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, 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. These contracts preserve source metadata only and do not infer join semantics, CHECK dependencies, or business meaning.

Mitigation: adapter conformance tests must force timeout, row, byte, concurrency, cancellation, and disappearance failures and verify no snapshot is returned. +- **Credential-shaped caller input:** a caller could otherwise place a DSN or connection parameter string in `source_connection_key` even though the field was documented as non-credential. Mitigation: the port accepts only bounded multiword `snake_case` registry keys; credential lookup remains exclusively inside the adapter ACL. - **Blocking execution:** a blocking driver could stall an asynchronous product executor. Mitigation: adapter design must isolate blocking work or use an async Rust driver; no blocking database call may run on an async web executor thread. - **Authorization drift:** a broad or normalized schema selector could observe unintended metadata. Mitigation: exact non-empty allowlists are part of the port and must be applied before catalog results become observations. - **Partial evidence:** a source can disappear mid-capture.

For foreign keys, observed `ON UPDATE`/`ON DELETE` actions, match type, deferrability/initial timing, and PostgreSQL validation/enforcement state are retained as typed source evidence; each metadata family remains explicitly absent if the adapter did not observe it rather than inventing defaults. For CHECK constraints, preserve the PostgreSQL-reconstructed definition together with validation, enforcement, and `NO INHERIT` status; do not infer ordered expression-column coordinates from SQL text. It must not normalize identifiers in ways that erase PostgreSQL quoting or schema boundaries. ### FR-2 Candidate discovery From 9adc42de677016222b20e73c5fbb5966ab0247f2 Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Wed, 2 Sep 2026 21:36:54 +0900 Subject: [PATCH 055/238] docs(trd): bind source registry ACL contract --- docs/TRD.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/TRD.md b/docs/TRD.md index 792e3a6f..35976e8f 100644 --- a/docs/TRD.md +++ b/docs/TRD.md @@ -35,7 +35,7 @@ Every observed source will eventually carry at least: The active PostgreSQL slice already preserves exact schema/table/column identifiers, deterministic column ordinals, source type/nullability/comments, composite PK/unique/FK coordinates, exact optional FK update/delete/match/deferrability behavior, CHECK reconstructed definitions, CHECK validation/enforcement/`NO INHERIT` state, canonical lowercase `sha256:<64 hex>` snapshot identity, extractor revision, observation time, and verified table/column/constraint receipts.

ConceptWeave therefore accepts only an explicit UTC form with uppercase `T`/`Z`, a four-digit Gregorian date, complete hour/minute/second fields, and optional decimal fractional seconds. Numeric or local offsets are rejected rather than silently normalized because normalization would replace the adapter-supplied evidence string with a derived representation. + +The validator checks Gregorian month/day bounds and the RFC 3339 clock range. A syntactic `:60` second is accepted only at `23:59`; that preserves the RFC 3339 leap-second syntax boundary without claiming that ConceptWeave has independently verified an IERS leap-second announcement for the supplied date. Historical/operational leap-second authority remains source-clock evidence outside this value-object validator. + +PostgreSQL accepts a deliberately broad family of date/time inputs and converts `timestamp with time zone` values to UTC internally, while not retaining the originally supplied zone.

It rejects raw DSNs/URLs/key-value connection material, one-word/generic keys, malformed registry identifiers, and blank or duplicate schema identifiers, and sorts the allowlist only for deterministic request identity. `SourceConnectionRegistry` resolves the exact key and issues `ResolvedSourceConnection`; `PostgresSchemaSnapshot` accepts only that opaque capability. `ObservationCancellation` carries caller cancellation. `SourceObservationPort` defines the adapter seam. `SourceObservationFailure` distinguishes cancellation, source disappearance, timeout, invalid captured metadata, and row/byte/concurrency-limit exhaustion. +`PostgresSchemaSnapshot` computes its own `sha256:` identity after exact table ordering is canonicalized. The digest input uses a versioned domain separator (`conceptweave.postgres_schema_snapshot.v1`) and an explicit length-prefixed binary framing. Strings are hashed as their exact UTF-8 bytes without Unicode, case, or PostgreSQL-quoting normalization. Collection lengths and string lengths are unsigned 64-bit big-endian values; column ordinals are unsigned 32-bit big-endian values; booleans, options, constraint variants, referential actions, match types, and deferrability states use explicit stable tags. Table order, column order, and constraint order are deterministic; ordered composite-key and foreign-key coordinates remain order-significant because PostgreSQL reports those positions as source evidence. + +The v1 content envelope includes exact table identifiers, column names/ordinals/types/nullability/comments, and every owned PK/unique/FK/CHECK field, including optional FK reference behavior, targeted delete columns, validation/enforcement state, CHECK definition, and `NO INHERIT`. It excludes `source_connection_key`, `extractor_revision`, and `observed_at_utc`; those remain separate receipt provenance. Changing any observed source-content field changes the digest, while changing only input collection order or those provenance coordinates does not. Receipts expose only the snapshot's owner-computed digest. + +SHA-256 is the current digest primitive under NIST FIPS 180-4.

