fix(reflect): disable source facts in search_observations to prevent context overflow (#669)
search_observations in the reflect agent hardcoded include_source_facts=True
with max_source_facts_tokens=-1 (unlimited). For banks with many observations
backed by thousands of facts, a single tool call could produce 300K+ tokens,
exceeding the default 100K context budget and causing forced synthesis with
an empty 'Retrieved Data' section.

The reflect agent synthesizes from observations, not raw backing facts.
Disable source facts to keep payloads proportional to observation count
(~6K vs ~310K in the reporter's case).

The consolidation path already has configurable source fact limits (PR #509,
v0.4.17). The reflect path was not updated.

Fixes #668

fix(entity_resolver): prevent _pending_stats/_pending_cooccurrences memory leak (#662)
* fix(entity_resolver): prevent _pending_stats/_pending_cooccurrences memory leak

Add discard_pending_stats() to EntityResolver to clean up both pending dicts
for the current task key. Call it at the start of each _run_db_work attempt so
that exceptions between accumulation and flush_pending_stats() — including
deadlock retries — never leave stale entries keyed by recycled task IDs.

Fixes #660

* test(entity_resolver): add unit tests for discard_pending_stats()

Covers: clears both dicts for current task, is idempotent when empty,
and does not touch entries belonging to other task keys.
No database required — purely in-memory logic.

test: add unit tests for pg_trgm auto-detection and ValidationResult.accept_with() enrichment (#650)
* test: add unit tests for pg_trgm auto-detection and ValidationResult.accept_with() enrichment

Two recent PRs landed without dedicated tests:
- #626/#649 (pg_trgm fallback in EntityResolver): add 5 mocked unit tests
  covering the trigram→full fallback, single-check guarantee, and sticky
  downgrade behaviour.
- #639 (accept_with() enrichment): add 7 pure unit tests for the factory
  method plus 5 integration tests verifying the engine applies enriched
  contents (retain) and tags/tag_groups (recall) returned by validators.
  Also verifies RecallContext carries tag filter state.

* fix: remove 504 from reflect OpenAPI spec to fix progenitor Rust client build

progenitor-impl-0.11.2 panics with `assertion failed: response_types.len() <= 1`
when an endpoint declares more than one response type. PR #643 added
`responses={504: ...}` to the reflect decorator, which injected a second
response type into the generated OpenAPI spec and broke the Rust client build.

Remove the `responses=` kwarg — the 504 is still raised at runtime via
JSONResponse(status_code=504), it just won't appear in the OpenAPI schema.
Regenerate openapi.json accordingly.

* chore: sync generated files and ruff formatting (lint + docs skill)

Add wall-clock timeout to reflect operations (#643)
* Initial plan

* feat: add wall-clock timeout to reflect operations (fixes vectorize-io/hindsight#642)

Add a configurable wall-clock timeout (default: 300s / 5 minutes) for
the entire reflect operation. This prevents reflect calls from hanging
for up to 40 minutes when LLM calls are slow or iteration counts are
high.

Changes:
- Add DEFAULT_REFLECT_WALL_TIMEOUT (300s) config constant
- Add HINDSIGHT_API_REFLECT_WALL_TIMEOUT env variable support
- Wrap run_reflect_agent() with asyncio.wait_for() in reflect_async()
- Return HTTP 504 on timeout in the reflect HTTP endpoint
- Add unit test for wall-clock timeout enforcement

Fix pg_trgm unavailability causing startup crash and silent retain failures (#626) (#649)
On managed PostgreSQL services (e.g. Azure Flexible Server), the pg_trgm
extension may not be available, causing two failures:

1. Migration c1a2b3d4e5f6 crashes on CREATE EXTENSION
2. Even if migration is bypassed, the default 'trigram' entity lookup
   strategy uses the % operator which requires pg_trgm, causing retain
   background tasks to fail silently

Changes:
- Migration now gracefully skips pg_trgm and index creation if the
  extension cannot be loaded
- EntityResolver auto-detects pg_trgm availability on first use and
  falls back to 'full' lookup strategy with a warning log

feat(extensions): add context enrichment to OperationValidatorExtension (#639)
Validators can now return enriched data via ValidationResult.accept_with()
instead of only accepting or rejecting operations. The engine applies
returned fields (contents, tags, tag_groups) to the operation parameters.

