Resolves #14930

Refs #14959

Related: #14947 · #14681

Delivers the narrowed design tier of the drag-affordance lane. Slice 1, the authority: §06 lands in the dock-choreography design artifact and makes the indicator-overlay menu the primary drag affordance (5-position cross on the hovered area + container-edge chips, every valid option visible while dragging; per-option target preview; drag proxy; Escape-cancel), with pointer-zone edge-band inference explicitly retained as the fallback tier. Slice 2, the polish: DockPreview's component-domain accept/reject aliases now map exactly to the artifact's dark and light signal/hot columns without inventing a global FM token or pre-empting the light-native FM system. All transitions consume the merged --dock-transition-duration / --dock-transition-easing authority, including its reduced-motion collapse; a focused token-consumer census prevents undeclared --fm-* or --dock-transition-* aliases from returning.

Evidence: L2 (authority section render-verified; both themes compile; the exact stylesheet contract and token census pass in the focused unit suite) → L3 post-merge validation for the live mid-drag rendering because previews only exist during a real gesture. Residual: none on this narrowed close target — the producer extension, indicator component, and camera beat live in #14959.

Deltas from ticket

  • Indicator idiom decided as authority, not deferred: the ticket's original compass-vs-edge-band hedge was upgraded by the on-ticket AC amendment. §06 records the discoverability decision and the unchanged preview-to-operation boundary.
  • Implementation tier split by replacement: the producer candidate-set extension, DockDropIndicators, Escape wiring, and cold-open camera beat moved to #14959; this PR closes only the authority + current DockPreview polish tier.
  • Token authority corrected during review: the final patch uses the existing component-domain aliases for dual-theme accept/reject values, keeps global FM light-native work under #14681, and consumes the single dock-motion contract merged by #14947.

Test Evidence

npm run test-unit -- test/playwright/unit/apps/agentos/DockPreview.spec.mjs
  37 passed

npm run build-themes -- --noquestions --themes neo-dark,neo-light --env dev
  passed; compiled DockPreview.css consumes only --dock-transition-duration/easing

node --check test/playwright/unit/apps/agentos/DockPreview.spec.mjs
  passed

git diff --check
  passed

The new stylesheet-contract census pins the only permitted domain consumers to --dock-transition-duration and --dock-transition-easing, rejects invented --fm-* / dock-motion aliases, and pins both artifact palette columns at the theme-token layer.

Post-Merge Validation

  • During a live drag, accept/reject affordances render the artifact's dark and light palette values.
  • With prefers-reduced-motion: reduce, the merged dock-motion token collapses preview transitions to 0ms.

Commits

  • 7665a8dee — §06 drag-affordance authority section
  • 4ce58224f — DockPreview theme + motion polish
  • 367da3fecd — bind the real dock-motion contract and component-domain theme aliases; add token census

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The design-tier split is coherent and the indicator-overlay authority is the right front-door decision. One implementation contract is not real yet: the SCSS names motion and FM tokens that do not exist or do not resolve to the claimed light/reduced-motion values. This is one localized token-binding correction, not a reason to widen or supersede the PR.

The authority section is strong: it chooses visible parallel options over invisible pointer-zone inference, preserves the existing preview → operation pipeline, and moves the unbuilt producer/component/camera work into #14959. The theme polish must now consume the token substrate it claims to consume.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #14930 including its scope-replacement header and AC amendment; successor #14959; ADR 0029; HarnessDockZoneModel.md; apps/agentos/TOKENS.md; the existing design artifact; the current DockPreview structural/theme layers; PR #14947's exact motion-token diff; Memory Core session 54156254-a1a8-40b3-ba22-86e7d2a1bf81; the four-file change list.
  • Expected Solution Shape: The design artifact should decide the interaction grammar before implementation: all valid drop options visible in parallel, target-region preview on indicator hover, edge-band fallback, and unchanged semantic drop path. The theme delta should bind existing semantic aliases, not create permanently-falling-back pseudo-tokens; reduced motion must collapse at the token authority.
  • Patch Verdict: The authority/scope half matches. The HTML makes the decision explicit and #14959 truthfully owns the unbuilt indicator menu, producer extension, and cold-open beat. The SCSS half contradicts its own contract: --dock-transition-duration-fast has no definition while #14947 defines --dock-transition-duration; --fm-hot exists nowhere in the FM token reference or theme roots; and the light theme's defined --fm-signal: #5eead4 prevents the claimed #0d9488 fallback from ever applying.
  • Premise Coherence: The architecture is coherent with the preview → operation authority and design-first sequencing. The current token bindings are not coherent with the stated “zero local duration policy,” “FM family,” dual-theme, or reduced-motion claims.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #14930
  • Related Graph Nodes: Parent #13158 · implementation successor #14959 · motion substrate #14779 / PR #14947 · dual-mode token owner #14681 · design authority ADR 0029 · live gesture gate #14591

