Session 0003.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-10T00-24 (PST) End: 2026-06-10T01-20 (PST) Type: brainstorming Status: FINALIZED

Launch prompt

"Start the next coauthoring feature" → after orienting on the tracker, redirected to brainstorming: there is no Solution Design yet for the inner-loop coauthoring model, and the next feature F2 (#4, region-anchored threads) sits on its still-undesigned git-native persistence + anchoring model — which Epic #1 explicitly earmarks for a follow-on brainstorming session. Operator chose "brainstorm the spec first."

Session opened as planning-and-executing, re-stamped to brainstorming after the orientation made clear the reviewed artifact this session should produce is the spec, not code. Output: specs/coauthoring-inner-loop.md (Solution Design). F2 builds from it in a later session.

Pre-state

• Came off session 0002 (POC #2 shipped, operator-confirmed via F5). main clean.
• Content repo vscode-cowriting-plugin-content initialized (issues/ + plans/), no specs/ collection yet.
• Tracker: only Epic #1 (open) and F1/POC #2 (open). F2–F5 sketched in #1's decomposition, not filed.

Arc

1. Session gate → opened planning-and-executing; claimed session 0003; clean pushed main baseline; org context already wired (0002).
2. Tracker orientation — read Epic #1 + #2 bodies. Confirmed the next feature is F2 (region-anchored threads), not yet filed; #2 still open.
3. Tracker housekeeping (operator approved filing F2): filed F2 → #4 (type/feature/priority/P1); commented + closed #2; updated Epic #1's decomposition (F1 checked, F2 → #4).
4. The fork. F2 sits on the still-undesigned git-native persistence + anchoring model, which Epic #1 earmarks for a follow-on brainstorming session, and there is no spec. Surfaced the choice (brainstorm spec first vs. build F2 with a provisional format). Operator chose brainstorm the spec first → re-stamped session 0003 to brainstorming.
5. Brainstorming dialogue (superpowers:brainstorming), one decision at a time — all four resolved by the operator:
   • Depth = threads-deep + model-wide skeleton (shared anchors/provenance; F3/F4 as accommodated extension points).
   • Persistence = .threads/<path>.json committed sidecar (not git notes / trailers).
   • Anchoring = hybrid (live offsets + durable content fingerprint; orphan fallback, never silently moved).
   • Agent in F2 = none (no live @cline/sdk turn / no credentials; agent provenance author reserved for F3/F4).
6. Presented the consolidated design → operator approved.
7. Wrote the Solution Design specs/coauthoring-inner-loop.md (focused: §6 the meat — envelope, provenance primitive, hybrid anchoring, 5 invariants; §7 SLICE-1..5). Self-review passed; operator reviewed and approved.
8. Finalize (brainstorming). Base survey clean. Artifact guard ✓. submit-spec.sh --status graduated published the spec to the content repo specs/ collection (976fb48) — the content repo's first specs/ entry.

Cut state

• Spec graduated: vscode-cowriting-plugin-content/specs/coauthoring-inner-loop.md (status: graduated), content repo main at 976fb48. The reviewed input to building F2 (#4).
• Code repo vscode-cowriting-plugin: clean, in sync — no code this session (deliberate; F2 builds next session).
• Tracker: Epic #1 (open, F1 checked / F2 linked), F1/#2 (closed), F2/#4 (open, next).
• §9 pipeline: N/A — brainstorming produced a spec, nothing deployable.
• Lineage not re-read: ben.stull/rfc-app#48/#46 live on the wiggleverse host and weren't reachable from git.benstull.org this session; Epic #1's distilled summary stood in. Noted in the spec's Source artifacts.

Operator plate

• Next session builds F2 (#4) from the graduated spec (see next-session prompt).
• Repo visibility: both repos still public on Gitea (carried from 0001) — confirm if unintended.

Next-session prompt

/goal Build F2 (#4) — region-anchored threads — in a planning-and-executing session: write the just-in-time plan from vscode-cowriting-plugin-content/specs/coauthoring-inner-loop.md (§7.2 SLICE-1..5: CoauthorStore → Anchorer → ThreadController via the Comments API → reload/external re-anchor → @vscode/test-electron E2E) and execute it. UI surface ⇒ E2E host tests are first-class plan tasks. No live @cline/sdk turn / no provider-auth in F2.

Deferred decisions

• Brainstorm-first vs. build-F2-directly (operator-resolved). F2 sits on the undesigned shared model; rather than default a provisional format autonomously, surfaced the fork → operator chose brainstorm the spec first, redirecting the session type. No low-confidence autonomous calls were left unflagged. (Filing F2, closing #2, and editing Epic #1 were done with operator approval to file F2.)
