feat(calibrate): the search bench has a --json form - #226
Conversation
`--search --json` hard-errored, which left the search half of process rule 5's transfer check unscriptable: the evidence bar's title/nonsense verdicts and the per-hit tail family edges could only be scraped out of the table, so sweeping them across several real vaults — and joining those readings with the corpus windows `make eval` prints — was blocked (GH #219). The block is gone and a `search` key sits beside the discovery object. It follows the same re-derivability convention: the summaries the table prints are left to the consumer and what they were computed *from* is emitted instead — per probe (title and nonsense) the query, coverage, best-cos, the **engine's** own `vouched`, its own note's rank, and every served row's provenance (`path`, `bm25_rank`, `cos`) — plus the derived tail-family edges, which are an extremum over the whole positive pile rather than a number to read off a row. `null` means `--search` was not asked for, which is a fact about the invocation, not about the vault. Keys are additive: the discovery object is byte-identical, verified by diffing both objects on a real-model vault. The text block and the object are now two renderings of one `SearchReading` rather than two computations, so a sweep and a human cannot be looking at different numbers. The reading is taken before anything is printed in JSON mode, so a model that fails to load is an error rather than a half-written object on stdout; in text mode the table still prints first and the embedder loads after it. Verified against the real model on a bge-embedded vault: the text output is byte-identical to the pre-change binary, and every value in the object matches the block it replaces (the fake-embedded, no-calibrated-bar path too — the model-free function-word reading is emitted, the judged halves are `null`).

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to The change adds structured search results without altering existing text output or introducing a new execution boundary. The remaining concerns are limited to documenting null behavior and clarifying an optional schema shape, so no actionable merge-blocking risk remains. Sequence Diagram(s)sequenceDiagram

PR #226 review: `bar`, `positives`, `negatives` and `tail` all went `null` together when the active model has no calibrated bar, leaving a consumer to test four keys or pick one arbitrarily. They exist together or not at all, so they now nest under the `Option` that decides it — one `judged` key to branch on, the same shape the reading already has in the type. The function-word weights stay outside it: that half is model-free and is read either way, which is the distinction the flat shape blurred. `docs/evals.md` says so, so a sweep script expects the null before it meets one. Verified on both paths: a bge-embedded vault (judged present, bar and all three piles under it) and a fake-embedded one (judged null, function words still there).
