+Research round for #245 (4-phase, agent-generated, filed by research stage per #204; comment on the issue is the research-clear trigger)
+
+---
+
+I'll start by searching for a matching skill, and in parallel take a first look at the repository layout so the INWARD phase has ground truth.
+
+No exact skill match — the candidates are generic research workflows, and this task has its own governed 4-phase contract that supersedes them. I'll proceed with the prompt's own workflow. Now, INWARD: mapping the codebase first.
+
+The repo is the Rune project with a Textual-based TUI. There's already a `research/issue-245-research.md` — I must inspect it before overwriting, plus the governing workflow and umbrella config.
+
+The existing file is the prior round's output (merged via PR #250 per git log) — this run is the E2E acceptance re-run, and the stage's contract is to overwrite it with a fresh round. I'll do the research genuinely this run rather than copying: verify every inward claim against current code, and fetch live sources myself.
+
+Confirmed the reactive inventory at `src/rune/rune_tui.py:1520-1527` and the pin `textual==8.2.8` (tests/test_check_dep_lock.py:27). Notably, the repo's own skill base (`src/rune/skills/textual-craft/knowledge.md:30-31`) already prescribes `var()`/`set_reactive()` — I'll verify whether the TUI follows it. Now reading the exact call sites.
+
+Call sites confirmed with current line numbers (several shifted vs. the prior round — verification was worthwhile). Now mapping the remaining fan-out sites, `planning_active` flips, and the canary's introspection.
+
+All reactive assignment/fan-out sites are now mapped — including two the prior round missed (`_update_status()` after `mode` flips at 2137-2144 and `self.model` loads at 1008-1009, 629). A few last inward reads, then OUTWARD.
+
+INWARD is complete and verified against current code. Before OUTWARD, one quick read of the artifact gate contract (`scripts/research_artifact.py`) so the output formatting matches what CI actually checks, then I'll fetch the live sources in parallel.
+
+Three sources retrieved live (reactivity guide, changelog — confirming 8.2.8 is current with the GC/`Widget.BLANK`/scroll fixes — and RichLog reference). The Textualize `textual-speedups` URL 404s this run, so I'll fetch the maintainer's repo as substitute, plus the Widget API for `anchor()` — which the 4.0.0/8.2.4 changelog entries suggest is the sanctioned fix for the prune-and-scroll risk in the bounded-log candidate.
+
+The speedups README confirms the "possibly imperceptible" caveat verbatim, and the changelog gives me two more load-bearing facts: `remove_children` layout fix (6.6.0, #6206) and `Widget.anchor` semantics (4.0.0, #5950) — both directly shape the bounded-log build instructions. Two final inward reads: how WorkPane implements its bounded pruning (the pattern to mirror) and the mode-flip sites that couple `_update_status` with pane visibility.
+
+Two line sites (629, 1008-1010) need class context before I cite them. Quick reads, then I write the deliverable.
+
+All evidence is in hand. Now writing the deliverable file with the exact gate-required format.
+
+File written. Running a gate self-check: exact phase markers, evidence regexes (≥2 code paths, ≥2 unique-domain URLs), and the required header line.
+
+`## INWARD` has markdown prefixes — if the gate regex keys on bare tokens, that fails. Let me check the actual gate regex before adjusting.
+
+The gate uses word-boundary regex (`\bINWARD\b`), so `## INWARD` passes — but the evidence checks around line 220-260 need a closer look, especially the dead-link detection that might flag the 404 URL I mention.
+
+The gate does more than the prompt said — it live-fetches every OUTWARD URL (my disclosed 404 link would fail verification), requires the INNOVATION section to re-reference an OUTWARD URL, and requires a sufficiency statement, a "kill test" (with a space — `kill_test` won't match), and a `plans/` artifact path in SYNTHESIS. Let me simulate the full gate against my file to find every gap before fixing.
+
+Variable shadowing bug in my simulation — fixing and rerunning.
+
+Simulation confirms 4 fixable gaps: the dead URL would fail live-fetch, INNOVATION has no source-tied URL, and SYNTHESIS lacks the sufficiency marker, a space-separated "kill test", and a `plans/` artifact reference. Applying surgical fixes.
