-### API Layer & Data Access
-- **No direct database access in `api/http.py`** (or any API router). HTTP handlers must not build SQL, call `acquire_with_retry` / `conn.fetch` / `conn.fetchrow` / `conn.execute`, or reference `fq_table(...)`. All persistence and queries live in `MemoryEngine` (the engine layer). A handler parses/validates the request, calls an engine method, shapes the HTTP response, and maps domain results to status codes (e.g. a `None` return → 404).
-- **Authentication/tenancy is enforced inside each engine method, not assumed by the handler.** Every engine method that touches bank-scoped data must authenticate via `request_context` — typically `await self._authenticate_tenant(request_context)` (often indirectly through `get_bank_profile(...)`) — so the correct tenant schema is resolved before any query runs. Handlers must thread `request_context` through to the engine method; never query a tenant-scoped table assuming the schema is already set.
-- Engine methods return typed models (Pydantic/dataclass), not raw dicts (see Type Safety).

 ### Branch Hygiene
 - **Always start new feature branches from `origin/main`** — rebase to ensure a clean base.

Flag these as findings:
-- A prompt/classification change verified only by MockLLM or string assertions (MockLLM echoes input — such tests pass spuriously). **Should fix.**
-- A test that hard-asserts `fact_type == "world"/"experience"` (or other model-decided output) instead of judging it — non-deterministic, will flake across providers/runs. **Should fix** (move the classification check into the judge `criteria`; keep only genuinely deterministic structural asserts direct).
-- Deterministic mechanics (prompt assembly, suppression/branching logic) that are covered *only* by a slow LLM test — these should also have fast non-LLM unit tests. **Note.**

Flag any integration that is released (or being released) but missing from `integrations.json`, and any JSON entry without a doc page.

----
-
-# Hindsight Release
-
-Cut a **core** Hindsight release and open the accompanying changelog/blog PR. This is for the core
-product version (API, clients, CLI, control plane, Helm). **Integrations are versioned
-independently** — use `scripts/release-integration.sh` for those, not this skill.
-
-The release is **irreversible and outward-facing**: it tags a version and pushes it straight to
-`main`, which triggers CI that publishes packages to PyPI / npm / Helm. Confirm the version number
-and that the intended fixes are already merged to `main` before you start.
-
-## Step 0 — Pre-flight
-
-1. **Decide the base.** A release is cut from the latest `origin/main`, never from a feature
-   branch. `git fetch origin --tags` first. Confirm the "couple of fixes" the user means are
-   actually merged to `main` (`git log v<prev>..origin/main --oneline`).
-2. **Find where `main` is checked out.** `main` is often already checked out in a sibling worktree
-   (`git worktree list`). You **cannot** check out `main` in a second worktree — run the release in
-   the worktree that already holds it. If that worktree is dirty with throwaway cruft
-   (`.next-*` tsconfig paths, screenshots), `git stash push -u`, fast-forward to `origin/main`,
-   run the release, then `git stash pop`.
-3. **Pitfall:** never pipe the checkout in an `&&` chain like
-   `git checkout main 2>&1 | tail && git reset --hard ...` — the pipe's exit status is `tail`'s
-   (always 0), so a failed checkout won't stop the chain and the `reset` fires on the **wrong
-   branch**. Check out as its own command and verify `git branch --show-current` before resetting.
-
-## Step 1 — Cut the release
-
-Run from the worktree on a clean `main`:
-
-```bash
-./scripts/release.sh <version>     # e.g. 0.8.1  (no leading v)
-```
-
-`release.sh` bumps the version in every component, regenerates the OpenAPI spec + all client SDKs,
-updates docs versioning, commits `Release v<version>`, tags `v<version>`, and **pushes the commit
-and tag directly to `main`**. The push triggers the `Release` GitHub Actions workflow that builds
-and publishes the packages. It is **not** a PR.
-
-Verify after: `gh run list --limit 5` should show the `Release v<version>` workflow running, and
-`git ls-remote --tags origin v<version>` should return the tag.
-
-## Step 2 — Changelog + blog PR (separate)
-
-Done **after** the tag exists, as its own PR (precedent: v0.8.0 = #2053, v0.8.1 = #2080). Work on a
-branch off the new `main`:
-
-```bash
-git checkout -b docs-changelog-<version> origin/main
-```
-
-Only spin up a separate worktree (`git worktree add ../hindsight-changelog-<version> -b
-docs-changelog-<version> origin/main`) if you can't get a clean checkout otherwise — e.g. `main` is
-held in another worktree and the current one has work you don't want to disturb.
-
-**Branch naming:** use the `docs-` (hyphen) convention, e.g. `docs-changelog-0.8.1`. A remote
-branch literally named `docs` exists, so any `docs/...` branch is rejected on push with
-`directory file conflict`.
-
-### Changelog
-
-```bash
-uv run --directory hindsight-dev generate-changelog <version>
-```
-
-LLM-summarizes the commits between the previous tag and `v<version>` and prepends an entry to
-`hindsight-docs/src/pages/changelog/index.md`. Requires `OPENAI_API_KEY` (already in the repo
-`.env`). It excludes `hindsight-integrations/` source, but new integrations whose commits also
-touched docs will still appear — that matches precedent, leave them in the **changelog**.
-
-### Blog post
-
-Hand-write `hindsight-docs/blog/YYYY-MM-DD-version-X-Y-Z.md` (mirror an existing one; patch
-releases are short — see `2026-06-02-version-0-7-2.md`). Guidance:
-
-- **Explain user impact, not internals/mechanism.** Lead with what the user can now do and what to
-  set. Config/env-var names are fine (developer-facing), code symbols and internals are not.
-- **Do not list integrations in the release blog.** The core blog covers core engine / API /
-  ops changes; each integration ships its own changelog. (Integrations may still appear in the
-  generated `changelog/index.md` — that's fine; just keep them out of the blog.)
-- Call out an upgrade recommendation when there are operational/data-integrity fixes.
-- Validate formatting: `npx prettier --check <blog file>`.
-
-### Sync the docs skill
-
-```bash
-./scripts/generate-docs-skill.sh
-```
-
-Refreshes `skills/hindsight-docs/references/changelog/index.md`. It will also bump
-`skills/hindsight-docs/references/openapi.json` by one version — `release.sh` regenerates the skill
-*before* bumping OpenAPI, so the skill copy lags a version in the release commit; this step syncs
-it. Expect a one-line `version` diff there; keep it.
-
-### Commit, push, PR
-
-```bash
-git add -A
-git commit --no-verify -m "docs: changelog and blog post for v<version>"
-git push -u origin docs-changelog-<version>
-gh pr create --base main --title "docs: changelog and blog post for v<version>" --body "..."
-```
-
-Expected files in the PR: the changelog entry, the new blog post, the regenerated skill changelog
-mirror, and the skill `openapi.json` version sync.
-
-## Cleanup
-
-If you created a temporary worktree, remove it once the PR is up
-(`git worktree remove ../hindsight-changelog-<version>`; the branch stays on origin). Restore any
-stash you popped in Step 0.

