## Launch prompt
Continuation of the same conversation as session 0025 (which shipped F8). The
operator reported friction: **"It's not showing the Claude-composed annotations in
the preview."** Debugging clarified it was a *feature gap*, not a regression — the
F7 preview is author-agnostic by design. This session designed and shipped the fix:
**F9 — an Authorship mode in the rendered preview**.
## Pre-state
- F8 shipped (session 0025, PR #26); `main` clean.
- Debugging (systematic-debugging) found: `renderTrackChanges` diffs only baseline
vs buffer (no attribution), and the F6 baseline advances on machine-landing
(INV-18), so Claude's accepted text reads as "unchanged". → an authorship axis is
needed, read from F3.
- `AskUserQuestion` settled the design: a **toggle** (changes ⟷ authorship),
**inline char-precise** marking, **both authors** colored (Claude blue / human
green), **block-level** badges for code/mermaid fences, **segmented header toggle**.
## Plan
Brainstormed the design (`superpowers:brainstorming`) → spec
`docs/superpowers/specs/2026-06-11-authorship-preview-design.md` (INV-26..28).
After operator approval, wrote the plan (`superpowers:writing-plans`) →
`docs/superpowers/plans/2026-06-11-f9-authorship-preview.md` (7 TDD tasks) and
executed inline (`superpowers:test-driven-development`).
## Turn-by-turn arc
1. **Debug (read-only):** read the full F7 + F3 stack; identified the feature gap +
baseline tension. Confirmed with the operator via AskUserQuestion ("mark what
Claude wrote" → attribution-aware preview).
2. **Brainstorm:** four design decisions locked (axis=toggle, granularity=inline,
scope=both authors, fences=block badge, toggle=segmented header). Wrote +
committed the spec; operator approved.
3. **Claim 0026** (planning-and-executing) before implementation.
4. **SLICE-1/2 (Tasks 12):** `splitBlocksWithRanges` (block source offsets) + pure
`renderAuthorship` — PUA sentinel injection through markdown-it, atomic fences,
adjacent-span ordering. 29 model unit tests.
5. **SLICE-2 (Tasks 34):** `AttributionController.spansFor`; preview gains the
attribution dep + per-panel mode + `setMode`; `extension.ts` reorder.
6. **SLICE-3 (Task 5):** webview segmented toggle + legend + `.cw-by-*` CSS.
7. **SLICE-4 (Tasks 67):** host E2E (authorship marks Claude's landed span +
track-changes regression) + manual smoke + README.
8. **Ship:** PR **#27** merged to `main`; `main` synced; 161 unit + 37/5 host E2E
green. Plan archived + spec graduated to the content repo.
Notable hiccup: the PUA sentinels are invisible characters — they round-tripped
correctly through the Write tool (verified via `cat -v`), but a couple of test
regexes and a doc literal needed explicit `..E003` escapes for clarity.
## Cut state
- F9 merged to `main` (PR #27). Spec graduated + plan archived (content repo).
- Tests: 161 unit + 37 (with-ws) + 5 (no-ws) host E2E green.
- Core files (`model.ts`, `store.ts`, `mergeArtifacts.ts`, `diffViewController.ts`,
`baselineStore.ts`) untouched; track-changes mode behavior unchanged.
- VS Code extension → no PPE/prod stage; done = merge + tests green.
## Deferred decisions
- **F9 typed/built without a captured tracker issue** — it came from a conversational
bug report; PR #27 carries the record. A retro Feature issue would tidy the tracker.
- **Inline (not block-level) authorship marking** — the operator chose inline
precision; the residual risk (a sentinel adjacent to `**`/`_` perturbing that
span's markdown) is rare, fails soft to a per-block chip, and hardening is deferred.
- **Session 0024 still unfinalized** — the finalize-on-goal hook flagged it twice;
the operator deferred the cleanup (declined a finalize detour). Still an open
`--INPROGRESS` needing an adopt-and-finalize pass. Plus #21/#1 issue-status hygiene.
## Next-session prompt
```
/goal plan-and-execute #22 (F7 intra-diagram mermaid diffing — node/edge-level diff beyond the whole-diagram "changed" badge), per Feature #22
```
Read [[f9-authorship-preview-shipped]] for the render/wiring surface. Consider
finalizing session **0024** first (a one-step adopt-and-finalize) and the #21/#1
issue hygiene.
