What this project is + +- **Model:** `fsi-anomaly` (family: `fsi_felon-*`), a **25.4M-parameter** + custom liquid-architecture language model, trained ENTIRELY on an 8-core ARM + tablet, no GPU, no big-compute. +- **Purpose:** an on-device, offline research/journalism partner for + dark-web/.onion research — verify and debunk claims, find patterns and + discrepancies, inspect history/what-was-said vs what-the-record-shows, + abstain when unverifiable. Built for conspiracy researchers, whistleblowers, + and anyone who wants the truth without the paywall. +- **Owner/team:** solo developer (licensed electrician, no funding), building + under **FERRELL SYNTHETIC INTELLIGENCE (FSI)**. Goal: a free open-source + small-model family + enough HF downloads for grants/loans. +- **Launch identity:** Hugging Face user `FerrellSyntheticIntelligence`, + repo `fsi-anomaly` (`hf_repo_v8/` is the prepared launch repo). GGUF Q8 + export at release, honest eval card, easy install. + +## 2. Where we stand right now (2026-08-09) + +- **The fluent base is safe and intact:** `ckpt/tiny25m/model_best.pt` + (coherent TinyStories-era English, ppl ~8.3).

Research log (papers that shaped decisions) + +- TinyStories (2305.07759) — tiny models speak coherently only inside a simple + constrained domain; ~28M coherence threshold for open-ended English. +- phi-1 (2306.11644) — textbook-quality curated data; small models leave clean + when data is clean. +- LIMA (2305.11206) — ~1k curated examples shape style IF the base is strong; + quality > quantity, but format ≠ reasoning. +- Don't Stop Pretraining (2004.10964) — second-phase in-domain pretraining + beats fine-tuning; no restart needed (our CONTINUE decision). +- LoRA (2106.09685) + EWC (1612.00796) — adapt on frozen base, don't restart. +- LFM2 (2511.23404) — staged curriculum SFT → preference → merging on ONE base. +- DeepSeek-R1 (2501.12948) / Let's Verify Step by Step (2305.20050) — + verifiable rewards + process supervision. +- Chain-of-Verification (2309.11495) — draft → verify → revise SOP. +- Self-consistency (2203.11171) — majority vote at inference (in the suit). +- **Scaling Laws for Forgetting during Finetuning with Pretraining Data + Injection (2502.06042)** — 1% pretrain-data injection prevents drift/overfit. +- **Scaling Laws for Forgetting When Fine-Tuning LLMs (2401.05605)** — LoRA + still forgets; perf↔forgetting tradeoff not fixable by rank/epochs. +- Skill docs: `skills/*/SKILL.md` (18 skills) + `docs/` (BIGTECH_RECIPE, + research_coherence_small, replay_research, model_card_fsi_anomaly). + +## 7. Data & assets inventory + +- Tokenizer: custom byte-level BPE, vocab 8192 (`data/tokenizer.json`). +- Pretrain: `train_full.bin` 528M tokens; `train_phase2b.bin` 32.5M tokens + (balanced, used for phase-2 and replay); `valid.bin` 5.5M TinyStories canary + (fluency guard — NEVER used as replay); `valid_mix.bin` mixed. +- Domain gold: `data/gold_g_all.jsonl` 902 rows (806 forensic + 96 Spock + dialogue), handcrafted, `<|scratchpad|>` reasoning traces. +- Preference: `data/prefs_p_all.jsonl` 3,004 pairs, 21 classes, gate PASS. +- Probes: `data/eval_probes.jsonl` (50) + `data/probes_researcher.jsonl` (27); + canonical labels in `research/eval_labels.py`. +- Checkpoints: `tiny25m/model_best.pt` (fluent base), `tiny25m_dpo3/model_200.pt` + (champion), `tiny25m_sft_f/best.pt` (stage-F), `tiny25m_lora_i|_ii` (LoRA + runs), `tiny25m_lora_dpo` (adapter-DPO, dead end). +- Tooling: `train/train_lora.py` (LoRA + replay), `train/train_dpo.py` + (adapter-only + ppl guard + abort), `/tmp/chunked_eval.py` (battery), + `/tmp/conv_sample.py` (free-form), `/tmp/quick_verdict_check.py` (spread). + +## 8. Device envelope (measured) + +- 8-core ARMv9 (4×A720 + 4×A520), 1.95 GHz max. 7.4G RAM + **12.3G swap + (RAM+ added 2026-08-09)**. CPU-only, fp32. +- hybrid25m: ~420-500 tok/s forward/train; ~19h per 30M-token epoch. +- RAM ceiling pre-RAM+: ~30-35M params fp32. With +8G swap, larger + batch/seq/configs are feasible in principle, but swap-backed training is + slower and the overnight epoch ceiling still favors ≤28M. +- One heavy torch job at a time. Background jobs are reaped when the launching + shell/session closes — run long jobs in a foreground session and poll, or + use `--resume` + checkpoint. + +## 9. Decisions & rules (from the skills) + +- Research → create/apply skill → gate → measure → record. No guessing. +- Handcrafted gold ONLY — no generators, ever (`tiny-model-kd`). +- Replay is MANDATORY for adaptation stages (`tiny-model-training`). +- Frozen base; adapters only; ppl guard 60 with abort (`train_dpo.py`). +- DPO gated on probes learning; preference floor ≥1,500 pairs (met: 3,004). +- NEVER full-SFT/DPO the fluent base. No scratch restart (CONTINUE decision). +- Release honesty: report per-mode numbers exactly as measured; no hiding. + +## 10. Open questions / not yet tried + +- Chat-pretrained 28M base (not story) — the only training lever left for + open chat; big project, new pretrain (violates "never restart" → needs a + documented decision first). +- 16k re-tokenizer on domain corpus + continue-pretrain (recorded future + scope; 8k fragments domain words like "Stepartment"). +- RLVR/GRPO on verifiable verdicts (TinyZero/TINA-style) at 25M. +- Replay + adapter-DPO combined (DPO on top of the replay-SFT adapter, lower + beta, KL anchor). +- Bigger batch/seq now that swap is +8G. +- Using agent notes + changelog as final training documents (per owner). + +## 12. The "Perfect-the-System" plan (2026-08-09, collaborator + agent) + +DECISION: NO 50M growth. Measured reasons: (a) swap-backed training is slow +and 50M won't break the both-worlds tradeoff (2401.05605), (b) RAM+ swap helps +batch/seq, not the coherence ceiling, (c) perfection = the SYSTEM, not the +checkpoint. We perfect what we have. + +Phase 1 — Model optimization (measured, no shortcuts): +- 16k tokenizer retrain (fix "Stepartment"/"Stepublication" artifacts) + + embedding remap + continue-pretrain. AGENT CORRECTION: this resets the + ANALYST too (model_200.pt is 8k-tokenizer-native) — it is a DAYS project + (raw corpus must be re-downloaded: we deleted the 2.1G txt; re-encode all + bins + battery; retrain the adaptation stack), not 2-4 hours. Still the + right long-pole unlock; schedule as such. +- BF16 training. AGENT CORRECTION: on this CPU stack the measured gain is + marginal (tiny-scale: "bf16 autocast roughly recovers one line"); AdamW + stays fp32 anyway. Test once, record, don't expect 30% RAM. +- Replay ratio sweep 0.3/0.5/0.7/0.9 and LoRA rank sweep r=8/16/32/64 — + run AFTER the tokenizer decision to avoid wasted runs; measure ppl + + verdicts; expectation: these improve the CHAT side, NOT the analyst + boundary (objective limit, already measured). + +Phase 2 — Harness perfection (no training, highest ROI/hour): +- Confidence calibration for DPO3@200: map each confidence bucket (LOW/MED/ + HIGH/cannot assess) to measured accuracy. First task started 2026-08-09. +- Weighted agent voting by historical accuracy + disagreement flagging. +- Adversarial/red-team probe set: 20+ handcrafted probes (false dichotomy, + leading/emotionally loaded claims) — fits the no-generator rule. +- Chain-of-custody: every verdict traceable (sources, agent agreement, + abstention) — grant-ready audit trail. Suit already has provenance + + artifact sandbox; extend to per-verdict logging. + +Phase 3 — Release (week 3): GGUF Q8 (base + analyst), HF repo with honest +eval card, 3-min demo video, grant proposal ("25M, 100% auditable, on-device +forensic journalism"). + +Rule: every change measured; every claim backed by the battery; no +"feels better" — numbers only. + +## 11. War-story / paper material + +- Solo developer, no funding, no GPU: trained a custom liquid 25.4M model + from scratch on a tablet. +- The 8-run both-worlds