A raw request contains only a bounded opaque source registry key (at most 128 bytes, lowercase multiword `snake_case`), an explicit non-empty exact-schema allowlist, a caller-selected authorization-metadata budget, and positive operation/statement-timeout, row, byte, and concurrency execution ceilings. `ObservationRequestBudget` itself is bounded before registry access by canonical product-level caps of 4,096 exact schema identifiers and 1,048,576 retained UTF-8 schema-name bytes. These caps prevent a caller from minting an effectively unbounded retained-metadata envelope before trusted policy runs; they are provider-independent denial-of-service guardrails, not PostgreSQL identifier semantics or source authorization. A request may choose a narrower budget but never a wider one. + +Structural admission is not source authority. `ObservationResourceEnvelope` combines the structurally admitted metadata budget and runtime ceilings into one immutable policy input so trusted local policy can admit only an equal-or-narrower complete resource contract. Request count/byte validation occurs before registry or database access and deliberately does not reuse PostgreSQL's build-time identifier-length default as a security constant. + +A well-formed key, caller-selected schema list, structurally valid metadata budget, and positive runtime envelope are not authority. `ObservationRequest::authorize` resolves the key through the caller's `SourceConnectionRegistry`, requires a nonblank opaque immutable connection-policy binding for that exact mapping, asks the same registry to authorize the exact schema scope against the resulting `ResolvedSourceConnection`, then asks it to admit the complete `ObservationResourceEnvelope` against that same binding. Schema and resource policy methods default to fail closed. A key-only registry therefore cannot silently turn caller-selected schemas or timeout/row/byte/concurrency/schema-metadata ceilings into application grants. Successful authorization produces one non-`Clone` `AuthorizedObservationRequest`; `SourceObservationPort::observe` consumes that envelope by value. One authorization therefore cannot be replayed to multiply the policy-admitted row, byte, concurrency, deadline, or source-access budget. Retry after cancellation or failure requires a fresh `ObservationRequest::authorize` call. Raw DSNs, URLs, shell-style connection parameters, one-word/generic keys, malformed registry identifiers, over-cap structural budgets, over-budget allowlists, blank schema names, exact duplicates and raw credentials do not cross the canonical execution seam. + +`ResolvedSourceConnection` carries only the opaque source key and opaque connection-policy binding. The binding is provider-independent provenance, not connection material. A concrete adapter ACL may resolve credentials only for that exact key-and-binding pair. If a registry key is retargeted from policy/source revision A to B after authorization, an A capability must fail before source access rather than silently inherit B. Exact schema identifiers retain source spelling throughout the policy decision; case or Unicode normalization must not broaden access. Resource admission is likewise bound to the same source-policy revision rather than to a mutable key or caller-selected defaults. + +Caller cancellation and source-disappearance/resource-limit outcomes are part of the typed port seam. Request admission and source/schema/resource registry authorization remain deterministic pre-adapter steps; live adapter execution is awaitable and returns a `Send` future without making an async runtime part of the port contract. The end-to-end operation budget starts before source lookup, policy-binding resolution, schema authorization and resource-envelope authorization, then continues through the single authorized connection/catalog execution. Runtime integration must account for pre-adapter elapsed time rather than restarting the deadline at `observe`, and must re-authorize rather than replay a consumed envelope for a retry. Concrete PostgreSQL drivers, credentials, catalog SQL and scheduling remain adapter responsibilities outside the domain and observation-fact crates. ADR 0004 remains Proposed until a concrete adapter and conformance evidence prove these invariants. + +### PostgresSchemaSnapshot + +Immutable Source Observation aggregate for one bounded relational metadata capture. It owns source-connection reference, the opaque connection-policy binding authorized for that observation, snapshot digest identity, extractor revision, observation time, and exact qualified table observations. The public constructor accepts the complete `AuthorizedObservationRequest`, not a source-only capability, and rejects every locally observed table whose exact schema identifier is absent from the request allowlist before the owner-computed digest or any evidence receipt can exist. Exact matching is case-sensitive and normalization-free. Foreign-key target schema names remain relationship evidence and do not imply that the referenced schema itself was locally observed. Duplicate table coordinates also fail closed. A concrete adapter may construct this aggregate only after a complete bounded capture; cancellation, stale binding, source disappearance, authorization-scope mismatch, or