning before either runs.

Levi Neuwirth e05ac819b5 docs: sync the durable records to landed main @ 6bee09d
PR #184 (bottom-panel Stage 2B-1) merged, but the four documents that
new work is supposed to start from still described it as open. Advance
every canonical anchor and close the one obligation that was blocking a
lane removal.

docs/agent-handoff.md
- §1's head-of-main anchor moves 7fd646d -> 6bee09d.
- State schema support and production advertisement as two separate
  facts: SUPPORTED is now v6..=v21, the server-first Hello still says
  v20, and #184 landed only the first.
- New §1 bullet for Stage 2B-1 carrying its durable substrate: the
  server-first incompatibility argument, the shared wire_grid boundary
  and why per-axis caps are a parameter, authoritative Absent, and the
  panel_epoch / geometry_epoch split.
- New §1 bullet for the PTY terminate diagnostic (#176), plus two §5
  ops lessons: a drain that ticks is not an observation, and how to
  prove a child exited without waitid or unsafe.

docs/active-work.md
- Canonical base and the recovery floor both advance to 6bee09d.
- Remove the #176 lane. It was retained only because rule 4 requires
  its facts to reach the handoff first; that move is in this commit, so
  the lane goes.
- Rewrite the bottom-panel lane as 2B-1 MERGED with 2B-2 next, branching
  fresh from landed main rather than stacking.
- Annotate the documentation lane with measured staleness (1 ahead, 320
  behind) without deleting it, since nothing has decided its fate.

docs/bottom-panel-stage2-framing.md
- Status header records 2A and 2B-1 as merged and 2B-2 as next. No
  revision bump: the header is landed state, and no design decision in
  the document changed.

COHERENCE.md
- §16 names #184 as the PR that landed the reserved v21 family.

No runtime code, no protocol change, no gate suite implicated.

Levi Neuwirth d0817314f9 merge: fold the terminal landed-docs PR (#180) into this branch
Two open documentation PRs editing the same three ledger files
re-conflict on every merge to `main` — the treadmill #169 and #176 each
paid three resolution rounds for. #180 was docs-only and already
CONFLICTING against `main`; folding it here retires one of the two
writers instead of resolving the same file twice.

Also integrates `githubsucks/main` @ `42025e4` (Lean 4 Stage 4b #181).

Conflicts resolved, and three claims corrected rather than picked:

* **The head-of-`main` anchor.** Both sides named `74301d1`, which is no
  longer true — `#181` has landed. The anchor now reads `42025e4` and
  leads with it, in `docs/agent-handoff.md` §1 and the active-work
  canonical-base line, and **the recovery floor moved with it**: the
  `git log` check requires `42025e4` or newer, per that section's own
  rule that a floor accepting an older commit than the declared base
  passes on a tree the file does not describe.
* **The Lean 4 bullet contradicted the anchor I had just written.** Its
  header still said "stages 1, 2, 3a, 3b LANDED" and its Stage 4b
  sub-bullet still said "implemented and in review", while the anchor
  above it now records #181 as merged. Both corrected: all six stages
  landed, #181 named.
* **The COHERENCE §2 grade.** #180's side still carried "broken at step
  3" / "Broken at entry" in both the ground truth and the §0 scorecard;
  this branch's corrections win, since they are what the code change in
  this PR makes true.

The removal note at the top of `docs/active-work.md` is reattributed:
the terminal config + copy mode lanes were #180's removal, and it now
says so and says why the fold happened.

Levi Neuwirth 7741cf806a fix(journey): honor the captured window, not the selected one
Review round 1 of PR #182. One implementation gap and two stale claims.

**The scope pins the frontend; it does not pin the window.** Framing
§4.4 specified `display{ window = dest:window() }`, but dired's commit
still ended in `pmacs.window.switch_buffer`, which targets whatever
window the scoped frontend has selected. A split or panel that took
focus while `read_dir` was pending therefore received the listing, and
`prev` was captured from it too — with every preflight check passing,
because the captured window was still live and still held its captured
buffer. Both sites now read the captured window: `display` routes to it
with `select = true` (the later `seat_cursor` acts on the active
window), and the `prev` read asks it directly.

N4c pins both halves. The suite's existing routing pins all varied
*frontend* identity; none varied the selected window within one
frontend, which is exactly why 23 green pins missed this. Bite: dired's
`display` back to `switch_buffer` fails N4c alone; `prev` read from the
ambient window fails N4c alone.