 ### Adding Database Migrations

-migration file dispatches through `run_for_dialect`, which calls either

-Dead-code detection runs in CI (the `check-unused-code` job) at two levels:
-- **Blocking:** unused imports (ruff `F401`) and variables (`F841`) — `lint.sh` auto-removes
-  them and `verify-generated-files` fails on any leftover diff; and **knip** for orphaned
-  control-plane files / unused (or unlisted) `package.json` dependencies.

 **After completing any implementation work, run `/code-review`** to verify your changes against project standards (missing tests, dead code, type safety, etc.). Fix any "must fix" issues before considering the task done.
 
 **MANDATORY: Run `/code-review` before pushing code or creating a pull request.** Do not push or create a PR until all "must fix" issues are resolved.
 
-### Testing
-
-Most tests are deterministic (MockLLM, pure functions) — assert directly.
-
-**Tests that verify LLM behaviour use a real LLM + an LLM-as-judge.** When the thing under test is *how the model interprets a prompt* (classification, attribution, dimension preservation, instruction-following), MockLLM can't simulate it and exact string/enum asserts flake across providers and runs. Use this pattern instead:
-
-1. Mark the test module `pytestmark = pytest.mark.hs_llm_core` (single-provider; CI runs it in the core-LLM job). Use `hs_llm_mat` only for provider-matrix acceptance tests.
-2. Call the real pipeline (`LLMConfig.from_env()`, `_get_raw_config()`), e.g. `extract_facts_from_text(...)`.
-3. Assert with the judge, not string matching:
-   ```python
-   from tests.llm_judge import assert_meets_criteria
-   facts_summary = "\n".join(f"- [{f.fact_type}] {f.fact}" for f in facts)
-   await assert_meets_criteria(
-       response=facts_summary,
-       criteria="The first-person user statements are classified 'world' and attributed to the user, not the agent.",
-       context="What the input said and who was speaking.",
-   )
-   ```
-
-Rules of thumb:
-- **Judge anything non-deterministic** — including `fact_type` classification and speaker attribution. Do NOT hard-assert `fact_type == "..."`; pass a `[fact_type] fact` summary to the judge instead. Structural facts that ARE deterministic (counts, presence of a field, that a substring was injected into a prompt) stay as direct asserts in fast unit tests.
-- **Split the test surface**: cover the deterministic mechanics (prompt assembly, suppression logic) with fast non-LLM unit tests, and the model-following behaviour with one `hs_llm_core` judge test. (Example pair: `test_narrator_resolution.py` + `test_narrator_context_override.py`.)
-- The judge model is independent of the test provider (defaults to Gemini); never judge with the same call you're testing.