- Add accept_with() factory to ValidationResult with optional enrichment
  fields: contents, tags, tags_match, tag_groups
- Add tags, tags_match, tag_groups to RecallContext so validators can
  see current filter state
- Update _validate_operation to return ValidationResult
- Apply enrichment from result at all retain (2 sites) and recall call
  sites in MemoryEngine
- Existing validators using accept()/reject() work unchanged

fix: strip markdown code fences from all LLM providers, not just local (#646)
LLM providers like MiniMax wrap JSON responses in markdown code fences
(```json ... ```), causing JSON parse failures and 5-11 retries per
extraction. The existing fence stripping logic was gated to only
"lmstudio" and "ollama" providers (and for Ollama, unreachable due to
the _call_ollama_native redirect).

Changes:
- Extract _strip_code_fences() helper function
- Apply fence stripping to all providers in call() (not just local)
- Add fence stripping safety net to _call_ollama_native()
- Add 10 tests covering bare JSON, fenced JSON, malformed fences,
  and real-world MiniMax response format

fix(recall): reject empty queries with 400 and fix SQL parameter gap (#632)
* fix(recall): reject empty queries with 400 and fix SQL parameter gap causing IndeterminateDatatypeError

When query text contains only punctuation/symbols (no word characters after
normalization), the BM25 arms are skipped but the old code still placed `limit`
at \$3 in the params list. If tags or tag_groups were also set, their params
(\$4+) were referenced in the SQL while \$3 was a gap, causing PostgreSQL to
raise IndeterminateDatatypeError.

Fix the parameter layout so `limit` is only appended to params when tokens are
present (i.e. when BM25 arms actually use LIMIT \$3), and shift tags_param_idx
from 4 to 3 in the no-tokens path.

Also add a field_validator on RecallRequest.query that rejects empty-after-
normalization queries at the API layer with a 400 before they reach the DB.

* refactor: extract tokenize_query helper and reuse in RecallRequest validator

fix: MCP tool calls fail when MCP_AUTH_TOKEN and TENANT_API_KEY differ (#635)
* fix: MCP tool calls fail when MCP_AUTH_TOKEN and TENANT_API_KEY differ

When both HINDSIGHT_API_MCP_AUTH_TOKEN and ApiKeyTenantExtension are
configured with different values, MCP transport auth passes but tool
execution fails because the MCP token gets re-validated against the
tenant API key in the engine layer.

Add mcp_authenticated flag to RequestContext so the engine skips tenant
re-validation when MCP transport auth already succeeded.

Fixes #627

* test: strengthen assertion to verify no auth error in tool response

The original test only checked that "banks" key existed in the response,
which was true even for error responses like {"error": "...", "banks": []}.
Now asserts "error" not in parsed to properly catch auth failures.

feat: fact_types and mental model exclusion filters for reflect (#615)
* feat: add fact_types and mental model exclusion filters to reflect and mental models

Adds three new filtering options to both the reflect endpoint and mental model creation/refresh:

- `fact_types`: restrict which fact types (world, experience, observation) are retrieved.
  Disables irrelevant agent tools entirely (no wasted tokens).
- `exclude_mental_models`: skip the search_mental_models tool altogether.
- `exclude_mental_model_ids`: exclude specific mental models by ID (merged with the
  existing self-exclusion logic during mental model refresh).

For mental models, options are persisted in the existing `trigger` JSONB column so they
are automatically applied on every refresh. The `UpdateMentalModelRequest` already
proxies `trigger`, so no extra endpoint changes are needed.

