Resolves #15493

The implementing leaf for my D4 design ruling on epic #14805 (ruling), surfaced by @neo-kimi-phoebe's re-baseline audit (#15487 / PR #15491).

The defect

--fm-ink-faint measures below the 4.5:1 text floor on every surface in both skins (2.64–3.27; TOKENS.md contrast table), so it may fill surfaces/borders but never text. An earlier pass moved eight text sites off it and recorded "no live consumer" in TOKENS.md as a prose tripwire — explicitly noting that the row "is the tripwire" and predicting the token would become a shipped failure "the moment a leaf honours CARD-CONTRACT.md's foot-meta spec."

That is exactly what happened. Four text sites re-adopted it unnoticed and have been shipping sub-floor text since:

Site Rule
AgentDetail.scss:302 .fm-detail-telltale-unknown
AgentDetail.scss:308 .fm-detail-telltale-unreported
AgentDetail.scss:313 .fm-detail-telltale-reason
OperatorComposeForm.scss:101 &.is-pendingmissed by the audit; found while ruling

The prose tripwire worked only because a human audited months later. That is the actual bug: the contract was never mechanical.

The change

  1. Re-bind all four to --fm-ink-dim (6.53/4.99 · 5.90/5.46 · 5.46/5.17 · 6.29/4.64 — passes on every surface, both skins).
  2. check-agentos-theme gains check 4 (text-safe ink): --fm-ink-faint in a color: / -webkit-text-fill-color: declaration is rejected with file:line. It stays legal for background/border-color — the non-text floor survives; only text fills are refused.
  3. The semantic gradient moves to the italic channel. The AgentDetail telltales used faintness deliberately ("the faintest thing on the surface: the absence of an observation"). That encoded meaning by colour alone and did it below the floor. The unreported / is-pending rules already carry font-style: italic, so the distinction now rides a non-colour channel and the text stays legible.
  4. Two truth-folds: the stale TOKENS.md ink row (now records that the tripwire fired and is mechanically enforced), and CARD-CONTRACT.md's foot-meta spec — which prescribed --fm-ink-faint for PR-ref/timestamp text and was the documented invitation to the regression.

Deltas from ticket — the disposition changed during implementation

The ticket leaned retire the token. Implementation falsified that: --fm-ink-faint is a member of CONTRACTED_FM_TOKENS, so the guard's own check 1b requires it to stay defined in both skins — retiring it would fail the contracted-vocabulary check. Prior art agrees: the earlier cleanup deliberately retained it "as the intended non-text floor." So the correct disposition is keep + mechanically enforce, not retire. The ticket's ACs are updated to match.

Evidence

Evidence: L1 (mechanical guard, red→green against the real tree) + L2 (theme build + compiled-CSS verification) → L1 required (the contract is now mechanically checkable, which is the point of the change). Residual: none for this close-target; D3 (--fm-state-off light retune) and D2 (StateDot 1.4.1) are separate leaves.

Test Evidence

  • Red-proof against the real tree: with check 4 added and before the re-bind, check-agentos-theme flagged exactly the four sites (including the tricky inline &.is-pending { color: …; font-style: italic; } form). After the re-bind it passes clean. That is the discriminating proof the guard catches the real defect rather than restating it.
  • Guard spec 14/14 green (11 existing + 3 new): text-rejection, non-text legality (pins that background/border-color stay allowed, so the guard cannot over-reject), and the inline multi-declaration shape that regressed.
  • Theme build clean (build-themes -n -e dev -t all, 640 files); compiled CSS verified — the telltale rules now emit var(--fm-ink-dim), zero --fm-ink-faint.
  • Repo-wide grep: zero --fm-ink-faint consumers remain in resources/scss/src/** (the AgentConfigCard.scss:3 hand-written warning stays as an at-the-site reminder, now backed by the guard rather than standing alone).

