fix: address PR review comments (round 2)

Human reviewer (zmanian):
- H1: Accept configurable embedding dimension in LanceDbVectorStore::new()
  instead of hardcoding 1536. Dimension is sourced from
  EmbeddingProvider::dimension() at init time.
- H2: Skip double-write of embeddings to DB when external vector store
  is active (pass None to insert_chunk for embedding column).
- H3: Update PR title from "refactor" to "feat" (net-new feature).
- H4: Document non-atomic update_embedding in struct doc comment.

Bot reviewer (Copilot):
- Cache LanceDB table handle via tokio::sync::OnceCell (avoid
  open_table per operation).
- Cache Arc<Schema> in struct (avoid rebuilding per insert).
- Fix error variants: ChunkingFailed → EmbeddingFailed for LanceDB
  store/delete operations.
- Propagate store_embedding errors in reindex_document instead of
  warn-only (prevents silent data loss).
- Prefetch document metadata map in backfill_embeddings to avoid N+1
  queries.
- Add lancedb feature + protoc to CI test matrix so LanceDB tests
  actually run on Linux.

+# Code Coverage Workflow
+#
+# This workflow runs test coverage analysis and uploads reports to Codecov.
+# Coverage reports help identify untested code paths and maintain code quality.
+#
+# What it does:
+# - Runs unit and integration tests with coverage instrumentation
+# - Runs E2E tests with coverage instrumentation
+# - Uploads coverage reports to Codecov (https://codecov.io/gh/nearai/ironclaw)
+#
+# Viewing coverage reports:
+# - PRs automatically get coverage comments showing changes in coverage
+# - Visit https://codecov.io/gh/nearai/ironclaw for detailed coverage reports
+# - Coverage reports are generated for three configurations:
+#   1. all-features: Full feature set
+#   2. default: Default features
+#   3. libsql-only: Minimal libSQL-only configuration
+# - E2E coverage tracks end-to-end test coverage separately
+#
+# Coverage files:
+# - Unit/integration: lcov.info (uploaded to Codecov with "unit" flag)
+# - E2E: e2e-coverage.info (uploaded to Codecov with "e2e" flag)
+#
+# Requirements:
+# - Uses cargo-llvm-cov for coverage instrumentation
+# - Requires PostgreSQL for integration tests (pgvector/pgvector:pg16)
+# - E2E tests require Python 3.12 and Playwright

 **Zero clippy warnings policy:** Fix ALL clippy warnings before committing, including pre-existing ones in files you didn't change. Never leave warnings behind — treat `cargo clippy` output as a zero-tolerance gate.
 
+**Transaction safety:** Multi-step database operations (INSERT+INSERT, UPDATE+DELETE, read-then-write) MUST be wrapped in a transaction. Never assume sequential calls are atomic. Before committing DB code, ask: "If this crashes between step N and N+1, is the database consistent?" If not, wrap in a transaction. This applies to both postgres and libsql backends.
+
+**UTF-8 string safety:** Never use byte-index slicing (`&s[..n]`) on user-supplied or external strings — it panics on multi-byte characters. Use `is_char_boundary()` to walk backwards from the desired length, or iterate with `char_indices()`. Grep for `[..` in changed files to catch violations.
+
+**Case-insensitive comparisons:** When comparing user-supplied strings (file paths, media types, extension names), always normalize to lowercase first with `.to_ascii_lowercase()`. On case-insensitive filesystems (macOS, Windows), path comparisons must be case-insensitive. File extension checks (`.png`, `.jpg`) and media type checks (`image/jpeg`) are common offenders.
+
+**Decorator/wrapper trait delegation:** When adding a new method to `LlmProvider` (or any trait with decorator wrappers), you MUST update ALL wrapper types to delegate to their inner provider. Grep for `impl LlmProvider for` to find all implementations. Add a test that exercises the method through the full provider chain (`build_provider_chain()`), not just the base impl.
+
+**Sensitive data in logs & events:** Tool parameters and outputs MUST be redacted before logging or broadcasting via SSE/WebSocket. Use `redact_params()` before any `tracing::info!`, `JobEvent`, or SSE emission that includes tool call data. Never log raw parameters from tool calls.
+
+**Test temporary files:** Use the `tempfile` crate for test directories/files. Never hardcode `/tmp/...` paths — they collide in parallel test runs and break on non-Unix platforms.
+
+**Trust boundaries in multi-process architecture:** Data from worker containers is untrusted. The orchestrator MUST validate: tool domain (never execute `Container`-domain tools on the host), nesting depth (server-side tracking, not client-supplied), and parameter sensitivity (redact before logging/broadcasting).
+
 **Mechanical verification before committing:** Run these checks on changed files before committing:
 - `cargo clippy --all --benches --tests --examples --all-features` -- zero warnings
 - `grep -rnE '\.unwrap\(|\.expect\(' <files>` -- no panics in production
 - `grep -rn 'super::' <files>` -- use `crate::` imports
 - If you fixed a pattern bug, `grep` for other instances of that pattern across `src/`
 - Fix commits must include regression tests (enforced by `commit-msg` hook; bypass with `[skip-regression-check]`)
+- Run `scripts/pre-commit-safety.sh` to catch UTF-8, case-sensitivity, hardcoded /tmp, and logging issues

