Sent Hindsight retain timestamps with local timezone offsets and supplied timestamps for automatic and queued retains. Added regression coverage for client serialization and backend timestamp propagation.\n\nFixes #2363
Added two regression tests covering the bidirectional reporter scenario:
clearing hindsight.bankId after a non-empty value rebuilds the live state
and routes subsequent retainBatch calls to the recomputed bank under both
per-project and global scoping. The PR's existing fix already handles
this direction; these lock the contract in place explicitly.
Fixes#1902
Coalesced synchronous Hindsight routing setting hooks into one serialized
session rebuild so cwd reloads and multi-setting updates cannot have
multiple continuations capture the same old state and leak fresh
session listeners.
Also re-read the current state after awaiting the previous queue flush
before installing the replacement state, so an unexpected concurrent
owner cannot leave the actual current state undisposed.
Fixes#1902
Mid-session edits to hindsight.bankId / bankIdPrefix / scoping kept the
active HindsightSessionState pinned to the bank selected at session
start, so retain/recall/reflect calls landed in the stale bank. Settings
hooks now fire onHindsightScopeChanged; the backend rebuilds the
primary state against the recomputed scope, disposing the previous one
after flushing its queue so queued tool-initiated retains still land in
the bank they were enqueued for.
Also:
- Renamed ensureBankMission to ensureBankExists. The old version
skipped creation entirely when bankMission was blank, so the first
mental-model POST (auto-seed) could land against a never-PUT bank.
Bank creation is now idempotent and unconditional, and runs before
mental-model bootstrap.
- Fixed AgentSession.dispose to flush the retain queue BEFORE clearing
the session state pointer. Reversed, HindsightRetainQueue.#doFlush's
identity guard would see the cleared pointer and drop the spliced
batch with a 'session vanished' warning.
- Snapshotted hindsightScopeCallbacks before iterating because each
rebuild subscribes a fresh callback inside the same fire; iterating
the live Set would spin.
Fixes#1902
- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
- Added `HindsightSessionState` to `AgentSession` and bound hindsight lifecycle hooks to session state.
- Removed global hindsight state/queue handling and replaced it with per-session `HindsightRetainQueue` batching and scoped flushing.
- Reworked recall, reflect, and retain tools to use `session.getHindsightSessionState()` instead of sessionId-based lookup.
- Updated SDK/task/backend/controller flows to pass `session`/`parentHindsightSessionState`, scope `/memory` behavior, and document it in changelog.
- Added mental-model settings and config defaults for enablement, auto-seed, refresh interval, and render budget.
- Added built-in mental-model seeds and scope-aware rendering with `<mental_models>` extraction, truncation, and tag handling.
- Added `/memory mm` aliases and handlers for list, show, refresh, history, seed, reload, and delete commands.
- Added client APIs and bootstrap/cache wiring so snippets refresh and inject into prompts on startup.
- Added tests covering seed scope behavior, rendering caps, diffs, and backend/session reload behavior.
- Added an optional `aliasOf` link and a `pickPrimaryState` helper to track reusable parent Hindsight state.
- Updated task-depth subagent startup to reuse the latest primary state's bank, client, config, tags, and missions while returning silently when no parent exists.
- Skipped alias states in recall-snippet selection and enqueue so auto-recall/retain work only on the parent session.
- Removed the `@vectorize-io/hindsight-client` dependency from both package manifests.
- Added a local `HindsightApi` client and changed `createHindsightClient` to instantiate it.
- Replaced `HindsightClient` imports/types with `HindsightApi` across backend, bank, and tests.
- Implemented `HindsightApi` `#request` handling with `fetch`, safe JSON parsing, and `HindsightError` on failures.
- Standardized Hindsight context output to emit `<memories>` blocks and updated retention stripping to remove both `<memories>` and legacy `<hindsight_memories>`/`<relevant_memories>` tags.
- Renamed built-in Hindsight tool entry points and labels from `hindsight_retain`/`hindsight_recall`/`hindsight_reflect` to `retain`, `recall`, and `reflect`, including tool availability checks.
- Added a new optional `beforeAgentStartPrompt` hook to `MemoryBackend` and implemented it in the Hindsight backend to recall long-term context for the first turn.
- Updated `AgentSession` startup flow to inject the recalled context into the turn-specific system prompt before the first response is generated.
- Preserved `<hindsight_memories>` tags in Hindsight developer instructions and added tests for first-turn injection and state caching.
- Added `memory.backend` and `hindsight.*` settings schema with migration from `memories.enabled` legacy mode.
- Added Hindsight memory backend runtime modules for resolved config, client creation, bank ID derivation, and state lifecycle.
- Added off/local/hindsight backends and resolver wiring across SDK, commands, and compaction context.
- Added `hindsight_recall`, `hindsight_reflect`, and `hindsight_retain` tools with schema validation and backend gating.
- Added Memory tab metadata and symbols to expose backend selection in the settings UI.
- Added package export barrels and tests for bank ID, content formatting, and hindsight config env precedence.
