Lane lane/agent-knowhow for 0.6.1. Six commits (plus two merges of main). The owner's framing for this round: "for this to work the whole
system needs to be put together — the answers need shortening/optimizing but the agent actually needs to
know how to use it."

2026-09-13: a review of this PR found eight defects in it, every one reproduced against this lane's own
binary before it was fixed. They are all fixed here, each with an arm; the review round has its own section
below, and the three claims the review withdrew are corrected in place in the text above it rather than left
standing.

The defects

  1. The task router could not reach the recency question at all. what changed recently in DIR, who touched this lately, the newest commits here — every phrasing abstains with score="0" on
    origin/main's binary, so --rank-by=churn-decay (and the --in=DIR scope landing beside it) is
    unreachable from a task said in words. One correction to the brief, with the evidence.
    PLAN_OUTPUT_ROUTING_LOOP_2026-09-12_REPORTS/08_owner_calls_BRIEF.md §3 cites taskroute.h:136
    ("recent is a stop-word") as the cause. That line is real — recent is in kWeakSymbolStopWords
    but that list governs symbol resolution only: it is why --expand='recent' can never be minted out
    of prose, and it has never had any bearing on which INTENT a task reads as. The cause is simply that no
    churn/recency intent existed. Nothing was taken off the stop list (those words must still never name a
    definition); they became intent evidence instead, which is exactly what the list's own comment says
    they are. Recorded in the source beside the new route, so the next reader does not re-derive it.
  2. The widening page was discoverable only from a thin answer. forpage.h's next= names
    --for=TASK --limit=N — but only after serving a thin answer, which is one call too late for an agent
    choosing what to run FIRST, and the first call is what --help-task exists to pick.
  3. No new shape of this release was named where an agent reads. Measured on main's skills: of the
    shapes already in the binary, --for's --limit/--offset page and its coverage= gauge appear in
    no skill body and no wrap primer within reach of the verb they belong to. --limit is named (paging a
    high-cardinality verb) and --for is named — in different files. Naming the two apart does not tell
    anyone the page exists; the PAIR is the instruction.

The change

1. recency-window (src/taskroute.h, src/cli.h, src/main.cpp). ripwire <dir> --help-task="what changed recently in db"ripwire <dir> --rank-by=churn-decay [--in=db], under
ripwire-fresh-eyes. CONJUNCTIVE in three parts, because two are not enough: a TIME word, a MOTION word,
and a word naming the corpus (or a directory of it the task named). A time word alone is usually part of
a compound noun (the decoy the brief names, the recent-file cache); a time word plus a motion word is
also a sentence about a supplier revising their terms last quarter. An EXPLANATORY question is never this
route however many of the three it holds. Single-word cues are matched WORD-BOUNDED (review finding 1),
and multi-word phrases carry their own boundaries. The route runs LAST, only when the weighted tier named
nothing
(review finding 2) — that placement is both the argument that it costs the older routes nothing
and how it reads a dirty worktree: on a dirty tree is my diff safe to merge, i changed these files recently is still review-diff's question, and review-diff (dirty-only by its own wording) wins before
this route is reached.

--in=DIR is composed only when both halves hold. The task must name a directory of the CORPUS in a
locating slot (the same cue discipline the symbol slot uses, matched on sarif::rootRelativeUri — the
one root-relative spelling the map's p= and --in= both use), and the running build must ship the
flag
: cli.h's new shipsViewFlag reads the flag table itself. A router that composes a flag its own
parser has no row for hands back a command that exits non-zero on the first paste — the prerequisite
violation this file refuses from every other direction (a plan path that is not there, a reaches claim
the --verify parser rejects). --in= lands in #212; this build has no row for it, composes none,
and gains the scope with no further edit here. When the task names a directory this build cannot scope
to, the reason= says so
(review finding 7) instead of handing back a whole-repository answer to a
question about one directory with nothing marking the drop. The directory walk is the shared
slotCandidate EARLIEST-match walk, so what changed lately across storage, but only in the release notes
reads the first slot in the sentence rather than whichever cue sits earlier in an array.

2. The widening step on the FIRST call. Every --for-shaped recommendation carries
next="… --limit=40" on its <choice>keyed off the INTENT (kForShapedIntents), never off finding
the flag in the command, and spelled by forpage.h's own forWidenNext, so the recommendation's
follow-up and the answer's own follow-up are one spelling under one 120-byte ceiling (review finding 3).
Present-only: a recommendation that is not --for-shaped carries no attribute at all.

3. The --help-task document gains the LEGEND it never had in the default dialect (review finding 4):
every attribute a reader met on its only screen was undefined, with the compact layer's present-only legend
the only place any of them was explained. One line defines all twelve plus <run>, ending in the shared
kNextLegendClause; --help-task joins legendcoveragecheck's enumeration and nextverbcheck's
population.

4. The shapes are named where an agent reads — one or two sentences each, no frontmatter touched:
ripwire-fresh-eyes gains pass 1a (the history question: --rank-by=churn-decay, --in=DIR and what it
does to the map, merge_bombs_skipped= read as the disclosure it is, scope=); ripwire-orient §2 gains
the thin-answer rule (coverage=, and that the step after a thin answer is --for=TASK --limit=40, not a
body) and how to compose a selector out of a row whose identity is sc= (p::sc::n);
map-before-you-read gains the same in its pagination row (on --for a --limit is not a cut but a
wider net, and the bundle-shaping flags are refused beside it); ripwire-change-check gains the grouped
<g hops= n= p= run_unknown="1"/> row beside --affected, with the invariant it preserves.

