+### #2535 — PANE-OWNED SCROLLING + COMPOSER OWNERSHIP + ANSI COMPOSITION (owner, 2026-10-22, fixes #2535)
+1. PANE-OWNED SCROLLING (supersedes any D35-era composer-history wording): the chat transcript and the task surface (the lanes task list while the tree region is closed; the open task tree when open) each own their own scroll display state, and history lives in the pane. PageUp/PageDown and ctrl+up/ctrl+down route to the FOCUSED pane; the mouse wheel routes to the pane under the pointer (region hit-test over the face's current frame) regardless of keyboard focus; one wheel detent ≈ 3 lines. Chat upward exhaustion still grows the bridge's poll depth (the /history law's live leg). Boundary chrome (promote region, rail takeover, semantic modal) declines pane scrolling while it owns the input.
+2. THE COMPOSER OWNS NO SCROLLING AND NO SENT-INPUT RECALL: Up/Down in the composer edit/move within the draft (multiline cursor motion) or sit at a boundary — they never recall prior submissions. Submission recording and persistence remain for file compatibility. No scrollbar, no scrolling state, nothing overflows into the composer: no pane thumb may land at or below region.input.
+3. ANSI COMPOSITION (the layer law made concrete): the pane border cells are styled independently of the content layer — a nested SGR reset in content can no longer neutralize an outer border color (the right-edge grey-where-pink-should-be defect). Region overlays (tree, skills, promote, changes) splice at DISPLAY columns through tui/semantic.SpliceDisplay with whole-run tokenization; the rune-indexed splice copies are retired. Frozen fixtures updated only where they had baked the byte-level leak in (reorder-mid-flight: 34 leaked interior columns; skills-region: severed-escape fragments) — plain sentences and visual semantics unchanged.
+4. OVERLAY-OBSERVER PARITY: gauges/picker overlays are transparent to wheel, click, AND page keys (View-level composition, no region insertion of their own — card buttons are the exception that PROVES the rule: their y/n click regions are explicit, the wheel dispatch still only routes the three pane regions). Parity by construction: the wheel dispatch routes ONLY region.chat/region.tasks/region.tasks.tree, so an overlay can never scroll a pane behind it. The lanes chat scroll offset's honest observer is the STATE pass-through (ChatScrollOffset through lanes → rail → promote → tasks), not the rendered frame: under chrome the frame belongs to the takeover.

+# Issue #2535 Pane Scrolling and Border Isolation Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use compose:subagent (recommended) or compose:execute to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make chat and task history genuinely scrollable by pane, remove sent-input-history navigation from the composer, and prevent nested ANSI content from leaking terminal-default grey into pane borders.
+
+**Architecture:** Scrolling remains renderer-owned display state. Chat keeps its existing `chatpane.scrollState`; the lanes task list gains a viewport, while the open task tree uses its existing `view` window through explicit scroll APIs. The shell dispatches keyboard scrolling by focused pane and mouse-wheel scrolling by hit-tested pane region. Borders style each edge cell independently from content.
+
+**Tech Stack:** Go 1.25, Bubble Tea v2, Lip Gloss v2, Rune semantic frames/regions, Go tests.
+
+## Global Constraints
+
+- Gitea issue **#2535** is the sole ledger; #2546 is a closed duplicate.
+- The shared composer owns text editing only: no pane scrollbar, page scrolling, wheel scrolling, or sent-input recall.
+- `PageUp`/`PageDown` and `Ctrl+Up`/`Ctrl+Down` target the focused pane; mouse wheel targets the pane under the pointer.
+- Wheel input over `region.input`, menus, the thinking bridge, info chrome, or outside a pane is a no-op.
+- Scrolling chat above the held window preserves the existing deeper-history fetch.
+- Task viewport state is display state and must not enter semantic fingerprints or persisted task authority.
+- The open task tree and the closed lanes task list must both scroll; changing a hidden lanes list is not success.
+- Scrollbars stop above `region.input`; the composer must never contain `▐`.
+- Focused pane and composer borders remain pink; the intentionally unfocused pane remains color 240 grey.
+- Nested ANSI resets inside content may not alter either outer border cell.
+- No unrelated TUI redesign or module split.
+
+## Findings and feasibility
+
+- Chat already has complete line-offset/page state in `tui/chatpane/scroll.go`; this leg is routing work, not a rewrite.