Two stale documentation claims, both of which this PR was supposed to
have already fixed:

* **The §0 scorecard still graded §2 "Broken at entry"** while §2's own
  ground truth had been rewritten. The scorecard is a second copy of the
  same claim and §25's protocol covers both. §19's row and ground truth
  were stale the same way — this PR creates the first cross-subsystem
  suite, which §19 says should exist and grades as missing — and are
  corrected too.
* **P4 still read "leaves exactly one buffer"**, the exact claim rev 6
  corrected as false everywhere else in the framing. Restated to what it
  actually pins: the file is in the *active window*. The test was
  already written correctly; only the framing lied.

Framing rev 8.

Levi Neuwirth d9d1c0b423 test(journey): pin the destination commit, and land the doc updates
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.

Levi Neuwirth d1bff6ac30 fix(lean4): count fan-outs where a claim cannot skip the count
Round 11 put the nesting count in the expander, which is optional. A
consumer at a lower priority can CLAIM and stop the chain before the
expander runs, while that fan-out's deferred-expansion subscriber still
runs — so the nested pass went uncounted, looked like the outermost
one, expanded early, and outer pairing resumed with a record the
replace had invalidated. `\alp(` gave `α(` again.

The count now comes from a no-op consumer registered at the minimum
priority, which runs first in every chain invocation that reaches any
consumer at all. Its guarantee is exactly the ordering contract the
chain already rests on, and it degrades safely: the only thing that can
skip it is a claim ahead of it, which skips the expander too, so
nothing is queued in that fan-out either.

The other plausible home does not work and the comment now says why: a
subscriber registered beside `run_deferred` is too late, because the
whole nested fan-out completes inside the OUTER chain's subscriber,
before either of them runs.

Acceptance 45o pins the short-circuit path — a consumer at 25 that
claims when the record is nil, so the nested pass never reaches the
expander. 45n passes against this bug, which is why both exist.
Counting in the expander fails 45o and nothing else.

Framing rev 12 also names the shape rounds 10–12 share: each fix was
correct about the failure it was shown and wrong about the boundary of
the mechanism it leaned on — the chain's copy semantics, then its
re-entrancy, then its short-circuit. A queue that outlives the thing
that filled it has to name that thing, not approximate it.

Levi Neuwirth 0d7ec7e3a6 fix(lean4): tie the deferred expansion to the fan-out that queued it
`buffer.after-edit` fan-outs NEST — the typed-edit contract supports a
consumer calling `pmacs.hook.run`, and typed_edit.lua's header says so
in its second paragraph. A nested run re-enters every subscriber,
including the deferred expansion's, while the OUTER chain is still
walking its consumer list and pairing has not yet seen the terminator.

So a consumer registered at priority 75 — between the expander at 50
and pairing at 100 — that runs one nested fan-out made `\alp(` yield
`α(` again: the nested pass consumed the queued expansion and edited,
and outer pairing then resumed holding a record the replace had
invalidated. That is round 10's failure reached through the chain's
documented re-entrancy seam rather than through claiming, which is why
deferring alone did not close it.

Deferring work past a fan-out means owning WHICH fan-out it belongs to.
The chain's subscriber and this module's each run exactly once per
fan-out, in that order, so counting invocations of the first and
matching them off in the second identifies the nesting level. Only the
outermost pass expands; a nested one leaves the expansion queued. No
new seam in typed_edit.lua, which is merged Stage 4a substrate.

Both halves bite: removing the level check and never counting
invocations each fail the new acceptance 45n.

Also fixes a test comment that still described the span design round 10
discarded — it claimed the expansion replaces the span "INCLUDING the
terminator". The behaviour asserted was right; the explanation was
stale. Framing rev 11.

Levi Neuwirth f3103a6953 fix(lean4): defer the expansion past the chain, and guard its point
Three defects, all about what happens AROUND the expansion rather than
about resolving an abbreviation.

A pair character that TERMINATES an abbreviation never reached
auto-pairing: `\alp(` gave `α(`. Q#LN22 already said the terminator is
not claimed and the implementation claimed it whenever an expansion
succeeded. Merely declining is not enough either — the chain hands each
consumer a copy of the record made before any consumer ran, so
expanding inside the chain invalidates the copy pairing is holding and
the closer is silently lost. Verified by mutation rather than assumed:
expand-then-decline reproduces `α(` exactly.

