| Authored the decomposed BDD implementation plan for CR 2026-08-23-001 at _agent_docs/plans/2026-08-23-cr-001-ui-enhancements/ (10 files, ~1 170 lines): index.md (phase map, all not started, CR linked as source of truth, D-M sequencing constraint), context.md (decisions D-A…D-M pinned with spot-verified anchors, D-D confidence-metric formula + tuning contract, D-K clicks20.wav fixture contract, D-L scenario ID scheme, KB-14…KB-17, 13-item risk register, CR §4 limitations), behavior-specs.md (73 canonical Given-When-Then rows: WF-P1.1…9, TD-1.1…15, WF-V1.1…10, WF-I1.1…5, WF-I2.1…10, TD-U1.1…10, E2E-3.1…10, E2E-4.1…4, with a worked-example constants header and P0/P1/P2 ordering), and phase-1…phase-7 files (each self-contained: depends-on by ID, context-to-load, inlined owned scenario tables, concrete code changes, automated/manual success criteria, phase-close handoff audit). Phases 1–6 are test-first with the broken-page RED shape (risk R-11) stated per phase for new barrel names; Phase 4 defines _schedulePostLoadTasks in two-task shape from day one so Phase 6 fills in, never refactors, the tempo task. Spot-verified the planner memo's key file:line anchors against source and corrected the stale ones (see key_decisions). Integrity check passes both default (R-*/RD-*) and custom --ids invocations (63 distinct new IDs all resolve canonically); by-eye ownership pass confirms every scenario ID is inlined in exactly one phase file (other occurrences are dependency/audit references only). No code files were modified — plan directory only. | 1 |
| CR 2026-08-27-002 fix complete per the pinned contract (spec §3 F-1/F-2, §4 tests, §5 criteria 1–4). RED (unit): extended the Proxy-era fake canvas to record backing-store assignments (getter/setter over _width/_height → canvas.assignments) and made the injected devicePixelRatio provider mutable (env.setDpr), then added WF-V2.1…WF-V2.3 — WF-V2.1 failed 'no backing-store assignment: expected 6 to equal 4' and WF-V2.3 failed 'a render is queued despite the unchanged CSS snapshot: expected +0 to equal 1' (WF-V2.2 green by construction, post-paint extension of WF-V1.2). GREEN: resize() in createWaveformView.js now computes wPx/hPx and assigns the backing store only when it differs (F-1), invalidating the _rendered skip snapshot inside that branch so a cleared store is always followed by an un-skippable render (F-2); setTransform still applied on every resize (WF-V1.3 pin preserved). RED (E2E): the new wipe regression in waveform.spec.cjs was verified red against the pre-fix production file (temp stash) — the same-size dispatchEvent('resize') left the in-page pixel count at 0 and the waitForFunction timed out at exactly the wipe assertion, reproducing the Android field report in chromium. GREEN: full unit suite 222/222 (WaveformViewTest 16→19), full E2E 38/38 (37 pre-existing + 1 new). Refactor phase: nothing beyond the pinned shape was needed — the fix is the sketch verbatim; no god-factory, no new imports, dispose()/init()/storm-coalescing behavior unchanged (all existing WF-V1.x green). Out of scope honored: no phone-profile project, no learnings/KB-18 entries, no commits. | 1 |
| Committed the fully staged CR 2026-08-23-001 change set as cd0748f 'Metronomad: add waveform progress + tempo suggestion — 228 unit tests, 37 e2e tests, skill docs' (27 files, +3929/−116) on prototype/metronomad. Verified the staged set file-by-file against the seven build-tdd phase session summaries (Phases 1–7: Analysis pure modules channelData/waveformPeaks/tempoDetection, DI-pure createWaveformView, _schedulePostLoadTasks wiring + paint gate, canvas-as-offset-slider replacing #offsetScrubber, tempo suggestion integration + clicks20.wav fixture, AGENTS.md + building-web-apps skill docs) before committing — all staged content matched the as-built records; nothing unintended staged (.DS_Store and unrelated untracked files left alone; _agent_docs/ is gitignored per repo pattern). Commit message follows repo style (Metronomad: subject, per-phase body, Unit/E2E count line, Co-Authored-By) plus a Pi-Session trailer per work session (7 trailers, one per phase session ID from the timeline summaries) so analyzing-pi-usage can attribute the commit to each contributing session. | 1 |
| Complete: (1) v1 spec finalized with all 6 open product questions resolved by the user; (2) Howler.js researched empirically (docs + source + live headless-Chromium verification harness) — concluded Option B: Howler for context/masterGain/codecs/autoUnlock, raw Web Audio start(when, offset) for the sample-accurate click grid and song start; (3) full BDD implementation plan written via the plan-bdd workflow (world-review + planner subagent delegation, synthesized with skeptical corrections): 93 Given-When-Then scenarios across user/component/pure-function/E2E levels, 11 design decisions (D1-D11), 8 phases with automated+manual success criteria, module interfaces, known behaviors, and test strategy. | 1 |
| Expanded the UI-enhancements change request in place (original text preserved verbatim) after a capability assessment: Howler 2.2.3 provides NEITHER a waveform/peak API NOR metadata/BPM analysis, and the decoded buffer is not retrievable from a Howl (research §5 pitfall 5) — but Metronomad already decodes and owns the AudioBuffer itself (fileLoader.js → _buffer), so both features build on standard Web Audio AudioBuffer accessors with zero new dependencies and zero Howler involvement (its role per howlerSetup.js is unchanged). The expansion adds, per feature: data/pipeline design (peak extraction with 4096-bucket high-res cache + min/max pooling; pure-DSP tempo detection = mono mixdown → leading-silence trim → half-wave-rectified frame-energy onset envelope → autocorrelation over 30–250 BPM with a 70–180 prior + confidence threshold), rendering/interaction/a11y design (canvas + div overlays; playhead re-uses the existing progressPercent computed on the 10 Hz songPosition tick — no second RAF loop, honoring D9; canvas role=slider for the offset with full keyboard parity table, .progress-readout role=progressbar for progress), state/memory (non-reactive handles, generation guards), draft acceptance criteria, test/E2E hook plans (KB-6 convention), open questions, and out-of-scope/limitations. Then ran the world-review subagent (qwen-agentworld-35b-a3b) over the expansion: 17 findings (W-1…W-17) — all incorporated in place with W-number citations and a full disposition table in §6; the most consequential were: sampleRate is not a constant (44.1/48/96 kHz depending on browser/device — both pure modules take it as an explicit input), the dual slider+progressbar role split, pointercancel + try/catch pointer-capture + touch-action: pan-y, confidence-metric/'null when unsure' contract for BPM (wrong-but-confident is worse than no suggestion), and generation guards for file-replaced/unmount mid-flight async tasks. Two reviewer suggestions were explicitly rejected with reasoning (keeping the native range alongside the canvas; requestIdleCallback as v1 default). Token/duration figures measured from the session JSONL (main agent only; the world-review subagent's own usage is in a separate session). | 1 |
| Metronomad v1 (all 8 plan phases) committed on branch prototype/metronomad as a0e3498 (51 files: app code, 127 unit + 21 e2e tests, fixtures, site launch card, gitignore/AGENTS.md process updates, skill docs), followed by housekeeping commit a6ecfc0 moving the canonical building-web-apps skill from CollageMaker/.opencode/skills/ to repo-root skills/ with relative symlinks from both CollageMaker/.opencode/skills/ and Metronomad/.pi/skills/. Unrelated untracked files (MacNotes.txt, BlogPosts report data, 73MB TaxBracketVisualizer/References, empty test-results/) intentionally left untracked. | 1 |
| Phase 1 (Scaffold) complete. Red-Green-Refactor cycle: wrote the Playwright smoke suite first (4 tests: zero console errors, data-state=noFile hook, drop zone hero + live regions, all 9 controls present and disabled), confirmed RED (4/4 failed on the missing page), then implemented the minimal shell — index.html with the full final-form template (drop zone, file row, locked controls group, playback buttons, beat dots, progress bar, polite/alert live regions), Style.css (drop-zone hero, beat-dot base + reduced-motion hook, tokens from variables.css), and the four app factory stubs + barrel per the repo's createCollageApp pattern. GREEN on first full run after fixing one test-side assertion (see learnings); 4/4 green across two consecutive runs. Barrel re-export names verified live in-browser (no silent undefineds); the scaffold-only formatSeconds placeholder verified against all seven planned formatTime contract cases (T-12…T-17) so the Phase 2 swap is seamless. | 1 |
