 # OpenGeoMetadata API
 
-This repository now runs entirely from [backend](backend/), which mirrors the current BTAA Geospatial API backend while being themed and operated for the OpenGeoMetadata community.
-
-The old root-level API implementation has been retired into [legacy/root_api](legacy/root_api/). The repo root is now just project scaffolding for Docker, Kamal, docs, and convenience commands; the application code lives in `backend/`.
-
-## Local Setup
+OpenGeoMetadata API is a deployable search, harvest, and delivery service for
+public [OpenGeoMetadata](https://opengeometadata.org/) Aardvark records. It is
+being prepared as the reference API node for the proposed
+[OpenGeoMetadata API Mirror Network](https://github.com/OpenGeoMetadata/ogm-mirror-network).
+
+> [!IMPORTANT]
+> The mirror-network proposal is a **Draft for Community Discussion**
+> (`OGM-DISCUSSION-2026-01`), not an approved OGM roadmap, production
+> commitment, or technical standard. This repository implements capabilities a
+> mirror node needs; it does not claim that the proposed network already exists.
+
+## Role in the mirror network
+
+The proposal separates the public service from any one institution:
+
+1. Public Aardvark files in OpenGeoMetadata GitHub repositories remain the
+   canonical metadata source.
+2. Each mirror independently harvests that corpus into local PostgreSQL and
+   Elasticsearch services and keeps its own Redis and generated caches.
+3. A protected global endpoint would route public read traffic only to mirrors
+   that are compatible, healthy, sufficiently current, and within capacity.
+4. Institutional OGM Discovery sites would use the stable network endpoint
+   rather than bind themselves to one campus origin.
+5. The OGM service operator would deploy the same pinned application release
+   to each mirror with Kamal, using staged upgrades and rollback.
+
+This repository supplies the API/node software in that model. The
+[technical implementation guide](https://github.com/OpenGeoMetadata/ogm-mirror-network/blob/main/proposal/opengeometadata-api-mirror-network-technical-implementation.md)
+is the canonical source for the proposed network architecture and pilot
+acceptance criteria.
+
+## Current implementation status
+
+| Capability | Status |
+| --- | --- |
+| Discover OpenGeoMetadata repositories and harvest `metadata-aardvark/` | Implemented |
+| Nightly reconciliation with webhook-triggered acceleration | Implemented for the current production node |
+| PostgreSQL record/provenance state and Elasticsearch discovery index | Implemented |
+| Redis hot caches plus durable generated representations and visual assets | Implemented |
+| Public search, resource, OGC, MCP, viewer, thumbnail, and static-map APIs | Implemented |
+| Single-host Kamal topology with web, worker, cron, PostgreSQL, Elasticsearch, and Redis | Implemented |
+| OGM repository monitoring dashboard | Implemented |
+| Shared global edge, origin drain/rejoin, and weighted multi-mirror routing | Proposed pilot work |
+| Network readiness contract and deterministic `corpus_generation` | Proposed pilot work |
+| Shared webhook fan-out and fleet-wide release orchestration | Proposed pilot work |
+| Demonstrated multi-node failover and rebuild acceptance tests | Proposed pilot work |
+
+Administrative, webhook, harvest, reindex, and deployment operations are a
+restricted control plane. A future shared endpoint is intended only for safe
+public `GET` and `HEAD` routes.
+
+## Repository layout
+
+- `backend/` — FastAPI application, workers, migrations, scripts, and tests
+- `config/` — Kamal deployment, cron, database initialization, and upstream provenance
+- `docs/` — operator, development, cache, deployment, and migration documentation
+- `scripts/` — repository-level upstream and registry helpers
+- `legacy/root_api/` — retired pre-backend implementation; not the runtime application
+
+The backend began from the `geobtaa/api` backend subtree and now carries an
+OpenGeoMetadata-owned harvesting, branding, deployment, and cache overlay. It
+is not a Git fork with mergeable history. See
+[BTAA backend reconciliation](docs/upstream_reconciliation.md) for the pinned
+source baseline, selective-port decisions, and accepted upstream fixes.

@@ -12,159 +73,141 @@ Copy the environment template:
 cp .env.example .env
 ```
 
-The checked-in `.env.example` is host-friendly for backend-local commands. Docker services override the container-only hostnames internally, so the same `.env` also works with `docker compose`.
-
-For local Docker development, Elasticsearch defaults `ELASTICSEARCH_DISK_THRESHOLD_ENABLED=false` so Docker Desktop disk-watermark quirks do not leave the single-node index unassigned. If you want stricter production-like allocation checks, set it back to `true` in `.env`.
-
-If you want to run the backend directly on your host machine, install dependencies with `uv`:
-
-```bash
-uv venv
-source .venv/bin/activate
-cd backend
-uv pip install -e ".[dev]"
-```
-
-## Run With Docker
+Do not place production credentials in the repository. `.env` and `.kamal/`
+are ignored local files; shared deployments must resolve secrets from an
+approved environment or secret manager.