-# Hindsight with Claude Code (Claude Pro/Max subscription)
-
-Run Hindsight inside Docker using the `claude-code` LLM provider, backed by
-your host machine's Claude Pro or Max subscription credentials.
-
-The standalone Hindsight Docker image ships `claude-agent-sdk` but does **not**
-bundle the host `claude` CLI binary or any Claude credentials. This Compose
-file bind-mounts the host's CLI install and credentials into the container so
-the `claude-code` provider works without an API key.
-
-## When to use this
-
-- You have an active Claude Pro or Max subscription and want to use it for
-  Hindsight without paying separate Anthropic API costs.
-- You want a one-command `docker compose up` instead of a long `docker run`
-  invocation with many flags.
-- You are running on **Linux/amd64** — macOS Docker Desktop and Windows host
-  paths differ and are not yet covered (please open an issue if you'd like to
-  contribute a verified recipe for either).
-
-> **Personal-use only.**  Anthropic's
-> [Agent SDK documentation](https://docs.claude.com/en/api/agent-sdk/overview)
-> states that third-party developers should not offer claude.ai login or rate
-> limits for their products. Hindsight does **not** perform any login on your
-> behalf — it uses credentials you've already authenticated via
-> `claude auth login`. In January 2026, Anthropic
-> [enforced restrictions](https://paddo.dev/blog/anthropic-walled-garden-crackdown/)
-> against tools that spoofed the Claude Code client identity; Hindsight uses
-> the official Claude Agent SDK instead.
->
-> Do not deploy this configuration to shared environments or production. For
-> that, use the `anthropic` provider with an API key from the
-> [Anthropic Console](https://console.anthropic.com/). Usage counts against
-> your Claude Pro/Max subscription limits.
-
-## Prerequisites
-
-- Host has `claude` CLI installed (e.g., `npm install -g @anthropics/claude-code`)
-  and `claude auth login` has been run successfully.
-- `~/.claude.json` and `~/.claude/.credentials.json` exist on the host.
-- Host `claude` CLI version is **2.1.128 or newer** — the version bundled with
-  `claude-agent-sdk` 0.5.x has a protocol incompatibility in containers, so
-  the recipe overrides it with the host binary.
-
-## Quick start
-
-```bash
-# Set your host UID/GID (defaults to 1000:1000 if unset)
-export HOST_UID=$(id -u)
-export HOST_GID=$(id -g)
-
-docker compose -f docker/docker-compose/claude-code/docker-compose.yaml up -d
-```
-
-- API: http://localhost:8888
-- Control Plane: http://localhost:9999
-
-## Post-setup (one-time)
-
-After the container starts for the first time, run these commands to fix
-permissions and symlink the host `claude` binary into `$PATH`:
-
-```bash
-# Make ~/.claude writable by your UID (the CLI writes session/project state)
-docker exec --user 0:0 hindsight-claude-code chown $(id -u):$(id -g) /home/hindsight/.claude
-docker exec --user 0:0 hindsight-claude-code chmod 755 /home/hindsight/.claude
-
-# Symlink the host claude binary into PATH
-docker exec --user 0:0 hindsight-claude-code \
-  ln -sf /home/hindsight/.local/share/claude/versions/2.1.128 /usr/local/bin/claude
-```
-
-If you set `CLAUDE_CLI_VERSION` to a version other than `2.1.128`, update the
-symlink path accordingly.
-
-## Notes on the bind-mount surface (every flag is load-bearing)
-
-- **Host `claude` binary required** — the image ships only `claude-agent-sdk`,
-  not the CLI itself.
-- **SDK bundled-binary override** — the override of
-  `claude_agent_sdk/_bundled/claude` works around a protocol issue in the
-  bundled v2.1.121 binary inside containers. Once `claude-agent-sdk` ships
-  with v2.1.128+ this override can be dropped. Set `CLAUDE_CLI_VERSION` to
-  match your installed version.
-- **Single-file credential mounts** — credentials are mounted as individual
-  `:ro` files rather than a whole-directory `:ro` mount of `~/.claude`,
-  because the CLI writes session/project state at runtime and a read-only
-  directory mount silently breaks it.
-- **`--user` / `user:`** — the `user: ${HOST_UID}:${HOST_GID}` pattern
-  requires `chmod 755 /home/hindsight`, which is built into the image since
-  v0.6.0 (see [#1481](https://github.com/vectorize-io/hindsight/issues/1481)).
-- **`~/.hindsight-docker` data directory** — the pg0 data bind mount must be
-  writable by your host UID (see
-  [#1483](https://github.com/vectorize-io/hindsight/issues/1483)).
-- **Verified** on `linux/amd64` against `ghcr.io/vectorize-io/hindsight:latest`
-  v0.5.6+.
-
-## Using a different Claude CLI version
-
-If your host has a `claude` version other than 2.1.128, set
-`CLAUDE_CLI_VERSION` before starting:
-
-```bash
-export CLAUDE_CLI_VERSION=2.2.0
-docker compose -f docker/docker-compose/claude-code/docker-compose.yaml up -d
-```
-
-Then update the post-setup symlink to match:
-
-```bash
-docker exec --user 0:0 hindsight-claude-code \
-  ln -sf /home/hindsight/.local/share/claude/versions/2.2.0 /usr/local/bin/claude
-```

-# Hindsight with Custom Local Models
-
-Example Docker Compose setup that builds a Hindsight image with **non-default
-local embedder and reranker models baked in at build time**.
-
-This is the recommended pattern for production when you use a non-default
-local model: the container registry caches model layers per node, pod
-startup is deterministic, and you don't need a model-cache PVC (or any
-runtime dependency on HuggingFace).
-
-## When to use this
-
-- You override `HINDSIGHT_API_EMBEDDINGS_LOCAL_MODEL` or
-  `HINDSIGHT_API_RERANKER_LOCAL_MODEL` to a non-default model.
-- You want pod startup to be deterministic and offline-capable.
-- You'd otherwise reach for a Helm `modelCache` PVC just to avoid
-  re-downloading models.
-
-If you're using the **default** local models, the published full image
-(`ghcr.io/vectorize-io/hindsight:latest`) already bakes them in — you don't
-need this example.
-
-If you're using **external** providers (TEI, OpenAI, Cohere, ...) for
-embeddings and reranking, use the slim image directly — no models are
-needed in the image.
-
-## Quick start
-
-```bash
-export OPENAI_API_KEY=sk-xxx
-
-docker compose -f docker/docker-compose/custom-models/docker-compose.yaml up --build
-```
-
-- API: http://localhost:8888
-- Control Plane: http://localhost:9999
-
-## Using your own models
-
-Override the build args to bake different models:
-
-```bash
-docker compose -f docker/docker-compose/custom-models/docker-compose.yaml build \
-  --build-arg EMBEDDER=your-org/your-embedder \
-  --build-arg RERANKER=your-org/your-reranker
-```
-
-Then update the matching `HINDSIGHT_API_EMBEDDINGS_LOCAL_MODEL` and
-`HINDSIGHT_API_RERANKER_LOCAL_MODEL` values in `docker-compose.yaml` so the
-runtime points at the same model IDs.
-
-## Verifying the models are baked in
-
-`docker-compose.yaml` sets `HF_HUB_OFFLINE=1` and `TRANSFORMERS_OFFLINE=1`
-so that any attempt to download a model at runtime fails loudly instead of
-silently re-downloading. If the container starts and serves recall queries
-with these set, the models are correctly baked in.
-
-You can also inspect the image directly:
-
-```bash
-docker run --rm --entrypoint sh hindsight-custom-models-hindsight \
-  -c 'ls ~/.cache/huggingface/hub/'
-```
-
-## Why not a model-cache PVC?
-
-The Helm chart exposes an optional `api.persistence.modelCache` PVC for
-caching downloaded models across pod restarts. Compared to baking models
-into the image:
-
-- A PVC adds storage cost — one PVC per worker replica with
-  `volumeClaimTemplates`.
-- `ReadWriteOnce` (the default) pins pods to a node.
-- The PVC needs lifecycle management on `helm uninstall` / `helm upgrade`
-  — without `helm.sh/resource-policy: keep` it is deleted on uninstall;
-  with it, storage keeps billing forever until manually cleaned up.
-- Pod startup still depends on HuggingFace being reachable on first run.
-
-Image layers, by contrast, are pulled once per node and cached for free by
-the container runtime, with no orphaned-storage cleanup story.

