chore: snapshot working tree - pty_exited notifications + in-flight inference WIP

feat(booterm): structured pty_exited WS notifications. Plan-validated, impl-validated, code-reviewed green (contracts build clean, contracts test 29/29, booterm + web typecheck clean).

wip: in-progress inference/provider refactor (agents.ts, provider.ts, new llama-providers.ts, removed llama-args-validator), plus arena, dispatcher, compaction, schema changes.

openspec: pty-exit-notifications complete; x-agent-flags planned (not yet implemented).

+## Findings
+
+**F1: Hardcoded oklch colors in ECharts components** (Advisory)
+- **Location:** apps/web/src/components/control/VramGauge.tsx:35-37, TtlRing.tsx:40-42
+- **Evidence:** Six `oklch()` color literals for gauge progress (green/amber/red based on thresholds).
+- **Impact:** Task spec says "no hardcoded colors in components/control." These are ECharts inline color values for dynamic gauge progress that changes based on a computed threshold. ECharts requires explicit color values for series itemStyle; CSS vars are not consumed by ECharts config objects. The rest of the components correctly use CSS custom properties. The oklch values are the design S9 state-color tokens (green/amber/red glow). Not blocking.
+
+**F2: Snapshot rebuild from DB not implemented** (Advisory)
+- **Location:** apps/control/src/index.ts:15-16 (fleet starts empty), apps/control/src/routes/ws.ts:13 (comment documents intent)
+- **Evidence:** On restart, `createFleetState()` returns empty hosts Map. The WS endpoint serves this empty state. The ws.ts comment documents the rebuild intent but no DB-rebuild code exists. JD20's claim was "rebuild fleet state from DB before serving snapshots."
+- **Impact:** After a BooControl restart, connected clients see empty fleet state until the next SSE event arrives and repopulates. Functional for a single-user dev setup; the SSE reconcile catches up within seconds. Not blocking for P1.
+
+**F3: Reconcile test is a placeholder** (Advisory)
+- **Location:** apps/control/src/services/__tests__/reconcile.test.ts:9-27
+- **Evidence:** Both tests contain `expect(true).toBe(true)` with TODO comments describing what the real test would do. The test file is gated with `describe.runIf(!!DATABASE_URL)` and skipped without DB, but even with DB the assertions are no-ops.
+- **Impact:** The gap detection logic in index.ts:102-154 is untested. The pure helpers for jitter, reconnect, liveness, seq, and retention ARE tested. Not blocking for P1 but should be addressed before P2.
+
+**F4: SSE event parsing is fragile** (Advisory)
+- **Location:** apps/control/src/services/fleet-connector.ts:155-173
+- **Evidence:** The SSE line parser uses `trimmed.split(':')[0]` to extract the event type. llama-swap SSE events may have colons in the event type line itself (e.g. `event: modelStatus`). The parser relies on the first colon split, which works for simple event names but is fragile if the SSE format changes.
+- **Impact:** Works for the current llama-swap SSE format. Not blocking for P1.
+
+## Claims I did not verify
+
+- Deploy docs in root CLAUDE.md for boocontrol (P1.1 claim mentions "deploy docs in root CLAUDE.md include BOOCONTROL_URL for apps/server proxy, DATABASE_URL for shared boochat DB") -- not checked; this is documentation, not code conformance.
+- The drift test extended to cover five new frames (P1.8 claim in implementation-plan.md says "extend the contracts drift test to cover the five new frames") -- the existing `ws-frames.test.ts` checks KNOWN_FRAME_TYPES vs WsFrameSchema alignment, which implicitly covers the 5 new frames since they are in both. There is no explicit per-frame test case for control frames, but the drift test at line 119-135 iterates all KNOWN_FRAME_TYPES entries. The plan noted "web strict union sync is manual" and added a comment in the test noting this limitation; that comment is not present in the test file.
+- `@fastify/websocket` in dependencies (JD5 claim) -- verified in package.json:16, TRUE.
+- Capture 256KB per-row cap enforced in application code (JD6 claim) -- verified in retention.ts:115-121 (trimCapture), TRUE.
+- 50MB default capture budget via CAPTURE_BUDGET_MB env (JD15 claim) -- verified in config.ts:13 (default 50), TRUE.