 
-Start the API plus its backing services:
+Start the complete local stack:
 
 ```bash
 docker compose up -d --build
-```
-
-Then initialize the app. The most reliable path is to run backend scripts inside the API container:
-
-```bash
 docker compose exec api bash -lc "cd /app/backend && python scripts/run_migrations.py"
 docker compose exec api bash -lc "cd /app/backend && python scripts/run_index.py"
 ```
 
-`scripts/run_gazetteers.py` is optional for OGM-focused local work and can usually be skipped unless you specifically need the gazetteer-backed enrichment features.

+## Harvesting and indexing
 
-## Common Commands
+The current node supports:
 
-From the repo root:
+- repository discovery with `backend/scripts/populate_ogm_repos.py`;
+- scheduled reconciliation with `backend/scripts/trigger_ogm_nightly_sync.py`;
+- signed webhook ingestion at `POST /api/v1/admin/ogm/webhook`; and
+- explicit index construction with `backend/scripts/run_index.py`.
 
-```bash
-cd backend && python scripts/trigger_ogm_nightly_sync.py --dry-run
-cd backend && python scripts/run_migrations.py
-cd backend && python scripts/run_index.py
-cd backend && python scripts/run_gazetteers.py
-cd backend && python scripts/prime_generated_caches.py --limit 100
-```
+Set `GITHUB_TOKEN` in the local environment when running GitHub discovery at a
+rate that exceeds anonymous API limits. Set `OGM_WEBHOOK_SECRET` only through
+the deployment secret source.
 
-Or use Make targets:
+Common commands from the repository root:
 
 ```bash
 make migrate
 make reindex
-make gazetteers
 make ogm-nightly
 make cache-prime ARGS="--limit 100"
-make cache-prime-background ARGS="--limit 1000"
 make test
+make lint-check
 ```
 
-If you prefer not to install Python dependencies locally, the same commands can be run in Docker:
-
-```bash
-docker compose exec api bash -lc "cd /app/backend && python scripts/run_migrations.py"
-docker compose exec api bash -lc "cd /app/backend && python scripts/run_index.py"
-docker compose exec api bash -lc "cd /app/backend && python scripts/prime_generated_caches.py --limit 100"
-docker compose exec api bash -lc "cd /app/backend && python scripts/trigger_ogm_nightly_sync.py --dry-run"
-```
+Pull requests and pushes to `develop` run the complete backend suite in GitHub
+Actions against isolated ParadeDB, Elasticsearch, and Redis services. The CI
+job also produces a coverage artifact and enforces a 50% application coverage
+floor.
 
-## OGM Harvesting
+The nightly reconciliation path is the correctness mechanism. Webhooks reduce
+freshness latency but must not be the only way a mirror discovers changes.
 
-The backend includes:
+## Generated caches
 
-- GitHub-org discovery via `backend/scripts/populate_ogm_repos.py`
-- nightly repo refresh + harvest enqueue via `backend/scripts/trigger_ogm_nightly_sync.py`
-- webhook-triggered harvesting via `POST /api/v1/admin/ogm/webhook`
+Resource representations, thumbnails, and static maps are generated runtime
+data. They are stored in Redis and durable database-backed caches and are not
+committed as source files.
 
-Set `GITHUB_TOKEN` in `.env` before running the OGM sync scripts if you want to avoid low unauthenticated GitHub API rate limits.
-
-For near-real-time harvesting, configure an OpenGeoMetadata organization webhook:
-
-- Payload URL: `https://ogm.geo4lib.app/api/v1/admin/ogm/webhook`
-- Content type: `application/json`
-- Secret: production `OGM_WEBHOOK_SECRET`
-- Events: `repository`, `public`, and `push`
-
-The webhook discovers newly created/publicized/transferred/unarchived OGM repos, enables repos
-with a top-level `metadata-aardvark/` directory, and queues harvests when pushes touch
-`metadata-aardvark/`. The nightly job remains the reconciliation path in case a delivery is missed.
-
-For a first local bootstrap with real OGM data:
+After migrations and indexing, warm a bounded set:
 
 ```bash
-docker compose exec api bash -lc "cd /app/backend && python scripts/populate_ogm_repos.py"
-docker compose exec api bash -lc "cd /app/backend && python - <<'PY'\nfrom app.tasks.ogm_harvest import ogm_harvest_all\nprint(ogm_harvest_all.delay(trigger='nightly').id)\nPY"
-docker compose exec api bash -lc "cd /app/backend && python scripts/run_index.py"
+make cache-prime ARGS="--limit 1000"
 ```
 
-The harvest populates Postgres first. Re-run `python scripts/run_index.py` from `backend/` after the harvest queue completes so Elasticsearch reflects the imported OGM records.
