Synchronous hook that lets plugins inspect and optionally block messages
before they are written to the session JSONL file. Primary use case is
private mode... when enabled, the plugin returns { block: true } and the
message never gets persisted.
The hook runs on the hot path (synchronous, like tool_result_persist).
Handlers execute sequentially in priority order. If any handler returns
{ block: true }, the write is skipped immediately. Handlers can also
return a modified message to write instead of the original.
Changes:
- src/plugins/types.ts: add hook name, event/result types, handler map entry
- src/plugins/hooks.ts: add runBeforeMessageWrite() following tool_result_persist pattern
- src/agents/session-tool-result-guard.ts: invoke hook before every originalAppend() call
- src/agents/session-tool-result-guard-wrapper.ts: wire hook runner to the guard

Adds a complete Linq iMessage channel adapter that replaces the existing
iMessage channel's Mac Mini + dedicated Apple ID + SSH wrapper + Full Disk
Access setup with a single API key and phone number.
Core implementation (src/linq/):
- types.ts: Linq webhook event and message types
- accounts.ts: Multi-account resolution from config (env/file/inline token)
- send.ts: REST outbound via Linq Blue V3 API (messages, typing, reactions)
- probe.ts: Health check via GET /v3/phonenumbers
- monitor.ts: Webhook HTTP server with HMAC-SHA256 signature verification,
replay protection, inbound debouncing, and full dispatch pipeline integration
Extension plugin (extensions/linq/):
- ChannelPlugin implementation with config, security, setup, outbound,
gateway, and status adapters
- Supports direct and group chats, reactions, and media
Wiring:
- Channel registry, dock, config schema, plugin-sdk exports, and plugin
runtime all updated to include the new linq channel

Pre-existing test mocks lacked pendingMessagingMediaUrls and
messagingToolSentMediaUrls fields added by the media dedup feature,
causing runtime errors in handleToolExecutionEnd.

Make before_agent_start override merging preserve the first defined
model/provider override so higher-priority hooks cannot be overwritten by
lower-priority handlers, and align the corresponding test title and
expectation with the intended precedence behavior.

Layer 1: Hook merger tests verify modelOverride/providerOverride are
correctly propagated through the before_agent_start merger with
priority ordering, backward compatibility, and field isolation.
Layer 2: Pipeline wiring tests verify the earlyHookResult passthrough
contract between run.ts and attempt.ts, graceful error degradation,
and that overrides correctly modify provider/model variables.
19 tests total across 2 test files.
Enable plugins to override the model and provider for agent runs by
returning modelOverride/providerOverride from the before_agent_start
hook. The hook is now invoked early in run.ts (before resolveModel)
so overrides take effect. The result is passed to attempt.ts via
earlyHookResult to prevent double-firing.
This enables security-critical use cases like routing PII-containing
prompts to local models instead of cloud providers.
