+# Spec: Pinned Work in the Tasks Pane (D50 residual 4, #2560)
+
+Status: landed (wave D50-residuals). Supersedes the D50 draft with the
+owner's D51 upgrades.
+
+## The surface
+
+A reserved PINNED WORK area at the TOP of the tasks pane's region
+view — the pane's first content, above the scaffolding status line,
+the work stream, and the queue. It accumulates pinned work native to
+Rune (pin action on work blocks and goals).
+
+- Header: the pin icon + `pinned (N) — outstanding work` label.
+- Each pin renders ONE line: `◆ <plain-english summary>` — every pin
+  carries a plain-english summary of what is pinned (D51 upgrade).
+- Click on the pinned area opens the OUTSTANDING PINNED WORK view
+  (D51 upgrade); click again closes it. In the open view each pin
+  names its id and the controls; clicking a pin (or `x`, which
+  releases the newest) releases it; `esc` backs out to the pane.
+- No pins, no area: the tasks pane renders blank otherwise (D51
+  upgrade), with NO selectable rows anywhere (D51 — the D50 residual 3
+  removal already took the row walker out).
+
+## Keyboard parity (the pin verb)
+
+`ctrl+b` pins the top live work block (the newest running work
+stream block) into the pinned area. Chosen for the control-key idiom
+family — `ctrl+q` steers the queue, `ctrl+g` raises the gauges,
+`ctrl+p` is the palette, `ctrl+a` the activity window — control keys
+own the chrome verbs; plain letters always type (the D36 letter law).
+`ctrl+b` is reachable while composing.
+
+## Persistence
+
+Pins persist across boots through the hot-state store pattern (the
+task_state/history-depth pattern): one JSON document at
+`$RUNE_HOME/tasks_pins.json` (beside `history_depth.json`), written
+atomically (write-beside, rename over) on every pin change; absent or
+corrupt records answer an empty pin set, never a guess. The layer in
+`tui/tasks/pinned.go` stays pure view-model; the shell owns the
+record.
+
+## Tests
+
+`tui/tasks/pinned_test.go` pins the area's placement (first content),
+the no-pins-no-area law, the view open/release cycle with keyboard
+parity, and clone-carry. `tui/cmd/rune-tui/pins_test.go` pins the
+ctrl+b verb and the boot leg (a fresh model loads the pins and renders
+the area).