The expansion therefore runs on its OWN `buffer.after-edit` subscriber,
registered after typed_edit.lua's and before lsp.lua's. A claim stops
the chain but not a separate subscriber, which is the point: pairing
claims the terminator it reacts to. The replaced span now covers only
the leader and the typed text, so pairing's closer lands outside it and
survives. One undo restores the same text either way, because the
terminator was always its own insert.

That second subscriber is a new instance of Q#AP7 — lsp.lua flushes
didChange synchronously on the signature-trigger path, and `(` is a
trigger — so acceptance 45m pins it with the sighelp fake server: no
didChange may ever carry the unexpanded text.

The relevance check is now three-part, as pairing's has been since
#110: buffer, window, AND `ed.cursor() == rec.post_cursor`. A redefined
self-insert can insert the completing character and then move the
point, and expanding over a span the user has left teleports them back
into it.

Cursor placement after the replace is context-guarded, as
`repair_cursor` is. A buffer intercept may switch buffers while
`buf:replace` runs; the unguarded `goto_byte` then translated the Lean
buffer's pre-edit point through the Lean buffer's edit and applied it
to whatever was ambient.

Q#LN22, criterion 38's span wording, and the ledger are corrected to
describe the deferred design rather than the one that shipped — the
rationale's source, not only the sites quoting it. Acceptance 45j/45k/
45l/45m added; framing rev 10.

Levi Neuwirth d2ab3761c7 docs: correct the non-adopter attribution and two stale anchors
Round 6. Documentation only; no code, no protocol change.

1. **The four-writer table mapped the wrong buffers to `ensure_slot`.**
   Verified at the call sites: `ensure_slot` has exactly two callers,
   `*compilation*` (`compile.lua:1090`) and `*shell-command*` (`:1125`).
   `*search-results*` is an **independent panel** in
   `builtin/commands/default.lua` with its own intercept (`:869`),
   round-trip mark and writes; `compile.lua` declares its name only to
   answer a predicate (`:216`), which is what made it look like a third
   slot. Round 5 fixed an undercount and introduced a misattribution in
   the same paragraph — the count was right, the mechanism was not.

   The table is now keyed by **writer**, not by buffer, so the mapping
   cannot silently drift again: four mechanisms, five buffers. It carries
   an explicit "do not read `ensure_slot` as covering the search panel"
   note, because that is the specific wrong inference.

   Corrected identically in `COHERENCE.md` §14 and the framing's
   deferred-lane text, which both carried the error.

   The scope claim is narrowed with it. "Every generated buffer outside
   copy mode" was too wide: `*workers*`, `*help*` and `*buffer-list*` are
   generated but do not use this idiom, and the REPL package's intercept
   (`packages/repl/init.lua:187`) is an op-filtering editing policy
   rather than a read-only panel. The claim is now "every remaining
   intercept-protected writer", and the two excluded groups are named so
   the next reader does not have to re-derive the boundary.

2. **The recovery floor contradicted itself.** The canonical-base line
   said the check accepts `a27f646` or anything newer while the check
   below required `74301d1`. The floor genuinely advanced; the prose now
   says so outright — a tree at `a27f646` no longer passes — and states
   why the floor must move with the base rather than trailing it.

3. **Two anchors survived the integration.** Lean 4 Stage 4a said it was
   part of "the `fe8b8ba` anchor above" when the anchor had become
   `74301d1`; it now refers to the anchor rather than restating a commit,
   which is what let it go stale. And #168's closed entry called its own
   `fe8b8ba` figure "the live figure" — it is a reading taken at
   `1b6a084`, kept as history, and now says so and points at the
   coverage lane as the single authority with an explicit "do not quote
   this one forward".

