feat(churn): --in=DIR scopes recent changes to a directory, and the window discloses the merge bombs it skipped

[joyful-ii-V-I]

Lane lane/recent-scope for 0.6.1 (owner decisions 2026-09-12: C1-b, with merge_bombs_skipped= disclosed first). Three commits, one per defect.

The defects

1. The churn window hid the commits its merge-bomb rule skipped. gitLogDecayedFileMining skips any commit touching more than 100 indexed files and counted nothing about it, so a <recent> block could omit the very commit a question was about (a held-out gold commit with 71 source files was invisible) with no trace in the output. The three maxFiles sites the plan cites are at src/gitmine.h 1416 (recordCommitFileSet, co-change — already censused by bulkDropped), 1631 (resolveCommitStream, co-change) and 1968 (the decayed walk, the only one that feeds <recent>) on origin/main — not 1841/1968/2062; only the decayed walk needed the counter.
2. No directory scope for "what changed recently in DIR". --rank-by=churn-decay answered with a whole-repository symbol map plus one global <recent n="40"> block a directory with more than 40 recently-touched files never fits into; the sub-root workaround loses the global block and spells p= sub-root-relative, which missed every held-out gold (0/30 raw vs 19/30 prefixed — the coordinator's C1-r finding).
3. Found by this lane's llvm run: an all-merge-bomb window (a shallow clone of a large tree — llvm-project at depth 1 is one 183,835-file commit) printed no <recent> block at all, so the count added in (1) vanished on exactly the run that needed it.

The change

• <recent … merge_bombs_skipped="N"> on every churn-decay block, "0" included; the threshold is kChurnMergeBombMaxFiles = 100 (named, docs/LIMITS.md INDEXING, static_assert-pinned to the legend text); full legend and compact term (recent tag) define it. An all-bomb window prints <recent n="0" of="0" merge_bombs_skipped="N"></recent>; a tree with no git still prints no block.
• --in=DIR (kViewFlags row; root-relative, must exist under the root — inDirIsUnderRoot in main.cpp beside rootIsReadable; trailing slash ignored via sarif::rootPrefixOf, absolute and .. refused). The global block stays byte-identical (additive: q25/q26/q28's golds sit outside DIR). A second <recent scope="DIR" n= of= merge_bombs_skipped=> block follows it — rows from the same mining pass (recentRowsFromDecayedIf: a predicate + page window over the sorted rows; the global block is the admit-all instance, byte-identical), p= matched and spelled on serialize's own root-relative pathRel rule, same order. Paging is the house --offset=/--limit=: --in joins honorsPaging and both HONORED lists; 40 rows by default, capped="1" + next="--rank-by=churn-decay --in=DIR --offset=40" when DIR has more (--limit=N carried), offset= on a later page, an offset past the end is n="0". The symbol map collapses to <symbols total=N shown="0" next="--rank-by=churn-decay"/> — total= is keep (the un-stubbed header's shown=), the header's own shown= reads 0 under the stub, the <f> loop walks an empty order. Refused, naming the remedy, with any other verb, multi-root, --top-k=0, --json. MCP: the server exposes no rank_by, so there is no churn-decay twin to extend (checked src/mcpverbs.h, mcp.h, mcpserver.h).
• Not adopted, on purpose: the paging quintet (has_more=/next_offset=/limit=) on the scoped block. The owner's spec is n= of= [capped="1" next=]; n=/of= are the element's own count spelling (pageview.h rule 2) and next= carries the page verbatim (METHODOLOGY §9.3). truncvocabcheck and pagingsweepcheck (L) both pass; the (L) row records that the cut is on the child, as --flags does.

Measured (method: warm cache, bytes on stdout, wc -c; RocksDB @ 0e2801ac, read-only corpus, scratch cache)

run	bytes	scoped block	stub	global block
--rank-by=churn-decay (bare)	39,813	—	—	2,395
--in=db (of="300")	10,241	2,280	61	2,395
--in=util (of="115")	10,165	2,204	61	2,395
--in=table (of="126")	10,711	2,750	61	2,395

Release-notes line: 39.8 KB → 10.2–10.7 KB per scoped answer. Per the coordinator: the saving is the stub (61 B in place of the 200-row map); the scoped block itself costs 2.2–2.75 KB per answer. RocksDB reads merge_bombs_skipped="30"; this repository's own tree reads "5" (46,843 B → 9,259 B with --in=src). Compact legend on this tree: 1,783 B → 1,939 B under --in= (+156 B: scope=, total=, window terms); the gate-fixture map pin (810 B) did not move.

llvm-scale run (/Users/qgames/AppDevelopLocal/project2/rw-corpora/llvm-project, 183,835 tracked files, shallow: 1 commit; /usr/bin/time -l, scratch cache, two warm samples each, corpus untouched):

run	real	user	sys	max RSS	bytes
cold prime, bare (uncounted)	5.99 s	50.74 s	1.45 s	2.66 GB	47,967
warm, bare	2.41 / 2.41 s	2.20 / 2.19 s	0.50 / 0.49 s	2.24 GB	47,967
warm, --in=llvm/lib/Analysis	2.42 / 2.44 s	2.19 / 2.22 s	0.49 / 0.49 s	2.22 GB	5,676

The per-file pass costs nothing measurable. Honest caveat: because that clone's only commit is a merge bomb, every file weight is 0 and the prefix predicate short-circuits — the 183k-file loop is exercised, the rootRelativeUri compare is exercised at scale only on RocksDB (1,857 touched files). Determinism (--in twice byte-identical) and xmllint hold on both corpora.