+See [cache priming](docs/cache_priming.md) for production and background
+workflows. Full-corpus runs deliberately avoid loading every image body into
+Redis.
 
-Production also has a dedicated monitor page at `/api/v1/ogm/repos/dashboard` and a nightly
-GitHub Actions workflow for OGM repo discovery + harvest orchestration.
+## Releases and upstream provenance
 
-See [docs/backend_upstream_sync.md](docs/backend_upstream_sync.md) for the upstream-sync and repo-watching strategy.
+OGM product versions and BTAA backend provenance are separate:
 
-## Generated Cache Priming
+- the product version describes this repository's API contract and release;
+- `config/geobtaa-backend-source.env` records the last complete BTAA subtree
+  import; and
+- `docs/upstream_reconciliation.md` records selective ports made after that
+  import.
 
-After migrations and indexing, prebuild generated artifacts with:
+Do not merge `geobtaa/api` into this repository. Preview a complete backend
+import only when a deliberate rebase of the downstream product is intended:
 
 ```bash
-make cache-prime ARGS="--limit 1000"
+./scripts/sync_backend_from_data_api.sh
 ```
 
-For a production background run after deploy:
+The helper protects the paths in `config/ogm-owned-paths.txt`. An applied
+import still requires diff review, the complete test suite, and a new
+reconciliation record.
 
-```bash

+## Deployment and repository transfer
 
-The combined primer warms durable generated resource representations, thumbnail
-assets, and static-map/basemap assets. Full-corpus runs avoid hydrating every
-image body into Redis by default; add `--hydrate-assets` only for bounded hotsets
-or hosts sized for that memory profile.
+The current production node uses Kamal. Its stable operational identity is the
+`ogm-api` service, existing hostname, role topology, accessory names, and host
+volume paths—not the GitHub repository URL.
 
-See [docs/cache_priming.md](docs/cache_priming.md) for details.
+Repository transfer and container-registry migration are intentionally
+separate changes. Preserve the running image path during the GitHub transfer,
+then prove an organization-owned image with dual publication and rollback
+before changing `config/deploy.yml`.
 
-## Upstream Backend Sync
+Read these before an operational change:
 
-This repo is maintained as the OpenGeoMetadata API product with `backend/`
-imported from `geobtaa/api`.
+- [Deployment guide](docs/deployment.md)
+- [Repository transfer runbook](docs/repository_transfer.md)
+- [Repository transfer rehearsal](docs/repository_transfer_rehearsal.md)
+- [Pre-transfer branch inventory](docs/repository_branch_inventory.md)
+- [BTAA backend reconciliation](docs/upstream_reconciliation.md)
+- [Backend sync design](docs/backend_upstream_sync.md)
 
-Preview an upstream backend import:
+Never change the Kamal service name, persistent volume paths, repository owner,
+and image namespace in one deployment.
 
-```bash
-./scripts/sync_backend_from_data_api.sh
-```
+## Project status and participation
 
-Apply after review:
+This codebase is being prepared for community ownership under the
+OpenGeoMetadata organization. Mirror-network governance, sponsorship, service
+objectives, edge ownership, and pilot authorization remain community
+decisions. Discussion of the proposal belongs in the
+[ogm-mirror-network issue tracker](https://github.com/OpenGeoMetadata/ogm-mirror-network/issues).
 
-```bash
-./scripts/sync_backend_from_data_api.sh --apply
-```
+Code contributions should preserve the public API contract, keep derived state
+rebuildable from canonical GitHub metadata, include focused tests, and document
+any change to deployment or upstream provenance.

+It exists so the history rewrite and organization transfer use an intentional
+ref set. Branch deletion is not performed by repository preparation scripts.

+At audit time the repository had 18 live branches, no tags, and no open pull
+requests. All ten historical pull requests were closed and merged.

+## Unmerged historical branches
+
+These branches have no pull requests and have been inactive since 2025. Their
+patches are not byte-for-byte present in `develop`, so deletion needs an owner
+decision even though their intended capabilities have been superseded.
+
+| Branch | Behind/ahead | Unique commits | Assessment | Recommended disposition |
+| --- | ---: | --- | --- | --- |
+| `feature/duckdb-shapefiles` | 97 / 1 | `f3870d0` | Early shapefile endpoint plus a committed 3.4 MB DuckDB file and large lockfile change. Current `develop` has a maintained shapefile service and endpoint test coverage. | Delete after owner confirmation |
+| `feature/geosearch` | 97 / 2 | `2277261`, `efce8eb` | Initial bbox search. Current `develop` has normalized bbox filters, scoring, containment behavior, and extensive tests. The same branch also remains in the BTAA upstream remote. | Delete after owner confirmation |
+| `feature/test-suite` | 174 / 1 | `e2f8305` | Initial test harness with a committed SQLite test database. Current `develop` has 158 backend test modules and a passing 1,831-test suite. | Delete after owner confirmation |
+
+If any historical branch must be retained for archaeology, preserve it outside
+the transferred repository with an access-controlled `git bundle` and record
+its full commit SHA in the private migration record. Do not create archive tags
+inside this repository: tags keep the same objects reachable and defeat ref
+cleanup.