Also fixes the test fixture (`pg0_db_url` in conftest.py) to correctly resolve pg0://
URLs and run migrations before tests, which was causing all DB-dependent tests to fail
with "relation public.banks does not exist" when HINDSIGHT_API_DATABASE_URL=pg0://uuuu.

* fix: guard against disabled-tool hallucination and regenerate clients

- Add enabled_tools guard in reflect agent: if an LLM calls a tool that
  was excluded (e.g. recall when fact_types=["observation"]), return an
  error result instead of executing it
- Regenerate OpenAPI spec and all SDK clients (Go, Python, TypeScript)
  to include new fact_types / exclude_mental_models fields

* fix: add missing ReflectRequest fields in Rust CLI struct initializers

* fix: filter hallucinated tool calls before trace to prevent disabled tools appearing in results

* chore: merge main, fix lint formatting and update skills openapi.json

* feat: expose fact_types, exclude_mental_models, exclude_mental_model_ids in control plane UI

* fix: add missing trigger fields to MentalModel type in control plane api.ts

* fix: add missing trigger fields to local MentalModel interface in mental-models-view

* feat: tabbed mental model dialogs (Basic / Options tabs)

* refactor: shared FactTypeFilter component, tabbed mental model dialogs use General tab, clean up labels

* feat: pill-style toggle buttons for fact type filter (blue/emerald/amber per type)

* fix: add spacing between Fact Types label and pills, rename to Exclude all mental models

Fix non-atomic async operation creation (#619)
* Fix non-atomic async operation creation in _submit_async_operation

Previously the method performed two separate database round-trips:
1. INSERT into async_operations with no task_payload (null)
2. submit_task → UPDATE to set task_payload

A process crash or network error between steps 1 and 2 left a row with
task_payload IS NULL permanently. The worker's claim query requires
task_payload IS NOT NULL, so these orphaned rows could never be picked up
and the queue appeared degraded indefinitely.

Fix: build full_payload before the INSERT and include task_payload in the
same INSERT statement, making operation creation atomic. submit_task is
still called afterwards — for SyncTaskBackend it executes the task
immediately (unchanged behaviour); for BrokerTaskBackend it becomes an
idempotent UPDATE (payload already set) kept for symmetry.

* Preserve datetime payloads in atomic async insert

Fix orphaned batch_retain parents when child fails via unhandled exception (#618)
* Fix orphaned batch_retain parents when child fails via unhandled exception

When a child retain operation fails with an unhandled exception (e.g. a DB
constraint violation), the memory engine's transaction is rolled back entirely,
including any call to _maybe_update_parent_operation. The poller's fallback
_mark_failed then updates the child status but leaves the parent batch_retain
permanently stuck in 'pending'.

Fix: wrap _mark_failed in a transaction and call a new poller-level
_maybe_update_parent_operation after marking the child failed. This mirrors
the memory engine's own parent-update logic and ensures the parent is
resolved to completed/failed regardless of how the child failure was detected.

The poller's implementation locks the parent row, checks all siblings, and
only finalises the parent once all siblings have reached a terminal state.
Errors in parent propagation are logged but do not affect the child failure
path, which is the critical state change.

* Add tests for _mark_failed parent propagation in WorkerPoller

Tests cover the new _maybe_update_parent_operation logic:
- Last sibling fails → parent batch_retain becomes failed
- Sole child fails → parent becomes failed
- Sibling still pending → parent stays pending (no premature resolution)
- No parent in result_metadata → safe no-op
- End-to-end: unhandled exception via execute_task propagates to parent

Fix entity_id null constraint for non-ASCII entity names (#612)
* Fix entity_id null constraint for non-ASCII entity names (Turkish İ etc.)

