Today's `SketchStore` is keyed by `aggregation_id` but does not know -//! anything about the schema (sketch type, parameters, grouping labels, -//! window) attached to that id beyond what's in `StreamingConfig`.

This is the §6.3 "no writes after -//! retirement" guarantee. -//! 3. **A place to attach derived metadata** — most importantly the -//! `AccuracyProfile` (§6.4) so the query path can return error bounds -//! without recomputation. -//! -//! ## What this file covers -//! -//! Phase 2a added the lifecycle + registry: -//! -//! * `AggSchema` struct with the lifecycle fields populated from -//! `AggregationConfig` + a `created_at` timestamp. -//! * `AggStatus` enum: `Active` / `Retired` / `Expired`, derived from -//! `retired_at` and `expires_at` plus the wall clock. -//! * `SchemaRegistry` — an in-memory map keyed by `agg_id` that the -//! ingest path consults. Built from the current `StreamingConfig` -//! snapshot at construction; reconciled event-driven by the -//! `POST /api/v1/streaming-config` swap handler. -//! -//! **§7 schema timeline read API:** -//! -//! * `TimelineSegment` + `TimelineCoverage` types. -//! * `SchemaRegistry::timeline_for_metric(metric, t1_ms, t2_ms)` -//! returning the non-overlapping, time-ordered segments that cover -//! `[t1, t2]` for a given metric. Derived on-demand from registry -//! state — no separate index to keep consistent. -//! -//!

Specifically: * `storage_engines/mod.rs` no longer re-exports `AggSchema` / `SchemaRegistry` (only `AggStatus` remains). * `BackfillService` and `BackfillWindowProcessor` drop their `schemas: Arc` field; constructors lose the `schemas` parameter. * `BackfillRegistry::create_checked` swaps its `&SchemaRegistry` + `agg_id` parameters for `&AggregationConfig` + `created_at_ms: u64`. The caller (currently the HTTP handler in drivers/) already has both on hand from its `StreamingConfig` snapshot. The `CreateError::UnknownAgg` variant is retained for HTTP error mapping but is no longer produced by `create_checked` itself — the caller proves the agg exists by holding its config. * Tests that previously dereferenced `schemas.get(agg_id) .created_at_ms` now stamp their own wall-clock millis via a local `now_ms()` helper, matching the registry's own helper. * `create_checked_rejects_unknown_agg` is removed (its case is unreachable in the new signature). The data_plane crate still has ~10 errors outside this slice's scope (precompute_engine / query_engines / drivers / controller) that sibling agents in the parallel retirement big-bang own.

The legacy `SchemaRegistry` type was deleted upstream by the schema retirement big-bang; this slice closes out the consumers in `drivers/query/servers/http.rs`. * `HttpServer` / `AppState`: delete the `schemas: Option>` field, the matching `with_schemas` builder, and every clone site (both `run` and `start_test_server`). * `POST /api/v1/streaming-config`: drop the legacy `schemas.reconcile(snap)` path entirely; only the sid-level `lifecycle::reconcile_from_streaming_config(&SketchStore, &cfg, DEFAULT_RETIREMENT_RETENTION)` survives. Response shape changes: `schemas_created` / `schemas_retired` → `sids_retired: [...]` (no `added` — sids are minted lazily by the ingest path on first write). * `GET /api/v1/db/schemas`: same path, sid-level body. Returns `count` + `schemas: [{sid, metric_name, status, first_seen_unix_ms, retired_at_ms, expires_at_ms, group_by_keys, agg_kind}]`. Empty catalog returns 200 + empty array (no more 503). * `POST /api/v1/db/schemas/:sid/retire` (was `:agg_id`): `SketchStore::force_retire(sid, DEFAULT_RETIREMENT_RETENTION)`. * `POST /api/v1/db/schemas/:sid/expire` (was `:agg_id`): `SketchStore::force_expire(sid)`. * Backfill handler: drop the inner `state.schemas` guard and pass `state.sketch_index.as_ref()` to `BackfillRegistry::create_checked` — the sibling backfill slice owns the `&SchemaRegistry → &SketchStore` parameter swap on `create_checked` itself. * Tests: rewrite `setup_test_server_with_hot_reload_and_schemas` → `setup_test_server_with_hot_reload_and_sketch_index` and `setup_test_server_with_backfill_and_schemas` → `setup_test_server_with_backfill_and_sids`. Add a `register_precompute_sid` test helper. Rewrite `test_streaming_config_swap_drives_schema_reconcile` → `_sid_reconcile` (asserts on `sids_retired`), drop the `_without_schemas_still_succeeds` test (the `schemas` notion is gone entirely) and replace with `_response_shape_with_empty_catalog`. Rewrite `test_get_schemas_returns_active_and_retired_with_status_filter` for the sid body shape; add `test_post_schema_retire_and_expire_endpoints_drive_sid_catalog`. Re-target the two timeline tests at the new sketch_index helper. The route paths `/api/v1/db/schemas{,/:sid/retire,/:sid/expire}` are kept under their existing `schemas` prefix to avoid breaking external callers; only the `:agg_id` path segment was renamed to `:sid`. `AppState` no longer holds a `schemas` field; `main.rs` will drop the `.with_schemas(...)` builder call in its sibling slice.

Rewired the handler to look up the agg-config from the hot-reload streaming-config snapshot (404 on miss) and derive `created_at_ms` as the earliest live `first_seen_unix_ms` from the sid catalog, falling back to wall-clock-now when no sid has ingested data yet. Test fixture `setup_test_server_with_backfill_and_sids` now builds a `StreamingConfig` + `HotReloadStreamingConfig` matching the active agg_ids so the lookup succeeds. 2. `drivers/ingest/otel.rs` `flush_barrier_drops` — X4 deleted `IngestState::record_barrier_drop` (the §6.3 counter was neutered in PR #187), but the helper was still calling it. Stubbed the helper to log-only. 3. `precompute_engine/output_sink.rs` test — `sketch_db::schema` path was hardcoded; switched to the new `sketch_db::lifecycle::AggStatus` location. 758/758 lib tests pass; 5 ignored.