Levi Neuwirth dd9f380533 docs(active-work): record Journey Stage 1a branch and ordering
Rev 5 is approved and the branch is cut, so the ledger's "no branch,
commit, or PR exists yet" line no longer describes reality. Records the
recovery command, notes that PR #177 has merged and therefore unblocks
implementation, and carries the standing obligation that dired Stage 2
re-scouts around commit_to before its branch is cut.
2026-07-26 16:39:59 -04:00
Levi Neuwirth d14fe4c4b9 Merge githubsucks/main (#169, #176) into docs-terminal-copy-mode-landed
Two doc conflicts, both in favour of `main`, and both are this PR's own
findings arriving from the other side:

- **The dired lane.** #169 did exactly what round 5 finding 5 said it
  would: absorbed dired Stage 1 into handoff §1 and removed the ledger
  lane per rule 4. This branch carried a placeholder saying #169 owned
  that text; the placeholder is dropped and #169's version taken whole.
  This is the rule working — one PR, one authority per paragraph.
- **The canonical base.** Both sides edited it. Resolved to `74301d1`,
  now naming #169 and #176, keeping `main`'s added guidance that a
  recovery threshold must move with the base it declares canonical (a
  check that accepts an older commit passes on a tree the file does not
  describe). The threshold moved with it.

Consequences of the merge, folded in:

- **The census is re-measured on the merged tree**: 3,176 vs 3,449 —
  still **273 dark**, 185 of them in the library. #176's six new tests
  are not `crdt`-gated, so both totals moved and the gap did not. The
  per-target table is unchanged.
- **The `crdt` Clippy failure is re-measured too, and the previous count
  was wrong** — it was read off a different checkout. At `74301d1` it is
  seven errors before the build aborts: four in `src/daemon.rs`, three in
  `tests/vterm_stage3_acceptance.rs`. Recorded as a **lower bound**,
  because Clippy abandons the remaining targets once one fails, and an
  older tree showed a further error in
  `tests/auto_indent_crdt_acceptance.rs` this run never reached.
- **The PTY-terminate lane (#176) is marked MERGED and retained**, with a
  note at its head saying why it survives rule 4: no landed-doc PR owns
  moving its facts to the handoff, so removing it now would delete the
  record rather than move it. The ledger preamble's stale-on-purpose
  paragraph is rewritten around that one lane; the Lean 4 and
  GPU-terminal-input headers it used to disclaim no longer exist.
- The flake note's "`src/process.rs` last changed by the Darwin PTY
  signal-name fix" is dropped — #176 changed it. The load-bearing half
  (#178 did not touch that file at all) is what remains.

Levi Neuwirth f8ca722d66 merge: integrate main (74301d1) into Stage 4b
Reconciles the handoff and ledger against a main that advanced past
this branch's base: the header, `main` anchor, and canonical-base
description take main's richer versions restamped to 74301d1, main's
new PTY-terminate lane is kept alongside the Lean lane, and main's
Stage 4a/rev-8 lane history is dropped in favour of the Stage 4b lane
that supersedes it — per this ledger's own rule to remove entries when
their PR merges.

Also fixes the coherence census's second count, which still said eight
settings three paragraphs below the nine it now lists.

Levi Neuwirth e4c9d65231 docs: fix five review-round-5 findings in the landed-doc refresh
Documentation only; no code, no protocol change. All five findings
reproduced before fixing.

1. The CRDT-dark census was stale. Re-measured at `fe8b8ba` under CI's
   exact flags versus the same flags plus `crdt`: 3,170 vs 3,443 —
   **273 dark, 185 in the library**, not the 264/177 #168 measured at
   `1b6a084`. The per-target table is regenerated (it gains a
   `terminal_copy_mode_acceptance` row, acc16e's, from this very arc),
   the rows are stated to sum to the total, and the lane now says the
   number moves with every merge and must be re-measured rather than
   quoted. #168's figure is kept as a dated historical reading with a
   pointer to the live one.

2. The generated-buffer non-adopter inventory was short by half. It is
   **four writers, not two**: listview panels (`listview.lua:60-61`),
   `*compilation*` **and** `*search-results*` — both through
   `compile.lua`'s shared `ensure_slot`, so naming only the first
   undercounts a mechanism rather than a buffer — and dired
   (`dired.lua:371`). All four pair an erroring intercept with
   `bypass_intercept` writes over a still-writable rope, and all four are
   emptiable by `M-x buffer.undo`. Corrected in the handoff §4 (as a
   table, with each writer's shape), `COHERENCE.md` §14, and the
   framing's deferred-lane text. The adoption estimate gains a
   consequence: the two `compile.lua` slots append and need a streaming
   variant; listview and dired are whole-buffer replaces and are the
   cheap half.

3. The ledger's canonical base still named `a27f646` while the same file
   recorded #168 and #178. Now `fe8b8ba`, with the recovery check's
   accept-or-newer floor moved with it — a stale floor is what lets a
   wrong base pass verification.