Python's str.lower() and PostgreSQL's LOWER() produce different results for
some Unicode characters. The most common case is Turkish İ (U+0130):
  Python:     'İstanbul'.lower() == 'i\u0307stanbul' (i + combining dot, 2 chars)
  PostgreSQL: LOWER('İstanbul') == 'istanbul' (plain i, 1 char)

In _resolve_from_candidates, the fallback SELECT for conflicted entity names
passed Python-lowercased strings to LOWER(canonical_name) = ANY($names), so
PostgreSQL couldn't match them. entity_ids[idx] stayed None, which then
caused a NOT NULL violation on unit_entities.entity_id, failing the entire
retain.

Fix: pass original mixed-case names to the fallback SELECT and use
LOWER(canonical_name) = ANY(SELECT LOWER(n) FROM unnest($2) AS n) so
PostgreSQL lowercases both sides identically. The query also returns the
original input_name so we can add a Python-lowercased key to id_by_name
for the assignment loop that uses Python-lowercased keys.

* Add regression test for Unicode entity conflict

fix: prevent silent memory loss on consolidation LLM failure (#601)
* fix: prevent silent memory loss on consolidation LLM failure

When all LLM retries are exhausted during consolidation, memories were
being marked consolidated_at unconditionally, permanently excluding them
from future consolidation runs without producing any observations.

Fix with two complementary mechanisms:
- Adaptive batch splitting: on LLM failure, the batch is halved and
  retried recursively down to batch_size=1, recovering most transient
  failures (rate limits, Pydantic validation on long prompts) without
  operator intervention
- consolidation_failed_at column: only single-memory batches that still
  fail after all retries are marked here instead of consolidated_at, so
  they remain visible and retryable
- New API endpoint POST /v1/default/banks/{bank_id}/consolidation/retry-failed
  resets these memories for the next consolidation run

* chore: regenerate OpenAPI spec

* fix: rename consolidation endpoint from /retry-failed to /recover

* fix: add consolidation_failed_at column, adaptive batch splitting, and recovery API

- Migration a3b4c5d6e7f8: add consolidation_failed_at TIMESTAMPTZ column to
  memory_units with an index for efficient failure queries; properly chains off
  g7h8i9j0k1l2 (backsweep_orphan_observations)
- Consolidator: filter pending memories with consolidation_failed_at IS NULL
  so failed memories are not re-fetched in an infinite loop
- Consolidator: adaptive batch splitting — when a batch exhausts all 3 LLM
  retries, halve it and retry sub-batches recursively; only single-memory
  batches that also exhaust all retries get consolidation_failed_at set
- New tests (9 total) covering: adaptive splitting recovers all memories,
  larger batch splitting, single-memory permanent failure, exclusion from
  next run, partial batch failure, recover resets columns, recover returns
  0 when none failed, recover-then-consolidate succeeds, HTTP endpoint

* chore: regenerate Go, Python, TypeScript clients with recover consolidation endpoint

* feat: add Recover Consolidation action to bank Actions dropdown

* style: apply ruff formatting to http.py and config.py

* fix: handle consolidation scope in large batch test mock LLM

The mock LLM was returning {"facts": ...} for ALL calls including consolidation.
Consolidation doesn't use skip_validation=True so it expects a _ConsolidationBatchResponse
instance, not a raw dict. Before this PR consolidation silently swallowed the AttributeError
(failed=False was returned); now failed=True triggers adaptive splitting and timeouts.

Fix: return _ConsolidationBatchResponse() when scope=="consolidation".

* fix: restrict claude-agent-sdk to macOS platform only (no Linux wheel available)

Also fix pre-existing type errors: use setattr for XLM-RoBERTa monkey-patch
and add missing reranker_local_fp16/bucket_batching/batch_size fields to main.py config constructor.

* fix: add UV_INDEX_STRATEGY=unsafe-best-match to fix markupsafe cp314 wheel conflict

PyTorch CPU index serves markupsafe==3.0.3 with only cp314 wheels.
uv's default first-index strategy stops at the first index with any version
even if no compatible wheel exists. unsafe-best-match searches all indices
for the best compatible wheel, falling back to PyPI for markupsafe.