+
+Gate simulation passes on every check. Marking the task complete and reading the final file to reproduce it verbatim as my final message.
+
+The round is complete: written to `research/issue-245-research.md` (verified against the actual `pipeline-gate.yml` evidence checks — phases, 8 inward citations, 4 live-annotated URLs across 3 unique domains, source-tied INNOVATION, qualified SYNTHESIS with kill test and `plans/` artifact), and nothing was committed or pushed. Note: this is the E2E acceptance re-run — the file previously held round 1 (merged via PR #250); per the stage contract it has been overwritten with this fresh round, which independently re-verified every claim against current code (several line numbers had drifted) and re-fetched all sources live. Here is the same content as my final message:
+
+Research round for #245 — E2E acceptance: research round on Textual 8.x reactive performance patterns (4-phase, agent-generated)
+
+ISSUE: Disposable acceptance issue for the Forge Cognitive Research Loop (P0.8).
+Topic: Textual 8.x reactive performance patterns as applied to the Rune TUI.
+Repo pin: `textual==8.2.8` (requirements-ci.txt:105, pyproject.toml:12). The upstream CHANGELOG fetched this run lists 8.2.8 (2026-06-30) as the newest release — the codebase is on the current stable.
+
+## INWARD
+
+The TUI surface lives in `src/rune/rune_tui.py`, `src/rune/chat_bubble.py`, `src/rune/message_widgets.py` (governed: every TUI surface registered per AGENTS.md:27, rune modules need tests or a canary per AGENTS.md:28, rune_tui.py is mapped to the `orchestration` umbrella in config/umbrellas.json:161 with canary gates at config/umbrellas.json:198-206).
+
+Reactive inventory — RuneApp class-level reactives (src/rune/rune_tui.py:1520-1527), verified this run:
+
+| Reactive | Line | Visual? | Watcher? |
+|---|---|---|---|
+| `mode` | rune_tui.py:1520 | yes (StatusBar) | none defined |
+| `project` | rune_tui.py:1521 | yes (StatusBar) | none |
+| `model` | rune_tui.py:1522 | yes (StatusBar) | none |
+| `task_width` | rune_tui.py:1523 | yes (pane split) | none |
+| `_last_ctrl_c` | rune_tui.py:1524 | no | none |
+| `planning_active` | rune_tui.py:1525 | no | none |
+| `plan_threshold` | rune_tui.py:1526 | no | none |
+| `work_pane_visible` | rune_tui.py:1527 | yes (pane display) | none |
+
+Key findings:
+
+1. **No `watch_*` or `validate_*` methods exist anywhere in the TUI** (grep across src/rune/rune_tui.py, src/rune/chat_bubble.py, src/rune/message_widgets.py: zero matches). Propagation is manual imperative fan-out after each assignment:
+   - `action_resize_left/right` clamp + set `self.task_width` (rune_tui.py:4043, 4048) then call `_apply_resize()` (rune_tui.py:4044, 4049) which mutates `task.styles.width`/`chat.styles.width` (rune_tui.py:4051-4059). The reactive assignment *also* triggers Textual's smart refresh (S1). Two refresh paths per keypress, one of them App-level for a change only two children care about. Clamping lives at the call-site instead of a validator.
+   - `action_toggle_work_pane` sets `self.work_pane_visible` (rune_tui.py:4030) then calls `_apply_work_pane_visibility()` (rune_tui.py:4031, 4033-4039); the same helper is also invoked from `on_mount` (rune_tui.py:1581) and after mode flips (rune_tui.py:3998, 4007).
+   - `_update_status()` (rune_tui.py:4061-4066) copies `mode`/`model`/`project` into the StatusBar's plain mirror attributes — and it is called manually after every assignment: rune_tui.py:2041, 2101, 2144, 2318, 2376, 2382, 2462, 2467, 2881, 3997, 4006. StatusBar itself re-declares plain (non-reactive) `mode`/`model`/`project` in its `__init__` (rune_tui.py:1006-1015) — state duplication with hand-rolled fan-out (the mirror at rune_tui.py:629 is `ModelItem.model`, a different class, not a reactive site).
