What it added |
| 6 |
Framework extraction — the event spine, ledger, tenant boundary and module contract packaged as @magpie/* (ADR-0008). |
| 7 |
Correctness — executor idempotency, token propagation, review-resume hardening, ledger logical-transition idempotency. |
| 8 |
AI runtime — evals + CLI + archive, pointer-flip audit and promote/rollback (ADR-0011), per-step routing (0012), tool contract (0013), review edit/resume (0014). |
| 9 |
Execution reliability — idempotency (ADR-0015), control plane, blob, jobs, webhooks, scheduler, reconciliation. |
| 10 |
Knowledge substrate — records, extraction, chunking, embeddings, vector store, retrieval, drift reconciliation; the hash-binding chain. |
| 11 |
Module composition — manifest registry, IdP tenancy, in-memory bootstrap, CDK constructs. |
| 12 |
Transactional substrate — unit of work, records, server bootstrap. |
| 13 |
Release governance — ADR-0016 and the INV-REL-* invariants, surface snapshots, anti-bypass greps; ADR-0017 records doctrine. |
| 14 |
Operational AI substrate — capability declarations (0020), per-transition rows and hash chain (0019), production embedder (0018), records-backed knowledge (0023), vector-as-cache (0031), OpenAI provider and provider fallback (0021), cost ceilings and rate quotas (0022), replay/recovery tooling. |
| 15 |
Streaming — gateway and provider streaming for Bedrock and OpenAI against the frozen ADR-0024 contract. |
| OEI |
Records migration runner (ADR-0033). |
| 0.6–0.7 |
Identity-first prompt resolution (0036), coalescing output projection (0037), gateway-enforced structured output (0039), relationship memory (0038, MEM-B), entity-scoped ledger history, streamed transition emission. |
- Substrate — 30 ADRs, 0007 through 0039. Accepted and implemented:
0007, 0008, 0011–0024, 0031, 0033, 0035–0037, 0039.
- Composition — 15 ADRs, 0001 through 0015, all Accepted.