4. The completed terminal lane is **removed**, not marked complete. Rule
   4 of this file's own update protocol says a lane goes when it merges,
   and its opening contract says the file records only what has not
   landed. Its durable facts moved first: a new arc bullet in the handoff
   §1 (the snapshot materializes, so the dispatch-shadow count stays at
   six; `prune` reacts to removal rather than causing it; ownership means
   the handle table, never found-by-name; profiles are a raw Lua table
   and why the escape cache lives on `TerminalSession`; what criterion
   17 must assert when it can finally be written; the `cat -v` echo probe
   and count-don't-match rule), with the `set_generated_contents`
   invariant already in §4. A compact entry remains under "Closed since
   the last snapshot". The gate-run flake the lane carried moved to the
   CI `crdt`-coverage lane, which owns its discrimination — verbatim,
   including its explicit refusal to claim a root cause.

5. The refreshed handoff was internally stale: it anchors on a `main`
   that contains #179 and #165 while still calling both "in review".
   Both now read MERGED. Dired's durable facts are deliberately **not**
   absorbed here — that is open PR #169's job, and writing it from two
   PRs would put two authorities on one text — so the dired lane stays,
   with a note saying why it survives rule 4 and who removes it.

Also recorded while verifying finding 4's new home: the `crdt` Clippy
failure on `main` is re-verified with exact sites (four in `src/daemon.rs`,
one in `tests/auto_indent_crdt_acceptance.rs`), because any CI job that
compiles the `crdt` targets is red on arrival until they are fixed.

Levi Neuwirth a53965474d feat(lean4): the Unicode input method (Arc 8 Stage 4b)
Typing `\alpha` in a Lean 4 buffer gives `α`; `\<>` gives `⟨⟩` with the
point between them. The abbreviation table is vendored from
vscode-lean4 and the expander is a typed-edit consumer registered on
the Stage 4a chain at priority 50, ahead of auto-pairing.

The ordering is load-bearing. 64 abbreviation keys contain a character
in the `lean4` pair set, so with pairing first, typing `\[` would
insert `[]` and corrupt the pending key to `\[]` before the second `[`
arrives — `\[[]]` becomes unreachable. The consumer therefore claims
every keystroke that EXTENDS a pending abbreviation, not only one that
completes an expansion; claiming only completions would hand each
intermediate `[` to pairing by a different route.

The vendored table is an ORDERED SEQUENCE, not a map. Upstream breaks
equal-length ties by source declaration order — 101 prefixes depend on
it, and `\f` resolves through `f<` rather than `f>` — which a
`pairs`-iterated Lua table cannot express. `scripts/regen-lean-abbrev`
takes a vscode-lean4 commit, emits the file with its provenance header,
and aborts on a duplicate key, invalid UTF-8, or a round-trip mismatch.

Undo is cross-peer-degraded on CRDT frontends and that is accepted and
named, not papered over (Q#LN21): `\alpha` arrives as six source-peer
optimistic inserts while the expansion is one daemon-peer replace.
`set_round_trip_input` would fix it and also makes `dispatch_idle`
report false, so RET would stop inserting a newline.

Round 9 corrects three approved acceptance criteria that the real table
contradicts, found by simulating the state machine over all 1,855
entries and re-reading upstream at the pinned commit rather than
re-reading the prose. `\to` is not eager — `top`, `to0` and `toa`
extend it. `\zzzz` expands to `ζzzz ` because `ze`, `zeta` and
`zsqrtd` exist; only `$ % , ; @ W` open no key at all. And `\alpha`'s
undo does not restore `\alpha ` because `alpha` IS eager, so the
terminator is a separate edit. Criteria 38, 41 and 42 now state both
paths, and the false halves are asserted too: they read as correct
until the table is consulted.

Three implementation traps worth the record. The generator's own
round-trip check was broken twice and failed closed both times:
`str.splitlines()` splits on U+2028, which 53 symbols contain, and
escaping through `chr(byte)` produced a latin-1-shaped string that the
UTF-8 write re-encoded. The first check compared in-memory strings and
agreed with itself; it now stages the file, re-reads the bytes from
disk, and renames into place only on a match. And the expansion SHRINKS
the buffer, so the point must be placed explicitly — pairing's
no-cursor-motion rule holds only for an insert AT the cursor, and
without this every self-insert after the first expansion is silently
rejected and the editor looks dead.

