fix(#3697): warn when the phase-complete Requirements-line tokenizer under-selects REQ-IDs (#3744)

* fix(#3697): warn when the Requirements line under-selects REQ-IDs

`cmdPhaseComplete` tokenizes ROADMAP's `**Requirements**:` line by splitting
on `[,\s]+` and keeping tokens matching the anchored REQ-ID shape. That is
correct for the canonical comma list the template ships, and silently wrong
for every other form:

  `RANGE-01 … RANGE-05`  ->  the two ENDPOINTS only; the interior IDs are
                             never considered, yet `requirements_updated`
                             reports true with zero warnings
  `RANGE-01…05`          ->  ZERO IDs; the whole line is inert

The silence is structural: the only cross-check, `ghostReqIds`, is itself
`citedReqIds.filter(...)`, so an ID the tokenizer dropped is invisible to it
by construction — and to `traceabilityWriteMisses` and `requirements_updated`
with it.

Warn on both paths. This does not add range support: the selected set is
unchanged, so no existing ledger write changes. The trigger is ID-SHAPED
EVIDENCE only — an ID-shaped substring the tokenizer did not select, or a
range operator joining two IDs — with parenthetical citations and HTML
comments stripped before the scan, so the #2334/#2339 over-warning on
`None`, on the shipped `<!-- brackets optional -->` template comment, and on
annotated lines cannot return.

Regression tests extend the #2316/#2334 fixture family in tests/phase.test.cjs
(10 cases: 4 defect, 2 canonical controls, 4 negative-space controls).

Fixes #3697

* fix(#3697): rework under-selection detection onto tokens, not a free-text scan

Round 2, driven by the P4.6 cross-AI review (codex, gpt-5.6-sol) of b3ce71cb.
That review refuted 5 of 9 claims; three were false-positive classes in exactly
the category #2334/#2339 had to REMOVE:

  `RANGE-01, RANGE-02 - 3 points`        the bare-hyphen alternative read
                                         `RANGE-02 - 3` as a range
  `REQ-01, REQ-02 — locked per ADR-7.`   the trailing period kept `ADR-7.` out
                                         of the anchored filter, so the
                                         unanchored substring scan reported it
                                         as unparsed
  `REQ-01, REQ-02 (see (ADR-7), then ADR-8)`
                                         nested parens left `ADR-8)` behind

Replaces the free-text substring scan + loose range regex with three narrow,
token-based rules (R1 range-shaped token, R2 pure range operator flanked by two
selected IDs, R3 zero-selection with ID-shaped text). Also fixes the review's
CLAIM 9: the warning said IDs were "marked complete" when a ghost range marks
nothing — it now says "selected".

Side effect: the two false NEGATIVES the same review found are now covered —
`RANGE-01 through RANGE-05` and a parenthesised `(plus RANGE-02..RANGE-05)`.

NOT YET DONE (see the handoff prompt): regression tests for the four false
positives, the two new true positives, and the #3697-4 tightening the review's
CLAIM 8 asked for (it currently filters on the warning's phrasing rather than
asserting silence). Verified so far: tsc clean, the 10 existing #3697 tests
green, and a 20-case standalone harness covering every case above.

* test(#3697): pin the v2 token-detector boundary end-to-end

Six new cases + two hardenings for the review findings against v1:

- #3697-1 gains the worded spaced range (`RANGE-01 through RANGE-05`) —
  the operator set's `to|thru|through` arm was previously untested.
- #3697-5 (new): a tight range hidden inside balanced parentheses
  (`RANGE-01 (plus RANGE-02..RANGE-05)`) warns, names the range token,
  and ticks exactly RANGE-01 — the paren shave must not hide it.
- #3697-4 gains the four false-positive classes a free-text detector
  produced: numeric estimate (`- 3 points`), date annotation, em-dash
  citation with trailing period (`— locked per ADR-7.`), and nested
  parenthetical citations.
- #3697-3 and #3697-4 now assert the ENTIRE warnings channel is empty,
  not that one phrase is absent — a re-worded over-warning cannot pass.

Negative control: against the merge-base with its lib rebuilt, all 6
defect tests fail and all 10 controls pass.

* fix(#3697): close round-2 review findings — annotation false positives

Round 2 of the adversarial review (against 822a72a04) refuted five
claims; this closes the false-positive class and the cheap misses:

- R1's bare-hyphen arm now demands a full ID on BOTH sides
  (`REQ-01-REQ-05`): `LETTERS-\d+-\d+` is also a date-like annotation
  (`FY-2026-08`) and a sub-numbered ID, and warning on those is the
  expensive class. Tight hyphen shorthand with a live selection is the
  disclosed false negative; at zero selection R3 still catches it.
- R2 requires the endpoint pair to imply an INTERIOR (same prefix,
  gap > 1): `REQ-02 - REQ-03` selects both endpoints and can drop
  nothing, so an annotation hyphen between adjacent IDs stays silent.
- R3 skips placeholder-led lines: `None (per ADR-7)` is a declared-empty
  line citing its rationale, not unparsed residue.
- Token shave: quotes/backticks now shaved from alphanumeric tokens
  (`` `RANGE-02..RANGE-05` `` warns); punctuation-only tokens get a
  bracket-only shave so `(..)` surfaces its operator.
- 256-char token cap bounds the quadratic unanchored substring test.
- Warning text mentions range expansion only when a range rule fired.

Tests: 6 new cases (22 total). Negative control against the merge-base:
8 defect tests fail, 14 controls pass.

* fix(#3697): close round-3 review findings — half-spaced ranges, cross-prefix annotations, markdown wrappers

Round 3 of the adversarial review (against 2eb92dd0e) refuted four
claims; this closes them:

- Half-spaced ranges (`REQ-01 -REQ-05`, `REQ-01- REQ-05`) split at the
  tokenizer before R1's `\s*` can see them and under-selected silently.
  A glued-fragment rule warns when an operator is glued to a full ID
  with an ID-shaped neighbour on the open side and the endpoint pair
  implies an interior.
- Cross-prefix pairs around a separator no longer read as ranges:
  `REQ-02 - (ADR-7)` and `REQ-02 (...) (ADR-7)` are annotations, and
  real ranges are same-prefix by nature. `impliesInterior` now returns
  false on prefix mismatch and computes the gap with BigInt (parseInt
  lost precision past 2^53).
- The token shave now removes markdown emphasis markers and curly
  quotes, so `**None** (per ADR-7)` reaches the placeholder gate and
  `**RANGE-02..RANGE-05**` reaches R1.
- The unanchored-substring cap rises to 2048 (a markdown-link range
  with a long URL cleared 256); the anchored range regexes scan
  linearly and drop their cap.

Tests: 6 new cases (28 total; 377/377 file-wide). Negative control
against the merge-base: 11 defect tests fail, 17 controls pass.

* fix(#3697): round-4 review finding — word operators excluded from glued-fragment rule

`TOREQ-05` is a valid prefix-agnostic REQ-ID, and the glued-fragment
rule read it as `to` + `REQ-05`, warning on the canonical two-ID list
`REQ-01, TOREQ-05`. Glued fragments are now SYMBOL-operator-only
(`..`+, ellipsis, dashes): a word operator glued to an ID is an ID,
not a range spelling.

Tests: word-operator-prefixed ID control (misparse channel silent; the
fixture's ghost-ID warning legitimately fires, so the whole-channel
assertion stays with the registered controls) and an underscore-wrapped
tight-range defect case. 30 targeted cases; 379/379 file-wide; negative
control: 12 defect tests fail on the merge-base, 18 controls pass.

* fix(#3697): round-5 review findings — trailing word-op glue, dot shave, honest wording

- The glued-fragment TRAILING arm takes the word operators back: an ID
  must end in digits, so `REQ-01through` can never be an ID — the
  round-4 TOREQ collision was leading-arm-only, and symbol-only on both
  arms lost the `REQ-01through REQ-05` typo class.
- A trailing run of 2+ dots survives the punctuation shave: `REQ-01..`
  is a glued range operator, not sentence punctuation, and the shave
  was silently eating the `REQ-01.. REQ-05` form.
- The warning now says the line "could not be parsed as" a
  comma-separated REQ-ID list: `**REQ-01**, **REQ-05**` IS such a list
  — the selector just cannot parse decorated tokens — and a warning
  that misstates the input teaches readers to distrust it.

Tests: two new trailing-glue defect cases (32 targeted; 381/381
file-wide). Negative control: 14 defect tests fail on the merge-base,
18 controls pass.

* test(#3697): use t.after for cleanup per CONTRIBUTING test ruleset

CONTRIBUTING bans try/finally inside test bodies (it masks failures);
the approved shape is `t.after(() => cleanup(tmpDir))`. All seven
converted tests are this PR's own additions; the file's pre-existing
instances are untouched.

* chore(#3697): add changeset fragment for the Requirements-line under-selection warning

changeset-lint fails on this PR (fail_missing_fragment): src/phase.cts is a
user-facing surface and the branch carried no .changeset/*.md. Adds the Fixed
fragment via `npm run changeset -- --type Fixed --pr 3744`, symptom-led per
the house format, with the (#3697) backlink.

* refactor(#3697): extract the Requirements-line detector to a testable surface

Round-3 review Blocker 1 requires a fast-check property test over this
detector (`RULESET.TESTS.property-based-testing`: modules implementing
parsing contracts must include at least one), and Blocker 2 requires
limit-1/limit/limit+1 fixtures on its 2048-char token cap
(`RULESET.TESTS.boundary-coverage.fixtures`). Neither is expressible while
the logic is a closure inside `cmdPhaseComplete`: every existing #3697 test
reaches it by spawning the CLI, and a property test cannot pay a subprocess
per generated case.

