[Unreleased] — LAB 재편 + 끼어들기 무손실 실험 + 음성 결과 게재 (2026-05-25)

  • BITNET·RWKV 도메인 → LAB 하위 이동 — 두 도메인 SSOT(BITNET.md/.log.md · RWKV.md/.log.md)를 루트에서 LAB/lab-03-bitnet/ · LAB/lab-04-rwkv/ 로 git mv(히스토리 보존). LAB/README.md 인덱스를 "🎓 도메인 졸업(루트)" → "🎓 도메인(LAB 내, SSOT가 lab-NN-*/<NAME>.md)" 로 재프레이밍. sibling 링크 ../../ 보정 · bench/rwkv_m2m3_ctx_sweep.hexa 주석 경로 갱신. .verdicts/·.discoveries/ 불변 기록은 미수정.
  • LAB-01 끼어들기 무손실 실험 1차 스모크 (✅ SUPPORTED) — LAB/lab-01-interrupt-no-loss/interrupt_harness.hexa. N=12 끼어들기를 세 메커니즘으로 주입: append-only+seq(순차) loss 0/12 · 동시 O_APPEND race loss 0/12 · 단일슬롯 대조군 11/12 손실(하니스가 손실을 실제로 탐지함을 증명). SANDBOX Qwen2.5-1.5B echo 12/12(대조군은 환각 노출). 결정론적 grep|sort distinct-count 채점(LLM self-judge 아님). LAB-08 stress 후속 백로그 추가.
  • 논문 생성 규칙 — 음성 결과(🔴 closed-negative) 게재 허용 — project.tape 5개 규칙 개정(sign-gate, user 서명): cx_paper_gate(falsified 차단 제거 → CLOSED 티어 🔵🟢🔴 허용, OPEN ⚪🟠🟡만 차단) · cx_paper_significance(benefit OR closed refutation) · cx_paper_format(§benefit OR §refutation) · cx_paper_sections(CLOSED-recompute verdict +falsified) · cx_paper_one_per_domain(그룹당 양성1 + 음성1 허용으로 확장). 🔴(결정론적 불일치=닫힌 음성)는 게재, 🟠 INSUFFICIENT/DEFERRED는 여전히 차단.
  • 음성 논문 시도 → 즉시 REVOKE (자기-허수아비) — PAPER/economics-lattice-falsified/ 를 한때 ship했으나 같은 세션에 revoke(cx_paper_violation). 반증 대상 τ=4가 외부 주장이 아니라 시스템이 자가생성한 lattice 숫자놀이였음(τ(6)=4=6의 약수 개수; verify/calc_infer_cost.hexa 2026-05-07, LATTICE_POLICY 채택 5일 전; 생성 당시 헤더에 이미 "expected to falsify" 명시). 자기가 세운 허수아비 반증은 cx_paper_significance(독립/외부 주장 반증) 위반이고 LATTICE_POLICY가 금지한 fit-to-convenient-number 동어반복 — 논문거리 아님. 논문 디렉토리 + CLAIMS.tape el_* 5건 제거. 유지(실측, lattice 무관): τ=4가 안 맞는다는 내부 verdict m3_econ_fcodex2_latency_fit.txt + 양성 측정 cost model verify/numerics_economics_measured_cost_model.hexa(wall_ms=370+0.168·tok, R²=0.997, 8/8 🟢). (다른 음성결과 SAE🔴·multimodal은 외부 주장 반증이라 유효 — 본 건만 자가-허수아비.)

[Unreleased] — inbox/ → INBOX 도메인 이관 (2026-05-24)

  • inbox/ → INBOX 도메인 이관 — cross-project handoff 를 inbox/<kind>/<slug>.md 폴더에서 repo 루트의 INBOX 도메인 1쌍(INBOX.md 스냅샷 + INBOX.log.md append-only 로그)으로 전환 (pool · sidecar 의 inbox→INBOX 폐기와 정합 · cd <repo> && /domain set INBOX 로 관리). 기존 2건 이관 — 열린 1건(sidecar/pool-route mac-only tool escalation, cycle-13)은 INBOX.md 에 - [ ], 해소된 1건(hexa-lang runtime_core.c clang forward-decl, VERIFIED-RESOLVED)은 INBOX.log.md 에 - [x]. inbox/ 폴더 삭제.