The port therefore needs an explicit provider-independent request-metadata budget without pretending PostgreSQL's build-time identifier-length default is a ConceptWeave security constant. +Three independent admission/integrity gaps are material to this boundary. First, a syntactically valid caller-supplied digest is not proof that the digest was computed from the observed metadata. Second, captured catalog row/byte limits do not bound the caller-owned exact-schema allowlist retained before source access. Third, a registry capability is not an authorization boundary if the primary adapter method can still accept a raw request and succeed without registry resolution. ## Constraints - Source systems are read-only inputs; ConceptWeave does not own their business truth. -- Only an opaque source registry key may cross the port: at most 128 bytes, lowercase multiword `snake_case`. An authorized registry lookup must issue the capability accepted by immutable snapshots; syntax alone is not provenance authority. Passwords, tokens, DSNs, URLs, shell-style connection parameters, and provider-specific connection objects may not cross this boundary. -- Every request needs an explicit non-empty exact-schema allowlist, a positive caller-selected allowlist count/total-UTF-8-byte budget, and positive operation/statement-timeout, row, byte, and concurrency bounds. -- Request authorization metadata must be rejected before registry or database access when it exceeds its explicit budget. -- Caller cancellation and source disappearance must fail closed rather than return a fabricated or partial success. -- Exact source identifiers keep original case/text; canonicalization may order an allowlist but must not normalize identifier meaning. -- Snapshot content identity must be derived from the complete observed metadata owned by this bounded context. Caller-supplied digest syntax is not proof of content identity. -- Source registry identity, extractor revision, and observation time are explicit provenance coordinates. They are not source-content bytes and must not change the content digest for an otherwise identical observation. -- Digest framing must be versioned and domain-separated so later metadata-model changes cannot silently reinterpret an existing digest. -- The port must remain provider-independent and free of PostgreSQL driver, credential, semantic-inference, publication, or LLM responsibilities. -- The concrete PostgreSQL adapter must remain outside `conceptweave-domain`, `conceptweave-observation`, and the port contract. +- Only a bounded opaque registry key may appear in request/domain objects: at most 128 bytes, lowercase multiword `snake_case`. Passwords, tokens, DSNs, URLs, shell-style connection parameters and provider connection objects do not cross this boundary. +- Key syntax is admission hygiene, not authorization. An authorized `SourceConnectionRegistry` must issue the opaque capability before a request can reach `SourceObservationPort` execution. +- Every request has a non-empty exact-schema allowlist, positive caller-selected schema-count/total-UTF-8-byte admission budget, and positive operation/statement-timeout, row, byte and concurrency bounds. +- Request authorization metadata is rejected before registry or database access when it exceeds policy. +- Exact source identifiers preserve original source text.