So the selector and the three detection rules move to module scope as
`analyzeRequirementsLine` (pure, exported) plus
`formatRequirementsLineWarning`, and `cmdPhaseComplete` calls them. This
commit changes NO behaviour: `tests/phase.test.cjs` is untouched here, and
the pre-round suite passes against it unmodified (403/403).

Two things the move makes explicit rather than incidental. The selector and
the detector tokenize the SAME line DIFFERENTLY — the selector strips only
`[` and `]`, the detector also shaves quotes, emphasis and trailing sentence
punctuation — and that gap is deliberate: it is why `ADR-7)` is not selected
while `ADR-7` is still nameable in a warning. They now sit adjacent with the
reason written down, so they cannot drift apart silently.

And the stale citations in the moved comment are corrected. It pointed at
src/phase.cts:833,920,1078 for the `**Requirements**: TBD` seeds, which had
drifted to 1132/1237/1413, and at `templates/roadmap.md:32`, which is
`gsd-core/templates/roadmap.md:32`. Both are now anchored by content.

* fix(#3697): stop the warning claiming a misparse that did not happen

Round-3 review Major 3 and Minor 4. Both are the same defect: the warning
asserted more than the evidence supported.

MAJOR 3 — a correct comma list such as `RANGE-01, RANGE-02 — RANGE-05
deferred` warned "could not be parsed ... Range forms are not expanded;
rewrite the line". Reproduced: it selects RANGE-01, RANGE-02 AND RANGE-05,
i.e. every ID written on the line. Nothing was dropped, and the pinned
control only stayed silent because its pair was ADJACENT (gap == 1), so the
control was passing by accident of the fixture rather than by the rule.

The obvious fix — go silent — is not available. `RANGE-02 — RANGE-05` as a
range and as an annotation separator are textually identical, and no
token-level rule separates them; staying quiet re-opens the exact silent
under-selection #3697 is about. Deciding the ambiguity by assertion in
either direction is wrong. So it is DISCLOSED: the warning now has two
channels, chosen by whether any ID-shaped token was actually left unselected
(`droppedIdShaped`).

  * something was dropped (tight range, glued fragment, inert residue)
    -> "could not be parsed as a comma-separated REQ-ID list", as before.
  * nothing was dropped (only the spaced-operator rule fired)
    -> "contains what reads as a range between two cited REQ-IDs", stating
    both readings and saying explicitly that an annotation separator means
    the line is already correct.

This retires the "could not be parsed" wording for the four #3697-1 spaced
cases too, and that is a deliberate expectation change rather than a fix
counted twice: those lines never failed to parse either. They still warn,
still name the selected IDs, and still assert the endpoint-only marking is
unchanged; #3697-1 now also asserts the misparse channel stays SILENT.

MINOR 4 — `Deferred (see ADR-7)` reported `Unparsed text: ADR-7`, naming a
citation as requirement content it had failed to read. The trigger is
correct and stays: #3697's acceptance criterion asks for a warning "when it
selects zero IDs from a line that is non-empty and is not the `TBD`
placeholder", and inferring placeholder-ness from arbitrary prose is the
free-text heuristic this detector exists to avoid. What was wrong is the
wording, so the non-range arm now says "ID-shaped text that was not
selected" and names the escape the author actually has (`TBD` / `None`).

Tests: #3697-9 (three spaced forms — must warn, must NOT claim a misparse,
must offer both readings) and #3697-10 (`Deferred (see ADR-7)`, `N/A
(tracked in ADR-12)` — must warn, must not say "Unparsed text", must not
diagnose a range, must name the placeholder escape).

Reversion control: reverting the ambiguous channel fails #3697-9 (3 named
tests); reverting the R3 wording fails #3697-10 (2 named tests).

* fix(#3697): cap every token predicate, complete the dash set, cover the boundary

Round-3 review Blocker 2 and Nit 6, plus one self-found finding. All three
are about the detector's own predicates, so they land together.

BLOCKER 2 — the 2048-char budget had no boundary coverage.
`RULESET.TESTS.boundary-coverage.fixtures` requires limit-1 / limit /
limit+1 for any budget parameter. #3697-B1 and #3697-B2 now exercise 2047 /
2048 / 2049 against BOTH predicate families the cap guards, and each asserts
its fixture's exact length before asserting behaviour, so a mis-built
fixture fails loudly rather than passing at the wrong size. Clause (d) of
that rule — an input pushed within reserve-distance of the limit — has no
referent here: this is a hard cap with no reserve constant beside it, and
the test comment says so rather than leaving the omission to be re-derived.

NIT 6 — the cap guarded only the unanchored ID-substring regex. The
anchored range regexes were left uncapped, justified by a comment asserting
they scan linearly. The finding is right that this is informational (they
are anchored; the input is a local ROADMAP.md), but an asserted property is
cheaper to enforce than to defend, so all three predicates now share one
`short()` guard. #3697-B2 is what pins it: at 2049 the anchored scan must
now decline to classify.

SELF-FOUND (RV4 guard-shape census) — the range-operator set is a list this
code fixes at author time over a domain that grows without it, so the round
owes a census of what the enumeration reaches.

  reached:     `..`+, U+2026, U+2013, U+2014, ASCII `-`, to/thru/through
  NOT reached: U+2010 hyphen, U+2011 non-breaking hyphen, U+2012 figure
               dash, U+2015 horizontal bar, U+2212 minus sign
  consequence: a range spelled with any of those is SILENTLY under-selected
               — #3697's own defect, in the code that exists to fix it

Those five close. They are the same operator at a different codepoint and
carry none of the ASCII hyphen's collision risk, because they are not the
REQ-ID separator: `FY-2026-08` is date-shaped only with ASCII hyphens, so a
U+2010 never reaches the ID shape. They therefore join the NOHYPHEN arm
beside `—` and `–`; the strict full-ID-both-sides shape the bare hyphen is
held to is untouched, and #3697-12 pins that.

Still NOT reached, declined with reason rather than left unstated: `→`, `~`,
`..=`, `..<`, `until`, and `up to` (two tokens, so never one operator
token). Each is a symbol or word with an independent non-range use between
two REQ-IDs — the over-warning class #2334 cost three rounds.

Reversion control: reverting the uniform cap fails #3697-B2 (limit+1);
reverting the dash set fails #3697-11 (5 named tests).

* test(#3697): add the fast-check property coverage the parser rule requires

Round-3 review Blocker 1. `RULESET.TESTS.property-based-testing` (CONTEXT.md)
requires modules implementing parsing contracts to carry at least one
fast-check property test asserting a domain invariant, and the round-2 diff
had zero occurrences of `fc.` across its +311 test lines. Five properties,
1,900 generated cases:

  P1  soundness of silence (boundary containment) — for ANY canonical comma
      list of well-formed REQ-IDs, the selected set EQUALS the written set
      and nothing warns. This is the #2334 over-warning invariant and the
      #3697 under-warning invariant asserted as one statement, over
      generated IDs rather than hand-picked ones. It generalises #3697-4b:
      a prefix beginning with a word operator (`TORANGE-05`) is an ID, and
      P1 covers that class rather than the single example.
  P2  completeness — a same-prefix pair with an interior between them,
      separated by any of the nine spaced operators, ALWAYS warns.
  P3  the #2334 invariant — an ADJACENT pair around a separator can drop
      nothing, so it stays silent however it is annotated.
  P4  totality + idempotency — total over arbitrary strings, deterministic,
      and the formatter agrees with the analysis on whether there is
      anything to say (a warn with no text, or text with no warn, is a
      channel that can go silent or noisy on its own).
  P5  containment — every selected ID is ID-shaped and appears verbatim in
      the input.

Honest scoping, since a property test is easy to overclaim: P1, P3, P4 and
P5 hold against the round-2 code as well as this one — they are regression
guards, not bug-finders, and their value is that the invariants are now
stated and generatively checked rather than implied by examples. P2 is the
one that would have failed before the dash enumeration was completed.

fast-check v4 removed `fc.stringOf`, so the ID-prefix tail is built from
`fc.array(...).map(join)` with the alphabet pinned to the selector's own
`[A-Z0-9]` class.

These live in tests/phase.test.cjs rather than a new
`phase.property.test.cjs`: `lint-test-file-count` caps a production module
at 2 test files and phase.cts is already at its allowlisted entry, so a new
file would trade one gate for another.

* docs(#3697): document the ROADMAP Requirements-line grammar

Round-3 review Minor 5 — the change adds net-new user-visible warning output
for a grammar constraint documented nowhere under docs/. `type: Fixed` is
docs-exempt so this does not block, but a warning about a rule the reader
cannot look up is not actionable, and that is worth fixing whether or not a
gate demands it.

Added as a subsection of `phase complete` in docs/CLI-TOOLS.md, beside the
existing SUMMARY artifact-check advisory it is a sibling of: the supported
comma-list form, why ranges are deliberately not expanded, that `TBD` and
`None` are the entire placeholder vocabulary, and what each of the two
warning voices means — including that the range/annotation one may be
reporting a line that is already correct.

Existing file rather than a new one, deliberately: docs/ carries generated
indexes and zh-CN / ja-JP trees, and a new top-level page invites a parity
or index gate this change has no reason to touch.