 ### LLM Providers
 
-IronClaw supports multiple LLM backends via the `LLM_BACKEND` env var: `nearai` (default), `openai`, `anthropic`, `ollama`, `openai_compatible`, and `tinfoil`.
-
-**NEAR AI** -- Uses the Chat Completions API with dual auth support. Session token auth (default): authenticates with session tokens (`sess_xxx`) obtained via browser OAuth (GitHub/Google), base URL defaults to `https://private.near.ai`. API key auth: set `NEARAI_API_KEY` (from `cloud.near.ai`), base URL defaults to `https://cloud-api.near.ai`. Both modes use the same Chat Completions endpoint. Tool messages are flattened to plain text for compatibility. Set `NEARAI_SESSION_TOKEN` env var for hosting providers that inject tokens via environment.
-
-**NEAR AI Cloud** -- Uses the OpenAI-compatible Chat Completions API (`https://cloud-api.near.ai/v1/chat/completions`). Authenticates with API keys from `cloud.near.ai`. Auto-selected when `NEARAI_API_KEY` is set (or explicitly via `NEARAI_API_MODE=chat_completions`). Tool messages are flattened to plain text for compatibility. Configure with `NEARAI_API_KEY` and `NEARAI_BASE_URL` (default: `https://cloud-api.near.ai`).

-**OpenAI-compatible** -- Any endpoint that speaks the OpenAI API (vLLM, LiteLLM, OpenRouter, etc.). Configure with `LLM_BASE_URL`, `LLM_API_KEY` (optional), `LLM_MODEL`. Set `LLM_EXTRA_HEADERS` to inject custom HTTP headers into every request (format: `Key:Value,Key2:Value2`), useful for OpenRouter attribution headers like `HTTP-Referer` and `X-Title`.
-
-**Tinfoil** -- Private inference via `https://inference.tinfoil.sh/v1`. Runs models inside hardware-attested TEEs so neither Tinfoil nor the cloud provider can see prompts or responses. Uses the OpenAI-compatible Chat Completions API. Configure with `TINFOIL_API_KEY` and `TINFOIL_MODEL` (default: `kimi-k2-5`).
+Backends: `nearai` (default), `openai`, `anthropic`, `ollama`, `openai_compatible`, `tinfoil` — set via `LLM_BACKEND`. See [src/llm/CLAUDE.md](src/llm/CLAUDE.md) for per-provider auth and configuration details.
 
 ## Database
 
-IronClaw supports two database backends, selected at compile time via Cargo feature flags and at runtime via the `DATABASE_BACKEND` environment variable.
-
-**IMPORTANT: All new features that touch persistence MUST support both backends.** Implement the operation as a method on the `Database` trait in `src/db/mod.rs`, then add the implementation in both `src/db/postgres.rs` (delegate to Store/Repository) and `src/db/libsql_backend.rs` (native SQL).
-
-### Backends
-
-| Backend | Feature Flag | Default | Use Case |
-|---------|-------------|---------|----------|
-| PostgreSQL | `postgres` (default) | Yes | Production, existing deployments |
-| libSQL/Turso | `libsql` | No | Zero-dependency local mode, edge, Turso cloud |
+Dual-backend persistence (PostgreSQL + libSQL/Turso). **All new persistence features must support both backends** — see [src/db/CLAUDE.md](src/db/CLAUDE.md) for schema, SQL dialect differences, adding operations, and libSQL limitations.
 