Gates (all on build/ripwire; result lines)

• recentscopecheck ALL PASS (54 PASS) — red-first: 39 FAIL on the pre-change binary (unknown flag). churndecaycheck ALL PASS — arm 7 red on the pre-change binary (7a/7d/7e/7f FAIL: no attribute anywhere); arm 7h red on the commit-2 binary (prints no <recent> block (got: '')).
• Both gates ALL PASS under asan/ripwire (LSan suppressions); direct ASan runs on this tree (--in=src, page 2), RocksDB --in=db, llvm --in=llvm/lib/Analysis: exit 0, 0 sanitizer lines.
• ALL PASS: compactlegendcheck, legendcoveragecheck, legendcostcheck, floormarkcheck, testgatelegendbudgetcheck, printffmtparitycheck (42 verbs), xmlwellformed, mcpattrparitycheck, flagtablecheck, flagsurfacecheck, modifierguardcheck, guardmsgcheck, shapingflagcheck, helpbudgetcheck (tier 1 ~4,871 tokens / 7,000), emptyvaluerefusecheck, jsonparitycheck, docscommandscheck, manifestcheck, gatecountcheck, limitstablecheck, clicheck, sincecheck, pagingsweepcheck, testgatepagecheck, truncvocabcheck, nextverbcheck, listingpagingcheck, paginationcheck, g1freshcheck. Generators: gatecount 612 → 613, LIMITS (209 caps, 112 classified), COMMANDS.md regenerated — all --check clean.
• --quality-delta gating="0" on each commit (one --ack-only=gating ack on writeRecentRows, the attribute's emitter, one +ack row; the first cut of commit 2 cloned sarif::rootPrefixOf and pushed churnRankedGraph over the complexity bar — both fixed by reuse and by lifting scopedRecentPage, not acked).

CI round 1 (ac99f646)

Three reds on the first CI run, fixed in one push: capsweep's docs/TUNING.md regenerated (the named constant moved the cap census 126 → 127 / 125 → 126; five count lines, nothing else); 25 single-line … && ok … || no … verdict sites in my two gates converted to the wrapped spelling G2 accepts (G2 now lists 0); and --in covered in the showcase capture — one case added to test/showcase_capture.py and its section (the tool's own rendering) spliced in as a 38-line pure insertion, so the capture does not republish this machine's 136 local lane/ branch names as a full regeneration would. One composition to know: --in joined the --limit/--offset-honoring set, where the existing guard reserves --top-k to --graph-query, so --rank-by=churn-decay --in=DIR --top-k=N refuses loudly; under --in the map is a stub, so the refusal costs nothing honest.

CI round 2 (030df037)

Five deterministic rows on 14 jobs: fixedbufsweep S1/S2/S6 (the scoped open tag, its offset= and the stub went through fixed char[] buffers after the escaper — all three now compose on std::string, returning rc to its two pinned sites and the S6 population to its pins: 322/218/218/92, nothing moved); readmedriftcheck (B) and deckclaimcheck (README ×3 and the deck ×3 said 179 long flags; 180 with --in); mcpcontractcheck (G) (--in classified CLI-only in the TWIN table). Full suite run twice per the lane rule: first gates=627 pass=622 skip=2 fail=3 (deckclaimcheck — fixed; g1freshcheck — asan/ predated the serialize.h edit, rebuilt; strkerncheck — TIMEOUT at its 300 s budget under -j 6, the documented contention trap, 155 s and PASS alone), then gates=627 pass=625 skip=2 fail=0 wall=1058.1s jobs=6 tree_writes=0.

Pins moved

• test/printf_parity.manifest: labels help, help_all (the new --help entry; UPDATE_GOLDEN_EXPECT="help help_all", 40 labels unchanged).
• kTotalFlagArms 209 → 210 (--in=).
• test/pagingsweepcheck.sh (L): a --in invocation row (the arm derives its universe from --help).
• test/churndecaycheck.sh arm 6a: of="2"> → of="2" (the tag no longer closes after of=).
• Not moved: compactlegendcheck ripwire.map/v1 pin 810; no LIMITS cap changed value.

CodeRabbit round + merge with main (516d7c4d)

Review 5189303726, both threads, one push.

1. src/cli.h:4224 (Major) — --in=DIR was accepted and ignored whenever a report verb won dispatch. --in has exactly one consumer, the default map's churn-decay branch (runDefaultMap → churnRankedGraph → scopedRecentPage). validateModifierGuards judges what cli.h can see alone (rankBy, root count, --top-k) but not which verb will WIN dispatch, so ripwire . --rank-by=churn-decay --in=src --lint exited 0 with an empty stderr and scoped nothing. The refusal now lives in refuseInertMainModifiers (src/main.cpp), after scanReportVerbPrecedence resolves the winner, and names it. The condition is the winner's mere existence — not a verb list — for the same reason htmlPreemptedBy beside it derives rather than enumerates. --query is covered too: it reaches runDefaultMap but through the lexical branch that replaces the churn ranking, so no <recent> block is built there either.
2. test/recentscopecheck.sh:159 (Minor) — grep -q 'capped=\|next=' is not POSIX alternation. Both sites are grep -qE 'capped=|next=' now; the sweep over every line this lane adds to recentscopecheck and churndecaycheck found no other \|. Honest caveat: neither /usr/bin/grep nor the grep on PATH here reads \| literally, so the defect does not reproduce on this machine — which is why arm 7c now carries a mutation control that feeds the pattern a synthetic tag with capped=, one with next=, and a clean one, proving both negative arms live on whatever grep runs them.