+
+## Cutover procedure
+
+1. Freeze pushes and repeat the live branch inventory.
+2. Confirm that no pull request is open and no collaborator has unpublished
+   work based on a branch slated for deletion.
+3. Obtain explicit owner approval for the three unmerged branches.
+4. Delete approved remote branches while the repository is still under the
+   personal owner.
+5. Fetch with pruning into the cutover workstation and verify that local
+   `origin/*` refs exactly match GitHub.
+6. Populate the fresh rewrite mirror only from the approved live heads and
+   tags. Never include `upstream/*` refs or locally fetched BTAA tags.
+7. Record the final ref names and pre-rewrite SHAs in the private change record.
+
+The tested rewrite can preserve all 18 branches, so branch pruning is a
+governance and cleanliness decision rather than a technical prerequisite. The
+recommended community-facing end state is a single `develop` branch unless an
+OpenGeoMetadata maintainer asks to retain another ref.

+# Repository transfer and production continuity runbook
+
+This runbook moves `ewlarson/ogm-api` to `OpenGeoMetadata/ogm-api` without
+coupling GitHub ownership to a production deployment. The repository transfer
+is a control-plane change. It must not restart containers, change the Kamal
+service identity, move persistent data, or change the image pulled by
+production.
+
+GitHub normally preserves issues, pull requests, releases, webhooks, deploy
+keys, secrets, and redirects when a repository is transferred. Organization
+policy and package permissions still require explicit verification. Review
+GitHub's current [repository transfer documentation](https://docs.github.com/en/repositories/creating-and-managing-repositories/transferring-a-repository)
+immediately before the change.
+
+See `repository_transfer_rehearsal.md` for the dated, non-secret evidence from
+the isolated history-rewrite and live preflight rehearsal. That evidence must
+be refreshed during the actual change window.
+
+See `repository_branch_inventory.md` for the disposition of all live personal
+repository branches. Do not copy every fetched ref into the cutover mirror by
+default; only GitHub-owned refs approved in that ledger belong in the transfer.
+
+## Stop conditions
+
+Do not transfer the repository until all of these are true:
+
+- a secret scan of every repository-owned branch and tag is clean, and any
+  credential the scan identifies has been rotated at its authority;
+- a coordinated history rewrite has removed generated `backend/static/maps/`
+  assets from every branch and tag (the rewrite also strips Kamal secret paths
+  defensively);
+- the rewritten repository passes `make transfer-readiness-full`;
+- the OpenGeoMetadata owners have approved the repository name, visibility,
+  teams, branch policy, Actions policy, and secret owners;
+- every live branch has an approved keep/delete disposition and no open pull
+  request or collaborator work depends on a branch slated for deletion;
+- the currently deployed image reference and digest, Kamal version, and
+  rollback version have been recorded; and
+- a production database backup and a host-volume snapshot or equivalent
+  recovery point have been verified.
+
+The preparation audit found `.kamal/secrets` in commits reachable only from the
+separate `geobtaa/api` upstream remote, not in branches owned by
+`ewlarson/ogm-api`. It found no shared assignments between that upstream file
+and the current ignored local operator file. Do not import upstream refs or
+tags into the transferred repository. If a subsequent scanner finds a secret
+in an OGM-owned ref, treat it as compromised: removing Git history does not
+revoke a credential and is not a substitute for rotation.
+
+## Production invariants
+
+The following values are intentionally frozen through the repository transfer:
+
+| Invariant | Current value |
+| --- | --- |
+| Kamal service | `ogm-api` |
+| Production host and proxy hostname | `ogm.geo4lib.app` |
+| Roles | `web`, `worker`, `cron` |
+| Container image | `ewlarson/opengeometadata-api` |
+| Registry and login owner | `ghcr.io`, `ewlarson` |
+| Elasticsearch index | `opengeometadata_api` |
+| PostgreSQL database | `btaa_ogm_api` |
+| Elasticsearch volume | `/var/lib/opengeometadata-api/elasticsearch` |
+| PostgreSQL volume | `/var/lib/opengeometadata-api/postgres` |
+| Redis volume | `/var/lib/opengeometadata-api/redis` |
+
+The legacy PostgreSQL database name is persistent identity, not public project
+branding. Rename it only in a separate, backed-up database migration.
+
+Run the local invariant checks before and after every preparation commit:
+
+```bash
+make transfer-readiness
+```
+
+## Phase 1: verify and externalize secrets
+
+1. Scan every OGM-owned branch and tag without copying suspected values into an
+   issue, chat, log, or pull request.