resource exhaustion must not produce a partial snapshot. + +The source-content digest deliberately excludes source identity and policy revision, which remain separate provenance coordinates. `SourceObservationReceipt` therefore carries the stable source key and the exact opaque connection-policy binding alongside the source-content digest, extractor revision, observation time, and verified location. This keeps content identity deterministic without losing which immutable authorization mapping produced the evidence. + +### TableObservation / ColumnObservation + +Immutable Source Observation value objects. Table observations keep exact schema/table identity. Column observations keep exact source name, one-based ordinal, source type, nullability, and optional source comment. Duplicate names or ordinals within a table fail closed, and read APIs return deterministic source order. + +### PrimaryKeyObservation / UniqueConstraintObservation / ForeignKeyObservation / CheckConstraintObservation + +Unique constraints retain null-comparison evidence as unknown, observed distinct, or observed not-distinct. The existing constructor leaves this evidence unknown; observing it produces a new value without changing the original. The Source Observation aggregate binds all three states into v2 snapshot content identity and derived receipts. This is source fact preservation, not a rule for promoting a relational key to semantic authority. + +Immutable Source Observation value objects for deterministic constraint evidence. Composite key order is preserved exactly. Foreign keys retain ordered local and referenced coordinates, including cross-schema targets. When the source adapter observes foreign-key reference behavior, `ForeignKeyReferenceBehavior` preserves exact `ON UPDATE` and `ON DELETE` actions, any PostgreSQL column subset targeted by `ON DELETE SET NULL (...)` or `SET DEFAULT`, match type, and deferrability/initial timing; when it observes PostgreSQL 18 constraint state, `ForeignKeyObservation` also preserves exact `convalidated` and `conenforced` booleans. Either metadata family remains explicitly absent when not observed rather than deriving PostgreSQL defaults. + +`CheckConstraintObservation` retains the reconstructed PostgreSQL definition together with validation, enforcement, and `NO INHERIT` status. PostgreSQL stores a CHECK expression internally and recommends `pg_get_constraintdef()` for reconstruction, so ConceptWeave preserves that adapter-supplied definition as source evidence rather than parsing it into guessed ordered column coordinates. Constraint names remain unique within a table observation, while explicit PK/unique/FK coordinate lists must bind to observed local columns.

The raw `ObservationRequest` accepts only an opaque source registry key of at most 128 bytes in lowercase multiword `snake_case`; syntax alone is not source authority. Its exact schema allowlist is selection metadata until policy approves it: callers may not turn a recognized source key into authority for arbitrary schemas. `ObservationRequest::authorize` first resolves the exact key through the caller's local `SourceConnectionRegistry` and requires that registry to issue a nonblank opaque immutable connection-policy binding for the current mapping. It then requires the same policy boundary to authorize the exact sorted schema scope against that `ResolvedSourceConnection`, not against the mutable key alone. Binding resolution and schema authorization default to fail closed. + +Before any trusted source policy executes, `ObservationRequestBudget` enforces ConceptWeave's provider-independent structural admission caps: no request may retain more than 4,096 exact schema identifiers or 1,048,576 total UTF-8 bytes across those identifiers. Requests above either cap fail with typed `SchemaCountLimitTooLarge` or `SchemaByteLimitTooLarge`; requests exactly at the cap and ordinary narrower budgets remain constructible. These values are product-level denial-of-service guardrails for authorization metadata, not PostgreSQL `NAMEDATALEN`, source-specific authorization, or runtime query limits. + +Positive request limits are also not authority. `ObservationRequestBudget` and `ObservationLimits` describe the caller-requested provider-independent resource envelope within the canonical structural cap: maximum schema count and total retained UTF-8 schema bytes, end-to-end operation timeout, per-statement timeout, row count, retained bytes, and concurrent catalog queries. `ObservationResourceEnvelope` combines those values so the same trusted local registry policy can admit or reject the complete envelope against the same immutable `ResolvedSourceConnection`. `SourceConnectionRegistry::authorizes_resource_envelope` defaults to deny. A source+schema decision therefore cannot silently convert caller-selected ceilings into effective policy. Wider-than-policy requests fail with `UnauthorizedResourceEnvelope` before adapter/source/snapshot side effects; equal or narrower requests proceed only when the local policy explicitly admits them. Source policy can narrow the canonical structural cap but never widen it. + +The connection-policy binding is provider-independent provenance. It must not contain a DSN, credential, token, provider connection object, or wall-clock