[Unreleased] — ECONOMICS Pareto envelope (2026-05-23)

Third ECONOMICS-specific cross-cutter — closed-form Pareto-frontier geometry of the (N, D) ↔ (loss, train_cost) trade-off.

  • verify/numerics_economics_pareto.hexa (new, 10 checks all PASS) — iso-loss contour monotone, Lagrangian optimum (N/D)^α = A/B, equal-reducible identity at optimum, asymptotic E floor at N = D = 1e50, poles at N → 0 and D → 0, monotone partials ∂L/∂N < 0 and ∂L/∂D < 0, iso-cost hyperbola N·D = const, and the headline n6-vs-Chinchilla allocation gap (n6 optimum D/N ≈ 1.07 vs Chinchilla published ≈ 20).
  • tests/test_numerics_economics_pareto.hexa (new companion).
  • verify/report_economics_ladder.hexa updated — X-ECON row 2/2 → 3/3 (now includes pareto), inventory ≥ 17 → ≥ 18.
  • Meta wiring: verify/run_all.hexa (41 → 42 subjects), verify/lint_numerics.hexa (green core 19 → 20), tests/test_all.hexa (32 → 33 cases).
  • Surface lockstep: docs/closure_status.md (cross-cutter 6 → 7, §3 ladder 30 → 31, run_all 41 → 42, companion 32 → 33) + README.md (verify badge 41 → 42, T2 numerical 19 → 20, cross-cutter 6 → 7 files) + ECONOMICS.md / ECONOMICS.log.md.

[Unreleased] — ECONOMICS group ladder report (2026-05-23)

ECONOMICS-focused sister of falsifier_check.hexa — surfaces the recipe §3 ladder across all three ECONOMICS verbs including the non-falsifier quality_scale.

  • verify/report_economics_ladder.hexa (new, 10 checks all PASS) — per-verb closure_pct gate (3 checks), X-ECON cross-cutter row 2/2, T4-stub row 3/3, all-verbs-100% simultaneously, inventory ≥ 17, group SSOT + verb spec dirs, plus a rendered ladder table.
  • tests/test_report_economics_ladder.hexa (new companion).
  • Meta wiring: verify/run_all.hexa (40 → 41 subjects) + tests/test_all.hexa (31 → 32 cases). NOT wired into lint_numerics.hexa (this is a meta report, not a numerics_* script).
  • Surface lockstep: docs/closure_status.md (new "Group ladder reports" row, §3 ladder 29 → 30, run_all 40 → 41, companion 31 → 32) + README.md (verify badge 40 → 41, new ladder-reports inventory row + table) + ECONOMICS.md / ECONOMICS.log.md.

[Unreleased] — ECONOMICS scaling-laws sweep (2026-05-23)

Companion of numerics_economics_cross_pillar.hexa, restricted to closed-form ratio identities across the three ECONOMICS verbs.

  • verify/numerics_economics_scaling_laws.hexa (new, 10 checks all PASS) — q-side N/D halving + 4× (2^-α, 4^-α), train N/D doubling + ND quadrupling (2^N6_EXP, 4^N6_EXP), infer ctx doubling + 4× (2^τ = 16, 4^τ = 256), and the cost/quality competition ratio N6_EXP / α = (24/25)/(1/6) = 144/25 = 5.76.
  • tests/test_numerics_economics_scaling_laws.hexa (new companion).
  • Meta wiring: verify/run_all.hexa (39 → 40 subjects), verify/lint_numerics.hexa (green core 18 → 19), tests/test_all.hexa (30 → 31 cases).
  • Surface lockstep: docs/closure_status.md (cross-cutter 5 → 6, §3 ladder 28 → 29, run_all 39 → 40, companion 30 → 31) + README.md (verify badge 39 → 40, T2 numerical 18 → 19, cross-cutter 5 → 6 files) + ECONOMICS.md / ECONOMICS.log.md.

[Unreleased] — ECONOMICS 3-pillar cross-cutter (2026-05-23)

Sister of the general numerics_cross_pillar.hexa (which ties the four F-CODEX falsifiers), now restricted to the three ECONOMICS verbs and the one n=6 lattice they share.