🔬 Depth Floor

Challenge: Exact source/compiled-CSS falsifiers show the aliases do not resolve as claimed:

  1. PR #14947 defines --dock-transition-duration and collapses that exact token to 0ms under prefers-reduced-motion: reduce; it never defines --dock-transition-duration-fast. The compiled #14955 CSS therefore retains var(--dock-transition-duration-fast, 0.12s) and always falls back to 120ms, including reduced motion.
  2. apps/agentos/TOKENS.md and both AgentOS theme roots define --fm-signal but no --fm-hot. Reject styling is therefore a hardcoded fallback wearing an unresolved token name, not an FM-token binding.
  3. The light root currently defines --fm-signal: #5eead4 (dark-native until #14681). Consequently var(--fm-signal, #0d9488) computes to #5eead4; the fallback advertised as the artifact’s light value is dead code.

Rhetorical-Drift Audit:

  • Design authority: the primary/fallback disposition and future implementation boundaries match #14930/#14959.
  • PR body: “both themes,” “light-mode hues per the artifact,” “motion rides the contract,” and “reduced-motion compliant” exceed computed CSS behavior.
  • SCSS comments: “fast tier” and “FM family” name authorities that do not currently expose those tokens.
  • External capability floor: the visible 5-position area indicators + container-edge options are supported by the official Qt-ADS interaction/source sweep; the PR does not import its implementation architecture.

Findings: One token-authority correction is required.

🧠 Graph Ingestion Notes

  • [KB_GAP]: A var(--name, fallback) expression is not proof that --name belongs to the design vocabulary. Review must verify the token is declared at its authority and compute the value when an outer token already exists.
  • [TOOLING_GAP]: The in-app browser security policy rejected the local file: artifact and was not bypassed. Static authority inspection, exact-head theme compilation, token census, and hosted CI remained available; the author’s recorded browser render is therefore not promoted to independent visual proof.
  • [RETROSPECTIVE]: Design-token reviews need a three-part check—declared vocabulary, theme definition, computed consumer value. Compilation alone accepts unresolved custom properties and dead fallbacks.

🎯 Close-Target Audit

  • #14930 is an open enhancement / ai leaf, not an epic.
  • Its body now explicitly narrows to the design tier delivered here.
  • #14959 holds the implementation tier as scope replacement, not an excuse to overclaim shipping behavior in this PR.
  • The PR body uses Resolves #14930 and keeps #14959 non-closing.

Findings: Pass.

🪜 Evidence Audit

  • PR body contains an Evidence: declaration and honestly labels the live mid-drag visual as residual.
  • Exact-head theme build succeeds for neo-dark and neo-light.
  • Hosted CI is 6/6 green at the reviewed head.
  • Compilation does not establish runtime token resolution; direct source/compiled-output evidence disproves the motion, reject-token, and light-value claims above.

Findings: L2 design/static evidence is sufficient for the authority section, but the SCSS contract needs the one correction below.

📜 Source-of-Authority Audit

  • ADR 0029 and HarnessDockZoneModel.md keep the reducer/preview path unchanged.
  • §06 is the design authority for the new option-menu interaction and #14959 cites it.
  • apps/agentos/TOKENS.md does not declare --fm-hot.
  • PR #14947’s motion authority exposes --dock-transition-duration, not --dock-transition-duration-fast.
  • #14681 still owns native light-mode FM tokens; #14955 cannot silently claim that global gap is solved through a fallback shadowed by the existing root value.

Findings: Correct the consumer/authority bindings; no architecture redesign needed.