* fix(#3697): rule-scope the warning-channel discriminator

Self-found at the round's pre-push review, against the Major 3 fix two
commits back. That fix chose the channel from a LINE-GLOBAL question — "was
any ID-shaped token left unselected?" — while the rules that produce the
warning are not line-global. The two disagree as soon as the line carries an
ID-shaped token no rule fired on:

  `RANGE-01, RANGE-02 — RANGE-05 deferred per (ADR-7)`

`(ADR-7)` survives the selector's bracket strip, so the global test called it
a drop and sent the line to the assertive channel — putting the false "could
not be parsed ... rewrite the line" claim back on a correct line. That is
review finding Major 3 returning through a side door, and it directly
contradicts #3697-4, which pins a parenthetical citation as NOT unparsed
residue.

The discriminator is now rule-scoped: R2 is the only ambiguous rule, so the
ambiguous channel requires that R2 fired, that no other rule did, and that
every endpoint R2 fired on was actually selected. The last conjunct is not
redundant — the detector shaves brackets and the selector does not, so R2 can
fire on a `(RANGE-02)` that was never selected, and that IS a drop:

  `RANGE-01 (RANGE-02) — RANGE-05`   -> assertive, correctly

`droppedIdShaped` is replaced by `spacedRangePairs` (R2's hits, so the
channel can ask about the endpoints the rule fired on) and the
`rangeReadingOnly` verdict.

Reversion control: against the line-global rule, #3697-9b fails. #3697-9c
passes under both rules — there the dropped token IS the R2 endpoint, so the
two agree; it is a regression guard, not a bug-finder, and is recorded as
such rather than counted as a second control.

* fix(#3697): hold every dash to the strict range shape, not just ASCII

Self-found at the round's pre-push review, and it CORRECTS a claim made two
commits back. That commit widened the range-operator set by five Unicode
dashes and asserted they "carry none of the ASCII hyphen's collision risk,
because they are not the REQ-ID separator". That reasoning was wrong. The
collision is a property of the SHAPE — `PREFIX-\d+ <dash> \d+` is also a date
(`FY-2026-08`) and a sub-numbered ID (`API-2-01`) — and the shape does not
care which dash sits in the operator slot, because the ID's own separator is
still ASCII either side of it. Measured:

  RANGE-01 (target FY-2026-08)   silent   <- pinned by #3697-4
  RANGE-01 (target FY-2026‐08)   WARNED   <- same line, U+2010

So the widening reintroduced the #2334 over-warning class on a date
annotation. It also exposed that the inconsistency PREDATES this PR: U+2013
and U+2014 were already in the loose arm at ce71dd399, so the en- and em-dash
forms of that same date annotation warned before round 3 ever ran.

One rule for every dash: a tight range spelled with any of the eight must
carry a FULL ID on both sides, exactly as the bare hyphen already had to.
`..`, `…` and the word operators stay loose — no date or sub-number reading
exists between two numbers, so the strict shape would cost them coverage for
nothing.

The cost is a false negative, and it is one the design already accepts:
`RANGE-01, RANGE-02-05` is silent today, deliberately, and now
`RANGE-01, RANGE-02–05` is too. That removes an inconsistency rather than
opening a gap, and a bare `RANGE-02–05` still warns — it selects nothing, so
R3 catches it.

Tests: #3697-13 (date annotation AND sub-numbered ID silent for all eight
dashes), #3697-13b (full-ID tight range still warns for all eight),
#3697-13c (loose operators keep their numeric endpoint), #3697-13d (the
accepted false negative is symmetric, and the bare zero-selection line still
warns).

* fix(#3697): close the round's own pre-push review findings

An adversarial cross-AI review of this round refuted 4 of its 10 claims. All
four were real. Every fix below is to code THIS round introduced.

1. THE SOFT VOICE CLAIMED TOO MUCH (refuted CLAIM 1).
   `REQ-01, (REQ-02), REQ-03 — REQ-05` took the range-reading voice and told
   the author "the line is already correct and nothing needs to change" — while
   `(REQ-02)` had been dropped by the selector, which does not strip
   parentheses.

   The channel choice is still right, and deliberately so: `(ADR-7)` and
   `(REQ-02)` are the SAME shape, so routing on "was anything unselected?" puts
   the false "could not be parsed" claim back on a line carrying a citation —
   the misroute fixed two commits ago. No rule can adjudicate this; the author
   can. So the voice stops asserting the line is correct (it now speaks about
   the SEPARATOR, which is all it has evidence about), and BOTH voices gained a
   factual clause naming ID-shaped text the selector skipped, with the reason
   (brackets are not stripped) and no verdict attached.

2. THE CAP SILENCED A LINE THAT USED TO WARN (refuted CLAIM 2).
   A 2049-char range token warned before this round and went silent after it:
   the "uniform cap" commit bounded the predicate and, with it, the warning.
   That is #3697's own defect, introduced by the fix for a nit.

   The cap bounds the WORK, not the warning. An over-cap token carrying `-` is
   now recorded as unclassified (a linear `includes`, never the unanchored
   regex the cap exists to keep off it) and gets its own voice: "could not be
   checked ... the REQ-ID selection on this line is unverified". Unclassified
   is reported, never treated as clean.

3. THE CAP WAS NOT UNIFORM (review MISSED finding).
   R2 capped the operator token but not its neighbours, so
   `<2049-char ID> .. <2049-char ID>` still ran REQ_ID_SHAPE_RE and BigInt over
   both endpoints unbounded. The glued rule had the same hole. Every
   participant is capped now.

4. PROPERTY P5 WAS VACUOUS (refuted CLAIM 5).
   It drew from a bare `fc.string()`, which over 500 samples produced max
   length 10 and ZERO inputs containing a REQ-ID — the loop body never executed
   an assertion. A containment property that never contains anything is a green
   test measuring nothing. The generator now interleaves real IDs with noise
   and the property ASSERTS it saw them (>50/500), so it can never silently go
   vacuous again. The free-form coverage it was actually providing survives,
   honestly labelled, as #3697-P6.

   The same finding refuted this round's claim that P2 distinguishes pre-round
   behaviour: every operator P2 uses was already in the pre-round operator set.
   P2 is a regression guard, and its comment now says so.

Also: docs/CLI-TOOLS.md repeated the broken channel claim verbatim (review
MISSED finding) and is corrected with the code.

Tests: #3697-9d (soft voice names the skipped ID, never claims the line is
correct), #3697-9e (over-cap token reported as unclassified, still warns),
#3697-9f (R2 and the glued rule cap their neighbours). #3697-B1/B2 now key the
boundary on the PREDICATE's verdict with `warn` asserted true at every length —
asserting `warn === false` at limit+1 was itself finding 2.

* docs(#3697): describe the third voice and the dash rule

Follow-on to the review-findings commit: that commit corrected the docs' claim
about the soft voice but left two things the code now does undescribed.

- There are THREE voices, not two. The over-cap voice ("could not be checked
  ... unverified") arrived with the fix for the review's CLAIM 2 and had no
  entry.
- Dash spellings require a full ID on both sides, and `..` / `…` / the word
  operators do not. That asymmetry is deliberate and load-bearing —
  `PREFIX-<digits><dash><digits>` is date- and sub-number-shaped — so a reader
  hitting `REQ-01-05` and getting silence has no way to find out why. The
  accepted cost (`REQ-01, REQ-02-05` unreported, bare `REQ-02-05` still
  reported) is stated rather than left to be discovered.

Documentation only; no behaviour change.

* fix(#3697): close the continuation review's findings

A continuation of the same adversarial reviewer, run against the reworked
round, refuted 6 of 7 claims. Four were real defects in this round's own work
and are fixed here; the other two are answered rather than changed, below.

1. THE SKIPPED-TEXT CLAUSE WAS ON ONE VOICE, NOT BOTH (refuted CLAIM A).
   The previous commit's message said both voices gained it. Only the soft
   return appended it. The assertive voice now carries it too — and, because
   that voice already names range tokens and inert residue under its own
   clauses, the note is filtered to what those did not already name. A warning
   that says the same token twice is one readers learn to skim.

2. THE CLAUSE'S WORDING WAS FALSE (also CLAIM A).
   It read "brackets and parentheses are not stripped". Square brackets ARE
   stripped by the selector — `[REQ-01, REQ-02]` is the documented form — so
   only parentheses qualify. Corrected in the message and in docs/CLI-TOOLS.md,
   which had inherited the same error.

3. THE OVER-CAP RULE STILL SILENCED A LINE (refuted CLAIM B).
   `oversizedTokens` filtered on `includes('-')`, which misses an over-cap
   OPERATOR: `REQ-01 <2049 dots> REQ-05` warned before this round, R2 declined
   to classify it once capped, and nothing reported it. That is the exact
   regression the field was added to close, one input over. Any token past the
   cap now counts — what it contains is irrelevant when we could not read it.

4. AND THEN OVER-REPORTED ONE (review MISSED finding).
   With (3) in place, a 2049-character CANONICAL REQ-ID was selected by the
   uncapped, fully-anchored selector AND flagged "REQ-ID selection on this line
   is unverified" — a contradiction inside one warning. A token the selector
   took was examined end to end, so it is excluded.

Two findings are answered, not changed:

  CLAIM C — the selector's own `REQ_ID_SHAPE_RE.test` is uncapped. True, and
  deliberate: this round does not touch what gets MARKED, and the pattern is
  anchored at both ends with no nested quantifier, so it is linear. The claim
  that "all predicate paths are capped" was too broad; the DETECTOR's are.