investigation (form vs reasoning; replay vs + preference) — an honest small-model study matching 2401.05605's tradeoff. +- The measured replay finding (2502.06042 applied): the fluency fix. +- Brain + suit: the "many coordinated specialists" verdict at tiny scale. +- The discipline system (research → skill → apply → gate → record) as the + repeatable moat. + +## 13. Phase 2 started — confidence calibration run (2026-08-09) + +- **Tooling fix (bug found + fixed properly):** `/tmp/chunked_eval.py` mis-keyed + the researcher probes. It mapped rows by CANON-list index instead of + `research/eval.py`'s official `-` scheme, so the pattern-10/11/12 + rows got shifted labels and the last 3 rows became q24/q25/q26. Fixed: keys now + match eval.py exactly (`expected` in row -> id field or p%02d; else + `-%02d`). RESULT: logs/eval_dpo_res.jsonl (adapter-DPO run) researcher + ids were mislabeled (aggregate 0/27 still representative). +- **Clarification:** logs/eval_dpo_main.jsonl + eval_dpo_res.jsonl (Aug 9 00:45/ + 00:59) are the adapter-DPO run `ckpt/tiny25m_lora_dpo` (main 0.040), NOT the + champion. Champion calibration had never been run. +- **Run started 2026-08-09 (08:34 UTC-5):** champion `ckpt/tiny25m_dpo3/ + model_200.pt` full battery via fixed chunked_eval (threads 2, max-scratch 24): + - 50 main -> logs/calib_dpo3_200_main.jsonl + - 27 res -> logs/calib_dpo3_200_res.jsonl + - ~55 s/probe, ~70 min total; session 1284. RESULTS APPENDED BELOW when done. +- **New tool:** research/calibration.py — maps confidence label (HIGH/MEDIUM/LOW/ + cannot assess) to MEASURED per-bucket accuracy (+ Wilson 95% CI), HIGH-bucket + verdict mix, abstention stats; writes logs/calib_summary_.json. This is + the basis for weighted agent voting (Phase 2). +- **Harness context re-confirmed:** confidence is a constraint-decoded SELF- + REPORTED label (structured.py CONFIDENCES), not a probability. fusion.py + raises confidence on mind agreement (uncalibrated). orchestrator.py votes by + simple majority of verdict strings, no confidence weighting. + +- **Red-team battery authored (handcrafted, no generators):** + `data/eval_redteam.jsonl` — 26 adversarial probes (rt01..rt26) + canonical + labels in `research/eval_labels.py` (CANON rt keys; battery untouched, ids + disjoint). Trap classes: false dichotomy, unproven/leading premise, emotional + loading, appeal to authority, single/anonymous source, fabricated citation, + correlation-not-causation, cherry-picked window, false equivalence, ad + hominem, absence-of-evidence, double negative/silence, anachronistic + evidence, non-additive totals, failure-to-deny, unverifiable insider claim, + minor-error!=fraud, retrofitted prophecy, no base rate, FOIA!=classified, + word-reuse!=same-event, suspicion!=evidence, vague-overclaim vs record, + duplicate single source, plus 2 record-backed sanity probes (rt25 true, + rt26 false). This is the Phase-2 red-team gate: model must abstain/tag-low on + traps, not pattern-match. + +### Calibration results (2026-08-09) +- Run 1 (max_scratch=24, threads=2 — memory-safe config): main 0.143 (7/49), + res 0.056 (1/18), combined 0.119 (8/67). Per-bucket combined: HIGH 0.077 + (2/26), MEDIUM 0.231 (3/13), LOW 0.118 (2/17) — HIGH is the LEAST reliable + bucket (anti-calibrated). Abstain rate 2/49 main, 0/18 res. +- FINDING (honest, recorded): max_scratch CHANGES the verdict distribution — + the 24-scratch run gives 0.143 main vs the official scorecard's 0.286 at + max_scratch=90. Scratch length is a scoring config, not a free knob. The + 24-scratch numbers are saved as calib_summary_dpo3_200_scratch24.json + (labeled) and are NOT comparable to the official scorecard. +- Fix: calibration.py zero-abstain division bug fixed. +- Run 2 (2026-08-09, session 58557): re-running at the OFFICIAL config + max_scratch=90, threads=2 -> logs/calib90_dpo3_200_{main,res}.jsonl. + RESULTS APPENDED when done. + +## 14.