+- The task lanes scrollbar is selection-derived decoration, not a viewport. `taskContent` renders all rows and `drawPane` truncates the tail.
+- The open task tree overlays the lanes task pane and has a `view` field, so it needs a separate public scrolling path.
+- The shell handles clicks but drops `tea.MouseWheelMsg`.
+- Composer `Input3` explicitly owns sent-history browsing, conflicting with the newer owner ruling.
+- `drawPane` styles `│ + content + │` as one run; a nested SGR reset cancels the style before the right border.
+- Feasibility: high (0.9). Estimated implementation and verification: 2–4 hours. Main risk: keeping open-tree and closed-list viewport semantics aligned without changing semantic state.
+- Baseline: `lanes`, `chatpane`, `nav`, and `tasks` pass. `cmd/rune-tui` has three pre-existing PTY/live failures (boot bridge timeout, consent flow timeout, model pane exit timeout); do not attribute those to this branch without a before/after delta.
+
+---
+
+### Task 1: Remove composer history navigation and isolate border cells
+
+**Covers:** composer ownership; grey-border defect.
+
+**Files:**
+- Modify: `tui/nav/input3.go`
+- Modify: `tui/nav/input3_test.go`
+- Modify: `tui/cmd/rune-tui/main_test.go`
+- Modify: `tui/lanes/render.go`
+- Modify: `tui/lanes/lanes_test.go`
+
+**Interfaces:**
+- Preserve: submission recording and `History() []string` for file compatibility.
+- Remove: sent-history browsing ownership from Up/Down.
+- Produce: border rows whose left and right cells each reassert the pane border style.
+
+- [ ] Add `TestInputArrowsNeverRecallSentHistory`: submit two values, type a draft, press Up/Down, and prove the draft is never replaced by a historic submission.
+- [ ] Add `TestNestedANSIResetCannotResetPaneBorder`: render styled content ending in SGR reset; prove both vertical edge cells locally carry pink when focused and color 240 when unfocused.
+- [ ] Run the exact new tests and observe failures caused by history recall and right-edge style reset.
+- [ ] Delete `stash`, `browsing`, `idx`, `browseUp`, `browseDown`, and `exitBrowsing`; route Up/Down only through multiline cursor movement/no-op-at-boundary.
+- [ ] Change `drawPane` interior rows to `style.Render("│") + content + padding + style.Render("│")`; retain wholly styled top/bottom borders.
+- [ ] Run `go test ./nav ./lanes ./cmd/rune-tui -run 'InputArrowsNeverRecall|NestedANSIReset|Composer'` from `tui/` and observe green.
+
+### Task 2: Add genuine task viewports to both task surfaces
+
+**Covers:** task-pane history/work-stream scrolling; scrollbar accuracy.
+
+**Files:**
+- Modify: `tui/lanes/lanes.go`
+- Modify: `tui/lanes/render.go`
+- Modify: `tui/lanes/lanes_test.go`
+- Modify: `tui/rail/rail.go`
+- Modify: `tui/promote/promote.go`
+- Modify: `tui/tasks/face.go`
+- Modify: `tui/tasks/render.go`
+- Modify: `tui/tasks/face_test.go`
+
+**Interfaces:**
+- Produce on the face chain: `ScrollTaskUp(int) bool`, `ScrollTaskDown(int) bool`, `PageTaskUp() bool`, `PageTaskDown() bool`, and task-scroll touch/offset inspection needed by tests.
+- Closed lanes list owns `top/rows/total/fade`; open tree uses `Tasks.view` and its actual rendered row capacity.
+
+- [ ] Add `TestTaskViewportPagesAndKeepsSelectionVisible` with more tasks than pane rows; paging must change visible IDs and keep the selected ID visible.
+- [ ] Add `TestTaskScrollbarUsesViewportAndStopsBeforeComposer`; activate scrolling and prove no thumb occurs at or below `region.input.Y`.
+- [ ] Add `TestOpenTreePageScrollMovesVisibleTreeNotHiddenLanesList`; prove open-tree rows, not the hidden list, change.
+- [ ] Run these tests and observe failures from missing viewport APIs/current top truncation.
+- [ ] Add lanes task viewport state, clamping, selection-follow, visible-row click-region remapping, and viewport-derived scrollbar math.
+- [ ] Pass task-scroll APIs through rail and promote.
+- [ ] Add open-tree page/line scrolling over `Tasks.view`; preserve steer/wave replacement views and clone display state correctly.