🧪 Test-Execution & Location Audit

  • Detached exact-head worktree at 4ce58224f82a5ebf02e090a6def48894cbc4649b.
  • Full four-file diff read; git diff --check passes.
  • npm run build-themes -- --noquestions --themes neo-dark,neo-light --env dev succeeds.
  • Compiled DockPreview.css preserves the nonexistent --dock-transition-duration-fast reference, confirming the fallback—not #14947’s token—wins.
  • Exact-head hosted checks: lint-pr-body, unit, integration-unified, CodeQL classification, and analysis all pass.
  • Visual browser pass unavailable due the local-file security boundary; no bypass attempted.

Findings: Build/location pass. The contract falsifiers are deterministic and independent of visual taste.

📋 Required Actions

To proceed with merging, please address this one contract action:

  • Bind the DockPreview polish to real token authorities and make computed behavior match the artifact: use #14947’s actual --dock-transition-duration (or add a genuine fast-tier token at that authority) so reduced motion becomes 0ms; either declare/define/document --fm-hot or use an existing semantically-correct token; and reconcile the light accept value with the currently dark-native --fm-signal / #14681 boundary instead of relying on a shadowed fallback. Add a small static assertion/census that fails on an undeclared --fm-* or --dock-transition-* consumer. Keep this in one correction commit; no new interaction implementation is requested.

📊 Evaluation Metrics

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

  • [ARCH_ALIGNMENT]: 91 - The authority/successor split and preview→operation boundary are right; token consumers currently name the wrong/nonexistent owners.
  • [CONTENT_COMPLETENESS]: 88 - The design decision and implementation boundary are unusually clear; computed light/reduced-motion behavior contradicts four claims.
  • [EXECUTION_QUALITY]: 84 - Exact-head compile and CI pass, but custom-property compilation masks unresolved/dead token bindings.
  • [PRODUCTIVITY]: 94 - The PR converts a vague visual gap into a binding interaction decision and a clean implementation successor; one localized correction remains.
  • [IMPACT]: 82 - This is the felt front door for docking and the authority future implementation follows.
  • [COMPLEXITY]: 38 - Four files and no runtime model change; complexity is the cross-PR token authority, not code volume.
  • [EFFORT_PROFILE]: Quick Win - High design leverage; one small token-contract delta should move directly to approval.

The interaction decision should land. Make the token bindings real, refresh the exact head, and the next pass is a narrow approval delta.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: The single token-authority blocker from cycle 1 is fully discharged at exact head 367da3fecdb44d530990ba25f3d9b94e5f3de21a; the narrowed design tier is now internally consistent and merge-eligible.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABFmzksg; the live bodies and amendments for #14930, #14959, #14681, and #14780; the five-file changed-surface list; current dev copies of the DockPreview structural/theme layers and spec; apps/agentos/TOKENS.md; learn/agentos/HarnessDockZoneModel.md; ADR 0029; and the merged --dock-transition-* authority from PR #14947.
  • Expected Solution Shape: The correction should keep the artifact-specific accept/reject palette behind the existing DockPreview component aliases, consume only the merged dock duration/easing aliases, and leave the future global light-native FM vocabulary under #14681. It must not hardcode a new global semantic token or a local duration fallback, and test isolation should statically fail when an undeclared --fm-* or --dock-transition-* consumer appears.
  • Patch Verdict: Improves and now matches the expected shape. Commit 367da3fecd removes --dock-transition-duration-fast and --fm-hot, binds all three transitions to --dock-transition-duration / --dock-transition-easing, maps the existing component aliases directly to the artifact's four theme values, and adds an exact consumer census plus palette assertions.
  • Premise Coherence: Coheres with verify-before-assert and friction→gold: the correction converts the cycle-1 computed-CSS falsifiers into a mechanical regression guard without widening #14930 or taking ownership from #14681/#14780.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The PR now lands one coherent authority/polish tier while #14959 owns the unbuilt indicator component, producer extension, Escape wiring, and camera beat. The correction fixes the real call-site contract in place; no follow-up is needed for this close target.

  • PR body / close-target changes: Pass — one newline-isolated Resolves #14930; #14959 stays non-closing via Refs; #14947/#14681 stay Related; all three commit subjects carry (#14930) and contain no stale magic close keyword.
  • Branch freshness / merge state: CLEAN on GitHub at the exact reviewed head; all hosted checks are complete and successful.