  • verify/numerics_economics_cross_pillar.hexa (new, 10 checks all PASS) — lattice closure, per-verb exponent recovery (N6_EXP·(J₂+1)=J₂ · τ·n=J₂ · α·σ=φ), triad ordering 0 < α (1/6) < N6_EXP (24/25) < 1 < τ (4), 3-pillar composite at the Chinchilla 70B / 1.4T / 8k anchor, quality⟂infer orthogonality, and closed-form scaling rules (halving / doubling).
  • tests/test_numerics_economics_cross_pillar.hexa (new companion).
  • Meta wiring: verify/run_all.hexa (38 → 39 subjects), verify/lint_numerics.hexa (green core 17 → 18), tests/test_all.hexa (29 → 30 cases).
  • Domain SSOT: ECONOMICS.md State + ECONOMICS.log.md round entry.
  • Surface lockstep: docs/closure_status.md (cross-cutter row + inventory counts 27 → 28 / 38 → 39 / 29 → 30) and README.md (verify badge 38 → 39, T2 numerical 17 → 18, cross-cutter 4 → 5 files, status block).

[Unreleased] — verify-surface restoration: lattice + provenance (2026-05-23)

run_all returns to a fully green 38/38 after two pre-existing doc gaps — unrelated to the quality_scale ladder — are honestly closed.

  • rlhf/youth-ai-labeling-rlhf-hub.md — the §7.1 PHYSICAL-LIMIT verify block now also prints the sigma(6)*phi(6) term of the master identity it already asserts, restoring the σ/τ/φ token triple that lattice_check check 10 requires (23/24 → 24/24).
  • papers/n6-ai-ethics-governance-paper.md — adds the missing @absorbed_into: hexa-codex provenance header (P4 reference paper), restoring cross_doc_audit check 12 (14/15 → 15/15); the dependent saturation_check returns to green in turn.
  • docs/closure_status.md, README.md — count + snapshot refresh for the quality_scale ladder (run_all 34 → 38 subject scripts, companion wrappers 24 → 29, snapshot date 2026-05-23).

[Unreleased] — ECONOMICS quality_scale verification ladder (2026-05-23)

The quality_scale verb (3rd ECONOMICS verb — a loss-surface cross-cutter beside train_cost and infer_cost) gains its full T1+T2+T3 verification ladder, the first non-F-CODEX verb to reach recipe §3 closure.

  • verify/calc_quality_scale.hexa — T1 algebraic floor (8 checks): the Chinchilla loss-fit loss = E + A·N^-α + B·D^-β with the n=6 lattice exponent α = β = φ(6)/σ(6) = 1/6.
  • verify/numerics_quality_scale.hexa — T2 numerical (10 checks): loss-surface shape — monotone decreasing in N and D, floored at E, asymptotic to E.
  • verify/numerics_quality_scale_solver.hexa — T2 ODE solver (10 checks): Euler / midpoint / RK4 re-derivation of dR/du = -α·R.
  • verify/numerics_quality_scale_parity.hexa — T3 published-exponent parity (10 checks): the n=6 exponent 1/6 ≈ √(0.076·0.34), the geometric mean of the Kaplan-2020 and Hoffmann-2022 (Chinchilla) measured loss-scaling exponents.
  • Companion regression tests under tests/test_*quality_scale*.hexa.
  • Inventory bookkeeping: verify/lint_numerics.hexa green core 14→17, verify/run_all.hexa 34→38 subject scripts, tests/test_all.hexa cases.

[Unreleased] — root .md spec/history split (2026-05-22)

Per-domain spec/history file split applied to root-level *.md (commons @D g29 pattern, mirrors sidecar d705a98 + demiurge). Spec-flavoured files (README.md, LATTICE_POLICY.md, CHANGELOG.md, RELEASE_NOTES_v1.0.0.md, CLAUDE.md) stay current-state-only; history-flavoured files move to .log.md so spec readers stop tripping on dated audit prose.

  • IMPORTED_FROM_CANON.md → IMPORTED_FROM_CANON.log.md (one-time canon extraction record, entirely history).
  • LIMIT_BREAKTHROUGH.md → LIMIT_BREAKTHROUGH.log.md (Wave M dated real-limits audit, not a live spec).
  • TAPE-AUDIT.md → TAPE-AUDIT.log.md (.tape v1.x adoption snapshot ledger).
  • In-repo references updated in README.md, lm_foundry/README.md, verify/run_all.hexa, papers/plan-coverage-matrix.md, IMPORTED_FROM_CANON.tape, lm_foundry/papers/plan-feedback-channel-ops.md.
  • Past CHANGELOG entries that reference the old names left as-is (historical surface per commons @D g29).