Red-first: arms 6l/6m/6n (--lint, --hotspots, --query as dispatch winners) all report exit 0, expected 1 with an empty stderr on the pre-change binary — the defect verbatim. 42 arms red on the pre-lane binary (0.5.0: unknown flag), 58 PASS / ALL PASS now, and ALL PASS under asan/ripwire.

Merge with origin/main (f6a2716 — #209, #213). Nine conflicts, all from #213 landing --for into the paging surface --in joined; both sides kept everywhere. src/cli.h ×3 (the --help HONORED line, kPagingHonoringVerbs, honorsPaging() — both lists now read --situ --in --for in the same order, which pagingsweepcheck (L) derives its universe from); test/regression.sh (recentscopecheck re-inserted beside forwidencheck — 614 gates); pagingsweepcheck (L) and mcpcontractcheck (G) table rows; CHANGELOG both entries. The three generated docs were resolved by regenerating on the merged tree, not by picking a side: LIMITS 209/210 → 211 caps (114 classified), capsweep 128/129 → 129 declarations / 128 names, gatecount 613 → 614 (8 sites, 3 files), COMMANDS.md 176 flags, documented set == binary set and carrying both the --in=DIR section and --for's file-page paragraph. All four --check clean.

Pins moved: test/printf_parity.manifest — help 3290aebf → 29953013 and help_all b11003a2 → cbf72644, re-measured on the merged tree (UPDATE_GOLDEN_EXPECT="help help_all" matched, 40 unchanged). Only help_all conflicted textually; help merged cleanly to main's hash and was wrong, because the merged --help carries both sides' edits to the same paragraph. Nothing else moved: the README/deck "180 long flags" claim did not (main never touched it — git diff <merge-base> origin/main -- README.md is empty; flagsurfacecheck harvests 180 from the merged --help; --for is not a new flag, it joined a set), and kTotalFlagArms stays 210.

build/ and asan/ both rebuilt --clean-first after the merge.

Full suite (foreground, after the merge): gates=628 pass=626 skip=2 fail=0 wall=731.2s jobs=6 tree_writes=0 — the two skips are the environmental ones (argvdiffcheck, editchecknotecheck: no RIPWIRE_BASE binary). The first post-merge run was fail=1 on versioncheck alone (built_from=1f432a78b+dirty: the binary was clean-rebuilt before the merge commit existed); a relink refreshed the stamp to 516d7c4d7 and the re-run is the clean line above. --quality-delta gating="0" (--quality-delta=origin/main..HEAD: regressions=10, 9 minor, 1 new-symbol, none gating).

Fable review round (996dbb80, fd8ec444, 696b42de)

A ten-finding review of 516d7c4d, all red-first, plus the two things the review round itself left behind.

