| Subsystem | Spec Reference | Spec Authority | Implementation Maturity | Promotion State | Spec-Impl Alignment | Drift Risk | Last Alignment Review | Owner | Target | Notes |
|---|---|---|---|---|---|---|---|---|---|---|
| Data Types | spec/t81-data-types.md |
Frozen | Implemented | Verified | High | Low | 2026-03-06 | @t81dev | N/A (maintain) | Frozen DCP surface. Audit 2026-02-27: Cell signed-overflow UB fixed, T81Float signed-zero canonicalized, T81Map/T81Set enforcement hardened. Documentation reorganization completed 2026-03-06. |
| TISC ISA | spec/tisc-spec.md |
Frozen | Implemented | Verified | High | Low | 2026-03-06 | @t81dev | N/A (maintain) | Frozen DCP surface. Freeze integrity enforced by check_tisc_freeze_integrity.py. Documentation reorganization completed 2026-03-06. |
| T81VM | spec/t81vm-spec.md |
Beta | Beta | Beta | Medium | Low | 2026-03-08 | @t81dev | 2026-04-15 | Non-JIT path DCP-verified. FW-02 closure landed: Axion opcode pre-dispatch moved outside main VM switch. RFC-0026 phase-1 extended: all six opcodes have runtime semantics. TLOADHASH null-canonfs SEGFAULT fixed (2026-03-08): null-guard with hash-format validation; set_canonfs_root() API added to IVirtualMachine; DecodeFault/BoundsFault taxonomy enforced. 332/332 tests passing. |
| T81Lang | spec/t81lang-spec.md |
Draft | Beta | Beta (impl) / Draft (spec) | Medium | Low | 2026-03-08 | @t81dev | 2026-05-15 | BG-06/BG-07/BG-08/BG-09 closed. Frontend refactor complete (2026-03-08): typed AST (Expr::resolved_type), unified builtin registry (kBuiltinTable, 130 entries), IRGen extracted to ir_generator.cpp; SA dispatch ordering fixed (table-driven fallback after custom handlers). 332/332 tests passing. |
| Axion Kernel | spec/axion-kernel.md |
Draft | Alpha | Alpha | Medium | Medium | 2026-03-06 | @t81dev | 2026-04-30 | §1.6/1.9 implemented (bounded). AX-M5..M7 evidence closures landed; pending Beta candidacy review cycle. §2.5 remains deferred. Documentation reorganization completed 2026-03-06. |
| T81Graph | Surface inventory (non-normative) | Draft | Draft | Experimental | Medium | Medium | 2026-03-06 | @t81dev | 2026-05-15 | VM opcode lowering and lang-side serialization wiring complete with determinism coverage. Surface remains governed non-DCP until promotion. Documentation reorganization completed 2026-03-06. |
| Cognitive Tiers | spec/cognitive-tiers.md |
Draft | Concept / Experimental | Experimental | Low | High | 2026-03-08 | @t81dev | 2026-06-15 | Experimental, non-DCP. RFC-0000 §6 (2026-03-08): TierId::Tier6 (T6561, 3^8) added; MeshReflector/MonadState types in tier6/distributed_monad.hpp; Θ₇ entropy containment gate; promotion.cpp Tier5→Tier6 promotion path. Tiers 0–6 now modelled. |
| Hanoi VM | spec/rfcs/RFC-0000 |
Draft | Alpha | Experimental | Low | Medium | 2026-03-08 | @t81dev | 2026-06-30 | RFC-0000 §4 (2026-03-08): Kernel::boot() interface added; InMemoryKernel evaluates Θ₁–Θ₉ via check_ethics() before first spawn; 81-slot scheduler cap enforced (Error::SchedulerFull); EthicsViolation/CapabilityDenied traps in vm::Trap enum. Still experimental/non-DCP; no formal spec beyond RFC-0000 normative clauses. |
| Governed llama.cpp | docs/records/archive/project-reports/llama-governed-repro.md (guidance) |
Non-normative | Experimental | Governed non-DCP | Medium | Medium | 2026-02-28 | @t81dev | 2026-04-30 | Classified governed non-DCP (DEC-003). Practical reproducibility only. Promotion requires governed AGI pipeline. |
| Layer | Paths | Determinism Status | Promotion State | Governance Gate |
|---|---|---|---|---|
| Deterministic Substrate | core/types, core/isa, core/vm, include/t81/** |
DCP / registry Verified | Verified | Freeze enforcement + DCP release discipline |
| Governance Kernel | kernel/axion |
Partially verified, scope-bounded | Alpha | Axion evidence milestones + incident-response |
| AGI Runtime / Research | runtime/tracing, experimental/*, cognitive tiers |
Non-DCP unless promoted | Experimental | Governed AGI promotion pipeline |
| Governed Inference | third_party/llama.cpp, tooling/model/, CLI llama-run |
Governed non-DCP | Experimental | Governed AGI pipeline + release boundary classification |