timestamp. A concrete adapter ACL may resolve least-privilege credentials only for the exact authorized key-and-binding pair. If the registry remaps key K from revision A to revision B after authorization, a capability issued for A must fail before credential/source access rather than silently retarget to B. Exact schema authorization and resource-envelope admission must also have been evaluated against A. This is the port-level defense against mutable-key TOCTOU; the concrete adapter remains responsible for proving the corresponding ACL behavior against real credential/source resolution. + +Registry authorization is a synchronous local policy boundary, not remote credential resolution. The operation's monotonic budget starts before key lookup, policy-binding resolution, schema authorization and resource-envelope admission; an exhausted authorization returns `ObservationRequestError::OperationTimeout`, and the authorized envelope privately retains the monotonic start coordinate. The only timing capability exposed to adapter code is `remaining_operation_budget() -> Option`; no wall-clock timestamp or runtime-specific type crosses the port contract. The registry implementation itself must remain locally bounded because a synchronous trait cannot pre-empt arbitrary remote I/O; remote credential/network work belongs after authorization in the adapter. + +`AuthorizedObservationRequest` is a single-use operation capability, not a reusable session token. It is intentionally non-`Clone`, and `SourceObservationPort::observe` consumes it by value. This preserves the meaning of the policy-admitted row, byte, concurrency and operation budgets: one successful registry authorization can start at most one source observation execution. A cancelled, failed, or completed observation cannot reuse the consumed authorization; retry requires constructing or retaining a raw `ObservationRequest` and obtaining a fresh authorization decision against the current source-policy binding. + +`SourceObservationPort::observe` is an awaitable, `Send` execution seam so an asynchronous source driver can be awaited without a hidden blocking bridge or a runtime dependency in the port crate. Registry implementations at this boundary must remain bounded local authorization lookups; remote credential/network work belongs after authorization in the adapter and is capped by the remaining operation budget. + +Request construction first rejects a caller-selected structural budget above ConceptWeave's hard provider-independent caps, then rejects a schema list that exceeds the accepted narrower metadata envelope before registry/database access. Neither check assumes PostgreSQL's build-time identifier-length default. Structural admission is separate from trusted policy admission: callers cannot make large positive values authoritative merely by constructing them. Exact schema policy is case-sensitive and normalization-free; a differently cased or Unicode-normalized identifier is not implicitly granted. The adapter must then use bounded catalog queries, explicit statement/operation timeout, caller cancellation, row/byte/concurrency limits, exact identifier handling, and immutable extractor receipts. Registry lookup/binding/scope/resource authorization, connection, transaction and catalog work share one non-resetting operation budget. Before each potentially blocking adapter stage, the implementation must read the remaining budget and cap driver/server work accordingly rather than reusing the original duration. It must fail closed on an exhausted budget, cancellation, stale binding, partial or ambiguous catalog evidence, and source disappearance, and must not read another product's application tables through hidden coupling. PostgreSQL catalog reconstruction functions are treated as source rendering, not original DDL text. + +Canonical `PostgresSchemaSnapshot::new` remains a second authorization boundary: it accepts the complete `AuthorizedObservationRequest`, retains the exact opaque connection-policy binding as provenance, and rejects every locally observed table whose exact schema name is absent from the already-authorized request scope before digest or receipt issuance. The concrete adapter owns the single-use request while executing and may borrow it for snapshot construction before `observe` returns; the capability itself is still consumed at the public execution seam. This defense-in-depth check does not replace registry scope/resource authorization. Foreign-key target schema names observed from an authorized local table remain relationship evidence and do not themselves grant authority to read the referenced schema. The source-content digest intentionally excludes source key and policy binding; those are separate immutable provenance coordinates. Every public `SourceObservationReceipt` therefore retains the exact binding alongside source id, digest, extractor revision, observation time and verified location. + +The current port repair makes provider-independent pre-policy structural schema-metadata caps, exact source+immutable-policy-binding+schema+resource authorization, a single-use execution capability, remaining budget, stale-binding rejection at the port seam, snapshot-side scope containment, and binding-preserving immutable receipts representable.