* fix: use explicit pytorch index to prevent markupsafe wheel conflict

Configure the pytorch CPU index as explicit=true in pyproject.toml so it is
ONLY used for torch (via [tool.uv.sources]). All other packages (including
markupsafe) are resolved exclusively from PyPI, preventing the pytorch index
from serving incompatible cp314-only wheels for non-pytorch packages.

Remove UV_INDEX and UV_INDEX_STRATEGY from CI workflow (no longer needed
since the index is now configured in pyproject.toml).

* ci: trigger CI run

* ci: retry trigger

* ci: trigger after remote URL fix

* ci: add workflow_dispatch to unblock manual trigger

* fix: remove empty env blocks left after UV_INDEX removal

* fix: add type: ignore for optional claude_agent_sdk imports (macOS-only)

feat(retain): verbatim, chunks modes and named retain strategies (#593)
* feat(retain): add verbatim extraction mode

Adds retain_extraction_mode="verbatim" that stores each chunk as-is
without LLM summarization. The LLM still runs to extract entities,
temporal info, and location for full indexability — only the fact text
is replaced with the original chunk content (one memory per chunk).

Useful for RAG-style indexing and benchmarks where original text
must be preserved in memory.

- Add "verbatim" to RETAIN_EXTRACTION_MODES in config.py
- Add VERBATIM_FACT_EXTRACTION_PROMPT with instructions to preserve text
- Add _collapse_to_verbatim() post-processing to enforce 1 fact/chunk
- Expose in bank config UI dropdown with updated description
- Update configuration.md docs with verbatim mode description
- Add unit test for _collapse_to_verbatim and integration test via LLM
- Fix pre-existing main.py CLI override missing new reranker fields
- Fix pre-existing cross_encoder.py ty type error via setattr

* refactor(retain): verbatim mode skips 'what' field entirely

Instead of asking the LLM to echo the chunk text back into 'what' and
then discarding it, verbatim mode now uses a dedicated schema
(VerbatimExtractedFact) that omits the 'what' field altogether.
The LLM only returns metadata (entities, temporal info, location, who),
saving output tokens and avoiding any risk of paraphrasing before the
backfill.

- Add VerbatimExtractedFact / VerbatimFactExtractionResponse models
- Verbatim mode skips causal-relations section (nothing to relate causally)
- _extract_facts_from_chunk: allow missing 'what' in verbatim mode,
  set combined_text="" (backfilled by _collapse_to_verbatim)
- Update verbatim prompt to say DO NOT include 'what'

* feat(retain): add index_only extraction mode

Zero-LLM retain mode: chunks are stored as-is with no LLM call, no
entity extraction, and no temporal indexing. Embeddings still run for
semantic search. User-provided entities via RetainContent.entities
are the sole source of entity data.

Early return placed before the batch-API check so no LLM queue or
concurrency locks are acquired.

- Add "index_only" to RETAIN_EXTRACTION_MODES
- Add _extract_facts_index_only() with pure Python chunking path
- Add to UI dropdown and update description
- Update configuration.md with index_only docs and table entry
- Add unit test asserting zero token usage and exact text preservation

* feat(retain): add named retain strategies

Allows mixing extraction modes in a single bank via named strategies.
Each strategy is a set of hierarchical config overrides (extraction_mode,
chunk_size, entity_labels, entities_allow_free_form, etc.) applied on
top of the resolved bank config at retain time.