+2. If the scan identifies a credential, rotate it at its authority. Relevant
+   classes include registry/GitHub tokens, database/admin credentials, webhook
+   signing secrets, SSH material, and third-party API credentials.
+3. Replace any rotated deployment value through the approved secret source,
+   verify the running application, and only then revoke the old value.
+4. Confirm `.kamal/` remains ignored and that no workflow, fixture, log, or
+   documentation contains a copied value.
+5. Record the scan result and, when applicable, who rotated each credential,
+   its authority, and completion time in the private operational system—not in
+   this repository.
+
+Do not edit the operator's ignored local `.kamal/secrets` file as part of a
+repository cleanup commit; doing so can silently break the next deployment.
+
+## Phase 2: rewrite contaminated and generated history
+
+The current repository-owned branch history contains more than a thousand
+generated static-map paths. Schedule a push freeze and announce that every
+existing clone will need to be re-cloned. Record the last pre-rewrite commit in
+the private change record; do not create a public pre-rewrite tag, because that
+would keep the removed objects reachable. Perform the rewrite in a fresh
+temporary mirror of `origin`, never in an operator's deployment checkout:
+
+```bash
+git clone --mirror git@github.com:ewlarson/ogm-api.git ogm-api-sanitized.git
+cd ogm-api-sanitized.git
+git filter-repo --force \
+  --path .kamal/secrets \
+  --path .kamal/registry-password \
+  --path backend/static/maps \
+  --invert-paths
+```
+
+Inspect every rewritten ref, run a secret scanner approved by the
+OpenGeoMetadata organization, and run the equivalent of:
+
+```bash
+git rev-list --objects --all | grep -E '(^|/)(\.kamal/(secrets|registry-password)|backend/static/maps/)'
+```
+
+The command must return no paths. Only after verification should the release
+operator force-push all rewritten branches and tags. Remove cached forks or
+temporary mirrors that could reintroduce the old objects, preserve the private
+audit record, and require collaborators to re-clone.
+
+## Phase 3: record the running deployment
+
+From the operator workstation, record these outputs in the private change
+record:
+
+```bash
+git rev-parse HEAD
+kamal version
+kamal details
+kamal app images
+```
+
+Also record the active container image including its immutable digest, the
+previous known-good image, accessory health, free disk space, last successful
+nightly reconciliation, database backup identifier, and a small production
+smoke-test result. Do not run `kamal deploy` during the GitHub transfer.
+
+The transfer operator must separately confirm that the personal GHCR image is
+still readable by the production host. GitHub repository transfer does not
+make a personal container package organization-owned. Package linkage and
+access are managed separately; review GitHub's current
+[package/repository connection documentation](https://docs.github.com/en/packages/learn-github-packages/connecting-a-repository-to-a-package).
+
+## Phase 4: transfer the repository
+
+1. Freeze pushes and scheduled/manual deployment activity.
+2. Run `make transfer-readiness-full` against the exact commit being moved.
+3. In GitHub, transfer the repository to `OpenGeoMetadata` using the unchanged
+   repository name `ogm-api`.
+4. Do not create a replacement `ewlarson/ogm-api`; that would interfere with
+   GitHub's redirect from the old URL.
+5. Update the local Git remote after the transfer:
+
+   ```bash
+   git remote set-url origin git@github.com:OpenGeoMetadata/ogm-api.git
+   git remote -v
+   ```
+
+6. Run `./scripts/verify_transfer_readiness.sh --post-transfer`.
+
+No production containers should change during these steps.
+
+## Phase 5: verify GitHub controls and automation
+
+Immediately verify:
+
+- repository visibility, default branch (`develop`), tags, releases, issues,
+  pull requests, discussions, and redirect behavior;
+- OpenGeoMetadata owner/admin access and least-privilege team access;
+- branch protection or rulesets, required checks, Actions permissions, and
+  environment approval rules;
+- webhooks, deploy keys, GitHub Apps, security settings, vulnerability alerts,
+  and code-scanning configuration;
+- Actions secrets `OGM_KAMAL_SSH_PRIVATE_KEY`, `OGM_KAMAL_SSH_HOST`,
+  `OGM_KAMAL_SSH_PORT`, and `OGM_KAMAL_SSH_USER`; and
+- that the nightly workflow can locate a running container labeled
+  `service=ogm-api` and complete one manually dispatched reconciliation.
+
+Verify the public API, OpenAPI document, a representative search, a resource
+response, sitemap/robots behavior, and the harvest dashboard. Then unfreeze
+normal repository activity. A successful repository transfer does not require
+or authorize a production deployment.