The registry resolves the exact source key to an opaque immutable connection-policy binding, authorizes the exact requested schema scope against that same `ResolvedSourceConnection`, then explicitly admits the complete `ObservationResourceEnvelope` against the same binding. Schema/resource policy defaults to deny. The authorized envelope privately retains the operation start coordinate and exposes only the remaining `Duration` to adapter code. + +## Decision + +`ObservationRequestBudget::new` rejects zero values and any caller-requested count above `MAX_STRUCTURAL_SCHEMA_COUNT = 4_096` or retained schema-name bytes above `MAX_STRUCTURAL_SCHEMA_BYTES = 1_048_576`. The typed `SchemaCountLimitTooLarge` and `SchemaByteLimitTooLarge` errors expose only the product-level maximum. The caps are deliberately provider-independent and bound retained authorization metadata before trusted source policy can run; they are not PostgreSQL identifier limits and do not grant source access. + +`ObservationRequest` then validates a bounded opaque source key, exact schema allowlist, the already structurally capped `ObservationRequestBudget`, and `ObservationLimits`. These positive values establish a structurally bounded request but do not confer policy authority. `ObservationResourceEnvelope` combines the caller-requested metadata and runtime ceilings into one provider-independent value object. Trusted source policy may only admit an equal-or-narrower effective envelope. + +`ObservationRequest::authorize` starts the operation's monotonic budget before local registry policy. It first checks the exact key through `SourceConnectionRegistry::contains_source_connection`, then requires `connection_policy_binding` to issue a nonblank opaque immutable revision for that mapping. A known key with no binding returns `MissingConnectionPolicyBinding`; a malformed binding returns `InvalidConnectionPolicyBinding`. + +The same registry receives the resolved key-and-binding capability plus exact sorted `allowed_schema_names` through `authorizes_schema_scope`. The default schema-scope implementation is fail-closed. A source that exists and is bound but whose requested scope is not explicitly authorized returns `ObservationRequestError::UnauthorizedSchemaScope`; the denial does not echo the schema. No case or Unicode normalization may broaden the grant. Implementations granting a scope must compare the supplied binding with the same policy revision that owns that grant. + +Only after the exact schema scope is admitted does the same local policy evaluate `authorizes_resource_envelope(resolved_source, request.resource_envelope())`. The default resource policy is fail-closed. A registry that recognizes a source and schema but does not explicitly admit the requested metadata/runtime ceilings returns `ObservationRequestError::UnauthorizedResourceEnvelope`. Policy may accept an equal or narrower request and must reject a wider-than-policy request. The port does not hard-code PostgreSQL deployment ceilings or accept provider-specific settings in this value object. + +All local registry decisions are part of the same operation budget. `authorize` checks the same monotonic deadline immediately after source lookup, immutable binding lookup, schema policy, and resource policy. If one stage exhausts `operation_timeout_ms`, `OperationTimeout` takes precedence over that stage's returned policy result and no later registry stage is started. This prevents post-deadline policy side effects while preserving zero adapter/source/snapshot side effects for over-budget authorization. Because `SourceConnectionRegistry` is synchronous, a single in-flight registry call cannot be preempted by this contract and must itself remain bounded local work; the caller-requested timeout is not permission to hide remote I/O inside registry policy. + +A successful authorization returns `AuthorizedObservationRequest`, which binds the validated request to `ResolvedSourceConnection { source_connection_key, connection_policy_binding }`, preserves the explicitly authorized schema scope and explicitly admitted resource envelope in the request, and privately carries the monotonic start coordinate. `remaining_operation_budget() -> Option` is the only timing capability exposed to a concrete adapter. `None` means the end-to-end operation budget has expired. The start coordinate itself is not a public field, serialized timestamp, provider object, or credential. + +`SourceObservationPort::observe` accepts only `AuthorizedObservationRequest` and returns a provider-independent `Send` future. Request construction remains deterministic. Authorization is synchronous and local but deadline-aware; it is not described as time-independent. A registry implementation that performs remote I/O would violate this boundary: remote credential/network work belongs inside the concrete adapter and must be capped by the remaining budget. + +A concrete adapter ACL may resolve credentials only for the exact key-and-binding pair carried by the authorization. If the live mapping has advanced from revision A to B, an A capability must be rejected before credential/source access and before snapshot construction. The port-level synthetic adapter fixture models this fail-closed contract; only a later concrete adapter test can prove real credential/source behavior. + +The public `PostgresSchemaSnapshot::new` accepts the complete `AuthorizedObservationRequest`, rather than the narrower `ResolvedSourceConnection`. Before owner-computed digest construction it compares every