Credential resolution stays inside its Anti-Corruption Layer. ## Options considered -### Put limits and source execution into `conceptweave-observation` +### Put execution policy into `conceptweave-observation` + +Rejected. That crate owns immutable observation facts. Driver execution policy would collapse fact identity and live-source concerns into one aggregate boundary. + +### Let every adapter define its own authorization, timeout and failure vocabulary -Rejected. That crate owns immutable observation facts. Mixing driver execution policy into the fact model would collapse the Source Observation aggregate boundary and make deterministic replay depend on live-source concerns. +Rejected. Resource safety and authorization would become adapter convention rather than a reusable product contract, weakening conformance and allowing silent divergence. -### Let each PostgreSQL adapter define its own timeout/allowlist/error vocabulary +### Treat a well-formed registry key as sufficient source authority -Rejected. This would make resource safety and cancellation non-portable, weaken conformance tests, and allow downstream adapters to silently diverge on what counts as bounded observation. +Rejected. Syntax cannot establish whether the caller is allowed to observe the named source. The earlier `SourceObservationPort::observe(&ObservationRequest, ...)` shape demonstrated the problem: an implementation could succeed without ever consulting `SourceConnectionRegistry` while satisfying the trait. -### Hard-code PostgreSQL's current identifier-length default as the allowlist resource bound +### Hard-code PostgreSQL's identifier-length default as request-memory policy -Rejected. Exact identifiers are source evidence, PostgreSQL builds can change the identifier-length constant, and a provider implementation detail is not the same concern as ConceptWeave request-memory admission. The caller must choose a positive provider-independent schema-count and total UTF-8 byte budget appropriate to its product/tenant policy. +Rejected. PostgreSQL build defaults are provider implementation details, not ConceptWeave authorization-memory policy. Exact identifiers are source evidence and may not be truncated to fit a convenience constant. -### Pass a raw connection string plus arbitrary SQL callback through a generic utility layer +### Pass a raw connection string or arbitrary SQL callback -Rejected. Raw credentials would cross the boundary, arbitrary SQL would make read-only enforcement unauditable, and a generic utility bucket would erase the Source Observation ubiquitous language. +Rejected. It would cross credential boundaries, make read-only enforcement unauditable and erase Source Observation ubiquitous language. ### Trust an adapter-supplied SHA-256 string as snapshot identity -Rejected. Canonical `sha256:<64 lowercase hex>` syntax proves only representation shape. It does not prove that the digest was computed from the observed tables, columns, constraints, or their exact source metadata. +Rejected. Canonical `sha256:<64 lowercase hex>` syntax proves representation shape only, not binding to tables, columns or constraints. -### Canonicalize the internal observation model through a general JSON or CBOR wire format +### Canonicalize through a general JSON or CBOR wire format now -Deferred. RFC 8949 deterministic CBOR is a sound standard when a protocol needs deterministic encoded bytes, and a future cross-language Source Observation artifact may adopt it. The current digest is an internal aggregate identity, however, and making a general serialization format canonical now would introduce a wire-format commitment that the current Rust-only fact model does not otherwise require. JSON canonicalization has the same premature wire-contract problem for this boundary. +Deferred. RFC 8949 deterministic CBOR is a suitable benchmark for a future cross-language artifact, but the current digest is an internal Rust aggregate identity. Introducing a general wire format now would create a serialization commitment the current boundary does not need. -### Define a small provider-independent Source Observation port and an owner-computed content digest +### Provider-independent request + authorized execution envelope + owner-computed digest -Selected. `conceptweave-source-port` owns request budgets, exact schema authorization, bounded opaque source registry keys, caller cancellation, and typed fail-closed outcomes. `conceptweave-observation` owns deterministic observed facts and derives their content identity itself. +Selected. `conceptweave-source-port` owns request admission, authorization capability binding, cancellation and fail-closed execution outcomes. `conceptweave-observation` owns immutable facts and source-content identity. ## Decision -Introduce the Rust workspace crate `conceptweave-source-port` as a Supporting-domain port contract. `ObservationLimits` requires positive operation/statement-timeout, row, byte, and concurrency limits. `ObservationRequestBudget` separately requires a positive maximum schema count and positive maximum total UTF-8 bytes retained across exact schema identifiers. No provider-derived default is embedded in the port; the caller/application policy chooses these values explicitly. `ObservationRequest` requires that budget, an opaque source registry key of at most 128 bytes using lowercase multiword `snake_case`, plus a non-empty exact schema allowlist. It rejects raw DSNs/URLs/key-value connection material, one-word/generic keys, malformed registry identifiers, over-budget allowlists, and blank or duplicate schema identifiers, and sorts the allowlist only for deterministic request identity. Count and byte admission happen before the registry can be resolved or an adapter can receive the request. `SourceConnectionRegistry` resolves the exact key and issues `ResolvedSourceConnection`; `PostgresSchemaSnapshot` accepts only that opaque capability. `ObservationCancellation` carries caller cancellation. `SourceObservationPort` defines the adapter seam. `SourceObservationFailure` distinguishes cancellation, source disappearance, timeout, invalid captured metadata, and row/byte/concurrency-limit exhaustion. +`ObservationLimits` requires positive operation/statement-timeout, row, byte and concurrency limits. `ObservationRequestBudget` separately requires positive maximum schema count and total retained UTF-8 schema bytes. Caller/application policy selects these values explicitly; no provider-derived default is embedded. + +`ObservationRequest` accepts a bounded opaque source registry key plus a non-empty exact schema allowlist. It rejects raw connection material, malformed/generic keys, blank or duplicate schema identifiers and over-budget authorization metadata before registry or database access. It sorts only the allowlist order for deterministic request identity. + +`SourceConnectionRegistry` is the authorization boundary for the opaque key. `ObservationRequest::authorize` consumes a validated request, resolves its exact key through that registry and returns `AuthorizedObservationRequest`, which privately binds the request to the resulting `ResolvedSourceConnection`. `SourceObservationPort::observe` accepts only `AuthorizedObservationRequest`; a raw request or unknown key therefore cannot reach the adapter execution seam through the canonical port API. The authorization envelope contains no credential material. The concrete adapter resolves its already-authorized opaque capability to least-privilege credentials inside its own ACL. + +Registry authorization remains part of the same end-to-end operation policy as connection and catalog work. The concrete application/adapter integration must demonstrate that the configured operation deadline covers authorization, connection and all catalog work rather than treating authorization as an unbounded pre-step. ADR 0004 remains Proposed until that runtime conformance is implemented and verified. -`PostgresSchemaSnapshot` computes its own `sha256:` identity after exact table ordering is canonicalized. The digest input uses a versioned domain separator (`conceptweave.postgres_schema_snapshot.v1`) and an explicit length-prefixed binary framing. Strings are hashed as their exact UTF-8 bytes without Unicode, case, or PostgreSQL-quoting normalization. Collection lengths and string lengths are unsigned 64-bit big-endian values; column ordinals are unsigned 32-bit big-endian values; booleans, options, constraint variants, referential actions, match types, and deferrability states use explicit stable tags. Table order, column order, and constraint order are deterministic; ordered composite-key and foreign-key coordinates remain order-significant because PostgreSQL reports those positions as source evidence. +`PostgresSchemaSnapshot` computes its own `sha256:` identity after exact table ordering is canonicalized.

It excludes `source_connection_key`, `extractor_revision`, and `observed_at_utc`; those remain separate receipt provenance. Changing any observed source-content field changes the digest, while changing only input collection order or those provenance coordinates does not.

Receipts expose only the owner-computed digest plus separate provenance coordinates. -SHA-256 is the current digest primitive under NIST FIPS 180-4. The framing is intentionally ConceptWeave-owned rather than an implicit Rust memory/serde representation, so compiler layout, map iteration, or serializer defaults cannot alter identity. A future framing revision must use a new domain/version and document migration rather than silently changing v1 semantics. +SHA-256 follows NIST FIPS 180-4. A future framing revision must use a new domain/version and migration contract rather than silently reinterpret v1. A future published cross-language observation artifact may adopt deterministic CBOR under RFC 8949; v1 does not claim CBOR compatibility. -This decision does **not** claim that a production PostgreSQL adapter exists. The next owner-side implementation must select a maintained Rust PostgreSQL driver, resolve the registry key to credentials inside the adapter ACL, establish read-only transaction/session behavior, enforce every port limit in execution rather than configuration only, populate the immutable `conceptweave-observation` contracts, and prove cancellation/source-disappearance behavior against a frozen anonymized reference fixture before live-source readiness is claimed. +This decision does **not** claim a production PostgreSQL adapter exists.

