Plan 01-09 Amendment 3 (2026-05-19) — atomic documentation pass for
the save-does-not-stop-recording charter reversal.
Changes:
- .planning/phases/01-stabilize-video-pipeline/01-09-PLAN.md:
Amendment 3 block added above <success_criteria> (mirrors
Amendment 2 placement). Describes the reversed charter,
references the new debug record, points at the inverted
test file + harness A14.
- .planning/phases/01-stabilize-video-pipeline/01-13-SUMMARY.md:
"Subsequent Reversal (2026-05-19)" footer added. Notes that
npm run test:uat still 15/15 GREEN under the inverted A14
contract; vitest baseline preserved at 98 GREEN.
- .planning/STATE.md:
Plan 01-13 closure block extended with CHARTER REVERSAL bullet
citing the 4 commit SHAs (6ac23fd RED, 7645765 GREEN,
1baaf45 A14 invert, this commit docs).
- .planning/debug/resolved/01-09-save-stops-recording.md:
SUPERSEDED 2026-05-19 footer appended (audit trail; original
fix was technically correct against its charter, reversal is
UX iteration not technical defect).
- .planning/debug/resolved/01-09-save-does-not-stop-recording.md:
NEW debug record landed directly in resolved/ (no checkpoint
cycle — orchestrator-diagnosed reversal). Documents symptom,
charter clarification cycle, fix shape, RED→GREEN evidence
with commit SHAs + vitest/harness output, anti-regression
coverage at unit + E2E layers.

Plan 01-13 Task 9 operator UAT closure. Operator 2026-05-19 empirical
session: SAVE click downloaded zip but recording stayed live (badge=REC,
sharing banner persisted, subsequent toolbar press re-opened SAVE-only
popup). Operator pressed 4×, got 2 zips + confusion.
Root cause: src/background/index.ts saveArchive() returns success after
chrome.downloads.download without signaling offscreen to stop or
transitioning the SW state machine — SPEC `Тз расширение фаза1.md`
"one click MUST produce a self-contained archive" was over-extended to
"always-on" framing by the implementation.
Fix contract (RED today; GREEN after src/background/index.ts patch):
A: setBadgeText({text:''}) called post-save (setIdleMode side effect)
B: setPopup({popup:''}) called post-save (re-enables chrome.action.onClicked
restart path per MV3 contract)
C: chrome.runtime.sendMessage({type:'STOP_RECORDING'}) dispatched
(offscreen recorder.ts:848 STOP_RECORDING case already wired —
no offscreen-side change needed)
D: NO mokosh-recovery-* notification fires (deliberate stop ≠ error;
mirrors Bug B `user-stopped-sharing` suppression branch from
.planning/debug/resolved/01-09-recovery-flow.md)
Tests A/B/C RED (assertion errors `expected 0 >= 1`); Test D GREEN today
as the regression guard against fix over-rotating to setErrorMode.
Test architecture mirrors tests/background/request-id-protocol.test.ts:
synthetic BUFFER response delivered via port.onMessage listeners to drive
saveArchive's request-id'd buffer fetch to completion. Empty-segments
BUFFER causes createArchive → EmptyVideoBufferError → catch branch; the
fix's STOP+IDLE dispatch MUST happen on both success and empty-buffer
paths (operator UI contract: SAVE click = stop, success or empty alike).

Untracked file present at session spawn (per orchestrator pre-flight
intelligence). The Bug B debug investigation that produced commit
b9eeeeb (the conditional-routing fix in src/background/index.ts
RECORDING_ERROR handler that Plan 01-11 assertion 6 verifies) was
recorded under .planning/debug/resolved/01-09-recovery-flow.md but
never committed. Importing it now so the debug provenance is
preserved alongside Plan 01-11's harness coverage of the bug class.