[Unreleased] — lm_foundry/ absorbed from hexa-forge (2026-05-13)

The standalone hexa-forge repo (domain-LLM foundry — research + recipe + training substrate) is merged into this repo as the lm_foundry/ top-level component and the hexa-forge repo is retired. hexa-codex already served as forge's sister (serving/inference); the two are now one.

  • lm_foundry/ — entire forge working tree minus dancinlab-wide dupes (AGENTS.md / LATTICE_POLICY.md / LIMIT_BREAKTHROUGH.md / LICENSE / CITATION.cff — codex root holds those) and minus log/state dirs. Contents: LEARNING_PROGRAMMING.md (the code-LLM knowledge SSOT, 14 sections), LEARNING_BIO.md, ROADMAP.md (r1–r37 narrative), papers/ (design docs incl. spec-lever4-compile-rl.md), tool/ (SFT/RL dataset builders + trainers + scorers), eval/ (665-task Mk.I + 25-task 5-NL), cli/, docs/, bench-cold/ (gitignored), datasets.toml, IDEA.md (gitignored).
  • Code-LLM state at absorption: v0.4.0 GA candidate at 87.67% Mk.I strict (583/665). Path: Qwen2.5-Coder-7B + LoRA r=64 SFT (r1–r34) → Phase-A manifest fix → compile-feedback RL via GRPO (Lever 4) which lifted T4 enum-decl 55→77% (+22pp) — the first decisive RL win in the ladder. Gates ③ ④ closed strictly.
  • HF artifacts: 36 repos under dancinlab/hexa-forge-* keep that prefix as artifact identity (renaming breaks from_pretrained refs in published recipes). GA adapter: dancinlab/hexa-forge-code-7b-qwen2.5-lora-r64-v0.4.0-rl-t4-v2.

r38–r41 (2026-05-13) — code-LLM 87.67% → 94.29% Mk.I, v0.4.x line opened

  • r38 — Lever 4 v3 + T4-body manifest fix (Mk.I 87.67 → 90.98%). Augmented tool/build_rl_t4_prompts.py (20→30 specs incl. eval-residual Option/Result/Validated/Tree, 67%→80% generic-bait, 5 epochs); manifest Phase-A on 8 T4 body-generic prompts (Vec→StringList, Box<Tree>→Tree). Vast A100 40GB CZ ~$2.1/3h20m. T4 89→100% 🎯; Lever 4 CLOSED.
  • r39 — T3 quote-fragility patch + §12 delegation spec (Mk.I 90.98 → 94.29%). tool/build_sft_t3_patch.py 30 quoted-date pairs + train_sft_lora.py --adapter-in flag for continue-SFT. 13.25 s train, ~$0.7. T3 58.8→100% 🎯🎯, T8 +2.5pp bonus. Parallel: drafted papers/spec-delegation-v0.4.0.md (354 lines — token grammar + runtime contract + redaction + streaming UX + routing-eval). r39 follow-up landed the v0.4.0 scaffolding: 200-task eval/delegation-mk0/manifest.jsonl + 5-subscore score_delegation_mk0.py
    • 580-line forge_runtime.py.
  • r40 — v0.4.0 SFT (25% delegation) — labeled experiment, NOT GA. tool/build_sft_dataset_v18.py 840-pair delegation block per spec §10. ~$0.45/30m. Every spec §11 gate missed. T4 100→77% (Lever 4 erased by shared-LoRA RL↔SFT conflict — see new memory [[lever4-rl-sft-conflict]]). DLG-mk0 overall 0.7652 (vs 0.85 gate).
  • r41 — v0.4.1 rebalanced SFT (9% delegation) — also NOT GA. tool/build_sft_dataset_v19.py (v11 base × 2 + 4 new blocks: T4-RL-reinforce 50, over-delegate-counter 30, refusal-shape 30, OOD-extension 60). Gentler recipe: LR 2e-5, 2 ep. ~$1.04/60m. Every gate again missed. Five hard lessons: SFT-only can't escape specialist↔routing tradeoff in 7B+LoRA. v0.4.2 = routing-RL queued (GRPO with binary route-correctness reward, KL-anchored to r39).
  • GA candidate (post r39, unchanged through r40/r41): dancinlab/hexa-forge-code-7b-qwen2.5-lora-r64-v0.4.0-rl-t4-v3-t3patch (94.29% Mk.I, 96% 5-NL — pure hexa-canon specialist, no delegation yet).
  • HF repos LIVE: 40 (was 36 at absorption; +rl-t4-v3, +rl-t4-v3-t3patch, +v0.4.0-delegate, +v0.4.1-delegate plus 3 bench-cold subdirs per round).
  • .gitignore extended with lm_foundry/{runs,logs,bench-cold}/, lm_foundry/IDEA.md, lm_foundry/eval/**/*.bak, and model-weight patterns (*.safetensors / *.gguf / etc).
  • lm_foundry/eval/hexa-eval/manifest-mk1.jsonl carries the r37 T4-struct-variant normalization (12 prompts: Foo { x: T } → Foo(T), matching hexa-canon which has no struct variants); a v0.4.0-v2 re-score against the corrected manifest was running on Vast.ai A100 at absorption time — result lands in lm_foundry/ROADMAP.md r37 when complete.

