* fix: comprehensive security hardening across all layers
Critical:
- Replace --dangerously-skip-permissions with explicit tool allowlist
via settings.json (Claude Code bridge)
- Constant-time token comparison (subtle crate) in web auth and
orchestrator auth to prevent timing attacks
High:
- Revoke tokens and clean up handles on container creation failure
- Drop SETUID/SETGID capabilities from containers (keep only CHOWN)
- Disable redirect following in HTTP tool and WASM wrapper (SSRF)
- Reject URL userinfo (@) in WASM allowlist parser (host confusion)
- Fix binary body bypassing leak detection (from_utf8 -> from_utf8_lossy)
- Protect identity files from LLM overwrites (prompt injection defense)
- Prevent tool shadowing: built-in tools cannot be replaced dynamically
- User-scoped job APIs: list/detail/cancel/restart/prompt/events/files
- CORS restricted to localhost origins, WebSocket origin validation
- Sandbox shell fail-closed: no silent fallback to unsandboxed execution
- Scrub secrets from log broadcaster before SSE broadcast
- XSS sanitization on rendered markdown in web UI
- WASM epoch ticker thread so timeout deadlines actually fire
Medium:
- Cap state transition history at 200 entries
- SSE/WebSocket connection limit (100 max)
- Request body size limit (1MB)
- Response body size limit enforcement in WASM HTTP
- UTF-8 safe string truncation (routine engine, shell tool)
- Fix PolicyAction::Sanitize to actually run the sanitizer
- TOCTOU fix in scheduler and context manager (hold write lock)
- Project file serving moved behind auth
- Path traversal guard on project_id
- Session file permissions set to 0600 on unix
- AtomicUsize for routine running_count (panic-safe)
- Completion detection hardened against false positives and tool injection
- Tool output no longer drives job completion (only LLM response)

* fix: address security review findings across all layers
- Fix path traversal sandbox bypass via lexical normalization (file.rs)
- Fix SSRF via DNS rebinding with pre-request hostname resolution (http.rs)
- Add token budget enforcement on LLM calls (reasoning.rs, state.rs)
- Fix cross-user chat history leak with ownership verification (store.rs, server.rs)
- Add sliding-window rate limiter on gateway chat endpoint (server.rs)
- Harden extension install: HTTPS-only, 50MB cap, WASM magic validation (manager.rs)
- Add destructive command blocklist that overrides shell auto-approval (shell.rs)
- Add 5MB response body size cap to HTTP tool (http.rs)

* refactor: deduplicate shared helpers and remove dead code
Extract floor_char_boundary and llm_signals_completion into src/util.rs,
unifying diverging phrase lists from agent/worker.rs and worker/runtime.rs.
Remove dead RespondResult::usage(), duplicate PROTECTED_IDENTITY_FILES
constant, double LeakDetector scanning in WebLogLayer, and invalid
0.0.0.0 origin from WebSocket allow list.

* fix: address PR review findings and CI test failures
- Fix record_failed_approve: .truncate(true) wiped the attempts file
before reading, so failed pairing attempts never accumulated and
rate limiting never triggered.
- Guard wizard WASM test: skip gracefully when channel build artifacts
are absent (CI doesn't compile wasm32-wasip2 targets).
- Fix DNS rebinding check: use port 0 instead of hardcoded 443, since
the port is irrelevant for hostname resolution.
- Remove hardcoded CORS port 3001: the dynamic addr.port() entries
already cover the actual server port.
- Require WebSocket Origin header: reject connections that omit it
entirely, since browsers always send Origin for WS upgrades and a
missing header indicates a non-browser client bypassing the check.

* fix: address second round of PR review findings
- store.rs: reintroduce file locking around read-modify-write in
record_failed_approve (concurrent callers could clobber each other).
- sse.rs: replace load+check+fetch_add with atomic fetch_update in both
subscribe_raw() and subscribe() to prevent overshooting max_connections.
- ws.rs: decrement WS tracker before early return when subscribe_raw()
returns None (connection limit reached), fixing a counter leak.
- server.rs: parse WS Origin host exactly instead of prefix matching,
preventing bypass via crafted origins like http://localhost.evil.com.
- workspace_integration.rs: skip tests gracefully when Postgres is
unreachable instead of panicking (fixes 10 CI failures).

* fix: add Origin header to WS integration tests
The Origin header requirement added in a3b0190 broke the WS gateway
integration tests. Test clients now send Origin: http://127.0.0.1:{port}
to match the server's localhost validation.

Introduce a Database trait abstraction (~60 async methods) enabling
compile-time backend selection between PostgreSQL and libSQL/Turso.
Convert all modules from concrete Store to Arc<dyn Database>, add
LibSqlSecretsStore and LibSqlWasmToolStore implementations, wire
libsql stores throughout CLI and main entry points, and make the
setup wizard backend-agnostic.
Key changes:
- src/db/: Database trait, PostgresDatabase adapter, LibSqlBackend
with native SQLite-dialect SQL, and idempotent migration system
- src/secrets/store.rs: LibSqlSecretsStore (all 8 trait methods)
- src/tools/wasm/storage.rs: LibSqlWasmToolStore (all 7 trait methods)
- src/main.rs, cli/tool.rs, cli/mcp.rs: backend-conditional wiring
- src/setup/channels.rs: SecretsContext uses Arc<dyn SecretsStore>
- Feature-gate postgres-only tests and examples

- Add dedicated "heartbeat" target in memory_write tool so the LLM
routes HEARTBEAT.md writes to the database instead of the filesystem
- Update tool description to clarify it's database-backed storage
- Broadcast heartbeat notifications to all channels when no explicit
notify target is configured, instead of silently logging them

- Add escape_telegram_markdown() to handle underscores in tool names
(e.g., build_software was breaking Telegram's Markdown parser)
- Use Telegram-compatible *bold* syntax instead of **bold**
- Clarify workspace memory vs filesystem tool descriptions to prevent
LLM from using read_file on memory_tree paths
- Update build_software to strongly prefer Rust WASM for agent tools
- Rewrite WASM tool template to use Component Model with wit_bindgen
instead of outdated extern "C" approach

- Directories indicated by trailing `/` instead of is_directory field
- Files are plain strings, dirs with children are objects
- Remove redundant name/path (just show name in tree)
- Remove preview and updated_at (use memory_read if needed)
- Output is just the tree array, no wrapper object
Example: ["MEMORY.md", {"daily/": ["2024-01-15.md"]}, "projects/"]

The memory_tree tool provides a hierarchical view of the workspace
with configurable depth (default 1). This is more useful for
exploring nested directory structures.
