Adds durable PostgreSQL persistence and tenant-scoped reload for the product-owned anonymous participant base record. The change was developed test-first, uses migration 0030 to avoid active migration-number collisions, keeps optional account-link history out of this base-only boundary, and requires exact-head CI plus independent review before merge.

Verification: cargo test --test postgres_participant_base_persistence; cargo test --lib postgres_participant; cargo fmt --all -- --check; cargo clippy --all-targets -- -D warnings.

Superseded

Closed in favor of #250. This head remained c599b0b0ce731ffd2f1808a500a89798b873c11d, eight protected-main commits behind and diverged from current main. Its participant migration/adapter/persistence/recovery-test blobs were reconciled onto exact current main in #250, while stale documentation was rebuilt instead of carrying the old docs/architecture/AS_BUILT_SCHEMA.md conflict-marker residue and outdated protected-main maturity. Do not merge this historical branch in parallel with #250; reviews/checks from this head do not transfer to the replacement.

Merge Risk: 🟡 Moderate · up to a3719

The new persistence migration can store anonymous participant references that the application rejects, causing those identities to fail when reloaded. Update the database constraint and add boundary tests before merging.

Pushed the #81 recovery fixture so this participant-base slice does not fail integration_consumption_claim_deadline_shape: processing restore rows seed claim_deadline_at, and COPY must keep the exact source deadline. TRACEABILITY/as-built updates for the new participant table remain follow-up on this draft. Never self-approve.

Hourly loop: rust FAIL on exact head 51fc7e4f was rustfmt; coverage also missed Database Display/From/source. Pushed ae9fba0d with .err().expect(...) wrap plus missing-relation Database persist/load. Independent last-push review is still required; this comment is not approval.

Exact-head rust/coverage fix on 120b6901: backtick PostgreSQL in rustdocs, name persist conflict-winner and reload-identity guards, and drop the redundant test closure Clippy would hit after rustdoc. Do not merge without independent last-push approval and a re-green exact-head Runtime CI.

Pushed 584da1fb: name conflict-winner lookup and stored-identity reconstruction guards and prove missing/absent/mismatch independently.

Pushed c2e5a8cb: name loaded-base reconstruction so stored-identity mismatch and related fail-closed arms are executed independently of SQL equality.

Clippy required `PostgreSQL` backticks, and persist/load fail-closed
winner/reload branches were unexecuted. Name those guards so exact-head
rust and coverage can pass without suppressing the lints.
Conflict-winner SELECT none/error and stored-identity mismatch were
unexecuted. Name those guards and prove them independently.
The load-path stored-identity `?` stayed unexecuted because SQL equality
cannot produce a mismatch. Name reconstruction so the fail-closed arms
are proven directly.
The eight-field linked-record guard short-circuited after link_history,
leaving later OR arms and the time-only conflict compare unexecuted.
Classify each projection flag, participant-identity mismatch, and
creation-time rebinding through the persist helpers.
Linux llvm-cov left persist/load and the durable-link projection helper
as unused instantiations. Call them from the lib test against a missing
relation and both anonymous and linked records.

Keep anonymous participant-base persistence off protected-main truth
