## Launch prompt
|
||
|
||
```
|
||
Implement Feature #14 (F5 cross-rung format + round-trip) per the graduated spec vscode-cowriting-plugin-content/specs/coauthoring-cross-rung-format.md — plan just-in-time from its §7.2 slices, then execute; done = contract + schema published, unit + host E2E green (round-trip, merge, fail-safe, unknown-field preservation all exercised).
|
||
```
|
||
|
||
## Pre-state
|
||
|
||
- `main` clean and pushed; F4 (#12) shipped in session 0012; F5 spec graduated
|
||
in session 0014 (`coauthoring-cross-rung-format.md`, all six forks resolved).
|
||
- Anchor: Feature #14 with an approved Solution Design — R2/R3 gate satisfied.
|
||
- No other sessions in flight (claim peek clean).
|
||
|
||
## Plan
|
||
|
||
Full plan: `docs/superpowers/plans/2026-06-10-f5-cross-rung-format.md`
|
||
(13 tasks; archived to content `plans/` at finalize). Slices → tasks:
|
||
|
||
- SLICE-1 (T1–T3): ajv devDep; `schemas/coauthoring-sidecar.schema.json` +
|
||
`scripts/validate-sidecar.mjs` + schema unit suite; contract doc
|
||
`specs/coauthoring-sidecar-contract.md` in the content repo (INV-14).
|
||
- SLICE-2 (T4–T8): Provenance `email`/`agent.onBehalfOf`; serializer
|
||
unknown-field preservation (INV-15); `isNewerMajor` + store write-refusal
|
||
backstop; `gitUserEmail` identity helper; `VersionGuard` read-only gating
|
||
across all three controllers (INV-16, PUC-4).
|
||
- SLICE-3 (T9): pure `mergeArtifacts` + unit tests of every documented case
|
||
(INV-17).
|
||
- SLICE-4 (T10–T11): `scripts/crossrung-reply.mjs` stand-in + byte-fidelity
|
||
unit test; host E2E round-trip (PUC-2) + newer-major fail-safe (PUC-4).
|
||
- SLICE-5 (T12–T13): README pointers; full gate; PR + merge.
|
||
|
||
Execution mode: inline (superpowers:executing-plans).
|
||
|
||
## Session arc
|
||
|
||
1. **Init** — claimed 0015; baseline verified clean (`main` == `origin/main`
|
||
after pulling our own claim commit); spec read end-to-end; codebase
|
||
surveyed (model/store/controllers/E2E idioms).
|
||
2. **Plan** — just-in-time plan written from spec §7.2 (13 TDD tasks).
|
||
3. **SLICE-1** — ajv devDep (`0ddeaba`); JSON Schema 2020-12 + ajv validator
|
||
script + `expectValidSidecar` test helper, schema suite green (`7c4d3ed`);
|
||
**contract v1.0 published** to content repo
|
||
(`specs/coauthoring-sidecar-contract.md`, `856553a`, pushed) — normative,
|
||
status `living`, with serialization rules, field tables, INV-15/16
|
||
compatibility rules, INV-17 merge rules, conforming-writer checklist,
|
||
changelog.
|
||
4. **SLICE-2** — Provenance `email` + `agent.onBehalfOf` w/ optional-omission
|
||
(`da172a3`); `withUnknowns()` unknown-field preservation at every
|
||
serializer level, byte-stable (`a6b16f0`); `isNewerMajor` +
|
||
`CoauthorStore.update` INV-16 throw backstop (`746071a`); `gitUserEmail`
|
||
(vscode-free, exec git config, fail-open, cached) wired into both
|
||
controllers' `currentAuthor()` (`ef4ec8d`); `VersionGuard` shared across
|
||
the three controllers, gating every write gesture, one warning per doc,
|
||
exposed on `CowritingApi` (`ef7d940`).
|
||
5. **SLICE-3** — `mergeArtifacts` pure reference implementation: union-by-id,
|
||
thread shell/messages split, updatedAt-then-lexicographic resolution,
|
||
conflicts surfaced, differing-major throw (`452f5d1`). One test-expectation
|
||
fix mid-task: the divergent-message test asserted a human-intuitive winner;
|
||
the deterministic tie-break legitimately picks the other side — corrected
|
||
to assert determinism + symmetry.