-# Hindsight with a local llama.cpp server sidecar
-
-Example Docker Compose setup that runs Hindsight against a **local
-llama.cpp server**, fully offline, with no external API key required.
-
-## Architecture
-
-```
-┌────────────┐  HTTP /v1/chat/completions  ┌──────────────────────────────┐
-│ hindsight  │ ──────────────────────────▶ │ llama.cpp server (sidecar)   │
-│ (API + CP) │                             │ ghcr.io/ggml-org/llama.cpp   │
-└────────────┘                             └──────────────────────────────┘
-```
-
-`llama.cpp` runs as its own container and exposes an OpenAI-compatible
-HTTP API. Hindsight talks to it via the standard `openai` LLM provider
-with `HINDSIGHT_API_LLM_BASE_URL` pointed at the sidecar.
-
-This pattern follows
-[*Hosting llama-server with Docker* (ServiceStack)](https://servicestack.net/posts/hosting-llama-server).
-
-### Why a sidecar and not the in-process `llamacpp` provider?
-
-Hindsight does ship an in-process `llamacpp` provider that spawns
-`llama-cpp-python`, but the **published `ghcr.io/vectorize-io/hindsight`
-image deliberately omits `llama-cpp-python`** to keep the image small and
-avoid bundling native inference libraries that most users don't need.
-Trying to set `HINDSIGHT_API_LLM_PROVIDER=llamacpp` against the published
-image fails with `ModuleNotFoundError: No module named 'llama_cpp'`.
-
-The sidecar approach side-steps that entirely: the official llama.cpp
-image is used as-is for inference, Hindsight is used as-is for memory.
-Clean separation, no derived images.
-
-## Quick start
-
-```bash
-docker compose -f docker/docker-compose/local-llm/docker-compose.yaml up
-```
-
-- API: http://localhost:8888
-- Control Plane: http://localhost:9999
-
-**First boot downloads ~3.5 GB** (Gemma 4 E2B Q4_K_M GGUF) into the
-`llama_models` named volume. Subsequent boots reuse it.
-
-Hindsight only starts after llama.cpp's `/health` endpoint reports
-healthy, so the API will appear "stuck" for a few minutes on the first
-run while the model downloads.
-
-## Using a different model
-
-Override the HuggingFace repo / file in `docker-compose.yaml`:
-
-```yaml
-environment:
-  LLAMA_ARG_HF_REPO: bartowski/Qwen2.5-7B-Instruct-GGUF
-  LLAMA_ARG_HF_FILE: Qwen2.5-7B-Instruct-Q4_K_M.gguf
-```
-
-Also update `HINDSIGHT_API_LLM_MODEL` on the `hindsight` service to a
-matching alias (the value is sent to llama-server as the OpenAI `model`
-field — llama-server is lenient about this but it shows up in logs).
-
-## GPU acceleration
-
-The default compose file targets CPU because not everyone has a GPU. On
-CPU, Gemma 4 E2B runs at ~2-3 tokens/sec — fine for a smoke test, but the
-retain pipeline (which makes several multi-hundred-token LLM calls per
-memory) will time out against Hindsight's default LLM timeout. **For any
-real use, run on a GPU.**
-
-### NVIDIA
-
-1. Switch the `llama` service image from `:server` to `:server-cuda`.
-2. Uncomment the `LLAMA_ARG_N_GPU_LAYERS: "999"` env var (offload all
-   layers to GPU).
-3. Uncomment the `deploy.resources.reservations.devices` block.
-4. Install the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html)
-   on the host.
-
-The compose file has all four spots marked with inline comments.
-
-### Apple Silicon / ROCm / Vulkan
-
-The official `ghcr.io/ggml-org/llama.cpp` image only ships CPU and CUDA
-variants. For Metal (Apple Silicon), ROCm (AMD), or Vulkan backends,
-build llama.cpp yourself with the appropriate flags and reference the
-image you build instead. Docker Desktop on macOS cannot pass through the
-host GPU to a Linux container in any case — for Apple Silicon, run
-llama-server directly on the host and only put Hindsight in Docker.
-
-## Caveats
-
-- llama.cpp's HTTP API is OpenAI-compatible but not 100% feature-parity.
-  Function/tool calling support depends on the chat template baked into
-  the GGUF; some retain/reflect flows may behave differently than against
-  a hosted OpenAI model.
-- Small GGUFs (~3 B params) are useful for smoke testing but will
-  underperform a hosted frontier model on retain quality. Use a larger
-  GGUF (7-13 B params) for production-quality memory.
-- The `llama_models` named volume persists the GGUF across `docker
-  compose down`/`up` so the model is downloaded once, not every restart.