The 01-08 fix took TWO iterations, not one. Iteration 1
(commits 52c7636 + 74400ae, archived in cc6e81a) resolved
the SW INIT crash via resolve.alias for ebml + chrome.* mock
for the Tier-1 Layer 1 gate. That landing masked a SECOND
defect — ts-ebml's EBMLDecoder constructor crashes with
`ReferenceError: Buffer is not defined` because MV3 SW has
no Buffer global. The runtime path is unreachable at module
init (EBMLDecoder is only constructed when remuxSegments
runs, which only fires from the SAVE_ARCHIVE handler), so
Layer 1 of the gate could not catch it.
Iteration 2 (commits dd7bf00 + 761dfc0) closed that gap by
extending the Tier-1 gate to Layer 2 (source-imports
webm-remux.ts, invokes remuxSegments — caught the Buffer
bug empirically) and applying B+ — vite-plugin-node-polyfills
with narrow Buffer-only config — to provide Buffer at SW
runtime via bundler-level import rewrite.
Updates to the debug archive:
- frontmatter `updated:` bumped to 12:25Z
- two new Evidence entries (12:15Z Layer 2 RED, 12:20Z B+
GREEN) document the iteration-2 empirical path
- one new Eliminated entry: "C-config alone is sufficient" —
FALSIFIED by Layer 2 (the resolve.alias fix from iteration
1 is necessary but not sufficient; ts-ebml's runtime Buffer
use is an orthogonal concern that requires the polyfill)
- Resolution.root_cause rewritten to describe BOTH defects
(bundler-config + runtime-Buffer) and explain why they
surfaced sequentially
- Resolution.fix rewritten with iteration-1 / iteration-2
structure, citing all 4 commits across both iterations
- Resolution.verification rewritten with explicit Layer 1
vs Layer 2 verification claims and the full vitest count
(62 passing, 2 failing — pre-existing fixture-dependent
webm-playback duration tests, unchanged)
- Resolution.files_changed lists all 4 commits across both
iterations + this archive update
The session was correctly resolved-and-archived after
iteration 1 with the information then available; iteration
2 is an additive correction once the extended gate surfaced
the second defect. Per the project's
feedback-pre-checkpoint-bundle-gates memory, the extended
Tier-1 gate is now the canonical bundle-loadability check
any future plan executor with SW surfaces must run before
operator-empirical checkpoints.

Adds tests/background/sw-bundle-import.test.ts that loads the built SW
chunk under SW-simulated globals (Buffer/process/window/document stripped)
via a spawned Node child process. Pins the orchestrator-side gap that
caused Plan 01-08's SW init crash: the prior deps test only checked
SOURCE packages under default Node globals, never the bundled output, so
Vite/Rollup's CJS-interop bug (tree-shaking the `ebml` package while
leaving a dangling `{tools:f}=Pc` destructure against an empty Pc) went
undetected until operator empirical smoke.
RED against HEAD aabbd0c — failure surfaces the exact production error
("Cannot read properties of undefined (reading 'readVint')"), proving
the test is a true regression gate, not a tautology.
Also rewrites .planning/debug/01-08-sw-incompatibility.md to reflect the
actual root cause (Vite/Rollup CJS interop) rather than the orchestrator's
initial falsified hypothesis (new Function + Buffer globals — disproven
by Node simulation showing the throw fires at module-init line 12:33809
before any CSP-eval or Buffer-ref code path executes).
Full vitest: 60 passing + 3 RED (this gate + the 2 pre-existing Task 5
fixture-dependent duration tests). No regressions.
Per feedback-pre-checkpoint-bundle-gates.md (auto-loaded memory): any
future plan executor whose work surfaces a SW must run this test before
any operator-empirical checkpoint.

REQ-video-ring-buffer flipped from [x] back to [ ]. ROADMAP.md Phase 1
row reverted from [x] Closed 2026-05-15 to [ ] reopened 2026-05-16.
STATE.md status flipped phase_complete → phase_reopened with full
historical narrative preserved.
Root cause (confirmed at byte level by gsd-debugger 2026-05-16):
D-13's concat-of-self-contained-WebM-segments architecture produces a
3-EBML-header WebM that standards-compliant Matroska parsers
(mpv, ffmpeg, Chrome HTMLMediaElement) play only as the first segment
(~9.94 s) and silently drop the remaining 2 segments. Confirmed via
operator mpv drag-drop test of BOTH the canonical 2026-05-15 closure
fixture and the 2026-05-16 UAT-produced fixture — both exhibit the
same broken playback.
The 2026-05-15 "operator-confirmed clean Chrome playback" assessment
was insufficient: it verified the file plays without freezing but did
not measure total duration. Phase 1's primary deliverable
(REQ-video-ring-buffer / SPEC §10 #7) is therefore NOT satisfied.
Fix path chosen by user: ts-ebml (parse) + webm-muxer (write) to
replace mergeVideoSegments file-concat with real single-EBML remux.
Will land as Plan 01-08 via fresh /gsd-plan-phase ceremony.
RED test landed in tests/offscreen/webm-playback.test.ts (2 new
assertions on container-format-duration + ffmpeg-full-decode-duration).
2 failures, 53 baseline tests still GREEN.
Option C port-lifecycle refactor (debug session
empty-archive-port-race, commits 674c415..f0871c0) DID land cleanly
and is retained — that fix was orthogonal and correctly resolved the
silent-empty-archive symptom that previously masked this deeper bug.

