* feat: merge http/web_fetch tools, add tool output stash for large responses
Merge `web_fetch` into `http` tool with smart approval: plain GETs (no
headers, no body) run without approval and follow redirects with SSRF
re-validation per hop; all other requests require approval as before.
Add `tool_output_stash` on JobContext so full tool outputs are preserved
before safety-layer truncation. The `json` tool gains a
`source_tool_call_id` parameter to reference stashed outputs, enabling
reliable parsing of large API responses that exceed the 100KB context
limit.
Other improvements:
- Descriptive User-Agent header using CARGO_PKG_VERSION
- Truncation now keeps partial data + hint about source_tool_call_id
- System prompt reinforces tool_calls over narration
- json tool query/stringify handle pre-parsed (non-string) data

* style: rename shadowed data binding for clarity in json tool
Address PR review: rename owned `data` to `data_value` before
re-binding as `let data = &data_value` to make ownership explicit.

* fix(ci): mark network-dependent trace tests as #[ignore]
The weather_sf and baseball_stats tests hit live external APIs (wttr.in,
ESPN) which are unreliable in CI. Mark them #[ignore] so they don't
block the pipeline. Run locally with `--ignored` to include them.

* fix: replay recorded HTTP exchanges in trace tests instead of hitting live APIs
Wire ReplayingHttpInterceptor into TestRig when the trace fixture
contains http_exchanges. This replays recorded responses instead of
making live network calls, making tests deterministic and CI-stable.
Add captured HTTP responses to weather_sf.json (wttr.in) and
baseball_stats.json (ESPN API) fixtures.
Revert #[ignore] on both tests — they now run offline.

* fix: recover inline bracket-format tool calls from LLM text responses
When flatten_tool_messages converts tool calls to text like
`[Called tool `http` with arguments: {...}]` for NEAR AI compatibility,
the LLM sometimes echoes this format back in its text responses instead
of using proper tool_calls. Add recovery for this bracket format in
recover_tool_calls_from_content and strip it in clean_response so
users don't see raw tool call syntax.

* fix: scan inbound messages for leaked secrets before LLM processing (#393)
Add scan_inbound_for_secrets() to SafetyLayer that reuses the existing
leak detector on user input. Wire it into thread_ops.rs after the policy
check so messages containing API keys or tokens are rejected early,
preventing the LLM from echoing them back and triggering outbound
leak-detection error loops.

* fix: unify inbound secret scan warning messages
Both the detected-secret and error branches now show the same
actionable message guiding users to remove secrets and use the
config system instead.
Addresses Gemini review feedback on PR #433.

Prevent personal memory (MEMORY.md) from leaking into group chat contexts
by adding system_prompt_for_context(is_group_chat) to the workspace. Add
channel-specific formatting hints (Discord, Telegram, Slack, WhatsApp),
runtime metadata injection, group chat behavioral guidance with NO_REPLY
silent token, safety rules in the system prompt, tool call style guidance,
wrap_external_content() for untrusted data, and improved workspace seed
files with richer identity/soul/agent templates and heartbeat checklist.

* refactor: consolidate tool approval into single param-aware method
Replace the two confusing approval methods (requires_approval() and
requires_approval_for()) with a single requires_approval(&self, params)
returning a 3-variant ApprovalRequirement enum (Never, UnlessAutoApproved,
Always). This enables param-aware approval decisions: HTTP calls without
auth headers now skip approval entirely, while authenticated requests
always require it. Shell tool merges its destructive-command detection
into the same method.

* feat: add credential injection to built-in HTTP tool
Wire the WASM credential injection system into the built-in HTTP tool
so credentials are auto-injected at the boundary (zero-exposure model).
- Add SharedCredentialRegistry: thread-safe, append-only registry of
credential mappings populated by WASM tools at registration time
- Add credential_detect module with broad auth detection for headers
(12 exact + 5 substring matches), header values (7 auth scheme
prefixes), and URL query params (17 exact + 5 substring matches)
- HttpTool now accepts optional credential registry + secrets store,
auto-injects matching credentials in execute(), and uses broader
auth detection in requires_approval()
- ToolRegistry passes credential registry to HttpTool at startup and
populates it when WASM tools register
- Remove old hardcoded AUTH_HEADER_NAMES / has_auth_headers in favor
of the new params_contain_manual_credentials()
Co-Authored-By: Claude Opus 4.6 <[email protected]>
* fix: address PR #274 review comments (query param injection, lock poisoning, visibility)
- Fix injected query params not being sent on outbound HTTP requests by
also calling .query() on the RequestBuilder alongside parsed_url mutation
- Recover from poisoned RwLock in SharedCredentialRegistry instead of
silently ignoring failures, with tracing::warn for visibility
- Narrow inject_credential and host_matches_pattern to pub(crate) to
avoid committing to them as stable public API

* 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)
Co-Authored-By: Claude Opus 4.6 <[email protected]>
* 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.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
* 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.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
* 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.

Extends the WASM sandbox with HTTP API capabilities, secrets management,
tool aliasing, and leak detection. Key security principle: WASM never
sees credentials, injection happens at host boundary.
New modules:
- secrets: AES-256-GCM encrypted storage with HKDF key derivation
- leak_detector: Aho-Corasick + regex pattern matching for secret exfiltration
- capabilities: Extended capability system (HTTP, ToolInvoke, Secrets)
- allowlist: HTTP endpoint validation with glob patterns
- credential_injector: Host-boundary credential injection
- rate_limiter: Sliding window per-tool rate limiting
- storage: WASM binary storage with BLAKE3 integrity verification
Leak detection happens at two points:
1. Before HTTP request (prevents exfiltration via URL/headers/body)
2. After response (prevents exposure in outputs returned to WASM)