Mitigation: adapter conformance tests must force timeout, row, byte, concurrency, cancellation, and disappearance failures and verify no snapshot is returned. -- **Unbounded request authorization metadata:** a caller could otherwise retain an arbitrarily large exact-schema allowlist before the adapter's captured-source byte budget applies. Mitigation: `ObservationRequestBudget` requires explicit positive count and total UTF-8 byte ceilings and rejects over-budget requests before registry/database access; no PostgreSQL identifier-size default is used as a security shortcut. -- **Credential-shaped caller input:** a caller could otherwise place a DSN or connection parameter string in `source_connection_key` even though the field was documented as non-credential. Mitigation: the port accepts only bounded multiword `snake_case` registry keys; credential lookup remains exclusively inside the adapter ACL. -- **Blocking execution:** a blocking driver could stall an asynchronous product executor. Mitigation: adapter design must isolate blocking work or use an async Rust driver; no blocking database call may run on an async web executor thread. -- **Authorization drift:** a broad or normalized schema selector could observe unintended metadata. Mitigation: exact non-empty allowlists plus caller-selected count/byte budgets are part of the port and must be applied before catalog results become observations. -- **Partial evidence:** a source can disappear mid-capture. Mitigation: incomplete captures fail with `SourceUnavailable`; immutable snapshot identity is issued only after a complete bounded capture. -- **Digest framing drift:** adding a new observed field without defining its identity semantics could make two implementations disagree. Mitigation: v1 is domain-separated and explicit; future framing changes require a new version/domain plus regression fixtures rather than an in-place reinterpretation. -- **Unicode or identifier normalization drift:** visually similar identifiers can have different source bytes. Mitigation: v1 hashes exact UTF-8 source text and performs no normalization. -- **Cross-language replay:** an ad hoc serializer would be difficult to reproduce safely. Mitigation: v1 specifies primitive tags, byte order, and length framing explicitly; if a published cross-language artifact is required, standard deterministic CBOR is reconsidered at that contract boundary. +- **Configuration without enforcement:** a concrete adapter can accept budgets but ignore them. Conformance must force timeout, row, byte, concurrency, cancellation and source-disappearance failures and prove no snapshot is returned. +- **Authorization bypass:** an implementation could otherwise use a syntactically valid raw key directly. Canonical adapter execution now requires `AuthorizedObservationRequest`; unknown keys fail before that value exists. +- **Credential-shaped caller input:** request keys are bounded multiword `snake_case`; actual credential lookup remains adapter-local. +- **Authorization deadline gap:** moving authorization ahead of adapter execution can accidentally exclude it from the total deadline. Runtime integration must prove one end-to-end operation budget across authorization, connection and catalog work before ADR acceptance. +- **Unbounded authorization metadata:** explicit schema count/byte ceilings apply before registry/database access. +- **Blocking execution:** blocking DB work may not run on an async web executor thread; select an async Rust driver or isolate blocking work. +- **Authorization drift:** exact schema allowlists remain exact, non-empty and unnormalized. +- **Partial evidence:** incomplete capture fails; immutable snapshot identity is issued only after complete construction. +- **Digest framing drift:** new observed identity fields require a new framing version/domain and regression fixtures. +- **Unicode/identifier normalization drift:** v1 hashes exact UTF-8 source bytes. +- **Cross-language replay:** if published replay becomes a requirement, adopt a standard deterministic representation rather than implicit Rust/serde layout. ## Effects -The Source Observation Context Map now has three explicit layers: caller/application -> `conceptweave-source-port` -> concrete source adapter -> `conceptweave-observation` immutable facts. Semantic Discovery consumes completed observation facts and receipts only; it never receives a live connection handle. Governance & Publication remains downstream and does not gain source execution authority. The caller can reference an approved source connection only through a registry key; adapter-local credential resolution remains an Anti-Corruption Layer concern. +The Context Map is now caller/application → request admission + registry authorization (`conceptweave-source-port`) → authorized execution envelope → concrete source adapter → immutable `conceptweave-observation` facts. Semantic Discovery consumes completed observations/receipts only and never sees a live connection handle. Governance & Publication gains no source-execution authority. -The port no longer relies on an implicit or provider-derived request-size convention. The caller chooses the authorization-metadata budget as policy, while the port validates that policy is positive and enforces it before source resolution. Exact schema bytes remain source identifiers rather than normalized labels. +The request-memory budget and source authorization are separate invariants. A key can be syntactically valid yet unauthorized; an allowlist can be authorized in principle yet rejected because its retained metadata exceeds policy. Neither condition is silently converted into source access. -The immutable observation aggregate no longer treats a caller-provided digest as evidence. Content identity is computed inside its canonical owner after deterministic ordering; provenance remains separately inspectable through source registry, extractor, timestamp, and evidence-location coordinates. +Snapshot identity is owner-computed. Provenance remains separately inspectable through source registry, extractor, timestamp and evidence-location coordinates. ## Concrete scenes -- **Data architect:** selects an approved source registry key, exact schemas, and an explicit schema-count/total-byte request budget. A raw PostgreSQL URL, generic one-word key, blank/duplicate schema name, or over-budget allowlist is rejected before source access. -- **Operator:** sets finite operation/statement timeouts plus row/byte/concurrency budgets. A source that exceeds any execution budget fails explicitly instead of producing a misleading partial model. -- **User cancellation:** cancellation is propagated across the port; the adapter must stop/abort as supported and return `Cancelled`, not a success receipt. -- **Source restart/disappearance:** a connection loss during metadata capture returns `SourceUnavailable`; no immutable snapshot is published from the incomplete capture. -- **Security review:** credentials remain adapter-owned and absent from request/domain objects; the port admits only a bounded opaque registry key while exact-schema authorization, request-memory bounds, and execution resource limits remain visible, typed, and testable. -- **Evidence replay:** two snapshots with the same observed source metadata produce the same v1 source-content digest regardless of input table order, source registry key, extractor revision, or observation timestamp; changing one observed metadata field changes that digest. +- **Data architect:** selects an approved opaque source key, exact schemas and explicit request-metadata budgets. Raw URLs, malformed keys, unknown keys, blank/duplicate schemas or over-budget allowlists fail before adapter execution. +- **Operator:** sets finite operation/statement timeouts plus row/byte/concurrency budgets. Runtime conformance must include the authorization step in the end-to-end deadline. +- **User cancellation:** the adapter propagates cancellation and returns `Cancelled`, not a success receipt. +- **Source restart/disappearance:** incomplete capture returns `SourceUnavailable`; no immutable snapshot is published. +- **Security review:** source execution requires registry-issued opaque capability evidence while credentials remain exclusively adapter-owned. +- **Evidence replay:** same observed source content yields the same v1 digest independent of table input order or provenance-only source/extractor/time values; a material metadata change changes the digest. ## References @@ -120,9 +134,10 @@ National Institute of Standards and Technology.

