feat(cli): scoped maple delete (service, namespace, env) for the local store

[Makisuo]

Why

Feedback on Maple Local: data can't be deleted per run. Deleting from traces leaves about 20 derived tables (trace_list_mv, error_events, service_overview_*, ...) holding the rows, so maple reset was the only clean option. Teams sharing one local Maple across throwaway dev environments need per-service deletes.

What

maple delete --service checkout-pr-42                # preview: per-table counts, exits 1
maple delete --service checkout-pr-42 --yes
maple delete --namespace pr-42 --yes                 # one service.namespace; same-named services elsewhere survive
maple delete --service api --namespace pr-42 --yes
maple delete --service api --env preview-17 --yes
maple delete --service api --before 7d --yes         # age or UTC timestamp, floored to the hour

• Scope: --service, --namespace, or both, optionally narrowed by --env and --before.
• Every table is classified in TABLE_DELETE_PLAN (apps/cli/src/server/scoped-delete.ts). Each declares which of service, namespace and env it can filter exactly; per request a table is:
  • filter when it declares every requested dimension: ALTER TABLE ... DELETE (raw tables via ResourceAttributes; rollups keyed on ServiceName/DeploymentEnv/ServiceNamespace; service map edges match either end).
  • rebuild when it lacks one: the affected hours are cleared (scoped to the dimensions it does key on) and recomputed from surviving source rows, through its own MV bodies in dependency order (so service_operations_minutely -> _hourly and error_events -> error_fingerprints_minutely cascades are wiped and redone), or for the two service map tables by re-running the hourly rollup for sealed hours. Attribute tables and error_fingerprints_minutely have no usable service key and are always recomputed.
  • excluded: tables local ingest never writes (session tables, alert_checks, audit_log, the Null edges ingest table).
• validateDeletePlan checks the plan against the schema manifest for every flag combination (coverage, column existence, filter columns in the sorting key of merging engines, no excluded table fed from deletable data, recompute cascades covered by a downstream recompute of no wider scope). The server refuses to delete on mismatch, and test/scoped-delete.test.ts fails when a table is added unclassified.
• Server-side operation: new POST /local/maintenance/delete, maintenance-token authenticated, run inside the admission gate's exclusive section. /local/query stays read-only.
• Crash safety: a journal (maple-pending-delete.json) is written before the first mutation and resumed at startup or by the next delete.
• Checkpoints: /local/status gains lastDeleteAtMs (optional, backward compatible); the refresh loop no longer skips a tick after a delete.
• Local-only: --remote or a remote-resolved mode is refused before anything is sent.

Reviewer notes

• Archived Parquet is not affected (immutable exports); re-archiving a day after a delete needs --allow-shrink. Restoring a checkpoint taken before the delete brings rows back. Both are documented in docs/local-mode.md and docs/local-telemetry-archives.md.
• Rebuilds only recompute hours every source still fully retains (bundled TTL plus a day of margin); older hours are reported as skipped and age out by TTL.
• Tests: bun run test in apps/cli (654 pass), including native chDB tests for env, whole-service, namespace (same service name in two namespaces, view cascades, rollup recompute), --before and journal resume. Also verified end to end against a scratch maple start with OTLP ingest.

Summary by CodeRabbit

• New Features
  • Added maple delete to preview or delete local telemetry by service or namespace, with optional environment and age or UTC cutoff filters. Deletion is local-only and requires confirmation with --yes.
  • Deletion reports are available in text or JSON. Interrupted deletions can resume automatically.
  • Local status now reports deletion activity, which is considered when deciding whether to refresh checkpoints.
• Documentation
  • Updated local-mode and archive guides to explain deletion behavior, including its effects on live data, archived records, and checkpoints.

Walkthrough

Adds maple delete for local telemetry, a server endpoint that applies scoped deletes and resumes pending work, and checkpoint refresh logic that detects deletion activity.

Changes

Local telemetry deletion

Layer / File(s)	Summary
Scoped deletion plan and execution apps/cli/src/server/scoped-delete.ts, apps/cli/src/server/service-map-rollup.ts, apps/cli/test/scoped-delete.test.ts	Adds schema-validated table strategies for filtering, rebuilding, or excluding tables. Deletion reports counts and skipped hours. Non-dry-run operations journal work before mutation and support recovery. Tests cover plan validation, dry runs, scoped deletes, cutoffs, and journal resumption.
Authenticated server endpoint and recovery apps/cli/src/server/serve.ts, docs/local-mode.md, docs/local-telemetry-archives.md	Adds the authenticated POST /local/maintenance/delete endpoint, exclusive execution, deletion status, and startup recovery. The status response includes lastDeleteAtMs. Documentation describes the command’s effects on the live store, checkpoints, and archives.
Local delete command apps/cli/src/commands/delete.ts, apps/cli/src/cli.ts, apps/cli/test/delete-command.test.ts	Adds and registers the local-only maple delete command. It supports service, namespace, environment, and cutoff selectors, previews by default, and can return a text report or JSON.
Deletion-aware checkpoint refresh apps/cli/src/commands/server-args.ts, apps/cli/src/commands/server.ts, apps/cli/test/server-args.test.ts	Adds storeChangedSince and updates checkpoint refresh to consider ingestion and deletion activity.

🟡 Confidence 3/5 · needs attention
_{quality 100/100 · no findings · tests covered · risk high · 1/1 new units observable}

Warning

This review ended early; what follows is what it established.

Adds a local-only maple delete that removes a service's or namespace's telemetry from the raw tables and every derived table under the admission gate, previewing unless --yes, with interrupted deletes journaled and resumed at server startup. The delete plan is validated against the schema for every flag combination.

• New maple delete --service/--namespace [--env] [--before] command, dry-run unless --yes
• New /local/maintenance/delete route runs the scoped delete inside gate.exclusiveEffect
• /local/status gains lastDeleteAtMs, consumed by storeChangedSince in the checkpoint refresh loop
• resumePendingDelete replays a journaled delete before the server serves

What was checked

• /local/maintenance/delete rejects a missing token before the body is read (serve.ts:962)
• Dimensions are string-escaped before they reach SQL (scoped-delete.ts:184)
• TABLE_DELETE_PLAN is validated against the schema manifest for all six flag scopes (scoped-delete.test.ts:23)

Observability coverage: 1 of 1 changes observable

Change	Kind	Observable	Evidence
/local/maintenance/delete	inbound HTTP route	yes	wrapped in runSpan like the sibling local routes (apps/cli/src/server/serve.ts:1423-1428)

Maple review

🟢 Confidence 5/5 · safe to merge
The changed hunk only re-shapes flag decoding, is exercised by new tests, and changes no request the server receives.
_{quality 100/100 · no findings · tests covered · risk low}

This head turns buildDeleteRequest into an Effect that distinguishes an out-of-range flag from a missing selector, and adds tests for both. The change is small and correct; only flag validation changed since the last review.

• buildDeleteRequest now fails with invalid delete flags on a failed decode, and with the selector message only when neither --service nor --namespace is present

What was checked

• ScopedDeleteRequest bounds (512 chars, beforeMs >= 0, Int) match the new hint text (scoped-delete.ts:165); --before yields whole-second ints or negative values that fail decode
• buildDeleteRequest's only caller is deleteCommand, which now yield*s it, so no caller still expects an Option
• --env "" and a trimmed --service still decode and pass hasSubject (delete.ts:52-57), as the new test asserts
