Architecture Decision Records
This directory contains the Architecture Decision Records (ADRs) for the CORE project.
ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

Current frontier
Current as of 2026-05-29 (ADR-0183).
The development frontier has moved beyond the audit-passed foundations (ADR-0091–0125) into native multi-modal execution and autonomous calibration. Key active arcs include:
- Auditory Modality & CRDT Substrate (ADR-0180, ADR-0181, ADR-0183): Shifting from text-only to concurrent multi-modal pipelines. Introduces a lock-free Delta-CRDT shared vault substrate to eliminate thread contention under continuous vision/audio ingestion, and ships
audio_core_v1as a deterministic acoustic compiler lowerable to unit-versors. ADR-0183 stubs the serving-time ASR boundary, ensuring lexical extraction is either text-side or deterministically decoded underwrong=0. - Calibrated Attempt-and-Eliminate Learning (ADR-0175): Establishes a formal precision-only reliability ledger and ratio-gate using the one-sided Wilson lower bound (
conservative_floor). It separates the safe serving regime (wrong=0) from a sealed practice regime where failures are treated as elimination signals to prune the solver's search. - Incremental Comprehension & Verification (ADR-0164, ADR-0174): Transitioned sentence extraction from brittle regex sentence templates to a deterministic incremental reader based on shift-reduce over semantic categories. The reader is backed by held-hypothesis evaluation, lookback, and in-loop contemplation.
- Measurement & Evaluation Discipline (ADR-0166, ADR-0163-F2): Establishes the
capability-before-measurementrule to ensure eval lanes are only built when operators exist and can admit at least one case. F2 defines a confuser corpus discrimination probe rather than a mere coverage target.

Historical — accurate as of ADR-0125; see the Index for the complete, current list of domain promotions.
ADR-0080 (Contemplation Loop, Phase 1), ADR-0110 (math audit-passed), ADR-0111 (physics audit-passed), and ADR-0124 (systems_software audit-passed) have all landed — mathematics_logic, physics, and systems_software are at audit_passed=true; the contemplation loop emits read-only SPECULATIVE findings from frontier_compare reports. The remaining ratified domain (hebrew_greek_textual_reasoning) needs its own promotion ADR.
ADR-0122 attempted systems_software promotion and deferred honestly on a lane-shape contract mismatch (symbolic_logic output shape vs registered checker), resolved by ADR-0123's shape remap and successfully promoted via ADR-0124.
Open candidate directions (no ADR yet)
Historical — accurate as of ADR-0125; see the Index for the complete, current list.
- Multi-reviewer holdout governance and threshold signing. ADR-0105 seals holdout payloads with a single recipient identity; multi-reviewer governance remains future work.
Accepted reasoning-capable domains
Historical — accurate as of ADR-0125; see the Index for the complete, current list of domain promotions.
Per ADR-0106, audit_passed is contract-gated, not threshold-only: a domain row may carry audit_passed=true only when a reviewer-signed audit_passed_claims entry exists whose evidence-bundle digest reproduces byte-for-byte. ADR-0107 attempted the first worked promotion and the contract refused; ADR-0109 amended the threshold rules; ADR-0110 then successfully promoted mathematics_logic (the first domain at audit_passed=true); ADR-0111 promoted physics second without further contract change, retiring the "math-only" objection. The other two ratified domains remain at reasoning-capable pending their own promotion ADRs.
| Domain | Ratification ADR | Pack(s) | Evidence summary |
|---|---|---|---|
mathematics_logic |
ADR-0097 + ADR-0110 | en_mathematics_logic_v1 |
All nine ADR-0091 predicates pass; ledger row is audit-passed (first such promotion, ADR-0110); all three attached lanes meet ADR-0109 shape thresholds on public + holdout. |
physics |
ADR-0100 + ADR-0111 | en_physics_v1 |
All nine predicates pass; causal/modal operator coverage meets threshold; ledger row is audit-passed (second such promotion, ADR-0111); foundational_physics_ood 117/117 public + 39/39 holdout; shares inference_closure + fabrication_control results with math (distinct digest via domain_id). |
systems_software |
ADR-0101 + ADR-0124 | en_systems_software_v1 |
All nine predicates pass; transitive/causal operator coverage meets threshold; ledger row is audit-passed (third promotion, ADR-0124); all three attached lanes meet thresholds on public + holdout. |
hebrew_greek_textual_reasoning |
ADR-0102 + ADR-0103 | grc_logos_micro_v1, grc_logos_cognition_v1, he_logos_micro_v1, he_core_cognition_v1 |
First multi-pack ratification; all four packs carry uniform contract fields; causal/contradiction operator coverage meets threshold; ADR-0103 attaches Hebrew and Koine Greek fluency lanes with dev/public/holdout coverage. |
ADR chain notes
Forward Semantic Control closure — ADR-0022 through ADR-0026
ADR-0022 through ADR-0026 form a single coherent chain that closes forward semantic control as a non-stochastic, replay-deterministic, trace-evidenced mechanism.
