# FINAL VERDICT - Status: PUBLISH - Event or contract: UserEmailVerified v2 - Canonical domain fact: The user's email ownership was confirmed by Auth, exactly once per user - Primary semantic risk: None material — Support Dashboard's use of verification_method is a local projection, not a meaning conflict - Affected contexts: Auth (producer), Marketing (consumer), Support Dashboard (consumer) - Required release action: None - Blocking evidence gap: None # EVENT IDENTITY | Element | Established Meaning | Evidence Status | Limitation | |---|---|---|---| | Domain fact | User's email ownership confirmed | CONTRACTUALLY DEFINED | None | | Occurrence condition | Verification link clicked or admin override | CONTRACTUALLY DEFINED | None | | Entity identity | user_id | CONTRACTUALLY DEFINED | None | | Lifecycle stage | Single terminal event, no further stages implied | IMPLEMENTATION-OBSERVED | Relies on producer's idempotency claim, not independently verifiable from evidence alone | | Effective time | verified_at | CONTRACTUALLY DEFINED | None | | Producer authority | Auth service, stated single source of truth | PRODUCER CLAIM | None material | | Contract version | v2 | CONTRACTUALLY DEFINED | v1→v2 diff not supplied; not material to this review's purpose | # CONTEXT PERSPECTIVE MAP | Context | Role | Interpreted Meaning | Trigger/Use | Contract Support | Unsupported Assumption | |---|---|---|---|---|---| | Auth | Producer | Email ownership confirmed, once per user | Publishes on link click or admin override | Full | None | | Marketing | Consumer | Same as producer meaning | Removes user from drip campaign | Full — uses only contractually defined fields | None | | Support Dashboard | Consumer | Same as producer meaning, plus displays method | Shows agents verification_method for support context | Full — verification_method is a defined enum, reading it doesn't alter meaning | None | # MATERIAL SEMANTIC COLLISIONS None found. All consumers interpret the domain fact identically; Support Dashboard's use of an additional field is a local projection (different subset of fields), not a different meaning. # FIELD-LEVEL AUDIT | Field | Producer Meaning | Consumer Meaning | Absence Meaning | Time Meaning | Status | Correction | |---|---|---|---|---|---|---| | verification_method | How verification occurred | Same, displayed only | Not nullable per schema | N/A | SEMANTICALLY COMPATIBLE | None required | # TEMPORAL AND PROVENANCE GAPS None material to this review's stated purpose. # CONTRACT ACTION PLAN 1. Release blocker: None 2. Required contract revision: None 3. Required producer change: None 4. Required consumer change: None 5. Validation or migration requirement: None 6. Non-blocking documentation improvement: Document that Auth's idempotency guarantee is enforced at the database layer, since two separate consumers currently rely on "exactly once" without that mechanism being contractually stated # PROPOSED CONTRACT CORE Not required — existing contract is sufficient as evaluated. # QUALITY CHECK Schema compatibility not conflated with semantic compatibility — confirmed via producer/consumer meaning match, not schema shape alone. Message emission not treated as unstated business proof — verification_method existing in schema doesn't imply a guarantee beyond what's stated. Producer and consumer perspectives evaluated separately in the Perspective Map. No delivery/ordering guarantee invented — idempotency reliance flagged as PRODUCER CLAIM, not treated as a contractual guarantee. Every remediation (the one documentation note) maps to the identity-limitation finding. Verdict follows PUBLISH rule: stable domain fact, compatible interpretations, no assumption exceeds contract. # INPUT INTEGRITY NOTES NONE.