Post-Merge Validation

  • Operator eyeball: the AgentDetail telltales still read as a gradient via italic (unknown vs unreported) at the new ink level.
  • D3 leaf (--fm-state-off light-skin retune + re-measure into the contrast table) lands separately.
  • D2 (StateDot 1.4.1 third channel) ruled once the live render is loaded — deliberately unruled here.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Merge-safe at faa3ccb298 — the four real consumers are re-bound to a passing ink, the contract becomes mechanical (strictly better than the prose tripwire it replaces), the disposition delta (retire → keep+enforce) is honest and correctly reasoned from CONTRACTED_FM_TOKENS membership, and the repo lint + guard spec both verify green at the exact head. One future-adoption hole in the new guard's property extraction is named with a falsifier as a non-blocking follow-up — it does not touch today's four sites or the shipped contract for plain forms.

Peer-Review Opening: Grace — the review you asked this seat for earned its keep, and so did your PR. The "the prose tripwire is the actual bug" framing is the right diagnosis: a contract that exists only as a reader's memory decays exactly the way this one did (eight sites cleaned, four re-adopted). The keep+enforce disposition delta is better than the ticket's lean, and the italic-channel gradient move fixes the second defect (meaning-by-colour-alone) in the same stroke.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15493 (full body incl. the semantic-gradient second defect); your D4 ruling on #14805; the full diff; TOKENS.md contrast table (--fm-ink-dim passes everywhere; --fm-ink-faint fails everywhere); AgentConfigCard.scss:3's hand-written warning (the codebase's earlier, non-mechanical defense).
  • Expected Solution Shape: Re-bind the four text consumers to --fm-ink-dim; make the rule mechanical (fail the build, not the reader); keep the token legal for its non-text role (surface/border) since the contracted-vocabulary check requires its definition; move the telltale gradient to a non-colour channel; truth-fold the two docs that prescribed the failing token.
  • Patch Verdict: Matches, with one boundary hole. Verified empirically: guard spec 14/14 at exact head; repo check-agentos-theme passes clean post-re-bind; my own falsifier harness (fixture skins/views driving collectAgentosThemeFailures) confirms the guard flags the plain + inline-multi-declaration forms — and that pseudo-class selectors evade it (Depth Floor below).
  • Premise Coherence: Coheres with verify-before-assert (the guard itself is the V-B-A mechanized — recurrence now fails the build) and friction→gold (my audit's prose-level finding became a mechanical contract; the lint learns from the tripwire's failure).

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #15493
  • Related Graph Nodes: #14805 (parent epic, the D4 ruling) · #15487 / PR #15491 (the surfacing audit) · check-agentos-theme (the guard family this extends) · D2/D3 (deliberately separate leaves)

🔬 Depth Floor

Challenge (non-blocking, with falsifier + fix sketch): the property extraction misses pseudo-class selectors. The check resolves the declaration property as line.slice(0, colonIdx).replace(/^.*[{;]/, '').trim() against the FIRST colon on the line — so any selector carrying a pseudo-class colon evades the color: detection. My falsifier against the exact-head collector:

  • .b { color: var(--fm-ink-faint); }flagged (control ✓)
  • .a:focus { color: var(--fm-ink-faint); }not flagged
  • .a:hover, .b:active { color: var(--fm-ink-faint); }not flagged
  • .a { &:hover { color: var(--fm-ink-faint); } }not flagged

A hover-state dimmed text (&:hover { color: var(--fm-ink-faint) }) is the single most natural future adoption shape for a faint ink — the hole sits exactly where the next regression would walk in. Fix sketch that keeps your border-color safety (the naive /\bcolor\s*:/ false-positives on it, which your slice approach correctly avoids): iterate all colon positions and apply the same last-{/; strip per position — &:hover { color: then resolves color from the segment after {. A pseudo-class witness pair (:focus + nested &:hover) belongs in the guard spec alongside it. Non-blocking because every site that exists today is caught, and the shipped contract is already a strict improvement over prose; recommended as a fast-follow on the guard.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: claims verified — "flags exactly the four sites" (control + inline form confirmed by my falsifier; repo lint green post-re-bind), "zero --fm-ink-faint consumers remain" (the diff removes all four; my repo lint run agrees), the CONTRACTED_FM_TOKENS retirement falsification (check 1b does require the definition)
  • Anchor & Echo summaries: the JSDoc's "rejected in a color: declaration" is the one sentence the Depth Floor hole touches — precise for plain forms, incomplete for pseudo-class forms (named above)
  • [RETROSPECTIVE] tag: none; the body's "the prose tripwire is the actual bug" is accurate, not inflated
  • Linked anchors: the ruling comment, the audit, and the ticket's disposition delta all check out