+Implement every new operation in both `src/db/postgres.rs` and `src/db/libsql/mod.rs`. Test in isolation:
 ```bash
-# Build with PostgreSQL only (default)
-cargo build
-
-# Build with libSQL only
-cargo build --no-default-features --features libsql
-
-# Build with both backends available
-cargo build --features "postgres,libsql"
+cargo check                                          # postgres (default)
+cargo check --no-default-features --features libsql  # libsql only
+cargo check --all-features                           # both
 ```
 
-### Database Trait
-
-The `Database` trait (`src/db/mod.rs`) defines ~60 async methods covering all persistence:
-- Conversations, messages, metadata
-- Jobs, actions, LLM calls, estimation snapshots
-- Sandbox jobs, job events
-- Routines, routine runs
-- Tool failures, settings
-- Workspace: documents, chunks, hybrid search
-
-Both backends implement this trait. PostgreSQL delegates to the existing `Store` + `Repository`. libSQL implements native SQLite-dialect SQL.
-
-### Schema
-
-**PostgreSQL:** `migrations/V1__initial.sql` (351 lines). Uses pgvector for embeddings, tsvector for FTS, PL/pgSQL functions. Managed by `refinery`.
-
-**libSQL:** `src/db/libsql_migrations.rs` (consolidated schema, ~480 lines). Translates PG types:
-- `UUID` -> `TEXT`, `TIMESTAMPTZ` -> `TEXT` (ISO-8601), `JSONB` -> `TEXT`
-- `VECTOR(1536)` -> `F32_BLOB(1536)` with `libsql_vector_idx`
-- `tsvector`/`ts_rank_cd` -> FTS5 virtual table with sync triggers
-- PL/pgSQL functions -> SQLite triggers
-
-**Tables (both backends):**
-
-**Core:**
-- `conversations` - Multi-channel conversation tracking
-- `agent_jobs` - Job metadata and status
-- `job_actions` - Event-sourced tool executions
-- `dynamic_tools` - Agent-built tools
-- `llm_calls` - Cost tracking
-- `estimation_snapshots` - Learning data
-
-**Workspace/Memory:**
-- `memory_documents` - Flexible path-based files (e.g., "context/vision.md", "daily/2024-01-15.md")
-- `memory_chunks` - Chunked content with FTS and vector indexes
-- `heartbeat_state` - Periodic execution tracking
-
-**Other:**
-- `routines`, `routine_runs` - Scheduled/reactive execution
-- `settings` - Per-user key-value settings
-- `tool_failures` - Self-repair tracking
-- `secrets`, `wasm_tools`, `tool_capabilities` - Extension infrastructure
-
 Database configuration: see Configuration section above.
 
-### Current Limitations (libSQL backend)
-
-- **Workspace/memory system** not yet wired through Database trait (requires Store migration)
-- **Secrets store** not yet available (still requires PostgresSecretsStore)
-- **Hybrid search** uses FTS5 only (vector search via libsql_vector_idx not yet implemented)
-- **Settings reload from DB** skipped (Config::from_db requires Store)
-- No incremental migration versioning (schema is CREATE IF NOT EXISTS, no ALTER TABLE support yet)
-- **No encryption at rest** -- The local SQLite database file stores conversation content, job data, workspace memory, and other application data in plaintext. Only secrets (API tokens, credentials) are encrypted via AES-256-GCM before storage. Users handling sensitive data should use full-disk encryption (FileVault, LUKS, BitLocker) or consider the PostgreSQL backend with TDE/encrypted storage.
-- **JSON merge patch vs path-targeted update** -- The libSQL backend uses RFC 7396 JSON Merge Patch (`json_patch`) for metadata updates, while PostgreSQL uses path-targeted `jsonb_set`. Merge patch replaces top-level keys entirely, which may drop nested keys not present in the patch. Callers should avoid relying on partial nested object updates in metadata fields.

+## Execution Priority
+
+Maximize coverage gain per unit of effort:
+
+| Order | Category | Lines Gained | Effort |
+|------:|----------|-------------:|--------|
+| 1 | Trace tests (Tier 2) | ~7,000 | Medium (high leverage, each test covers many modules) |
+| 2 | Unit tests for 0% files (Tier 1 subset) | ~3,500 | Low (pure logic, no infrastructure) |
+| 3 | Web handler tests (Tier 3) | ~4,500 | Medium (axum_test + in-memory DB) |
+| 4 | Extension/MCP/WASM unit tests (Tier 1 remainder) | ~3,500 | Medium |
+| 5 | CLI subcommand tests (Tier 4) | ~2,100 | Low-Medium |
+| 6 | Setup wizard extraction + tests (Tier 5) | ~2,400 | High (requires refactoring) |
+| 7 | LLM provider tests (Tier 1 subset) | ~800 | Medium |
+| 8 | Remaining small files (Tier 6) | ~2,000 | Low |
+
+## Notes
+
+- All trace tests require `--features libsql` and use `TestRigBuilder` from `tests/support/`
+- Web handler tests can use `axum::test` helpers or build the router directly
+- CLI tests should call handler functions directly, not shell out to the binary
+- Setup wizard tests require extracting pure logic from interactive prompts first
+- Sandbox/container tests should verify command construction, not run Docker
+- Worker tests can use `TraceLlm` for the LLM provider, same as trace tests