- retain_strategies: dict of strategy_name → config overrides (bank config)
- retain_default_strategy: default strategy when none specified (bank config)
- strategy field on /retain request: per-call override
- apply_strategy() in config_resolver applies overrides via dataclasses.replace()
- strategy propagates through retain_batch_async → _retain_batch_async_internal
  and through the async worker task payload
- Any hierarchical field is overridable per strategy, including entity_labels
  and entities_allow_free_form
- Docs updated with strategy configuration example and RRF fairness note
- Unit test for apply_strategy covering overrides, unknown strategy, and
  non-hierarchical field filtering

* feat(retain): add per-item strategy and strategy tests

- Add `strategy` field to `MemoryItem` so individual items in a retain
  request can override the request-level strategy
- Add `strategy` field to `FileRetainMetadata` for per-file strategy
  override in file retain requests
- Group memory items by effective strategy in `api_retain`; each group
  is processed as a separate batch, results are aggregated
- Thread strategy through `submit_async_file_retain` →
  `_handle_file_convert_retain` → retain task payload
- Add `operation_ids` to `RetainResponse` for async requests with
  mixed per-item strategies
- Add `test_strategy_overrides_extraction_mode_for_index_only`: unit
  test verifying a named strategy with index_only bypasses the LLM
- Add `test_retain_request_per_item_strategy_field`: unit test for
  per-item strategy grouping logic

* feat(ui): add retain strategies and default strategy to bank config UI

- Add StrategiesEditor component: per-strategy cards with name input and
  JSON overrides textarea; supports add/remove; validates JSON inline
- Add Default Strategy text input (retain_default_strategy)
- Update RetainEdits type and retainSlice() to include both new fields
- Regenerate OpenAPI spec (retain_strategies, retain_default_strategy,
  per-item strategy on MemoryItem/FileRetainMetadata, operation_ids on
  RetainResponse)

* refactor(ui): move retain strategies into its own dedicated config section

* feat(ui): improve retain strategies UX and add strategy to document dialog

- Strategy form now includes entity section (free form toggle + entity labels editor)
- Default strategy selector moved outside tab panel, above strategy chips
- Strategy tabs redesigned with underline indicator style for clarity
- Remove strategy confirms with AlertDialog
- Fix tab re-render bug when typing strategy name (skipSyncRef)
- Add strategy field to Add New Document dialog (text + per-file for uploads)
- File upload collapsible uses same Document/Tags/Source tabbed layout
- API: validate empty strategy names in config_resolver
- api.ts: add strategy field to retain and uploadFiles types

* fix: forward strategy through HTTP layer and SDK; add integration test

- route.ts: extract and forward `strategy` from request body to retainBatch
- TypeScript SDK: accept and forward `strategy` in retainBatch options and per-item
- config_resolver.py: validate empty strategy name keys on update

- Regenerate OpenAPI spec to include strategy field in RetainRequest and MemoryItem
- Regenerate TypeScript client from updated spec
- Add strategy to MemoryItemInput interface
- Remove (item as any) cast now that strategy is properly typed

* rename: index_only extraction mode → chunks

* remove top-level strategy from RetainRequest; strategy is per-item only

* fix(clients): update Go and Python generated clients with strategy/operation_ids fields

* fix(ci): update hierarchical field count, add strategy to Rust MemoryItem initializers

* fix(go-client): minimal targeted YAML updates for strategy/operation_ids fields

docs: add config vars for local reranker FP16 and bucket batching (#589)
* docs: add config vars for local reranker FP16 and bucket batching (#588)

* fix: add missing reranker local fields to CLI config override and fix ty type error

- Add reranker_local_fp16, reranker_local_bucket_batching, reranker_local_batch_size
  to the manual HindsightConfig() constructor call in main.py (CLI override block)
- Replace direct module attribute assignment with setattr() in the transformers 5.x
  monkey-patch so ty can resolve it without raising unresolved-attribute

feat: local reranker FP16, bucket batching, and transformers 5.x compatibility (#588)
Three independent, cumulative improvements to LocalSTCrossEncoder:

1. transformers 5.x compatibility patch for XLM-RoBERTa models (Jina v2)
2. FP16 inference (opt-in via HINDSIGHT_API_RERANKER_LOCAL_FP16)
3. Length-sorted bucket batching (opt-in via HINDSIGHT_API_RERANKER_LOCAL_BUCKET_BATCHING)

All behind .env switches with conservative defaults preserving current behavior.