  CLAIM E — `REQ-01, REQ-02<dash>05` is silent for every dash. That is the
  documented, deliberate cost of holding dashes to the strict shape, and it is
  symmetric with ASCII, which behaved that way before this PR. The reviewer is
  right that "without losing a range spelling that should be detected" was too
  strong; a bare `REQ-02<dash>05` still warns.

Tests: #3697-9g (clause on the assertive voice, no repetition, bracket claim
true), #3697-9h (over-cap operator does not silence the line), #3697-9i (a
selected over-cap ID is never called unverified). #3697-9f is rebuilt — its
first version used the SAME id twice, so R2 could not have fired even uncapped
and it proved nothing; it now uses endpoints with a gap and fails when the
neighbour cap is removed.

Reversion control: all four fixes fail a named test when reverted in isolation
(#3697-9h, #3697-9i, #3697-9g, #3697-9f).

* fix(#3697): scope the over-cap exemption to what could actually pair

A second continuation of the same reviewer, against the reworked round,
confirmed the two claims that matter most and refuted three. This closes the
one real defect; the other two are answered below.

CLAIM J / CLAIM K (one defect, found from both directions). The previous
commit exempted EVERY selector-accepted token from `oversizedTokens`, on the
reasoning that the selector is uncapped and anchored so it examined the whole
token. True of that token's SELECTION — and not the same as "no rule was
suppressed by it". Two over-cap valid IDs either side of `..` are both
selected, so both were exempted, and R2 is capped: a line that warned before
this round went silent.

That is the third appearance of one class in this round — the cap suppresses a
check, and the suppression is not reported. Each fix for it over-corrected in
the opposite direction, which is why the rule is now stated in terms of what
was actually suppressed rather than in terms of the token: an over-cap token is
exempt only when it was selected AND nothing beside it could have paired with
it into a range (no range operator, no glued fragment, no second over-cap
token). Everything else is unexaminable and says so.

Two findings are answered, not changed:

  CLAIM M — the reviewer demonstrated, with driven evidence, a contextual rule
  that catches `REQ-01, REQ-02-05` while leaving `FY-2026-08` and `API-2-01`
  silent: recognise `PREFIX-a<dash>b` only when another SELECTED id on the line
  shares that prefix. That refutes this round's claim that the strict-dash
  trade was FORCED, and the claim is withdrawn — it is a design choice. The
  choice stands for this PR: the conservative rule is what ASCII already did
  before #3697, adopting a new contextual heuristic unreviewed at the end of a
  round is how the last three defects in this round were made, and #3697 asks
  for a warning rather than better range inference. Named here so the
  alternative is on the record rather than lost.

  Docs MISSED — CLI-TOOLS said every token over 2,048 characters "is not
  classified at all" and warns. Selection is not bounded; only range detection
  is. Corrected.

Confirmed by the same pass, and worth recording because they are the PR's
load-bearing promises: a 20,000-input comparison of the pre-extraction selector
against HEAD found `mismatches=0` (nothing about which REQ-IDs are MARKED has
changed), and the uncapped selector regex was measured linear from 100k to 800k
characters.

Tests: #3697-9f now asserts the range case is reported rather than silent, and
#3697-9j pins the exemption's scope in both directions. Reversion control:
restoring the blanket exemption fails both.

* fix(#3697): warn on zero selection, as the acceptance criterion asks

`Deferred`, `N/A`, `Pending`, `TBA` and `-` selected no REQ-IDs and stayed
SILENT, while three shipped artifacts said they warned: `docs/CLI-TOOLS.md`,
the `placeholderLed` census comment, and the advice string the command emits
to the user. The asymmetry was the tell — `Deferred (see ADR-7)` warned,
because the citation supplied the ID-shaped residue R3 required, while bare
`Deferred` did not. The claim was written into three places and never
executed once.

This is also #3697's AC-1b/AC-4 verbatim: "warn when `citedReqIds.length ===
0` while the raw capture is non-empty and not `TBD`".

R3b keys on the SELECTION being empty, never on what the prose means, so it
adds no free-text heuristic. It is deliberately not gated on ID-shaped
residue the way R3 is, and the negative space is what settles that: all
fifteen #2334/#2339 fixtures are held silent by non-zero selection or by
`placeholderLed`, and not one of them by the ID-shape gate — measured, not
argued. The gate was buying no negative space while costing the acceptance
criterion.

`tokens.length > 0` keeps an empty line and a comment-only line silent: the
tokenizer strips `<!-- ... -->` before splitting, so the shipped template's
own comment cannot reach the rule.

Selection behavior is unchanged. This warns; it never invents an ID.

Also extracts `warn` to a named const (round 3 review Minor 3) — this commit
adds a disjunct to exactly that predicate, and in the return literal a later
reordering would be a TDZ ReferenceError rather than a reader-visible error.

Tests: #3697-14 (six zero-selection lines warn and tick nothing, and the
warning names the TBD/None escape), #3697-14b (five placeholder spellings
stay whole-channel silent), #3697-14c (comment-only line stays silent).
Fail-first controls: all six #3697-14 cases fail against the pre-fix tree;
-14b and -14c pass at both ends, which is correct — they pin silence the
widening must preserve.

* fix(#3697): name the REQ-ID a glued delimiter dropped

`RANGE-01; RANGE-02` selects only RANGE-02 and marks only RANGE-02, with
`requirements_updated: true` — #3697's own half-success failure mode, reached
by one wrong delimiter, and silent before this rule. It is the issue's AC-1a
("a warning whenever the line contains ID-shaped content that the tokenizer
did NOT select") at the shape most likely to be typed by accident.

Round 4 review rated this Major rather than Blocker on the ground that the
case is indistinguishable from a parenthesised citation, since `(ADR-7)` also
shaves down to a bare ID. At the RAW token level it is distinguishable, and
that is what makes the rule shippable: `REQ-01;` is shaved of a trailing
DELIMITER, `ADR-7)` of a citation wrapper. R4 keys on that shave class and
requires the token to sit outside any parenthetical.

Measured before implementing: 0 false positives and 0 false negatives across
21 probes, including all fifteen #2334/#2339 negative-space fixtures. A first
cut without the parenthetical test scored 3 false positives — every one of
them a colon inside a citation (`(see ADR-7: section 3)`) — which is why that
test is the rule's boundary rather than an optimisation.

Adds the delimiter census the module did not have. The range-operator domain
was already censused; the comma-substitute domain was not. Swept 26
spellings: exactly two produce a silent under-selection, `; ` and `: `. Every
other spelling either selects both IDs or selects none and already warns. The
review hand-listed the semicolon; the colon is the sibling that sweep found,
and it fails identically.

`rangeReadingOnly` now excludes an R4 hit — the ambiguous voice claims nothing
was dropped, and must not speak for a line where something demonstrably was.

Tests: #3697-15 (four delimiter shapes warn, name EVERY dropped ID, and tick
exactly the unchanged selection), #3697-15b (three citation forms stay
whole-channel silent). Fail-first control: all four #3697-15 cases fail
against the previous commit's tree; -15b passes at both ends, pinning the
boundary the widening must not cross.

* fix(#3697): give the Requirements-line warning a stable machine kind

The warning's kind existed only in the prose of its message, so every consumer
and every test had to regex an English sentence — and rewording a message
silently un-asserted the tests that pinned it. Round 4 review Major 3.

The repo already had the settled seam for exactly these semantics.
`CONTEXT.md` records `diffLiveConfig` emitting `kind:'unverified'` for a
truncated scan, which is precisely this module's third voice; and
`WAVE_CLEANUP_WARNING` in `src/worktree-safety.cts` carries codes for the same
reason. ADR-3473 Decision 3 ("failure is a value") points the same way.

`formatRequirementsLineWarning` now returns `{ code, message }` instead of a
bare string, which also settles round 4 Nit 3 — `null` still means CLEAN, a
legitimate value, but the success arm is no longer a naked string one field
away from the shape the ADR standardises on.

The kind is carried ALONGSIDE the prose, never instead of it. `warnings[]` is
a documented `string[]` in `phase complete`'s JSON output, rendered by
execute-phase.md's "If has_warnings is true" step, so re-typing its elements
would be a breaking output-contract change for a shipped command. The code is
emitted as its own additive `requirements_line_warning` field, absent
entirely when the line is clean.

Vocabulary, exported so tests key on it rather than on string literals:
`req-line-misparse`, `req-line-range-reading`, `req-line-unverified`.

Tests: channel ROUTING in #3697-9/-9b/-9c/-9d/-9e/-9g/-10 now asserts the code;
message-content assertions stay where the user-visible wording is itself under
test. #3697-16 pins the code end-to-end through the CLI's JSON for four line
shapes and asserts warnings[] is still a string[]; #3697-16b pins that a clean
line emits no kind at all, because a field present on every run carries no
information. #3697-P4 holds kind-and-message-appear-together and
kind-is-in-the-declared-vocabulary over arbitrary input, so a channel added
later cannot ship without one.

* test(#3697): pin the divergence against the second parser of the same line

CLAUDE.md, KNOWN DEFECTS & ANTI-PATTERNS: "Generative Fix Divergence: when
sharing constants/arrays/parsers between parallel surfaces, add a parity
assertion test that fails if they diverge." Round 4 review Major 2.