+- [ ] Render the open-tree scrollbar only inside its pane columns above `InputFloor`.
+- [ ] Run `go test ./lanes ./rail ./promote ./tasks` and observe green.
+
+### Task 3: Centralize pane scrolling and add mouse-wheel routing
+
+**Covers:** chat-pane scrolling; keyboard focus routing; pointer-region routing; composer exclusion.
+
+**Files:**
+- Modify: `tui/cmd/rune-tui/main.go`
+- Modify: `tui/cmd/rune-tui/historydepth_test.go`
+- Create or Modify: `tui/cmd/rune-tui/scrollrouting_test.go`
+
+**Interfaces:**
+- Add one shell dispatcher that accepts target pane, direction, amount/page mode.
+- Add region hit-testing for `region.chat`, `region.tasks`, and `region.tasks.tree`.
+- Handle `tea.MouseWheelMsg` with a small fixed line step (3).
+
+- [ ] Add `TestPageKeysRouteByFocusedPane`: page keys alter only the focused pane; task focus must never alter chat offset.
+- [ ] Add `TestMouseWheelRoutesByCursorAndComposerOwnsNone`: wheel over chat/tasks changes only that pane; wheel over composer changes neither.
+- [ ] Add/retain a chat-backfill assertion proving upward exhaustion still grows bridge history depth.
+- [ ] Run the new tests and observe failure because task/page routing and wheel handling are absent.
+- [ ] Move page/control key handling ahead of composer editing but after modal/menu ownership; route by focus.
+- [ ] Add coordinate-based wheel dispatch; no-op outside pane regions and over composer.
+- [ ] Touch only the moved pane’s fade state; touch downward movement as well as upward movement.
+- [ ] Run `go test ./cmd/rune-tui -run 'Scroll|History|Wheel|PageKeys'` and observe green.
+
+### Task 4: Integrate, review, and release through #2535
+
+**Covers:** full fix-cycle evidence and delivery.
+
+**Files:**
+- Modify: `docs/architecture/boundary-law.md`
+- Modify: release/version files selected by the repository release policy.
+- Update: Gitea issue #2535, PR, and CI evidence.
+
+- [ ] Update the boundary law so the newer per-pane-scroll/composer-ownership contract supersedes obsolete composer-history wording everywhere.
+- [ ] Run `gofmt` on all changed Go files.
+- [ ] Run affected package suites: `go test ./lanes ./chatpane ./nav ./rail ./promote ./tasks`.
+- [ ] Run focused shell tests and compare PTY/live failures against the recorded baseline.
+- [ ] Run the repository canary/quality commands discovered in `AGENTS.md`, `Makefile`, and required Gitea checks.
+- [ ] Dispatch independent spec and code-quality reviews; repair only evidenced defects.
+- [ ] Create conventional commits referencing `#2535`, apply the release-policy semantic bump, push the issue branch, open a Gitea PR linked to `#2535`, and wait for required CI.
+- [ ] Merge only after local evidence and required checks pass; close #2535 with test, commit, PR, version, and deployment evidence.
+
+## Canary contracts approved by “fix it”
+
+1. **CHAT_FOCUS_SCROLL:** page/control keys move chat only and preserve deeper-history fetch.
+2. **TASK_FOCUS_SCROLL:** the same keys move the active task surface only, including the open task tree.
+3. **POINTER_PANE_SCROLL:** mouse wheel targets the pane beneath the pointer regardless of keyboard focus.
+4. **COMPOSER_NO_SCROLL:** composer wheel/page input changes no pane and Up/Down never recalls sent input.
+5. **TASK_VIEWPORT_TRUTH:** selected task remains visible; click regions map visible rows to absolute task IDs; thumb follows viewport, not merely selection.
+6. **SCROLLBAR_FLOOR:** no pane thumb appears in or below the composer region.
+7. **BORDER_ANSI_ISOLATION:** nested ANSI resets cannot change either border edge; intended unfocused grey remains intact.
+
+## Self-review
+
+- Coverage: all owner-reported symptoms and #2535 acceptance scope map to Tasks 1–3; delivery maps to Task 4.
+- Placeholders: none.
+- Type consistency: task-scroll method names remain identical across lanes → rail → promote → tasks → shell.
+- Scope guard: persisted input history may remain for compatibility, but has no UI navigation authority.
