Append Amendment blocks to DEC-003 (getDisplayMedia replaces tabCapture)
and DEC-010 (long-lived port replaces alarms keepalive) so downstream
phases see the new API contract. Original text intact; amendments are
appended, not replacements. Maintains intel/* provenance for the
Phase 01 doc cascade.
After gsd-plan-phase 1: 7 plans across 7 waves. All gates pass:
- Plan-checker (sonnet) VERIFICATION PASSED on iteration 1
- Decision coverage gate (gsd-sdk): 19/19 decisions covered
- Requirements coverage: REQ-video-ring-buffer in all plans
- Security threat model: T-1-01/02/04 mitigated; T-1-03 accepted residual
Known non-blocking gaps:
- gsd-sdk roadmap.annotate-dependencies failed (t.trim is not a function);
ROADMAP plan-list annotations skipped. Phase 1 plan-list in ROADMAP.md
remains accurate; this is a cosmetic nice-to-have for cross-cutting
constraint visibility.
- 1 plan-checker warning (stale wave prose in Plan 03/04 objectives) was
fixed during decision-coverage revision.

Renames "## Open Questions" header to "## Open Questions (RESOLVED)" and
adds inline RESOLVED markers to each of the three questions:
- Q1 (MediaRecorder timeslice cluster alignment) → D-12 ffprobe gate
(Plan 03 Task 2 + Plan 07 Task 1) + D-13 fallback (pre-staged skeleton
in src/offscreen/recorder.ts per Plan 03)
- Q2 (5-minute port lifetime cap) → Plan 04's 290 s pre-emptive reconnect
plus synchronous onDisconnect → connectPort reconnect path
- Q3 (crxjs path-emit behavior) → Plan 06 Task 2 runtime verification +
conditional src/background/index.ts edit

Two changes:
1. wave: 3 → 6 (cascade: max(wave(05)=4, wave(06)=5)+1 = 6).
2. Task 1 <automated> verify now prefixes the ffprobe invocation with
test -f tests/fixtures/last_30sec.webm && which ffprobe so the gate
fails fast with a clear signal if the human checkpoint never produced
the fixture (instead of ffprobe blowing up with a cryptic file-not-found).

Three changes to resolve the blocker:
1. depends_on: ["03"] → ["03", "05"] — Plan 06 Task 2 conditionally edits
src/background/index.ts which Plan 05 writes; the original wave 2
collocation with Plan 05 was a same-wave file conflict.
2. wave: 2 → 5 (cascade: max(wave(03)=2, wave(05)=4)+1 = 5).
3. files_modified gains src/background/index.ts (Task 2 path-adjustment
edit is now declared in frontmatter so the executor sees the contract).

Plan 05 depends_on: ["03", "04"], so wave must be max(2, 3)+1 = 4, not 2
(cascade from Plan 04 wave change).

Two changes:
1. wave: 1 → 2 (cascade after Plan 02 wave fix)
2. OffscreenLogger: ...args: any[] → ...args: unknown[] for strict-mode
hygiene. Existing Logger / ContentLogger are left on the legacy any[]
pattern (refactoring is out of Phase 1 scope) — divergence documented
via style_divergence_note frontmatter field.

Documents that all 6 tasks are doc-text-only edits with no TypeScript
compilation — cognitive load is substantially lower than code plans of
equal task count. Avoids fragmenting the atomic doc-cascade by splitting
into 01-01a / 01-01b.

Researched Chrome MV3 offscreen + DISPLAY_MEDIA, MediaRecorder cluster
alignment, SW port keepalive, crxjs offscreen entry, ffprobe verification.
Identified the D-12/D-13 fallback hinge: timeslice=2000ms does NOT force
keyframe alignment (Chrome kf_max_dist=100); Pattern 2 (age-trim) may need
to escalate to Pattern 3 (restart-segments) if ffprobe rejects.
Architecture verified against two in-the-wild production extensions
(Proscreen-S3, meeting_mate) using the exact CONTEXT.md D-01..D-05 path.
The OFFSCREEN_READY handshake (audit P1 #12) and long-lived port keepalive
(audit P1 #8) are wired together. .planning/phases/01-stabilize-video-pipeline/01-RESEARCH.md

Settings chosen for the Mokosh stabilization work:
- model_profile: quality (Opus everywhere except verification)
- git.branching_strategy: phase (gsd/phase-{N}-{slug} per phase)
- workflow.code_review: true with depth=deep (cross-file analysis with
import graphs — appropriate given the SW ↔ offscreen ↔ content-script
messaging interplay)
- workflow.tdd_mode: true (RED/GREEN/REFACTOR gates for eligible tasks,
retrofits regression coverage as we touch each file)
All other settings inherit gsd-sdk defaults (research/plan-check/verifier
on, balanced commit_docs, no Intel/Graphify indexing yet).

Preserves the explicit-manifest input used to bootstrap .planning/ so the
ingest is reproducible. Two docs were classified: Тз расширение фаза1.md
(SPEC, precedence 0) and README.md (DOC, precedence 1).