+2. **Non-visual state declared as `reactive()`**: `_last_ctrl_c` (assigned at rune_tui.py:3980, 3988), `planning_active` (flipped per message cycle at rune_tui.py:2039, 2099; read at 2236), `plan_threshold` — none affect rendering, yet every assignment engages App-level refresh machinery.
+3. **Unbounded chat-log widget growth**: `ChannelView.add_message` (rune_tui.py:1198-1210) mounts a `MessageBox` (src/rune/chat_bubble.py:279, a `Horizontal` wrapping `ChatBubble(Static)`) into `VerticalScroll` per message and calls `scroll_end` — no cap. Contrast: `WorkPane` is bounded at `_WORK_PANE_MAX_ENTRIES = 120` with oldest-entry eviction in `add_object` (rune_tui.py:1215, 1309-1325), and RichLog (used for command results, rune_tui.py:552) supports upstream `max_lines`. A long session accumulates thousands of mounted widgets; Textual's own history shows large scrollable containers were a real perf hazard (S2 #6317). The `self.messages` projection list (rune_tui.py:1208-1210) is the durable display record; durable state lives in ConversationStateRepository, so only DOM widgets are safe to bound.
+4. **Pre-mount reactive assignment**: `RuneApp.__init__` does `self.model = saved` (rune_tui.py:1538-1541) — with no watchers this is harmless today, but it invokes full reactive machinery pre-mount and becomes load-bearing once watchers are added (S1: use `set_reactive()` in constructors; the repo's own skill base agrees — src/rune/skills/textual-craft/knowledge.md:30-31 prescribes `var()` for non-visual state and `set_reactive()` in constructors; the TUI currently follows neither).
+5. **Existing contracts this touches**:
+   - tests/test_message_widgets.py:1-29 covers `ToolCallWidget`/`ChatBubble` behavior (no app-mount harness yet); tests/test_version_footer.py:23 imports `textual.widgets.Static`; tests/test_tui_validator_imports.py:71 shows the repo's textual-import-guard style tests must use.
+   - tests/test_check_dep_lock.py:27,63 pin `textual==8.2.8` — dependency changes are gated, so "don't bump the pin" is also the cheap path.
+   - `src/rune/canary_tui_drift.py` is the TUI-wiring canary; verified it introspects memory_store/warm_router/memory_consolidation via `inspect.getsource` (canary_tui_drift.py:42, 119, 131, 142) — it does NOT introspect rune_tui.py, so reactive changes don't need canary source-pattern updates.
+   - `scripts/research_artifact.py:30-45, 48-73` is the schema gate this round's evidence format feeds.
+
+INWARD claim IDs (for causal links):
+- **I1**: 3 of 8 RuneApp reactives are non-visual and needlessly engage refresh machinery on hot paths (rune_tui.py:1524-1526, 2039, 2099, 3980).
+- **I2**: Reactive changes are propagated by manual imperative calls, not watch methods, causing double refresh paths and 11 scattered `_update_status()` call-sites (rune_tui.py:4043-4066 and grep list above).
+- **I3**: Chat message widgets grow unbounded while WorkPane and RichLog demonstrate the bounded pattern exists in-repo and upstream (rune_tui.py:1198, 1215, 1309-1325, 552).

+## OUTWARD
+
+Live sources retrieved this run (tool = webfetch over HTTPS; every URL below was actually fetched):
+
+- **S1** — Textual Reactivity guide (current docs): https://textual.textualize.io/guide/reactivity/
+  - learned: smart refresh coalesces multiple reactive changes into one refresh; assigning an unchanged value does NOT refresh; `var()` gives reactive superpowers with no refresh/layout; `watch_<name>` fires only on real change (unless `always_update=True`); `validate_<name>` is the sanctioned place for clamping; `set_reactive()` exists precisely for constructor-time assignment because watchers that query the DOM may break pre-mount; `recompose=True` is "slightly less efficient than a simple refresh, and best avoided if you need to update rapidly or you have many child widgets"; compute methods re-run when ANY reactive on the object changes — keep them cheap.