|
||
6. **SLICE-4** — `crossrung-reply.mjs` stand-in (self-contained foreign
|
||
writer; independent contract serialization; validates before/after;
|
||
refuses newer majors) with byte-fidelity unit test vs the reference
|
||
serializer — passed first try (`e0c127c`); host E2E: editor thread →
|
||
stand-in reply (ELECTRON_RUN_AS_NODE) → external-change → message renders
|
||
at re-resolved anchor (PUC-2); v2 sidecar → warning + bytes untouched
|
||
through edit/save (PUC-4) (`5de59fd`).
|
||
7. **SLICE-5 + ship** — README cross-rung section (`abb9c88`); full gate
|
||
green: typecheck · **98/98 vitest** · build · **18+3 host E2E**. Pushed,
|
||
**PR #15** created via Gitea API and merged (`4651410`); **issue #14
|
||
auto-closed**; branch deleted.
|
||
8. **Operator play feedback** — operator hit the dead "Reply…" input on a
|
||
proposal thread (no submit command wired for `cowriting.proposals`).
|
||
Answered (proposals are decide-only, INV-12; discussion = coauthoring
|
||
thread) and fixed: `canReply=false` + test-facing `RenderedProposal.canReply`
|
||
+ E2E assertion; gate green; **PR #16** merged (`611a180`).
|
||
9. **Operator question (open)** — "show the operator's changes better from a
|
||
diff perspective; easy toggle current ↔ diff view?" Answered with today's
|
||
options (git Open Changes/gutter; F4 proposal diffs; attribution toggle)
|
||
and named the gap: attribution is state-not-history, so a my-changes diff
|
||
needs a baseline snapshot + virtual doc provider + toggle command. Offered
|
||
to capture as a Feature issue; **no answer at finalize** — recorded in
|
||
memory as the open idea.
|
||
10. **Finalize** (goal hook fired on achievement) — plan archived to content
|
||
`plans/2026-06-10-f5-cross-rung-format.md` (`57f5827`); memory
|
||
`f5-cross-rung-shipped.md` written + indexed; this transcript published.
|
||
|
||
## Cut state
|
||
|
||
- Plugin repo `main` @ `611a180` (PR #15 + #16 merged), pushed, no open PRs.
|
||
Working tree clean except `sandbox/playground.md` (operator's play scratch
|
||
— deliberately untouched).
|
||
- Content repo `main` @ `57f5827` (contract + archived plan), pushed.
|
||
Untracked `issues/*.md` capture drafts predate this session (Author's).
|
||
- Issue #14 closed. **Epic #1 fully shipped** (F2 · F3 · F4 · F5).
|
||
- Pipeline (§9): VS Code extension — no deploy stage/PPE/browser surface; the
|
||
app's required tier is host E2E, run green. Nothing deferred.
|
||
|
||
## Deferred decisions
|
||
|
||
- Inline execution chosen over subagent-driven (tasks share heavy
|
||
`model.ts`/serializer context; single coherent feature).
|
||
- Thread-shell divergence rule: lexicographically-larger stable-stringify
|
||
(makes "resolved" beat "open" deterministically) — documented in the
|
||
contract; revisit at team rung if too naive.
|
||
- INV-15 implemented at the serializer level only (spec §6.2 wording);
|
||
controller record-rebuild paths own their records.
|
||
- Stand-in writer deliberately re-implements contract serialization
|
||
(executable documentation); byte-fidelity unit test is the drift tripwire.
|
||
- Merge tie-break is deterministic but not human-intuitive (lexicographic on
|
||
stable-stringify); the divergent-message test was corrected to assert
|
||
determinism + symmetry rather than a particular winner.
|
||
- Diff-view feature idea NOT filed as an issue (operator hadn't confirmed);
|
||
recorded in memory instead.
|
||
|
||
## Operator plate
|
||
|
||
- Reload the extension dev host to pick up the PR #16 fix (rebuild first if
|
||
not running `npm run watch`).
|
||
- Decide on the diff-view toggle idea: capture as a Feature issue, or drop.
|
||
- `sandbox/playground.md` left dirty for you.
|
||
|
||
## Next-session prompt
|
||
|
||
```
|
||
/goal Open a capture session for the diff-view toggle feature (operator's own changes as a toggleable diff vs a turn/accept baseline — sketch in memory f5-cross-rung-shipped), filing it as a typed Feature issue on benstull/vscode-cowriting-plugin
|
||
```
|
||
|
||
(Alternative frontier: the rfc-app#46 Gitea-substrate brainstorming — different
|
||
repo — which consumes the F5 contract as its input.)