locally observed table's exact `schema_name` with `request().allowed_schema_names()` and fails closed when a table lies outside that scope. This is defense in depth after registry schema/resource authorization. Matching is exact and case-sensitive; no Unicode/case normalization broadens authorization. A foreign key may retain a referenced schema outside the local read allowlist because that name is relationship metadata observed from an authorized local table, not evidence that ConceptWeave read the referenced table. + +The public immutable snapshot also retains the authorized opaque connection-policy binding. The source-content SHA-256 digest remains based only on complete exact observed metadata; source key and policy binding are separate provenance coordinates. `SourceObservationReceipt` carries the exact binding alongside source id, source-content digest, extractor revision, observation time, and verified location so later evidence cannot collapse two different registry mappings that reused the same source key. + +The concrete adapter must read the remaining budget before potentially blocking connection/transaction/statement/cancellation work and cap each stage according to both the policy-admitted `ObservationLimits` and that remainder. It must not restart `operation_timeout_ms` at `observe`. A caller-side outer timeout may still bound waiting, but it is not a substitute for passing the remaining budget into driver/server limits. + +This ADR remains **Proposed**. The port can now represent canonically capped pre-policy schema-selection metadata, source-key plus immutable-policy-binding authorization, exact schema-scope authorization, trusted complete resource-envelope admission, stale-binding rejection at the port seam, non-resetting budget with post-stage cutoff, canonical snapshot scope binding, and binding-preserving public provenance. No production PostgreSQL adapter or exact-head runtime conformance has yet proved the full decision. + +## UNIQUE null-comparison refinement (2026-09-06; Proposed) + +In the context of preserving immutable relational evidence for later semantic proposals, facing a demonstrated identity collision between otherwise equal UNIQUE constraints with different null comparison, we decided for an optional observed boolean and explicitly versioned v2 content framing and against inferring an unobserved default, retaining v1 framing for changed bytes, or adding a general index model, to achieve distinguishable and reproducible source evidence, accepting new snapshot digests even for observations with no unique constraints and a future explicit compatibility boundary for historical v1 evidence. + +The Source Observation owner remains responsible for the value and digest. The PostgreSQL ACL later reads the supporting index through pg_constraint.conindid and preserves pg_index.indnullsnotdistinct. No database query, provider type, dependency, general-index surface, unique deferrability or period semantics is introduced here. Missing evidence is None; observed false and true are distinct. The existing optional-boolean encoder is reused. Old receipts remain historical and immutable; this change does not provide wire-version negotiation, rewrite old receipts, establish a business key, or approve semantic publication. + +Alternatives rejected: an ordinary boolean defaults unknown evidence to a database assumption; an adapter-only flag leaves canonical identity incomplete; comments or parsing reconstructed SQL do not bind the typed fact; adding bytes under the old framing domain obscures a format change. A general index abstraction is unnecessary for the reviewed collision and remains outside this handoff. + +The schema-byte admission check now compares each name against the remaining admitted byte ceiling before adding its length. The accumulator starts at zero and stays at or below the already validated product cap, so subtraction and the following addition remain bounded. This replaces two guards, including an unreachable allocation-sized overflow branch, without changing the cap, error, exact identifiers or authorization order. Tests cover cumulative ASCII and UTF-8 boundaries. Standard async test implementations and std::task::Waker::noop replace hand-written wrappers; the production Send future contract is unchanged. + +Evidence: the UNIQUE null-comparison review on PR #6; functional collision RED at bab6984; collision plus framing RED at 8b5b738; focused six-test GREEN at 6c23924. Full validation exposed unrelated pre-existing documentation, formatting, Clippy and coverage failures; ordinary successor commits retain that evidence and repair it. Runtime e3ac294 passes 132 tests including two doctests, strict fmt/Clippy/rustdoc, release build, and the unchanged coverage gate (228/228 functions, 2026/2026 normalized regions, 194/194 normalized branches). Raw LLVM remains 1807/1825 lines, 2192/2206 regions and 188/194 branches: this is not a claim of 100% raw coverage. See ../doctoring/source-observation-unique-null-semantics.md for exact hashes, commands, standards and remaining gates. + +Positive consequence: unique null comparison now participates in value, snapshot and receipt identity without silently upgrading unknown evidence. Negative consequence: framing v2 is not hash-compatible with v1 and needs explicit consumer admission before any serialized release. Open risks: no concrete PostgreSQL adapter conformance, protected Product evidence, current-head independent approval, or immutable release is established by local tests.