+
+## Phase 6: migrate the image namespace later
+
+Move from the personal package to an organization-owned GHCR package only in a
+separate release:
+
+1. create `ghcr.io/opengeometadata/opengeometadata-api` with explicit package
+   access for the repository and deployment principals;
+2. publish the same immutable release to both personal and organization image
+   names;
+3. verify matching image digests and pull the organization image from the
+   production host before editing Kamal configuration;
+4. change only the Kamal image/registry settings, keeping the service, host,
+   roles, index, database, accessory names, and volume paths fixed;
+5. deploy during a separate window, verify health and data continuity, and
+   keep the personal image available for rollback; and
+6. retire the personal package only after a complete rollback window and an
+   independent cold-start/pull test.
+
+## Rollback
+
+If GitHub ownership or policy is wrong, freeze writes and transfer the
+repository back while the original owner and name are still available. The
+running application is unaffected because its image and host were not changed.
+
+If the nightly workflow fails, disable its schedule or leave it frozen, run the
+existing production reconciliation through the recorded operator path, and fix
+organization secrets/permissions before re-enabling it.
+
+If the later image migration fails, restore
+`ewlarson/opengeometadata-api` and the recorded immutable tag/digest, then use
+the normal Kamal rollback procedure. Never remove or recreate PostgreSQL,
+Elasticsearch, or Redis accessories as part of an image rollback.
+
+## Completion evidence
+
+The migration is complete only when the organization repository is the
+documented canonical source, the old URL redirects, all organization controls
+and scheduled workflows are verified, the full-history and secret scans are
+clean (with any actual exposure recorded as rotated), and production continues
+to serve the same data from the same persistent volumes. Organization-owned
+image publication may remain a documented follow-up if the personal image is
+still deliberately pinned and supported.

+# Repository transfer rehearsal evidence
+
+This file records non-secret evidence gathered on 2026-08-19 while preparing
+`ewlarson/ogm-api` for transfer to `OpenGeoMetadata/ogm-api`. It is a snapshot,
+not authorization to transfer. Repeat every live check during the scheduled
+change window and store sensitive operational evidence in the private change
+record described by `repository_transfer.md`.
+
+## Requirement evidence
+
+| Requirement | Evidence | Result |
+| --- | --- | --- |
+| Source repository identity | GitHub reported public, active `ewlarson/ogm-api`, default branch `develop` | Pass |
+| Destination authority | GitHub reported active `admin` membership in `OpenGeoMetadata` | Pass |
+| Destination name | Authenticated request for `OpenGeoMetadata/ogm-api` returned HTTP 404 | Available at check time |
+| Rehearsal source fidelity | All 18 locally fetched `origin/*` branch names and tips matched the live GitHub branch list | Pass |
+| Historical secret paths | Repository-owned history contained zero `.kamal/secrets` or `.kamal/registry-password` paths | Pass |
+| Generated history | Repository-owned history contained 2,108 `backend/static/maps/` paths | Rewrite required |
+| Current worktree | Generated maps are deleted from the index and `backend/static/maps/` is ignored | Pass |
+| Actions secrets | Four expected nightly SSH secret names exist; values were not read | Pass |
+| Other GitHub attachments | Zero webhooks, deploy keys, rulesets, environments, and Actions variables | Pass |
+| Branch disposition | 14 non-default branches are fully merged; three inactive 2025 branches contain superseded unique patches; no pull request is open | Owner decision required for three branches |
+| Source Actions policy | Actions enabled; repository default was write, while each prepared workflow now declares `contents: read` | Pass after prepared changes are published |
+| Destination Actions policy | Token could not read organization policy because it lacks `admin:org` | Manual preflight required |
+| Personal GHCR package metadata | Token could not read package metadata because it lacks `read:packages` | Manual preflight required |
+| Production registry access | Production host successfully inspected the deployed personal GHCR manifest using its existing credentials | Pass |
+| Production topology | Kamal 2.7.0 reported healthy proxy, `web`, `worker`, `cron`, PostgreSQL, Elasticsearch, and Redis containers | Pass |
+| Production API | API root returned version `0.7.0`; representative search returned results | Pass |
+
+## Isolated rewrite rehearsal
+
+The rehearsal populated a new bare repository only from the locally fetched
+`refs/remotes/origin/*` branches after those refs were compared to live GitHub.
+BTAA remote refs and locally fetched BTAA tags were excluded. The temporary
+mirror was rewritten with:
+
+```bash
+git filter-repo --force \
+  --path .kamal/secrets \
+  --path .kamal/registry-password \
+  --path backend/static/maps \
+  --invert-paths
+```
+
+Results:
+
+- all 18 branch names remained present;
+- all 232 source commits received a mapping and none were dropped;
+- sensitive-path count remained zero;
+- generated-map path count fell from 2,108 to zero;
+- `git fsck --full --strict` completed successfully;
+- packed object storage fell from approximately 329 MiB to 122 MiB; and
+- the rewritten `develop` tree retained the `ogm-api` service, personal image
+  path, production hostname, and all three persistent host directory mappings.