| Phase 1 complete: the new MyESModules/Storage/ concern exists, test-first, with all 24 SL-P1 rows green and every pre-existing row byte-for-byte green (315/315, 0 failures, 0 pendings). (1) Loaded exactly the phase file's 'Context to load' (phase-1 file, index.md Overview/Current-State hook-point+barrel-paragraphs/Phase Map, context.md SL-D1…D3/D14/D15/D16/D19/D20 + both Storage module interfaces, behavior-specs.md shared fixtures + §1, paramClamps.js for guard/JSDoc style, index.js barrel, TempoDetectionTest.html top-80 page shape, es-modules.md numeric-guard + barrel-link-failure rules). (2) Re-verified the baseline at phase start: 291/291 (the plan's 287 predates a post-ship fix that added 4 rows — the task's 291→315 figures are the live ones; the phase file's '311/311' success criterion is stale). (3) RED: wrote MyComponents/SavedLoopsTest.html FIRST with direct imports of the two not-yet-existing Storage modules plus the barrel spot-check import (STORAGE_KEY as barrelKey, createLocalStorageAdapter as barrelAdapter) — runner reported 'mocha.run() was never reached within the timeout — test page error or hung suite' with two 404 console errors (the module-link failure shape, not green-by-accident), all 291 pre-existing rows still green. (4) GREEN: MyESModules/Storage/savedLoops.js (pure — constants STORAGE_KEY/SCHEMA_VERSION/MAX_ENTRIES/DURATION_TOLERANCE_SEC, createEmptyState, encode, parse with SL-D15 field-strict + the single W-6 missing-end-key→null leniency, entryMatches with the SL-D14 strict triple + inclusive 0.1 s + 1e-9 tolerance, addEntry with SL-D2 dedupe-refresh/append/oldest-savedAt-eviction and earliest-index tie-break and never-mutates-input, removeEntry, fileIdentityOf per SL-D19, newId per SL-D3 with randomUUID + 2-line fallback; every numeric read leads with Number.isFinite; JSDoc on every export, paramClamps style) and MyESModules/Storage/localStorageAdapter.js (createLocalStorageAdapter({ key, storage }) — construction probe, live `available` property, quota-name mapping, never throws). (5) Barrel: the 14 pinned re-exports added to MyESModules/index.js; every re-exported name verified to exist in its source by grep (the silent-failure learning), and the in-page barrel spot-check row passes. (6) All success criteria verified: 315/315; pre-existing per-file counts identical to the 291 baseline (18/15/33/16/52/121/9/27); no pre-existing test file edited (git status shows only index.js modified + the new files); rg 'localStorage' savedLoops.js → zero hits (had to reword 4 JSDoc comment mentions — the string 'localStorageAdapter' contains the needle); rg 'window\.' savedLoops.js → zero hits. No commit made (build-quick-work's responsibility after review). | 1 |
| Phase 1 of CR 2026-08-23-001 complete, all success criteria met. RED observed first in the pinned R-11 shape (WaveformPeaksTest.html importing 7 names through the barrel → 'mocha.run() was never reached'; console-verified as a link error naming the missing export before writing any implementation), then GREEN: MyESModules/Analysis/channelData.js (channelArrays/mixDown/monoMixdown, D-B verbatim) + MyESModules/Analysis/waveformPeaks.js (extractPeaks/poolPeaks, D-C verbatim) + barrel block → WF-P1.1…WF-P1.9 all pass (9 tests; suite 167/167) and npx playwright test unchanged at 23/23 (no app surface touched). Refactor phase needed no structural change (modules are pure, ≤3 methods, no cross-layer imports; grep passes clean); two JSDoc contract pins added (bucket↔song-time alignment; no-mutation aliasing). Phase-close handoff audit run: Phase 2's mixDown import shape and Phase 3's WF-V1.1 pooling assumption both verified against as-built (floor-based pool partition is exact: start(b+1)===end(b), end(last)===sourceCount). One plan bug found by worked-example recompute and corrected in place: WF-P1.7's spike 'sample 40 000 000' is out of range for the 20 000 001-sample buffer → 'sample 4 000 000 (in range; a stride-4 multiple)' in behavior-specs.md and phase-1-peaks-pure.md; plan-integrity-check re-run passes (63 IDs). World-review triage: the one 'critical' (main-thread cost) refuted by a 59 ms benchmark of the true 30-min stereo @48 kHz worst case — settled W-6 disposition stands (stride = mitigation, chunking = documented fallback); two JSDoc pins added from legitimate findings; the rest rejected as conflicts with pinned contracts (D-B guard scope, WF-P1.9 reference identity, pinned 20 M-sample test size). Phase marked done in index.md phase map; project timeline updated (CR 001 section, trajectory row 167/23, current state); two new learnings written + one addendum to the 2026-08-22 esmodule learning. Work is UNCOMMITTED — committing is build-quick-work's responsibility. | 1 |
| Phase 1 of CR 2026-08-29-003 complete, all success criteria met. RED observed first in the pinned R-11 shape (TimingMathTest.html's direct import of clampEnd/MIN_SECTION_SEC → '[PAGE ERROR] does not provide an export named MIN_SECTION_SEC' — a link failure, not per-test failures, no phantom hunting), then GREEN: MyESModules/Utils/paramClamps.js gains clampEnd(value, offset, duration) + MIN_SECTION_SEC = 0.1 and clampOffset gains the optional maxOffset third argument (omitted/non-finite/negative → duration — bound = min(maxOffset, duration) then the existing quantize-then-reclamp), both verbatim from the plan's pinned code; barrel re-exports both new names. EN-C1.1…16 green (16 new rows; T-26…T-35 byte-for-byte untouched); full unit suite 248/248 (8 suites), npx playwright test 38/38 unchanged (no app-visible change — the app never calls the new names until Phases 2–3). Barrel positive-resolution verified in-page over the live server (a 3-line temp MyComponents page + Playwright console capture: 'CHECK function 0.1 2.9 1.5 0.1'; node cannot import the static-site ESM directly — no type:module). Refactor phase: no structural change — two pure functions + one constant in a single-concern module, no imports, no browser APIs; the shared 3-line quantize-then-reclamp pattern is the U-10 'one law' and is pinned verbatim by the plan. World-review: zero warnings/criticals; two Suggestion-level findings addressed — (1) JSDoc precondition pin on clampEnd (its tenths return contract assumes a COMMITTED, already-quantized offset; an unquantized offset like 1.23 pushes lo off-tenths and the final re-clamp-up returns 1.33 — contract note, not a behavior change, per the reviewer's own calibration rule, since EN-D2 is silent on the precondition); (2) identity-case assertion added to EN-C1.16 (explicit bound === duration: clampOffset(2.5, 3.0, 3.0) → 2.5). One plan bug found and corrected in place (second occurrence of the family in 5 days, first in a clamp table): EN-C1.15's original Given clampOffset(2.5, 3.0, 2.96) → 2.9 is arithmetically wrong — 2.5 is in-range and clamps to itself under the plan's own reference implementation; the row's stated intent ('T-35 law at the bound') requires the value at/above the bound. Corrected to 2.96 → 2.9 and 3.0 → 2.9 plus the in-range fixed point 2.5 → 2.5, in both behavior-specs.md and phase-1-clamps-pure.md with dated correction notes; plan-integrity-check re-run passes (65 IDs). Baseline re-verification (the plan's own instruction) surfaced a count discrepancy: the plan's 'Current State Analysis' says 228/228, but the measured baseline at HEAD (git stash of the 3 changed files, runner output) is 232/232 — the CR-001-era summaries undercounted by one (229 it( calls at cd0748f, not 228) and the plan's 228 predates CR 002's +3; 229+3=232 reconciles exactly. Timeline + phase map record the measured numbers. Phase-close handoff audit vs Phase 2: all 'Context to load' files exist; P-15…P-22 never reference clampEnd (pinned: 'the engine takes a plain length — it never calls clampEnd'); worked examples recompute (P-15: tP=0, countIn 2 @ 120 → songStart 1.5; P-19: 0.5+5 clamps to 1.5; P-22: min(5.0, 2.5)=2.5). Phase marked done in index.md phase map. NEW learning doc written (second-occurrence pattern): scenario-row Givens must reach the named boundary — see files_created. Work is UNCOMMITTED — committing is build-quick-work's responsibility at CR close. | 1 |