+# D53 wave report — pane polish + the long-answer format break (Gitea #2568)
+
+Admission: `scripts/admit_wave_d53_pane_polish.py` (classified
+EXISTING_PROJECT_CHANGE, activated, contract
+ADMIT-wave-d53-pane-polish minted — note: the classify core treats
+"listing" as a reading verb; the objective says "showing").
+
+## Per-item outcome
+
+1. **LONG-ANSWER FORMAT BREAK** — reproduced: a 24-block mixed answer
+   at width 24 rendered a table edge row 30 columns wide. Root cause:
+   `tableLines` (tui/chatpane/blocks.go) built edge rows wider than
+   body rows by the separator columns, and the width budget ignored
+   them. Fixed: rows and edges share one geometry, honest
+   too-narrow drop (`total < cols*3` → nil). Summary-first asserted
+   at any length; append-never-reflows asserted on the long answer.
+   Commit 00d55b43 (rode to gitea/master with #2556's push).
+2. **SCROLLBAR** — root cause found: `overlayDisplayCol`
+   (tui/lanes/render.go) wrote the thumb glyph into the left half
+   ONLY when a content rune sat at column x — a short styled row (the
+   common transcript shape) lost the glyph entirely, so no bar ever
+   rendered. Fixed: the glyph lands at the column even past the
+   line's end; thumb styled with a new `RoleScroll` token (vivid
+   #B87C99 / calm #C790AC, floors ≥4.5:1 asserted); chat AND tasks
+   rows render styled-or-empty; wheel step math pinned (one notch =
+   exactly its 3-line step, exact accumulation). Commit 3ea85744.
+3. **QUIT WARNING** — first ctrl+c swaps the composer key hint for
+   the literal `press ctrl+c again to quit`; any other key or the 1s
+   timeout restores the live key hint. Found + fixed a D46 latent
+   defect: the arm-reset check was unreachable dead code inside the
+   KeyPressMsg case — the reset now has its own top-level switch
+   case. The second press quits, never shows the warning. Face chain
+   gained a `Hint()` read-back seam. Commit 7a2a499c.
+4. **DYNAMIC REFLOW** — squash test frozen: a WindowSizeMsg through
+   the face chain re-wraps every block at 44 and 100 columns, no line
+   exceeds the pane, the scroll offset normalizes after the line-count
+   change. The render-path rewrap already held; the test pins it.
+   Commit 6aa271c2.
+5. **INFO BAR** — `context 4.2k/32k (13%)` via `ctxPercent`
+   (clamped 0-100, still silent when the engine never reported).
+   Commit 704b4488.
+6. **COMPOSER STYLING** — key hints render in the new `RoleHintPink`
+   token (vivid #C9739D / calm #D083AC); the activity pane's idle
+   state renders in the new `RoleStateIdle` yellow token (vivid
+   #D9B45B / calm #C9B06E) — the D52 frozen idle test superseded with
+   the ruling recorded. Commits 06302b24 + 71fd16a3.
+7. **SUB-AGENTS** — the activity pane's "sub agents being processed
+   now" section renders ONLY while the syncWaves flight observation
+   reports agents in flight (one poller — the section can never
+   disagree with the rail marker or the wave tab); clickable
+   (mouse.activity.agents region) with ctrl+w keyboard parity,
+   opening the CENTERED agents window (the D52 picker pattern)
+   listing all in-flight agents; the selected row's thought process /
+   recent activity (the factory journal + observations detail
+   `waveRows` already derives) renders beneath; the window is modal
+   (esc/up/down, any other key closes). Plain-value `AgentView` seam
+   keeps lanes un-importable from tasks. Commit f869fa40.
+
+## Verification
+
+- `go test -race -short ./...` green (tui module; the documented
+  pre-existing boot-smoke PTY family aside did not fire this run).
+- gofmt clean; `go vet ./...` clean.
+- PTY proof: the deployed binary boots to CHAT/TASKS panes with the
+  live "enter send" hint (bubbletea coords 0-based-normalized per the
+  D52 finding; click tests drive the region rects directly).
+- Rebased onto gitea/master d054ecb1 (#2556 streaming wave landed
+  mid-flight); items 1-3 rode up with that push; items 4-7 pushed as
+  48d85e16.
+- Deploy: `scripts/build_paired.sh` attested
+  `48d85e16...+20261024T032845Z`; binary installed to
+  `~/.local/share/rune/bin/rune-tui`; `ensure_core` reports real and
+  healthy (identity 'Rune', 13 models).
+
+## Concurrency note
+
+A streaming wave (#2556) edited tui/ concurrently mid-wave. One
+commit initially swept its WIP; it was split back out (the commit was
+mine, unpushed) and item 3 was re-landed from HEAD blobs. The sweep
+race guard caught nothing (staged-tree check passed) — the guard
+checks contract coverage, not authorship. Consider a per-hunk
+authorship check for shared surfaces.

+can alter her code she said she needs shell access, and the ability to
+read and write i want that ability to be in every pane, but when
+something gets to become work it gets promoted into the task pane. she
+also needs tools to be able to connect to git projects. and make that
+native." Doctrine: capability is INHERENT in every pane — the write
+family (write_file, edit_file, run_command) and the new native git
+family ride the wire in CHAT/PLAN/TASK alike; the consent card remains
+the work-promotion mechanism (organization, not permission); the real
+safety layer is the scaffolding authority + contract gates at mutation
+doors. Build: (1) ToolsetFor exposes the full suite in every mode; (2)
+ExecuteGatedTool's write-refusal-by-mode retires, the dispatch-gate
+seam and the genuinely-unavailable refusal stay; (3) the wire tool
+descriptions state the write availability (the model asked for shell
+access because the wire showed read-only — fix the wire); (4) a native
+git family (git_status, git_diff, git_log, git_branch, git_commit,
+git_add) shelling out to git in the repo root (DefaultRepoRoot seam),
+porcelain-parsed honestly, typed JSON results, landing-law banned-path

-4. Deadlock self-heal: the version>tag state (bump landed, tag missed)
-   must plan a repair (create+push the missing tui tag at the fetched
-   tip) — NOT the skip-forever that the pre-fix convergence path
-   produced (which required the manual "re-arm convergence" commit
-   360665b1, 2026-10-19).
+The version-push reader bug: latest_release_tag() sorted ALL tags, so the
+TUI build namespace (tui-v*) could capture the main-line v* range lookup —
+the release-note step then started its range at the TUI tag (cut hours or
+minutes before) and every wave of work vanished from the release body
+("No substantive changes" on a 21-commit day, observed on v0.346.0).
