## Launch prompt
|
||
|
||
```
|
||
plan-and-execute #22 (F7 intra-diagram mermaid diffing — node/edge-level diff
|
||
beyond the whole-diagram "changed" badge), per Feature #22.
|
||
```
|
||
|
||
## Outcome (one line)
|
||
|
||
Task **#22** — intra-diagram mermaid diffing — shipped to `main` via **PR #28**
|
||
(issue auto-closed); 3 new pure host modules + render wire-in; **189 unit + 38/5
|
||
host E2E** green; design §11 (INV-29..31) + plan archived to the content repo.
|
||
|
||
## Pre-state
|
||
|
||
- `main` clean & pushed; Epic #1 + F2–F9 shipped (last: F9 authorship preview,
|
||
PR #27, session 0026). #22 (F7's deferred intra-diagram task, `type/task`) open.
|
||
- F7 render engine in place: `src/trackChangesModel.ts` (pure block diff, mermaid
|
||
fences **atomic** per INV-23, whole-diagram "changed" badge) + sealed webview
|
||
(`media/preview.ts` runs `mermaid.run()`) + `TrackChangesPreviewController`.
|
||
- Carried-in loose ends: session 0024 unfinalized; a stray untracked
|
||
`specs/coauthoring-out-of-workspace.md` in the code repo working tree.
|
||
|
||
## Arc (turn by turn)
|
||
|
||
1. **Init.** Claimed session 0027 (no in-flight sessions). Verified clean pushed
|
||
`main`. Read memory resume pointer (Next /goal = #22).
|
||
2. **Gate (§4.3).** Confirmed #22 is `type/task` — a leaf, eligible
|
||
planning-and-executing anchor (R2); no separate Solution Design required.
|
||
3. **Brainstorming (superpowers).** Explored the F7 architecture to ground the
|
||
design. Resolved the four forks the issue flagged:
|
||
- **Diff level → parsed-graph** (source-text defeats a *rendered* preview; SVG
|
||
diff is layout-brittle — §6.7 already rejected it). Parse → diff → re-emit the
|
||
current source augmented with mermaid's *own* styling directives, keeping the
|
||
host pure (INV-22) and the webview unchanged (INV-21).
|
||
- **Layout reflow → accepted** (no position pinning; mermaid exposes none).
|
||
- Asked the operator the two genuinely-open forks via AskUserQuestion:
|
||
- **Removed elements → "ghost in place"** (faded/dashed, re-injected at
|
||
baseline position).
|
||
- **Diagram scope → "flowchart + sequence"** (broader than my flowchart-only
|
||
recommendation); all else → v1 badge fallback.
|
||
- Surfaced a real mermaid constraint: sequence diagrams have **no per-message
|
||
color hook** → use `rect rgb(...)` tinted bands (the only option).
|
||
- Wrote the design as **§11** of the F7 spec (content repo) + INV-29..31.
|
||
4. **Plan (superpowers:writing-plans).** 9 TDD tasks → `docs/superpowers/plans/2026-06-11-f7-intra-diagram-mermaid-diff.md`.
|
||
5. **Execute (superpowers:executing-plans, inline).** Feature branch
|
||
`f7.1-intra-diagram-mermaid-diff`; one commit per task:
|
||
- `mermaidDiff.ts` (dispatch + `detectDiagramType` + total try/catch fallback;
|
||
owns `CW_COLORS`).
|
||
- `mermaidFlowchartDiff.ts` — `parseFlowchart` + `diffFlowchart` →
|
||
`classDef`/`class`/`linkStyle`, ghost nodes/edges re-injected.
|
||
- `mermaidSequenceDiff.ts` — `parseSequence` + `diffSequence` (LCS via jsdiff)
|
||
→ `rect` tinted runs, removed messages/participants ghosted.
|
||
- Wired into `renderOp`'s changed-atomic-mermaid branch (`mermaidFenceBody`
|
||
helper + `MERMAID_LEGEND`); legend CSS; `renderHtmlFor` E2E seam.
|
||
- Updated one pre-existing unit test that asserted the *old* v1 badge for a
|
||
changed flowchart (now augments — exactly what #22 changes).
|
||
6. **Verify & ship.** typecheck clean, 189 unit, 38/5 E2E. PR #28 opened on Gitea
|
||
(needed the repo-scoped keychain token — the issues-only token lacked
|
||
`read:repository` scope), merged to `main`, branch deleted, #22 auto-closed.
|
||
7. **Spec reconcile.** The local content clone was 6 commits stale (remote had the
|
||
*graduated* F7 spec + F8/F9). Aborted a conflicting rebase, reset local to
|
||
origin, re-applied §11 cleanly onto the current spec, pushed (`1c2844d`).
|
||
8. **Operator Q (mid-finalize):** asked about the macOS "VS Code would like to
|
||
access data from other apps" prompt → explained it's the TCC cross-app-data
|
||
gate triggered by my Keychain reads (`security` CLI fetching the Gitea token),
|
||
not the file edits; gave Allow/Don't-Allow trade-offs.
|
||
9. **Finalize.** Archived the plan to the content repo `plans/` (`6b14de9`);
|
||
updated memory; published this transcript.
|
||
|
||
## Cut state
|
||
|
||
- `main` (code): PR #28 merged (`06d4f87`), clean & pushed. Only the carried-in
|
||
stray `specs/` dir remains untracked (not this session's).
|
||
- Content repo: F7 spec §11 (`1c2844d`) + archived plan (`6b14de9`) pushed.
|
||
Untracked `issues/*.md` are pre-existing capture drafts, untouched.
|
||
- Issue #22: **closed**. No open issues remain.
|
||
|
||
## Deployment pipeline (§9)
|
||
|
||
**No pipeline stage applies.** This app is a VS Code extension with **no
|
||
flotilla/cloud infra** (`app.json`: code/specs/roadmap/sessions repos only).
|
||
localhost + E2E (host) ran green; there is no PPE/prod deploy stage to gate.
|
||
Done = merge + green tests.
|
||
|
||
## Deferred decisions
|
||
|
||
_Autonomous-mode low-confidence calls; none material this session._
|
||
|
||
- The two product-flavored forks (removed-element treatment, diagram scope) were
|
||
**not** auto-decided — they were put to the operator via AskUserQuestion and
|
||
answered (ghost-in-place; flowchart+sequence). Everything else had a clearly
|
||
preferred answer and was decided autonomously.
|
||
- Updated one pre-existing unit test to the new behavior (judgment call, low risk):
|
||
a changed flowchart now augments rather than showing the whole-block badge.
|
||
|
||
## Operator plate (loose ends to pick up)
|
||
|
||
- Session **0024** still unfinalized (carried since session 0025).
|
||
- Stray untracked `specs/coauthoring-out-of-workspace.md` in the **code** repo —
|
||
a duplicate of the F8 spec that already lives in the content repo.
|
||
- F9 was never captured as an issue; #21 / #1 issue hygiene.
|
||
- Manual webview-render smoke for F7.1 (`docs/MANUAL-SMOKE-F7.1.md`) not yet run
|
||
by a human (colors paint — not auto-testable in the sealed sandbox).
|
||
|
||
## Next /goal
|
||
|
||
No open issues and no roadmap-driven next feature remain. Suggested next:
|
||
a **capture session** to re-stock the backlog from the deferred F7 follow-ups —
|
||
more mermaid diagram types for #22 (class/state/ER/gantt), preview→source
|
||
scroll-sync, non-markdown rendered views — and to clear the hygiene loose ends
|
||
above. Or pick one deferred item directly to plan-and-execute.
