+# FIAM-WP-0002 — InterfaceCanon boundary review
+
+Handle State Hub request `cb3a7690-f145-4559-969f-c6f800994de0` from
+interface-canon for INTERFACE-WP-0004-T01.
+
+## T01 — Review pinned derivation and source provenance
+
+```task
+id: FIAM-WP-0002-T01
+status: done
+priority: high
+```
+
+Compared interface-model 0.1.1 at `1fc82ec6655ed286cea3be284e33d08e7b27edc3`
+with FIAM Core and Draft 1/Draft 6 explanations. Verified all four manifest
+source hashes against FIAM commit `135326756913363b098bcdee791628b5e864b8be`.
+The five requested semantic distinctions are preserved; no blocking corrections.
+
+## T02 — Apply boundary document and record acceptance
+
+```task
+id: FIAM-WP-0002-T02
+status: done
+priority: high
+```
+
+Added `docs/interface-canon-boundary.md` and README navigation. The receipt
+records reviewer identity, exact revisions, evidence, and limited acceptance.
+Validated source locators and local document links. No runtime changes.
+The review is available to the requesting repository in this committed receipt.