+- **S2** — Textual CHANGELOG (main branch, 8.2.8 back to 4.0.0): https://raw.githubusercontent.com/Textualize/textual/main/CHANGELOG.md
+  - learned (performance-relevant): 8.2.8 is the latest release (2026-06-30); 8.1.0 replaced DOM circular references with weak references to improve GC times (#6410); 8.0.1 tweaked GC to reduce gc time (#6402); 8.2.3 moved resize handling to a timer to reduce window-resize lag (#6471); 8.2.2 removed pointless style updates when resizing (#6464); 7.1.0 added `Widget.BLANK` to optimize rendering of large scrolling containers; 7.0.3 fixed a performance issue with large scrollable containers (#6317); 6.6.0 fixed `remove_children` not refreshing layout (#6206); 4.0.0 redefined `Widget.anchor` to anchor scroll position to the bottom of a container (#5950); 5.0.0 made textual-speedups auto-import when installed (`TEXTUAL_SPEEDUPS=0` disables).
+- **S3** — textual-speedups README: https://github.com/willmcgugan/textual-speedups
+  - NOTE: the canonical org-hosted URL (Textualize org, textual-speedups repo) returned HTTP 404 this run — substituted with the maintainer's personal repo above (the changelog S2 links the speedups library by maintainer). learned: optional Rust accelerators for `Offset`/`Size`/`Region`/`Spacing` geometry math; auto-imported by Textual ≥5.0.0 when installed; the README itself warns "unless your Textual app is particularly complex, you might not even notice a difference!" and says a benchmark tool doesn't exist yet.
+- **S4** — RichLog widget reference: https://textual.textualize.io/widgets/rich_log/
+  - learned: `max_lines` (a `var`) bounds retained lines; `write()` defers rendering until size is known; `auto_scroll` is a var; the simpler `Log` widget is recommended for plain text. Confirms bounded retention is a first-class upstream idiom.

+Search queries recorded: "Textual 8.x reactive performance patterns", "textual changelog 8.x performance GC scrollable containers", "textual-speedups repository", "RichLog max_lines widget reference", "Textual Widget anchor API".
+
+OUTWARD claims (IDs for causal links):
+- **O1** (S1): `var()` is the sanctioned way to hold non-visual reactive state at zero refresh cost; watch/validate methods are the sanctioned way to propagate and clamp reactive state; `set_reactive()` is the sanctioned constructor pattern — supporting I1 and I2.
+- **O2** (S2): Textual 8.2.8 already banks the major framework-side performance work (weak-ref GC, large-container fix, Widget.BLANK, resize de-lag) — framework-level wins are already had at our pin; remaining wins are application-level. Also: `remove_children` layout-refresh and bottom-`anchor` semantics are the upstream primitives a bounded chat log should use.
+- **O3** (S3): The only extra framework accelerator (textual-speedups) is optional, geometry-only, benchmark-less, and self-described as possibly imperceptible — weak candidate under our contract-gated dep lock (tests/test_check_dep_lock.py).
+- **O4** (S4): Bounded log retention (`max_lines`-style) is a first-class widget idiom — supporting I3.
+
+Answer to the driving question "is there anything BETTER than the obvious approach?": **No framework-level mechanism beats the obvious ones.** 8.2.8 already includes the GC/layout/container work; the leverage is in how RuneApp *uses* reactives (var vs reactive, watchers vs manual fan-out, bounded widget population). The one genuinely better-than-obvious find is `validate_task_width` (S1) — clamping belongs in the reactive validator, not the two action methods.
+
+## INNOVATION
+
+Candidates, each evaluated for effort / risk / fit:
+
+- **C1 — Convert non-visual reactives to `var()`.**
+  derived_from: [I1, O1]
+  proposal: in src/rune/rune_tui.py:1524-1526, change `_last_ctrl_c`, `planning_active`, `plan_threshold` from `reactive(...)` to `var(...)` (import `var` alongside `reactive` at rune_tui.py:108). Watchers/validation semantics are preserved; refresh machinery is no longer engaged — mechanism per S1: https://textual.textualize.io/guide/reactivity/ ("If you *don't* want an attribute to prompt a refresh or layout but you still want other reactive superpowers, you can use var").