The ten

1. The stub borrowed a vocabulary it was not entitled to. It printed <symbols total="200" shown="0"> — total= was the --top-k page size, on a document whose own header says symbols="18457", with no capped= beside the shown= rule 3 requires. It says what it is now: <symbols stubbed="1" would_show="N" next="…"/>. would_show= is keep, a function of topK and S alone, and equals the un-stubbed header's own shown= (verified on this tree: shown=200 = 193 printed rows + 7 overload-merged defs).
2. next= named a different corpus. Both next= strings were hand-spelled --rank-by=churn-decay [--since=V], dropping --exclude/--no-ignore/--ignore-tests: --in=db --exclude=db/f00.py reported of="44" and handed back a page of 45. One composer (scopedMapNextInvocation) builds both now, replaying the flags that decide which rows exist — corpus and window — and no presentation flag, which cannot move of=. Past kNextAttrMaxBytes it returns "" and has_more= still says the page exists. Verified: --in=src --exclude=src/mcp now emits next="--rank-by=churn-decay --exclude=src/mcp --in=src --offset=40" and of= moves 169 → 162.
3. DIR was validated against the filesystem, which answers a different question. On APFS --in=DB is a directory; a symlink alias is a directory; a subtree --exclude dropped is a directory. All three exited 0 with n="0" of="0" — the typo-reads-as-nothing-changed answer the refusal exists to prevent. inDirMatchesCrawl now requires at least one indexed file spelled DIR/, byte-exact, and names the three causes; the fs check stays as the cheap first reject.
4. The refusal knew only the verbs one table lists. --in=src --map-diff exited 0 with 28 KB, zero <recent>, zero <symbols> and a header still reading rank_by="churn-decay"; so did --expand/--outline/--pack-signatures, --doctor, --batch, --mcp and the CLI edit bridge. It is derived from the flag tables now (inPreemptedBy, htmlPreemptedBy's shape) and refused at the top of dispatchMain, ahead of every one of them. kInHosts declares --in's hosts the way kSinceHosts declares --since's, so the planned --for --in=DIR is one row.
5. A modifier was sitting in a verb list. --in in kPagingHonoringVerbs made validateShapingFlagsHonored refuse every --top-k/--max-tokens/--token-budget beside it, with a message handing the caller a list of verbs and claiming the default map honours the budgets it had just refused; --top-k=0 printed three refusals. --in left that set: the scoped element pages, --top-k refuses for any N in one message of its own, and the byte budgets compose. Verified: --top-k=5 and --top-k=0 each print exactly one line; --token-budget=20000 composes at exit 0 with empty stderr.
6. The bomb rule counts indexed files; both legends said "files". A commit of 120 .txt and one .py is not skipped, so the prose described a different rule from the code's — including the anecdote in gitmine.h, which named a commit this rule does not skip. Both legends and LIMITS say "more than 100 indexed files" now, the two --rank-by=churn walks use the named constant where they kept a literal 100 beside a comment claiming parity with it, and the window's merge_bombs_skipped= no longer rides the scoped block, where it read as "N commits under DIR were skipped".
7. The compact dialect paid for the prose it replaces. The in=DIR clause had no kCompactProsePrefixes row, so ~640 B survived beside the compact terms and was charged into est_tokens. Registered; arm 9e2 asserts the clause is gone, not merely that the terms are defined.
8. The scoped block hand-built its paging half. It goes through pagingDisclosure now (with a new emitTotal=false — the judgement secondaryCutAttrs' totalAttr=nullptr already makes: of= is the total, and one number under two names makes a parser guess whether to add them), capped= rides its n= unconditionally per rule 3, and one writeRecentBlock emits both blocks. Its absence rule is the global block's now: a run that mined nothing printed no global block and a scoped n="0" of="0" anyway, claiming to have looked under DIR when no commit was read at all.
9. The discarded map was still being computed. Under --in the whole map was resolved, PageRank-ranked, radix-sorted, bucketed into a files-sized allocation and token-estimated, then thrown away for the stub; the decayed rows were sorted twice, with a second uncached git log -1 popen for a number the process already had. The ranking, sort, buckets and estimate are skipped (the header carries no pr_iters= for an iteration that did not run — verified: zero occurrences under the stub), the rows are built and sorted once for both pages, and the HEAD epoch comes from the cached reader.
10. Docs and gate hygiene. --help and the CHANGELOG carry the real refusal set. The CHANGELOG's two retrieval claims name their corpus and method (the frozen 30 on RocksDB @0e2801ac, root-prefixed scoring) instead of floating as bare fractions. churndecaycheck arm 6a pins the global tag's closed attribute set again — it had been loosened to a prefix, which is how the window's merge_bombs_skipped= reached the scoped block unnoticed. The capture's --in section is re-spliced (not regenerated: test/showcase_capture.py scouts local branch names) with a window narrow enough that the scoped block, its paging half and the stub are visible. The CHANGELOG also records what is still undisclosed: --cochange, --situ's partners and --pr-context skip at a cap of 30 with no counter at all.

Two things the review round left behind (696b42de)

• A gating row it reported as clean. The round reported --quality-delta gating="0" from the sidecar form, which on a clean tree compares a commit with itself and can only ever say zero — it was not evidence about this lane. --quality-delta=origin/main..HEAD reports complexity churnRankedGraph was=18 now=24 against a bar of 15, gating="1": C1-b's stub branch, zero-filled rank vector, build-and-sort-once list and scoped page all landed inline in a function already over the bar that is a three-way dispatcher. The answer to a dispatcher growing a fourth concept is a name, not an ack — the churn-decay arm is lifted whole into churnDecayRanking, and the lambda the three arms shared becomes discloseUniformChurnFallback. gating="0" now, with no new ack: the row is gone, not suppressed.
• A doc comment cut in half. Moving kChurnMergeBombMaxFiles above churnTeleport (item 6) dropped it into that function's own comment, leaving "The emitting verb needs that fact to stamp it" dangling and orphaning the line that finishes it. The constant moves above the whole block.

Re-measured, on the pushed head (837997f7)

RocksDB @0e2801ac, warm cache, bytes on stdout via wc -c, --rank-by=churn-decay:

run	bytes	of=	scoped block
bare	39,942	1,857 (global)	—
--in=db	10,601	300	capped="1" has_more="1" next_offset="40" offset="0" limit="0"
--in=util	10,525	—	—
--in=table	11,071	—	—

The global block reads merge_bombs_skipped="30", the stub <symbols stubbed="1" would_show="200" next="--rank-by=churn-decay"/>. These reproduce the CHANGELOG entry's figures exactly.

What the review round cost in bytes, stated because it is a cost: the same --in=db answer was 10,241 B on 516d7c4d and is 10,601 B now — +360 B, which is the paging half (has_more=/next_offset=/offset=/limit=), capped= riding unconditionally per rule 3, the longer next= that replays the corpus flags, and stubbed=/would_show= in place of total=/shown=. Every one of those bytes is a disclosure the old answer did not make.

Timing, re-measured A/B — 516d7c4d built from git archive into a scratch tree, the two binaries run interleaved, five warm samples each, own scratch cache file per binary, /usr/bin/time -p user time, --in=db on RocksDB:

sample	516d7c4d	837997f7
1	0.85	0.79
2	0.84	0.82
3	0.83	0.82
4	0.85	0.81
5	0.85	0.79
median	0.85 s	0.81 s

~4.7% — the same direction and roughly the same size as the 0.73 s → 0.71 s the CHANGELOG entry records by the same method. The absolute user times are higher here than in that entry on both sides; user time on a loaded machine is not portable between sessions, and the entry's honest caveat stands either way: ingest and the call graph dominate the run, and the ranking this skips is only a few percent of it.