5. test/agentsurfacecheck.sh (new). Two arms:

  • (A) a RATCHET over all 163 long flags --help advertises: each is named in a skill body or the
    ripwire wrap primer, or recorded in test/agentsurfacefix/unnamed_flags_baseline.txt with the reason
    it is still a gap (5 lines today: --eval-skills, --eval-stray, --pin-census, --max-file-size,
    --sarif). The floor may only be edited DOWNWARD, and the arm ALSO fails when a recorded line is no
    longer a gap, so a closure cannot be filed and forgotten. A flag added with no agent surface goes red in
    the commit that adds it. The match is WORD-BOUNDED (review finding 5): 23 advertised flags are a
    strict prefix of another (--in inside --index-out, --not inside --notes, --for inside
    --format), and a substring test would report every one of them as named by its longer sibling — the arm
    prints that count, so the population the bounded match protects is visible.
  • (B) this round's new shapes — the term AND its verb within five lines of one another on one surface.
    Each row is PROBED by RUNNING the verb (review finding 5: --help advertising a flag is not evidence
    that the flag emits anything, and the --limit=/--offset= rows had only asked --help), and TERM
    (what the binary emits, <g) is split from SURFACE_TERM (what a skill must spell, <g ) so
    <graph-query cannot satisfy a row about grouped test rows. A shape that has not landed is declared on
    the PENDING list with the lane that ships it, and the gate is SELF-HEALING on arrival: a pending shape
    that shows up in the binary with its pairing already satisfied PASSES, so the lane that ships it never has
    to edit this file. What stays red is the dishonest direction — a surface promising a shape this build
    refuses with no lane declared. The arm asserts its own population (8 of 8 rows probed), against the
    harness-reports-success-for-work-it-skipped trap. All five pending shapes (--in=, sc=, <g,
    merge_bombs_skipped=, scope=) are already paired on a surface here, so feat(churn): --in=DIR scopes recent changes to a directory, and the window discloses the merge bombs it skipped #212/perf(testmap): tests-to-run rows without a runner are grouped by hop distance, the disclosure once per group #214/perf(output): short symbol ids on maps, a present-only compact legend on --for, and compact by default on agent surfaces #215 turn those rows
    green without touching a skill.

docs/COMMANDS.md is deliberately NOT an accepted surface, and this is the one place the brief's
instruction was not followed literally: it names every flag by construction (and its recorded captures
contain every attribute), so accepting it would make this gate one that cannot fail. It is the reference,
not the file an agent loads mid-task.

Coverage at this head: 0.917 test, 0.933 dev, 0.925 all. Every miss is an abstentionharmful=0.000
and precision=1.000 on all three splits, and the confusion rows are want=… got=abstain only.

The control: this head's binary scores the pre-lane 225 rows 0.939 / 0.946 / 0.942 — the same three
numbers, with the same coverage (0.907 / 0.929 / 0.918), so no inherited row moved.

A claim WITHDRAWN by the review (finding 2). An earlier revision of this body said the 225 pre-existing
rows are byte-identical on (status, intent) across the new route, and offered that as evidence the route
steals no answer. It is true and it is nearly vacuous: measured, 0 of those 225 prompts reach the recency
route at all
— they fail one of the three conjuncts, or an earlier route answers first — so the identity
was never in question. A number that cannot move is not a measurement. The evidence that the route steals
nothing is the corpus's own negatives and the gate's arms. test/taskroutefix/PROVENANCE.md records the
withdrawal.

24 rows added by this lane (225 → 249): 14 in the first round (10 positives, 4 of them naming a
directory, and 4 decoys) and 8 in the review round — four NEGATIVES, one per word-boundary class the
review found (here in where/there, source in outsource, file in profile, code in codec); one for the
dirty WORKING TREE; and three POSITIVES for vocabulary that abstained (a verb below the motion floor,
since <a day or a date>, and what is new in DIR). Split by the committed content-hash rule. Two of the
eight are labelled instrumented-cli rather than handwritten, by the rule the corpus's 2026-09-10 section
states: their trigger is a small closed phrase list, so a sentence that routes necessarily reuses one of its
phrases. Two more rows came with the second review round (below).

A second claim corrected. An earlier revision of this body, following
test/taskroutefix/PROVENANCE.md, said the contamination screen was down to 1 flagged line from 2.
That does not reproduce. Measured with one binary at three points — 5e1ae383 (the commit before this
lane), the first review round's own seal, and this head — the screen reports the same 2 flagged lines
every time
: 61 (i change its, against the card literal did I change its contract?) and 176 (the value of, against the variable-slot cue). Neither is a row this lane wrote; the count never moved. The
correction is recorded in PROVENANCE.md beside the claim.

Seal at this head: sha256(prompts.tsv) = bb802dabd45bf228b51296cca2a0f35c54824895f429954959ef7219416d0f30
(rows=249, dev=119, test=130), reproduced on a fresh build of this head.

Review round — 2026-09-13, eight findings

Each was reproduced against this lane's own binary before it was fixed, and each is now an arm.
test/taskroutecheck.sh gains 20.

  1. Word boundaries. The three conjuncts scored cues by substring, and four corpus cues live inside
    ordinary words — so our supplier changed their terms recently, where is that noted?, the
    counter-example this route's own comment is built on, recommended the churn window at
    confidence="high". phraseScore and its word-bounded twin are ONE scorer with the match mode as a
    parameter (CueMatch), since that is the only thing the two spellings differ in.
  2. The working tree. The route ran BEFORE the weighted tier and never read dirty, contradicting this
    file's own comment and the CHANGELOG. It runs last now. (And the byte-identity claim above is withdrawn.)
  3. The widening next=. Keyed off finding --for= anywhere in the COMMAND, so
    plan the new feature: replace the --for= flag scoring — where the flag sits inside another verb's
    quoted argument — handed --pack-task a page width it refuses (measured: exit 1). Keyed off the INTENT
    now, and it re-implemented forWidenNext (its own quoting, no ceiling, 197–236 B where every other
    next= stops at 120); it calls the shared one, so the task text is no longer emitted twice at full
    length.
  4. The legend. next= rode a document with no legend at all in the default dialect.
  5. The surface gate, both directions — probe by running the verb, TERM vs SURFACE_TERM, word-bounded
    flag matching, an asserted population, and self-healing on arrival. Verified with a shim that makes all
    five pending shapes present: 8 of 8 rows flip to "is named beside", ALL PASS, no gate edit.
  6. Vocabulary. landed/merged/commit/moving/activity/updated sat below the motion floor and
    there was no since <date> or new in reading, so what landed in storage this week,
    commits since Monday under storage and what is new in the storage directory all abstained. since
    takes git's own vocabulary structurally (a weekday, a month or a digit after it); what is new in DIR is
    recognised as the phrase it is rather than by giving new a weight in two tables.
  7. A dropped scope is disclosed, and the directory walk takes the EARLIEST slot, not the earliest cue in
    the array — one walk, one filler table, shared with the variable reader that already had the rule.
  8. cli.h includes <algorithm> and <ranges> for its own any_of.