+
+The rehearsal mirror was local and disposable. Nothing was force-pushed, no
+repository was transferred, no image was published, and no production state
+was changed.
+
+The sanitized mirror was then cloned into a disposable candidate checkout.
+Every modified, deleted, and untracked path from the prepared shared worktree
+was overlaid onto that checkout. A path-by-path comparison covered 799 source
+paths with zero mismatches. After a temporary candidate-only commit:
+
+- `./scripts/verify_transfer_readiness.sh --full-history` passed every check;
+- `git fsck --full --strict` passed; and
+- the complete backend suite passed with 1,831 tests passed, 99 skipped, and
+  one expected-pass after the existing ignored local test configuration was
+  linked into the disposable checkout; and
+- the candidate worktree was clean.
+
+The temporary rehearsal commit was not created in the shared checkout and was
+not pushed anywhere.
+
+## Change-window evidence still required
+
+Before the actual transfer:
+
+1. commit and review the prepared worktree;
+2. approve `repository_branch_inventory.md`, prune approved branches, freeze
+   pushes, and repeat the live branch-tip comparison;
+3. verify the OpenGeoMetadata Actions policy with an organization-authorized
+   token or in the organization settings UI;
+4. verify personal GHCR package ownership/access with `read:packages`, while
+   keeping production pinned to the personal image path;
+5. create and verify the database backup and host snapshot identified in the
+   private change record;
+6. rewrite a fresh mirror of the frozen GitHub repository and require
+   `make transfer-readiness-full` to pass in a checkout of the result; and
+7. follow the transfer and rollback sequence in `repository_transfer.md`.

+# BTAA backend reconciliation
+
+This repository does not share Git ancestry with `geobtaa/api`. The local
+`develop` branch and `upstream/develop` have no merge base, so Git ahead/behind
+counts are not an integration plan. The supported unit of comparison is the
+BTAA `backend/` subtree recorded in `config/geobtaa-backend-source.env`.
+
+## Baseline and target
+
+| Item | Value |
+| --- | --- |
+| Last imported BTAA commit | `0c9d80b3b36e833fce0a17551da893bf0aa68928` |
+| BTAA tag containing that commit | `v0.7.16` |
+| Recorded backend split | `1cf222b377be4ba1d8468fa864724542e866eb3e` |
+| Review ceiling | BTAA `0.8.11` (`4254aa3`) |
+| OGM product version | Independent; currently `0.7.0` |
+
+The review ceiling is not a promise that this product becomes BTAA `0.8.11`.
+OGM releases and BTAA source provenance are separate concepts.
+
+## Reconciliation policy
+
+1. Review only non-merge commits that affect `backend/` between the recorded
+   baseline and the selected review ceiling.
+2. Classify each change as `ported`, `port selectively`, `dependency review`,
+   `defer`, or `not applicable`.
+3. Port shared behavior with its tests and record the upstream SHA. Do not
+   cherry-pick whole commits across the unrelated histories.
+4. Never overwrite the downstream paths listed in
+   `config/ogm-owned-paths.txt` without an explicit OGM design decision.
+5. Run focused tests for every port, followed by the complete backend suite
+   before release.
+6. Update `config/geobtaa-backend-source.env` only for a complete applied
+   subtree import. Selective ports remain documented here instead.
+
+## Baseline CI coverage
+
+The recorded `v0.7.16` backend baseline postdates BTAA commit `44411cf`, which
+introduced the repository-level CI workflow. The backend subtree import could
+not carry that top-level workflow, so this repository now ports its compatible
+backend job separately in `.github/workflows/ci.yml`.
+
+The port runs the complete Python suite with ParadeDB, Elasticsearch, Redis,
+parallel workers, a wall-clock watchdog, and a 50% coverage floor. BTAA's
+frontend, CLI, QGIS plugin, and MkDocs jobs are intentionally excluded because
+those products are not present in this backend-only repository. Action
+dependencies are pinned to immutable commits to satisfy the transfer-readiness
+policy.
