• Keep BoundedContext realizes[n] and relationships[n] mappings usable across namespaces by treating them consistently as declared seams in both boundary and CROSS_MODEL_REF checks.
• Keep cross-namespace Component relationships[n] subject to CROSS_MODEL_BOUNDARY_VIOLATION; only BoundedContext strategic mappings receive the exemption.
• Prevent artifact download-test checkpoints from regressing or waiting indefinitely while retaining the payload and capacity assertions. This focused test repair accompanies the required Coverage run that stalled in the same suite; the observer race is reproduced deterministically, while the historical stall itself was not reproduced locally.

Closes #361

[coderabbitai]

Walkthrough

Cross-context validation now exempts realizes[] and relationships[] references only when the source is a bounded context. The artifact download tests now preserve the maximum observed read count and use a timed wait with diagnostics.

Changes

Strategic Mapping Validation

Layer / File(s)	Summary
Strategic mapping checks and tests rsworkspace/crates/trogon-atlas-server/src/validation.rs	A shared predicate recognizes realizes[] and relationships[] paths from bounded contexts. Both cross-context checks use the predicate. Tests cover bounded-context mappings and component relationships.

Artifact Download Read Tests

Layer / File(s)	Summary
Monotonic read notifications and bounded wait rsworkspace/crates/trogon-atlas-server/tests/artifact_download_budget.rs	Provider read notifications retain the maximum observed count. The blocked-read test adds a 10-second timeout and reports diagnostic state if the wait fails.

Cross-namespace realizes and relationships references from bounded contexts no longer raise spurious informational findings. Other entity kinds still get boundary diagnostics. No actionable merge risk remains.

Full details: Title check

Explanation

The title names the main change: cross-namespace realizes and relationships fields are now treated as declared strategic-mapping seams in validation. It uses the conventional fix(validation) prefix and is specific enough for a teammate scanning history. The raw summary also mentions a monotonic update change in a test file, which the title does not cover. That is a secondary change, so it does not make the title fail.

Full details: Linked Issues check

Explanation

Issue #361 requires that a BoundedContext whose realizes[n] points to a subdomain in another namespace not produce CROSS_MODEL_REF. At the reviewed head, validation.rs adds is_strategic_mapping_field(k, &o.from_field) to the declared_seam condition in the CROSS_MODEL_REF pass (around line 6703). The helper returns true only when kind == pb::EntityKind::BoundedContext and the field starts with realizes[ or relationships[. A bounded context realizing another namespace therefore takes the seam path. The test realizes_into_other_namespace_is_declared_seam in boundary_tests builds acme-orders realizing acme/orders and asserts zero CROSS_MODEL_REF and zero CROSS_MODEL_BOUNDARY_VIOLATION findings. This matches the #361 acceptance criterion and suggested fix. The workaround (adding the subdomain to members) is not changed. The relationships[n] handling is an extension beyond #361. The issue does not request it, so it is not a gap. The author's claim that the new tests fail without the fix was not re-run.

Full details: Description check

Explanation

The description names the concrete changes: BoundedContext realizes[n] and relationships[n] mappings are treated as declared seams in boundary and CROSS_MODEL_REF checks, Component relationships[n] remain subject to CROSS_MODEL_BOUNDARY_VIOLATION, and artifact download-test checkpoints are made monotonic with a timeout-based wait. These match the raw summary of validation.rs and artifact_download_budget.rs. It also references issue #361, which the objectives describe. The description is related to the changeset and is not off-topic or generic.

Full details: Out of Scope Changes check

Explanation

The diff includes changes in rsworkspace/crates/trogon-atlas-server/tests/artifact_download_budget.rs that do not relate to #361 or to the seam rule. The changes add record_read_entry (a max-based update of a watch channel), a new test provider_entry_notifications_remain_monotonic_when_reads_reorder, and a 10-second timeout with diagnostic panic in cancelling_a_blocked_provider_read_releases_its_reserved_capacity. These changes concern download provider-entry checkpoints. The PR description and linked issue do not mention download behavior. The new unit test exercises a local helper and does not cover the validation change. The validation.rs changes are related to #361: the helper is shared by the boundary check and CROSS_MODEL_REF pass, and the boundary_tests cover the same concept. The helper now also restricts the strategic-mapping exception to BoundedContext, so cross-namespace component relationships[n] now yield CROSS_MODEL_BOUNDARY_VIOLATION. That behavior change is tested but is not stated in the PR description. It is related to the seam rule, so it is not a demonstrated unrelated change. It should be confirmed as intended.

Resolution

Remove the artifact_download_budget.rs changes from this pull request, or move them to a separate pull request with its own linked issue. Update the PR description to state that cross-namespace component relationships[n] now produce CROSS_MODEL_BOUNDARY_VIOLATION, or restore the previous behavior for non-BoundedContext kinds if that change is not intended.

_{A rabbit checks the context trail,
Where bounded links now pass the test.
Read counts climb and do not fall,
A timed wait reports the rest.
The rabbit hops through tidy checks,
Then tucks the findings in its nest.}

- Line 8487: Update the predicate matching realizes and relationships fields to
accept the source entity kind, and require BoundedContext at both call sites
before applying a strategic mapping exemption. Add a regression case confirming
a cross-namespace Component relationship does not suppress

Verified 55375e7 after merging current main. The strategic boundary suite and all artifact budget tests pass, along with targeted Clippy, formatting and Proto checks. The observer ordering regression fails before its fix and passes afterward; the historical Coverage stall was not reproduced end to end.

In response to this review: the description now explicitly states that cross-namespace Component relationships produce CROSS_MODEL_BOUNDARY_VIOLATION, while the strategic exemption applies only to BoundedContext.

I am keeping the test-only observer repair in 55375e7 because required Coverage stalled in that suite. It preserves the original payload/capacity assertions and production code, adds a deterministic ordering regression and bounds the checkpoint wait. All eight boundary tests and four artifact budget tests pass; the historical stall itself did not reproduce locally.