`normalizePhaseReqIds` (src/gap-checker.cts) parses the SAME ROADMAP
`**Requirements:**` value — its own docblock says callers "may pass the
roadmap value through verbatim" — and diverges on four axes. Measured, not
inferred:

  line                                    phase complete      gap-checker
  RANGE-01..RANGE-05                      []                  5 IDs
  None (per ADR-7)                        []                  ["ADR-7"]
  (REQ-02)                                []                  ["REQ-02"]
  REQ-01a                                 []                  ["REQ-01a"]
  REQ-01, REQ-02                          both                both

This pins the divergence rather than removing it, which is the review's
second option and the correct one here: unifying the two would change what
`phase complete` MARKS, and "the ledger-writing set is byte-identical to base"
is the one invariant this PR holds fixed. Every axis is now asserted in BOTH
directions, so drift on either side fails here instead of widening silently.

The range axis is a DELIBERATE disagreement and is labelled as such — #3697
declines range expansion in terms ("I am not asking for range syntax to be
supported") while gap analysis adopted it under #1269.

The placeholder axis is the one worth reading twice: `None (per ADR-7)` is a
declared-empty line to `phase complete`, which reads the lead token, and a
one-requirement line to gap-checker, which strips parentheses first so the
citation survives its ID-shape filter. That is a citation being reported as a
requirement.

#3697-17b states the cost concretely: one line, five requirements in scope to
gap analysis and zero to phase complete. This PR is what makes that
contradiction visible, by finally giving the silent side a voice.

* fix(#3697): stop the skipped-text rider reporting a date, and close the 4b channel gap

Two round 4 review minors, both about a warning saying something it cannot
support.

MINOR 2 — false rider content. `REQ_ID_SUBSTRING_RE` is unanchored, so
`FY-2026-08` matches as `FY-2026` and lands in `unselectedIdShaped`.
`REQ_RANGE_TOKEN_RE`'s entire strict-dash arm exists to keep that shape
silent, and #3697-4 pins `RANGE-01 (target FY-2026-08)` as producing no
warning at all — but whenever some OTHER rule fired on a line that also
carried a date annotation, the rider told the author to "check whether any of
it is a requirement" about a date. Not a false warning, since the line was
warning anyway; false CONTENT, in the #2334 voice, through the side door.

Filtered at the MESSAGE rather than in the analysis: `unselectedIdShaped`
stays a faithful record of what the selector skipped — it is documented as a
fact that never routes — while the user-facing clause declines to assert
requirement-ness about a shape the design already ruled unadjudicable.
#3697-18b is the other half, so the filter cannot become a silencer: a
genuinely dropped REQ-ID is still named.

MINOR 1 — `#3697-4b` asserted only that the ASSERTIVE channel stayed silent,
so a regression routing `RANGE-01, TORANGE-05` into the AMBIGUOUS channel
would have passed. Whole-channel silence is not available on that fixture (the
pre-existing ghost-ID warning legitimately fires on the unregistered
`TORANGE-05`), so the precise assertion is that no Requirements-line warning
of ANY kind was emitted. The machine code added earlier in this round is what
makes that statable; before it, "both channels" could only have meant a second
prose regex.

* docs(#3697): record the Requirements-line seam in CONTEXT.md

CLAUDE.md names the CONTEXT.md glossary as a PR gate, and
`get_cochange_context(src/phase.cts, 45d)` ranks CONTEXT.md 4th at 25
co-changes — above src/init.cts and src/roadmap.cts. This PR introduced a
named seam, three warning kinds, a bound, a rule taxonomy and a deliberate
cross-parser divergence, and recorded none of it. Round 4 review Major 4.

The precedent is explicit rather than inferred: the directly analogous seam
is already there as `LIVE-CONFIG.GUARD.SEAM.truncation`, including its bound
and its boundary obligation — and that entry is the one this module's third
voice was modelled on.

Eight predicates, in the machine-oriented section beside it:

  .module                    the two exported functions and the code vocabulary
  .selector-identity         citedReqIds is byte-identical to base and is the
                             only thing reaching the ledger — a change to what
                             phase.complete MARKS is outside this contract
  .rules                     R1 / R2 / R2' / R3 / R3b / R4 / over-cap
  .kinds                     the three codes, and why they ride beside
                             warnings[] rather than inside it
  .cap                       2048, neighbours included, and the boundary rule
  .placeholder               the gate that actually holds the negative space
  .census-domains            both open domains with their NOT-reached members
  .gap-checker-divergence    the four axes, pinned not unified

The changeset type is `Fixed`, which exempts this PR from the docs/
co-change requirement — but the glossary gate is separate from that
exemption, and the 2048 cap in particular is a machine-canon-shaped fact
that until now existed only inside a source comment.

`docs/CONTEXT-INDEX.json` regenerated (269 predicates); lint:generated-sync
confirms all six targets in sync.

* docs(#3697): document what the command now does, in one changeset sentence

DOCS. The grammar section predated this round's two new rules, so it
under-described the behaviour it exists to make lookup-able:

- The placeholder paragraph enumerated three words; the rule is a DEFAULT.
  Any wording that selects no REQ-IDs warns, and the placeholders are matched
  as the LEAD token, so `None (per ADR-7)` and `**None**` are declared-empty
  too. The comment-only line is called out, because "any other wording" would
  otherwise read as covering the shipped template's own `<!-- ... -->`.
- The comma rule was implicit. `REQ-01; REQ-02` marks only REQ-02, and it is
  the quietest way to lose a requirement on this line — `requirements_updated`
  reads `true` either way — so it gets its own paragraph, with the
  parenthetical exemption stated beside it.
- The machine kind is documented where a consumer would look for it, with the
  instruction to key on the kind rather than the wording.
- The skipped-text note no longer implies it reports date shapes; it
  deliberately does not, and silently omitting that left the doc promising the
  behaviour this round removed.

CHANGESET (round 4 review Minor 4). CONTRIBUTING.md's format is
`**<Bold user-visible change>** — <symptom-led explanation>.` and both
canonical examples are one sentence; this fragment ran three. Now one, and
covering what the round actually delivers rather than only the range shape it
started from.

* test(#3697): keep phase.test.cjs off the docs-guard exemption fingerprint

A comment added earlier in this round named `docs/CLI-TOOLS.md` by path. The
docs-guard exemption ratchet (#3753 FIX 3) fingerprints literal `docs/`
references in exempt test files and fails when a new one appears, so that
comment turned four green gates red — `ci-docs-guard-registry` and the
registration lint — for a file that reads no documentation at all.

Caught by diffing the full suite's failing-name set against the same suite run
at `upstream/next` in a probe worktree: 33 of 37 failures reproduce at base
(install / config-home / shadowing tests under the sandbox HOME), and exactly
these 4 did not.

Rephrased rather than baselined. Adding the path to
DOCS_GUARD_EXEMPT_DOCS_PATHS is the sanctioned response when a test genuinely
starts READING a new docs path — the violation text asks the author to
re-confirm the exemption still holds. Nothing here reads documentation; the
guard matched prose. Baselining would have recorded a coupling that does not
exist and made the next reader wonder what phase.test.cjs does with
CLI-TOOLS.md. The comment still names where the contract is written, just
without planting a path string.

* fix(#3697): close four defects this round's own pre-push review drove

An adversarial cross-AI review of this round, run before the push, returned 6
CONFIRMED and 4 REFUTED. Every refutation was driven against the built tree,
and every one was a shape the author had not probed — the rules were correct
across the probe set and wrong just outside it.

(1) R4 FALSE POSITIVE, and it is the #2334 over-warning class arriving through
the rule added to close a different hole. `REQ-01, see ADR-7: section 3` fired:
`ADR-7:` is the same shave class as `REQ-01;`, and the parenthetical test does
not reach a BARE citation. The FP probe that scored this rule 0/0 only ever
tested the parenthesised form.

Fixed by requiring the dropped id's prefix to agree with a SELECTED id — the
module's own idiom, not a new heuristic: `reqEndpointsImplyInterior` already
demands an agreeing prefix for the same reason. Cost, stated in the census: a
dropped id whose prefix is on no selected id (`REQ-01, FOO-02: x`) stays
silent. Same trade the strict-dash rule takes — under-report a rare shape
rather than over-report a common one. Pinned as a declared blind spot by

(2) R4 FALSE NEGATIVE, on the DOCUMENTED form. `[REQ-01; REQ-02]` dropped
REQ-01 silently: the selector strips square brackets and R4's raw scanner did
not. The bracket spelling the shipped template recommends was the one shape the
rule could not see.

(3) The rider filter suppressed a REGISTERED requirement. `API-2-01` is a legal
requirement id — gap-checker's `parseRequirements` accepts it from
REQUIREMENTS.md — so a `\d+-\d+` filter hid a genuinely dropped requirement
behind a rule meant only to hide dates. Narrowed to a four-digit year segment.
The earlier #3697-18 case asserting `API-2-01` should be suppressed is REMOVED,
and the removal is recorded in place: its premise was refuted, it was not
inconvenient.

(4) An INVISIBLE line warned. A lone U+200B carried a token to the parser while
reading as empty to the author, so R3b fired with nothing on screen to explain
it. Zero-width and format characters are now stripped — stripped rather than
treated as delimiters, because splitting on one would fabricate two fragments
out of one ID.

Also corrects the documentation the same review found overstated: the line is
split on commas AND whitespace, and the ID shape is matched case-insensitively,
so `REQ-01 REQ-02` and `req-01, req-02` both select and neither warns. That was
pre-existing selector behaviour; this round is the one that asserted the docs
were true of it.

