* feat: expose document_metadata in API and control plane
Add document_metadata (sourced from retain_params.metadata) to both
list and get document endpoints. Display it in the control plane
documents table and detail panel. Drop the unused metadata column
from the documents table (was always stored as empty {}).
* fix: code review fixes for document_metadata feature
- Remove unnecessary `import json as _json` (json already imported at module level)
- Simplify redundant truthiness checks in retain_params parsing
- Regenerate OpenAPI spec and client SDKs (Python, TypeScript, Go)
- Add tests for document_metadata in get_document and list_documents
* feat(ui): improve documents table and detail panel
- Relative timestamps with full date on hover
- Remove context column from table
- Metadata shown as k=v badges (blue, like tags)
- Size in bytes instead of chars
- Document IDs wrap instead of truncating
- Detail panel wider (560px)
- Retain params: context, event_date, metadata badges
The installer skipped settings.json entirely if it already existed,
leaving version and new config keys stale. Now merges: updates version,
adds new upstream keys, preserves user customizations.
Also fixes pre-existing typo: RERANK_URL → rerank_url in ZeroEntropy
cross-encoder.
* refactor(llamaindex): merge two packages into single hindsight-llamaindex
Merge `llama-index-tools-hindsight` and `llama-index-memory-hindsight` into

- Move HindsightToolSpec and HindsightMemory into the same package
- Delete `llamaindex-memory/` directory
- Add CI test job for llamaindex integration
- Update docs, blog post, and integrations.json
* fix(blog): update llamaindex blog post for merged package
- Move date to 2026-03-30

- Rename "OpenAI Codex CLI" to "Codex" in integrations.json and docs
- Use openai.png icon for Codex integration
* feat(api): add duration_ms to audit log entries
Server-computed duration in milliseconds (started_at → ended_at) on
the list audit logs endpoint. Null when ended_at is not set.
Closes#749
* feat(api): add duration_ms to audit log entries and type audit endpoints
- Add server-computed duration_ms (started_at → ended_at) to audit log
list response. Null when ended_at is not set.
- Add typed Pydantic response models for both audit log endpoints
(list and stats) so they appear in the OpenAPI spec.
- Regenerate OpenAPI spec and all client SDKs.
Closes#749
* chore: regenerate docs skill after audit log response models
* fix(codex): cleanup dead code and add to release lifecycle

- Add settings.json version fallback to release script
- Add codex CI test job in test.yml
- Add codex to integrations.json registry
* docs(codex): add changelog page and link from integration docs
* feat(codex): add hosted installer script (get-codex)
Add self-contained installer at hindsight.vectorize.io/get-codex that
downloads scripts from GitHub, configures hooks, and supports local/cloud
mode selection — no git clone required.
Update docs and README to use the one-liner install:
curl -fsSL https://hindsight.vectorize.io/get-codex | bash
* chore(codex): remove install.sh in favor of hosted get-codex
* fix(docs): use /next/ prefix for codex changelog link