Second review round — CodeRabbit on aaa3baa6, one Major finding

The defect. The round above bounded the SINGLE-word cues and left the multi-word ones on substring
matching, on the reasoning that "a phrase carries its own boundaries". A phrase delimits its own INTERIOR
and nothing at its two ends: the first word of how do can finish another word and the last can begin one.
show documentation contains how do; show issues contains how is. Both of those are questions about
this repository's history, and both tripped the EXPLANATORY guard and abstained at score="0".

The reported repro did not reproduce, and the real one is narrower. The finding cited
what changed recently in the documentation directory, on the reading that how do is a prefix of
documentation. It is not — no cue is a substring of that word, and that prompt already routed
recency-window on the unfixed binary. The false positive needs the cue to SPAN two words: a word ending
in how/what followed by one beginning do/is/are/does. The finding is real; only its example was
wrong, and the arms assert the real shape.

The fix, scoped as the finding asked: the six cues are a named table (kExplanatoryCues) matched with
boundedFind — the spelling every other cue in this file already uses — and phraseScore keeps substring
semantics for the multi-word router phrases. The CueMatch comment no longer claims a phrase carries its
own boundaries; it says Substring is for cues whose first and last words do not finish or begin ordinary
words, and that a caller who cannot say that of its own cues asks for WordBounded.

Arms: test/taskroutecheck.sh +3 — the two cross-word positives (RED against the unfixed binary,
status="abstain" score="0") and the control they may not be bought at the price of,
how do i see the files in storage that changed recently, which must still abstain and does, before and
after. Corpus: +2 rows, both test by the content-hash rule. The positive names storage, which the
eval fixture holds, so the directory half is exercised: on a build whose flag table ships --in= that is
--in=storage; this build has no such row and composes none, which is why the row asserts the intent while
the existing caps-gated gate arm asserts the flag.

Gates

Red first, test/taskroutecheck.sh (11 arms in the first round, 20 more in the review round). Against
the pre-change binary of the first round, 4 FAIL:

  FAIL  recency route wrong: <task-route status="abstain" … score="0" …>
  FAIL  who-touched recency route wrong: <task-route status="abstain" … score="0" …>
  FAIL  locate-task carries no widening next=: …<choice intent="locate-task" … score="15"><run>…</run>
  FAIL  no next= recovered from the locate-task recommendation

Green here, ALL PASS. The emitted commands are EXECUTED, not just matched (the bare recency command
returns a <recent> block; the widening next= is unquoted with shlex and returns the <files> page).
route() reads every arm off the COMMENT-STRIPPED body, so a legend that names an attribute can never
satisfy an assertion about a row carrying one; routehookcheck R6 counts <run> in the body for the same
reason.

Red first, test/agentsurfacecheck.sh. Against main's skills and this binary, 3 FAIL:

  FAIL  (B) no skill body or wrap primer names --limit= within five lines of --for — the file-grain widening page is unreachable from a skill
  FAIL  (B) no skill body or wrap primer names --offset= within five lines of --for — the widening page continuation is unreachable from a skill
  FAIL  (B) no skill body or wrap primer names coverage= within five lines of --for — the thin-answer coverage gauge is unreachable from a skill

Green after the four skill edits. Arm (A) was already green and is the guard that keeps it so.

Full suite, foreground (python3 test/pargates.py . ./build/ripwire -j 6), run at all three heads —
the first review round, the merge of origin/main (#221's CHANGELOG entry), and the second review round:

a2e26426   gates=628 pass=626 skip=2 fail=0 wall=1124.4s jobs=6 tree_writes=0
aaa3baa6   gates=628 pass=625 skip=2 fail=1 wall=1614.0s jobs=6 tree_writes=0
342d16d9   gates=628 pass=626 skip=2 fail=0 wall=1258.9s jobs=6 tree_writes=0

The two skips are the environmental pair (argvdiffcheck and editchecknotecheck, both wanting a
RIPWIRE_BASE* reference binary). The second run's single failure is strkerncheck rc=124 — a TIMEOUT
at its declared 300 s budget, not an assertion
: that run was 490 s slower end to end on a busier machine,
and the gate's slowest arm is an x86_64/AVX2 mirror under Rosetta 2. Re-run alone at the same head it
PASSES in 170 s
, all 26 assertions plus the mutation control (3c control: … rc=1 — a red, classified as a red). Nothing in this lane touches src/strkern.h; the merge that preceded the run changed
CHANGELOG.md only. The third run, at the head this PR now carries, is clean with no re-run.

--quality-delta at 342d16d9: gating="0", no ack, one sev="minor" row —
short-horizon-churn on recencyTaskChoice, churn="self", the honest consequence of fixing that one
function three times in a day.

ASan (-DRIPWIRE_ASAN=ON, LSAN_OPTIONS=suppressions=lsan_suppressions.txt): routed tasks and the
taskroutecheck and agentsurfacecheck fixtures under asan/ripwire — exit 0, zero sanitizer lines.
Determinism (--help-task twice, byte-identical) and xmllint --noout on the routed document.

--quality-delta gating="0" at this head, no ack: gating="0" acked="0" minor="0", no regression
row of any kind. Five gating rows the review round would otherwise have raised were fixed by REUSE rather
than acked — phraseScore/wordScore became one scorer, four hand-written any_of membership tests became
isOneOf, and the three one-line call-through wrappers the shared helpers left behind were folded into
their single call sites.

Pins moved

  • test/regression.sh gate loop + the generated count: 613 → 614 (docs/gatecount_build.py, 8 marked
    sites in 3 files), from the first round's new gate file; the review round adds arms to existing gates and
    moves the count no further. docs/limits_build.py --check clean; no cap changed value.
  • test/taskroutefix/prompts.tsv seal re-recorded in PROVENANCE.md twice (rows 225 → 239 → 247,
    dev 111 → 118 → 119, test 114 → 121 → 128).
  • A legend pin DID move, contrary to what an earlier revision of this body said. --help-task now
    carries a legend and joins legendcoveragecheck's enumeration (ALL PASS, no new baseline debt) and
    nextverbcheck's population. No --help row changed, so docs/COMMANDS.md needed no regeneration
    (docscommandscheck ALL PASS).

Depends on, and what is deliberately NOT in this PR yet

--in=DIR ships in #212, the grouped <g row in #214, and sc=/the compact-legend posture on
agent surfaces in #215. Nothing here waits for them: the router composes --in= only on a build whose
flag table has it (and says so in reason= when it cannot), and the new gate's pending rows assert nothing
until the shape arrives — then require the pairing this PR already wrote, and pass on arrival with no edit.
agentsurfacecheck covers what main has, which is the honest scope for a PR based on main.

