Restore archived tasks, fix dashboard scroll-reset, bind ornith, add Playwright smoke test

- **Restore 82 completed tasks** from tasks/complete/ back to tasks/ top
  level (all <7 days old per the cleanup policy; premature bulk archive
  was fixed).
- **Dashboard: fix scroll-reset on auto-refresh** — renderBoard rebuilds
  the board via innerHTML every 2s, destroying each column-body's
  scrollTop. Now snapshots column-body scrollTop + board.scrollLeft +
  view.scrollTop before rebuild and restores after (matched by
  PHASE_GROUPS index).
- **Dashboard UI additions** (pre-existing unstaged work): approval
  section cards, transition buttons, inline artifact editor (textarea for
  writing missing SPEC/VERDICT/etc from the detail modal).
- **Bind ornith as Implement model** — config.md: Model explicit to
  omlx/Ornith-1.0-35B-4bit-mlx, context window 32768. Interactive
  autopilot already used ornith via opencode default; now explicit.
- **Fix cleanup stub** — automaton-cleanup.sh had a stale --project arg
  pointing at a pytest temp dir (test isolation leak). Rewired to point
  at ~/.automaton.
- **Fix plist-isolation test** — test asserted host plist doesn't exist,
  but a real install creates it. Now snapshots mtime before run, asserts
  unchanged after (only a write during the test counts as bleed).
- **New Playwright smoke test** (tests/test_dashboard_ui.py) — 2 tests:
  board renders tasks, column scroll survives auto-refresh tick.
  Verified the test fails without the scroll fix (scrollTop resets to 0).
  Skipped via importorskip when playwright is absent (main CI stays
  green).
- **Clarify SI loop scope in README** — new-project onboarding section
  documents the framework-scoped self-improvement loop and options
  (leave/pause/create project loop).
- **CHANGELOG** documents all changes including the known model-divergence
  gap (mde tasks marked complete but per-role model binding was never
  implemented).

+# Doc Review: fix-context-sizing
+
+## Status: PASS
+
+## Docs Updated
+1. `config.md` — added `## Loop Role Models` section between System Requirements and Framework Version.
+2. `prompts/decompose.md` — added `**4k VRAM**` row in peak-context Guideline and `(4k VRAM)` rows in Sub-Task Size Targets; added `≤ 16k VRAM: REFUSE` line as a non-negotiable floor.
+3. `tasks/fix-context-sizing/SPEC.md` SPEC.md, IMPLEMENTATION.md — present in task folder.
+4. `tests/test_context_sizing.py` — 15 new test cases.
+
+## Documentation Gaps Closed
+- Loop role contract now exists in user-facing `config.md` (was previously implicit / absent).
+- `decompose.md`'s context budget guidance now exposes the 4k tier and refuses ≤16k budgets explicitly, so users decomposing tasks for small models can plan correctly.
+- `--loop-mode` CLI flag is documented in script's `--help` output.
+- JSON output schema now carries `available_context_kb` and `loop_mode_eligible` which downstream consumers (loop runner) can rely on.
+
+## Gaps Remaining (out of scope — deferred to Tier 2 per D17)
+- `README.md` does not yet document `--loop-mode` in the human-facing CLI section (Tier 2 task).
+- Dashboard does not surface `loop_mode_eligible` (v1.1 panel).
+- `prompts/decompose.md` line 135 still says "If model detection fails, use 128k tokens as default" — the auto-detection flow's fallback.  This is the user-facing decompose prompt's narrative; changing it would alter how decomposition agents behave in the research phase. Left intact; loop runner uses `--loop-mode` instead which *refuses* on this condition.
+
+## Cross-References
+- DESIGN.md not produced — task went directly research → implement per locked plan (Tier 1 fixes don't warrant a separate design phase).
+- This DOC_REVIEW covers the doc-side of the task; referee step is final.
+
+## Verdict
+Documentation is consistent with SPEC. No blocking gaps.