This report records local contract verification, not a protected merge, live database observation or semantic approval. + +## Problem and source evidence + +A data architect comparing two revisions of the same unique constraint must be able to detect a change in which rows it admits. PostgreSQL 18 documents that `pg_index.indnullsnotdistinct=false` treats nulls as distinct, whereas `true` treats them as equal for uniqueness. Its constraint catalog identifies the supporting index with `conindid` (PostgreSQL Global Development Group, 2026a, 2026b, 2026c). These facts support retaining the observed boolean; they do not establish a business key, require a particular Rust type, or authorize semantic publication. + +The predecessor retained only constraint name and ordered columns, so equal coordinates could conceal different source behavior. The repair preserves three states: unknown, observed distinct, and observed not-distinct. The existing constructor keeps unknown evidence. A consuming builder records an observed boolean without mutating the original value. The canonical digest reuses the existing optional-boolean encoder and moves its framing domain to v2. No driver, database query, general index abstraction or new dependency is added. + +The Source Observation owner explicitly handed this bounded repair to an isolated worktree starting at `e3c415600300b6c2d5b852c457ea6ab2e5222e08`, retaining base `fcf36c8a99f015b963c9f812787df127ac2e2f9e`.

Restore the omitted explanation without changing Client runtime or weakening that test. -Fresh owner RCA invalidated that causal hypothesis. The same authenticated exact-range request returned HTTP 200 for a repository whose dependency graph was initialized and HTTP 403 for affected repositories whose graph was not initialized. Enabling Dependabot vulnerability alerts initialized the dependency graph in ConceptWeave and pingora-gateway, after which the exact compare endpoint returned HTTP 200. Therefore `.github#1873` was correctly closed without merge: retries would extend queue occupancy but would not establish repository capability. +`ObservationRequestBudget` enforces a canonical provider-independent hard ceiling before trusted source policy runs: at most 4,096 exact schema identifiers and at most 1,048,576 retained UTF-8 bytes across those identifiers. Over-cap caller requests return typed `SchemaCountLimitTooLarge` or `SchemaByteLimitTooLarge`; exact-cap and ordinary narrower budgets remain constructible. These values bound ConceptWeave's retained authorization metadata against pre-policy resource abuse and do not encode PostgreSQL identifier semantics or grant source authority. -Acceptance remains stricter than the RCA. HTTP 200 availability alone is not GREEN. A fresh exact ConceptWeave consumer run must reach and complete the pinned Dependency Review action; 403, transport failure, skipped substitution or a sibling scanner cannot satisfy the hard gate. +`ObservationRequest` accepts only bounded opaque source keys, explicit exact-schema allowlists, a structurally capped caller-requested authorization-metadata budget, and positive operation/statement/row/byte/concurrency limits. Structural admission and request-local bounds are not source policy. `ObservationResourceEnvelope` combines the metadata and runtime ceilings into one provider-independent policy input, and trusted source policy may only admit an equal-or-narrower effective envelope. -## Central control-plane evidence +The local `SourceConnectionRegistry` must issue a bounded opaque immutable connection-policy binding and authorize both the exact schema scope and complete resource envelope against the resulting `ResolvedSourceConnection`. Schema and resource policy default to fail closed. A known key without a binding cannot execute; connection material such as a PostgreSQL DSN is rejected as an invalid binding; source+schema authorization without a trusted resource decision returns `UnauthorizedResourceEnvelope`. A wider-than-policy resource request must fail before adapter/source/snapshot side effects, while equal or narrower requests proceed only through an explicit policy grant. -Protected central source is `.github/main@b5efbc2762e472e4a380b0503b1f050f76fbb008` at this snapshot. This is evidence only, not a mutable ConceptWeave dependency. +`AuthorizedObservationRequest` carries only the validated and policy-admitted request, source key, opaque policy binding, and private monotonic operation-start coordinate. It is intentionally non-`Clone`, and `SourceObservationPort::observe` consumes it by value. One