The canonical boundary has to prevent unauthorized source access, unbounded request metadata, caller-controlled snapshot identity, partial-success evidence, hidden blocking bridges, and a timeout policy that restarts after authorization. -Three independent admission/integrity gaps are material to this boundary. First, a syntactically valid caller-supplied digest is not proof that the digest was computed from the observed metadata. Second, captured catalog row/byte limits do not bound the caller-owned exact-schema allowlist retained before source access. Third, a registry capability is not an authorization boundary if the primary adapter method can still accept a raw request and succeed without registry resolution. - -A fourth execution-seam gap appears when the concrete adapter is asynchronous: a synchronous source port forces an async database adapter either to hide a nested executor/blocking bridge or to push scheduling workarounds into every caller. That would make cancellation and the single end-to-end operation deadline harder to prove at the canonical boundary. +The concrete PostgreSQL adapter is asynchronous. The port therefore needs an awaitable execution seam, but request admission and source authorization must remain provider-independent. The operation timeout is also end-to-end: registry authorization, connection, transaction, catalog queries, cancellation cleanup, and immutable snapshot construction may not each start a fresh copy of the same duration. ## Constraints - Source systems are read-only inputs; ConceptWeave does not own their business truth. -- Only a bounded opaque registry key may appear in request/domain objects: at most 128 bytes, lowercase multiword `snake_case`. Passwords, tokens, DSNs, URLs, shell-style connection parameters and provider connection objects do not cross this boundary. -- Key syntax is admission hygiene, not authorization. An authorized `SourceConnectionRegistry` must issue the opaque capability before a request can reach `SourceObservationPort` execution. -- Every request has a non-empty exact-schema allowlist, positive caller-selected schema-count/total-UTF-8-byte admission budget, and positive operation/statement-timeout, row, byte and concurrency bounds. -- Request authorization metadata is rejected before registry or database access when it exceeds policy. -- Exact source identifiers preserve original source text. Ordering may be canonicalized; identifier meaning is never normalized or truncated. -- Caller cancellation, source disappearance, malformed captures and resource exhaustion fail closed and do not produce a partial snapshot. -- Snapshot content identity is computed by Source Observation from complete owned observed metadata. Caller digest syntax is not content authority. -- Source registry identity, extractor revision and observation time remain provenance coordinates, not source-content bytes. -- Digest framing is versioned and domain-separated. -- Request construction and registry authorization remain deterministic pre-adapter operations. Live adapter execution is awaitable and returns a `Send` future; the port crate does not select or depend on an async runtime. -- The port remains provider-independent and free of PostgreSQL drivers, credentials, semantic inference, publication and LLM responsibilities. -- The concrete PostgreSQL adapter remains outside `conceptweave-domain`, `conceptweave-observation` and the port contract. Credential resolution stays inside its Anti-Corruption Layer. +- Raw DSNs, URLs, credentials, tokens, provider connection objects, and arbitrary SQL callbacks do not cross the port/domain boundary. +- A source key is a bounded opaque multiword `snake_case` registry identifier; syntax is not authority. +- `SourceConnectionRegistry` is an application-owned local authorization boundary. Remote credential/network work belongs in the adapter ACL after authorization. +- Every request carries a non-empty exact-schema allowlist, an explicit schema-count/UTF-8-byte admission budget, and positive operation/statement/row/byte/concurrency bounds. +- Request metadata is rejected before registry/database access when it exceeds policy. +- Exact source identifiers retain source spelling. Ordering may be canonicalized; names are never normalized or truncated for convenience. +- Caller cancellation, source disappearance, malformed captures, timeout, and resource exhaustion fail closed and never create a partial immutable snapshot. +- Snapshot content identity is computed by Source Observation from complete owned observed metadata; caller digest syntax is not content authority. +- Registry identity, extractor revision, observation time, and evidence location are provenance coordinates, not source-content bytes. +- The port crate does not select Tokio or another executor and does not import a PostgreSQL driver. ## Options considered -### Put execution policy into `conceptweave-observation` - -Rejected. That crate owns immutable observation facts. Driver execution policy would collapse fact identity and live-source concerns into one aggregate boundary. - -### Let every adapter define its own authorization, timeout and failure vocabulary - -Rejected. Resource safety and authorization would become adapter convention rather than a reusable product contract, weakening conformance and allowing silent divergence. - -### Keep `SourceObservationPort::observe` synchronous and bridge async adapters internally - -Rejected. The maintained PostgreSQL adapter line is asynchronous. A synchronous canonical port would either hide `block_on`/nested-runtime policy in the adapter or force callers to wrap a logically asynchronous source operation as blocking work. Both choices leak scheduling policy across the boundary and make cancellation plus one end-to-end deadline less auditable. - -### Treat a well-formed registry key as sufficient source authority +### Synchronous source port with adapter-local `block_on` -Rejected. Syntax cannot establish whether the caller is allowed to observe the named source. The earlier `SourceObservationPort::observe(&ObservationRequest, ...)` shape demonstrated the problem: an implementation could succeed without ever consulting `SourceConnectionRegistry` while satisfying the trait. +Rejected. It hides scheduling policy in the adapter, risks nested-runtime behavior, and weakens cancellation/deadline reasoning. -### Hard-code PostgreSQL's identifier-length default as request-memory policy +### Raw request accepted directly by the adapter -Rejected. PostgreSQL build defaults are provider implementation details, not ConceptWeave authorization-memory policy. Exact identifiers are source evidence and may not be truncated to fit a convenience constant. +Rejected. A syntactically valid registry key is not proof that the caller is authorized to observe that source. -### Pass a raw connection string or arbitrary SQL callback +### Original timeout duration only -Rejected. It would cross credential boundaries, make read-only enforcement unauditable and erase Source Observation ubiquitous language. +Rejected. An adapter entering after slow authorization cannot distinguish a nearly exhausted operation from a fresh one and will over-allocate connection/statement work. -### Trust an adapter-supplied SHA-256 string as snapshot identity +### Wall-clock deadline in the public contract -Rejected. Canonical `sha256:<64 lowercase hex>` syntax proves representation shape only, not binding to tables, columns or constraints. +Rejected. Wall-clock provenance is unnecessary for resource enforcement, adds serialization/clock-domain ambiguity, and leaks execution mechanics into the domain seam. -### Canonicalize through a general JSON or CBOR wire format now +### Provider-independent authorized envelope