docs(operator): mark July-8 ingestion/tenancy batch verified live

[BigSimmo]

Summary

Stamps the July-8 batch operator runbook as verified live. Closes the verification
half of task 1.1 (apply + verify PRs #380/#405/#408/#409 on production).

Docs-only — no code, schema, migration, or behavior change. The migration files
themselves are unchanged.

What was verified (read-only, against production Clinical KB Database sjrfecxgysukkwxsowpy)

All six batch migrations were already applied on live (apply = no-op; live history
carries them plus ~15 later migrations). Batch probes replicated as read-only SQL — all green:

• retrieval_owner_matches fail-closed truth table (NULL→false, sentinel/owner isolation correct)
• jsonb_merge_deep deep-merges (R5, fix(ingestion): R5 — deep-merge document metadata instead of full replace #408)
• complete_ingestion_job accepts p_worker_id lease fence (R1/R2, step 2)
• R17 ingestion_jobs_one_open_per_document_uidx — partial-unique on (document_id) WHERE status IN (pending,processing), indisvalid/indisready true, queue 0/0

Clinical governance note

No ingestion / answer-generation / retrieval / access / privacy code is touched — this PR
only edits an operator markdown doc. Verification was performed read-only via the Supabase
connector; nothing was written to the database. The one retrieval-affecting migration
(retrieval_owner_matches fail-closed) was proven correct on live and its sentinel path — the
one the golden eval exercises — is unchanged.

Remaining (not in this PR)

Ingestion worker redeploy (Railway) so R5 merge + p_worker_id fences are active
end-to-end — an operator/deployment step, low-urgency (worker code already passes p_worker_id).

Warning

Review limit reached

@BigSimmo, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 33 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