successful registry authorization therefore crosses the canonical execution seam at most once; cancellation, failure, or success consumes the capability and retry must obtain a fresh authorization against current policy. This closes replay amplification of the admitted row/byte/concurrency/deadline/source-access budget without introducing provider/runtime state. -- The current central source includes queue/admission and changed-scope/review-runtime repairs already integrated through ordinary protected history. -- `.github#1873@41935494aa234eb458f1cc08f006daaa278b9760` is closed/unmerged because repository dependency-graph initialization, not its retry/sleep source delta, was the verified root cause of the observed public-repository 403. -- #35 remains an exact consumer canary for current runner admission and Dependency Review behavior. Its central workflows are queued, so no protected recovery or dependency-review success is inferred from repository settings alone. +Source lookup, binding, schema policy and resource policy all consume the same operation budget before adapter execution. The adapter receives only `remaining_operation_budget()` rather than a reset timeout. A later adapter ACL may resolve credentials only for the exact key-and-binding pair. A capability authorized for revision A must not silently retarget to revision B after the registry changes; the port fixture requires stale-binding failure before source and snapshot side effects and has an unchanged-binding positive control. + +`PostgresSchemaSnapshot::new` requires the complete authorized envelope, rejects locally observed table schemas outside the exact authorized allowlist before digest/receipt construction, and retains the authorized policy binding as immutable provenance. The adapter may borrow the request while it owns the single-use capability inside one `observe` future. Source-content digest identity remains separate from source key and policy revision. Public `SourceObservationReceipt` retains source id, exact policy binding, digest, extractor revision, observation time and verified location. Foreign-key target schemas remain relationship evidence and do not grant read authority for those schemas. + +Replay/resource admission has executable fixtures for five security layers: canonical structural over-cap rejection before registry access; default denial when source+schema authority has no resource policy; wider-than-policy source-envelope rejection before adapter/source/snapshot side effects; exact-ceiling/narrower positive controls; and compile-contract/source fixtures requiring a fresh authorization per execution. The current local handoff can execute these fixtures. Earlier no-toolchain statements remain historical limitations of the predecessor writer, not a current local limitation; hosted acceptance is still unverified. + +### UNIQUE identity repair and measured baseline + +The reviewed UNIQUE collision is reproduced before repair and closed in local contract tests: otherwise equal constraints with unknown, observed distinct and observed not-distinct null comparison produce pairwise different value, snapshot and receipt identities. The existing optional encoder is reused under `conceptweave.postgres_schema_snapshot.v2`; old v1 receipts remain historical and immutable. No live catalog adapter, semantic decision or source write is introduced. + +Runtime `e3ac294b976d35f113fe9b920060f62c4a28f57f` passes 132 tests across 42 suites, including two doctests, plus strict fmt/Clippy/rustdoc, release build, Product CI contract and actionlint. The unchanged coverage gate improves from 2012/2017 normalized regions and 191/196 normalized branches at the first null repair to 2026/2026 and 194/194 after actual missing paths and the byte guard are repaired; functions remain 228/228. The branch denominator decreases because the redundant overflow guard is removed. Raw LLVM remains 1807/1825 lines, 2192/2206 regions and 188/194 branches, not 100%. + +Baseline Client documentation failure, missing-API RED, functional digest collision, framing RED, strict Clippy failure and intermediate coverage failures are retained in ordinary commits/logs. [The doctoring report](doctoring/source-observation-unique-null-semantics.md) records exact hashes, commands, PostgreSQL evidence, alternative rejection and remaining gates. ADR 0004 and ADR 0006 remain Proposed. Final documentation-head tests and current remote review/check coordinates must be re-fetched after publishing the successor; local pass does not transfer predecessor review approval or qualify a