Switching a remote's backend (base_url) left the previously-cached mutable
metadata (repodata / Release / APKINDEX) served until TTL expiry, pointing
at the old upstream. cache.FlushRemote existed but was wired to nothing.
- Inject a MetadataFlusher (satisfied by *cache.Redis) into RemotesHandler.
- On update, read the existing remote first, then after a successful DB
update flush the remote's cached metadata when base_url changed so the
next request re-fetches fresh from the new upstream.
- A flush failure is logged as a warning and does not fail the request; the
DB update already landed.
- Add tests: base_url change flushes exactly once, an unchanged base_url
does not flush, and a flush error still returns 200.
## Why
This stacks the Debian/apt analog of `github_rpm` on top of the deb local+remote work (#111). It lets a GitHub repo's `.deb` release assets be consumed as a real apt repository without artifactapi ever precaching whole packages: it derives per-asset control metadata from a ranged prefix fetch, synthesizes a flat apt repo from the cache, and redirects the actual `.deb` downloads to a backend `releases_remote` (the generic github.com remote).
Base is `benvin/deb-local-remote` (stacked) to keep the diff atomic.
## How
- Adds `github_deb` to the package-type enum and validity map.
- Adds the `github_deb` provider mirroring `github_rpm`: `ServeRemote` serves `Packages`/`Packages.gz`/`Release`, returns 404 for `InRelease`/`Release.gpg` (unsigned, consumed via `[trusted=yes]`), and 302-redirects `*.deb` to `{proxyBaseURL}/api/v1/remote/{releases_remote}/{path}`; cold-start prime with a retryable 503.
- `deriveAsset` ranged-GETs the front of the `.deb` (an `ar` archive), locates and fully reads `control.tar.*`, and parses the control paragraph — doubling the range if the control member is truncated. The Packages `SHA256` comes from the GitHub asset `digest` when present, else a one-time full stream; `MD5sum` is left unset (apt verifies against SHA256 under `[trusted=yes]`).
- Adds a `github_deb` background Syncer (own worker pool, shared rate limiter, deduped queue) with per-remote DB-lease-gated scans so only one replica scans per window.
- Adds the `github_deb_sync_state` table plus `ListGitHubDebRemotes` / `ClaimGitHubDebSyncLease` / `ReleaseGitHubDebSyncLease` DB helpers, kept separate from the rpm ones.
- Primes `github_deb` remotes on create and runs the deb syncer alongside the rpm one; prime-on-create is routed by package type.
- Reuses the deb apt-index generators and control parser; the Packages generator now skips empty hash lines so a SHA256-only entry is valid.
## Notes / deviations
- **Filename convention:** the `Filename` stored in the Packages index is the **github-relative** asset path (same as rpm's `assetPath`), not `pool/<asset>`. This is required for the `.deb` 302 to `{releases_remote=github}/{path}` to resolve against github.com; it still matches the `*.deb` redirect rule.
- **GitHub client helpers** (releases pagination, ranged GET, auth headers) are duplicated into the deb package rather than shared, because the rpm equivalents are unexported in `package rpm` and the task requires not modifying the rpm provider.
- `go build`, `go vet`, `go mod tidy`, and `make test` (`-race`, incl. the Postgres lease integration tests) all pass; pre-commit clean.

