The coverage denominator the health-by-accounting ratification named for
the vector family — never built until now, and its absence was measured as
the exact outage class it existed to prevent: a migrated store with
canonical vectors and no derived index opened with the vector leg EMPTY,
served [] from vector search with no error, and the report-driven read gate
had nothing to refuse on (the provider's coverage invariant was honestly
unledgered — the denominator was ours to supply).
- getCanonicalCounts() gains vectors: { all } — the count of canonical
nouns holding a REAL vector. Incremented where a vector lands (the
isNew-gated metadata seam for explicit vectors — the same discipline that
keeps HNSW neighbor-link re-saves from inflating counts; a narrow
noteVectorLanded hook for the deferred-embed landing, gated on the
worker's own pre-embed read). Decremented on a proven delete of a
vectored noun; a vector-uncertain delete marks the ledger suspect rather
than guessing (no new reads on the delete path). Recounted by the
sanctioned recount; legacy counts.json derives it once (a deferred noun's
vector file exists with an empty vector, so presence requires one
content read at derivation — never on the hot path).
- The open gate's vector leg: when a health-reporting provider claims
serving while the index holds zero nodes and the ledger proves vectored
canonical rows exist, open BUILDS (narrated) — routed through the
provider's idempotent fillFromCanonical() when exposed (the joint door;
a partial shortfall stays repair()'s operator business), the JS rebuild
otherwise — or fails typed pre-serve. Scoped exactly: bare isReady()
providers, migrating providers, and white-box size stubs open as before.
Pinned end-to-end from the partner gate's probe shape (store with vectored
canonical rows, no derived index, reopen → search serves N, never []),
red-proved against the pre-fix path; the inverse (zero vectored rows) opens
without building and serves [] honestly.

* @module tests/lifecycle/biography
|
|
* @description THE LIFECYCLE LANE — see `tests/lifecycle/README.md` for what
|
|
* this proves and how to run it. One scenario, "the working store": a single
|
|
* brain driven through founding, a working day, a clean restart, a crash, a
|
|
* repair, and a second life, verified chapter by chapter against an
|
|
* independent shadow-model referee (`biographyHarness.ts`).
|
|
*
|
|
* Split into two `it` blocks so a currently-failing later chapter (see the
|
|
* second block's header comment — a live engine finding, not a defect in
|
|
* this lane) never hides the earlier chapters' passing coverage. The two
|
|
* blocks share one brain's directory and one shadow model, run in the SAME
|
|
* fixed order the single scenario always has (`describe.sequential` below
|
|
* exists to say so explicitly, though vitest's own default is sequential
|
|
* within a file) — this is a split for REPORTING clarity, not a reordering
|
|
* or conditional skip of any chapter.