with a private monotonic start coordinate -Deferred. RFC 8949 deterministic CBOR is a suitable benchmark for a future cross-language artifact, but the current digest is an internal Rust aggregate identity. Introducing a general wire format now would create a serialization commitment the current boundary does not need. - -### Provider-independent request + authorized awaitable execution envelope + owner-computed digest - -Selected. `conceptweave-source-port` owns request admission, authorization capability binding, cancellation and fail-closed execution outcomes. `conceptweave-observation` owns immutable facts and source-content identity. The live execution method returns a runtime-neutral `Send` future while deterministic admission and registry authorization stay outside the adapter await point. +Selected. Authorization begins one monotonic operation budget before the registry lookup. The authorized envelope privately retains that coordinate and exposes only the remaining `Duration` to adapter code. ## Decision -`ObservationLimits` requires positive operation/statement-timeout, row, byte and concurrency limits. `ObservationRequestBudget` separately requires positive maximum schema count and total retained UTF-8 schema bytes. Caller/application policy selects these values explicitly; no provider-derived default is embedded. +`ObservationRequest` validates a bounded opaque source key, exact schema allowlist, `ObservationRequestBudget`, and `ObservationLimits`. `ObservationRequest::authorize` starts the operation's monotonic budget before the local `SourceConnectionRegistry` lookup. The lookup result is captured first; if elapsed time has exhausted `operation_timeout_ms`, authorization returns `ObservationRequestError::OperationTimeout` before propagating the registry result or admitting an adapter. This gives timeout precedence to an exhausted authorization step and preserves zero adapter/source/snapshot side effects. -`ObservationRequest` accepts a bounded opaque source registry key plus a non-empty exact schema allowlist. It rejects raw connection material, malformed/generic keys, blank or duplicate schema identifiers and over-budget authorization metadata before registry or database access. It sorts only the allowlist order for deterministic request identity. +A successful authorization returns `AuthorizedObservationRequest`, which binds the validated request to `ResolvedSourceConnection` 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. -`SourceConnectionRegistry` is the authorization boundary for the opaque key. `ObservationRequest::authorize` consumes a validated request, resolves its exact key through that registry and returns `AuthorizedObservationRequest`, which privately binds the request to the resulting `ResolvedSourceConnection`. `SourceObservationPort::observe` accepts only `AuthorizedObservationRequest`; a raw request or unknown key therefore cannot reach the adapter execution seam through the canonical port API. The authorization envelope contains no credential material. The concrete adapter resolves its already-authorized opaque capability to least-privilege credentials inside its own ACL. +`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. -`SourceObservationPort::observe` is awaitable and returns `impl Future> + Send`. `SourceObservationPort` and `ObservationCancellation` are `Sync`, allowing their shared references to cross an await point without introducing a runtime dependency. This is an execution-shape contract only: request validation, source-registry authorization, snapshot authority, and typed failure semantics are unchanged. +The concrete adapter must read the remaining budget before potentially blocking connection/transaction/statement/cancellation work and cap each stage accordingly. 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. -Registry authorization remains part of the same end-to-end operation policy as connection and catalog work. The concrete application/adapter integration must demonstrate that the configured operation deadline covers authorization, connection and all catalog work rather than treating authorization as an unbounded pre-step or restarting the budget when the awaitable adapter begins. ADR 0004 remains Proposed until that runtime conformance is implemented and verified. +`PostgresSchemaSnapshot` continues to compute its own domain-separated SHA-256 identity from complete exact observed metadata. Provenance coordinates stay separate from source-content identity. -`PostgresSchemaSnapshot` computes its own `sha256:` identity after exact table ordering is canonicalized. Digest input uses domain separator `conceptweave.postgres_schema_snapshot.v1` and explicit length-prefixed binary framing. Strings use exact UTF-8 bytes without Unicode/case/quoting normalization. Lengths are unsigned 64-bit big-endian, column ordinals unsigned 32-bit big-endian, and booleans/options/constraint variants/FK actions/match types/deferrability use explicit stable tags. Ordered composite-key and FK coordinates remain order-significant source evidence. +This ADR remains **Proposed**. The port can now represent and preserve the non-resetting budget, but no production PostgreSQL adapter or exact-head runtime conformance has yet proved the full decision. -The v1 envelope includes exact table identifiers; column name/ordinal/type/nullability/comment; PK/unique/FK/CHECK fields; optional FK reference behavior and targeted delete columns; validation/enforcement state; CHECK definition; and `NO INHERIT`. It excludes `source_connection_key`, extractor revision and observation time. Receipts expose only the owner-computed digest plus separate provenance coordinates. +## Test and evidence contract -SHA-256 follows NIST FIPS 180-4. A future framing revision must use a new domain/version and migration contract rather than silently reinterpret v1. A future published cross-language observation artifact may adopt deterministic CBOR under RFC 8949; v1 does not claim CBOR compatibility. +The current Source Observation lineage includes: -This decision does **not** claim a production PostgreSQL adapter exists. The next implementation must select a maintained Rust driver, resolve credentials only from the authorized opaque capability, establish explicit read-only session/transaction behavior, enforce all budgets and cancellation in execution, produce complete-or-fail immutable observations, and prove source-disappearance behavior against a frozen anonymized reference fixture. +- `5ee0e1edf8a2da527aefd4fe7ad2003d79b87ac6` → `301452ae2744080406f4075fe197c16d7c35cd2d`: owner-computed snapshot identity; +- `b7e54ae2b4fe9bea20d42b2d95e8c25c118a1f5f` → `94927ec3c7763c4b53cbcefd01b510030122d1db`, plus `8ed91afcf520efdd53c9103b332d3e277db29a03`: bounded request metadata and checked byte accumulation; +- `a372d6729364347315db1ad9a75efc49c779fbb9` → `5caf10b144b8254946e5d80840b0f200c0d36651`: registry-authorized adapter admission; +- `b2b83c0fdc78af11e3e0df8cf6993216dd9c6004` → `638be096f444fd22755160972285dbb9f0eb0364`: runtime-neutral awaitable source-port seam; +- `1f8f6a5875072f15325c063aa857c6da8e0accc1`: executable specification for partial and exhausted registry-budget consumption; +- `2a77a9012ef2b8323fe61ed3ba9986ee8ecae6b0`: private monotonic coordinate and remaining-budget API; +- `82222c194e974df8f24527ab3e9b0eb579823d2d`: timeout-precedence specification for a slow denied registry lookup; +- `235a892e8a6bd77ac5f33136980eb1fd14f30eaa`: timeout-precedence production repair; +- `1204b35376d739c123668c9eb92868eef1992bb7`: immediate static correction of an accidental enum-variant spelling regression in the preceding commit. -## Evidence +The remaining-budget tests are committed executable specifications, not claimed observed RED→GREEN.

