## Launch prompt
Follow-on from session 0018's manual test pass. The operator hit the
"open a tracked workspace document" warning pressing `Ctrl+Alt+D` and asked
"why can't I just open a document and go for it?" — then directed: **make F6
work on any file**, asking where changes would be tracked outside the workspace.
## Outcome
**F6 diff-view toggle broadened to work on ANY file (and untitled buffers).**
Shipped to `main` via **PR #20**; issue **#19** filed and closed. Spec amended to
**v0.2.0** (§11) and pushed to the content repo.
## What landed
- **Own diffable predicate** (`file:` or `untitled:`), decoupled from F2
`isTracked`. `DiffViewController` constructed **before** the no-folder
activation branch → toggle/pin commands always live (work with no folder
open); machine-landing `advance` wiring stays in the with-root branch.
- **Uniform global storage:** baselines moved from `context.storageUri`
(per-workspace) to `context.globalStorageUri` (machine-wide), keyed by
`sha256(documentUri)`. Never the repo (INV-19 holds). `Baseline.docPath``uri`.
- **Untitled buffers:** in-memory baseline only (no durable identity), `(unsaved)`
marker in the diff title; saving promotes to a persisted `file:` baseline.
- Tests: BaselineStore unit re-keyed (104 unit pass); host E2E +out-of-workspace
file (persisted in global storage) +untitled (in-memory) +no-folder activation
(folder-less toggle) → **28 + 4** pass (exit 0), no LLM.
- Docs: spec v0.2.0 amendment; README F6 + MANUAL-SMOKE-F6 updated, incl. fixing
the `Ctrl+Alt+D` wording (it's `Ctrl`, not `Cmd`, on macOS too).
## Turn-by-turn arc
1. **Manual test triage (from 0018).** Operator pressed `Ctrl+Alt+D`, got the
untracked warning. Diagnosed: F6 reused F2 `isTracked` (= saved file inside
the opened folder); the EDH opens `sandbox/`, so only `sandbox/playground.md`
qualified. Explained the rule + the fix.
2. **Design Q&A.** Operator: "make it work on any file — where do we track
changes outside the workspace?" Answered: `context.globalStorageUri`
(machine-wide), keyed by a URI hash; untitled has no durable identity →
in-memory. Surfaced two forks via AskUserQuestion; operator chose **uniform
global storage** + **untitled in-memory**.
3. **New session.** Claimed session 0019; filed issue **#19** as the anchor;
branch `f6-any-file`.
4. **Implementation.** BaselineStore generalized to key-by-hash (docPath→uri);
DiffViewController reworked (isDiffable/isPersistable/uriKey/storageKey,
baseline URI carries the doc URI in its query, self-wired capture-on-open);
extension.ts moved F6 construction ahead of the root check, dropped F6 from
the no-folder stub list, kept advance wiring in the with-root branch.
5. **Tests.** Migrated the E2E surface to URI-string keys; added the three new
cases; updated the no-workspace suite (F6 not a stub; folder-less toggle works).
6. **Docs + ship.** Spec v0.2.0 amendment (pushed to content repo); README +
smoke fixes; PR #20 → merged; #19 commented + closed; branch deleted.
## Cut state
- `main` clean and synced; PR #20 merged; branch deleted; #19 closed.
- Spec `coauthoring-diff-view.md` v0.2.0 on the content repo main.
- Verification: typecheck clean · 104 unit · 28 + 4 host E2E (exit 0) · no LLM.
- **Not done (intentional):** live manual smoke — operator GUI gesture.
## Deferred decisions
- **Spec amendment folded into a planning-and-executing session.** Broadening
F6's scope is arguably a brainstorming/design gesture; the operator made the
design calls live (the two AskUserQuestion forks), so I amended the graduated
spec (v0.2.0 §11) inside this coding session rather than opening a separate
brainstorming session. The amendment is pushed and recorded; flag if you'd
prefer scope changes always route through a distinct design session.
- **Folder-less F6.** Made the toggle work with no folder open at all (controller
constructed before the root check). Beyond the operator's literal ask (which
was about untitled/out-of-folder files *with* a folder open) but the honest
fulfillment of "any file"; low risk, F2F5 untouched.
## Next-session prompt
```
/goal Capture the remaining vscode-cowriting-plugin feature follow-ups — F6 spec §9 deferred items (baseline splicing, named/selectable baselines, changed-line gutter indicators, cross-rung baseline sharing) — and/or assess closing Epic #1 now its F2F6 ladder (+ the #19 any-file follow-up) has shipped.
```
Read first: `memory/f6-diff-view-shipped.md`. No `ROADMAP.md`; Epic #1 is the only
open tracker item.

## Launch prompt
```
Broaden F6 diff-view toggle to work on ANY file (and untitled buffers), not just workspace files. Decisions: uniform global storage keyed by URI hash; untitled buffers in-memory only; F6 gets its own diffable predicate decoupled from F2's isTracked. Continuation of #17.
```
## Deferred decisions
_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Appended as the session runs; surfaced at
finalize. Empty if none._