Two doc updates closing the debug session per the resolved pattern this
phase has established (cf. resolved/d12-blob-port-transfer-fails.md and
resolved/webm-playback-freeze.md):
1. **Move debug session to resolved/** with the Resolution section
filled in (root_cause, fix, verification, files_changed). Status
flipped tdd_red_confirmed -> resolved. Original investigation
notes + bisect results + Option C strategy spec all preserved
in-place — the file is the full provenance trail.
2. **Amend 01-CONTEXT.md D-17** with the new port lifecycle commitments.
Append-only (D-17 itself untouched) per the doc cascade rule
established earlier this phase ("amendments append, do not replace,
to preserve SPEC provenance"). The amendment narrates:
- What was Claude's-discretion at Phase 1 plan time has been
specified by Option C.
- The 290 s pre-emptive setTimeout reconnect (Pitfall 4) is RETIRED.
- The architectural commitments added: PING/PONG health probe,
request-id'd REQUEST_BUFFER/BUFFER, SW retry on port replacement,
outer 10 s hard-timeout, operator-visible EmptyVideoBufferError
surface.
- The 4 pinning contracts added (port-health-probe,
request-id-protocol, port-lifecycle-continuous, plus the
refactored port-reconnect-race).
Suite remains 11 files / 53 tests, all GREEN. Quality gates intact.

Phase 1 UAT Test 3 surfaced a two-headed BLOCKER:
(a) silent empty-video archive when save crosses a port-reconnect window,
(b) 3x "Attempting to use a disconnected port object" Uncaught Errors
starting at the 290 s pre-emptive reconnect mark.
Bisect confirmed: H1 (port lifecycle race) was introduced by Plan 01-04
(b064a21); H2 (createArchive silent-skip on empty segments) is an upstream
defect (555eb05) that became fatal once CR-01 + sweep #5 guaranteed the
silent-skip branch would fire on every save during a reconnect window.
This commit lands the 3 RED tests at the unit-test level — they match the
UAT error string byte-for-byte for H1/H1.b and pin the silent-drop
contract for H2. They will flip GREEN as the Option C architectural
refactor (request-id'd port protocol + port-health probe + retry +
operator-visible error surface) lands across the next commits.
Baseline: 8 files / 43 tests (40 GREEN, 3 RED). tsc --noEmit exit 0.

Closes the second debug session in Phase 1's life (after d12). Both
sessions resolved fast — ~30 min for d12, ~15 min for the RED-test
landing in this one — because the planner had explicitly pre-staged
contingencies (D-12 ffprobe gate + D-13 restart-segments skeleton)
for the assumptions RESEARCH.md flagged HIGH-risk. Neither was a
planning oversight; both were the documented HIGH-risk assumption
activating as expected.
Changes:
- Moved .planning/debug/webm-playback-freeze.md →
.planning/debug/resolved/webm-playback-freeze.md (status:
root-cause-confirmed → resolved).
- Added the Resolution section: root-cause one-liner, applied-fix
description, the 5 files-changed list, the 6 fix-a3 commit hashes,
the in-tree verification matrix, and the explicit operator
next-step (re-run ./smoke.sh, verify Chrome playback +
ffmpeg-clean stderr + the 2 webm-playback.test.ts assertions
flipping GREEN, then Phase 1 closes).
- Updated STATE.md frontmatter `stopped_at`, the Decisions log
with a [Phase 01-07-debug-a3] entry summarising D-13 activation
+ the type renames + the retired old-API surface, and the
Session Continuity block (timestamp, stopped_at narrative,
resume-file pointer).
Phase 1 close is still pending operator regen of
tests/fixtures/last_30sec.webm. REQ-video-ring-buffer must not
be marked complete by this commit — Plan 07's §10 #7 acceptance
criterion owns that and only the in-Chrome playback + ffmpeg-clean
stderr (against a freshly regenerated fixture) can close it.
- Mark .planning/debug/d12-blob-port-transfer-fails.md as
status: resolved; fill in the Resolution section with the
applied fix (5 commit hashes, files changed), verification
output (15/15 tests, tsc clean, vite build green, zero
as-any/ts-ignore in fix-touched files), and inline answers
to the specialist-review questions raised by the planner.
Move the file to .planning/debug/resolved/.
- Update STATE.md frontmatter (stopped_at) + Decisions log
+ Session Continuity to record the D-12 fix landing and
the open Plan 07 ffprobe gate (still requires operator
smoke.sh + ffprobe re-run before Phase 1 can close).
- Land smoke.sh — the operator's D-12 acceptance-gate harness
that surfaced the original failure. Self-contained: dedicated
/tmp/mokosh-smoke-profile, auto-accept desktop-capture picker,
Downloads polling, ffprobe gate, fixture staging.
REQ-video-ring-buffer remains NOT-complete — Plan 07 owns it,
operator must re-run ./smoke.sh to verify the fix end-to-end
in Chrome.
