+yes, let's capture this as a feature. Keep it vague though...there's a lot to think through
+(Context: diff-view toggle for the operator's own changes — current view ↔ diff vs a meaningful baseline; idea raised while playing with the plugin at the end of session 0015.)
+```
+
+## Pre-state
+
+- Session 0015 (F5 #14 shipped) finalized minutes earlier; its closing offer
+  — capture the operator's diff-view idea — answered "yes, keep it vague."
+- Both repos clean on pushed `main` (plugin `611a180`, content `57f5827`);
+  only `sandbox/playground.md` dirty (operator's scratch).
+
+## Session arc
+
+1. **Claim** — 0016 claimed `--type capture`; app + content repo resolved.
+2. **Context** — assembled from the session-0015 conversation (no external
+   signal, no secrets): the gap is that F3 attribution is state-not-history,
+   git diffs against HEAD (wrong baseline), so the operator's own changes
+   have no diff perspective.
+3. **Size-challenge** — one ask; `type/feature` (user-valuable single
+   increment, but design-gated: the baseline fork is load-bearing).
+   Provisional WSJF → `priority/P2`.
+4. **Draft** — `issues/diff-view-toggle.md` written in the content repo
+   working tree, deliberately vague per the operator: scope section parks
+   the four open questions (baseline · snapshot home · whose changes ·
+   relationship to git) for brainstorming; firm non-goals + constraints;
+   solution notes carried as explicitly non-binding.
+5. **Stale goal-hook nudge** — finalize-on-goal fired against session 0015's
+   achieved goal while 0016's draft awaited approval; declined to finalize
+   mid-gate (INV-1 is human-only and posture-independent) and re-surfaced
+   the approval question instead.
+6. **Plugin feedback (side-channel, not session work)** — operator:
+   "Decomposition shouldn't be in Gitea issues — just the solution design."
+   Filed as wiggleverse-dev-claude-plugin **#115** (enhancement/low) via
+   wgl-dev-plugin-feedback; the pending draft's Decomposition section was
+   removed on the spot.
+7. **Approve → file** — operator approved. First filing attempt 401'd: the
+   default `WGL_CAPTURE_TOKEN_SERVICE` Keychain entry doesn't carry
+   git.benstull.org; the host-specific
+   `wgl-gitea-issues-readwrite-token-git.benstull.org` entry does. Filed
+   **Feature #17** — "Diff-view toggle: see the operator's own changes vs a
+   coauthoring baseline" (`type/feature`, `priority/P2`):
+   https://git.benstull.org/benstull/vscode-cowriting-plugin/issues/17
+8. **Finalize** — memory updated (`f5-cross-rung-shipped` + index); this
+   transcript published. Tracked-lite: no spec/plan artifact (INV-6).
+
+## Cut state
+
+- **Feature #17 filed** on benstull/vscode-cowriting-plugin (open — it next
+  needs a brainstorming session, R3).
+- Draft `issues/diff-view-toggle.md` remains **uncommitted** in the content
+  repo working tree (INV-8 — Author's to publish or discard), alongside the
+  pre-existing `issues/f3-*/f4-*/f5-*.md` drafts.
+- Plugin repo untouched this session (`main` @ `611a180`;
+  `sandbox/playground.md` still the operator's dirty scratch).
+- Plugin feedback #115 filed on the plugin's own tracker (untriaged).
+
+## Deferred decisions
+
+- Filed with the host-specific Keychain token service after the default
+  401'd — environment fact recorded in memory (capture scripts could try
+  `<service>-<host>` before the bare service); not filed as its own plugin
+  feedback issue this session.
+- The issue title says "coauthoring baseline" (not "turn/accept baseline")
+  to keep even the baseline vocabulary unbound, per the keep-it-vague
+  directive.
+
+## Operator plate
+
+- Publish or discard the uncommitted `issues/*.md` drafts in the content
+  repo (incl. `diff-view-toggle.md`) at your leisure.
+- `sandbox/playground.md` still dirty in the plugin repo.
+
+## Next-session prompt
+
+```
+/goal Brainstorm Feature #17 (diff-view toggle) into its Solution Design — the baseline fork (turn start / last accept / save / pinned) is the load-bearing decision; constraints and non-goals are in the issue body
+```
+
+(Alternative frontier: the rfc-app#46 Gitea-substrate brainstorming —
+different repo — consuming the F5 contract as input.)