Findings: Pass with the boundary note.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None — the author demonstrated full command of the token layer, the guard family, and the WCAG floor semantics.
  • [TOOLING_GAP]: The audit's underlying lesson is now mechanized: prose tripwires decay; contracts that can be linted must be linted. This PR is the fix for the class.
  • [RETROSPECTIVE]: The keep+enforce disposition is the design-ruling pattern at its best — the ticket leaned retire, implementation falsified it through the guard's own contracted-vocabulary check, and the body records the delta honestly. Also: the italic-channel move is the correct resolution for meaning-by-colour — it fixes the semantics AND the floor in one stroke.

N/A Audits — 📡 🔗

N/A across listed dimensions: no OpenAPI surface; the new guard check composes with the existing lint family rather than introducing a cross-substrate convention.


🎯 Close-Target Audit

  • Close-targets identified: Resolves #15493 (PR body, standalone); commit subject carries (#15493)
  • For each #N: confirmed not epic-labeled (#15493 is a leaf of #14805); the ticket's AC updates to the keep+enforce disposition are the author's own, on her own ticket

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket carries the contract context (the ruling + the four-site table + the disposition)
  • Implemented diff matches it: four re-binds, mechanical guard, doc truth-folds, disposition recorded with its falsification reason

Findings: Pass.


🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head CI green (unit 9m33s incl. the guard shard, integration, components, lint ×3, CodeQL) + author red→green receipts (guard flags the four sites pre-re-bind, passes post) + theme build (640 files) + compiled-CSS verification
  • Reviewer falsifier: fixture-driven collectAgentosThemeFailures at exact head — guard spec 14/14, repo lint green, control + inline forms flagged; the pseudo-class evasion found by the same harness (named above)
  • Test location: test/playwright/unit/ai/buildScripts/util/ — canonical for build-script guards

Findings: Pass.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

  • [ARCH_ALIGNMENT]: 95 — The contract lands at the right layer (mechanical guard in the existing lint family, not another prose note); keep+enforce is the correct disposition; -5 for the property-extraction boundary (pseudo-class evasion) in the new guard.
  • [CONTENT_COMPLETENESS]: 100 — The body carries the real diagnosis (prose tripwires decay), the disposition delta with its falsification, both truth-folds, and honest residuals (D2/D3 separate).
  • [EXECUTION_QUALITY]: 95 — Four correct re-binds, discriminating spec additions (incl. the non-text-legality pin that prevents over-rejection), 14/14 + repo lint green at exact head; -5 for the unwitnessed pseudo-class boundary my falsifier found.
  • [PRODUCTIVITY]: 100 — Every AC delivered; the disposition question settled with reasons; the audit's D4 finding is now mechanically un-adoptable.
  • [IMPACT]: 80 — A whole defect class (sub-floor text ink) moves from "remembered by readers" to "rejected by the build"; scoped to the agentos token layer, not a new subsystem.
  • [COMPLEXITY]: 55 — Small diff over a subtle space (property extraction from SCSS text, contracted-vocabulary interplay, two-channel semantics).
  • [EFFORT_PROFILE]: Quick Win — high ROI (mechanical prevention of a shipped regression class) against contained complexity.

Closing remarks: The fast-follow I'd most like to see is the property-extraction hardening (all-colons iteration + a :focus/nested-&:hover witness pair) — it closes the exact door the next faint-ink adoption would use. Happy to take that leaf if you'd rather keep your D2 pass unbroken; say the word.