+# Pre-Merge Review Checklist
+
+Before merging, verify these items. They represent the most common issues caught by automated code reviewers (Copilot, Gemini) on IronClaw PRs.
+
+## Database Operations
+- [ ] Multi-step DB operations are wrapped in transactions (INSERT+INSERT, UPDATE+DELETE, read-modify-write)
+- [ ] Both postgres AND libsql backends updated for any new Database trait methods
+- [ ] Migrations are atomic (SQL execution + version recording in same transaction)
+
+## Security & Data Safety
+- [ ] Tool parameters are redacted via `redact_params()` before logging or SSE/WebSocket broadcast
+- [ ] URL validation resolves DNS before checking for private/loopback IPs (anti-SSRF via DNS rebinding)
+- [ ] Destructive tools have `requires_approval()` returning `Always` or `UnlessAutoApproved`
+- [ ] Data from worker containers is treated as untrusted (tool domain checks, server-side nesting depth)
+- [ ] No secrets or credentials in error messages, logs, or SSE events
+
+## String Safety
+- [ ] No byte-index slicing (`&s[..n]`) on external/user strings -- use `is_char_boundary()` or `char_indices()`
+- [ ] File extension and media type comparisons are case-insensitive (`.to_ascii_lowercase()` before matching)
+- [ ] Path comparisons are case-insensitive where needed (macOS/Windows filesystems)
+
+## Trait Wrappers & Decorator Chain
+- [ ] New `LlmProvider` trait methods are delegated in ALL wrapper types (grep `impl LlmProvider for`)
+- [ ] New trait methods are tested through the full decorator/provider chain, not just the base impl
+- [ ] Default trait method implementations are intentional -- wrappers that silently return defaults are bugs
+
+## Tests
+- [ ] Temporary files/dirs use `tempfile` crate, no hardcoded `/tmp/` paths
+- [ ] Tests don't mutate global statics without synchronization (use per-test state or `serial_test`)
+- [ ] Tests don't make real network requests (use mocks, stubs, or RFC 5737 TEST-NET IPs like 192.0.2.1)
+- [ ] Test names and comments match actual test behavior and assertions
+
+## Comments & Documentation
+- [ ] Code comments match actual behavior (especially route paths, tool names, function semantics)
+- [ ] Spec/README files updated if module behavior changed
+- [ ] Error messages are clear and non-redundant (don't nest tool name inside tool error that already contains it)