## Why
Builds on #107 (merged), which derives `github_rpm` RPM metadata lazily on the
client request path, single-flighted per replica. Two problems remain: the
derive still happens per replica, so across a multi-replica deployment the same
releases are scanned and re-derived N times, multiplying GitHub queries; and a
cold cache blocks the first request on a full derive. GitHub's rate limits are
low (~60/hr unauthenticated, ~5000/hr authenticated), so this needs a single
coordinated syncer with a shared rate limit and conditional requests.
## How
- Add a single per-process background syncer (started at boot, cleanly stopped
on shutdown) that owns a deduped/coalescing work queue, a worker pool, and one
global token-bucket rate limiter (`golang.org/x/time/rate`) bound onto the
github provider so every GitHub call (releases list + each ranged asset GET)
acquires a token first.
- Re-check each `github_rpm` remote for new/changed releases on its existing
`mutable_ttl` cadence; derive only new/changed assets incrementally and prune
assets that disappear upstream. Repodata is served from primed DB rows.
- Prime metadata in the background on remote creation; the create call returns
immediately.
- Send the stored releases-list `ETag` as `If-None-Match`; a `304` derives
nothing and is not counted against GitHub's rate limit, so an unchanged repo
is nearly free.
- Coordinate replicas through a `github_rpm_sync_state` row (`last_synced_at`,
`etag`, `sync_lease_owner`, `sync_lease_expires`): a periodic scan runs only
for the replica that atomically claims the lease, bounding total GitHub load
to ~once per `mutable_ttl` regardless of replica count; the ETag is shared
through the same row.
- Keep the request path fast: serve current cache, enqueue a prime on an empty
cache, and return a bounded wait then a retryable `503` rather than blocking
on a cold derive.
- Add `GITHUB_SYNC_RATE` / `GITHUB_SYNC_BURST` / `GITHUB_SYNC_WORKERS` /
`GITHUB_SYNC_POLL_INTERVAL` config with conservative defaults (1 req/s, burst
5, 3 workers, 60s tick) and document the syncer in the README.
## Tests
- Unit (httptest, Range/ETag-aware fixture): `304` releases response derives
nothing; incremental derive fetches only the newly added asset; the shared
limiter caps request rate; work-queue enqueues coalesce to one job; prime
enqueues a job; a held lease stops a second replica from scanning; cold-start
serves `503` while warm cache serves `200`.
- DB integration (testcontainers postgres): the real lease SQL — one holder at a
time, recency gate blocks a too-soon periodic re-claim, prime (freshness 0)
bypasses recency but respects a live lease.
- Docker e2e re-run: `dnf install dotvault` works; prime-on-create derives in the
background at ~1 req/s (global limiter); `dnf makecache` served fast from the
priming cache (no cold block); clean shutdown mid-scan, no panics.
## Notes
- Reuses `mutable_ttl` as the check interval (no new per-remote field), per brief.

Follow-up to #99.
## Why
Evicting or deleting a local RPM removed the \`local_files\` row but left its \`rpm_metadata\` behind. Since generated repodata is built from \`rpm_metadata\`, \`primary.xml\` kept advertising a package that no longer exists, producing 404s for clients that tried to fetch it.
## Changes
- Add \`PostDeleteHook\` and \`MetadataDeleter\` provider interfaces (symmetric to the existing \`PostUploadHook\`/\`MetadataStore\`), plus a \`DeleteRPMMetadata\` DB method.
- Implement \`AfterDelete\` in the RPM provider to drop the metadata row for the deleted file.
- Route both local delete paths — the new \`evictLocal\` and the existing files handler's \`remove\` — through a shared \`deleteLocalFile\` helper that removes the file then runs the provider's post-delete hook. Non-RPM providers have no hook, so nothing changes for them.
- Cover the cleanup with a dockerised test.

## Why
Local repos store uploaded files in the \`local_files\` table, whereas remote/proxy repos cache into the \`artifacts\` table. The shared **Cached Objects** page always queried the artifacts table via \`/api/v2/remotes/{name}/objects\`, so files uploaded to a local repo (e.g. an internal RPM) were fully stored and servable but showed as **0 objects** in the UI.
## Changes
- Add \`ListLocalArtifacts\`, joining \`local_files\` with \`blobs\` and returning \`models.Artifact\`-shaped rows (size from the blob; access/fetch counters zero and timestamps derived from \`created_at\`, since local files track no access).
- Add \`LocalRoutes\` to the objects handler: \`listLocal\` reads \`local_files\`, \`evictLocal\` deletes via \`DeleteLocalFile\`. Extract shared page/per_page parsing into \`pageBounds\`.
- Mount \`/api/v2/locals/{name}/objects\` (GET + DELETE) in the server.
- Add \`listLocalObjects\`/\`evictLocalObject\` to the UI client and route the Objects page to them when viewing a local repo.
- Cover the listing and eviction paths with a dockerised test.
## Notes
Generated \`repodata/*\` files are not listed — they are produced on the fly from \`rpm_metadata\` and never stored in \`local_files\`, which matches how the repo serves them.