25 acceptance tests plus one `--lib` test for the optimistic CRDT
producer (45f), which is where the gate list's `--features crdt` run
reaches it; a crdt-gated integration test would be dark in CI and in
the gates both. Fifteen mutations bite, each failing its target. Three
of these tests were vacuous when first written and biting is what
found them: the abandonment test asserted text a surviving record
would also produce, the re-arm test used an example that never reaches
the re-arm branch, and both switch tests ran through
`find_or_open`'s fresh-load path rather than `buffer.after-switch`.

No protocol change (Q#LN14). Also reconciles the handoff and ledger
for Stage 4a (#179) and adds `lean.abbrev` to COHERENCE.md's
config-registry adoption census, now nine settings.

Levi Neuwirth 44f5e44b9f docs: record #168 and #178 as landed, and the generated-buffer invariant
Documentation only; no code, no protocol change.

Handoff §1 anchors on `main` @ `fe8b8ba` and leads with terminal copy
mode (#178) and its landed-doc pair (#168). The active-work terminal lane
flips to BOTH STAGES MERGED, and the #166 lane records #168 landing with
what it measured: 264 tests dark workspace-wide for want of `crdt` in CI,
and the vterm audit's honest count of acceptances that drive a real
daemon (2, not 3).

The substantive addition is a new §4 substrate invariant for
`Buffer::set_generated_contents`, because it is now the one authorized
write for every generated buffer and three of its properties are
non-obvious enough that four review rounds were spent finding them:

- an intercept is not read-only — `Buffer::undo` reaches the rope through
  `ensure_writable` without consulting the intercept chain, and rebinding
  the undo chords does not help because `M-x buffer.undo` needs no
  keymap;
- a bare `set_read_only` would be worse than nothing, since it also
  refuses the owner's refresh — the pairing is the primitive, which is
  why no Lua `set_read_only` exists;
- a rope write is only half of an edit: the returned `Edit` must be
  fanned out, or a displaying window paints the new rope with stale line
  offsets and replica mirrors never import the write.

Also recorded: history clearing must clear whichever history the buffer
has (the v0.1 stacks are bypassed in CRDT mode), that `*compilation*` and
listview have NOT adopted the primitive and remain emptiable by
`M-x buffer.undo`, and that this does not replace `set_round_trip_input`
— the two guards cover different copies, and a daemon refusal arrives
after the frontend has already painted.

Levi Neuwirth 42f601a7ec Merge branch 'main' into gpu-terminal-input-docs, and refresh the ledger
The handoff's "last updated" paragraph conflicted; resolved by writing
the current statement rather than taking either side, and the same pass
clears the staleness the ledger had accumulated while five PRs contended
for it:

- Both head-of-main anchors (handoff §1 and the ledger's canonical base)
  now name a27f646, and list terminal config #173, the bottom-panel
  Stage 2 framing #175, Stage 2A #177 and Lean 4 Stage 4a #179 — plus
  the CRDT undo repro #157 and the inline-math landed-doc refresh #172,
  which are merged but had dropped out of both lists.
- The bottom-panel lane records Stage 2A as MERGED (#177 @ 0a3fcd1)
  instead of IN REVIEW, and states what 2B is: approved, unstarted,
  branching from main rather than stacking, with §7.2's criteria and
  §5.3's three-boundary trap named.
- The Lean 4 lane records Stage 4a as MERGED (#179 @ a27f646); its
  "framing-only, no code, awaiting approval" bullet was false.

The dired lane is left alone deliberately: #169 is the PR that records
dired Stage 1 as landed, and owns that heading.

Levi Neuwirth 23c966cc31 docs(terminal): restate criterion 17's bite for the fixed substrate
Review round 4, P2. A fix can invalidate a test that was never written.

Criterion 17 still specified the pre-round-2 world: remove
`set_round_trip_input` and the optimistic op "passes `ensure_writable()`
and mutates BOTH sides, silently, with no divergence to notice". That
was true while no Lua binding set `read_only`. Since
`set_generated_contents` does, the daemon refuses the op — so only the
frontend's own mirror mutates, and the copies diverge.

The gap matters precisely because 17 is unpinned. A real-GPU test
written to the old spec would hunt for a daemon-side edit that can no
longer occur and pass for the wrong reason, quietly readmitting the
round-2 regression through a test not yet built. The specification is
the artifact under review here, not the code.