+# Agent Module
+
+Core agent logic. This is the most complex subsystem — read this before working in `src/agent/`.
+
+## Module Map
+
+| File | Role |
+|------|------|
+| `agent_loop.rs` | `Agent` struct, `AgentDeps`, main `run()` event loop. Delegates to siblings. |
+| `dispatcher.rs` | Agentic loop for conversational turns: LLM call → tool execution → repeat. Injects skill context. Returns `Response` or `NeedApproval`. |
+| `thread_ops.rs` | Thread/session operations: `process_user_input`, undo/redo, approval, auth-mode interception, DB hydration, compaction. |
+| `commands.rs` | System command handlers (`/help`, `/model`, `/status`, `/skills`, etc.) and job intent handlers. |
+| `session.rs` | Data model: `Session` → `Thread` → `Turn`. State machines for threads and turns. |
+| `session_manager.rs` | Lifecycle: create/lookup sessions, map external thread IDs to internal UUIDs, prune stale sessions, manage undo managers. |
+| `router.rs` | Routes explicit `/commands` to `MessageIntent`. Natural language bypasses the router entirely. |
+| `scheduler.rs` | Parallel job scheduling. Maintains `jobs` map (full LLM-driven) and `subtasks` map (tool-exec/background). |
+| `worker.rs` | Per-job execution for background scheduler jobs: calls LLM, runs tools, handles the reasoning loop. Distinct from `dispatcher.rs`. |
+| `compaction.rs` | Context window management: summarize old turns, write to workspace daily log, trim context. Three strategies. |
+| `context_monitor.rs` | Detects memory pressure. Suggests `CompactionStrategy` based on usage level. |
+| `self_repair.rs` | Detects stuck jobs and broken tools, attempts recovery. |
+| `heartbeat.rs` | Proactive periodic execution. Reads `HEARTBEAT.md`, notifies via channel if findings. |
+| `submission.rs` | Parses all user submissions into typed variants before routing. |
+| `undo.rs` | Turn-based undo/redo with checkpoints. Checkpoints store message lists (max 20 by default). |
+| `routine.rs` | `Routine` types: `Trigger` (cron/event/webhook/manual) + `RoutineAction` (lightweight/full_job) + `RoutineGuardrails`. |
+| `routine_engine.rs` | Cron ticker and event matcher. Fires routines when triggers match. Lightweight runs inline; full_job dispatches to `Scheduler`. |
+| `task.rs` | Task types for the scheduler: `Job`, `ToolExec`, `Background`. Used by `spawn_subtask` and `spawn_batch`. |
+| `cost_guard.rs` | LLM spend and action-rate enforcement. Tracks daily budget (cents) and hourly call rate. Lives in `AgentDeps`. |
+| `job_monitor.rs` | Subscribes to SSE broadcast and injects Claude Code (container) output back into the agent loop as `IncomingMessage`. |
+
+## Session / Thread / Turn Model
+
+```
+Session (per user)
+└── Thread (per conversation — can have many)
+    └── Turn (per request/response pair)
+        ├── user_input: String
+        ├── response: Option<String>
+        ├── tool_calls: Vec<ToolCall>
+        └── state: TurnState (Pending | Running | Complete | Failed)
+```
+
+- A session has one **active thread** at a time; threads can be switched.
+- Turns are append-only. Undo rolls back by restoring a prior checkpoint (message list, not a full thread snapshot).
+- `UndoManager` is per-thread, stored in `SessionManager`, not on `Session` itself. Max 20 checkpoints (oldest dropped when exceeded).
+- Group chat detection: if `metadata.chat_type` is `group`/`channel`/`supergroup`, `MEMORY.md` is excluded from the system prompt to prevent leaking personal context.
+- **Auth mode**: if a thread has `pending_auth` set (e.g. from `tool_auth` returning `awaiting_token`), the next user message is intercepted before any turn creation, logging, or safety validation and sent directly to the credential store. Any control submission (undo, interrupt, etc.) cancels auth mode.
+- `ThreadState` values: `Idle`, `Processing`, `AwaitingApproval`, `Completed`, `Interrupted`.
+- `SessionManager` maps `(user_id, channel, external_thread_id)` → internal UUID. Prunes idle sessions every 10 minutes (warns at 1000 sessions).
+
+## Agentic Loop (dispatcher.rs)
+
+The `dispatcher.rs` module handles **direct conversational turns** (user messages processed inline by the main agent). Background scheduler jobs use `worker.rs` instead — these are two separate execution paths.