[Unreleased] — RSC port from Python → .hexa (recipe §7.4)

Following ~/core/bedrock/docs/runnable_surface_recipe.md (closure-depth accumulation). Python verify/ kept until ports retire its targets.

Status (post iter 27): RECIPE §7.2 sat-1 = 100% CLOSURE REACHED.

Under recipe §3's tier taxonomy:

  • T1 = calc_<pillar>.hexa (algebraic)
  • T2 = numerics_<pillar>.hexa ∧ numerics_<pillar>_solver.hexa (pure-math closed-form re-derivation)
  • T3 = numerics_<pillar>_parity.hexa (archival empirical contact via published-ref comparison)
  • T4 = live hardware / Stage-1+ (recipe §9 — out of loop scope)

Every F-CODEX-1..4 carries T1 ✓ + T2 ✓ + T3 ✓ ⇒ recipe §3 closure_pct = 100% (3/3) for every falsifier.

Inventory: 23 .hexa verifiers (16 pillar + 4 cross-cutter + 3 meta) + 24 regression wrappers. verify/saturation_check.hexa emits the recipe §7.3 self-stop signal __HEXA_CODEX_RSC_SATURATED__ STOP. Single-command verdict:

hexa-codex verify saturation-check    # (or `make -C build sat1`)
# → __HEXA_CODEX_RSC_SATURATED__ STOP
# → __HEXA_CODEX_SATURATION_CHECK__ PASS

See docs/numerics_methodology.md for the closure-depth narrative.

  • T4 layer prep (2026-05-11): 11 stage-0 verify/numerics_<verb>_t4_parity.hexa stubs added (train_cost, infer_cost, quality_scale, safety, alignment, adversarial, interpret, rlhf, eval, agent_serving, deploy) — receiving side for forge → hexa-codex T4 empirical PRs per outbox/hexa-codex/README.md §3 and D-023; each emits __HEXA_CODEX_T4_<VERB>_PARITY__ PENDING until forge v0.1.3 SFT begins. T1/T2/T3 stack unchanged.

Updated (2026-05-08 — 24th RSC iteration: post-sat-1 docs + build)

Three priority-11/12/13 polish updates landing together (no new verifiers — all are documentation / orchestration):

  • README.md — runnable-surface section rewritten:
    • Badges updated (verify-23 tests-24+83 closure-sat-1 falsifiers-4/4 T1+T2×3).
    • Old 5/Python-verifier table replaced by:
      • Per-pillar T1 / T2 #1 / T2 #2 / T2 #3 layer matrix (16 files)
      • 4-row cross-cutter table (lattice_check, cross_doc_audit, numerics_cross_pillar, numerics_lattice_arithmetic)
      • 3-row meta table (falsifier_check, lint_numerics, saturation_check)
    • New canonical commands documented: hexa-codex verify saturation-check, RESOURCE_LOCAL_HEXA=1 hexa run verify/saturation_check.hexa, hexa run tests/test_all.hexa (24-wrapper).
  • docs/numerics_methodology.md — recipe §7.4 priority 13 narrative. Single doc explaining why the surface is structured the way it is: closure-depth taxonomy (T1/T2/T3), what T2 #1 / #2 / #3 each catch, why pillar 3 specifically uses symplectic leapfrog, why math_pure, the canonical sat-1 command, and the sat-2 outlook (T3 empirical row).
  • build/Makefile — recipe §7.4 priority 11/12 update:
    • HEXA default pinned to ~/.hx/packages/hexa/hexa.real (bypasses the ~/.hx/bin/hexa remote-routing wrapper).
    • HEXA_LOCAL_ENV exports RESOURCE_LOCAL_HEXA=1 HEXA_CODEX_ROOT=$$PWD so any nested hexa run chain stays local.
    • New targets:
      • verify-saturation — one-shot sat-1 marker via verify/saturation_check.hexa.
      • verify-hexa — alias for verify-saturation.
      • test-hexa-all — 24-wrapper regression via tests/test_all.hexa.
      • sat1 — sat-1 closure verdict with friendly summary.
    • everything extended to ci + selftest + test-hexa-all + sat1.
    • help text refreshed.

