feat(observation): define immutable PostgreSQL schema snapshot contract

[seonghobae]

Fresh Source Observation authority — 2026-09-11

• Actual exact head is 287165d399c5f54d6c4b4aa3c15497b47de8244b, OPEN Draft/mergeable on Client feat(client): add offline semantic release admission contract #5 6873ec0c0a701b2c59f3e0785d48d8739f019d5b.
• The prior body coordinate 6c1157ef... is historical; subsequent forward commits retained the Source Observation source tree while repairing the shared product-gap baseline. Current 287165d... restores the detached-artifact Client boundary in that baseline and does not constitute fresh Source Observation runtime acceptance.
• Representation successor feat(observation): add domain-separated v3 successor schema representation #45 is now exact 6b2a8f555725dc79f60432afbc492d6005290a4a, stacked directly on this exact feat(observation): define immutable PostgreSQL schema snapshot contract #6 head and intentionally restored to Draft. Review 5174185818 records two current repair findings: (1) first-class index evidence/coordinate/digest semantics required by this P0 are absent, and (2) DomainObservation.base_type is not resolution-validated even though column type bindings are. feat(observation): add domain-separated v3 successor schema representation #45's body has been corrected so it no longer claims completion of the full P0.
• Preserve feat(observation): add domain-separated v3 successor schema representation #45's valid relation-kind/comment/domain/enum/schema-coordinate/type-binding work. Repair forward with executable REDs and minimal causal fixes; do not close, flatten, force-push, destructively rebase, or transfer its pre-repair local GREEN.
• Concrete PostgreSQL transport remains sequenced after a complete representation successor is exact-head GREEN, including first-class indexes and exact domain-base binding.

The detailed 2026-09-10 checkpoint below is retained as historical evidence and requirements context. Where its “current head” wording conflicts with the fresh block above, the fresh block is authoritative.

Historical Source Observation checkpoint — 2026-09-10

Exact head 6c1157efad5d2e4258330d6485ff2ea980ae331b; OPEN Draft on current Client #5 6873ec0c0a701b2c59f3e0785d48d8739f019d5b. Source Observation was non-force reconciled at b614fddc3331365da84733f660a429ed71b83182, preserving pre-restack source 331f8edcd7cebb1719e5cea3187f3848ce7b9e71 and current Client. Successors through 77c143d..., b9b55d0..., 18d8820..., and current 6c1157e... change only docs/product-technical-gap-baseline.md; production/test/contract/dependency source is unchanged.

Protected central .github/main is cb0872c9a20d5584703dffacca65c096fc034c6c. Fresh authority comparison keeps .github#2040@6706c231ab06a3c91c43fdb5b989cfcd79fff593 on historical base 7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db, diverged 144 commits ahead / 32 behind current protected truth; #2051 558693e... is likewise 18 ahead / 32 behind. Stacked #2056 69ae472... is OPEN Draft/mergeable on #2051. Their valid producer/handler, exact identity and atomic-wake deltas must be preserved through ordinary non-force reconciliation; old-base execution/review evidence does not become current-base acceptance.

Exact-current execution/review evidence resets on this documentation successor. Pre-restack 331f8ed... locally executed Rust 1.98: 132 tests across 42 suites including two doctests, fmt, strict all-target/all-feature Clippy, warnings-denied rustdoc, release, Product CI contract/schema/fixture checks, normalized owned coverage 228/228 functions, 2,026/2,026 regions and 194/194 branches. These are historical lineage results, not 6c1157e... acceptance.

Retained bounded-context contract

Source Observation owns bounded request admission, exact source/schema/resource authorization, immutable observed relational facts, source-content digest identity, evidence locations and receipts. It does not own credentials, source-system business truth, semantic inference, provider runtime objects, publication authority, or foreign product truth.

AuthorizedObservationRequest is single-use at the execution seam; retry requires fresh authorization. Source key plus opaque connection-policy binding identifies the authorized mapping without carrying connection material. Stale binding fails before source access. One non-resetting operation budget begins before registry/policy authorization and continues through adapter execution/cancellation. Complete-or-fail snapshot construction is required.

Current v2 evidence preserves exact table/column/constraint metadata including owner-computed digest, exact UTC provenance, qualified table identifiers, column comments, PK/UNIQUE/FK/CHECK evidence, UNIQUE null-comparison state, FK reference behavior plus targeted SET NULL/SET DEFAULT columns, and observed validation/enforcement state. Historical receipt versions are never rewritten.