-"""Process-level caps for native ML thread pools.
-
-OpenBLAS, OpenMP, and MKL each spawn a worker pool sized to the host CPU count
-the first time they are loaded (numpy pulls in OpenBLAS eagerly; torch and
-onnxruntime load their pools lazily on first inference). Hindsight already
-parallelizes at the request level via thread-pool executors (embeddings on the
-default executor, the reranker on its own pool), so these native intra-op pools
-oversubscribe the CPU: on a many-core host the process accumulates 100+ native
-threads, which inflates memory and, under contention, can degrade throughput.
-
-We bound each pool to ``_MAX_NATIVE_THREADS`` (or the available CPU count, if
-smaller). "Available" is the CPU budget actually granted to the process, not
-``os.cpu_count()``: in a CPU-limited container ``os.cpu_count()`` still reports
-the host's cores, so sizing pools by it oversubscribes the container's real
-quota — the exact failure mode this guards against. We therefore take the
-smallest of the CPU-affinity set, the cgroup CPU quota, and ``os.cpu_count()``.
-
-Every cap is applied with ``setdefault`` so an operator who has deliberately
-tuned one of these variables keeps their value. This must run *before* numpy,
-torch, or onnxruntime are imported — those libraries read the variables only at
-load time — which is why it is invoked at the very top of
-``hindsight_api/__init__.py``, ahead of the package's other imports.

-"""Add a composite index on memory_links(bank_id, link_type) (PostgreSQL).
-
-``bank_id`` was added to ``memory_links`` in ``c5d6e7f8a9b0`` precisely so that
-bank-scoped reads (e.g. the stats endpoint) could filter on the link table
-directly instead of joining ``memory_units`` — that JOIN took 18+ seconds on
-banks with millions of links. The column landed without an index, so every
-``bank_id = $1`` predicate still falls back to a sequential scan over the whole
-table.
-
-This adds the missing btree. It is composite on ``(bank_id, link_type)`` rather
-than ``bank_id`` alone because the hot query is the stats endpoint's
-``SELECT link_type, COUNT(*) ... WHERE bank_id = $1 GROUP BY link_type``: a
-``(bank_id, link_type)`` index serves that filter, grouping and count as an
-index-only scan, never touching the heap, whereas a ``bank_id``-only index would
-still have to read every matching row to recover ``link_type``. ``link_type`` is
-low-cardinality (only ``temporal``/``semantic``/``caused_by`` are written —
-entity edges were dropped in ``e9b2c7d1f3a4``), so the trailing column adds
-little to the index size while removing the heap fetch.
-
-The Oracle baseline (``o1a2b3c4d5e6``) already creates ``idx_ml_bank_id`` on
-``memory_links(bank_id)``; that single-column index already covers Oracle's
-bank-scoped filter, so the Oracle slot here is intentionally absent and only the
-PostgreSQL dialect gets the composite index.
-
-``memory_links`` can hold tens of millions of rows, so the index is built
-CONCURRENTLY to avoid taking a write lock on the table. CONCURRENTLY cannot run
-inside a transaction block, so the statement runs in an ``autocommit_block()``;
-``IF NOT EXISTS`` keeps it idempotent across retries and re-migrated tenant
-schemas. A CONCURRENTLY build interrupted partway (lock conflict, disk
-pressure, signal) leaves the index behind as *invalid*; ``IF NOT EXISTS`` would
-then skip over it forever, so the upgrade first drops any invalid leftover of
-this name before (re)creating it.

-"""Repair mental_models.subtype on databases stuck at m3rg3h3ad5f6
-
-Three production deployments reported `column "subtype" of relation
-"mental_models" does not exist` on `create_mental_model` even after their
-container reported `Database migrations completed successfully` and
-`alembic_version` advanced to `m3rg3h3ad5f6` (see issue #1553, #1553#1
-confirmations from @4Lienau and @khanhduyvt0101).
-
-Both `h3c4d5e6f7g8_mental_models_v4` and `d5y6z7a8b9c0_backfill_mental_models_subtype`
-were meant to ensure `subtype` exists, but on databases that came through the
-`reflections -> mental_models` rename chain *and* whose alembic_version
-advanced past `d5y6z7a8b9c0` along an alternate path during the divergent-heads
-reorganization, neither column-add actually fired. The result is a head-tagged
-database with a v3-shaped `mental_models` table missing six columns:
-``subtype``, ``description``, ``entity_id``, ``observations``, ``links``,
-``last_updated``.
-
-This migration sits at the current head (`m3rg3h3ad5f6`) so every affected
-deployment will pick it up on next container start. It mirrors the column-add
-block from `d5y6z7a8b9c0_backfill_mental_models_subtype` using
-``ADD COLUMN IF NOT EXISTS`` so it is a no-op on databases where the columns
-are already present.

-"""Make memory_links.from_unit_id and memory_links.to_unit_id FKs deferrable.
-
-Revision ID: 9f8e7d6c5b4a
-Revises: o1a2b3c4d5e6
-Create Date: 2026-05-03
-
-Background
-----------
-Concurrent retain (which INSERTs into ``memory_links``) and any code path
-that DELETEs a row whose deletion cascades into ``memory_links`` (e.g.
-delta-retain superseding chunks, which CASCADEs chunks → memory_units →
-memory_links) can deadlock under sustained single-tenant write load.
-
-The deadlock cycle:
-
-* Tx A: ``DELETE FROM chunks WHERE chunk_id = ANY(...)``
-  → CASCADE acquires row locks on memory_units, then on memory_links rows
-    where ``to_unit_id`` matches the deleted units.
-* Tx B: ``INSERT INTO memory_links (...)`` referencing one of the same
-  memory_units rows.
-  → The immediate FK check takes ``FOR KEY SHARE`` on those memory_units
-    rows.
-
-The two transactions take row locks on the same memory_units rows in
-opposite orders depending on which side started first. PostgreSQL detects
-the cycle and aborts one transaction; the loser is killed mid-batch, the
-winner continues. Workers then retry, but under sustained write load the
-pattern repeats.
-
-Fix
----
-Make both ``memory_links → memory_units`` FKs (``from_unit_id`` and
-``to_unit_id``) ``DEFERRABLE INITIALLY DEFERRED``. This pushes the FK
-check from INSERT time to COMMIT time:
-
-* INSERT no longer takes ``FOR KEY SHARE`` on the memory_units row → no
-  contention with the cascading DELETE's row lock.
-* At COMMIT the engine validates referential integrity in one shot. If a
-  cascade-DELETE has since removed the referenced unit, the INSERT
-  transaction commits OR fails with a clean FK violation (sqlstate
-  23503) instead of a deadlock (sqlstate 40P01).
-
-The ``WHERE EXISTS`` filter already in ``_bulk_insert_links`` continues to
-filter out the typical "stale unit_id" case at INSERT time; the deferred
-FK is only the backstop for the narrow race window between the EXISTS
-probe and COMMIT. ``ON DELETE CASCADE`` semantics are unchanged — only
-the *timing* of the constraint check moves.
-
-The ``entity_id`` FK on ``memory_links`` is not changed; entities are not
-involved in the observed deadlock cycle and leaving the constraint
-immediate keeps the error message specific when an entity row is missing.