| Phase 1 of the 2026-08-22 v1-review-fix plan is complete and green: C-1 (commit-on-Enter/blur BPM + count-in), I-1 (file-acceptance choke point), I-2 (single-flight decode), I-3 (engine end-of-song offset guard + clampOffset quantize-then-reclamp), I-4 ("Preview stopped" on user stop), and I-9 (runner can no longer report green with 0 tests / failing tests / blocked CDN), plus add-ons N-16 (shared _restoreLastValid), N-20 (count-in clamp hint), N-22 (U-21 long-filename E2E), N-23 (re-clamp-on-shorter-file test). Unit suite 142/142 (baseline 127, +15, none deleted); E2E 23/23 (baseline 21, +2: E2E-R-C1.1, E2E-U-21). Every automated success criterion in the phase file is met; the phase is marked done in index.md and the handoff audit against Phase 2 was run. No files committed (build-quick-work's job). | 1 |
| Phase 2 (Pure Functions) complete. Red-Green-Refactor: wrote scripts/run-tests.cjs (CollageMaker runner adapted, BASE_DIR → Metronomad) + MyComponents/TimingMathTest.html with all 34 T-scenarios importing the not-yet-existing Utils modules, confirmed RED (3× module 404, 0 tests registered), then implemented the minimal pure functions — Utils/beatGrid.js (beatInterval/buildSchedule/beatPhaseFromGrid), Utils/timeFormat.js (formatTime/parseOffsetInput), Utils/paramClamps.js (clampBpm/clampCountIn/clampOffset + range constants) — and updated the barrel. GREEN: 34/34 pass, 0 failures. Refactor phase: swapped the Phase 1 formatSeconds placeholder in createMetronomadApp.js for the real formatTime import (behavior-neutral, placeholder had been contract-validated in Phase 1), verified all 19 barrel names resolve live in-browser (no silent undefineds), re-ran full unit suite (34/34) + Phase 1 smoke E2E (4/4) — no regressions. | 1 |
| Phase 2 complete. Pinned sequence followed (R-I5.1 → R-I6.1/R-I6.2 → R-I7.1 → R-I8.1 → docs), each step RED-verified before GREEN. Engine visual clock deleted (no startVisualClock/stopVisualClock/onFrame/_rafTick, and the now-unused raf/cancelRaf factory params — verified nothing else consumed _raf); P-12 retired with a pointer comment to B-01/B-02. Teardown ownership flipped: createBeatDots(vm, base, callbacks) captures vm once, stopAll touches only visualizer resources, beforeUnmount owns listener removal → stopAll() → engine.dispose() → fileLoader.release(). createBeatDots is now as DI-pure as the engine (base.raf/cancelRaf/matchMedia/isPageHidden with browser defaults) and BeatDotsTest.html contains zero window.*/document.* monkey-patching (all global save/restore boilerplate deleted; per-test makeEnv fakes instead). BEATS_PER_BAR = 4 exported from beatGrid.js; accent rule, DOT_COUNT, Vue data beatsPerBar, and the template v-for all bind to it. Docs: AGENTS.md bullets rewritten (visual-clock sole ownership, Howler autoSuspend/autoUnlock split, Memory beforeUnmount order), v1 context.md D9 ownership pin rewritten + stale 'clear error/toast timers' step struck, lifecycle JSDoc aligned, v1 behavior-specs P-12 struck with pointer, B-05 amended, T-08/T-10 now inputs corrected (101.75/102.499), E2E-2.3 9:99.9 → 9:59.9. Final state: unit 145/145 (baseline 142 − 1 for P-12 + 4 new rows R-I5.1/R-I6.2/B-06/R-I8.1; B-05 rev was a 1-for-1 replacement, R-I6.1 folded into the B-05 rev test, R-I7.1 adds no new rows), E2E 23/23 unchanged (E2E-1.8 green — the net for I-8). All phase grep passes return zero code hits. Handoff audit run against Phase 3 scope list; Phase 2 marked done in index.md. Not committed (orchestrator commits after review). NOTE: token/duration figures are estimates — the session JSONL was not available in this environment for exact extraction. | 1 |
| Phase 2 complete: the saved-loops feature is wired into the Vue app, test-first, with all 28 SL-U1 rows + the SL-D20 barrel spot-check green and every pre-existing row byte-for-byte green (343/343 unit, 0 failures, 0 pendings; E2E 49/49 — the plan's '48/48' gate predates a post-ship CR-002 resize row, re-based exactly as Phase 1 re-based 311→315). (1) Loaded exactly the phase file's 'Context to load' (phase-2 file, index.md Overview + sequencing constraints 1–4, context.md SL-D7/D8/D9/D10/D11/D12/D13/D16/D17/D18/D22/D23/D24 + RB-1/4/5/8, behavior-specs.md shared fixtures + §2, the three App source files, UiHandlersTest.html mock-VM pattern, the Phase 1 session summary). (2) RED: appended a new `describe('SL saved loops')` block (28 `it`s) to MyComponents/UiHandlersTest.html + 3 new imports (direct savedLoops/localStorageAdapter + barrel STORAGE_KEY-as-barrelKey spot-check per SL-D20) + the makeFakeStorage helper copied from SavedLoopsTest (Phase 1 consumption note: reuse, don't re-invent). Runner reported exactly 28 failing — all SL-U1 rows, all real assertions (announcement mismatches, matchedEntryIds undefined, vm.onSaveSetup not a function) — while all 121 pre-existing UiHandlers rows and the other 7 suites (194 rows) stayed green. (3) GREEN: createMetronomadData.js gains the five SL-D17 reactive fields (inline literals, not createEmptyState()); createMetronomadMethods.js gains the import line, the file-header non-reactive-handle docs (_loopStorage/_liveFileIdentity/_setupSavedHintTimer), the SL-D8 ok-branch hook (byte-for-copy between the end re-clamp block and the READY flip, before _schedulePostLoadTasks), _draftsClean (SL-D9 six clauses), applySavedSetup (SL-D7 byte-for-copy), setupSummary/savedDate (SL-D24), onSaveSetup (SL-D18 write-first + 3 s _setupSavedHintTimer), onLoadSetup (SL-D13/SL-D22 backstops → apply → restoreHint), onDeleteSetup (write-first; ok → assign, failure → savedLoopsAvailable false, both → _refocusSaveButton refocus). createMetronomadLifecycle.js: storage probe at the very top of mounted (before initHowler — SL-D16 byte-for-copy incl. the console.warn), teardown additions at the head of beforeUnmount (after visibilitychange removal, before the visualizer teardown), JSDoc updated for both hooks. (4) Success criteria: 343/343 (315 + 28); git diff on MyComponents/ = 457 insertions, 0 deletions (no pre-existing row touched, V-05 bare-{name} drops byte-for-byte); rg 'loaded — ' createMetronomadMethods.js → exactly the two new composed strings; hook position visually verified (end re-clamp → identity/matched → READY → errorMessage → 3-branch → _schedulePostLoadTasks); npx playwright test → 49 passed, 0 failed (no template yet — the app renders exactly as before). No commit made (build-quick-work's responsibility after review). | 1 |
| Phase 2 of CR 2026-08-23-001 complete, all success criteria met. RED observed first in the pinned R-11 shape (TempoDetectionTest.html importing detectTempo/TEMPO/CLICK through the barrel → 'mocha.run() was never reached' page error before any implementation), then GREEN: MyESModules/Analysis/tempoDetection.js (detectTempo + TEMPO; mixdown → leading-silence trim → half-wave-rectified onset envelope → energy-normalized autocorrelation over the imported BPM_MIN/BPM_MAX range with 70–180 prior, parabolic refinement, out-of-band-alias rule, best/non-aliased-runner confidence) + barrel exports → TD-1.1…TD-1.15 + pinned-constants test all pass (16 tests; suite 183/183) and npx playwright test unchanged at 23/23. One tuning-contract adjustment: MIN_ONSET_FRAMES 8 → 12 (75 %-overlap frame grid yields ≈2 onsets-above-floor per click; 6 clicks → 11, which pinned 8 would have let through TD-1.11 — every pinned outcome re-verified). Refactor phase: one guard fix (refinePeriod reading the corr[0] placeholder) + two JSDoc/const polishes; post-refactor robustness probes all sane (stereo, 96 kHz, onset-over-tone, fade-in, 30-min window clamp, degenerate inputs never throw). Success-criteria grep passes: zero sample-rate literals, no 30/250 range re-declaration (range comes from BPM_MIN/BPM_MAX imports). Measured worst case: 14.0 ms (60 s @ 48 kHz), 10.6 ms (30-min file, window clamps) — well under the 50 ms D-D budget. Phase-close handoff audit vs Phase 6: return shape { bpm: integer, confidence } | null matches applyTempoSuggestion's result && result.bpm gate exactly; TD-1.15 accent-mix (the clicks20.wav fixture shape) holds at 120 ± 1. World-review: ZERO action items — all five flagged deviations sanctioned; both discussion items were plan-doc errors, corrected in place (TD-1.3 row; D-D lag formula). Phase marked done in index.md; timeline updated (CR 001 section, trajectory row 183/23, current state); one new learning written. Work is UNCOMMITTED — committing is build-quick-work's responsibility. | 1 |