Gates

• Full suite, foreground, on the pushed head: gates=628 pass=625 skip=2 fail=1 wall=1578.0s jobs=6 tree_writes=0. The two skips are the environmental ones (argvdiffcheck, editchecknotecheck — no RIPWIRE_BASE binary). The one fail is strkerncheck TIMEOUT at its 300 s budget under -j 6 — the documented contention trap; run alone it is strkerncheck: PASS (137 s, all 26 assertions plus the Rosetta AVX2 mirror and its mutation control). Same shape on the pre-merge run of 02f52730: gates=628 pass=625 skip=2 fail=1, the same single gate.
• The first run of this round was fail=3, and all three were mine: g1freshcheck (asan not yet rebuilt after the refactor), versioncheck (build/ linked before the commit existed), and readmeexamplecheck — a real consequence, since churnDecayRanking is a new caller of rankGraphTeleport and README's two --callers captures pin that list. Both captures re-taken from the live binary (count="6" → count="7", the new row, and block 2's graph_ambiguous=/graph_unresolved= refreshed to the live values); the two prose sites quoting count="6" moved with them.
• --quality-delta=origin/main..HEAD (bcae1fdf..837997f7): gating="0", exit 0 — regressions="10" minor="9" acked="6" preexisting-worse="9" new-symbol="1". No ack was added for the churnRankedGraph row; it is gone because the function was split, not suppressed.
• Determinism and well-formedness re-run on the stubbed document: --rank-by=churn-decay --in=src twice is byte-identical and pipes clean through xmllint --noout.
• Generators --check clean after the merge: gatecount 614, LIMITS 211 caps / 114 classified.

Merge with origin/main (bcae1fdf, #221)

One conflict, CHANGELOG.md, both sides kept: #221 adds the 0.6.1 reference-guide verification entry beside this lane's two, and neither entry touches the other's subject. Main's change is CHANGELOG-only (git diff --stat 0e3573af origin/main is one file, 49 insertions), so no source moved under either build and no pin needed re-measuring. build/ and asan/ both relinked; --version reads built_from=837997f7f.

Pins moved in this round

None. Not moved and re-checked: the compact map pin, the flag count (180), the gate count (614), kTotalFlagArms (210), test/printf_parity.manifest (all 42 labels), and no LIMITS cap value. README.md's two --callers captures are a capture, not a pin, and the gate that reads them (readmeexamplecheck) compares name+file and ignores the line suffix by design.

CI round 3 — one gate, red on every shard that ran it

legendcoveragecheck (E) was red on macOS Release 2/4, macOS plain 4/4 and ubuntu clang Release 2/4, and green in the local full suite. The difference was the checkout path length.

The defect. Arm (E) needs a document that has climbed rung zero of the --for ceiling ladder, so it asks for one with a tight --token-budget. But the budget is charged against the document's own bytes, and the document carries root="…" — its own checkout path. The rung's top edge is therefore a function of how deep the tree happens to be checked out. Bisected on the merged tree, same commit and binary, only the root differing:

root length	rung zero fires at	not at
38 chars	1287	1288
137 chars	1323	1324

The probe was 1300 — between the two. A developer worktree sat inside the band; every CI runner (33 characters on Linux, 34 on macOS) sat outside it. The arm then printed its own honest refusal, "the probe no longer climbs rung zero, so this arm checks nothing" — the gate working correctly on a probe that was not. The comment beside the roster row recorded the band as "~1100 to ~1340", and that measurement had only ever been taken at one path length, which is how the edge stayed invisible.

The fix, at the note's depth and not at a tolerance. The note itself was never wrong: it is composed from the clauses actually dropped (kForLegendDroppedNote), never a constant, and at every budget inside the band its text and arm (F)'s census are byte-identical — measured from 100 up to the edge, both dialects, both roots. The band has a flat floor and only its top edge moves, so the answer is to sit in the middle of it:

• TIGHT 1300 → 900, with 387 tokens of headroom below the shorter edge, and the two-root measurement written down beside it instead of a single-machine one. The two roster rows that probe the same rung (for-budgeted, for-budgeted-compact) moved with it, so the roster covers the same document everywhere rather than a different one per machine.
• A new MARGIN row gates the headroom: the same query 200 tokens above TIGHT must still climb rung zero. This is the row that would have caught 1300 on the machine that chose it. "The probe has headroom" stops being a claim in a comment and becomes a row that fails when it stops being true.

Nothing was loosened: the arm still requires the note present at TIGHT, absent at the WIDE control, and every name it spells defined at WIDE.

Red/green, two root lengths, one binary:

	root 38 (CI length)	root 137 (worktree)
before	FAIL — "note is ABSENT at 1300", names_checked=6	PASS, names_checked=14
after	ALL PASS, names_checked=14	ALL PASS, names_checked=14

That top row is the CI/local split reproduced locally, from one binary, with only the root differing.

Mutation controls, both fire. MARGIN pushed to 1300 reds the new row on the 38-character root ("the probe is within 200 tokens of the rung's TOP edge"); TIGHT restored to 1300 reproduces the CI failure verbatim on the same root.

One self-inflicted red, caught by another gate: the first draft of the new comment spelled the literal CI paths, and ripwirepubliccheck arm 2 refused it — an absolute home path in a tracked file, which it cannot distinguish from a person's. The comment states path lengths now. That is the gate being right, and it is recorded here because a reviewer should see it was caught rather than avoided.