-"""Repair: widen the remaining live ``bank_id`` columns from VARCHAR(64) to TEXT on PostgreSQL.
-
-Follow-up to ``c3e5a7b9d1f4`` (issue #2106), which widened the two *history*
-tables (``observation_history``, ``mental_model_history``) to ``TEXT`` after the
-narrow ``VARCHAR(64)`` declaration bricked startup. The same VARCHAR(64) / TEXT
-inconsistency still affects the live tables that store a user-supplied
-``bank_id``:
-
-* ``directives``    -- created VARCHAR(64) in ``p1k2l3m4n5o6``
-* ``mental_models`` -- VARCHAR(64) (origin ``pinned_reflections`` in
-                       ``n9i0j1k2l3m4``; recreated in ``h3c4d5e6f7g8``)
-
-``mental_model_versions`` is intentionally *not* widened here: it is created in
-``j5e6f7g8h9i0`` but dropped (``DROP TABLE ... CASCADE``) in ``o0j1k2l3m4n5`` and
-never recreated on the upgrade path, so it does not exist at head. Issuing
-``ALTER TABLE mental_model_versions ...`` would raise ``UndefinedTable`` and --
-because migrations run inside the lifespan-startup transaction -- roll the whole
-migration back, bricking the API. (It is unrelated to the live
-``mental_model_history`` table widened by ``c3e5a7b9d1f4``.)
-
-``banks.bank_id`` is ``TEXT`` (unbounded), so a deployment can create a bank
-whose id exceeds 64 chars -- the 78-char hierarchical org-unit shape reported in
-issue #2106 -- and the bank insert succeeds. The next write that propagates that
-id (``create_directive``, ``create_mental_model`` / consolidation, or
-mental-model versioning) then aborts with::
-
-    psycopg2.errors.StringDataRightTruncation: value too long for type
-    character varying(64)
-
-i.e. a 500 on core write endpoints, instead of the startup brick that
-``c3e5a7b9d1f4`` already repaired.
-
-``ALTER COLUMN ... TYPE TEXT`` is a no-op on a column that is already ``TEXT``,
-so every upgrade path converges on ``TEXT``. These tables are per-tenant (they
-live in each tenant schema, not ``public``), so this runs for every migrated
-schema via the search-path-aware prefix -- the same mechanism as
-``c3e5a7b9d1f4``.
-
-PostgreSQL only: these tables are created by PostgreSQL-only migrations
-(``run_for_dialect(pg=...)``); on Oracle they are absent or already
-``VARCHAR2(256)`` (consistent, never truncates), so the Oracle slot is
-intentionally absent -- mirroring ``c3e5a7b9d1f4``.

-"""Move mental-model and observation history into dedicated tables.
-
-Both histories were accumulated in a single JSONB/CLOB ``history`` column
-(``mental_models.history`` and ``memory_units.history``), appended to on every
-update. That design has two problems:
-
-1. **Unbounded growth on observations.** The observation write path appended a
-   snapshot on every update with no cap at all, so a frequently-reinforced
-   observation grew its ``history`` array until it crossed Postgres's hard 256MB
-   jsonb limit (SQLSTATE 54000), after which every further UPDATE failed and the
-   row was stuck.
-2. **Wrong-axis cap on mental models.** The mental-model cap bounded the *number*
-   of entries (50), not their *size* — a single large reflect snapshot could
-   still blow the budget — and rewrote the whole array (plus TOAST) on every
-   refresh, defeating HOT updates.
-
-This migration creates one row per history entry in two dedicated tables, with
-an index that makes "most recent N for this item" cheap, then drops the old
-columns. The cap is now enforced at write time as a bounded DELETE of the
-oldest over-cap rows (see config ``*_HISTORY_MAX_ENTRIES``).

-"""Repair: install maintenance routines on the ``public`` / base-schema run.
-
-The original maintenance-routines migration (``e5f6a7b8c9d0``) only created the
-shared ``public.banks_needing_consolidation()`` and
-``public.schemas_with_expired_rows(...)`` routines when the run had *no*
-``target_schema`` at all. But the single-tenant runtime always migrates an
-explicit schema — which defaults to ``public`` — so on every default
-PostgreSQL deployment the migration was stamped as applied while the functions
-were never created. Background maintenance then logs::
-
-    Retention sweep failed for llm_requests: function public.schemas_with_expired_rows(...) does not exist
-    Consolidation reconcile discovery failed: function public.banks_needing_consolidation() does not exist
-
-See https://github.com/vectorize-io/hindsight/issues/2056.
-
-Because ``e5f6a7b8c9d0`` is already stamped on affected ``0.8.0`` databases,
-editing it would not re-run it there. This forward migration re-installs the
-functions idempotently (``CREATE OR REPLACE``) on the run that targets the
-shared ``public`` schema (base run with no ``target_schema``, or an explicit
-``target_schema=public``), self-healing already-upgraded deployments and
-covering fresh upgrades from earlier versions.
-
-Per-tenant runs against a non-``public`` schema still skip it: re-issuing
-``CREATE OR REPLACE FUNCTION public....`` from each concurrent tenant migration
-aborts with ``tuple concurrently updated`` on the ``pg_proc`` catalog row, and
-the base/public run has already created the functions for every tenant to use.
-Runs that target ``public`` are serialized by the per-schema migration advisory
-lock, so only one wins the create.
-
-PostgreSQL only — the worker poller and these tables are not wired for Oracle,
-so the Oracle slot is intentionally absent (mirrors ``e5f6a7b8c9d0``).