Exact-head tests, strict Clippy/fmt/rustdoc, release build, owned coverage, security/dependency gates, and independent review are terminally valid. ## Risks and mitigations -- **Configuration without enforcement:** a concrete adapter can accept budgets but ignore them. Conformance must force timeout, row, byte, concurrency, cancellation and source-disappearance failures and prove no snapshot is returned. -- **Authorization bypass:** an implementation could otherwise use a syntactically valid raw key directly. Canonical adapter execution now requires `AuthorizedObservationRequest`; unknown keys fail before that value exists. -- **Credential-shaped caller input:** request keys are bounded multiword `snake_case`; actual credential lookup remains adapter-local. -- **Authorization deadline gap:** moving authorization ahead of adapter execution can accidentally exclude it from the total deadline. Runtime integration must prove one end-to-end operation budget across authorization, connection and catalog work before ADR acceptance. -- **Unbounded authorization metadata:** explicit schema count/byte ceilings apply before registry/database access. -- **Async scheduling leakage:** the canonical source operation is awaitable and runtime-neutral; adapters must not hide nested executors, and callers must not reclassify it as blocking work merely to satisfy the port. -- **Authorization drift:** exact schema allowlists remain exact, non-empty and unnormalized. -- **Partial evidence:** incomplete capture fails; immutable snapshot identity is issued only after complete construction. -- **Digest framing drift:** new observed identity fields require a new framing version/domain and regression fixtures. -- **Unicode/identifier normalization drift:** v1 hashes exact UTF-8 source bytes. -- **Cross-language replay:** if published replay becomes a requirement, adopt a standard deterministic representation rather than implicit Rust/serde layout. +- **Synchronous registry hangs:** the registry boundary is deliberately local and bounded; remote work is prohibited there. Runtime integration must keep that implementation property explicit and test it rather than silently using a network registry. +- **Deadline reset in adapter:** adapter conformance must use `remaining_operation_budget()` at each blocking stage; the original configured duration is a ceiling, not a fresh per-stage allowance. +- **Timing-coordinate leakage:** only remaining `Duration` is part of the adapter-facing API; no wall-clock timestamp or credential is carried. +- **Partial evidence:** immutable snapshot identity is created only after complete construction; failures never return a nominal success snapshot. +- **Authorization bypass:** the canonical adapter seam accepts only `AuthorizedObservationRequest`; a raw/well-formed key cannot invoke it. +- **Provider leakage:** PostgreSQL and runtime types stay in the adapter crate, not the port/domain contract. ## Effects -The Context Map is now caller/application → request admission + registry authorization (`conceptweave-source-port`) → authorized awaitable execution envelope → concrete source adapter → immutable `conceptweave-observation` facts. Semantic Discovery consumes completed observations/receipts only and never sees a live connection handle. Governance & Publication gains no source-execution authority. - -The request-memory budget and source authorization are separate invariants. A key can be syntactically valid yet unauthorized; an allowlist can be authorized in principle yet rejected because its retained metadata exceeds policy. Neither condition is silently converted into source access. - -Snapshot identity is owner-computed. Provenance remains separately inspectable through source registry, extractor, timestamp and evidence-location coordinates. - -## Concrete scenes - -- **Data architect:** selects an approved opaque source key, exact schemas and explicit request-metadata budgets. Raw URLs, malformed keys, unknown keys, blank/duplicate schemas or over-budget allowlists fail before adapter execution. -- **Operator:** sets finite operation/statement timeouts plus row/byte/concurrency budgets. Runtime conformance must include the authorization step in the end-to-end deadline. -- **Async application runtime:** awaits the authorized source operation directly; the port does not prescribe Tokio or another executor and does not permit a hidden blocking bridge to become the canonical behavior. -- **User cancellation:** the adapter propagates cancellation and returns `Cancelled`, not a success receipt. -- **Source restart/disappearance:** incomplete capture returns `SourceUnavailable`; no immutable snapshot is published. -- **Security review:** source execution requires registry-issued opaque capability evidence while credentials remain exclusively adapter-owned. -- **Evidence replay:** same observed source content yields the same v1 digest independent of table input order or provenance-only source/extractor/time values; a material metadata change changes the digest. +The Context Map is caller/application → bounded request admission → local registry authorization + shared monotonic budget → authorized awaitable execution envelope → concrete read-only source adapter → immutable Source Observation facts/receipts.

