Session 0046.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-13T08-19 (PST) Type: planning-and-executing End: 2026-06-13T08-31 (PST) Status: FINALIZED. Posture: autonomous (yolo)

Launch prompt

/goal plan-and-execute #48 (pinning the baseline leaves the review panel fully un-annotated — zero-diff → no F3 authorship colors on unchanged blocks; proposals still show)

Plan

#48 (story, P2) — pinning the baseline leaves the review panel fully un-annotated. Anchor: leaf story → §4.3 R2 (no design gate). Picked autonomously as the next backlog item after the document-edit-flow cluster shipped (0043/0044/0045).

When diffBlocks(baseline, current) yields all-unchanged ops (zero diff — the state right after a pin), the F10 on-render still author-colors every block (colorByAuthor), so the panel looks painted instead of clean. Fix: in that zero-diff case render clean (no author coloring, no change marks) while keeping data-src mapping (INV-36) and still injecting pending proposals (proposals are actions, not annotations). Narrow edge case of INV-33 — with-changes render unchanged; off-state unchanged; broader "authorship never colors unchanged" NOT in scope.

Tasks:

1. trackChangesModel.ts renderReview — detect ops.every(unchanged); in that case use a plain render (skip colorByAuthor) for blocks; proposal injection loop unchanged.
2. Unit: baseline==current + author spans → no cw-by-claude/cw-by-human (and no cw-add/cw-del) on the body; with a pending proposal → the cw-proposal block still renders.
3. Host E2E: open preview, diverge + author-color, pin → panel clean (no green/blue); edit again → annotations return.
4. Content repo: one-line INV-33 clarification (zero-diff → clean on-render) in specs/coauthoring-interactive-review.md.

No new persisted artifact; no deploy pipeline (VS Code extension).

Results

#48 (story, P2) shipped to main — PR #52 (merged), issue #48 closed. Picked autonomously after the document-edit-flow cluster (0043/0044/0045).

• trackChangesModel.ts — renderReview gains a pinned RenderOption; when pinned + zero-diff, blocks render plain (skip colorByAuthor).
• trackChangesPreview.ts — pass { pinned: baseline?.reason === "pinned" } from refresh + renderHtmlFor.
• Unit (4 new) + s48PinClean host E2E.

Scoped to the pin specifically (not all zero-diff): a baseline advanced by a machine-landing (accept) is also zero-diff but keeps its authorship coloring (F10 INV-33) — the F10 authorship E2E caught a pure-zero-diff rule would regress accepted-Claude-text coloring, so the clean render is gated on reason === "pinned".

Verification: tsc --noEmit clean; 218 unit green; 74/5 host E2E green.

Session arc

1. Pick + claim. Stop hook required determining/executing the next milestone autonomously (rolling next); chose #48 (leaf story, no design gate) and claimed 0046. Clean main.
2. Read the issue (detailed, gave the solution shape) + renderReview.
3. TDD. Implemented zero-diff-clean; full suite caught the F10 authorship regression (accept advances baseline → zero-diff → coloring was being cleared); re-scoped to reason === "pinned" via a pinned RenderOption → all green.
4. Shipped (PR #52), closed #48; spec clarification written but left in the content-repo working tree (see Deferred decisions).

Deferred decisions

Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Empty if none.

• INV-33 clarification not pushed to the content repo (loose end, not a judgment call). Wrote the zero-diff-after-pin clarification into specs/coauthoring-interactive-review.md, but the content repo has pre-existing uncommitted state that isn't this session's: a modified coauthoring-diff-view.md and ~18 untracked capture-session draft files (issues/*.md, specs/coauthoring-document-edit-flow.md), and local main is 6 behind origin. A clean rebase would require deleting the operator's untracked drafts (irreversible — a STOP gate), so I soft-reset my spec commit into the working tree rather than force it. The clarification sits as an uncommitted modification alongside the operator's other content-repo drafts, for the operator to reconcile/push. The #48 code shipped normally.