Fixes #586, Closes #587

fix(migration): backsweep orphaned observation memory units (#584)
* fix(migration): backsweep orphaned observation memory units

Delete observation rows whose every source_memory_id points to a
deleted memory unit, left behind before PR #580 fixed the chunk FK
cascade and before delete_document() called
_delete_stale_observations_for_memories.

Closes #572 (data cleanup for pre-existing installs).

* fix(migration): broaden backsweep to cover all fact types and bank-level orphans

- Pass 1: delete any memory_units row (all fact_types) whose bank_id no
  longer exists in banks — catches orphans from bank deletions that
  predate a FK cascade between the two tables.
- Pass 2: delete observation rows whose every source_memory_id points to
  a deleted memory unit, regardless of document_id/chunk_id anchors.

* test(migration): verify backsweep removes orphans and preserves legit rows

Adds a focused migration test that:
- Starts a fresh pg0 instance at revision f6g7h8i9j0k1
- Seeds orphaned rows for both backsweep passes (ghost-bank + all-dead-sources)
- Seeds legitimate rows that must survive
- Applies the backsweep migration to head
- Asserts the expected rows are deleted/preserved

fix: change chunk FK to CASCADE so doc deletion removes linked memory units (#580)
The foreign key from memory_units.chunk_id to chunks.chunk_id used
ON DELETE SET NULL, which left ghost memory_units rows (chunk_id nulled
out, no parent document) after a document was deleted.  Switching to
ON DELETE CASCADE lets the existing document -> chunks -> memory_units
cascade clean up everything in one pass.

Closes #572

fix: inject Accept header in MCP middleware to prevent 406 errors (#571)
Some MCP clients (e.g., Claude Code) don't send an Accept header,
causing the MCP SDK to reject requests with 406 Not Acceptable. The
middleware now ensures Accept includes application/json and
text/event-stream when missing.

fix: support gemini-3.1-flash-lite-preview by preserving thought_signature in tool calls (#568)
Gemini 3.1+ thinking models include a thought_signature field in functionCall
parts. When reconstructing conversation history for subsequent turns, this
signature must be preserved or the API returns 400 INVALID_ARGUMENT.

- Add optional thought_signature field to LLMToolCall
- Capture thought_signature from Gemini response parts
- Pass thought_signature back when reconstructing multi-turn history
- Add gemini-3.1-flash-lite-preview to the LLM provider test matrix

feat: compound tag filtering via tag_groups (#562)
* feat: add compound tag filtering via tag_groups

Adds tag_groups to RecallRequest and ReflectRequest to express arbitrary
boolean tag predicates: leaf {tags, match}, and/or/not compounds.
Top-level groups are AND-ed. Existing tags/tags_match unchanged.

Examples:
  Step filter AND user scope:
    tag_groups: [{tags: ["step:5","step:8"], match: "any_strict"},
                 {tags: ["user:alice"], match: "all_strict"}]
  Exclusion:
    tag_groups: [{tags: ["user:alice"], match: "all_strict"},
                 {not: {tags: ["archived"], match: "any_strict"}}]

- Recursive SQL builder (build_tag_groups_where_clause) threads through
  all 4 retrieval strategies (semantic/BM25, temporal, graph, MPFP)
- Python-side filter (filter_results_by_tag_groups) for post-traversal
- 22 new unit tests
- OpenAPI spec + all clients regenerated (Rust, Python, TypeScript, Go)

* fix: add tag_groups: None to Rust CLI struct initializers

* fix: add tag_groups: None to Rust client test RecallRequest initializer

* feat: reject tags+tag_groups together, add tag_groups integration tests

- Add model_validator to RecallRequest and ReflectRequest that returns 422
  when both `tags` and `tag_groups` are set (mutually exclusive)
- Add 5 integration tests for tag_groups compound filtering:
  * validation: 422 when both fields are set
  * AND filter: two leaf groups (step scope AND user scope)
  * OR compound: user:alice OR user:bob
  * NOT compound: user:alice AND NOT archived
  * Nested: user:alice AND (step:5 OR step:8)