- ADR-0022 establishes
AdmissibilityRegionand the contract that a region restricts the admissible token set at generation time. - ADR-0023 records proof evidence that the admissibility region is honored at the region-intersection level.
- ADR-0024 adds destination-side per-step admissibility and honest
InnerLoopExhaustionwhen all admissible candidates are rejected. - ADR-0025 adds rotor/frame admissibility when a region carries a
frame_versor. - ADR-0026 replaces static threshold tuning with ranked admissibility and a scale-invariant margin gate.
Runtime contracts for the chain are pinned in docs/runtime_contracts.md.
Pack-layer chain — ADR-0027 through ADR-0045
ADR-0027 through ADR-0045 establish the identity / safety / ethics pack architecture with deterministic remediation, audit completeness, telemetry, operator readout, audit-tour demo, pack measurements, a worked-example medical ethics pack, and long-context comparison measurements.
Evidence-governed domain chain — ADR-0091 through ADR-0111
ADR-0091 through ADR-0111 establish the current domain-ratification substrate and the audit-passed promotion gate that distinguishes contract-passing from demonstrated:
contract definition (0091)
↓
reviewer trust root (0092)
↓
validator / ledger enforcement (0093)
↓
negative-control fabrication lane (0096)
↓
reasoning-capable domain ratification (0097 / 0100 / 0101 / 0102)
↓
language-specific fluency lane attachment (0103)
↓
audit-passed promotion contract (0106 + 0109 amendment)
↓
worked audit-passed promotion (0110 — mathematics_logic, first)
↓
worked audit-passed promotion (0111 — physics, second; no contract change)
No domain claim should be treated as mature merely because a pack exists. reasoning-capable means the nine ADR-0091 predicates pass; audit-passed requires a reviewer-signed evidence-bundle digest that reproduces byte-for-byte from on-disk lane results.
The contract has been demonstrated end-to-end: refused once honestly (ADR-0107), amended once cleanly (ADR-0109), succeeded against mathematics_logic (ADR-0110), and succeeded against physics without further contract change (ADR-0111).
Comprehension-reader pivot — ADR-0164 and ADR-0165 (2026-05-26)
The GSM8K admissibility front-end is replaced. The regex sentence-template
parsing layer in generate/math_candidate_parser.py and
generate/recognizer_match.py is recognized as overfitting by
construction — it enumerates memorized surface shapes while pretending to
encode a closed grammar that English does not have.
-
ADR-0164 — Incremental Comprehension Reader. Word-by-word state accumulation over a closed set of semantic categories. The reader is a deterministic shift-reduce parser over categories, not over tokens. Output type is identical to the regex parser's output, so the binding-graph admissibility (ADR-0132/0133/0134/0135) downstream is unchanged. Operational lexicon lives in
language_packs/data/en_core_math_v1/alongside the existing packs. -
ADR-0165 — Regex Scope Rule. Structural invariant: regex is permitted only at the lexeme level (currency literal, fraction literal, percentage literal, time-amount, closed-set unit-noun), never at the sentence-structure level. The primitive set is a closed registry grown through the same contemplation → proposal → HITL review corridor that grows vocabulary.
These ADRs preserve every load-bearing piece of the prior work: the
binding graph (ADR-0132–0135), the solver / verifier / realizer
substrate (ADR-0116–0118), the capability-axis lanes G1–G5 and S1, the
HITL corridor (ADR-0150 / 0152 / 0155 / 0161), the wrong = 0 doctrine
and the replay-equivalence gate (ADR-0057, ADR-0114a). The
contemplation → proposal → review corridor architecture is reaffirmed
and its scope is generalized: it now ratifies lexicon entries,
categories, and lexeme primitives — not regex recognizers.
ADR-0163's diagnosis (the front-end is the bottleneck) is reaffirmed; its prescription (Phases B–E recognizer production) is partially superseded. ADR-0136 and its S-family have the same disposition.
Measurement-Capability Sequencing — ADR-0166 (2026-05-27)
Establishes the structural sequencing invariant: capability (operators, rules) must land on main and admit at least one test case before the eval lanes that measure it can be authored. Prevents noise of 100% refusing lanes from masking actual development priorities.
Calibrated learning and reliability — ADR-0175 through ADR-0177 (2026-05-28)
Establishes calibrated attempt-and-eliminate learning under a strict two-regime separation:
- Serving: Safe production path requiring
wrong=0via a strict, high-reliability Wilson lower bound gate. - Practice: Sealed evaluation path where mistakes serve as checkable elimination signals to prune solver paths.
Multimodal Audio modality & CRDT substrate — ADR-0180 through ADR-0183 (2026-05-29)
Shifts the engine toward concurrent multi-modal pipelines. Decouples physical lock contention on vision/audio from the logical manifold using Delta-CRDT sharding in Rust (ADR-0180), implements audio_core_v1 as a deterministic acoustic compiler (ADR-0181), and stubs ASR serving boundaries to prevent learned Whisper models from contaminating production serving paths (ADR-0183).