| Phase 2 of CR 2026-08-29-003 complete, all success criteria met. At session start, Phase 1 (clamps) was done per the phase map but UNCOMMITTED in the working tree — committed it first (cbb9e26) so Phase 2 is a clean per-phase commit (the user directed phase-by-phase implementation directly, so per-phase commits replace the plan-at-CR-close commit; the Phase 1 session summary's next_steps 'commit at CR close' note is superseded). TDD cycle per the pinned RED shape (ordinary per-test — no barrel change, no new exports, all modules link): wrote all 8 P-15…P-22 rows first in a new describe block reusing the existing fake context/clock/timers (zero real AudioContext; the existing recording stub's start(when, offset, duration) already captures arity — a 2-arg call leaves startedWith.duration === undefined, which is what P-16 pins), confirmed 8 real-assertion REDs (expected undefined to equal 1 / expected 3 to equal 1.5 / ok:true vs ok:false — no link errors, other suites green), then GREEN with the engine diff verbatim from the phase file: startSequence destructures optional length, P-13 validation gains (length != null && (!isFinite || <= 0 || offset + length > buffer.duration + 1e-6)) before touching anything, _seq gains length: length ?? null, the D5 start is conditional (3-arg bounded — the preview() precedent — vs byte-for-byte v1 2-arg unbounded), the frozen N-4 snapshot gains length, songPosition's playing-branch hi clamp is offset + length while bounded, and preview({buffer, offset, length}) validates length first then generalizes D2 to remaining = min(length, buffer.duration − offset). Untouched per the pin: stop, restart (bounded restart free), _finish/_teardown, D4 counter, scheduler, D10 watch, getBeatGrid, dispose, ENGINE_EVENTS. GREEN: 256/256 unit (PlaybackEngineTest 25 → 33; P-01…P-14/H-03 byte-for-byte unedited — the unbounded regression gate held with zero edits to pre-existing rows), 38/38 E2E (the app never passes length — section behavior unchanged). Scope criteria verified: every rg 'length' hit in playbackEngine.js is a CR-003 addition inside startSequence/preview/songPosition (+ the _seq shape comment); zero barrel diff. Refactor phase: nothing to extract — the pinned diff is already minimal and fits the engine's existing structure (SRP intact, DIP unchanged, no new exports). World-review (qwen-agentworld): 1 warning + 3 suggestions, NO code change on any — see key_decisions for the per-finding dispositions. Phase-close handoff audit vs Phase 3: all 'Context to load' files exist; Phase 3's inlined rows that touch the engine (EN-U1.17 _sequenceParams shape, EN-U1.18 preview shape) match as-built; EN-U1.20/21/22 file-swap clamp chains recomputed against as-built clampEnd (incl. the 0.55*10 = 5.5000…01 float case where the quantize floor drops to 0.5 and the re-clamp-up-to-lo restores 0.55 — the collapsed-range pin working as designed). Phase marked done in index.md (with measured counts + world-review dispositions); timeline updated (trajectory 256/38). Committed bf08f7e. Learnings: no new doc this phase — the one genuinely new insight (pinned-plan behavior that a reviewer will flag as a defect needs its unreachability argument at review time) is a process note absorbed into this summary and the phase-map status rather than a standalone doc; see learnings for why. | 1 |
| Phase 3 (File Loading) complete. RED: wrote MyComponents/FileLoaderTest.html with 14 scenarios (F-01…F-09, H-01, H-02 + release idempotence) importing the not-yet-existing Audio/File modules — confirmed RED (3× module 404, 0 tests registered). GREEN: implemented Audio/codecSupport.js (H-02), Audio/howlerSetup.js (H-01, Pitfall 1 autoSuspend=false + Pitfall 2 volume(1) lazy-ctx touch), File/fileLoader.js (F-01…F-09, all deps injected: codecs/context/maxDurationSec/onStateChange; single-live-URL invariant on every exit path), then wired Vue: real onDrop/onFileInputChange/onFileDropped (V-05 contract, U-13 drop-while-locked guard, U-16 error clearing, offset clamped to new duration), lifecycle mounted() = initHowler + createFileLoader (Phase 3 subset; engine/beatDots deferred to Phase 4/5), beforeUnmount = fileLoader.release(). REFLECT: 14/14 new + 34/34 Phase 2 unit tests green; all 22 barrel names resolve live in-browser; verified the real UI in headless chromium — upload real 3 s MP3 → Ready + '0:03.0' + 'sine3s.mp3 loaded' announcement; garbage file → friendly decode error with state preserved (D8); re-upload clears error (U-16); .txt → codec message; zero console errors; Phase 1 smoke E2E 4/4. REFACTOR: fixed extensionless-file codec message ('. files' → 'unrecognized type', test-pinned first); runner fix (see key_decisions). | 1 |
| Phase 3 complete — all 21 scoped nit items landed in two TDD batches, both suites green, world-review clean, review remediation (all 3 phases) closed. Scoping pass first: 21 per-item phase files + behavior-specs.md §7 scenario rows + index.md sub-table. Batch A (commit 4e915d5): N-1 scheduler interval cleared at the PLAYING flip (R-N1.1 fake-timer count: 2 timers pre-flip, 1 post-flip, 200 no-op ticks schedule nothing); N-4 startSequence returns a frozen schedule snapshot (R-N4.1 — writes throw TypeError in strict mode, engine's internal _seq untouched); N-5 tooLong message interpolates maxDurationSec (R-N5.1; default '30 minutes' string unchanged via F-06 re-pinned with a 1900 s buffer); N-6 _finish(event) extract (refactor-only — behavior pinned by P-04/P-06/P-07/R-I4.2); N-7 ENGINE_EVENTS export + app switch on constants + barrel re-export (R-N7.1). Batch B/D (commit d57bf21): N-8 targeted errorMessage clearing (Stop clears only the drop-lock message — R-N8.1b pins that an unrelated decode error SURVIVES a Stop; successful Play/Restart/Preview clear stale errors — R-N8.2/R-N8.3); N-9 --beat-interval set only on value change with cache reset in _clearDots (R-N9.1 — 5 frames = 1 setProperty; stop+restart re-applies the same value); N-10 progressbar static aria-label + :aria-valuetext=formattedPosition, progressAriaLabel computed deleted (B-04 rev — template pin via fetch+DOMParser asserting the literal ':aria-valuetext' attribute); N-12 'Count-in restarted' announcement (R-N12.1; keyboard E2E updated to the new string); N-13 onDragLeave relatedTarget child-guard (R-N13.1 — pointer-events:none rejected at scoping because it would disable the Browse button, a child of the zone); N-14 post-resume-await unmount guard (R-N14.1 — RED was a TypeError on null engine, GREEN is `if (!this._engine) return;` after the await); N-15 dead scrubber :tabindex dropped; N-19 hint+placeholder 'm:ss.t' (V-04 assertions updated); N-25 resume-timeout assertion uses the SCHEDULER constant; N-26 E2E-1.3 bound = grid-law flip time (1500 ms) not 450 ms (R-N26.1 — the review's literal 'actionT < playing.t' is impossible: a count-in stop never reaches playing, so no playing timeline entry exists); N-27 refocus disabled-branch pinned (R-N27.1). Batch C docs: KB-11 (background-tab throttle compresses count-in; skip-clicks fix deferred), KB-12 (AT coalescing accepted), KB-13 (background audio continues — intended; kept separate from KB-11 per scoping) in v1 context.md with KB-10's ID/position preserved; U-18 scoping note (unit-adequate; ctx.suspend() E2E variant dropped) in v1 behavior-specs. Final state: unit 158/158 (baseline 148 after batch A, 158 after batch B: +10 new rows, 2 V-04/B-04 in-place updates, 1 R-N25 in-place update), E2E 23/23. World-review (qwen-agentworld-35b): all 7 targeted concerns fine, no issues. String audit: N-8 adds zero strings; N-12's 'Count-in restarted' fits the spec §10 exemplary family. NOTE: token/duration figures are estimates. | 1 |