+  expected_gain: removes App-level refresh on every planning-state flip and every Ctrl+C timestamp update — the hottest assignment paths in the app (rune_tui.py:2039, 2099, 3980, 3988).
+  effort: trivial (~4 lines). risk: negligible — nothing renders from these three. fit: exact match to documented upstream idiom (S1) AND the repo's own textual-craft checklist (knowledge.md:30). **ADOPT.**
+
+- **C2 — Replace manual fan-out with watch methods (and clamping with a validator).**
+  derived_from: [I2, O1, O2]
+  proposal: add `watch_task_width` (body = current `_apply_resize`), `watch_work_pane_visible` (body = current `_apply_work_pane_visibility`), and `watch_mode`/`watch_model`/`watch_project` (body = `_update_status`, kept as shared helper) in RuneApp. Add `validate_task_width` clamping to [20, 80] (S1 validation pattern) and delete the clamp from the two action methods (rune_tui.py:4043, 4048). Delete the now-redundant explicit `_apply_resize()`/`_apply_work_pane_visibility()`/`_update_status()` call-sites at rune_tui.py:2041, 2101, 2144, 2318, 2376, 2382, 2462, 2467, 2881, 3997, 4006, 4031, 4044, 4049 — BUT keep `_apply_work_pane_visibility()` invoked from `on_mount` (rune_tui.py:1581) and after mode flips (3998, 4007), because pane visibility depends on BOTH `work_pane_visible` and `mode`; make `watch_mode` call `_apply_work_pane_visibility()` too so 3998/4007 can go. In `RuneApp.__init__`, replace `self.model = saved` (rune_tui.py:1541) with `self.set_reactive(RuneApp.model, saved)` (S1 constructor guidance). Watcher bodies keep the existing try/except guards (they query the DOM; guards make them safe even if a watcher fires pre-mount).
+  expected_gain: single refresh path per change; eliminates App-level refresh where a two-child update suffices; 11 scattered call-sites collapse into 5 declarative watchers; aligns with upstream idiom so future Textual refresh optimizations apply automatically.
+  effort: small (~40 lines, behavior-preserving). risk: low — the only pre-mount assignment (1541) is handled with `set_reactive`; `_update_status` is None-guarded (rune_tui.py:4063) so worst case is a silent no-op, verified against `on_mount` wiring at rune_tui.py:1580. fit: high. **ADOPT.**
+
+- **C3 — Bound chat-log widget population.**
+  derived_from: [I3, O2, O4]
+  proposal: add `_CHAT_LOG_MAX_WIDGETS = 200` beside `_WORK_PANE_MAX_ENTRIES` (rune_tui.py:1215). In `ChannelView.add_message` (rune_tui.py:1198-1210), after `log.mount(bubble)`, prune the oldest mounted `MessageBox` children beyond the cap: batch-remove `log.children[:overflow]` via `remove_children` (layout-refreshing since 6.6.0, S2 #6206), preserving `scroll_end(animate=False)`. Never touch `self.messages` — the projection list and ConversationStateRepository remain the durable record; only DOM widgets are bounded. Do NOT rewrite the log on RichLog/Line-API virtual rendering (RichLog's `max_lines` idiom — https://textual.textualize.io/widgets/rich_log/ — proves bounded retention is upstream-sanctioned, but its lines are not interactive widgets): bubbles must stay interactive (ThinkingBubble toggle chat_bubble.py:261-276; ToolCallWidget decision buttons message_widgets.py:14-41). Scroll-jump caveat: pruning while the user has scrolled up will move the view; acceptable at cap events (2-per-100-messages), and `Widget.anchor` (S2 #5950) is the upstream primitive if follow-up polish is ever needed.
+  expected_gain: prevents multi-thousand-widget DOM in long sessions — the single largest real-world scroll/refresh latency factor for this app per S2's large-container history (#6317) and per WorkPane's existing bounded design (rune_tui.py:1309-1325, quality I-3 discharge).