Restated around unauthorized MIRROR mutation plus daemon refusal —
divergence — in all four places carrying the obsolete claim: the
criterion itself, the Q#TC6a heading, the acceptance-16 doc comment, and
the bite roster. The heading's "ONLY thing" now says what it is the only
thing FOR: the replica's own mirror. `docs/active-work.md` also still
described acceptance 16b as asserting `is_read_only()` is false, which
round 2 flipped.

Why round-trip input stays load-bearing rather than redundant, now
stated wherever the daemon guard is mentioned: a refusal arrives after
the frontend has already applied optimistically and painted. It buys
divergence instead of silent agreement; it does not prevent the mutation
the user is looking at.

Also recorded, after capturing it properly this time: the gate-run flake
in `cargo test --lib --features crdt` is
`process::tests::setsid_escapee_is_not_reaped_and_teardown_reclaims_readers`
(`active_reader_probe` -> None, "live runtime probe"), ~1 run in 5.
Pre-existing and unrelated — this branch does not touch
`src/process.rs`, the test passes 10/10 standalone and 2017/2017 at
`--test-threads=1`, and it is another instance of the known `drain_until`
trap: draining for `Started` also ticks, and a tick reaps the leader.
That also explains the unattributed "2 failed" run noted in round 2.

Levi Neuwirth 9e6c166c57 Merge branch 'main' into pty-terminate-eperm
Resolves the ledger conflict: keep this lane's PTY terminate section and
take main's newer Lean 4 lane heading verbatim. No content of either
lane is rewritten here.

Levi Neuwirth a0fb01f24c fix(buffer): fan out generated writes, and clear the history that exists
Review round 3, on the round-2 primitive itself. One lesson covers all
three findings: a rope write is only half of an edit, and "discard
history" means whichever history the buffer actually has.

P1 — the binding swallowed the edit. `set_generated_contents` returned
`()`, so nothing reached `notify_buffer_edit_to_windows`. Two
consequences, both reproduced by the reviewer. In the default build a
window showing the buffer kept a `TextView` line index describing the
PREVIOUS contents, and the next paint indexed the new rope with stale
ranges — `assertion failed: end <= self.len()` in `src/rope.rs`. In the
CRDT build `pending_crdt_ops` stayed empty, so replica mirrors never
imported the owner's write and their optimistic edits were generated
against content already replaced. The `delete`+`insert` pair this
replaced had done that fan-out for free.

Now applies ONE whole-buffer `Replace`, returns its `Edit`, and notifies
from the binding. The doc comment states the obligation, because the
next owner to adopt the primitive inherits it.

P2 — "discard history" was false in CRDT mode. The v0.1 stacks are
bypassed entirely there; the history lives in loro's `UndoManager`.
`read_only` stops the replay but not the retention, which is the memory
cost the contract claims to eliminate. `UndoManager` exposes no clear,
but needs none: it records only what happens after it is constructed,
the same property `CrdtState::from_bytes` already uses to keep the seed
insert out of undo. `CrdtState::clear_undo_history` rebinds a fresh
manager to the same doc.

P2 — the docs described the pre-fix architecture. Q#TC6a said no Lua
binding sets `read_only` and round-trip input is the only guard; the
acceptance text still said `is_read_only() == false` while 16b had been
flipped to true; `terminal.lua`'s comment repeated the obsolete claim.
The architecture is layered and now says so: rope-level read-only
protects the daemon copy, round-trip input protects the replica's
optimistic mirror, and neither substitutes for the other. Q#TC6a keeps
its analysis under a superseded-in-part box rather than being silently
rewritten — its conclusion survives, two of its premises do not.

New pins. acc16d paints the window after a SHRINKING generated write:
stale offsets then point past the buffer end, so the failure is the
reported crash rather than merely stale pixels. acc16e asserts the
refresh is queued for mirrors, through the real copy-mode path;
`crdt`-gated and therefore dark in CI, which is why 16d drives the
binding rather than the terminal. Plus a CRDT unit test that ten renders
leave the `UndoManager` with nothing recorded.

Bites: dropping the notify panics acc16d at `rope.rs:145` and fails
acc16e with `queued: []`; dropping the `UndoManager` rebind fails the
new unit test on `can_undo`.

Still open, and recorded in COHERENCE.md §14: the fan-out obligation
makes `*compilation*`/listview adoption more than a one-line swap.