- Add AG2 integration doc with quick start, configuration, GroupChat example, and API reference
- Add to sidebar, versioned sidebar, and integrations hub
- Add AG2 icon
* feat: add audit log for feature usage tracking
Add full auditability for all mutating and core API operations across
HTTP, MCP, and system (worker) transports. Audit entries record raw
request/response as JSONB, timing (started_at/ended_at), action, and
transport type.
Backend:
- New audit_log table with JSONB columns for expandability without
future migrations (merge migration of 3 existing heads)
- AuditLogger with fire-and-forget writes via asyncio.create_task
- @audited decorator on 28 HTTP route handlers
- MCP tool audit wrapping for 16 auditable tools
- Worker task execution wrapped with audit_context
- List endpoint with action, transport, date range filters + pagination
- Stats endpoint with per-day counts for charting
- Configurable retention sweep (concurrent-safe DELETE)
Config (env-only, static):
- HINDSIGHT_API_AUDIT_LOG_ENABLED (default: false)
- HINDSIGHT_API_AUDIT_LOG_ACTIONS (comma-separated allowlist, empty=all)
- HINDSIGHT_API_AUDIT_LOG_RETENTION_DAYS (default: -1, keep forever)
Control Plane:
- New "Audit Logs" tab on bank configuration page
- Line chart showing request volume (today/7d/30d) with action filter
- Filterable table with action, transport, date range filters
- Paginated list with detail dialog showing raw request/response JSON
Tests:
- 13 tests covering list, filters, pagination, stats, disabled mode,
action allowlist, and ordering
* fix: split 3-way merge migration into two 2-way merges
Alembic doesn't support 3-parent merge migrations. Split into a no-op
merge of 2 heads (b1c2d3e4f5g6) followed by the audit_log table
migration merging the third head.
* fix: correct merge migration to merge actual 2 heads
The original analysis incorrectly identified 3 heads. There were only 2
(a3b4c5d6e7f8 and c8e5f2a3b4d1). Remove the unnecessary intermediate
merge migration and fix the audit_log migration to merge these 2 heads.
* fix: use 'heads' instead of 'head' in migration runner
Alembic's upgrade('head') fails when multiple heads exist (e.g. from
namespace package overlaps between hindsight-api and hindsight-api-slim).
Using 'heads' (plural) handles this gracefully by upgrading all branches.
* chore: regenerate OpenAPI spec with audit log endpoints
* chore: regenerate TypeScript client and docs skill OpenAPI spec
Python and Go clients still need regeneration (requires Docker).
* chore: regenerate all client SDKs (Python, Go, TypeScript)
Adds generated audit log API clients for Python (audit_api.py),
Go (api_audit.go), and TypeScript client type updates.
FastAPI generates the ValidationError schema with only loc, msg, and
type, but Pydantic v2 actually returns input, ctx, and url as well.
Generated clients with strict JSON decoding (Go's DisallowUnknownFields)
cannot parse real 422 responses — the actual validation message gets
replaced by a confusing JSON decoding error.
- Patch the OpenAPI schema in create_app() to add input, ctx, url
- Regenerate spec and Go client

* 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
* feat: add Agno integration with Hindsight memory toolkit
Add hindsight-agno package providing Hindsight memory tools (retain,
recall, reflect) as an Agno Toolkit, following the same pattern as
Agno's Mem0Tools. Includes per-user bank isolation, global config,
bank auto-creation, and memory_instructions() for system prompt
injection.
Also adds cookbook documentation page with architecture diagrams,
quick start examples, and configuration reference.

* 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)
* fix: correct type: ignore rules for claude_agent_sdk and fix utcnow deprecation
* 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
- bank-config-view.tsx: merge entity fields into RetainStrategyForm, redesign strategy tabs with underline style, add confirmation dialog for removal, fix tab-reset-on-typing with skipSyncRef, move default strategy selector outside panel
- bank-selector.tsx: add strategy field to Add Document dialog (per-file in tabbed collapsible)
- test_retain.py: add end-to-end integration test verifying named strategy application (index_only = 0 LLM tokens)
* fix: regenerate TypeScript client with strategy field in RetainRequest/MemoryItem
- 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
* feat: add hindsight-hermes integration for Hermes Agent
* chore: add Hermes docs page, icon, and release process bindings
- Add cookbook page for Hermes integration (synced with README)
- Add Hermes icon and map hindsight-hermes SDK tag in CookbookGrid
- Add cookbook entry to index.mdx
- Add hindsight-hermes to release.sh PYTHON_PACKAGES array
- Add build, publish, artifact upload, and release asset steps in release.yml

* 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
* docs: revamp sidebar with icon grid components and language support

- Regenerate OpenAPI spec and all SDK clients
* fix: update Rust CLI list_operations call with new type parameter
* feat: add update document tags endpoint with observation invalidation
Adds PATCH /v1/default/banks/{bank_id}/documents/{document_id} to change
tags on a document without re-processing content.
- Updates tags on the document and all associated memory units atomically
- Invalidates observations derived from the document's memory units
- Resets consolidated_at on the document's own units for re-consolidation
- Also resets consolidated_at on co-source memories from other documents
that shared those observations (matching delete_document behavior)
- Triggers async consolidation when observations are invalidated
- 9 new tests covering all invalidation scenarios
UI: adds inline tag editor to the document detail panel in the control plane
Docs: new "Update Document Tags" section in documents.mdx with Python/JS examples
* refactor: simplify UpdateDocumentTagsResponse to {success: true}
* refactor: make PATCH /documents generic update_document endpoint
Renames update_document_tags → update_document (engine + HTTP + clients + UI).
Currently only tags are supported; the structure is open for future fields.
Tags are the only field with side effects (observation invalidation + re-consolidation).