Raises statement coverage of the core packages (all of `internal/` except the interactive `tui/`, plus `pkg/`) from **8.7% to 90.1%**.
## Approach
- **Pure-go unit tests** for all providers, virtual mergers, classifier, config, auth, models, and the API client (httptest).
- **Testcontainers-backed** tests (new `internal/testsupport` helper: Postgres/Redis/MinIO, Ryuk disabled) for database, storage, cache, the proxy engine, the GC, and a full-stack `server` test that drives the whole HTTP API. These `t.Skip` when Docker is absent so `go test` still runs locally without it.
## Measuring
```
go test -coverpkg=./internal/...,./pkg/... -coverprofile=cover.out ./internal/... ./pkg/...
grep -v /internal/tui/ cover.out | go tool cover -func=/dev/stdin | tail -1 # 90.1%
```
Run with `-p 1` (containers are heavy).
## Notes
- The interactive `tui/` package and `cmd/main` are excluded from the target per the agreed scope.
- Some defensive error branches are covered via fault injection (closed DB pool, killing MinIO mid-upload).

Fixes#72
## Why
`compilePatterns` silently discards any pattern that fails to compile. A typo in a blocklist entry therefore turns a deny rule into a no-op — a fail-open with security impact.
## Changes
- Add `Remote.ValidatePatterns`, which compiles every pattern list (patterns, blocklist, mutable/immutable patterns, ban_tags) and returns an error on the first invalid regex.
- Reject invalid patterns with 400 at remote create and update time.
- Unit test for valid and invalid patterns.
## Validation
- `go test ./pkg/models/` and `make e2e` pass.

## Summary
Move package-type-specific local repo logic out of centralized handlers into provider packages via optional Go interfaces.
**New interfaces in `provider` package:**
- \`LocalUploader\`: \`ValidateUpload(filePath) → (storagePath, contentType, error)\` + \`UploadResponse(...)\`
- \`LocalIndexer\`: \`ServeLocalIndex(w, r, files, repoName, path) → bool\` + \`GenerateLocalIndex(ctx, files, repoName, path) → ([]byte, error)\`
- \`FileStore\`: \`ListFilesByPrefix\` + \`ListPackages\` (implemented by database.DB)
**Providers implement these interfaces:**
- PyPI: upload validation (wheel/sdist naming), simple index serving + generation
- Terraform: upload validation (provider zip naming), mirror protocol serving
**Handlers simplified to generic dispatch:**
- \`local.go\`: type-asserts to \`LocalUploader\`, falls back to generic upload
- \`proxy.go\`: type-asserts to \`LocalIndexer\`, falls back to raw file serving
- \`engine.go\`: type-asserts to \`LocalIndexer\` for local virtual members
Adding a new local repo type (e.g. RPM) = implement the interfaces in its provider package. Zero handler changes.
## Test plan
- [x] Build + unit tests pass
- [x] E2E: PyPI local upload → simple index → uv pip install (smoke test after refactor)

Introduces repo_type (remote/local) as a separate axis from package_type
so that any package type can be hosted locally. A terraform local repo
is package_type=terraform + repo_type=local.
- Remote model gains RepoType field (defaults to "remote")
- Database schema adds repo_type column with migration for existing DBs
- V1 proxy adds /api/v1/local/{name}/* route for serving local files
- V2 upload via PUT /api/v2/remotes/{name}/files/{ns}/{type}/{file}.zip
validates filename matches terraform-provider-{type}_{ver}_{os}_{arch}.zip
and returns 409 on duplicate (no overwrites)
- index.json and {version}.json are computed on-the-fly from uploaded zips
rather than stored as separate files
- V2 create validates repo_type and requires base_url only for remotes
