Adversarial review of the merged OTel instrumentation (#352) surfaced
four issues, all on the enabled path (default-off, so no impact until
tracing is turned on):
- search LLM client was unwrapped, so hybrid/agentic token usage — the
heaviest LLM spend — never reached Langfuse. Wrap it with
UsageRecordingClient when observability is enabled, mirroring
get_llm_client(); graceful keyword-only degradation is preserved.
- set_generation_usage overwrote token counts, undercounting any span
that wraps more than one chat call (the now-wrapped agentic path).
Accumulate instead of replacing.
- recall_hit was emitted for uncalibrated methods (unbounded BM25 /
single-route vector), a near-constant always-hit signal that inflates
dashboards. Gate hit on calibrated methods (HYBRID/AGENTIC); keyword
and vector emit only the raw top_score.
- init_tracing / init_score_sink were not idempotent — a re-init without
an intervening shutdown orphaned the export thread + OTLP socket +
worker task. Tear down the previous instance first (init_score_sink is
now async).

Every business endpoint (memory/*, ome/*, knowledge/*) is now served
under /api/v2, aligning the open-source API with the EverOS Cloud
contract. /api/v1 is retained as a permanent, backward-compatible alias:
the same router objects are mounted under both prefixes, so both resolve
to identical handlers and request/response contracts. Existing /api/v1
integrations keep working unchanged. Infra endpoints (/health, /metrics)
stay unversioned.
Fix the Prometheus request-metric label to build the path from the full
request URL (with path params folded) rather than the route's
router-relative path, so the version prefix is preserved and v1/v2
traffic stays distinguishable.
Docs (docs/api.md, docs/openapi.json), CHANGELOG, and route docstrings
updated to lead with /api/v2. Add test_api_versioning as the parity
guard: every v2 route has an identical v1 twin and vice versa.

FTS indexes built with with_position=True crash lance's optimize/compaction
on lancedb >= 0.32 when merging an unindexed tail (Max offset exceeds length
of values; upstream lance-format/lance#7653). The crash aborts optimize()
including version cleanup, so the index dir grows unbounded until the disk
fills. everos recall is OR-mode BM25 and never does phrase queries, so
positions are never read -- disabling is lossless.
- base: default with_position=False
- infra: migrate_fts_indexes() rebuilds pre-fix indexes once at startup + reclaims orphans
- cascade worker: count consecutive optimize failures, escalate warning->error
Fixes#335.

md-first memory extraction framework for AI agents.
Markdown is the single source of truth; SQLite holds state and LanceDB
provides the rebuildable vector + BM25 + scalar index. The codebase follows
a single-direction DDD layering (entrypoints -> service -> memory -> infra,
with component / core / config cross-cutting) enforced by import-linter.
Engineering surface:
- Coding conventions in .claude/rules/ (path-scoped) and workflows in
.claude/skills/ (/commit, /new-branch, /pr).
- GitHub Actions CI runs make lint + test + integration; pre-commit mirrors
the gates locally (ruff, hygiene hooks, gitlint commit-msg).
- Commit messages follow Conventional Commits, enforced by gitlint.
- make lint also enforces datetime two-zone discipline and OpenAPI drift.