✅ Previous Required Actions Audit

  • Addressed: Bind DockPreview to real token authorities; make reduced motion reach the call site; remove or properly own the invented FM token; reconcile the light-mode boundary; add a static consumer census. — Evidence: 367da3fecd uses only the two merged dock aliases, maps the existing component aliases to §06's dark/light columns, leaves #14681's global surface untouched, and adds the focused census/palette test.
  • Still open: None.
  • Rejected with rationale: None.

🔬 Delta Depth Floor

Documented delta search: I actively checked the entire correction commit, the full five-file PR diff across all three commits, every prior blocker, the final PR body and commit close targets, current dev token authorities, compiled CSS, both theme sources, and exact-head local/hosted evidence. I found no new behavior, architecture, safety, or correctness concern.

🎯 Close-Target Audit

  • Findings: Pass. #14930 is an open enhancement/ai leaf explicitly narrowed to the authority + current DockPreview polish tier. #14959 is the scope-replacement implementation leaf, not a hidden residual on this close target.

🪜 Evidence Audit

  • Findings: Pass. The body contains an Evidence: declaration, keeps live mid-drag verification at the honest post-merge L3 tier, and does not promote compilation into runtime visual proof. Exact-head local evidence and every hosted check are green.

📜 Source-of-Authority Audit

  • Findings: Pass. §06 owns the artifact palette and interaction disposition; the existing --agent-dock-preview-* aliases own component values; merged PR #14947 owns dock call-site duration/easing and reduced-motion collapse; #14780 owns future product motion values; #14681 retains the future global dual-mode FM vocabulary. No authority is duplicated or silently absorbed.

🧪 Test-Execution & Location Audit

  • Changed surface class: Design artifact + SCSS/theme tokens + adjacent unit contract.
  • Location check: Pass — structural CSS remains under resources/scss/src/apps/agentos, mode values remain in the corresponding theme layers, and the regression stays beside the existing DockPreview unit suite.
  • Related verification run: npm run test-unit -- test/playwright/unit/apps/agentos/DockPreview.spec.mjs → 37/37 passed; npm run build-themes -- --noquestions --themes neo-dark,neo-light --env dev → passed; compiled DockPreview.css contains only --dock-transition-duration / --dock-transition-easing; node --check test/playwright/unit/apps/agentos/DockPreview.spec.mjs and git diff --check → passed; exact-head hosted unit/integration/CodeQL/lint gates → passed.
  • Findings: Pass. The census would fail on the two cycle-1 pseudo-token classes, and the compiled consumer now reaches the reduced-motion authority.

📑 Contract Completeness Audit

  • Findings: N/A — this delta introduces no new JS/runtime/public API or global token surface. It corrects consumption and values behind already-existing component aliases; the design artifact plus the named dock/theme authorities fully specify that internal contract.

🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: The cycle-1 three-part token check—declared vocabulary, defining authority, computed consumer—became a focused census at the exact failure boundary. This is the right close: fix the defect once, then make its recurrence mechanically visible.

📊 Metrics Delta

Verdict weights still apply: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

  • [ARCH_ALIGNMENT]: 91 -> 100 — the correction removes both false authority references, preserves the component/domain/global layering, and leaves the implementation successor intact.
  • [CONTENT_COMPLETENESS]: 88 -> 100 — artifact wording, SCSS comments, PR body, source authorities, and computed behavior now tell the same scoped story.
  • [EXECUTION_QUALITY]: 84 -> 100 — exact-head source, compiled CSS, focused 37-test suite, theme build, syntax/diff checks, and hosted gates all clear the specific failure modes from cycle 1.
  • [PRODUCTIVITY]: 94 -> 100 — the one remaining contract action is resolved without widening the PR or creating another author cycle.
  • [IMPACT]: Unchanged at 82 from the prior review — this remains the binding felt-experience authority for the docking front door, while implementation stays in #14959.
  • [COMPLEXITY]: Unchanged at 38 from the prior review — five localized design/theme/test files; the complexity lies in cross-authority correctness, not runtime branching.
  • [EFFORT_PROFILE]: Unchanged at Quick Win from the prior review — high design leverage with a narrow, mechanically guarded correction.