Tests: #3697-19 (four invisible-only shapes), -19b (embedded zero-width is
stripped, not split on), -19c (three citation forms), -19d (both bracket
spellings), -19e (both halves of the rider boundary), -19f (the declared blind
spot), -19g (the two documented tolerances). 500 tests in phase.test.cjs, 0
failures; lint:ci clean.

* fix(#3697): generalise the drop rule, and stop the invisible fix hiding a drop

The pre-push review's continuation refuted six of seven follow-up claims. The
first one is the one that mattered: the invisible-character fix committed in
c7dce173a INTRODUCED #3697's own defect. Stripping zero-width characters from
the detector wholesale made `REQ-01<ZWSP>, REQ-02` go SILENT — the selector
really does drop REQ-01, and the strip removed the only evidence of it. The
test written alongside asserted the tokens and the empty R4 result and never
asserted `warn`, so it DOCUMENTED the bug rather than catching it; that
omission was the reviewer's own MISSED finding.

An invisible is two different questions about one character, and the fix is to
stop conflating them: absence-of-content for the empty test, DECORATION on a
token for the drop rule. Neither is a reason to delete it from the line.

R4 is generalised accordingly, because the continuation drove four more shapes
a trailing-delimiter-only regex could not see — `REQ-01 ;REQ-02`,
`REQ-01 :REQ-02`, `**REQ-01;** REQ-02`, the backticked form — plus
`**REQ-01**, REQ-02`, where emphasis alone defeats the selector. These are one
class: decoration on a token the selector then cannot take. One rule, not four
patches; patching them individually is how a list stays short and wrong.

PARENTHESES ARE NOT DECORATION, and the suite caught me learning that: shaving
them made `REQ-01, (REQ-02), REQ-03 — REQ-05` report a glued delimiter that was
never there and broke #3697-9d's channel routing with it. A parenthesis is this
rule's citation marker.

The rider stops adjudicating an undecidable shape. `API-2-01` is a legal
requirement id and `API-2026-08` is too, while `FY-26-08` and `FY-2026-08-15`
are dates — no regex separates them, and both filters this round tried scored a
miss in each direction. It now NAMES the token and states the ambiguity, which
is the same thing the two warning voices already do about a range separator.
Filtering hides a real dropped requirement; reporting it bare asks the author
whether a date is a requirement; saying "this may equally be a date" does
neither.

The census and the docs are corrected to what the code does, including the part
that is NOT complete: the prefix gate does not stop a citation that SHARES a
selected prefix (`ADR-01, see ADR-7: sec 3` fires), and nothing at token level
separates that from a real drop. A prose heuristic on "see" is the free-text
detector this module exists to avoid, so the honest move is to say so.

CLAIM 17 — the invariant that actually matters — came back CONFIRMED on a
20,000-run fast-check property over arbitrary Unicode: `citedReqIds` is
identical to upstream/next's for every input, and marking is untouched.

513 tests in phase.test.cjs, 0 failures; lint:ci clean.

* fix(#3697): gate the drop rule on evidence, and stop an unmatched paren swallowing the line

Third pass of the round's own pre-push review, scoped to regression-hunting
rather than further polish. Three findings, all driven, all mine.

R4 OVER-WARNED on markdown styling. `REQ-01, see **REQ-7** for context` claimed
a dropped requirement: the previous cut treated any shaved decoration as
evidence, and emphasis is not evidence. Nothing separates that line from
`**REQ-01**, REQ-02` meaning to list one, so the rule now requires a positive
signal — a glued `;`/`:` (a list separator was INTENDED) or an invisible (the
token is CORRUPTED; nobody types one on purpose). Emphasis alone falls back to
the skipped-text rider, which names the id without asserting a drop, exactly as
`(REQ-02)` is handled. That is the #2334 class caught one cut before shipping.

R4 UNDER-WARNED on `**REQ-01**; REQ-02` — one shave pass cannot reach a wrapper
sitting behind a delimiter. Shaves to a stable point now.

The range OPERATOR lost its invisibles handling. `REQ-01 <ZWSP>..<ZWSP> REQ-05`
went silent, because the previous commit removed the invisible strip from BOTH
the tokenizer and R4 when only R4's was wrong. An invisible is two questions
about one character: for the classification rules it is noise and is stripped
from the token; for the drop rule it is the evidence and must survive on the
raw line. Stripping in both places hid a dropped id; stripping in neither hid a
range. The reviewer's MISSED finding named the missing control — regression
tests covered invisibles inside ids and not beside operators — and #3697-19i is
that control.

UNBALANCED PARENTHESES swallowed the line. `REQ-01, (note REQ-02; REQ-03`
reported nothing: a running-depth counter left the unclosed `(` open through
end-of-line, so every genuine drop after it inherited citation immunity. A
parenthesis confers that immunity only as part of a MATCHED span now — an
unmatched one is a typo, not a citation.

CLAIM 22 re-confirmed on a fresh 20,000-run property over arbitrary Unicode:
`citedReqIds` identical to upstream/next, marking untouched, warnings appended.

522 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite carries zero
head-only failures against a probe worktree at upstream/next.

* fix(#3697): make delimiter ADJACENCY the rule, and delete matched citations outright

Fourth and final pass of the round's own pre-push review. Three findings, and
they shared one root cause, so this is a narrower rule rather than a longer list
of shapes.

TOKEN-WIDE PAREN IMMUNITY LEAKED. `REQ-01, REQ-02;(note) REQ-03` is a single
whitespace token, so a matched parenthetical inside it conferred immunity on the
`REQ-02;` sitting OUTSIDE the parens, and the drop went silent. Matched spans
are now deleted from the line outright — which states what is actually meant,
that for this rule a citation is not on the line — and an UNMATCHED paren is a
typo that confers nothing. That also retires the running-depth counter whose
previous bug was the mirror image: an unclosed `(` swallowing the rest of the
line.

DECORATION WAS TESTED TOKEN-WIDE, so `REQ-01, see **REQ-7**; next topic` was
reported as a dropped requirement. It is a citation with sentence punctuation.
The rule is now ADJACENCY: styling is stripped, then the `;`/`:` must be
touching the id. `REQ-01;`, `;REQ-02` and `**REQ-01;**` qualify;
`**REQ-01**;` does not, because outside the styling that character is
punctuation. An invisible needs no adjacency test — nobody types one on
purpose, so anywhere in the token it is corruption rather than intent.

`**REQ-01**; REQ-02` therefore goes silent, and the test row asserting
otherwise is inverted rather than deleted quietly: it was added one commit ago
on the reasoning this pass refuted, and nothing distinguishes it from
`see **REQ-7**; next topic`.

Worth recording plainly: three successive cuts of this rule fired on a
citation, and each fix was a narrower definition of EVIDENCE, never a longer
list of shapes. The list-lengthening instinct is what produced the bug each
time.

The review's last MISSED finding named the missing control — the paren tests
all surrounded matched spans with whitespace, so none covered a span sharing a
token with an id outside it. #3697-19j carries both directions now.

526 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite zero
head-only failures against a probe at upstream/next; the invariant that
`citedReqIds` is identical to upstream re-confirmed on 20,000 arbitrary
Unicode inputs.

* fix(#3697): state R4's real boundary, and stop the over-cap voice masking a drop

Two defects, both found by this round's own pre-publication body claim-audit.

1. A DEMONSTRATED drop was discarded by the unverified voice. On
   `REQ-01, REQ-02: <2049 chars>` the analyzer names REQ-02 in
   delimiterDroppedIds and the formatter then reported `req-line-unverified`,
   whose message never mentions it — the one actionable finding masked by the
   token beside it. The over-cap channel now excludes a line carrying an R4
   hit, exactly as rangeReadingOnly already did and for the same reason: that
   voice's whole claim is that nothing could be checked, and R4 has already
   checked something. The assertive channel still carries the over-cap rider,
   so nothing about the cap is traded away. Pinned by #3697-19l, which fails
   against the pre-fix build and nothing else does.

2. Three shipped artifacts asserted behaviour the code does not have — the
   same class as this PR's round-4 blocker, re-committed. CONTEXT.md's rules
   predicate, the CLI tools reference, and the warning's own advice string all
   listed markdown emphasis as an R4 trigger. It is not: styling is shaved
   BEFORE the test and tolerated around an id, never a trigger on its own, so
   `**REQ-01**, REQ-02` and `**REQ-01**; REQ-02` are both silent. The trigger
   is exactly a glued `;`/`:` or an embedded invisible.

   The census predicate was wrong in a second way. Its 26-spelling separator
   sweep found only `;` and `:` because the sweep was SYMMETRIC-ONLY and
   therefore biased: one-sided attachment drops silently for every punctuation
   outside the set — `/ | & + . > \` and the full-width and non-ASCII forms
   `; , ؛` all measured silent. The domain is wide open and R4 covers two
   characters of it. Said plainly in all three places rather than widened
   here: every previous widening of this rule first fired on a citation, so it
   is not done blind at the end of a round.

Both blind spots are now PINNED as tests (#3697-19m styling-only, #3697-19n
one-sided separators) so the documents and the code cannot drift apart again —
which is what the round-4 blocker asked for.

tests/phase.test.cjs: 542 tests, 542 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* fix(#3697): re-sweep the separator census properly, and say what it really found

The round-4 census in src/phase.cts concluded "exactly two — `; ` and `: `"
from a 26-spelling sweep. That conclusion was forced by how the sweep was
built, not by the code: it swept the ONE-SIDED form (`REQ-01; REQ-02`) for the
semicolon and colon, and only the BARE and SYMMETRIC forms (`|`, ` | `) for
every other separator. Different members of the domain were tested in
different shapes, so no other answer was reachable. Caught by this round's
pre-publication claim-audit of the response comment, reading the census
comment against its own swept list.