* feat: mental model refresh history tracking and UI diff view
- DB migration: add history JSONB column to mental_models table
- Track previous content on each refresh in update_mental_model
- Add get_mental_model_history() engine method
- New GET /mental-models/{id}/history endpoint
- Control plane proxy route and getMentalModelHistory() in api.ts
- MentalModelDetailModal: add History tab with lazy loading, carousel
navigation (left=older, right=newer), word-level content diff view
* fix: resolve alembic migration head conflict for mental model history
* feat: mental model history tracking, side-by-side diff UI, and config flag
- Track content changes on every mental model update/refresh (persisted in JSONB history column)
- New GET /mental-models/{id}/history endpoint returning changes most-recent-first
- Side-by-side diff view in History tab (Before/After columns, line-level highlights)
- Actions dropdown in detail panel (Edit, Refresh, View History, Delete)
- HINDSIGHT_API_ENABLE_MENTAL_MODEL_HISTORY config flag (default: true)
- Also adds missing HINDSIGHT_API_ENABLE_OBSERVATION_HISTORY to configuration docs
- Python client wrapper method get_mental_model_history()
- Tests for history persistence (recorded, ordered, name-only skipped, missing returns None)
- Fix NameError: timezone not imported in update_mental_model
* fix: call get_mental_model_history before delete in doc example
* feat: add source facts token limits to consolidation and recall
- Add two new configurable (per-bank) parameters:
- consolidation_source_facts_max_tokens: total token budget for source
facts across all observations in the consolidation prompt (-1 = unlimited)
- consolidation_source_facts_max_tokens_per_observation: per-observation
cap so each observation gets a fair share of source facts (-1 = unlimited,
default 256)
- Both are also exposed as recall API parameters via SourceFactsIncludeOptions
(max_tokens and max_tokens_per_observation)
- Consolidation now uses resolve_full_config to respect bank-level overrides
- Improve consolidation prompt: temporal metadata (occurred_start=, | Involving:)
is now clearly separated from observation text, with a concrete example showing
the expected synthesis style and explicit rules not to copy raw fact lines
- Add tests for recall source facts capping and consolidation config forwarding
- Expose all three new fields in the control plane bank config UI
- Document new env vars in configuration.md
- Regenerate OpenAPI spec and all SDK clients
* fix: reorder observations UI fields and rename Label Groups to Entity Labels
* fix: revert Entities section title (only rename inner label)
* doc: add consolidation source facts and batch size fields to memory-banks docs
* feat: add observation history tracking and UI diff view
- Track observation changes over time in a JSONB history column,
appending each update's previous state (text, tags, dates, sources)
instead of overwriting
- Add HINDSIGHT_API_ENABLE_OBSERVATION_HISTORY config flag (default: true)
to toggle history recording
- Expose history field in get_memory_unit for observations
- Fix observations/[modelId] route that was proxying to wrong endpoint
- Add History tab in observation modal and History section in panel,
showing word-level and tag diffs between each change (newest first)
- Extract shared ObservationHistoryView component used by both modal and panel
- Add --random-port flag to start.sh to run multiple dev instances
- Scope Next.js distDir by port to prevent lock file collisions between instances
- Restyle consolidation pending badge (rounded-md with border) and add
inline refresh button; fix loading flicker on data refresh
* feat: dedicated observation history endpoint with source facts diff
- Add GET /memories/{id}/history endpoint returning enriched history with
resolved source fact texts and is_new flags per change
- Deprecate history field in GET /memories/{id} (always returns empty list)
- Reconstruct cumulative source facts per history entry by working backwards
from current state, marking newly added facts with is_new
- Replace inline history panel with "View History" button opening modal
- History modal fetches from dedicated endpoint lazily on tab switch
- Timeline view now opens MemoryDetailModal instead of side panel
- History view uses prev/next navigation (left = older, right = newer)
- Fix --random-port: pass dynamic API_PORT as HINDSIGHT_CP_DATAPLANE_API_URL
to control plane, preserving caller values over .env