Three edits are held for a follow-up commit on this PR, once #215 merges, because #215 owns those
exact lines and this lane must not fork them:

  1. the ripwire-router skill's moment→skill row for the recency question (that file is rewritten by perf(output): short symbol ids on maps, a present-only compact legend on --for, and compact by default on agent surfaces #215);
  2. the --legend=compact / --legend=full escape-hatch sentence, in the router skill and in src/wrap.h's
    primer — added only if perf(output): short symbol ids on maps, a present-only compact legend on --for, and compact by default on agent surfaces #215 has not already said it (its blurb sits at the ceiling of wrapverbscheck's
    10–20 line band, so a line added there has to displace one);
  3. --legend=compact on the two commands this PR adds to skill bodies that perf(output): short symbol ids on maps, a present-only compact legend on --for, and compact by default on agent surfaces #215's new
    skilltruthcheck policy arm will require it on (--help-task in ripwire-fresh-eyes; the --for
    command stays exempt by that same policy).

…ed no widening step

THE DEFECTS. Two, both in src/taskroute.h, both measured as abstentions rather than
guessed at:

1. No churn or recency intent existed at all. `what changed recently in DIR`, `who
   touched this lately`, `the newest commits here` — every phrasing abstained with
   score="0" against origin/main's binary, so --rank-by=churn-decay (and the --in=DIR
   scope this release adds beside it) was unreachable from a task said in words. The
   order that asked for this route blamed the weak-symbol stop list, and that is worth
   correcting where the next reader will look: kWeakSymbolStopWords governs SYMBOL
   RESOLUTION only — it is why --expand can never be handed one of those words out of
   prose — and it has never had any bearing on which INTENT a task reads as. Nothing was
   taken off that list; those words became intent evidence, which is what its own comment
   already said they are.
2. The file-grain widening page (--for=TASK --limit=N, forpage.h) was named only by a
   thin ANSWER's own next=. That is one call too late for an agent choosing what to run
   FIRST, and the first call is what --help-task exists to pick.

THE CHANGE.

- `recency-window` → `ripwire <dir> --rank-by=churn-decay`, under ripwire-fresh-eyes.
  CONJUNCTIVE in three parts, because two are not enough: a TIME word, a MOTION word,
  and a word naming the corpus (or a directory of it the task named). A time word alone
  is a compound noun; a time word plus a motion word is also a sentence about a
  supplier's terms last quarter. An EXPLANATORY question is never this route however
  many of all three it holds, and the working tree stays --situ's question: the
  dirty-worktree review-diff arm is unchanged.
- `--in=DIR` is composed only when the task names a directory of the CORPUS in a
  locating slot (the same cue discipline the symbol slot uses) AND the build ships the
  flag. The second half is cli.h's new shipsViewFlag, reading the flag table itself: a
  router that composes a flag its own parser has no row for recommends a command that
  exits non-zero on the first paste, which is the prerequisite violation this file
  refuses from every other direction. --in= lands in the recency-scope lane; this build
  has no row for it, composes none, and gains the scope with no further edit here.
- Every --for-shaped recommendation now carries next="… --limit=40", derived from the
  COMMAND rather than the intent id so a route added later cannot forget it, and
  present-only: a choice with nothing to widen carries no attribute.

MEASURED (bench/taskroute_eval.py, same corpus, only the binary changed):

  split | rows      | accuracy      | precision | harmful | neg-spec | coverage
  test  | 114 → 121 | 0.939 → 0.942 | 1.000     | 0.000   | 1.000    | 0.907 → 0.914
  dev   | 111 → 118 | 0.946 → 0.949 | 1.000     | 0.000   | 1.000    | 0.929 → 0.932
  all   | 225 → 239 | 0.942 → 0.946 | 1.000     | 0.000   | 1.000    | 0.918 → 0.923

The 225 pre-existing rows are byte-identical on (status, intent) — they score the same
three numbers with the same confusion rows on the new binary, which is what placing the
route BELOW every older reading was for. All 14 added rows are correct, so the deltas are
arithmetic on a larger denominator, not a re-ranking. Corpus: 10 positives (4 naming a
directory) + 4 decoys, one per class the three conjuncts refuse; splits by the committed
content-hash rule; the contamination screen is unchanged at its 2 pre-existing flagged
lines (test/taskroutefix/PROVENANCE.md records the two authoring rules that kept it
there).

GATE, RED FIRST. test/taskroutecheck.sh gains 11 arms. Against the pre-change binary:
4 FAIL — `recency route wrong: status="abstain"`, `who-touched recency route wrong:
status="abstain"`, `locate-task carries no widening next=`, `no next= recovered from the
locate-task recommendation`. Green here, ALL PASS. The directory arm asserts BOTH
directions against the shipped flag table, so it is a real assertion on a build with
--in= and on a build without it; the emitted commands are executed, not just matched.

ALL PASS, plain build and asan/ripwire alike: taskroutecheck, compactroutecheck,
routehookcheck, codexpromptroutecheck, toolcallroutecheck, routecheck, routeoncecheck,
nextverbcheck, forwidencheck, clicheck, flagtablecheck, flagsurfacecheck, helpbudgetcheck,
printffmtparitycheck, docscommandscheck, xmlwellformed. --help-task output is
byte-identical across runs and xmllint-clean; ASan/UBSan (LSan suppressions) reports
nothing on four routed tasks or on the gate's whole fixture.

--quality-delta gating="0", no ack. The first cut of shipsViewFlag was a ninth hand-rolled
linear scan and took ten gating rows (duplication + new-clone-of-reused-helper against
eight existing predicates); it is one std::ranges::any_of now. directorySlotCandidate's
first cut hit ccx 36 / nest 5 and is three functions.

…d now a gate says so

THE DEFECT. 0.6.1 adds four surfaces an agent has to ASK for — a directory-scoped recency
window, a file-grain widening page, grouped tests-to-run rows, short symbol ids — and not
one of them was named on any surface an agent LOADS. Measured on origin/main's skills:
of the shapes already in the binary, --for's `--limit`/`--offset` widening page and its
`coverage=` gauge appear in no skill body and no wrap primer within reach of the verb they
belong to. `--limit` is named (paging a high-cardinality verb) and `--for` is named, in
different files: naming the two apart does not tell anyone the page exists. The PAIR is the
instruction.