P0 PostgreSQL 18 representation before transport

Current source cannot losslessly represent relation kind, relation/table comments, first-class index evidence, or schema-scoped domains/enums. Its public ObservationLocation requires a table coordinate and exposes only Table/Column/Constraint kinds; canonical_location() always traverses /schemas/{schema}/tables/{table}. The current digest family is explicitly conceptweave.postgres_schema_snapshot.v2 and hashes table/column/constraint evidence only.

Review 5160201671 requires a backward-compatible versioned/tagged successor coordinate/receipt seam for genuine schema-scoped objects. Do not make current table_name() -> &str nullable or invent a sentinel table. Historical v2 table/column/constraint coordinates keep identical meaning. Type-only schemas must be directly checked against the exact AuthorizedObservationRequest schema allowlist before immutable snapshot/receipt side effects.

Review 5160252371 adds a separate semantic-identity prerequisite. ColumnObservation currently stores only data_type: String. The successor must keep display text separate from identity, bind each column to exact built-in/qualified source-type evidence, distinguish same-name types across schemas, and never infer type identity from search_path.

The representation must preserve relation kind; comments; indexes including key versus INCLUDE attributes, expression positions, partial predicates, NULL uniqueness and readiness/validity/liveness; domain qualified base type, applicable typmod/array dimensions, collation, NOT NULL/default state and domain CHECK constraints; and enum label membership/order. pg_get_constraintdef, pg_get_indexdef and pg_get_expr text is server-reconstructed evidence, not original DDL. Catalog OIDs may join one captured catalog transaction but are not governed semantic identity.

RED before representation source

Executable RED precedes production representation code:

• a frozen historical v2 fixture reproduces the original v2 digest and table/column/constraint coordinate meaning exactly;
• otherwise-identical successor snapshots differing in one material PostgreSQL fact have distinct v3/equivalent identities;
• every new evidence kind has an exact verified receipt coordinate;
• unauthorized domain/enum-only schema fails before immutable snapshot/receipt side effects; an authorized type-only schema succeeds;
• same-name types in different allowed schemas remain distinct and columns resolve to their exact qualified type coordinate even if display text is identical;
• enum label membership/order and material domain base/default/null/collation/check semantics alter successor identity;
• fake table-scoped type coordinates fail closed;
• input-order permutations of identical complete evidence remain digest-identical.

The active baseline, Issue #2 and reviews 5160201671 / 5160252371 carry this acceptance contract.

Concrete PostgreSQL adapter boundary

Only after the representation/version/authorization/type-binding slice is exact-head GREEN may transport be admitted. Use a maintained patched Rust PostgreSQL driver pinned by immutable lock coordinate and passing cargo-deny/SBOM review. Resolve least-privilege credentials only for exact authorized key+binding; reject stale binding before credential/source I/O. Use one explicit REPEATABLE READ READ ONLY catalog transaction and preserve exact-schema pg_catalog evidence. Connect, transaction setup, catalog queries and cancellation cleanup consume the same remaining operation budget. Enforce row/byte/concurrency ceilings and complete-or-fail capture. Freeze an anonymized GRC-shaped conformance fixture without copying governance-risk-compliance source or querying its application tables through hidden coupling.

Upstream hosted gate

Product bootstrap #35 is exact 9bb82f041483cb4e0cf1aa1f5450b413309f9a05, OPEN/non-Draft/mergeable against protected ConceptWeave main. Its unchanged exact head remains the central CodeQL rollout/settlement consumer canary; leaf churn is not corrective evidence. Protected central .github/main is cb0872c9a20d5584703dffacca65c096fc034c6c.

.github#2040@6706c231... and .github#2051@558693e... retain useful CodeQL producer/handler/identity repairs but are both rooted in historical main@7fd571db... and diverged from current protected truth by 32 commits. #2051's live authority identifies a deterministic rollout/bootstrap mismatch because repository_dispatch executes the protected default-branch handler while the PR-head client expects the newer {base_ref, base_sha} identity. A versioned backward-compatible protected handler must land first; then #2051 is reconciled non-force onto current protected truth and its client switched only after the compatible handler exists. #2056 69ae472... remains OPEN Draft/mergeable stacked on #2051 and must adopt that repaired exact successor, not independently restack to protected main.