Re-swept fully crossed and driven through the built artifact: 21 separators x
{bare, trailing-space, leading-space, both-spaces} = 84 combinations. 26 select
both ids, 24 under-select and already warn, and 34 UNDER-SELECT SILENTLY. All
34 are one shape — a separator glued to exactly one of the two ids, e.g.
`REQ-01/ REQ-02` or `REQ-01 /REQ-02` — for every punctuation except `,` and
the `;`/`:` that R4 covers.

So R4 covers TWO CHARACTERS of a wide-open domain. That is now what the census
comment, the CONTEXT.md census-domains predicate and the CLI tools reference
all say. The set is deliberately not widened here: three successive cuts of
this rule fired on a citation, and a fourth at the end of a round with no
adversarial pass is how each of those got in.

Second false passage in the same block: styling-only decoration was described
as "left to the skipped-text rider, which names the id". A rider only exists
inside a message, and a message only exists once some rule sets `warn` — so on
a line where nothing else fires, `REQ-01, **REQ-02**` is wholly silent.
Describing it as handled reads as coverage. #3697-19m already pins the silence.

so the test matches the documented claim.

tests/phase.test.cjs: 552 tests, 552 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* chore(#3697): regenerate both CONTEXT-INDEX.json after rebasing onto next

Rebased onto next @ f4fefb0be. The two generated indexes conflicted on the
replay and were resolved by regenerating, not by hand-merging:
`npm run gen:context-index` for docs/CONTEXT-INDEX.json and
`node examples/dynamic-context-management/gen-context-index.cjs --write` for
the example's copy. Against next, each now differs only in the eight
PHASE.REQ-LINE.SEAM.* predicates this PR adds (plus the PHASE class and the
count); every base-side change (the SEAM.* predicates, the ADR-3942 value
rewrites) is carried. `lint-example-parser-parity` and
`gen-context-index --check` both pass.

* fix(#3697): an over-cap token outranks the ambiguous range voice

Round 7 review, Minor 1. `rangeReadingOnly`'s guard conjunction checked
`hasGluedRangeFragment`, `inertIdShaped` and `delimiterDroppedIds` but not
`oversizedTokens`, so a line carrying a clean, fully-selected spaced range
*and* an unrelated token past the 2048-char scan cap was coded
`req-line-range-reading` — a code CONTEXT.md's PHASE.REQ-LINE.SEAM.kinds
predicate documents as "nothing was dropped" — over a token no rule (R1-R4
all skip over-cap tokens) had ever examined. Since the PR tells machine
consumers to branch on `.code` rather than parse prose, that is a false
"nothing to verify further" signal.

The review's suggested fix was to add `oversizedTokens.length === 0` to the
conjunction. That clause is right and is here, but on its own it routes the
line to the ASSERTIVE channel: `req-line-misparse`, whose message says the
line "could not be parsed as a comma-separated REQ-ID list" on a line where
every ID present was in fact selected. That is the #2334 over-warning class
this module's own channel-selection docblock exists to prevent — a false-clean
code traded for a false-assertion one. So the correct destination is
`req-line-unverified`: the line was not CHECKED, which is not the same as
clean, and nothing on it demonstrably failed to parse either.

Both non-assertive voices were carrying their own inline copy of the same
"nothing was demonstrably dropped" conjunction, and that duplication is what
let them drift: `rangeReadingOnly` omitted the cap, while the over-cap channel
excluded a spaced range wholesale via `!hasSpacedRange`. Extract it once as
`nothingDemonstrablyDropped` and have both read it. The new predicate is a
strict superset of the old `!hasSpacedRange` guard — `spacedRangePairs.every()`
is vacuously true when no spaced range fired — so the over-cap channel's
behaviour on every line without a spaced range is unchanged, and R2 firing on
an endpoint the selector did not take still routes to the assertive channel.

Exactly one input class changes routing: a clean fully-selected spaced range
beside an unexamined over-cap token, which moves from `req-line-range-reading`
to `req-line-unverified`. Pinned by `#3697-19n` (the twin of `#3697-19l` on
the other side of the boundary — there a demonstrated drop outranks the
unverified voice, here the cap outranks the ambiguous one), with `#3697-19o`
as the negative control asserting a clean range with nothing over the cap is
still a range reading.

* docs(#3697): state the warning-code precedence, and what the cap condition actually is

Two surfaces, one point. The round 7 finding cited CONTEXT.md's
PHASE.REQ-LINE.SEAM.kinds predicate as the documentation of what
`req-line-range-reading` claims, and it was right to: that predicate said "R2
alone fired on selected endpoints; nothing was dropped" with no mention of the
scan cap, describing a line the code could not distinguish from one carrying a
token it never examined.

The range reading is the weakest of the three claims and yields to the other
two: a demonstrated drop makes the line a misparse, and a token the cap left
unclassified makes it unverified. `docs/CLI-TOOLS.md` gains that sentence; the
CONTEXT.md predicate gains it plus two precision points that this round's own
pre-push adversarial review extracted over three passes, each with a driven
counterexample I reproduced before acting on it:

  * "nothing was dropped" overstates the rule. The discriminator is RULE-scoped
    by design (round 3, Major 3), so that a parenthesised ID-shaped token does
    not re-open the #2334 over-warning class — `(REQ-02)` is indistinguishable
    from `(ADR-7)` at token level and is carried by the skipped-text rider, never
    by this code. `REQ-01, (REQ-02), REQ-03 - REQ-05` selects three, names REQ-02
    as skipped, and is still a range reading. The predicate now says "no rule
    named a dropped ID", which is what the code tests.

  * The deferral condition is `oversizedTokens` being non-empty, NOT the presence
    of a token past the cap. Those differ: a long token the selector itself took
    can be exempt, because selection is uncapped and anchored and such a token
    was therefore examined. `RANGE-01 - RANGE-05, R-<2047 sevens>` yields
    `oversizedTokens=[]` and stays a range reading. Two earlier attempts to
    characterise WHEN the exemption applies were both refuted — the neighbour
    test admits any non-short neighbour, not just a range operator — so the
    predicate now states the condition and defers the exemption's own rule to
    SEAM.cap rather than paraphrasing it a third time.

Verified after the edit: deferral holds if and only if the cap left a token
unclassified, across all three counterexamples plus controls, and an exempt
selector-taken long token is exhibited. No behaviour change — predicate text,
one CLI-reference paragraph, and the two regenerated indexes. Predicate count
unchanged at 285 across 22 classes, 0 duplicate ids; lint-example-parser-parity
and both `--check` generators pass.

* test(#3697): rename the round 7 regression pair — 19n was already taken

Self-found immediately after the push, before anything was published to the
review thread. The two tests added this round were named `#3697-19n` and
`#3697-19o`, and `#3697-19n` was already in use: it is the declared-blind-spot
case for one-sided separators in both attachment directions, generated inside a
loop with a computed label, which is why a grep for a literal `test('#3697-19n'`
did not find it. The PR body's own *Declared blind spots* list already refers to
`#3697-19n` with that meaning.

Nothing failed. Duplicate test names do not error, and the suite stayed green at
567/567 — which is the argument for fixing it rather than against. Two concrete
costs: any TAP name-set differential collapses same-named tests under `sort -u`,
so one of the two becomes invisible to exactly the did-not-run and pass->fail
checks that name-set comparison exists to perform; and a reviewer reading
"#3697-19n" in the body now gets a different test than the one the body means.

Renamed to `#3697-19p` (over-cap beside a clean range) and `#3697-19q` (its
negative control), the next free ids in the series; the pre-existing `#3697-19n`
is untouched at its original 4 occurrences. Cross-references inside the renamed
block were updated with them. Negative control re-run under the new ids: 19p
still fails against pre-fix source and passes after, 19q passes at both ends.