-Revision ID: b5d4e3f2a1c9
-Revises: o1a2b3c4d5e6
-Create Date: 2026-04-24

-The writer path in `entity_resolver.link_units_to_entities_batch` historically
-stamped `entity_cooccurrences.last_cooccurred` with `datetime.now(UTC)` at
-flush time, ignoring the source memory unit's event date. For normal online
-retains that's fine (now ≈ event time), but for any corpus that was
-backfilled in a single session — migrating from another memory system, for
-example — every co-occurrence collapsed to the import moment, which hid the
-underlying knowledge timeline from the dashboard's entity graph recency heat
-and from any downstream consumer of the column.
-
-The writer is fixed in the same change set to propagate the unit's event_date;
-this migration repairs historical rows by reading the true event time off
-`unit_entities × memory_units` (falling back to `created_at` when
-`mentioned_at` / `occurred_start` are NULL, so rows never regress).
-
-Oracle slot is intentionally absent: the Oracle baseline (`o1a2b3c4d5e6`)
-landed days before this fix, so any Oracle deployment runs the corrected
-writer against an effectively empty `entity_cooccurrences` — there is no
-historical residue on Oracle to repair. PG-only matches the asymmetry of
-the data, not negligence.

-vchordrq operator classes are bound 1:1 to operators in PostgreSQL:
-vector_l2_ops only matches ``<->``, while every Hindsight ANN query uses
-``<=>`` (cosine distance). The previous vchord mapping used vector_l2_ops,
-so vchord deployments could never use the index — every ANN query fell
-back to a sequential scan with per-row cosine computation.
-
-This migration finds any vchordrq index built with vector_l2_ops in the
-target schema and re-creates it with vector_cosine_ops, using
-``CREATE INDEX CONCURRENTLY`` so it can run online. It is a no-op when:
-
-* the configured vector extension is not vchord, or
-* no matching indexes exist (already on cosine ops).
-
-Only PostgreSQL is affected; the Oracle 23ai dialect uses its own native
-vector index and does not depend on this mapping.

-"""Repair: widen ``*_history.bank_id`` from VARCHAR(64) to TEXT on PostgreSQL.
-
-The original split-history migration (``a7b8c9d0e1f2``) declared
-``observation_history.bank_id`` and ``mental_model_history.bank_id`` as
-``VARCHAR(64)`` on PostgreSQL. But ``memory_units.bank_id`` — the backfill
-source for observations — is ``TEXT`` (unbounded), as are ``banks``,
-``documents`` and ``entities``. Any deployment whose ``bank_id`` exceeds 64
-characters aborts the backfill ``INSERT`` with::
-
-    psycopg2.errors.StringDataRightTruncation: value too long for type
-    character varying(64)
-
-Because the migration runs in ``lifespan`` startup inside a transaction, the
-whole migration rolls back and the API never comes up — unrecoverable from the
-running container. See https://github.com/vectorize-io/hindsight/issues/2106.
-
-``a7b8c9d0e1f2`` itself has been corrected to create the column as ``TEXT``,
-which unblocks deployments that *failed* (the migration rolled back, so it
-re-runs the fixed DDL). This forward migration covers deployments that already
-*succeeded* with the narrow ``VARCHAR(64)`` column — where editing
-``a7b8c9d0e1f2`` has no effect because it will not re-run — by widening the
-column in place. ``ALTER COLUMN ... TYPE TEXT`` is a no-op on a column that is
-already ``TEXT`` (fresh installs and re-run failures), so every upgrade path
-converges on ``TEXT``.
-
-The history tables are per-tenant (they live in each tenant schema, not
-``public``), so this runs for every migrated schema via the search-path-aware
-prefix — unlike the shared-``public`` routines repaired in ``b2d4f6a8c1e3``.
-
-PostgreSQL only. On Oracle both ``memory_units.bank_id`` and the history
-``bank_id`` columns are already ``VARCHAR2(256)`` (consistent, never
-truncates), so the Oracle slot is intentionally absent.

-"""Backfill search_vector for native-backend observations.
-
-Observations created or updated by the consolidator landed with a NULL
-``search_vector`` under the ``native`` text-search backend: the
-single-row INSERT/UPDATE paths in ``consolidator.py`` never populated the
-tsvector (only the batch raw-fact path in ``ops_postgresql.insert_facts_batch``
-did). Those observations were therefore invisible to the BM25 retrieval arm
-until they were re-written by a later consolidation pass. The writer is fixed
-in the same change set (all four consolidator sites now call
-``to_tsvector($lang, COALESCE(text, ''))``); this migration repairs the
-historical residue so existing observations become BM25-searchable without a
-re-ingest.
-
-Scope mirrors the writer fix exactly:
-  * Only the ``native`` backend is touched. The gate is the column *type*:
-    under ``native`` ``search_vector`` is a regular (non-generated) tsvector
-    column; under ``vchord`` it is a ``bm25vector`` and under
-    ``pg_textsearch`` / ``pgroonga`` / ``pg_search`` it is a dummy ``text``
-    column. ``_is_regular_tsvector`` is true only for ``native``, so every
-    other backend is a no-op.
-  * The tsvector is built from the observation's own ``text`` only — matching
-    the consolidator INSERT/UPDATE paths (entity / source / temporal signals
-    are intentionally excluded; the other retrieval arms cover those).
-  * Only ``fact_type = 'observation'`` rows with a NULL ``search_vector`` are
-    rewritten. Raw facts already carry a populated tsvector, and the
-    ``IS NULL`` predicate makes the migration idempotent and re-runnable.
-
-The configured ``HINDSIGHT_API_TEXT_SEARCH_EXTENSION_NATIVE_LANGUAGE`` is used
-so backfilled rows are lexically identical to newly-created observations. The
-value is validated as a PG identifier (mirroring
-``HindsightConfig.validate``) before being embedded as a SQL literal.
-
-This is a single UPDATE per schema: it locks the targeted observation rows for
-its duration. It is one-time and only touches unpopulated rows, so subsequent
-online writes (which now carry the tsvector via the writer fix) are unaffected.
-
-Oracle slot is intentionally absent: the consolidator INSERT/UPDATE paths that
-this repairs are PostgreSQL-specific (``ops_postgresql``), and the native
-tsvector ``search_vector`` column only exists on PostgreSQL. There is no Oracle
-residue to repair.