After the protected handler bootstrap and current-main reconciliation, obtain exact central terminal evidence and qualifying independent review, integrate normally, then obtain fresh unchanged-head #35 CodeQL/review acceptance. Only after #35 and Foundation prerequisites land should this unchanged Source Observation lane regenerate its own hosted acceptance. No manual/no-op rerun or ConceptWeave leaf churn can repair the central owner contract.

Merge gate

Keep Draft. Require the representation slice itself to follow RED -> minimal causal repair -> fresh exact-head Rust 1.98 workspace/fmt/strict Clippy/rustdoc/release/owned-production 100% coverage. Then require applicable hosted Product/security/dependency checks, qualifying independent review and zero valid unresolved findings after protected prerequisites. Do not transfer predecessor GREEN or add the concrete adapter first.

No self-approval, review dismissal, force push, destructive rebase, admin bypass, gate weakening, provider bypass, synthetic status, mutable supplier dependency, Zotero mutation, premature semantic publication, or predecessor-evidence transfer.

Child #46 is now exact 987c83333b36807f895a491e6e2ebe1611ec3704 with PostgreSQL 18 NOT NULL aggregate source repair ordinary-forward (c5ac66ff...) plus duplicate-family/reverse-order edge contract (e60cfec3...) and code-current baseline. Status is NOT_NULL_CONSTRAINT_SOURCE_REPAIRED / ACCEPTANCE_PENDING, not GREEN. Do not partial-cherry-pick or duplicate this child delta. Required sequence remains unchanged-head #46 native/hosted GREEN -> complete ordinary/non-force #45 adoption -> fresh #45 GREEN -> complete #6 propagation.

Stack authority update only; keep #6 source unchanged. Representation parent #45 remains exact 6b2a8f555725dc79f60432afbc492d6005290a4a; active Source Observation child #46 is now exact cc6c4af9342384e60004430649725a3d220461a4, including the PostgreSQL 18 NOT NULL coninhcount signed-int2 source-domain repair. No partial cherry-pick or duplicate implementation into #6. Sequence remains #46 exact-head GREEN -> complete ordinary/non-force #45 adoption + fresh GREEN -> complete #6 propagation.

Representation child authority is now #46 exact 868464850d0b0f967d06eac71fc3328eb461441f, still SOURCE_REPAIRED / ACCEPTANCE_PENDING. Latest repair corrects the PostgreSQL 18 PK-backed attnotnull case without synthesizing explicit contype='n' rows. Preserve #6 source unchanged: #46 unchanged-head GREEN -> complete ordinary/non-force adoption into #45 -> fresh #45 GREEN -> complete propagation here. No partial cherry-pick or duplicate implementation.

Correction to prior coordination review 5190464054: the claim that PostgreSQL 18 permits a PRIMARY KEY-backed attnotnull without a separate first-class NOT NULL row was based on superseded April 2024 development state. Current child #46 exact db2d1c8f90a4d6626d1b0e2ce3d83a6dc22f4666 restores complete bounded NOT NULL-row coverage via corrected RED d4df54d9... and production repair 0cdd4fd3...; doctoring 6c37275c... records the chronology. Preserve #6 source unchanged: #46 unchanged-head GREEN -> complete ordinary/non-force #45 adoption -> fresh #45 GREEN -> complete propagation here.

Fresh coordination authority: keep #6 source unchanged at 287165d399c5f54d6c4b4aa3c15497b47de8244b. Representation parent #45 remains 6b2a8f555725dc79f60432afbc492d6005290a4a; complete child #46 remains db2d1c8f90a4d6626d1b0e2ce3d83a6dc22f4666, NOT_NULL_CONSTRAINT_SOURCE_REPAIRED / ACCEPTANCE_PENDING. Central Noema owner has advanced ordinary-forward to .github#2079@9dccfaa0776950498e557390a2fa8d6c34e0baf4: its finding↔confirmed-probe schema/prompt/validator RED is source-repaired, while fresh exact-head hosted acceptance is still pending. Do not partially adopt #46, duplicate the central contract, or transfer predecessor evidence. Required order stays #46 unchanged-head GREEN → complete ordinary/non-force #45 adoption + fresh #45 GREEN → #6 propagation.