| Phase 3 of CR 2026-08-23-001 complete, all success criteria met. RED observed first in the pinned R-11 shape (WaveformViewTest.html importing createWaveformView through the barrel → 'mocha.run() was never reached' before any implementation — though the signal was a disjunction: the page ALSO shipped missing its trailing load→mocha.run() listener, which persisted the identical signal after the barrel fix; disambiguated with a one-page Playwright probe, see new learning). Then GREEN: MyESModules/App/createWaveformView.js (DI-pure createWaveformView(vm, base, callbacks) — pooled min/max columns one-per-CSS-column mirrored about center, RAF-coalesced with no-op dedupe, DPR backing store, optional pointer-scrub path with capture try/catch + pointercancel/blur/global-pointerup cleanup, idempotent dispose with GPU release) + barrel export → WF-V1.1…WF-V1.10 + 3 supporting rows all pass (15 tests; suite 198/198) and npx playwright test unchanged at 23/23. Refactor phase: single-concern factory, no SOLID action; one comment fix. Phase-close handoff audit vs Phase 4 caught ONE real gap: D-F pins init as 'DPR sizing + listeners' but the as-built init left the backing store 0×0 (Phase 4's wiring calls only init at mount; no window-resize event fires at mount) — fixed by having init perform the container-measured resize; documented as D-F as-built delta (3) in context.md. Measured worst-case render cost: 0.006 ms/call (poolPeaks(4096→640) + 640-column y-math, R-8 width bound, warmed Node/V8, canvas calls excluded — same order). Success-criteria grep pass: zero global patching in the test page; RAF only through base.raf (I-7 default). World-review: ZERO action items — all five briefed hypotheses verified against code + pinned constraints; the three as-built deltas (resize one-arg height default via getHeightCss; base.getWindow for the injectable listener map; init container-measured sizing) sanctioned and documented. Phase marked done in index.md; timeline updated (CR 001 section, trajectory row 198/23, current state); one new learning written (canvas Proxy ctx mocks: wrap every called method + record off the plain object; secondary: the broken-page RED signal disjunction). Work is UNCOMMITTED — committing is build-quick-work's responsibility. | 1 |
| Phase 3 of CR 2026-08-29-003 complete, all success criteria met. TDD per the pinned RED shape (ordinary per-test — app modules already link, new members are object properties/methods, no barrel change): wrote all 23 EN-U1 rows (new describe in UiHandlersTest.html — the mock VM picks up the new data fields + computeds automatically via createMetronomadData()/createMetronomadApp(), zero harness change; file-swap rows use loader results of 20 s / 0.8 s / 0.55 s / 0.9 s over a live 3.0 s file with constant-amplitude AudioBuffer-shaped buffers so the real post-load analysis tasks run safely) + all 8 EN-V1 rows (new describe in WaveformViewTest.html — a makeFakeHandle with add/removeEventListener + set/releasePointerCapture, a makeEndEnv wiring both offset and end callbacks, and a display-only env for the EN-V1.2 gate), confirmed 30 real-assertion REDs (22 'not a function' / wrong-state on EN-U1, 8 'initEndHandle is not a function' on EN-V1 — no link errors, every pre-existing row green), then GREEN with the pinned code essentially verbatim: 5 data fields beside the offset block; endPercent/endMarkerPercent computeds (both through the shared percentOfDuration law; null end → 0 guarded shape); _offsetMax() as the single bound expression applied at all five offset commit sites (onOffsetScrub, onWaveformScrubStart/Move, commitOffsetEntry, onWaveformKeydown End key); commitEndEntry with the EN-D6 ordering (empty FIRST → null with NO restore — the V-03 asymmetry; then parse via the reused parseOffsetInput; invalid → revert + the reused format hint; numeric clamp is clampEnd with the two-hint selection by parsed > value); the onEndScrub family (onEndScrub is the one shared end-scrub law, U-10; the drag handlers are draft-only and deliberately NEVER call _waveformView.setDraft — end drags do no canvas repaint); the onFileDropped ok-branch end re-clamp after the offset re-clamp (inexpressible section → null + 'Section end removed (song too short)'); the ENDED-branch 'Section ended' vs 'Song ended' composition (engine emits one ENDED either way — EN-D7); the conditional length key in _sequenceParams/onPreview (ABSENT when unbounded — EN-D15); and createWaveformView's second pointer path (initEndHandle — W-1 hygiene replicated verbatim in shape, independent _endDragPointerId, x→tenths reusing _tenthsAt/the canvas rect, the EXISTING window pointerup/blur nets fanned out to both drag states — zero new window listeners, dispose() extended to the handle's four listeners). GREEN first hit 3 test-side failures — all my own float-literal pins: 180/300·3 is 1.7999…98 in binary (the skill's dyadic-inputs rule, testing-unit.md:489, already documents this trap with the same x/cssWidth·duration example; the pinned Given '60 % → 1.8' is non-dyadic, so the resolution is keep the Given + tight closeTo(12), see the new 2026-08-30 learning doc). Final: 287/287 unit (256 baseline; V-01/U-08 deep-equals and the WF-V1.4 listener inventories byte-for-byte unedited — the R-5 gate), 38/38 E2E (no template change yet — the app renders exactly as before). Success-criteria greps pass: the new tokens hit only the five App files; the view diff's only new addEventListener calls are on the handle (constraint 4). Refactor phase: one stale-doc fix — the view module header still described a single-surface canvas owner with 'three' callbacks; updated to the two-static-surfaces / six-optional-callbacks contract. World-review (qwen-agentworld, briefed with the six pre-written pin/reachability arguments per the 2026-08-29 learning): ZERO action items — all briefed hypotheses confirmed as settled design. Phase-close handoff audit vs Phase 4 clean: the waveform--locked class (index.html:139), the overlay stack (:158-163), the waveformEndHandle id (lifecycle), and every binding in Phase 4's template snippet exist as-built; EN-U1 boundary rows green = the worked-example recompute. Plan integrity check OK (65 IDs). Phase marked done in index.md with measured counts. Committed c9f0202 (code only — _agent_docs/ is gitignored; docs/timeline/phase-map updates stay local, consistent with Phases 1-2). | 1 |
| Phase 4 (PlaybackEngine) complete. RED: wrote MyComponents/PlaybackEngineTest.html with 22 scenarios (P-01…P-14, songPosition, dispose, P-07 edge, H-03×4) importing the not-yet-existing Playback/playbackEngine.js + Audio/clickBuffers.js — confirmed RED (2× module 404, 0 tests registered). GREEN: implemented Audio/clickBuffers.js (D7: 60 ms sine bursts, 1568/1047 Hz, 5 ms linear attack + exponential decay to 1e-5) and Playback/playbackEngine.js (generation counter D4, immediate sample-accurate song start D5, hand-rolled 25 ms/100 ms lookahead scheduler D6, 250 ms context watch D10, preview D2, D9 beat grid + visual clock). REFLECT: 22/22 new + 70/70 full unit suite green; all 29 barrel names resolve live in-browser; index.html loads with zero page errors; P-03 mash + P-04 stale-onended atomicity gate pass. REFACTOR: removed dead scaffolding from songPosition, fixed JSDoc param names, de-duplicated 30/250/1/16 literals in favor of paramClamps constants (AGENTS.md no-duplication rule), and one more RED-GREEN cycle for a frozen-state edge case found in review (song onended arriving before the countingIn→playing tick — offset within ~25 ms of track end). | 1 |