THE CHANGE, one or two sentences per surface, no frontmatter touched:

- ripwire-fresh-eyes gains pass 1a, the HISTORY question: --rank-by=churn-decay, the
  --in=DIR scope and what it does to the map, merge_bombs_skipped= read as the disclosure
  it is (if the commit you are hunting is a giant rename it is in that N, not in the rows),
  and the --help-task phrasing that routes there.
- ripwire-orient §2 gains the thin-answer rule: what coverage= is, when it rides the root,
  and that the step after a thin answer is --for=TASK --limit=40, not a body. Plus how to
  compose a selector out of a row whose identity is sc= (the id is p::sc::n).
- map-before-you-read gains the same in its pagination row, because on --for a --limit is
  not a cut but a wider net — and the bundle-shaping flags are refused beside it.
- ripwire-change-check gains the grouped <g hops= n= p= run_unknown="1"/> row beside
  --affected, with the invariant it preserves: every path still listed verbatim, a row
  carries run= or run_unknown="1", never neither.

THE GATE (test/agentsurfacecheck.sh, new, listed in test/regression.sh, gate count
regenerated 613 → 614). Two arms, two questions:

(A) A RATCHET over all 163 long flags --help advertises: each is named in a skill body or
    the wrap primer, or recorded in test/agentsurfacefix/unnamed_flags_baseline.txt with
    the reason it is still a gap (5 lines today: two eval harnesses, --pin-census,
    --max-file-size, --sarif). The floor may only be edited DOWNWARD, and the arm also
    fails when a recorded line is no longer a gap, so a closure cannot be filed and
    forgotten. A flag added with no agent surface goes red in the commit that adds it.
(B) THE ROUND'S NEW SHAPES: --in=, --limit=/--offset= on --for, coverage=, sc=, <g,
    merge_bombs_skipped=, scope= — the term AND its verb within five lines of one another
    on one surface. Each row is PROBED against the binary first, because a surface may not
    promise what this build cannot parse: a shape that has not landed yet is reported with
    the lane that ships it and asserts nothing, and the pending list FAILS the moment the
    binary has the shape, so it cannot outlive its reason. All five pending shapes are
    already paired here, so those lanes turn the arm green without touching a skill.

docs/COMMANDS.md is deliberately NOT an accepted surface: it names every flag by
construction, so accepting it would make this gate one that cannot fail. It is the
reference, not the thing an agent loads mid-task.

RED FIRST, against main's skills and this binary: three FAIL rows — "no skill body or wrap
primer names --limit= within five lines of --for", the same for --offset= and for
coverage=. Green after the four skill edits; arm A was already green and is the guard
that keeps it that way.

ALL PASS: agentsurfacecheck (plain and asan), skilltruthcheck, skilldescbudgetcheck,
skillevalcheck, skillinstallcheck, skillscanreadcheck, skillroutingjudgedcheck,
wrapverbscheck, hookcheck, manifestcheck, gatecountcheck, limitstablecheck,
shellgateindexcheck, readmedriftcheck, deckcheck, deckclaimcheck, ripwirepubliccheck,
utf8scrubcheck. Generators: gatecount_build.py --check (614 in 8 sites, 3 files),
limits_build.py --check clean.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…probing for

A PRESENT-ONLY probe that can never observe its shape is a row that says "not in this
build yet" forever, and the pending list it parks on would then outlive its reason without
the gate noticing — the failure this gate's own header warns about, landing on the gate.

- `<g ` (trailing space) was probed against `--affected`, where on a tree whose harnesses
  all HAVE a runner nothing groups and the only place the shape appears is the legend
  clause that defines it — which spells `<g>`, not `<g `. The term is `<g` now, and the
  probe pattern with it, so the row goes present when either the grouped row or its
  definition is in the document. `grep -c '<g'` on this build's `--affected` output is 0,
  so the probe still cannot pass by accident.
- `scope=` was probed with a bare `--rank-by=churn-decay`, and the scoped block only
  exists when `--in=` is passed: after the scope lands, that probe would still report the
  attribute absent. The probe passes `--in=src` now — refused (absent) on a build with no
  such flag, present on the build that has it.

Both rows still report "not in this build yet" here, which is the honest reading; the
pairing they will require is already on a surface (skills/ripwire-fresh-eyes,
skills/ripwire-change-check), so the lanes that ship the shapes turn them green.
agentsurfacecheck ALL PASS.

Changes

Task routing and agent surfaces

Layer / File(s) Summary
Recency routing and shared matching
src/taskroute.h
The router adds a recency-window route for repository-history questions. It uses word-bounded cues, validates directory scope, and runs after weighted candidates.
CLI capability and route output
src/cli.h, src/main.cpp
The CLI detects whether --in=DIR is shipped. --help-task passes this capability to the router, emits an XML legend, and adds next= only for selected intents.
Fixtures and routing validation
bench/taskroute_eval.py, test/taskroutecheck.sh, test/taskroutefix/PROVENANCE.md, test/legendcoveragecheck.sh, test/nextverbcheck.sh, test/routehookcheck.sh
Fixtures and tests cover directory routing, precedence, word-boundary cases, widening commands, legends, and required flags.
Agent-surface gate and guidance
test/agentsurfacecheck.sh, test/agentsurfacefix/unnamed_flags_baseline.txt, skills/*
A new gate checks bounded flag coverage and output-shape terminology. Skill documentation describes grouped rows, selectors, recency output, and file-grain widening.
Release and gate records
CHANGELOG.md, README.md, docs/EVALS.md, present/deck5_ripwire_build.js, test/regression.sh
Documentation records the routing and CLI changes. Gate-count references change from 613 to 614, and declinedlistcheck joins the regression loop.

Comment thread test/agentsurfacecheck.sh Outdated
joyful-ii-V-I and others added 3 commits September 13, 2026 13:40
… and outranked the diff question

The 2026-09-13 review of #218, eight findings, each reproduced against this lane's own binary before it
was fixed. Every one is now an arm.

1. WORD BOUNDARIES. The three conjuncts were scored with substring matching, and four of the corpus cues
   live inside ordinary words: `here` in where/there/adhere, `source` in outsource, `file` in profile,
   `code` in codec. So `our supplier changed their terms recently, where is that noted?` — the
   counter-example this route's own comment is built on — recommended the churn window at
   confidence="high". phraseScore and its new word-bounded twin are ONE scorer with the match mode as a
   parameter (CueMatch), because that is the only thing the two spellings differ in; the single-word time,
   motion and corpus cues are bounded, the multi-word phrases carry their own boundaries. Four negatives
   added to the corpus, one per cue.

