M2	L3	—
M3	L4	Full xAPI 1.0.3 + cmi5 conformance; SCORM 2004 statement mapping
M4	L4	Branching scenario statements
M5	L4	Multi-region + HIPAA tier

2. Gates

G1 — Domain

• Attempt, Statement, CompletionRecord aggregates + invariants.
• State machine open → closed.
• 95% unit / 80% mutation.

G2 — API

• xAPI 1.0.3 conformance.
• OpenAPI for internal.
• Idempotency on internal writes.
• cursor pagination.

G3 — Events

• progress.statement.stored.v1, .attempt.*, .completion.recorded.v1 registered.
• Outbox + inbox.

G4 — Sync

• Statement append_only; Attempt + CompletionRecord server_authoritative.
• Offline statements outbox 7-day.

G5 — AI

• No direct AI; data exposed to ai-gateway consumers.
• PII-redacted analytics firehose.

G6 — Observability

• Ingestion, projection, query dashboards.
• DLQ alerts.

G7 — Performance

• 10k statements/sec/region sustained.
• Transcript < 2s p95.
• xAPI query < 300ms p95.

G8 — Security

• Tenant iso green (RLS + tenant-hash partitioning).

• Signed-statement verification.
• GDPR saga participation.

3. SLOs

Outbox lag p99	< 30s

4. DoD

• Unit + integration + contract + xAPI conformance green.
• OpenAPI updated.
• Event schemas registered.
• Migrations fwd+back; replay test.