| Phase 4 of CR 2026-08-23-001 complete, all success criteria met. RED 1 (unit): WF-I1.1…WF-I1.5 + 4 D-H computed rows added to UiHandlersTest.html first — 9 failing (missing _schedulePostLoadTasks/_loadGeneration/computeds, verified as assertion failures not swallowed errors), all other suites green. GREEN: D-E verbatim hook in onFileDropped's ok-branch (generation bump, _bpmTouchedThisFile reset, waveformReady placeholder reset, _schedulePostLoadTasks at the END) + 4 new methods (_schedulePostLoadTasks two-task shape from day one per D-M; _runPeakExtraction with the pinned setTimeout(0) yield, _analysisValid guards pre/post extractPeaks, setPeaks from the guarded write; _runTempoSuggestion guarded no-op; _analysisValid three clauses) + lifecycle (view built display-only in mounted, _disposed-first teardown inserted between stopAll and engine.dispose) + data fields (offsetDraft/waveformReady/tempoSuggestion) + 4 computeds (progressPercent/offsetMarkerPercent untouched, R-4). RED 2 (E2E): new waveform.spec.cjs E2E-3.1…3.4 + smoke CONTROLS→CONTROLS/PRESENCE_ONLY split — 5 failing (no canvas in DOM), then GREEN with the D-H template + CSS (placeholder track, role=img tabindex=-1 canvas, dim/offset/playhead DOM overlays, progressbar role moved to .progress-readout per W-10, .progress-fill deleted, first width breakpoint 48px ≤375px). Two in-place fixes surfaced by the suite: (a) E2E-3.1 deviates from the plan's prescribed 5 ms logger BY DESIGN — the ready→first-paint gap is one setTimeout(0) + ~1 ms extraction ≈ 1.5–4 ms, sub-poll-period, so a 5 ms poll cannot order the two one-shot transitions (P(miss the gap) ≈ gap/period ≈ 30–80 % flake); in-page MutationObservers record each transition at its exact performance.now() timestamp instead — new learning doc written; (b) the B-04 (rev) template pin in BeatDotsTest.html pinned the pre-CR .progress[role=progressbar] markup and failed on the W-10 role move — updated in place to assert the role on .progress-readout with :aria-valuetext=formattedDisplayPosition and NOT on .progress (the settled W-10 disposition supersedes the v1 pin; the N-10 static-label rule travels with it). Success-criteria grep pass: progress-fill zero in index.html/Style.css (a self-referencing comment in the CSS had to be reworded — the grep is literal); progressPercent zero template consumers (computed retained per R-4); zero requestAnimationFrame in createMetronomadMethods.js (D9). Phase-close handoff audit vs Phase 5: clean — canvas attr diff vs the Phase-5 slider is trivial, createWaveformView exposes the three callbacks + setDraft as built, offsetDraft/displayPosition/markerPercent present, onOffsetScrub still the single commit law (stale JSDoc is Phase 5's R-5), keyboard.spec + playback.spec + U-10 rows untouched and green. World-review: ZERO action items — all nine briefed hypotheses verified (unmount/in-flight write window closed by the synchronous write block between the double guard; single render path (_peaks non-reactive, waveformReady the only reactive flip); container sizing at mount safe + resize listener recovery; placeholder-window overlays intentional per W-17/O-2; observer ordering deterministic (separate Vue flushes); no new per-frame work vs the old block; pointer-events lock independent of the coexisting scrubber; no peaks leak (poolPeaks allocates fresh, dispose nulls); displayPosition never shows a draft in Phase 4 — no handler sets offsetDraft yet). Final: 207/207 unit, 27/27 E2E. Work is UNCOMMITTED — committing is build-quick-work's responsibility. | 1 |
| Phase 4 of CR 2026-08-29-003 complete, all success criteria met. No unit tests this phase (pinned: the unit batteries landed in Phase 3; the E2E rows are the verification, green at phase close). Template: the End control group in the EN-D17 slot (between Offset and Count-in) — #endInput v-model endText, :disabled=!isReady, commit on Enter/blur via onEndCommit, empty = null with the 'song end' placeholder pinning the meaning, endClamped/endHint hint — plus the two new waveform overlays: the post-end dim (.waveform-dim--end, right:0 + width:auto, purely static per KB-14/EN-D12) and the dashed end handle (#waveformEndHandle, EN-D11: repeating-linear-gradient dashed --color-accent — texture not a third hue; 2px core + 24px transparent hit zone via padding + background-clip:content-box + margin-left:-12px; touch-action:pan-y; cursor:ew-resize; U-12 lock via .waveform--locked .waveform-end-handle). Both overlays v-show='waveformReady && end !== null', never v-if (EN-D9). CSS appended after the .waveform-offset-marker block (no new group CSS — base .control-group rules suffice). New section.spec.cjs: E2E-5.1…5.10 — the in-page 5ms transition logger copied verbatim from playback.spec.cjs (standalone-program convention) with ONE added read field: the playhead's data-position-tenths, which the bound-clamp claim ('reaches 15, never exceeds') needs; robustness verified by construction — formatTime/data-position-tenths round half-up, so the VM writes 1.5 as soon as a RAF frame lands in songTime ≥ 1.45 (a 50ms window ≈ 3 frames at 60fps), no race with onended. clicks20.wav via a local constant (helpers.cjs untouched per the plan); marker positions read from the handle's inline style.left in-page (no new hooks, KB-6); E2E-5.4 mixes a real-mouse drag (commit) with a synthetic PointerEvent pointercancel (discard, E2E-3.7 convention); E2E-5.8 pins EN-D9/R-3 observably by tagging the handle DOM node (__cr003) before a file swap and asserting the SAME node after (a v-if recreation would lose the tag). Same-commit spec updates per R-1/EN-D17: keyboard.spec.cjs 8→9-element exact Tab order (endInput between offsetInput and countInInput) + the locked-skip allow-list gains endInput; smoke.spec.cjs CONTROLS gains #endInput. First full run: 45 passed / 3 failed. Diagnosed: (1) E2E-5.9 — my loadFile(page, fixture) helper, transcribed from the plan's pinned shape, assumes a MOUNTED app (the plan intends it for post-loadFixture use); the row starts from a fresh page, so page.setInputFiles hung 30s on 'waiting for locator(#fileInput)' — fixed with waitForAppMount(page) first. (2) E2E-5.10 — PLAN WORKED-EXAMPLE BUG: the row's 'second count-in flips at restart+1500 / second ready / two Section ended' is unreachable — the grid law (count-in 4 @ 120) puts the flip at restart+(4+1)·0.5 = +2500 (the same file's E2E-5.1 says exactly this), and a mid-section restart ABORTS the first section, so the whole run produces exactly ONE ready transition and ONE 'Section ended' (the aborted section never completes; the interrupted sequence announces nothing). Corrected in place in behavior-specs.md + the phase-4 file with an annotation (Phase 1's EN-C1.15 correction is the precedent), and the spec pins the reachable literal. (3) E2E-5.1 — transient: the first full-suite run failed it (the error tail was not retained — only the E2E-5.9/5.10 errors were captured), and it passed both the isolated re-run and the full re-run; recorded as transient, not root-caused. Final: 287/287 unit (regression gate — zero unit change), 48/48 E2E (38 baseline + 10 section rows; section.spec.cjs also green in a dedicated stability re-run). Success-criteria grep 'rg "v-if" index.html | grep -i end' hits exactly one line: the v-if="endClamped" hint — the plan's own pinned template snippet includes it (v-if is correct for the non-interactive hint; EN-D9's no-recreation pin targets the handle + dim, which are v-show and protected observably by E2E-5.8). Tab-order spec asserts the 9 elements. Plan integrity check OK (65 IDs). World-review (qwen-agentworld-35b-a3b, briefed with the plan dir + diff + the E2E-5.10 correction for explicit verification): ZERO findings, ZERO discussion items — the E2E-5.10 correction confirmed mathematically sound. Phase map updated in index.md; timeline + trajectory + session record updated. Committed f2b20a3 (code only — the repo gitignores **/_agent_docs/, so the plan-doc/timeline updates stay local; consistent with Phases 1–3). | 1 |
| Phase 4 of CR 2026-08-30-004 complete, all automated success criteria met. Docs-only phase — no TDD (user-waived; no tests to write). Suites re-verified green from fresh runs with the server on :8000: 343/343 unit (node scripts/run-tests.cjs) + 56/56 E2E (npx playwright test, 1.7 min). Integrity check green: 83 distinct IDs, 4 phase files. Storage-key grep gate passes: 'metronomad.savedLoops.v1' exists exactly once as a constant (MyESModules/Storage/savedLoops.js:14) plus two test references (SavedLoopsTest.html:81, savedLoops.spec.cjs:33). AGENTS.md brought to as-built: (1) Architecture gains the Saved-loops bullet — T1 identity-only matching (never a path/handle/bytes), the pure Storage/ module + DI adapter (built at the top of mounted, before audio init), the ok-branch auto-apply synchronous BEFORE _schedulePostLoadTasks (RB-1 — do not move post-hoc), the W-4 single-writer apply law (bpm→countIn→offset→end, offset bounded by duration only, in-range restores clear stale hints), the W-1 six-clause dirty-draft guard, write-first Save/Delete (quota → banner + VM unchanged; delete failure → silent hide — RB-4), one composed live-region write per load (W-3 — Save/Load/Delete announce nothing), silent degradation (RB-8); (2) Directory gains Storage/, SavedLoopsTest.html (SL-P1.1…24), the UiHandlersTest SL-U1.1…28 note, savedLoops.spec.cjs; (3) Conventions extends the string inventory to the SL-D6 12-row list (zero-match '${fileName} loaded' marked reused-verbatim) + the touched-flag note (restore = user touch — CR-001 §2.5 table +1 row); (4) Memory bullet gains the saved-loops teardown slot (clearTimeout(_setupSavedHintTimer), _loopStorage/_liveFileIdentity null — adapter owns no listeners) + the exactly-one-record-list invariant (100-cap, oldest-savedAt-first, tie → earliest index — SL-D2); (5) new 'Documented limitations (CR 004)' section with the phase-pinned five (RB-3 copies don't match, RB-2/W-5 no live sync, RB-5 committed-models-only Save, RB-6 0.1 s backstop, RB-8 private mode); (6) Project Docs lines gain KB-19 + the CR 004 plan. v1 context.md gains KB-19 verbatim (schema incl. end: number|null present from day one; strict triple + 0.1 s backstop and their deliberate failure modes; structural tempo-suppression ordering RB-1 + tripwires; degradation matrix; no storage-event listener; no migration). Spot-check of every new doc claim against source (all 12 SL-D6 strings verbatim, hook position, six clauses, eviction law, write-first both handlers, beforeUnmount order, adapter construction site, refocus): zero plan-vs-code divergence. World-review (qwen-agentworld-35b-a3b, briefed with plan dir + changed docs + as-built paths): 2 suggestions — (1) ACTIONED: 'fourth row' wording was wrong — the CR-001 §2.5 flag table already has four set-true rows (input-event is row 4 in the code comments), so the restore is the +1/fifth row; corrected in AGENTS.md to '+1 row'; the phase file's own 'gains its fourth row' prose carries the same slip — record-only, as-built code comment wins; (2) DISCUSSION ITEM (not actioned): reviewer wanted RB-4/RB-7 added to the limitations section — the phase file pins exactly five items (a)–(e) and both behaviors are already documented in the Architecture bullet (write-first clause covers RB-4; dirty-draft-degrade clause covers RB-7), so it is a section-placement preference conflicting with pinned phase scope. Phase map in index.md shows 4/4 done with re-verified counts. The 10-item manual acceptance checklist awaits user sign-off. Committed 60acaaf (AGENTS.md only — the docs phase's only tracked artifact; _agent_docs/ stays local per gitignore). | 1 |
| Phase 5 (UI Integration, P0 acceptance gate) complete. RED-GREEN-REFACTOR in 5 batches over MyComponents/UiHandlersTest.html (mock-VM pattern: data + factory methods spread first, computeds from createMetronomadApp attached as live getters, $nextTick/$refs faked): V-01/V-05 (play toggle + _buffer storage) → V-02/V-03 (restart + BPM/count-in inputs/steppers) → V-04/U-08 (offset commit/scrub + preview) → V-07/V-06 (engine state → announcement mapping + computed characterization) → U-19 (suspended-context resume with 750 ms timeout). Final: 39/39 new + 109/109 full unit suite green; smoke E2E 4/4. REFACTOR: deduped previewEnded into _returnToReady, extracted _sequenceParams/_parseParamInput/_resumeWithTimeout, removed dead _masterGain handle, lifecycle now wires renderClickBuffers → createPlaybackEngine (onStateChange/onInterrupted → methods) with engine.dispose() first in beforeUnmount. Template finalized: ref=playStopBtn for focus return, :value+@input raw-value handlers for BPM/count-in/scrubber. LIVE PAGE VERIFICATION (throwaway Playwright script driving the real page with real audio) found and fixed a P0 the unit suite could not see: playStopBtn was :disabled="!isReady" — disabled while playing, so Stop was unpressable; now :disabled="!isReady && !isParamLocked". Post-fix live pass: full lifecycle (load → count-in → playing @1541-1556 ms of ~1500 → ended @4541 ms of ~4500 → stop w/ focus return → preview clamped 2048 ms → restart → U-13 drop rejection) with zero console/page errors. | 1 |
| Phase 5 (docs + acceptance — no TDD cycle per the phase file) complete for all automated criteria. (1) Loaded exactly the phase file's 'Context to load' (phase-5 file, index.md Desired End State + Overview, plan context.md EN-D9/EN-D13/EN-D18 + Known Behavior + References, project AGENTS.md, v1 context.md Known Behaviors, timeline for orientation), then spot-read the as-built source before writing any bullet: playbackEngine.js (startSequence/preview optional length, conditional 3-arg start at :267, _seq.length snapshot, songPosition bound), createWaveformView.js (initEndHandle second pointer path, four handle listeners, shared window pointerup/blur nets, zero new window listeners, dispose removes all), index.html (End control group between Offset and Count-in, #waveformEndHandle aria-hidden v-show, post-end dim v-show, placeholder 'song end'), all six EN-D18 strings in createMetronomadMethods.js, and the exact test row IDs by grep (EN-C1.1…16, P-15…P-22, EN-V1.1…8, EN-U1.1…23, E2E-5.1…10). As-built matches the plan — zero divergence, no plan correction needed. (2) Updated Metronomad/AGENTS.md: intro line gains the optional end point; Architecture 'Raw Web Audio' bullet gains the bounded-playback note (conditional 3-arg D5 start, termination rides the existing generation-guarded onended → ENDED path, absent length key when unbounded); the CR-001 waveform sentence gains the pointer-only end-handle note (W-1 hygiene, second pointer path, shared window safety nets, #endInput keyboard/SR path, canvas stays the single offset slider — W-10/KB-18); Directory gains section.spec.cjs and the four suite coverage notes; Testing clicks20.wav bullet gains 'file-swap E2E fixture (E2E-5.8/5.9)' keeping the R-9 never-assert-its-duration rule; Conventions gains the six EN-D18 strings (with 'Enter the time as m:ss.t' noted as reused, not new); Project Docs gains the CR-003 plan line and KB-1…KB-18. (3) Appended KB-18 verbatim after KB-17 in the v1 plan context.md with the file's established italic addendum line and curly-quote formatting to match KB-14…KB-17. (4) Gates all green: 287/287 unit (0 failures, 0 pendings), 48/48 E2E (chromium), plan-integrity-check OK (65 distinct IDs across behavior-specs.md/context.md/index.md), grep sanity: KB-18 present in v1 context.md and all six EN-D18 strings present in app source and AGENTS.md. Manual acceptance checklist (phase file §4 — 10 real-audio items: section-stop crispness, unbounded regression, three-ways-in agreement, offset bound, preview, VoiceOver/NVDA pass, file swap, mobile drag, reduced motion, restart) awaits user sign-off; it cannot be automated (audibility, SR, touch). | 1 |
| Phase 5 of CR 2026-08-23-001 complete, all success criteria met. RED 1 (unit): WF-I2.1…WF-I2.10 added to UiHandlersTest.html first — 10 failing (TypeError: vm.onWaveformScrubStart is not a function) — GREEN with the four handlers (onWaveformScrubStart/Move/End + onWaveformKeydown) in createMetronomadMethods.js, all commits funneled through onOffsetScrub (one quantization law, T-35; JSDoc re-pointed per R-5). RED 2 (E2E): E2E-3.5…E2E-3.10 added to waveform.spec.cjs — 6 failing against the display-only canvas — GREEN with the D-H template diff (canvas = ARIA slider: role/tabindex/aria-value*/aria-disabled/keydown), the lifecycle callback wiring (call-time lookup arrows), and the #offsetScrubber deletion with every E2E reference re-pointed in the same change set (R-2: keyboard.spec 3 sites incl. the re-pinned canonical Tab order, playback.spec E2E-1.3/E2E-1.6 canvas-lock assertions, smoke.spec CONTROLS). Final state: 217/217 unit, 33/33 E2E (the plan's predicted 27+6), rg 'offsetScrubber' over index.html test/ MyComponents/ MyESModules/ → zero hits, no Math.round(×10) quantization outside paramClamps.js. World-review: zero action items — all 8 briefed hypotheses verified; the single discussion item (tab-order placement vs plan prose) is an intentional DOM-order deviation, documented. Phase-close handoff audit vs Phase 6 clean (BPM group anchors + commitBpmEntry/onBpmStep/_restoreLastValid intact; _runTempoSuggestion no-op and two-task hook untouched per D-M). Phase 1–5 work remains uncommitted (user manages commits; build-quick-work's responsibility per context.md). | 1 |