Merge with origin/main (c1915d21, #218)

Two conflicts, and one was the gate-list population trap rather than text.

• test/regression.sh — both sides edited the same for _g in … loop and both sides had 614 names, so taking either whole would have silently dropped a gate: ours adds recentscopecheck, feat(route,skills): the router knows the recency question and the widening page, and every new shape is named on an agent surface #218 adds agentsurfacecheck. Resolved as the union, computed rather than eyeballed (set difference each way, one name on each side, reinserted at its HEAD position, duplicate check, 615 distinct). The count is a build product: docs/gatecount_build.py regenerated 614 → 615 across 8 marked sites in 3 files, --check clean. LIMITS unchanged at 211 caps / 114 classified.
• CHANGELOG.md — three entries, all kept. feat(route,skills): the router knows the recency question and the widening page, and every new shape is named on an agent surface #218's entry already names --in=DIR and --rank-by=churn-decay as the scope its router learned to reach, which is this lane's flag; the two describe the same feature from opposite ends.

test/legendcoveragecheck.sh auto-merged — #218's four added lines and this lane's rung re-anchor touched different parts of the file.

#218's agentsurfacecheck self-heals on this lane, and it does. It is the gate asserting a new flag is named where an agent reads, and on the merged tree it reports three rows that could not pass before this lane landed the flag they name: --in= beside --rank-by=churn-decay (skills/ripwire-fresh-eyes/SKILL.md:54), scope= beside --in= (:55), merge_bombs_skipped= beside the ranker (:50). ALL PASS, non-vacuously.

The band was re-measured after the merge, because #218 added a 385-line file to src/ and the probe's --for runs over that corpus: the 38-character edge moved by a single token (1288 → 1287) and the 137-character edge from ~1310 to 1323. The conclusion and the fix are unchanged — 1300 still sits between them — and that a merge moves the edge at all is the argument for the MARGIN row rather than against it.

Final gates (head 3c191bdf)

Full suite in the foreground, from both path lengths, on the merged tree:

checkout	path length	suite line
developer worktree	137	gates=629 pass=627 skip=2 fail=0 wall=939.4s jobs=6 tree_writes=0
CI-length checkout	38	gates=629 pass=626 skip=3 fail=0 wall=782.8s jobs=6 tree_writes=0

fail=0 at both, and strkerncheck did not time out in either. The short run's third skip is w3fixlegendcheck's own arm-level tie skip (N=3 … TIE 0.0928 vs 0.093 … refutes nothing; asserts nothing) — checked at both paths twice each and byte-identical every time, so it is not path-dependent; only pargates' pass/skip classification of that gate differed between the two runs, which is worth a look but is neither new here nor a failure. The other two skips are the environmental pair (argvdiffcheck, editchecknotecheck).

Gates re-run individually on the merged tree, all PASS: agentsurfacecheck, taskroutecheck, legendcoveragecheck, recentscopecheck, churndecaycheck, manifestcheck, gatecountcheck, limitstablecheck, nextverbcheck, routehookcheck, ripwirepubliccheck.

Pins moved in this round: the gate count, 614 → 615, by the generator, because the merge's union added agentsurfacecheck beside recentscopecheck. Nothing else: no LIMITS cap value, no legend byte pin, no printf_parity label, kTotalFlagArms still 210.

CodeRabbit round (review 5192382995) — the pasteable attribute was not pasteable

One thread, valid, fixed at the source and not in the capture.

The defect, in two individually reasonable steps. nextFlag (src/nextverb.h) treated ~ as a shell metacharacter anywhere in a value, so HEAD~1 was single-quoted. The value then goes into an XML attribute, where the escaper correctly turns ' into '. The capture published:

next="--rank-by=churn-decay --since='HEAD~1' --exclude=test …"

A reader whose parser decodes the attribute is fine; anyone pasting the raw text — out of a captured showcase, a doc, a scrollback — gets a literal ' no shell decodes. next= exists to be pasted, so on the commonest git revision spelling there is, it lost the whole of its job.

The fix is the shell's own rule, not a special case for git. Tilde expansion is defined for a word-initial ~ and the ~user form; a tilde anywhere else in a word is an ordinary character — HEAD~1, HEAD~3, v1.2~rc1 were never special. The check is position-aware now: ~ forces quoting only at index 0 of the value, which also covers the empty-flag callers where the value is the whole word (editplan.h's git -C <root>). Everything else is unchanged — space, $, backtick, quote, backslash, ;|&<>(), glob characters, {}, !, #, and a leading ~ all still quote.

Gate: nextverbcheck arm (9), on its own two-commit fixture repo rather than this repository's live history (HEAD~1 here names whatever this lane last committed — the live-tree-as-fixture trap). The two rows are each other's control, so neither needs a planted mutation: a rule that quoted nothing reds the ~tmp row, a rule that quoted everything reds the HEAD~1 row, and only the position-aware rule passes both.

	before	after
next= carries a bare --since=HEAD~1	FAIL	PASS
next= carries no '	FAIL	PASS
a leading ~ is still quoted (--exclude='~tmp')	PASS	PASS

The capture was re-spliced, not hand-edited, and that mattered. Editing the two next= strings in place was the obvious cheaper fix and is wrong: est_tokens= is not independent of those bytes. Measured on this tree with two --exclude values that match nothing and differ only in whether they quote (zzzz vs ~zzz, same corpus, same rows): 3237 against 3247. A hand edit would have left a header number describing a document that no longer existed, and computing the replacement by hand would be publishing a number no run produced. The section is formatted by the generator's own explode/fmt_block, lifted out with ast the way showcasecapturecheck arm (B) does, and re-spliced rather than fully regenerated because showcase_capture.py scouts local branch names for its --stray-content case.

