ingest_file() inserted every chunk with superseded = FALSE, so replacing a
document's chunks reset its withdrawal. One `ai-ingest --all` made every
superseded revision citable again - including the old revision of a procedure -
silently, and only after a bulk run, so a supersede survived exactly until the
next full ingest.
- ingest_file() reads the existing state with superseded_state() before the
delete and carries it through the insert. A withdrawn document is
re-ingested as withdrawn, and logs that it did so.
- --all skips withdrawn documents, so a bulk run does not spend an embeddings
call on a document that will not be cited either way. --include-superseded
overrides it; the chunks still come back withdrawn.
- --restore DOC_NUMBER REVISION is the counterpart to --supersede, refusing
while another revision of the same document is live. Without it the
conservative default would be a dead end - mark_superseded() only ever sets
TRUE, so there was no way back.
- Rule 5 in the module docstring, beside the other four.
Corrects a claim in the Phase 9 design: 16.10 said moving the withdrawn file
out of /datadisk/ai-docs "is not tidying" because otherwise --all resurrects it.
That was true when written and is not now. The guard belongs in the ingest code,
because a rule that depends on somebody remembering to move a file is not a
rule. The move stays as archival housekeeping and is documented as such in
16.10, db/005_doc_actions.sql and README.md.
Phase 3's gate gains the proof: supersede a revision, run --all again, ask the
question that used to cite it.

ai-ingest built its DSN from PGUSER/PGPASSWORD and takes its environment from
~/ai/api.env, where PGUSER=agent_ro - SELECT and nothing else, deliberately,
because it is what the answer path runs as. So
docker compose -f ~/ai-compose.yml run --rm ai-ingest --all
connected as a role that cannot INSERT INTO doc_chunks, and Phase 3 was
unrunnable exactly as the README documents it. Nothing had reached Phase 3 yet,
so nobody had hit it.
The failure would also have landed at the worst possible moment: at the final
INSERT, after the Docling parse, after a person had typed the header
confirmations for every file, and after a billed embeddings call - with a
permission error naming no cause.
- ingest_rw moves to 003_roles.sql, at Phase 1 with the other roles. It is
not a Phase 9 concept; ingestion has needed a writing role since Phase 3
and never had one. 004 keeps only its grants on the upload queue, and its
idempotent role creation so it still applies to an older database.
- ingest.py connects through INGEST_DB_USER / INGEST_DB_PASSWORD, falling
back to PGUSER only for a local shell where one pair is set.
- require_write_access() checks INSERT, UPDATE and DELETE on doc_chunks
before anything is parsed or embedded, and fails with the fix in the
message. Falling back to PGUSER cannot smuggle agent_ro past it.
- Keyword connection parameters rather than a URL: a generated password
containing @ or / breaks a DSN string silently.
- A missing doc_chunks now says "apply 001_schema.sql" instead of raising
UndefinedTable.
Phase 1's gate gains the check that would have caught this: ingest_rw must be
able to write doc_chunks. An ingestion role that cannot write is the same class
of failure as an API role that can - it just surfaces two phases later.