+
+## Decision ledger: `v0.7.16` through `0.8.11`
+
+| Upstream commit | Decision | OGM rationale or follow-up |
+| --- | --- | --- |
+| `e95178a` Prepare GTM for production cutover | **Ported selectively** | Ported the recursive test route helper needed by FastAPI's lazy `include_router` representation and updated route-registration assertions. BTAA frontend analytics and production configuration remain not applicable. |
+| `1433322` Bump API version to 0.8.0 | Not applicable | OGM product versioning is independent. |
+| `a529b3b` Prepare v0.8.1 release | Not applicable | BTAA release bookkeeping is not imported. |
+| `a17b83e` Fix production feedback delivery default | Not applicable | Recipient and mail defaults are operator-specific. |
+| `a51a018` Fix production sitemap canonical URL | **Ported** | Prevents a mirror from serving sitemap documents generated for a different origin. Ported with OGM hostname coverage. |
+| `97c80d2` Add Turnstile bot exemptions and update Kithe bridge | Defer | Mixed BTAA edge policy and Kithe control-plane behavior. Revisit only if those components enter the supported OGM deployment profile. |
+| `7becdd8` Version bump for v0.8.4 | Not applicable | BTAA release bookkeeping is not imported. |
+| `caf71d7` Fix similar items missing Elasticsearch docs | **Ported** | Uses `exists` instead of a traced `GET` 404 for retired or intentionally unindexed records. |
+| `e6674b4` Bump version to 0.8.5 | Not applicable | BTAA release bookkeeping is not imported. |
+| `7165142` Improve telemetry and Elasticsearch visibility controls | Port selectively | Public/suppressed filtering, mapping checks, and cache-key isolation support the mirror public-read contract. AppSignal and BTAA fallback values do not. Requires a dedicated cross-endpoint PR. |
+| `1ea6609` Bump version to 0.8.6 | Not applicable | BTAA release bookkeeping is not imported. |
+| `d60a24a` Fix bridge relationship sync and indexing refresh | Defer | Primarily Kithe Bridge reconciliation. OGM mirrors use GitHub Aardvark harvests as their correctness path. |
+| `15c1200` Fix AppSignal frontend telemetry isolation | Not applicable | Frontend telemetry and BTAA observability configuration are not part of this backend product. |
+| `a477847` Fix Kithe Bridge deletion reconciliation | Defer | Kithe-specific deletion workflow; evaluate against OGM repository removal and tombstone policy separately. |
+| `9d2eb78` Bump `aiohttp` | Dependency review | Re-resolve against the OGM lockfile and run security/compatibility tests instead of copying one lockfile delta. |
+| `fb4bbbf` Drop Flower from Kamal deployments | Already satisfied | OGM Kamal roles are `web`, `worker`, and `cron`; Flower remains only an optional local Compose service. |
+| `a545109` Handle Bridge tombstone deletes | Defer | Useful design input for deletion semantics, but the implementation is coupled to Kithe Bridge. |
+| `b8098a0` Bump version to 0.8.7 | Not applicable | BTAA release bookkeeping is not imported. |
+| `6f4b73b` Refresh project dependencies | Dependency review | Produce a fresh OGM dependency PR with lockfile, license, vulnerability, and runtime verification. |
+| `721ea3b` Adjust response handling and file checks | **Ported selectively** | The production-database test now accepts both the legacy `error` and FastAPI `detail` missing-resource envelopes, as required by the full CI suite. Broader Slack, admin, and BTAA response-label changes remain deferred. |
+| `93f73d6` Use local Postgres backups in production | Design reference | Mirror backup/rebuild behavior belongs in the OGM operating runbook and secret model, not as a blind BTAA script import. |
+| `0a24422` Bump version to 0.8.8 | Not applicable | BTAA release bookkeeping is not imported. |
+| `d991db3` Bump version to 0.8.9 | Not applicable | BTAA release bookkeeping is not imported. |
+| `ab214d5` Fix GEOMG distribution and asset syncing | Port selectively | Aardvark distribution, reference, asset, and relationship correctness is relevant, but the commit is broad and Bridge-heavy. Split it into contract-focused ports after fixture comparison. |
+| `2d5444f` Fix location filtering for contained resources | **Ported** | Uses document containment for bbox eligibility so a large query retains small fully contained resources. |
+| `bfbd4db` Bump version to 0.8.10 | Not applicable | BTAA release bookkeeping is not imported. |
+| `ac1b700` Fix relationship cache priming visibility | **Ported** | Routes priming through the public relationship service, connects the legacy database pool for in-process warming, and advances the representation cache version. |
+| `78466a2` Fix source relationship direction | **Ported** | Emits canonical `dct:isSourceOf`, removes the legacy inverse during sync, canonicalizes old rows, and deduplicates responses. |
+| `f1f4092` Release v0.8.11 | Not applicable | Backend changes are release-version updates; the named PMTiles rendering fix is in the BTAA frontend, which this repository does not ship. |
+
+## Port verification
+
+The accepted ports are covered by focused tests in:
+
+- `tests/elasticsearch/test_search.py`
+- `tests/services/test_relationship_service.py`
+- `tests/services/test_relationship_sync.py`
+- `tests/services/test_sitemap_service.py`
+- `tests/scripts/test_prime_resource_representation_cache.py`
+- `tests/scripts/test_refresh_resource_caches.py`
+- `tests/utils/route_helpers.py`
+
+The complete backend suite is also enforced by `.github/workflows/ci.yml` on
+pull requests and pushes to `develop`.
+
+Before the next upstream review, fetch `upstream`, choose a new immutable review
+ceiling, append every backend-affecting commit to this ledger, and keep earlier
+decisions intact for auditability.