The demo's window moved HEAD~1 → HEAD~7, because HEAD~1 had stopped demonstrating anything. It now spans one commit touching one file, so the block printed of="1" capped="0" — no paging half, no next=, the case showing none of the three things it exists to show. N is now chosen by a written-down rule (smallest N whose scoped of= exceeds the --limit, with the global block still inside the 30-line display cut) and with a margin of at least one commit on either side, because the commit that lands a regenerated capture is itself a commit and shifts every HEAD~N in it. That is not hypothetical: it moved twice while this was being written. Measured at d48f6eaa: HEAD~3 → of="1"; HEAD~4..6 → of="4"; HEAD~7 → of="5", global n="13"; HEAD~10 → global n="32", past the cut. The block now carries scope="src" n="3" of="5" capped="1" has_more="1" next_offset="3" offset="0" limit="3", a pasteable next=, and the <symbols stubbed="1" would_show="200"> stub, at at="f86bad879" — a committed tree, not +dirty.

docs/COMMANDS.md regenerated: it embeds 162 samples from the newest capture, so re-splicing left it describing a block that was no longer there, and docscommandscheck arm (G) caught it. 176 flags, documented set == binary set; ten lines move and all ten are the --in sample.

Full suite (head b86fba9f): gates=629 pass=627 skip=2 fail=0 wall=1838.4s jobs=6 tree_writes=0 — the two skips are the environmental pair. Targeted first: nextverbcheck, recentscopecheck, churndecaycheck, showcasecapturecheck, docscommandscheck, ripwirepubliccheck, versioncheck, all PASS.

Pins moved: none. The flag count stays 176, the gate count 615.

Gate-count merge trap — verified, and the doc that described it corrected

No merge was pending when this came in (origin/main is still c1915d21 and already an ancestor of this lane), so this round is the verification plus one doc fix. The recipe will be applied as-is when the other lanes land: union the for _g in … loop, run docs/gatecount_build.py with no --check so it WRITES, then --check both generators.

The mechanism is exactly as described, confirmed with git merge-tree between two lanes in the current queue (#212 × #215): README.md, docs/EVALS.md and present/deck5_ripwire_build.js all auto-merge clean at 615 with no conflict markers, and only test/regression.sh conflicts — so the loop is the one place a resolver is forced to look.

The queue's arithmetic checked by set union over the four open heads rather than taken on trust:

ref	loop	vs main	published
origin/main c1915d2	614	—	614
#212 lane/recent-scope	615	+recentscopecheck	615
#214 lane/tests-rows	614	none	614
#215 lane/sc-legend	615	+scroundtripcheck	615
#219 lane/situ-shape	615	+situshapecheck	615

Three distinct additions, no overlap, so the loop after all four land is 617 — the coordinator's number confirmed. Every lane's published count already matches its own loop, which is why the mismatch can only exist in the merged tree.

One correction, measured. The trap reached me as "a wrong published count with nothing red", and the source of that reading is a paragraph in CONTRIBUTING.md claiming the merged tree goes green on "every existing check". That was true when written; it is not true now. Probed on this tree against the real binary, with a throwaway stand-in gate and the tree restored after — and the two ways to botch the resolution turn out to be caught by different gates, neither catching both:

botched how	the tree then has	red on
loop unioned, generator not re-run	loop 616, the eight sites 615	gatecountcheck (B), manifestcheck, readmedriftcheck (F2). deckclaimcheck passes — but the deck's three sites are three of the eight gatecountcheck owns, so not a hole
one side of the loop taken instead of the union	count self-consistent at 615, but a gate file present the loop never names	manifestcheck only — gatecountcheck passes, correctly, because the count really is consistent

So the count is fail-closed provided the full suite runs, which is why the pre-push suite is not negotiable. The second row is the one the old parenthetical was actually describing (member sets differing at the same count) and the one gatecountcheck structurally cannot see; that is now stated plainly instead of folded into a claim about every check. The paragraph also gains the step people skip (run the generator without --check) and the explicit warning never to trust the clean auto-merge of the three published files.

A stale claim that a defect is ungated costs more than the defect, because it sends people to rebuild a gate that already exists — which is what was about to happen here.

Full suite (head a4084a6d): gates=629 pass=627 skip=2 fail=0 wall=688.7s jobs=6 tree_writes=0. Doc-facing gates run individually first, all PASS: gatecountcheck, manifestcheck, readmedriftcheck, ripwirepubliccheck, docdriftcheck, planlintcheck, textdocscheck, mdsectioncheck.

Pins moved: none. This lane's count stays 615; it becomes 617 only in the merged tree, written by the generator.

Exclude --in=DIR from the shaping-family refusal.

honorsPaging() includes inDir, so validateShapingFlagsHonored() rejects explicit --top-k, --max-tokens, and --token-budget before the --rank-by=churn-decay --in=DIR contract can apply. The scoped contract preserves the map’s --top-k-dependent total and documents these shaping flags. Add the carve-out without removing inDir from honorsPaging(); paging validation must still apply when --limit or --offset is present.