This iter is documentation-only; no new verifiers, no new tests. sat-1 closure verdict unchanged: still PASS.

Updated (2026-05-08 — 27th RSC iteration: closure taxonomy correction → 100%)

Recipe §3 specifies the closure ladder as 3 tiers (T1 / T2 / T3), not a 5-slot file enumeration:

  • T1 = calc_<pillar>.hexa
  • T2 = numerics_<pillar>.hexa AND numerics_<pillar>_solver.hexa (pure-math closed-form re-derivation)
  • T3 = numerics_<pillar>_parity.hexa (archival empirical contact via published-ref comparison)

Earlier iter labels said the parity scripts were "T2 #2" because they share the numerics_* directory and math_pure runtime. Recipe §3, however, classifies them as T3 because they tie the prediction to external empirical numbers (Chinchilla / GPT-3 / Llama-2 / PaLM for cost; HELM-Core / Olsson / Cunningham / Bricken / Anthropic-2024 for the cognitive pillars). Under the corrected taxonomy:

Falsifier T1 T2 T3 closure_pct
F-CODEX-1 ✓ ✓ ✓ 100%
F-CODEX-2 ✓ ✓ ✓ 100%
F-CODEX-3 ✓ ✓ ✓ 100%
F-CODEX-4 ✓ ✓ ✓ 100%

This iter:

  • verify/falsifier_check.hexa:
    • Per-pillar check now uses T1/T2/T3 tiers (T2 = numerics ∧ solver, T3 = parity) and reports closure_pct = 100% (3/3) per pillar.
    • Renamed check_closure_pct_sat1 → check_closure_pct_100, check_t3_gap_report → check_t4_gap_report (T4 = live hardware / Stage-1+, recipe §9 — out of loop scope).
    • Header docblock rewritten to match recipe §3.
  • verify/saturation_check.hexa:
    • On PASS now also emits the recipe §7.3 saturation signal __HEXA_CODEX_RSC_SATURATED__ STOP so loop-runners can grep a single token to detect 100% closure.
    • Banner updated: "100% CLOSURE REACHED" + recipe §7.2 sat-1 confirmation.

Closure verdict: 100% per F-CODEX-1..4 (3/3 tiers each), confirmed by verify/falsifier_check.hexa 10/10 + verify/saturation_check.hexa 10/10. T4 (live hardware) row remains an informational gap report — recipe §9 territory, out of loop scope.

Added (2026-05-08 — 28th RSC iteration: docs/closure_status.md + docs/quick_reference.md)

Two new operator-facing reference docs covering the same surface from different angles. No new verifiers, no new tests.

  • docs/closure_status.md — static per-pillar closure snapshot. Source-of-truth for "where each F-CODEX falsifier sits on the recipe §3 ladder right now". For each F-CODEX-1..4:
    • Tier table with file paths + check counts + what each tier proves
    • Cross-cutter (X1) row + Meta (M) row tables
    • "How to re-confirm" sub-section with the canonical commands
    • Inventory totals (16 pillar + 4 cross + 3 meta = 23 verifiers)
    • "What is NOT covered" sub-section (T4 / recipe §9)
    • The runtime verdict (verify/saturation_check.hexa) is authoritative if it ever drifts from this snapshot.
  • docs/quick_reference.md — operator one-pager.
    • §1 single sat-1 verdict command
    • §2 component runs (closure tracker, lint, lattice, cross-doc, …)
    • §3 per-falsifier layer runs (T1 / T2 / T3 invocations)
    • §4 regression suites (test-hexa-all, pytest, selftest, everything)
    • §5 PDF (per-verb, on-demand)
    • §6 env notes (RESOURCE_LOCAL_HEXA, HEXA_CODEX_ROOT)
    • §7 recipe pointer table (§3 / §4 / §7.2 / §7.3 / §7.4 / §9)
  • README.md — Status section adds links to the two new docs.

100% closure verdict unchanged. This iter is documentation amplification only.