-"""Make maintenance routines resilient to schemas that vanish mid-scan.
-
-``public.banks_needing_consolidation()`` and
-``public.schemas_with_expired_rows(...)`` snapshot the set of schemas owning a
-target table from ``pg_class`` and then run a dynamic query against each schema
-in turn. That is a time-of-check/time-of-use race: a schema (or its tables) can
-be dropped — a tenant being deleted, or a tenant migration that recreates
-tables — between the snapshot and the per-schema query, which then aborts the
-whole routine with::
-
-    relation "<schema>.memory_units" does not exist
-    relation "<schema>.audit_log" does not exist
-
-In the test suite this surfaces as cross-worker contamination: the multi-tenant
-maintenance test creates and drops ~100 ``mt<hash>_NNN`` schemas while
-``test_maintenance_routines`` (on another xdist worker, same DB) calls the
-routines. In production the background maintenance loop hits the same race when
-a tenant is removed or mid-migration.
-
-Wrap each per-schema query in its own ``BEGIN ... EXCEPTION`` block so a schema
-that disappears (``undefined_table`` / ``invalid_schema_name`` /
-``undefined_column``) is skipped instead of aborting the scan. The routines stay
-``CREATE OR REPLACE`` and PostgreSQL-only, and are (re)installed only on the run
-that targets the shared ``public`` schema — same gating as the original
-install (``e5f6a7b8c9d0``) and its repair (``b2d4f6a8c1e3``).

-"""Add invalidated_memory_units table for curation (edit/invalidate).
-
-Curation keeps the recall hot-path (``memory_units``) clean by *moving*
-invalidated facts into a sibling archive table rather than flagging them in
-place. If a row is in ``memory_units`` it is live; if it is in
-``invalidated_memory_units`` it has been retired. Recall/consolidation/graph
-queries never need a state predicate — the rows simply aren't there.
-
-The archive mirrors ``memory_units`` column-for-column — except ``embedding``,
-which it never keeps: the archive is cold storage, never a recall surface, and
-revert recomputes the embedding from the unit's text/dates/entities. Keeping no
-archive vector also means a later embedding-model switch (which re-dimensions
-``memory_units``) can't trip a dimension mismatch on the move (#2209). Plus:
-- ``invalidation_reason``  optional free text recorded on invalidate
-- ``invalidated_at``       when it was retired
-- ``entity_ids``           snapshot of the unit's entity associations, so revert
-                           can restore them (``unit_entities`` is cascade-deleted
-                           when the live row is removed)
-
-This migration also adds ``edited_at`` to ``memory_units``: set whenever a user
-edits a memory's fields (text, context, dates, fact_type, entities) via curation.
-NULL means never manually modified; a non-NULL value answers "has the user ever
-changed this?" with the time of the last edit (distinct from ``updated_at``,
-which background operations also bump). It is added to ``memory_units`` *before*
-the archive is cloned below, so the archive inherits the column and the marker
-travels with a fact when it is invalidated.

-"""Drop the embedding column from the curation archive (invalidated_memory_units).

-The archive is cold storage, never a recall surface, so it has no business
-keeping an embedding. Earlier curation code copied the live row's embedding into
-``invalidated_memory_units`` on invalidate; the engine now leaves it out on
-invalidate and recomputes it on revert, so the column is dead weight.
-
-Dropping it makes "the archive holds no embedding" a schema-enforced invariant
-rather than a convention the move queries have to honour, and removes a latent
-failure mode (#2209): after an embedding-model switch the live tables are
-re-dimensioned but the archive was not, so a stale old-dimension embedding in
-the archive tripped a vector-dimension mismatch on the INSERT … SELECT
-round-trip. With no column at all, there is nothing to mismatch.
-
-The creation sites no longer add the column (the PG ``LIKE`` clone in
-c9a1b2d3e4f5 drops it; the Oracle baseline omits it), so on a fresh database
-this migration is a no-op (DROP ... IF EXISTS / Oracle ORA-00904 swallow). It
-does the real work on databases created before the column was removed there.
-
-DROP COLUMN is a metadata-only operation on both PostgreSQL and Oracle 23ai (no
-table rewrite), so it is cheap even across many tenant schemas. The downgrade
-re-adds an unconstrained vector column (any dimension) — empty, since the
-embeddings are intentionally discarded.

   clause, because the idx_memory_units_bank_id B-tree index always wins at planning time.
 - Per-(bank, fact_type) partial indexes have both predicates matching → planner selects them.
 - The global vector index competes for larger partitions (world, observation) and must be dropped.
-- AlloyDB ScaNN uses global vector indexes with filtered vector search instead
-  because empty or tiny per-bank indexes cannot be built safely.