Announcing before touching anything here — this lane and #217 overlap, and #217 merged to main at 0e3573af.

Overlap: README.md, docs/COMMANDS.md, src/cli.h, test/printf_parity.manifest.

What moved, so the resolution is mechanical rather than a read-through:

• README.md — the whole ## Reference guide section was rewritten in place (a claim-by-claim verification pass against a 0.6.0 build). Above the fold only four spots changed: the MSVC compiler line, two eighteen→seventeen skill counts, and two ./build/ripwire --help rows in the Documentation table. If your diff is above the fold, expect a small conflict; if it is in the guide, take main's side and re-apply your change on top.
• docs/COMMANDS.md — regenerated, and only two lines differ (the --replace-symbol-body summary). Do not hand-resolve it: merge main, then re-run python3 docs/docs_commands_build.py --bin build/ripwire.
• src/cli.h — one string changed: --replace-symbol-body's one-line summary now says it replaces a whole definition rather than a definition's body, which is what it actually does.
• test/printf_parity.manifest — docs(readme): the reference guide, verified against a 0.6.0 build #217 re-pinned help and help_all. This is the one that will bite: if this lane also re-pins those rows, resolving by picking a side ships a manifest that is green against neither binary, because the merged binary's help carries both changes. After merging main, re-run UPDATE_GOLDEN=1 bash test/printffmtparitycheck.sh and review the diff.

Also: #221 adds one entry to the top of CHANGELOG.md's [Unreleased]. Resolution there is a union of entries, never a choice between them.

Happy to do the merge-and-resolve on this branch if you would rather not — say so and I will; otherwise it is yours and I am not touching it.

[joyful-ii-V-I]

Update: the owner tells me an Opus session is working this lane, so disregard my earlier offer to resolve the conflicts — it is yours. The printf_parity and COMMANDS.md notes in that comment still apply when you merge main.

[joyful-ii-V-I]

Answering the outside-diff finding in review 5191130228 (src/cli.h:3473-3478, --in=DIR refused by the shaping-family guard): fixed on this branch at 837997f. --in is no longer a member of the verb paging set; the scoped block honours --limit/--offset on its own element, so validateShapingFlagsHonored no longer fires for --in alone. --max-tokens and --token-budget compose with --in (the emitted document is what is budgeted); --top-k=N and --top-k=0 each print exactly one refusal naming --in's own rule (the map is stubbed under --in, so a page size is meaningless there), and --help, docs/COMMANDS.md and the CHANGELOG list the refusal set exactly. recentscopecheck arm 6e asserts the distinctive text of that refusal and goes red without the guard.

refusal or failed-window result instead of blocking module initialization. Keep
the main capture-loop timeout behavior unchanged.

Inline comments:
In `@docs/captures/COMMANDS_showcase_2026-09-12.md`:
- Line 3386: The documentation comment’s description of would_show must use
definition-count wording rather than rendered symbol-row wording. Update the
would_show explanation in the captured command output to state that it counts
symbol definitions the same run would show without in=, then regenerate the
capture while preserving the surrounding contract.

In `@README.md`:
- Line 817: Update the README generated-reference totals to 173 unique long-flag
names and 163 “Try it” blocks, using the generator’s binary and showcase-capture
inputs rather than deck totals; run the docs_commands_build check and regenerate
COMMANDS.md only if it reports flag drift.

In `@src/main.cpp`:
- Around line 1211-1219: Update the disclosure call in churnDecayRanking so
discloseUniformChurnFallback is not emitted when stubbed is true; retain the
existing disclosure behavior for non-stubbed rankings and preserve the
zero-filled ranked.rank stub path.

In `@src/serialize.h`:
- Around line 1929-1931: Update the would_show legend text in the serializer and
compact legend to identify the hypothetical un-stubbed map’s top-K definition
count, replacing wording that refers to the run’s own shown= value. Keep the
existing distinctions from stubbed shown=0, row counts, and corpus totals
unchanged.

In `@test/recentscopecheck.sh`:
- Line 112: Update the pasteNext function’s subprocess.run invocation to enforce
a 60-second timeout, allowing TimeoutExpired to propagate so hung continuation
replays fail the regression job instead of blocking indefinitely.

🧹 Nitpick comments (1)

src/compactlegend.h (1)

401-402: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Correct the stale total= claim in this comment.

The comment states that the map stub carries total= on <symbols>. The emitter no longer does that: src/serialize.h writes <symbols stubbed="1" would_show="N" next="…"/>, and test/recentscopecheck.sh arm 5a2 fails if the stub carries total=, shown=, or capped=. The term text below already reads the correct attribute set, so only the comment is wrong. A maintainer reading it could re-add total= and red the gate.

📝 Proposed comment fix

-    // C1-b (2026-09-12): in=DIR — the scoped block (ELEMENT-qualified: scope= rides only a <recent>) and the map stub (total= on
-    // <symbols> alone; the paging window clause above already reads shown=/capped=). Both present-only.
+    // C1-b (2026-09-12): in=DIR — the scoped block (ELEMENT-qualified: scope= rides only a <recent>) and the map stub
+    // (stubbed=/would_show= on <symbols> alone; the stub borrows no paging attribute, so there is no total=/shown=/capped=
+    // to read there). Both present-only.