2. THE WORKING TREE. The route ran BEFORE the weighted tier and never read `dirty`, so on a dirty tree
   `is my diff safe to merge, i changed these files recently` routed to the churn window instead of
   --situ — contradicting this file's own comment and the CHANGELOG. It runs LAST now, only when the
   weighted tier named nothing, which is where the dirty-only review route lives: review-diff wins there,
   and on a clean tree the same sentence has no diff to review. A dirty row is in the corpus.
   Also withdrawn: the claim that 225 pre-existing rows are byte-identical across this route. Measured, 0
   of those 225 reach it at all, so the identity was never in question. PROVENANCE.md says so.

3. THE WIDENING next=. It was keyed off finding "--for=" anywhere in the COMMAND — including inside
   another verb's quoted task text, so `plan the new feature: replace the --for= flag scoring` handed
   --pack-task a page width it refuses (exit 1). Keyed off the INTENT now (kForShapedIntents). It also
   re-implemented forpage.h's forWidenNext: its own quoting, and no ceiling — 197-236 B where every other
   next= stops at 120 and emits nothing rather than a hint that pastes wrong. It calls forWidenNext now,
   so the recommendation's follow-up and the answer's own follow-up are one spelling, and the task text is
   no longer emitted twice at full length. --help-task joins nextverbcheck's population.

4. THE LEGEND. next= rode a document with no legend at all in the default dialect — every attribute on its
   only screen undefined, the compact layer's present-only legend the only place any of them was
   explained. One line now defines all twelve plus <run>, ending in the shared kNextLegendClause;
   --help-task joins legendcoveragecheck's enumeration (ALL PASS, no new baseline debt).

5. THE SURFACE GATE, both directions. agentsurfacecheck now: probes by RUNNING the verb (a --help mention
   is not evidence that a flag emits anything — the --limit=/--offset= rows only asked --help); splits
   TERM (what the binary emits, `<g`) from SURFACE_TERM (what a skill must spell, `<g `) so `<graph-query`
   cannot satisfy a row about grouped test rows; matches flags WORD-BOUNDED in the ratchet (23 advertised
   flags are a strict prefix of another — --in inside --index-out, --not inside --notes — and the arm
   prints that count); asserts its own population (8 of 8 rows probed); and is SELF-HEALING: a declared
   pending shape that arrives with its pairing already satisfied PASSES. Verified with a shim that makes
   all five pending shapes present: 8 of 8 rows flip to "is named beside", ALL PASS, no gate edit.

6. VOCABULARY. landed/merged/commit/moving/activity/updated sat below the motion floor and there was no
   `since <date>` or `new in` reading, so `what landed in storage this week`, `commits since Monday under
   storage` and `what is new in the storage directory` all abstained. The six verbs are at the floor (the
   corpus conjunct is what makes that safe), `since` takes git's own vocabulary structurally (a weekday, a
   month or a digit after it), and `what is new in DIR` is recognised as the phrase it is rather than by
   giving `new` a weight in two tables. Three positives added.

7. A DROPPED SCOPE IS DISCLOSED. When the build has no scope flag the recognised directory was dropped
   silently and a whole-repository answer came back to a question about one directory; the reason says so
   now. And the directory walk took cues in ARRAY order, so `what changed lately across storage, but only
   in the release notes` could read the later slot: it is variableSlotCandidate's EARLIEST-match walk now,
   shared — one walk, one filler table, a normalizer and a predicate per caller.

8. cli.h includes <algorithm> and <ranges> for its own any_of.

MEASURED (bench/taskroute_eval.py, 247 rows: the committed 225 plus this round's 22):

  split | rows | accuracy      | precision | harmful | neg-spec | coverage
  test  | 128  | 0.939 → 0.945 | 1.000     | 0.000   | 1.000    | 0.917
  dev   | 119  | 0.946 → 0.950 | 1.000     | 0.000   | 1.000    | 0.933
  all   | 247  | 0.942 → 0.947 | 1.000     | 0.000   | 1.000    | 0.925

The original 225 score 0.939 / 0.946 / 0.942 on this binary, unchanged. Contamination screen: 1 flagged
line (176, pre-existing), DOWN from 2 — two rows whose trigger is a closed phrase list are labelled
instrumented-cli by the rule the 2026-09-10 section states.

GATES. taskroutecheck gains 20 arms (the four substring decoys, the dirty-tree arm, the three vocabulary
rows, the earliest-slot arm, the quoted-flag arm, the ceiling arms, the twelve legend arms); route() reads
every arm off the comment-stripped body, so a legend that names an attribute can never satisfy an
assertion about a row carrying one. routehookcheck R6 counts <run> in the body for the same reason.
ALL PASS, plain build and asan alike: taskroutecheck, agentsurfacecheck, nextverbcheck,
legendcoveragecheck, routehookcheck, compactroutecheck, codexpromptroutecheck, toolcallroutecheck,
routecheck, compactlegendcheck, legendcostcheck, printffmtparitycheck, docscommandscheck, clicheck,
flagtablecheck, helpbudgetcheck, skilltruthcheck, wrapverbscheck, gateexitcheck, manifestcheck,
gatecountcheck, limitstablecheck, readmedriftcheck, xmlwellformed. Determinism and xmllint on the routed
document; ASan/UBSan clean on five routed tasks and on all three gates' fixtures.

--quality-delta gating="0", NO ack. Five gating rows were fixed by reuse, not acked: phraseScore/wordScore
became one scorer, four hand-written any_of membership tests became isOneOf, and the three one-line
call-through wrappers the shared helpers left behind (isSlotFiller, isForShapedIntent,
directorySlotCandidate) were folded into their single call sites.

Both sides add a section under [Unreleased] and neither replaces the other: this lane's
recency-route entry and #221's reference-guide verification pass are both kept, whole, in
that order. CHANGELOG.md is the only file either side touched.

Landing this for 0.6.1 now, on the owner's call — announcing first because the shared joyful-ii-V-I identity means I cannot tell from the branch whose session this is.

Your entry is already written into the 0.6.1 changelog draft, so this lane is in the release section either way; merging it makes the section true.