+  effort: medium (~25 lines + tests). risk: low-medium — prune only DOM children; verify scroll behavior in the Pilot test. fit: high. **ADOPT.**
+
+- **C4 — Add `textual-speedups` dependency.**
+  derived_from: [O3] — **REJECTED.** Gain unquantified (upstream README admits no benchmark exists) and self-described as possibly imperceptible; adds a native wheel to a contract-gated lock (tests/test_check_dep_lock.py:27,63); auto-import (S2 5.0.0) means users who install it already get it for free. Honesty over novelty: no measured problem it solves here.
+
+- **C5 — Rewrite chat log on RichLog / Line API for virtual rendering.**
+  derived_from: [I3, S4] — **REJECTED:** loses interactive per-message widgets (collapse/expand, tool decision buttons — message_widgets.py:14-41); C3 captures the win at far lower risk.
+
+Adopted set: C1 + C2 + C3. Every adopted candidate derives from OUTWARD evidence (C1←O1, C2←O1/O2, C3←O2/O4), satisfying the causality contract of scripts/research_artifact.py:48-73.
+
+## SYNTHESIS
+
+Decision: **PROCEED.** Adopt reactive hygiene (C1, C2) and bounded chat-log population (C3); reject framework additions (C4, C5).
+evidence_used: [I1, I2, I3, O1, O2, O3, O4]
+Evidence sufficiency: SUFFICIENT to design from — S1 (https://textual.textualize.io/guide/reactivity/) and S2 (https://raw.githubusercontent.com/Textualize/textual/main/CHANGELOG.md) independently converge on the same mechanisms (var / watch / validate / set_reactive / bounded retention), corroborated by the repo's own textual-craft checklist (src/rune/skills/textual-craft/knowledge.md:30-31); no unresolved unknowns gate the design.
+sources_used: S1 (https://textual.textualize.io/guide/reactivity/), S2 (https://raw.githubusercontent.com/Textualize/textual/main/CHANGELOG.md), S4 (https://textual.textualize.io/widgets/rich_log/), code paths src/rune/rune_tui.py, src/rune/chat_bubble.py.
+blocking_unknowns: none blocking. (Non-blocking: micro-benchmark deltas for C1/C2 are expected small; C3's win is structural. If a number is wanted, a before/after widget-count assertion in the Pilot test is the cheap proxy.)
+Kill test (cheapest disproof): if adding `watch_task_width`/`watch_model` changes observable behavior (status bar or pane split regress on startup or mode flips), that disproves the watcher conversion — fall back to keeping the manual calls AND make the three non-visual reactives `var()` per C1; the round still delivers value. Behavior risk is bounded because `_update_status` (rune_tui.py:4063) and `_apply_work_pane_visibility` (rune_tui.py:4035-4039) are already exception-guarded.
+feasibility: high — all changes confined to src/rune/rune_tui.py plus one new test file. No dependency changes (C4 rejected), no schema changes, no canary source-pattern updates (canary_tui_drift.py does not introspect rune_tui.py — verified canary_tui_drift.py:42,119,131,142).
+
+### BUILD INSTRUCTIONS (ordered, self-contained for the implementer)
+
+0. Plan artifact first: create plans/245-reactive-hygiene.md (henxel: "Plans are markdown, one per build (in ./plans)") recording the adopted set (C1-C3), the red-first test list from step 2, and the gates from step 4 — the synthesis commits to this artifact as the implementable plan.
+
+1. Branch `perf/245-reactive-hygiene` off master. Do NOT bump the textual pin — 8.2.8 already contains the framework-side work (O2, tests/test_check_dep_lock.py:27).
+
+2. RED-FIRST tests — write before touching source (bug-fix discharge contract, AGENTS.md:53-60; all must fail on current code):
+   a. New file tests/test_rune_tui_reactive.py. Guard the textual import at module top in the style of tests/test_tui_validator_imports.py:71 (textual/textual_autocomplete/rich availability), since CI aborts on unguarded textual imports (tests/test_orchestration_canary.py:27).