### The ROADMAP `**Requirements**:` line grammar
`phase complete` reads each phase's `**Requirements**:` line to decide which
REQ-IDs to mark. The grammar is deliberately small, and it is documented here
because the command now warns about it (#3697) — a warning about a rule that
cannot be looked up is not actionable.
**The canonical form is a comma-separated list of REQ-IDs.** Square brackets are
optional; a REQ-ID is `PREFIX-N`, where the prefix is a letter followed by
letters or digits. Two tolerances are worth knowing because the warnings below
do **not** fire on them: the line is split on commas *and whitespace*, so
`REQ-01 REQ-02` selects both; and the ID shape is matched case-insensitively,
so `req-01` is selected and marked. Write the comma list anyway — it is what
every template and every example uses — but neither spelling is an error:
```
**Requirements**: REQ-01, REQ-02, REQ-03
**Requirements**: [REQ-01, REQ-02, REQ-03]
```
**Ranges are not expanded** — `REQ-01 … REQ-05` selects the two endpoints and
nothing between them, and `REQ-01..REQ-05` selects nothing at all, because the
whole token fails the ID shape. This is a deliberate non-feature, not an
oversight: the line is a traceability record, and silently inventing IDs that
appear nowhere in `REQUIREMENTS.md` is worse than declining to.
**A deliberately empty line is written `TBD` or `None`.** Those two words are
the placeholder vocabulary, and they are matched as the line's leading token, so
`None (per ADR-7)` and `**None**` are declared-empty too. **Any other wording
that selects no REQ-IDs warns** — `Deferred`, `N/A`, `Pending`, `TBA`, a bare
`-`, or free prose — because from the command's side an unrecognised word is
indistinguishable from a line that was meant to cite requirements and failed
to. A line whose only content is an HTML comment is not "other wording" and
stays silent, so the shipped template's own `<!-- ... -->` does not warn.
**Write each requirement as a bare ID, separated by a comma.** The line is
split on commas and whitespace only, and nothing else is stripped, so anything
attached to an ID takes the ID with it. `REQ-01; REQ-02` marks **only**
`REQ-02`; so do `REQ-01 ;REQ-02`, `**REQ-01;** REQ-02` and an ID carrying a
stray invisible character. Those are the cases the warning names — it reports
the dropped ID, because this is the quietest way to lose a requirement here
(the command reports `requirements_updated: true` either way).
**What the warning does NOT reach.** Stated so its silence is not read as a
clean bill, and enumerated rather than summarised, because each of these is a
requirement that goes missing without a word. The check fires only when the
thing touching the ID is a `;`, a `:`, or an invisible character:
- **Markdown styling on its own is silent.** `**REQ-01**, REQ-02` drops
`REQ-01` and says nothing at all. Styling is not evidence that a separator
was meant. `**REQ-01**; REQ-02` is silent for the same reason — the `**`
sits between the ID and the `;`, so nothing is touching the ID.
- **Any other attached punctuation is silent.** `REQ-01/ REQ-02`,
`REQ-01| REQ-02`, `REQ-01. REQ-02`, `REQ-01+ REQ-02`, `REQ-01> REQ-02` and
their full-width and non-ASCII equivalents (`;`, `,`, `؛`) each mark only
`REQ-02`. A fully crossed sweep — 21 separators against bare, leading-space,
trailing-space and both-spaces spellings, 84 combinations — found **34**
silent under-selections, every one of them a separator glued to exactly one
of the two IDs. Only `;` and `:` are in the set. Widening it is a live
option — say the word — but each past widening of this check first fired on
a citation, so it is not done blind.
- **A dropped ID whose prefix matches nothing selected is silent.**
`REQ-01, REQ-02: login` is reported; `REQ-01, FOO-02: x` is not. A citation
is textually identical to a dropped requirement — `REQ-01, see ADR-7:
section 3` carries `ADR-7:` in exactly the shape `REQ-01;` has — and prefix
agreement is the only thing that separates them without guessing at prose.
Anything inside matched parentheses is left alone for the same reason:
`(see ADR-7: section 3)` is a citation.
The prefix gate is not complete in the other direction either: a citation that
*shares* a selected prefix — `REQ-01, see REQ-7: sec 3` — does warn, naming
`REQ-7` as dropped. Nothing at the token level separates that from a real
drop.
**Dash spellings need a full ID on both sides.** `REQ-01-REQ-05` reads as a
range; `REQ-01-05` does not, and neither does any of its typographic variants
(en dash, em dash, minus sign, and the rest). The reason is that
`PREFIX-<digits><dash><digits>` is also a date (`FY-2026-08`) and a sub-numbered
ID (`API-2-01`), so warning on it would be noise on lines that are perfectly
correct. `..`, `…`, `to`, `thru` and `through` have no such reading and do
accept a bare numeric endpoint (`REQ-01..05`). The cost is that
`REQ-01, REQ-02-05` is not reported; a bare `REQ-02-05` still is, because it
selects nothing.
**What warns, and in which of the three voices.** All go to `warnings[]` and
none blocks completion:
- *"could not be parsed as a comma-separated REQ-ID list"* — the line did not
yield the requirements it appears to name. That covers two cases, and the
message says which one it is: ID-shaped text on the line was **not**
selected, so something was demonstrably dropped; **or** the line selected
nothing at all while not being a `TBD`/`None` placeholder, in which case
there may be no ID-shaped text on it whatsoever (`Deferred` takes this
voice). Either way nothing was marked and the line needs fixing.
- *"contains what reads as a range between two cited REQ-IDs"* — the separator
is the only thing in question: a separator between two cited IDs could equally
be a range or an annotation, and the command cannot tell them apart, so it
states both readings rather than asserting a failure that may not have
happened. It speaks about the **separator**, not about the whole line. It is
also the *weakest* of the three claims, so it yields to the other two: a
demonstrated drop elsewhere on the line makes it a misparse, and an
unexamined over-cap token makes the line unverified — a voice whose claim is
that nothing was dropped cannot speak over a token no rule read.
**Each warning carries a machine-readable kind.** The prose goes to
`warnings[]` as before — that field is unchanged and is still an array of
strings — and the kind is emitted beside it as `requirements_line_warning`,
one of `req-line-misparse`, `req-line-range-reading` or `req-line-unverified`.
The field is absent entirely when the line is clean. Key on the kind rather
than on the wording; the wording is free to improve.
Either of those two voices may add a factual note naming **ID-shaped text on the
line that was not selected**. Square brackets *are* stripped — `[REQ-01, REQ-02]`
is the documented form — but parentheses are not, so `(REQ-02)` is not marked.
The command cannot tell that from `(ADR-7)`, which is a citation and correctly
ignored, so it names what it skipped and leaves the judgement to you. Where the
skipped text is `PREFIX-<digits>-<digits>` — the shape the dash rule above
declines to adjudicate, because `FY-2026-08` is a date and `API-2-01` is a
legal requirement id and no rule separates them — it is still named, with that
ambiguity stated alongside it. Naming it and saying why it is ambiguous beats
both alternatives: filtering it hides a real dropped requirement, and reporting
it bare asks you to check whether a date is a requirement.
The third voice is for input the command could not examine: *"could not be
checked ... the REQ-ID selection on this line is unverified"*. Range detection
is bounded at 2,048 characters per token, so a longer token is not classified —
and unclassified is reported, never treated as clean. Selection itself is *not*
bounded, so a valid REQ-ID longer than that is still selected and marked
normally; it only triggers this voice if something beside it could have formed a
range with it, which is the case where the bound actually suppressed a check.

* CENSUS (round 4): the domain is "separators an author writes between two

* censused above, and it had no census at all before this round.
*
* ROUND 4'S CENSUS WAS WRONG, AND THE WAY IT WAS WRONG IS THE LESSON. It swept
* 26 spellings and concluded "exactly two — `; ` and `: `". It reached that
* answer because it swept the ONE-SIDED form (`REQ-01; REQ-02`) for the
* semicolon and colon, and only the BARE and SYMMETRIC forms (`|`, ` | `) for
* every other separator. Different members of the domain were tested in
* different shapes, so the conclusion could not have come out any other way.
*
* Re-swept round 5, fully crossed: 21 separators x {bare, trailing-space,
* leading-space, both-spaces} = 84 combinations, driven through the built
* artifact. 26 select both IDs, 24 under-select and already warn, and
* 34 UNDER-SELECT SILENTLY. All 34 are the same shape — a separator glued to
* exactly ONE of the two IDs, e.g. `REQ-01/ REQ-02` or `REQ-01 /REQ-02` — for
* every punctuation except `,` (the real delimiter) and `;` / `:` (R4).
* Measured silent: | / + & \ > . ! ? • · ؛ ; , - ~ and the word operators
* `and` / `plus` in trailing-space form.
*
* So the honest statement is that R4 covers TWO CHARACTERS of a domain that is
* wide open, not that the domain has two members. The round-4 review
* hand-listed the semicolon; the colon is its sibling and fails identically;
* everything else in that list is disclosed here and NOT caught. Widening the
* delimiter class is a small change and deliberately not made at the end of a
* round: three successive cuts of this rule fired on a citation.
*
* THE GATE IS ADJACENCY, and it is the part to read. Styling is stripped, then
* the delimiter must be touching the id: `REQ-01;`, `;REQ-02`, `**REQ-01;**`
* and the backticked form all qualify. `**REQ-01**;` does NOT — outside the
* styling a `;` is sentence punctuation, which is why `REQ-01, see **REQ-7**;
* next topic` is a citation and not a drop. An INVISIBLE anywhere in the token
* qualifies without an adjacency test, because nobody types one on purpose, so
* it is corruption rather than intent.
*
* Markdown styling on its own is NOT a trigger and NOT reported. It reaches
* the skipped-text rider, which names the id without asserting a drop — but a
* rider only exists inside a MESSAGE, and a message only exists when some rule
* set `warn`. On a line where nothing else fires, `REQ-01, **REQ-02**` is
* wholly silent. Saying it is "left to the rider" reads as coverage and is
* not; #3697-19m pins the silence so this comment cannot drift back.
*
* NOT reached, stated rather than fixed, and the second member is WIDER than
* this comment first claimed:
* - anything inside a parenthetical. A parenthesis is this rule's citation
* MARKER, never decoration to shave — `(REQ-02)` and `(ADR-7)` are the
* same shape and the rule declines both.
* - a decorated id whose prefix is on NO selected id: `REQ-01, FOO-02: x`
* stays silent even when FOO-02 is real. Prefix agreement is what
* separates a drop from a bare citation — `REQ-01, see ADR-7: section 3`
* carries `ADR-7:` in exactly `REQ-01;`'s shape — and it is the module's
* own idiom, not a new heuristic (reqEndpointsImplyInterior already
* requires an agreeing prefix). The gate is NOT complete: a citation that

* So the ambiguity is DISCLOSED rather than decided —
*
* * any rule other than R2 fired, or R2 fired on an endpoint that was not
* selected → something ID-shaped was demonstrably NOT taken. The line did
* fail to parse; say so plainly, as before.