| Phase 6 (Beat Dots, Progress, Clock Hygiene, P1) automated criteria complete. RED-GREEN-REFACTOR in 6 small batches: B-01 dot rendering (RAF callback-collector, 4 tests incl. lead-in + grid-null loop self-termination) → B-02 visibilitychange pause/snap/resume (2 tests) → B-03 reduced-motion static highlight + live media change + --beat-interval tempo sync (4 tests) → B-04 progress computeds characterization (2 tests, green immediately — Phase 5 code) → B-05 stopAll teardown (1 test: RAF cancel + engine.dispose watch-interval spy + matchMedia listener removal + idempotency) → Phase-6 wiring in UiHandlersTest (4 tests: countingIn starts the clock exactly once, playing flip does not restart, all three terminal states stop, onVisibilityChange delegates, no-_beatDots safety). Final: BeatDots 14/14, full unit suite 127/127 (5 files), E2E smoke 4/4, live page mounts with zero console errors and beatDot-0..3 ids present. REFACTOR: extracted _cancelLoop() (single RAF-teardown point), _render() now returns the grid so _tick/_renderNow stop double-calling engine.getBeatGrid(), single _dotEls() lookup per frame; the refactor initially broke B-02 (_cancelLoop reset _hiddenPaused that the hidden path had just set) — caught by the suite, fixed by keeping the helper side-effect-free. Production: createBeatDots.js (RAF visualizer, D9 pure phase per frame, imperative dot classes, tenth-second-throttled songPosition), methods (_startBeatDots/_stopBeatDots/onVisibilityChange + onEngineStateChange hooks), lifecycle (createBeatDots + document visibilitychange listener in mounted; stopAll first in beforeUnmount), template (dot ids, imperative --active ownership documented), Style.css (pulse on --active.--pulse at --beat-interval, --static variant, media-query safety net), barrel export. Manual gate remains: U-17 (tab switch snap), U-22 (reduced motion), dot/click lockstep at 120 & 250 BPM — phase map left 'in progress' until the user verifies. | 1 |
| Phase 6 of CR 2026-08-23-001 complete, all automated success criteria met. Fixture first (D-K ground truth): scripts/make-clicks20-wav.cjs (dependency-free, clickBuffers.js envelope math) → test/fixtures/clicks20.wav, 1 764 044 bytes, byte-identical regeneration verified (same md5 across runs), sanity pass decodes the ENCODED bytes and checks all 40 onsets at 0.5 s spacing. RED 1 (unit): TD-U1.1…TD-U1.10 + the V-07 announcement-inventory row ("Detected tempo N BPM" for two N values) added to UiHandlersTest.html — 11 failing (TypeError: vm.applyTempoSuggestion is not a function / vm.onBpmTextInput is not a function; flag assertions undefined) — GREEN with D-I verbatim in createMetronomadMethods.js: _runTempoSuggestion body (setTimeout(0) yield → _analysisValid → channelArrays → detectTempo → re-check → applyTempoSuggestion), the four-clause gate read at write time (R-10), flag set-true at the TOP of commitBpmEntry/onBpmStep + new no-op-except-flag onBpmTextInput (never in _restoreLastValid, R-12), barrel import of channelArrays/detectTempo (R-11). RED 2 (E2E): test/e2e/tempo.spec.cjs E2E-4.1…4.4 — 3 failing (no hint element) — GREEN with the pinned Detected ~{{ tempoSuggestion }} BPM and @input="onBpmTextInput" on #bpmInput. Final state: 228/228 unit (217+11), 37/37 E2E (33+4). Grep passes clean: _schedulePostLoadTasks → one definition still calling BOTH tasks (D-M, hook untouched); rg '44100|48000|1047|1568' under MyESModules/App/ → zero. Phase-close handoff audit vs Phase 7: the two owned strings are verbatim in code; KB-14 (reduced-motion playhead stays — CSS block only touches beat-dot animations) and KB-17 (raw-float :aria-valuemax="duration") spot-checked against as-built. Phase 1–6 work remains uncommitted (build-quick-work's responsibility per context.md). | 1 |
| Phase 7 (E2E Suite, P0/P1) automated criteria complete: all 12 E2E scenarios pass in 2 consecutive full-suite runs (16/16 incl. the 4 Phase-1 smoke tests), timing tolerances stable, unit suite 0 failures across 5 files (regression check). RED-GREEN-REFACTOR in 4 small batches: (1) E2E-1.1/1.2 — fixture extraction + timing methodology overhaul after node-side polling proved unreliable; (2) E2E-1.3/1.4/1.5 stop/restart with in-page scheduled actions; (3) E2E-2.1/2.3 errors P0 (decode failure, clamps); (4) E2E-1.6/1.7/1.8/2.2/2.4 P1. REFACTOR: extracted test/e2e/helpers.cjs (shared mount/load/appState), removed dead node-scope parser. NO production code changes were needed — the KB-6 data-state/data-beat hooks, autoplay-flag config, and no-webServer config all pre-existed from Phases 1/5/6; the phase deliverable is the suite + fixtures. PLAN CORRECTION FLAGGED: E2E-2.3's '9:99.9' is malformed per the pinned parser (T-22) — test uses '9:59.9' instead (see key_decisions). | 1 |
| Phase 7 (docs + acceptance — no TDD per the phase file) complete for all automated criteria. (1) Loaded exactly the phase file's 'Context to load' (index.md overview/end-state/scope, CR context.md KB-14…KB-17 + D-K + cross-cutting constraints, as-built AGENTS.md, v1 KB list, timeline, CR §1.8/§2.6), then diffed the as-built code against the plan: barrel Analysis exports, lifecycle teardown order, methods (hook, guards, prefill gate, touched-flag sites), index.html template (slider canvas, readout progressbar, hint, KB-6 hooks) — all match; no plan correction needed. (2) Updated Metronomad/AGENTS.md (Architecture: Analysis pure-signal modules, createWaveformView DI-purity + slider replacement, BPM-suggestion contract, playhead rides the 10 Hz songPosition throttle; Directory tree incl. Analysis/, three new test suites, clicks20.wav + make-clicks20-wav.cjs, waveform/tempo specs; Testing: no-real-AudioContext convention for tempo/view suites + clicks20.wav fixture rule + never-assert-its-duration; Conventions: KB-6 hooks extended, the two owned strings, _analysisValid guard discipline, extended beforeUnmount order). (3) Appended KB-14…KB-17 verbatim (with decision date + CR refs) after KB-13 in the v1 plan context.md. (4) Gates: 228/228 unit + 37/37 E2E green; plan-integrity-check OK (63 distinct IDs); rg 'offsetScrubber' → zero hits across index.html test/ MyComponents/ MyESModules/ AGENTS.md; KB-1[4-7] present. (5) Final whole-change-set world-review (subagent): zero action items — every Phase-7 doc claim verified line-by-line against source; cross-cutting risks (peaks GC, canvas backing store, task race, offsetDraft lifecycle, reduced motion, narrow viewport, iOS pointercancel) verified safe; UX-6 double-announcement remains the lone discussion item, already routed to the manual SR checklist. (6) Timeline milestone + trajectory row + phase map updated. Manual acceptance checklist (dual-SR incl. UX-6, real-song tempo accuracy, playback regression by ear, low-end mobile, memory cycles) awaits user sign-off; the commit (build-quick-work) is next. | 1 |
| Phase 8 automated work complete plus two post-acceptance TDD rounds. (A) Two RED-GREEN cycles: site-card verification (grep card-id/title/href + target URL 200) — GREEN after adding #metronomadCard to the Music Apps category-grid of the root index.html; AGENTS.md content-contract check (13 tokens) — GREEN after writing Metronomad/AGENTS.md (architecture incl. Howler scope + no-Tone.js D6 + app-level visual-clock ownership per the Phase 6 correction, directory tree, Running, Testing incl. in-page timeline-logger convention, conventions, _agent_docs pointers, Co-Authored-By). Automated gate: 127/127 unit + 16/16 E2E. Final quality gate: world-review over the P1 test files — all groups clean, zero Critical/Warning. (B) User asked for an automated keyboard pass: RED-GREEN on test/e2e/keyboard.spec.cjs (3 tests: exact ready-state Tab order; locked parameter controls unfocusable while counting in + focus-return to Play/Stop; keyboard-only full flow with live-region announcements). The RED run caught a REAL BUG: committing/scrubbing the offset in the ready state updated `offset` but not the `songPosition` data property, leaving the progress readout/aria-label stale — GREEN: `offset` watch in createMetronomadApp.js enforcing the ready-state invariant. (C) User approved two more automation items: test/e2e/reducedMotion.spec.cjs (U-22: reducedMotion:'reduce' context — active dot carries beat-dot--static, never --pulse, and the static treatment follows the dot as beats advance) and test/e2e/visibility.spec.cjs (U-17: stubbed document.hidden + real visibilitychange — dots FROZEN across the hidden window (app cancels its own RAF loop), snap on return equals the grid-law beat anchored on the in-page t0, loop resumes). Final: 127/127 unit + 21/21 E2E (16 + 3 keyboard + 1 reduced-motion + 1 visibility), verified stable (2 consecutive full-suite runs + 5× repeat of the visibility spec). Phase map in-progress pending user; user has since confirmed the 13-item manual checklist passes and asked to wrap Phase 8 up for commit. | 1 |