+   b. test_non_visual_state_is_var: assert `_last_ctrl_c`, `planning_active`, `plan_threshold` on RuneApp are `textual.reactive.var` instances, and `mode`/`model`/`project`/`task_width`/`work_pane_visible` remain `reactive`. RED on current code.
+   c. test_validate_task_width_clamps: set `app.task_width = 999` under `App.run_test()`; assert it clamps to 80 (and 10 → 20). RED.
+   d. test_watch_methods_propagate: under `run_test()`, set `app.task_width = 65` and assert `#task-channel` styles width is "65%" and `#chat-channel` is "35%" WITHOUT `_apply_resize` being called (monkeypatch it to raise). Set `app.model = "x"` and assert StatusBar reflects it without `_update_status()` being invoked. RED on current code.
+   e. test_status_and_pane_track_mode_flip: flip `app.mode = "task"` and assert `_apply_work_pane_visibility` was NOT called manually yet the pane display matches `_work_pane_visible_for("task")`. RED.
+   f. test_chat_log_bounded: under `run_test()`, push 220 messages via `chat_channel.add_message(...)`; assert `len(log.children) <= 200` while `len(chat_channel.messages) == 220` (projection survives pruning). RED.
+
+3. Implement (src/rune/rune_tui.py only):
+   - Step 1 (C1): line 108 import gains `var`; rune_tui.py:1524-1526 become `var(0.0)`, `var(False)`, `var(0)`. Keep trailing comments.
+   - Step 2 (C2): convert `_apply_resize` body (4051-4059) into `watch_task_width(self, width)`; add `validate_task_width` clamping to [20, 80] (S1); convert `_apply_work_pane_visibility` (4033-4039) into `watch_work_pane_visible` plus keep the helper for mode-driven calls; make `watch_mode` = `_update_status()` + `_apply_work_pane_visibility()`; add `watch_model`/`watch_project` = `_update_status()`. Delete redundant call-sites at 2041, 2101, 2144, 2318, 2376, 2382, 2462, 2467, 2881, 3997, 4006, 4031, 4044, 4049 and the clamp in 4043/4048. Keep `on_mount`'s `_apply_work_pane_visibility()` (1581). In `__init__` replace `self.model = saved` (1541) with `self.set_reactive(RuneApp.model, saved)`.
+   - Step 3 (C3): add `_CHAT_LOG_MAX_WIDGETS = 200` at rune_tui.py:1215-adjacent. In `add_message` (1198-1210) after `log.mount(bubble)`: compute `overflow = len(log.children) - _CHAT_LOG_MAX_WIDGETS`; if positive, `log.remove_children(*log.children[:overflow])` (batch removal refreshes layout per S2 #6206; fall back to per-child `.remove()` if the signature differs at the pin), then `log.scroll_end(animate=False)` as today. Never touch `self.messages`.
+   - Step 4: no canary changes (canary_tui_drift.py does not introspect rune_tui.py — verified this run). Run `henxels explain src/rune/rune_tui.py` before committing in case file-level rules changed.
+
+4. Gates that apply:
+   - Full suite + ruff + pyright ratchet + canaries + henxels re-entry (AGENTS.md:56-58).
+   - Umbrella propagation: rune_tui.py sits in the `orchestration` umbrella (config/umbrellas.json:161) whose canaries (config/umbrellas.json:198-206) are required gates; run scripts/umbrella_impact.py; add no phantom entries.
+   - research/pipeline gate: the build PR references #245 and this file (research/issue-245-research.md).
+   - dep lock: untouched (C4 rejected).
+
+5. PR strategy: one PR, title `perf(tui): reactive hygiene + bounded chat log (#245)`, body citing research/issue-245-research.md, the three adopted candidates (C1-C3) and two rejections (C4-C5) with reasons. Single reviewable commit-set; no release-bump beyond the repo's auto-version policy for src changes.
+
+6. Verification: run the new test file plus `pytest tests/test_message_widgets.py tests/test_version_footer.py tests/test_check_dep_lock.py`; then a manual `python -m src.rune` smoke (bubble render, Ctrl+1/2/3 mode flips, Ctrl+left/right resize, /model /project /mode commands, work-pane toggle) confirming no visual regressions.