If you are the session preparing the release: main is moving under you right now. I am landing #214, #218 and #219, then resolving #212 and #215's conflicts, and only then assembling the ## [0.6.1] section from the draft. Do not tag until that section matches what actually landed — the owner has asked for the release PR to be prepared but left unmerged for their review.

Shout here if this lane is mid-edit and I should hold off.

Correction to my previous comment — disregard it. The owner tells me an Opus session is actively working #212, #214, #215 and #218, which need tests and a push. I am not landing anything here and I am not touching #212/#215's conflicts. This lane is yours.

The one part of that comment still worth keeping, because it will bite whoever merges main into this branch: #217 re-pinned help and help_all in test/printf_parity.manifest. If this lane re-pins the same rows, do not resolve by choosing a side — the merged binary's help carries both changes, so its hash is neither side's. Merge main, then re-run UPDATE_GOLDEN=1 bash test/printffmtparitycheck.sh and review the diff. Same for docs/COMMANDS.md: regenerate it with python3 docs/docs_commands_build.py --bin build/ripwire rather than hand-resolving, or docscommandscheck goes red.

Sorry for the noise.

SINGLE-word cues and left the multi-word ones on substring matching, reasoning that "a phrase carries its
own boundaries". A phrase delimits its own INTERIOR and nothing at its two ends: the first word of `how do`
can finish another word and the last can begin one. `show documentation` contains `how do`; `show issues`
contains `how is`. Both are questions about this repository's history, and both hit the EXPLANATORY guard
and abstained with score="0".

THE REPORTED REPRO DOES NOT REPRODUCE, and the real one is narrower. The review cited `what changed
recently in the documentation directory`, on the reading that `documentation` contains `how do`. It does
not — no cue is a substring of that word, and that prompt already routed recency-window on the unfixed
binary (verified). The false positive needs the cue to SPAN two words: a word ending in `how`/`what`
followed by one beginning `do`/`is`/`are`/`does`. The finding is real; only its example was wrong.

THE FIX. The six explanatory cues are a named table (kExplanatoryCues) matched with boundedFind, the
spelling every other cue in this file already uses. Scoped to that guard: phraseScore keeps substring
semantics for the multi-word router phrases, and the CueMatch comment no longer claims a phrase carries
its own boundaries — it says what is true, that Substring is for cues whose first and last words do not
finish or begin ordinary words, and that a caller who cannot say that of its own cues asks for WordBounded.

RED/GREEN. test/taskroutecheck.sh gains 3 arms. Against the unfixed binary, 2 FAIL:
  FAIL  a cross-word explanatory cue killed the recency route [show issues with the files in storage that
        changed recently]: <task-route status="abstain" confidence="none" score="0" margin="0">
  FAIL  … [show documentation files in storage that changed recently]: same
and the third — `how do i see the files in storage that changed recently` must still abstain — passes
before and after: bounding the cues may not buy the positives at the price of the genuine explanatory
question. ALL PASS after, plain build and asan alike; ASan/UBSan clean on all four prompts (0 stderr bytes).

MEASURED (bench/taskroute_eval.py, 249 rows: the committed 225 plus this lane's 24). Two corpus rows added,
both `test` by the content-hash rule, no hand assignment:

  split | rows | accuracy      | precision | harmful | neg-spec | coverage
  test  | 130  | 0.945 → 0.946 | 1.000     | 0.000   | 1.000    | 0.918
  dev   | 119  | 0.950         | 1.000     | 0.000   | 1.000    | 0.933
  all   | 249  | 0.947 → 0.948 | 1.000     | 0.000   | 1.000    | 0.925

The original 225 still score 0.939 / 0.946 / 0.942 on this binary.

A CLAIM CORRECTED. The previous round recorded "Screen: 1 flagged line (176, pre-existing), DOWN from the
2 this corpus carried before the round". That does not reproduce. Measured with one binary at three
points — 5e1ae38 (the commit before this lane), the previous round's own seal, and this commit — the
contamination screen reports the SAME 2 flagged lines every time: 61 (`i change its`, against the card
literal `did I change its contract?`) and 176 (`the value of`, against the variable-slot cue). Neither is
a row this lane wrote and the count never moved. PROVENANCE.md carries the correction next to the claim.

--quality-delta gating="0", no ack. One sev="minor" row: short-horizon-churn on recencyTaskChoice,
churn="self" — the honest consequence of fixing this function three times in one day.

…s one-place compact posture

origin/main moved to c1915d2 (#218, lane/agent-knowhow) while this round was in
the suite. Four conflicts, all ADDITIVE on both sides, so all four resolved as
unions rather than choices.

src/taskroute.h — the one that mattered. #218 gave classify() a `RouterCaps&
caps = {}` parameter and a recency intent that consumes it; this lane had split
the router into classifyRoutes() (the whole body) plus a classify() that applies
the compact-legend posture ONCE to every choice on the way out. Both survive:
classify() keeps the caps parameter with its default, forwards it verbatim to
classifyRoutes, and applies the posture after. It decides nothing about routing,
so every routing input rides through untouched.

That is the union working rather than two edits colliding: #218's recency intent
spells its commands with NO --legend=compact and gets it anyway, without knowing
the rule exists. It was the 27th command this lane's item 5 predicted — "26
chances to miss one and no rule for the 27th" — and it arrived four hours later
from another lane. The comment now says so.

test/regression.sh — main's alphabetical list carries agentsurfacecheck, this
lane's carries scroundtripcheck; the merged list has both, 615 gates, and the
generator was re-run (docs/gatecount_build.py wrote 615 to 8 marked sites in 3
files; --check green). limits_build --check green untouched.

test/taskroutecheck.sh — main's new "the document defines what it prints" arm
and this lane's R-LEG arm are about different things; both kept.

skills/ripwire-fresh-eyes/SKILL.md — main's new 1a (--rank-by=churn-decay, the
history question) kept whole, and this lane's --legend=compact restored on 1b,
which main's side did not carry.

CHANGELOG.md — both entries.

THE FLOOR MOVED DOWN. #218's new test/agentsurfacecheck.sh arm (A) failed on the
merged tree naming --pin-census and --sarif: its baseline records every --help
flag no agent surface mentions, and the router-skill sentence this round added
(the state-changing and non-XML families the binary refuses --legend=compact on)
NAMES both of them. That file may only be edited downward and fails when a line
stops being a gap, which is exactly what it did. Two lines deleted, 14 -> 12.