+
+```
+run_agentic_loop()  [dispatcher.rs — conversational turns]
+  1. Load workspace system prompt (identity files: AGENTS.md, SOUL.md, etc.)
+  2. Detect group chat from metadata; exclude MEMORY.md if group chat
+  3. Select active skills (keyword/pattern scoring against message content)
+  4. Build skill context block (injected before user message)
+  5. LLM call → text response OR tool calls
+  6. If tool calls:
+     a. Check tool approval (session auto-approvals, pending approval queue)
+     b. Execute tools (parallel via JoinSet)
+     c. Sanitize results through SafetyLayer
+     d. Feed results back → goto 5
+  7. Return AgenticLoopResult::Response or NeedApproval
+```
+
+**Tool approval:** Tools flagged `requires_approval` pause the loop and return `NeedApproval`. The web gateway stores the `PendingApproval` in session state and sends an `approval_needed` SSE event. The user's approval/deny resumes the loop.
+
+**worker.rs vs dispatcher.rs:** `dispatcher.rs` runs the agentic loop for user-initiated conversational turns (holds session lock, tracks turns). `worker.rs` is spawned by the `Scheduler` for background jobs created via `CreateJob` / `/job` — it runs independently of the session and has its own LLM reasoning loop with planning support (`use_planning` flag).
+
+## Command Routing (router.rs)
+
+The `Router` handles explicit `/commands` (prefix `/`). It parses them into `MessageIntent` variants: `CreateJob`, `CheckJobStatus`, `CancelJob`, `ListJobs`, `HelpJob`, `Command`. Natural language messages bypass the router entirely — they go directly to `dispatcher.rs` via `process_user_input`. Note: most user-facing commands (undo, compact, etc.) are handled by `SubmissionParser` before the router runs, so `Router` only sees unrecognized `/xxx` patterns that haven't already been claimed by `submission.rs`.
+
+## Compaction
+
+Triggered by `ContextMonitor` when token usage approaches the model's context limit.
+
+**Token estimation**: Word-count × 1.3 + 4 overhead per message. Default context limit: 100,000 tokens. Compaction threshold: 80% (configurable).
+
+Three strategies, chosen by `ContextMonitor.suggest_compaction()` based on usage ratio:
+- **MoveToWorkspace** — Writes full turn transcript to workspace daily log, keeps 10 recent turns. Used when usage is 80–85% (moderate). Falls back to `Truncate(5)` if no workspace.
+- **Summarize** (`keep_recent: N`) — LLM generates a summary of old turns, writes it to workspace daily log (`daily/YYYY-MM-DD.md`), removes old turns. Used when usage is 85–95%.
+- **Truncate** (`keep_recent: N`) — Removes oldest turns without summarization (fast path). Used when usage >95% (critical).
+
+If the LLM call for summarization fails, the error propagates — turns are **not** truncated on failure.
+
+Manual trigger: user sends `/compact` (parsed by `submission.rs`).
+
+## Scheduler
+
+`Scheduler` maintains two maps under `Arc<RwLock<HashMap>>`:
+- `jobs` — full LLM-driven jobs, each with a `Worker` and an `mpsc` channel for `WorkerMessage` (`Start`, `Stop`, `Ping`, `UserMessage`).
+- `subtasks` — lightweight `ToolExec` or `Background` tasks spawned via `spawn_subtask()` / `spawn_batch()`.
+
+**Preferred entry point**: `dispatch_job()` — creates context, optionally sets metadata, persists to DB (so FK references from `job_actions`/`llm_calls` are valid immediately), then calls `schedule()`. Don't call `schedule()` directly unless you've already persisted.
+
+Check-insert is done under a single write lock to prevent TOCTOU races. A cleanup task polls every second for job completion and removes the entry from the map.
+
+`spawn_subtask()` returns a `oneshot::Receiver` — callers must await it to get the result. `spawn_batch()` runs all tasks concurrently and returns results in input order.
+
+## Self-Repair
+
+`DefaultSelfRepair` runs on `repair_check_interval` (from `AgentConfig`). It:
+1. Calls `ContextManager::find_stuck_jobs()` to find jobs in `JobState::Stuck`.
+2. Attempts `ctx.attempt_recovery()` (transitions back to `InProgress`).
+3. Returns `ManualRequired` if `repair_attempts >= max_repair_attempts`.