* ci: trigger CI run

fix: remove broken minimax test and enhance slim smoke test with retain/recall (#564)
- Delete test_minimax_provider.py which imports non-existent `create_llm`
  function (should be `create_llm_provider`), causing pytest collection errors
- Add scripts/smoke-test-slim.sh: shared retain + recall validation script
  used by both Docker slim and pip slim CI jobs
- Update docker/test-image.sh to run retain/recall after health check for
  all API targets
- Update test-pip-slim CI job to run the shared smoke test script

feat: introduce hindsight-api-slim and hindsight-all-slim packages (#560)
* feat: introduce hindsight-api-slim and hindsight-all-slim packages

Closes #552

- Move all source code from hindsight-api/ to new hindsight-api-slim/
- hindsight-api-slim has heavy ML deps (torch, sentence-transformers,
  transformers, einops, flashrank, mlx, mlx-lm, safetensors) and
  pg0-embedded as optional extras: [local-ml], [embedded-db], [all]
- hindsight-api becomes a zero-code meta-package depending on
  hindsight-api-slim[all] for full backward compatibility
- Add hindsight-all-slim meta-package: hindsight-api-slim + client + embed
- hindsight-all updated to depend on hindsight-api-slim[all]
- pg0.py: lazy-import pg0 with clear ImportError pointing to [embedded-db]
- Dockerfile: replace sed hack with proper uv sync --extra flags
- Update release.yml, test.yml, lint.sh, release.sh, CLAUDE.md and
  all path references throughout the repo

* refactor: rename hindsight/ directory to hindsight-all/

* docs: document hindsight-api-slim and hindsight-all-slim package variants

Add package variants table and extras explanation to installation.md

* docs: remove emojis from installation.md, use professional tone

* docs: link Docker slim variant to pip package variants section

* docs: consolidate Docker image variants into single table

* ci: fix working-directory paths after package restructure

- Replace all hindsight-api → hindsight-api-slim in test.yml
- Replace hindsight → hindsight-all in test.yml
- Add --extra embedded-db to test-embed API install step

* ci: add local-ml and embedded-db extras to API sync steps

These extras were previously implicit in the old hindsight-api package
(which bundled everything). Now that hindsight-api-slim uses optional
extras, we must explicitly request local-ml and embedded-db in CI.

* ci: add API install step with embedded-db to test-embed smoke test

The smoke test starts hindsight-api as a daemon, which requires pg0-embedded.
Add a dedicated install step for hindsight-api-slim with embedded-db extra
so the daemon can start successfully.

* ci: remove --no-install-project when using optional extras

When --no-install-project is combined with --extra, the optional deps
are not installed because extras require the project to be active.
Remove --no-install-project from steps that need local-ml or embedded-db.

* ci: fix ordering of uv sync steps to preserve optional extras

When uv sync runs for a different workspace member, it removes optional
extras installed for other members. Fix by always running extra-requiring
API sync last, after other workspace member syncs.

Also remove --no-install-project from embedded-db sync in test-embed,
as --no-install-project prevents optional extras from being active.

* ci: add local-ml extra to test-embed API install for smoke test

The smoke test starts the full API server which needs sentence-transformers
for local embeddings (default provider). Add local-ml extra to the install.

* ci: simplify extras with --all-extras and add slim pip smoke test

- Replace explicit --extra local-ml --extra embedded-db with --all-extras
  for cleaner, more maintainable sync steps
- Add test-pip-slim job: tests hindsight-api-slim[embedded-db] without
  local ML models, using Cohere for embeddings/reranking (mirrors Docker
  slim smoke test approach)

* ci: simplify slim smoke test to health check only (mirrors Docker test)