Gates on the merged tree: agentsurfacecheck ALL PASS, taskroutecheck ALL PASS,
skilltruthcheck ALL PASS, wrapverbscheck ALL PASS, manifestcheck PASS,
gatecountcheck ALL PASS.

The whole-file candidate is charged its own legend before chooseExpandServe
compares it, so the reason= it prints states what that candidate actually costs.
MEASURED against an archived build of the parent commit, `--expand=distance` on
test/fixture: reason="file 701B &lt; bundle 3702B" -> "file 937B &lt; bundle
3702B", and 701 + 236 = 937 exactly, where 236 B is kExpandWholeFileLegend. The
document is the SAME 1,153 bytes before and after, the same mode="whole-file",
the same est_tokens="303"; that number is the only thing in it that differs.

UPDATE_GOLDEN_EXPECT={expand} matched, 41 labels unchanged. help and help_all
did not move across the merge with #218.

Two conflicts, and one of them is 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. Taking either whole would have silently DROPPED a gate:
  ours adds recentscopecheck and main's #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), and
  the count is a build product: docs/gatecount_build.py regenerated 614 -> 615
  across 8 marked sites in 3 files and --check is clean.

* CHANGELOG.md — three entries, all kept. #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 and
  neither is redundant.

#218 SELF-HEALS ON THIS LANE, and it does: agentsurfacecheck arm (B) is the gate
that asserts a new flag is named where an agent reads, and on the merged tree it
reports `--in=` named beside --rank-by=churn-decay (skills/ripwire-fresh-eyes/
SKILL.md:54), `scope=` named beside `--in=` (:55) and `merge_bombs_skipped=`
beside the ranker (:50) — three rows that could not pass before this lane landed
the flag they name. ALL PASS, not vacuously.

Also merged cleanly: test/legendcoveragecheck.sh, where #218's four added lines
and this lane's rung re-anchor touched different parts of the file.

LIMITS unchanged at 211 caps / 114 classified. build/ and asan/ rebuilt.
Gates re-run on the merged tree, all PASS: agentsurfacecheck, taskroutecheck,
legendcoveragecheck, recentscopecheck, churndecaycheck, manifestcheck,
gatecountcheck, limitstablecheck, nextverbcheck, routehookcheck.

…here both edges moved

#218 added a 385-line file to src/, which changes the corpus the (E) probe's
--for runs over and therefore the budget at which rung zero fires. Re-bisected on
the merged tree, same commit and binary, only the root differing:

    root  38 chars   fires at 1287, NOT at 1288     (was 1288/1290 pre-merge)
    root 137 chars   fires at 1323, NOT at 1324     (was ~1310)

The numbers in the comment are now the merged tree's, bisected rather than swept
in steps of ten. The conclusion is unchanged and the fix is unchanged: 1300 still
sits BETWEEN the two edges, so the old probe would still be green locally and red
on every CI runner. TIGHT=900 has 387 tokens of headroom below the shorter edge
and MARGIN=1100 has 187, both comfortably inside.

That a merge moved the short edge by a single token is the argument for the
MARGIN row rather than against it: the band is a function of the corpus AND the
path, so a comment recording it is stale the moment either moves, and only a row
that re-checks the headroom on every run can be trusted to notice.

Gate: legendcoveragecheck ALL PASS on the merged tree, and ripwirepubliccheck ALL
PASS (the comment states path LENGTHS, never an absolute home path — arm 2 caught
exactly that in the first draft of this text).

Pins moved: none.

…ing it, and a claim the README's own table contradicts

Two outside-diff findings from the PR #215 review, both a document disagreeing with something this same
repository already states.

THE COMPACT-LEGEND POLICY WAS AUDITED IN ONLY ONE DIRECTION. Every `ripwire <dir> --VERB` an agent-facing
skill spells carries --legend=compact where the binary accepts it (--for exempt: its compact legend is its
own). test/skilltruthcheck.sh had two arms for that policy and both START from a command that already
carries the flag — one checks the binary accepts it, the other that --for does not use it. Neither can see
a command that SHOULD carry it and does not, so an omission was invisible to the entire gate. That is how
`ripwire <dir> --rank-by=churn-decay` shipped flagless in ripwire-fresh-eyes's pass 1a (#218). Seven spans
across six skills are fixed: pass 1a and the --help-task route beside it, --max-tokens=3000 (orient's
compress ladder), --no-ignore (orient), --pattern= (navigate), --run-trace= (find-bug), and the two
--grep-in=any recipes in security-scan.

THE GATE GREW THE MISSING DIRECTION. A flagless span must carry the flag when (a) the bare command emits
XML on an empty corpus — stdout's first byte is '<' — AND (b) appending --legend=compact is not refused.
Both halves are asked of the BINARY, never of a list, which is the A1-2 argument unchanged. (a) is what
makes the arm sound instead of noisy: measured on the pre-fix tree, 21 spans look like violations without
it and 6 were real, because a placeholder operand (--arch=rules.txt, --scip=index.scip, --export=cc.json
[:FILE]) fails before the legend check is ever reached and "did not print the refusal" would otherwise read
as "the flag belongs here". FLOOR, stated rather than implied: (a) skips every span whose operand cannot
resolve on an empty corpus, so the arm is a floor on the policy and not a total — those spans are unproven
in both directions, not proven exempt. A positive control (a flagless --flags must classify as a violation)
stops a green from being the classifier failing silently.

RED-FIRST: with skills/ reverted to HEAD the new arm reports "5 of 33 flagless span(s) emit XML and accept
--legend=compact but do not carry it" and names --rank-by=churn-decay, --max-tokens=3000, --no-ignore and
both --grep-in=any recipes; its control passes on that same tree, so the red is the finding and not an
inert probe. Green after the seven spans are fixed: 25 flagless spans swept, none required.

THE README CONTRADICTED ITS OWN DEPENDENCY TABLE. The guide opened with "It has no runtime dependencies"
while the requirements table ~120 lines below says "None for the map itself. The history-backed commands
need `git` on the path, and a repository to read" and then names the twelve commands that do. The prose now
scopes the claim the way the table does and names git. The no-API-key, no-embeddings, no-index-server and
no-daemon claims are untouched: those hold unconditionally. docs/LINEAGE.md's comparison bullet carried the
same unscoped sentence and is scoped identically.

Gates: skilltruthcheck, agentsurfacecheck, wrapverbscheck, readmedriftcheck, readmeexamplecheck,
docscommandscheck ALL PASS; both generators clean. No pin moved.
