Summary

Cycle 0049's third and last pull request (Refs #107; PR-A #113 and PR-B1 #116 merged before it). A test replay now shows the source that executed at the selected moment, with the native debugger at that same moment, and no move ever puts two moments on the screen.

• Recorded-source tab (Design 4, DS5). One Codebook-owned document per test replay, Captured-<file name>, holds a verified stop's sealed source with the stopped line highlighted and labelled Recorded: <path>:<line> · <t> s. The replay debugger's thread reads Recorded test stop <n> · <path>:<line> and its frames open the tab. At an output, at the result and at an unverified stop the tab holds the 4A placeholder, written as comments so the editor reports no problem for it. A stop in a file with another name renames the tab; every other slot tab closes after a slot shows, and returning to Live or opening another saved study closes it. A tab that cannot open shows a Study row with Retry and writes an Output entry.
• Selection order (EN8, EN9). Each move leaves the earlier moment on the debugger and the tab first, confirms the new bytes in the tab, presents the debugger at the tab, then commits the line, label, Study position and Application output together; the reader position is written after the commit. A moment without a stop always empties a running debugger, so a stop an overtaken selection presented never stays beside it (Step 11's P1).
• Timeline and pacing (E1, DS11). The slider marks the range from the first to the last event as unrecorded with a tick per verified stop (one drawing shared with the browser transport, its golden DOM identical), and Play waits at most 1.5 s per event without pausing or asking across an unrecorded interval.
• Fixes found while shipping: orphan slot tabs after an overtaken or failed rename (F163), two pnpm health findings in the Study client (F177), the slot's failure row after Live (F164), the stale debugger stack after a quick reversal (F193), Retry during a browser replay (F194), and a test's teardown race (F195).
• Documents: the extension README's recorded-source tab, slider and Play paragraphs; the root README's status; AGENTS.md's Stage-1-only pre-gate rule (owner, 2026-10-22).

Screenshots

From the source-slot spike in the macOS Space (candidate c66e3f6, before the later review fixes; saved test replays recorded through Codebook's tools without a chat). Motion and the region-2 comparison are N49's, after this merge.

Pre-Landing Review

/ship ran three fixing cycles and stopped with converged:false (the owner's order: the open Critical and Major defects are recorded in Issue #107's comment, the last review's critical findings are fixed, and the pull request merges after required CI).

Pass	Reviewers	Fixed	Carried
1	core, 6 specialists, red team, QA	F163 (critical, orphan slot tab), F177 (pnpm health)	F164 to F176
2	core, 6 specialists (four dispatched again to read the whole diff), red team, QA	F164 (Step 7's red test)	F178 to F185
3	6 specialists and red team, each reading the whole diff; QA through the recorder	none (converged)	F186 to F192
4 (Step 11's fixes)	reuses pass 3's review of the identical tree; QA on the fixed tree	F193, F194, F195	F196 to F202

Gate edits: none detected (38 listed, 26 read; patterns: RH-1,RH-3,RH-4,RH-12,RH-13,RH-14,RH-15,RH-16; unlisted idioms: none)

Outside review: Codex adversarial (gpt-6-astra) completed with one High (the stale debugger stack, fixed as F193) and three Medium (carried F196 to F198); Codex structured review completed, GATE: PASS (two P2, fixed as F193 and F194); Claude adversarial completed (nine findings, its recommendation F193). Step 11.5's binding is mismatched by design: the tree changed after Step 11 with these fixes, and Step 16 and required CI verify the final tree.

Exploratory QA

Functional surface (the workspace and utilities through Node's runner; Reader DOM through its CLI), smoke 5 probes plus the plan checks, in each pass:

• Pass 1: pnpm health failed with two findings beyond its baseline (F177), fixed and rerun green.
• Pass 2: the F164 red test reproduced and fixed; the Reader DOM wiki-reader-dom 720 px case failed once (F135, a known flake; this pull request changes no Wiki file) and passed on replay.
• Pass 3 (1d6c14c): every capture passed through the recorder (verdict pass).
• Pass 4 (c22dc14, cae9b10): smoke, static gates, pnpm test, Reader DOM pass; pnpm health's coverage run failed one PR-B2 test's teardown (F195), fixed; pnpm health exit 0.

No native editor surface here: native slot placement passed in the spike (Issue comment 6343288678); motion and the chat-driven round are N49's.

Design Review

No frontend files changed by the design lens's scope — design review skipped (the Study webview's coverage-strip drawing moved into shared helpers with its golden DOM identical; Reader DOM checks cover it).

Eval Results

No prompt-related files changed — evals skipped.

Scope Drift

Scope Check: CLEAN

Plan Completion

Plan version 7, PR-B2 items (re-audited after the fixes): 21 items, 14 done, 1 changed (the placeholder and loading text are line comments after the spike), 3 partial, 0 not done, 3 unverifiable.

• Partial, carried: EN8 step 1's Application loading header at a move; AC6's ownership tests (1 of 2); no unverified-stop placeholder test on the slot and real waits instead of an injected clock for the 1,000 ms bound.
• Unverifiable here: the spike (PASS in both hosts, Issue comment 6343288678); the documents and version, now in this pull request; N49, which runs after the merge and does not gate it.

Verification Results

Step 8.1 obligations executed in Step 9 and Step 16: format:check, typecheck, lint, health:static, dupes, dead-code PASS; pnpm test PASS (5,700 tests, 0 failed); pnpm test:package PASS (1,069 tests, 0 failed); pnpm health alone PASS (exit 0, score 85 A); Reader DOM five checks PASS; build, package and check-package PASS (VSIX 1,924,738 bytes, SHA-256 4848bda85ebc9c4587db784d69106b888c154229ed462e1e74a0630b6fb7dc1a); pre-gate Stage 1 PASS with one warning (a 10-digit process id in a test title read as a phone number). NOT RUN: N49 (after the merge); Windows and Linux.

Documentation

Scope: reviewed committed, unstaged and selected docs for Cycle 0049 PR B2 (base 60aff4b, head cae9b10), plus the release-metadata edits in the working tree. The kept documents are AGENTS.md, CHANGELOG.md, PRODUCT_GOAL.md, README.md, extension/README.md and the bundled SKILL.md. I also read docs/agents/*.

Result: the 0.2.35.0 CHANGELOG entry covers the recorded-source tab, the native debugger at the selected moment, one moment at a time, the slider's unrecorded span and ticks, and Play's 1.5 s bounded wait. Every user-visible behavior it names has a matching sentence in extension/README.md. Those sentences were already updated, including the numbered walkthrough. The root README.md implementation status already carries 0.2.35.0 and describes the third pull request. AGENTS.md gained the owner's pre-gate rule and has no stale content. The bundled SKILL.md (1.0.46) and the API (1.8) are unchanged, and nothing in the diff affects them. I corrected one stale line, the package:check example filename in extension/README.md (0.2.34 to 0.2.35).

Debt: none found. The CHANGELOG's Not observed section already records what remains unverified: a chat-driven run of this version, motion between moments, and Windows and Linux.