+4. Detects broken tools via `store.get_broken_tools(5)` (threshold: 5 failures). Requires `with_store()` to be called; returns empty without a store.
+5. Attempts to rebuild broken tools via `SoftwareBuilder`. Requires `with_builder()` to be called; returns `ManualRequired` without a builder.
+
+Note: the `stuck_threshold` duration is stored but currently unused (marked `#[allow(dead_code)]`). Stuck detection relies on `JobState::Stuck` being set by the state machine, not wall-clock time comparison.
+
+Repair results: `Success`, `Retry`, `Failed`, `ManualRequired`. `Retry` does NOT notify the user (to avoid spam).
+
+## Key Invariants
+
+- Never call `.unwrap()` or `.expect()` — use `?` with proper error mapping.
+- All state mutations on `Session`/`Thread` happen under `Arc<Mutex<Session>>` lock.
+- The agent loop is single-threaded per thread; parallel execution happens at the job/scheduler level.
+- Skills are selected **deterministically** (no LLM call) — see `skills/selector.rs`.
+- Tool results pass through `SafetyLayer` before returning to LLM (sanitizer → validator → policy → leak detector).
+- `SessionManager` uses double-checked locking for session creation. Read lock first (fast path), then write lock with re-check to prevent duplicate sessions.
+- `Scheduler.schedule()` holds the write lock for the entire check-insert sequence — don't hold any other locks when calling it.
+- `cheap_llm` in `AgentDeps` is used for heartbeat and other lightweight tasks. Falls back to main `llm` if `None`. Use `agent.cheap_llm()` accessor, not `deps.cheap_llm` directly.
+- `CostGuard.check_allowed()` must be called **before** LLM calls; `record_llm_call()` must be called **after**. Both calls are separate — the guard does not auto-record.
+- `BeforeInbound` and `BeforeOutbound` hooks run for every user message and agent response respectively. Hooks can modify content or reject. Hook errors are logged but **fail-open** (processing continues).
+
+## Complete Submission Command Reference
+
+All commands parsed by `SubmissionParser::parse()`:
+
+| Input | Variant | Notes |
+|-------|---------|-------|
+| `/undo` | `Undo` | |
+| `/redo` | `Redo` | |
+| `/interrupt`, `/stop` | `Interrupt` | |
+| `/compact` | `Compact` | |
+| `/clear` | `Clear` | |
+| `/heartbeat` | `Heartbeat` | |
+| `/summarize`, `/summary` | `Summarize` | |
+| `/suggest` | `Suggest` | |
+| `/new`, `/thread new` | `NewThread` | |
+| `/thread <uuid>` | `SwitchThread` | Must be valid UUID |
+| `/resume <uuid>` | `Resume` | Must be valid UUID |
+| `/status [id]`, `/progress [id]`, `/list` | `JobStatus` | `/list` = all jobs |
+| `/cancel <id>` | `JobCancel` | |
+| `/quit`, `/exit`, `/shutdown` | `Quit` | |
+| `yes/y/approve/ok` and aliases | `ApprovalResponse { approved: true, always: false }` | |
+| `always/a` and aliases | `ApprovalResponse { approved: true, always: true }` | |
+| `no/n/deny/reject/cancel` and aliases | `ApprovalResponse { approved: false }` | |
+| JSON `ExecApproval{...}` | `ExecApproval` | From web gateway approval endpoint |
+| `/help`, `/?` | `SystemCommand { "help" }` | Bypasses thread-state checks |
+| `/version` | `SystemCommand { "version" }` | |
+| `/tools` | `SystemCommand { "tools" }` | |
+| `/skills [search <q>]` | `SystemCommand { "skills" }` | |
+| `/ping` | `SystemCommand { "ping" }` | |
+| `/debug` | `SystemCommand { "debug" }` | |
+| `/model [name]` | `SystemCommand { "model" }` | |
+| Everything else | `UserInput` | Starts a new agentic turn |
+
+**`SystemCommand` vs control**: `SystemCommand` variants bypass thread-state checks entirely (no session lock, no turn creation). `Quit` returns `Ok(None)` from `handle_message` which breaks the main loop.
+
+## Adding a New Submission Command
+
+Submissions are special messages parsed in `submission.rs` before the agentic loop runs. To add a new one:
+1. Add a variant to `Submission` enum in `submission.rs`
+2. Add parsing in `SubmissionParser::parse()`
+3. Handle in `agent_loop.rs` where `SubmissionResult` is matched (the `match submission { ... }` block in `handle_message`)
+4. Implement the handler method (usually in `thread_ops.rs` for session operations, or `commands.rs` for system commands)

