Receipts as facts + +Treat: + +command +prescription +admission +committed transition fact + +as different concepts. + +A successful receipt should describe what Boatstack actually committed, not merely what was requested. + +When relevant to the patch, verify that receipt facts agree with: + +* executable program identity/fingerprint; +* transition identity; +* prior state revision; +* resulting state revision; +* admitted authority/capabilities; +* committed effects; +* verified postcondition. + +Look for false-success cases such as: + +success receipt emitted +→ state/effect later fails + +or: + +effect rolled back +→ receipt still records it as committed + +or: + +historical receipt +→ reused as fresh execution authority + +## 8. Program ABI and fingerprint integrity + +If the patch changes repository program loading, transition definitions, canonicalization, fingerprints, or program compatibility, check: + +* every kernel-observable semantic change affects program identity/fingerprint; +* irrelevant source formatting does not alter semantic identity; +* semantic ordering is not accidentally canonicalized away; +* duplicate transition identities fail rather than overwrite; +* transition identities remain unambiguous across programs; +* unknown executable fields fail closed; +* unsupported schema/runtime combinations cannot reach execution. + +Do not treat a raw source-file checksum as proof of executable-program identity unless that is actually the runtime contract. + +## 9. Runtime and repository isolation + +If the patch touches installation, launcher, runtime pins, updates, or migration, check the system as multiple repositories sharing one host. + +Look for cases where: + +updating repo A +→ changes shared host state +→ repo B executes a different runtime or becomes unusable + +Also inspect for: + +* temporary installer paths entering durable repository state; +* mutable global aliases becoming admitted runtime identity; +* candidate runtime being confused with active runtime; +* missing exact runtime falling back to latest/current; +* rollback restoring the wrong runtime/program identity. + +Repository selection and host storage may be shared mechanisms, but one repository's update must not silently change another repository's admitted runtime. + +## 10. Version and migration fidelity + +When behavior crosses Boatstack versions, check whether tests exercise real old/new semantics. + +A test that builds current source twice with different version strings does not establish compatibility with an actual older release when control law, state schema, launcher behavior, or protocol semantics changed. + +If the patch claims to fix or support a migration boundary, verify that the test fixture can actually instantiate that boundary. + +## 11. Tests as evidence + +Do not accept a passing test merely because its name describes the desired property. + +Inspect whether the fixture makes the failure possible. + +Prefer negative tests that prove the forbidden path is rejected. + +For a bug fix, ask: + +Could the old implementation pass this new test? + +If yes, the test may not establish the regression property. + +Also check whether mocks remove the exact concurrency, version skew, crash, authority, or filesystem condition the test claims to cover. + +## 12. Repository-authored control programs + +For changes to the programmable control boundary, keep this separation intact: + +repository program +→ declares control law + +Boatstack kernel +→ validates identity +→ checks compatibility +→ owns state freshness +→ admits authority +→ enforces effect boundaries +→ commits state +→ records facts + +A repository control program must not be able to reach around the declared program interface and mutate kernel semantics directly. + +## Finding requirements + +Report only actionable defects introduced by this pull request.
