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).

+
+Reviewed against SPEC.md R1–R8.
+
+## R1–R8 checklist
+
+| Req | Status | Notes |
+|-----|--------|-------|
+| R1 entrypoint | ✅ | argparse `--mode` required choices; `cmd_tick` returns `summary` dict, never raises; exits 0 on unknown loop |
+| R2 tick flow | ✅ | 11 steps match technical.md §7 precisely |
+| R3 daemon | ✅ | `cmd_daemon` loops on `cmd_tick` + `time.sleep`; KeyboardInterrupt = DAEMON_STOPPED; `--max-iterations` honored |
+| R4 harness substitution | ✅ | `_substitute` handles 7 tokens; missing tokens left literal; default command matches D8 (opencode) |
+| R5 context-floor guard | ✅ | `_context_floor_ok` before any Implement call; halts `human_intervention` on `loop_mode_eligible=False`; best-effort allows tick if vram_detect itself unavailable |
+| R6 idempotence | ✅ | state writes only after verdict parse + orchestrator both succeed; pre-step-10 crashes leave `.state.loop` untouched |
+| R7 tests | ✅ | 18 tests, 7 classes; all subprocess stubbed |
+| R8 out-of-scope | ✅ | audit/backlog/worktree-creation/prompts deferred to tasks 4–7 |
+
+## Edge cases checked
+
+1. **Subprocess failure in `--check-gate`** — `_run_json` returns `None`, `cmd_tick` skips with `gate_subprocess_failed`. No crash. ✅
+2. **Subprocess failure in `vram_detect --loop-mode`** — best-effort allows tick (avoids a broken vram_detect tool from halting every loop on a platform where it isn't installed). ✅
+3. **Empty verifier stdout** — `parse_verdict` returns `None`; `cmd_tick` halts `verifier_failed` without advancing state. ✅
+4. **Fenced JSON verdict** — handled by `_FENCE_RE` regex, tries fenced body before raw text. ✅
+5. **Line-commented JSON verdict** — stripped by `_strip_comments`. ✅
+6. **Missing `pass` key** — `parse_verdict` requires it; returns `None`. ✅
+7. **Score history shorter than window** — no capping until length > window; oldest dropped. ✅
+8. **No roles configured in loop.json** — `_role_prompt` returns `None or ""`; harness gets empty prompt-path token. User's config responsibility; runtime refuses on empty cwd (Path resolve) if `_find_project_dir` fails. ✅
+9. **Worktree declared but missing** — runner uses `project_root` as cwd and logs nothing (per R8 deferred to task 5). ✅
+10. **`KeyboardInterrupt` mid-tick** — bubbles up; no state write happens; next tick starts fresh. ✅
+11. **`KeyboardInterrupt` in daemon mode** — `_append_tick_log(DAEMON_STOPPED)` then exit 0. ✅
+
+## Code-quality observations
+
+1. **`_run_json` parses the last stdout line only** — correct for `--check-gate --json` (last-line contract per AGENTS.md), but assumes the harness never emits JSON mid-session. For the harness-substitution roles (Implement/Verify/Orchestrate), the runner captures full stdout (not `_run_json`), so the constraint only applies to `--check-gate` and `vram_detect --loop-mode`. Safe.
+2. **Token substitution is string-only** — `{verdict}` gets `json.dumps(verdict)`. Not shell-escaped. The harness command is parsed with `shlex` by opencode's own runner; subprocess.run with list argv means no shell injection. Safe as long as `harness.command` stays list-typed (it does — the cfg loader rejects non-list commands via the `if not command: command = [...default...]` fallback). ✅
+3. **No timeout on harness invocations** — explicitly per SPEC ("v1 has no timeout; harness owns its timeout policy"). Fine. Worth revisiting if a loop's harness hangs and the OS unit keeps scheduling — but the scheduler interval provides natural rate-limiting.
+4. **`_invoke_harness` passes `cwd=cwd` to `subprocess.run`** — if `cwd` doesn't exist, `subprocess.run` raises `FileNotFoundError`. Caught by the outer `except (OSError, subprocess.SubprocessError)` which emits stderr and returns empty — fine. ✅
+5. **`_read_state_loop` swallows `JSONDecodeError`** — returns None. Caller treats as `untracked`. A corrupt `.state.loop` becomes an untracked loop. Acceptable for v1; `--audit` flags untracked. ✅
+6. **`_write_state_loop` uses `tmp.replace(f)` atomic write** — same pattern as `status.py`; crash-safe. ✅
+
+## Verdict

+APPROVE. Ready for bug_find.
