+# ISSUE-CONVERGENCE (owner directive 2026-10-24): issues auto-close when the
+# work that resolves them reaches master. Two roads, both mechanical:
+#
+#   1. KEYWORD ROAD — commit messages containing "closes #N" / "fixes #N" /
+#      "resolves #N" (case-insensitive) close N on the master push that
+#      carries them. Gitea's native auto-close only fires on the default
+#      branch via PR merge; direct pushes to master bypass it — this job
+#      replaces that gap.
+#   2. MENTION SWEEP — issues referenced in landed commit bodies (#N) get a
+#      convergence comment ("referenced from <sha> on master") so the ledger
+#      shows which landed work touched them, without force-closing anything
+#      that isn't keyword-marked. Closing is the author's explicit act; the
+#      sweep just makes references visible.
+#
+# Fail-soft: any API error logs a warning and exits 0 — a failed close must
+# never break the push that landed real work.

+# 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.