Snapshot construction independently rejects local table schemas outside the authorized request as defense in depth. - **Synchronous registry hangs:** the registry boundary is deliberately local and bounded; remote work is prohibited there. Runtime integration must keep that implementation property explicit and test it rather than silently using a network registry. - **Deadline reset in adapter:** adapter conformance must use `remaining_operation_budget()` at each blocking stage; the original configured duration is a ceiling, not a fresh per-stage allowance. - **Timing-coordinate leakage:** only remaining `Duration` is part of the adapter-facing API; no wall-clock timestamp or credential is carried. @@ -108,7 +114,7 @@ Required runtime acceptance before ADR status can become Accepted: ## Effects -The Context Map is caller/application → bounded request admission → local registry authorization + shared monotonic budget → authorized awaitable execution envelope → concrete read-only source adapter → authorization-bound immutable Source Observation facts/receipts.

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` resolves the exact key through the caller's local `SourceConnectionRegistry`, then requires the same policy boundary to authorize the exact sorted schema scope. `SourceConnectionRegistry::authorizes_schema_scope` defaults to deny, so a key-only registry cannot silently grant caller-selected schemas. Successful authorization binds the validated request to the opaque `ResolvedSourceConnection` inside `AuthorizedObservationRequest`. `SourceObservationPort::observe` accepts only that authorized envelope, so an unknown key or unauthorized exact schema scope cannot reach the adapter execution seam. Request construction remains deterministic and provider-independent. Registry authorization is a synchronous local policy boundary, not remote credential resolution: the operation's monotonic budget starts before both policy decisions, an exhausted authorization returns `ObservationRequestError::OperationTimeout`, and the authorized envelope privately retains the monotonic start coordinate.

The concrete adapter resolves the already-authorized opaque capability to least-privilege credentials inside its Anti-Corruption Layer. 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. -Each request also carries a caller-selected positive provider-independent authorization-metadata budget: maximum exact-schema count plus maximum total UTF-8 bytes retained across schema identifiers.

The initially proposed central repair retried the same token-bound request while retaining fail-closed behavior. +`ObservationRequest` admits only bounded opaque source keys, explicit exact-schema allowlists, bounded authorization metadata, and positive operation/statement/row/byte/concurrency limits. The local `SourceConnectionRegistry` must issue a bounded opaque immutable connection-policy binding and authorize the exact schema scope against the resulting `ResolvedSourceConnection`; both additional policy decisions default to fail closed. A known key without a binding cannot execute, and connection material such as a PostgreSQL DSN is rejected as an invalid binding rather than crossing the port seam. -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. +`AuthorizedObservationRequest` carries only the validated request, source key, opaque policy binding, and private monotonic operation-start coordinate. 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. -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. +`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. 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. -## Central control-plane evidence +These are source-reviewed executable contracts, not a claimed executed RED→GREEN. The next acceptance is unchanged-head Rust 1.98 Product/test/fmt/Clippy/rustdoc/release/owned-coverage evidence plus observed repair of any real failures. Only then should a concrete maintained Rust PostgreSQL adapter be added. -Protected central source is `.github/main@b5efbc2762e472e4a380b0503b1f050f76fbb008` at this snapshot. This is evidence only, not a mutable ConceptWeave dependency. +## Central owner evidence relevant to #35 -- 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. +Protected central source is `.github/main@fe827e133e7d867015d088777553e22736344c55` at this snapshot. `.github#1929` remains open and records that the app-token producer dispatches as `opencode-agent[bot]` while the effective authorization evidence has continued to reject that identity. ConceptWeave does not edit the central allowlist or replay stale failed handles. Owner acceptance requires the intended legitimate producer identities to be reconciled explicitly, followed by a newly emitted current-workflow repository dispatch that passes metadata validation and produces a terminal authenticated verdict. + +#35 also remains blocked by the separate Noema contradicted-capability review and contextual-orchestrator/Strix HTTP-500 failover lane.

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. -All local registry decisions are part of the same operation budget. Their results are captured before the elapsed-time check; if policy work exhausts `operation_timeout_ms`, authorization returns `ObservationRequestError::OperationTimeout` before propagating a policy result or admitting an adapter.

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 the registry has authorized the scope. Matching is exact and case-sensitive; no Unicode/case normalization broadens authorization.

It must not co 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.

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 single-writer handoff now carries local runtime successor `e3ac294b976d35f113fe9b920060f62c4a28f57f`: unique null-comparison evidence, explicit v2 framing and observed prerequisite verification repairs.