+## SSE Event Types (`SseEvent` in `types.rs`)
+
+The SSE contract — every field is `#[serde(tag = "type")]`:
+
+| Type | When emitted |
+|------|-------------|
+| `response` | Final text response from agent |
+| `stream_chunk` | Streaming token (partial response) |
+| `thinking` | Agent status update during reasoning |
+| `tool_started` | Tool call began |
+| `tool_completed` | Tool call finished (includes success/error) |
+| `tool_result` | Tool output preview |
+| `status` | Generic status message |
+| `job_started` | Sandbox job created |
+| `job_message` | Message from sandbox worker |
+| `job_tool_use` | Tool invoked inside sandbox |
+| `job_tool_result` | Tool result from sandbox |
+| `job_status` | Sandbox job status update |
+| `job_result` | Sandbox job final result |
+| `approval_needed` | Tool requires user approval (pauses agent) |
+| `auth_required` | Extension needs auth credentials |
+| `auth_completed` | Extension auth flow finished |
+| `extension_status` | WASM channel activation status changed |
+| `error` | Error from agent or gateway |
+| `heartbeat` | SSE keepalive (empty payload) |
+
+**SSE serialization:** Events use `#[serde(tag = "type")]` — the wire format is `{"type":"<variant>", ...fields}`. The SSE frame's `event:` field is set to the same string as `type` for easy `addEventListener` use in the browser.
+
+**WebSocket envelope:** Over WebSocket, SSE events are wrapped as `{"type":"event","event_type":"<variant>","data":{...}}`. Ping/pong uses `{"type":"ping"}` / `{"type":"pong"}`. Client-to-server messages (`message`, `approval`, `auth_token`, `auth_cancel`) are defined in `WsClientMessage` in `types.rs`.
+
+**To add a new SSE event:** Use the `add-sse-event` skill (`/add-sse-event`). It scaffolds the Rust variant, serialization, broadcast call, and frontend handler. Also add a matching arm to `WsServerMessage::from_sse_event()` in `types.rs`.
+
+## Auth
+
+All protected routes require `Authorization: Bearer <GATEWAY_AUTH_TOKEN>`. The token is set via `GATEWAY_AUTH_TOKEN` env var. Missing/wrong token → 401. The `Bearer` prefix is compared case-insensitively (RFC 6750).
+
+**Query-string token auth (`?token=xxx`):** Because `EventSource` and WebSocket upgrades cannot set custom headers from the browser, three endpoints also accept the token as a URL query parameter: `/api/chat/events`, `/api/logs/events`, and `/api/chat/ws`. All other endpoints reject query-string tokens. If you add a new SSE or WebSocket endpoint, register its path in `allows_query_token_auth()` in `auth.rs`.
+
+**If no `GATEWAY_AUTH_TOKEN` is configured**, a random 32-character alphanumeric token is generated at startup and printed to the console.
+
+Rate limiting: chat send endpoints are capped at **30 messages per 60 seconds** (sliding window, not per-IP).
+
+## GatewayState
+
+The shared state struct (`server.rs`) holds refs to all subsystems. Fields are `Option<Arc<T>>` so the gateway can start even when optional subsystems (workspace, sandbox, skills) are disabled. Always null-check before use in handlers.
+
+Key fields:
+- `msg_tx` — `RwLock<Option<mpsc::Sender<IncomingMessage>>>` — sends messages to the agent loop; set when `start()` is called on the `Channel`.
+- `sse` — `SseManager` — broadcast hub; call `state.sse.broadcast(event)` from any handler.
+- `ws_tracker` — `Option<Arc<WsConnectionTracker>>` — tracks WS connection count separately from SSE.
+- `chat_rate_limiter` — `RateLimiter` — 30 req/60 s sliding window shared across all chat send callers.
+- `scheduler` — `Option<SchedulerSlot>` — used to inject follow-up messages into running agent jobs.
+- `cost_guard` — `Option<Arc<CostGuard>>` — exposes token usage / cost totals in the status endpoint.
+- `startup_time` — `Instant` — used to compute uptime in the gateway status response.
+- `registry_entries` — `Vec<RegistryEntry>` — loaded once at startup from registry manifests; used by the available extensions API without hitting the network.
+
+Subsystems are wired via `with_*` builder methods on `GatewayChannel` (`mod.rs`). Each call rebuilds `Arc<GatewayState>` — safe to call before `start()`, not after.
+
+## SSE / WebSocket Connection Limits
+
+Both SSE and WebSocket share the same `SseManager` broadcast channel. Key characteristics:
+
+- **Broadcast buffer:** 256 events. A slow client that falls behind will miss events — the `BroadcastStream` silently drops lagged events. SSE clients are expected to reconnect and re-fetch history.
+- **Max connections:** 100 total (SSE + WebSocket combined). Connections beyond the limit receive a 503 / are immediately dropped.
+- **SSE keepalive:** Axum's `KeepAlive` sends an empty event every **30 seconds** to prevent proxy timeouts.
+- **WebSocket:** Two tasks per connection — a sender task (broadcast → WS frames) and a receiver loop (WS frames → agent). When the client disconnects, the sender is aborted and both the SSE connection counter and WS tracker counter are decremented.
+
+## CORS and Security Headers
+
+CORS is restricted to the gateway's own origin (same IP+port and `localhost`+port). Allowed methods: GET, POST, PUT, DELETE. Allowed headers: `Content-Type`, `Authorization`. Credentials are allowed.
+
+All responses include:
+- `X-Content-Type-Options: nosniff`
+- `X-Frame-Options: DENY`
+
+**Request body limit:** 1 MB (`DefaultBodyLimit::max(1024 * 1024)`). Larger payloads return 413.
+
+## Pending Approvals
+
+Tool approval state is **in-memory only** (not persisted to DB). Server restart clears all pending approvals. The `pending_approval` field in `HistoryResponse` is re-populated on thread switch from in-memory state.
+
+## Adding a New API Endpoint
+
+1. Define request/response types in `types.rs`.
+2. Implement the handler in the appropriate `handlers/*.rs` file (or inline in `server.rs` for simple handlers).
+3. Register the route in `start_server()` in `server.rs` under the correct router (`public`, `protected`, or `statics`).
+4. If it is an SSE or WebSocket endpoint, add its path to `allows_query_token_auth()` in `auth.rs`.
+5. If it requires a new `GatewayState` field, add it to the struct and to both the `GatewayChannel::new()` initializer and `rebuild_state()` in `mod.rs`, then add a `with_*` builder method.