protected merge. + +## Central owner evidence relevant to #35 + +Protected central source is `.github/main@fb2ae81dbeaacb0c630e51e9d772c6919fa220cf` at this snapshot. `.github#1929` remains open and the issue still records the core mismatch between app-token `opencode-agent[bot]` dispatch and an allowlist historically holding `github-actions[bot]`; later owner evidence also identified review-fix user-token dispatch. ConceptWeave does not widen that authorization boundary or replay stale failed handles. + +Owner acceptance remains machine-principal reconciliation followed by fresh current-central-head OpenCode/CodeQL/review-fix canaries where `actor == sender == exact listed machine identity`, exact repository/PR/base/head/wake metadata binds correctly, substantive work begins, and an otherwise equivalent user-account dispatch remains rejected. + +#35 also remains blocked by the separate Noema contradicted-capability review and current-owner Strix evidence. These are owner-path blockers for #35 only; they do not justify speculative Source Observation provider fallbacks or weakening ConceptWeave gates. ## P0 product gaps -1. **Concrete Source Observation adapter** — maintained Rust PostgreSQL driver behind `conceptweave-source-port`; adapter-local registry/credential resolution; explicit read-only session/transaction; exact schema allowlist; total operation and statement deadlines; cancellation plus row/byte/concurrency budgets; complete immutable snapshot or fail closed; source-disappearance handling; deterministic replay against a frozen anonymized GRC-shaped fixture. -2. **Observed PostgreSQL surface completion** — domains/enums/indexes/comments, quoted identifiers and cross-schema collisions as generic observed evidence without importing source-system business truth. -3. **Ontology discovery** — deterministic term/concept/taxonomy/non-taxonomic-relation candidate generation with exact source receipts and abstention for unsupported semantics. -4. **Semantic-layer discovery** — dimensions, measures, grain, units, relationships and physical mappings with deterministic calculation contracts; do not infer business authority from relational structure alone. -5. **LLM Proposal** — every production model call through a released `contextual-orchestrator`; outputs remain proposed/inferred and preserve source/model/prompt/provenance evidence. -6. **Alignment / matching** — retrieval/pruning/structural evidence first, bounded optional LLM assistance, OAEI-style evaluation, deterministic reproducibility and steward-visible decisions. -7. **Validation engine** — RDF/OWL/SKOS/SHACL and semantic-layer validation, consistency/conflict/duplicate detection, bounded reasoning and explicit unsupported-feature failure. -8. **Governance persistence** — PostgreSQL 3NF candidates/evidence/validation/review/release/supersession receipts, transactional outbox and temporal history only where domain semantics require it. -9. **Review workflow** — Keyverse identity context, tenant/role/purpose authorization, steward decisions, maker-checker where required, stale-decision protection and immutable publication receipt. -10. **Publication adapters** — versioned OWL/RDFS/SKOS/SHACL/JSON-LD plus explicitly version-bound Apache Ossie export; draft/incubating formats cannot be presented as final standards. -11. **Client completion** — language-neutral release/supersession contract, provenance/signature verification, relation/mapping/dimension/measure resolution, compatibility/deprecation, match/explain/query-plan contracts while downstream products retain physical authorization/execution. -12. **CWL integration** — only released/versioned `semantic_release`/contract/ACL seams to `semantic-data-portal`, `context-graph-contracts`, GRC, EA and other consumers; no source copying, cross-service SQL or mutable supplier heads. -13. **Evaluation / multilingual** — reviewed golden fixtures, ontology-learning/matching metrics, source-evidence binding, abstention, reproducibility, KO/EN/JA/ZH/VI/ES/DE/FR labels, CJK/font/text-expansion checks where UI or published labels are material. -14. **Observability / recovery / release** — structured telemetry, security evidence, backup/restore, package/SBOM/provenance/signing, reproducible build and rollback proof before immutable release. +1. **Exact-head Source Observation verification** — publish and reverify the ordinary successor, obtain current-head independent review and hosted Product/security/dependency evidence after protected prerequisites integrate, and account for remaining raw LLVM coverage differences.
