Claude 98083cd8d6 Design Phase 9 - operator document management
Operators cannot add a document today: ingestion is CLI-only, needs a host
login and a TTY for confirm_header(), /datadisk/ai-docs is mounted read-only,
ai-api has no identity, and nothing in the stack has a role that can write
doc_chunks. This designs the way in, the way out, and control over what is in
the retrieval pool. Design and schema only - no router, worker or UI code yet.

Documents in (16.1-16.9, db/004):
  upload -> pre-scan -> review -> approve -> published, with the header
  confirmation moved from a terminal prompt to a review screen and recorded
  rather than discarded. A CHECK constraint refuses an approved row without a
  confirmed number, revision and effective date, so an API bug cannot skip it.
  Three roles: agent_ro unchanged, uploads_rw writes the queue only, ingest_rw
  writes doc_chunks and has no HTTP surface.

Documents out (16.10-16.11, db/005):
  --supersede needs a revision to keep, so a cancelled procedure cannot be
  withdrawn at all. Adds withdraw (immediate, reversible, audited), restore
  (refused while another revision is live) and purge (off by default). A
  column grant plus a trigger let the web-facing role make a document less
  citable and never more.

The pool (16.13-16.15, db/006):
  pool_enabled, orthogonal to superseded: one is a claim about the document,
  the other about the corpus. Retrieval requires both, so re-enabling a
  withdrawn document does not make it citable. Named profiles and a
  per-request override let a demo trim the corpus without mutating state on a
  shared live host, and every reduced-pool answer carries a banner with the
  document count, following the used_fixture_data precedent.

Two existing defects found and documented while designing this:
  - ai-ingest takes PGUSER=agent_ro from api.env, a SELECT-only role, so the
    Phase 3 command in the README cannot write doc_chunks (16.1).
  - ingest_file() always inserts superseded = FALSE, so `--all` re-ingests a
    superseded revision as live. --supersede survives only until the next bulk
    run (16.10).

One commit rather than three: the upload, withdrawal and pool designs
interleave in the same spec, README and compose files.
