203a18ae83 feat(observability): OpenTelemetry logs+traces with secret redaction and slog standardization (#290)
* feat(observability): OpenTelemetry logs+traces with secret redaction

Part of #265. Adds opt-in OpenTelemetry (logs + traces) alongside the existing
stderr + opslog pipeline, plus secret redaction on all sinks. Default-off: with
no OTEL_* / SILO_OTEL_ENABLED config, behavior is unchanged.

Bootstrap (internal/telemetry):
- Setup() builds one shared resource, a TracerProvider (parent-based trace-id
  ratio sampler), a LoggerProvider, and the W3C TraceContext+Baggage propagator
  from env. It installs NO MeterProvider — metrics stay on Prometheus, and the
  built-in no-op global MeterProvider keeps the trace instrumentation libs from
  double-emitting. Shutdown is deferred with a flush timeout.
- Logs are bridged via otelslog fan-out (slog.MultiHandler), level-gated by the
  shared LevelVar and best-effort so a failing collector can't break the console
  or DB branches. stderr + opslog stay untouched.

Secret redaction (internal/logredact):
- A slog.Handler masks secret-keyed attributes (password, token, api_key,
  authorization, cookie, ...) — including .With-bound attrs, nested groups,
  secret-keyed group subtrees, and values behind a LogValuer — on the console
  and OTLP sinks, with a no-op fast path when a record has no secret keys.
  opslog.shouldRedact delegates to logredact.SecretKey so all sinks share one
  marker list.

Rotation is infra-managed (no custom file sink): container runtime for stderr,
collector/backend for OTLP, opslog partition-pruning for the DB. Documented in
docs/architecture/observability.md.

Verification: go build ./..., go vet, gofmt -l — clean; go test
./internal/telemetry/ ./internal/logredact/ -race pass.

AI-use disclosure: implemented with AI assistance (Claude Code), including
adversarial reviews that hardened the bootstrap and fixed two redaction leak
paths; reviewed by the author.

* refactor(observability): slog context+component sweep, sloglint gate (phase 3)

Part of #265. Builds on the OTel bootstrap + redaction commit.

Standardizes every log call site onto the context-carrying slog variants so
records correlate with the active OpenTelemetry trace, and locks the standard
in with a machine gate so future code (human- or AI-authored) can't drift back.

- Call-site sweep: converted the remaining slog.<Level>(...) calls to the
  slog.<Level>Context(ctx, ...) form wherever a context.Context is in scope
  (background/init calls with no ctx are left as-is), across 183 files. Applied
  via a type-aware AST codemod. Log levels and message strings are preserved
  verbatim; a component attr (canonical per-package name) is added to direct
  package-level slog calls. Bound-logger calls keep their existing .With
  bindings. The main.go and telemetry package conversions rode with their file
  in the previous commit to keep each file within a single commit.
- Enforcement (.golangci.yml): enable sloglint with context=scope, static-msg,
  key-naming-case=snake, no-mixed-args. After the sweep all four report zero
  violations repo-wide (tests included), so make lint / CI now blocks any
  regression to the non-context form. The gate ships with the sweep because it
  cannot be green until the legacy sites are converted.

Metrics remain on Prometheus; no behavior change to /metrics or Grafana.

Verification: go build ./..., go vet ./..., gofmt -l — clean; sloglint (all 4
rules) 0 violations repo-wide; log levels verified unchanged.

AI-use disclosure: implemented with AI assistance (Claude Code), including the
codemod; reviewed by the author.

* fix(observability): honor per-signal OTLP protocol and secret WithGroup names

Two Codex review findings on PR #290:

- telemetry: OTEL_EXPORTER_OTLP_{TRACES,LOGS}_PROTOCOL now override the
  generic OTEL_EXPORTER_OTLP_PROTOCOL per signal, so mixed collector
  setups (e.g. HTTP logs + gRPC traces) build the right exporter.
- logredact: entering a group whose name is secret-bearing (e.g.
  WithGroup("authorization")) now masks every leaf in that subtree,
  matching how slog.Group("authorization", ...) is masked as a whole.

* fix(observability): address review feedback on telemetry bootstrap

- Telemetry setup failure no longer kills boot: Setup returns usable
  no-op providers alongside the error and main logs and continues with
  telemetry disabled, honoring the best-effort contract.
- Honor OTEL_TRACES_SAMPLER (always_on/off, traceidratio, parentbased_*
  variants); unsupported values fall back to parentbased_traceidratio.
- Attach node identity as semconv service.instance.id instead of the
  non-semconv node.name.
- Rename opslog retention-scope log attrs to target_component/target_level
  so they no longer collide with the canonical component routing key, and
  tag those lines with component=opslog.
- Fix stale levelGated comment casing; use WarnContext in the telemetry
  shutdown defer; document the LogValuer double-resolve on the redaction
  slow path.

QuickandClaude Fable 5 80aff39921 fix(matching): return empty override arrays from split so dry-run preview JSON has [] not null
A whole-folder split only populated root overrides, leaving file_overrides
marshaled as null, which crashed the Split Versions preview render in the
web UI and kept the Split button disabled.

Part of #319 follow-up.

AI-use: implemented with Claude Code.

0fb5afe479 feat(matching): split wrongly merged versions with watch-state reattribution; anchor group keys on provider tags (#319)
* feat(matching): split wrongly merged versions, reattribute watch state, anchor group keys on provider tags

Wrong merges (two titles normalizing to the same title+year key) stacked
different films as fake "versions" of one item with no in-app repair, and
explicit {tmdb-…}/[imdb-…] folder tags could not prevent it because the
content-group key ignored provider IDs entirely. Merges also silently
orphaned all per-user watch state.

- Anchor group keys on structured provider tags: same tag always groups,
  different tags can never merge; untagged files keep title+year keys.
- media_identity_overrides: path-scoped (root/file) forced identities applied
  during group inference, so admin splits survive rescans.
- internal/catalog/reattribute: shared user-state mover — exact moves for
  file-linked rows, evidence-based user_watch_history classification via the
  playback session log, newest-wins progress conflicts; wired into
  rebindItemToExistingItem to stop merge orphaning (with S/E episode mapping).
- POST /admin/items/{id}/split (dry-run = full transaction + rollback, so
  previews are exact), POST /admin/items/{id}/merge, GET /admin/items/{id}/files.
- Web admin: Split Versions dialog (files by folder → candidate search →
  preview → split), Resolve link from ambiguous-roots diagnostics.

* fix(reattribute): classify history before moving session log; cover managed downloads and series-scoped preferences

Review findings on #319, all reproduced against a migrated scratch database:

- moveFileSubset re-pointed playback_history_admin before the history
  evidence query ran, erasing exactly the evidence proving a profile's plays
  were all on moved files — their history stayed behind as ambiguous.
  History classification now runs first; the pre-fix code demonstrably fails
  TestRun_HistoryEvidenceClassification.
- Managed offline downloads (downloads.content_id/episode_id) were not
  remapped on split or merge, stranding rows on the old id. Now moved per
  file on splits and swept per id pair on merges/episode re-anchoring.
- Series merges left user_audio_preferences, user_subtitle_preferences,
  user_series_playback_preferences (series_id-keyed) and the denormalized
  user_home_item_dismissals.series_id behind. All four now move, mirroring
  the provider-merge remap.

All five reattribute DB tests now verified green against PostgreSQL, with
new coverage for managed downloads, subtitle preferences, and dismissal
series ids.