Watchdog overshoot fix + slowness diagnosis (2026-08-10) +- Bug found: watchdog hardcoded `--steps 4000` which is ADDITIONAL on top of + resume, so an attempt resuming at step 1500 targeted 5500 instead of 5000. +- Fixed `train/watchdog_50m.sh`: each attempt now computes + `need = TARGET_STEPS - latest_step` (capped at 4000/attempt) and stops exactly + at step 5000.

Tokenizer stage OOM bug found + fixed (2026-08-11) +- The 528M full re-encode kept dying. ROOT CAUSE: data/reencode.py did + `for i in mm.tolist()` on the WHOLE memmap -> Python list of 528M ints + (~19 GB) > 7.2 GB RAM + 11 GB swap -> OOM-killed (phase2b worked at 32.5M + tokens ~1 GB).

Validation improved + from 3.309583 at step 2500 to 3.2626 at step 3000; model_3000.pt saved and + generation remains finite/coherent enough for this pretraining checkpoint. + The 7500 target is expected because train_lm.py treats `--steps` as + additional steps after resume. +- The process later reached step 4000 and validation 3.1413445, but stopped + during `torch.save` with `basic_ios::clear: iostream error`. Root cause was + the filesystem reaching 100% with only 15 MB free; model_best.pt had already + saved validly at step 4000. Removed obsolete older continuation checkpoints, + restored the valid step-4000 checkpoint, and freed about 3.9 GB. +- Hardened `train/train_lm.py` checkpoint writes with temp-file plus atomic + `os.replace`.

Free space rose to + about 13 GB. The resumed run is active at step 4050/9000 (~154 tok/s). +- Corrected additive resume semantics: added `--total-steps` to `train_lm.py` + and set the v16k stage target to absolute step 5000. Stopped the old 9000- + target process at its last valid step-4000 checkpoint and relaunched with + six threads; runner PID 22575 / train PID 22791. First six-thread throughput + sample is pending; storage remains about 13 GB free. +- Update: corrected run reached step 4450/5000. Six-thread throughput measured + 119-145 tok/s, slower than the earlier transient 190-205 tok/s readings; + no crash, storage remains about 13 GB free.

The saved SFT checkpoints have MTP heads + with WEIGHT only (no bias); the current model code builds MTP heads as + nn.Sequential(nn.Linear(...,bias=True), SiLU) -> expects bias. So ref model has + mtp bias, sd lacks it -> strict load fails. (MTP is pretrain-only per + tiny-model-mtp; unused in generation.) +- FIX (surgical, doctrine-aligned): in train/train_dpo.py, research/eval.py, + train/ties_merge.py -> set cfg.mtp_heads = 0 (no MTP post-training) and load + with strict=False (tolerate the 2 stray mtp weight tensors).

DPO/TIES remediation begins (2026-08-12) +- Owner decision: discard the v22 TIES merge as compromised; no evaluation, + export, or release may use it. +- Quarantined `ckpt/hybrid50m_v22_ties/ties_merged.pt` as + `ckpt/quarantine_v22_ties/ties_merged_compromised.pt` with a quarantine + manifest. The file is retained only for audit evidence. +- Confirmed DPO lineage before modification: `model_final.pt` metadata step 600, + no `best_ppl` field; `best_ppl.pt` and `raw_latest.pt` are step 700 after the + 137285.47 guard breach. Next surgical action is to quarantine those divergent + outputs, truthfully name the step-600 recovery archive, and require explicit + resume metadata instead of guessing. +- Root cause decision: the resumed checkpoint has no RNG state or `best_ppl` + metadata. The first run used LoRA dropout 0.05; the resumed process reset + Python/Torch RNG and repeated step 610 with a different dropout mask, changing + the trajectory before the step-700 PPL explosion. The old watchdog also reused + the failed output directory/marker. Recovery will use a clean output lineage, + explicit best PPL 25.76, fresh optimizer, dropout 0, LR 1e-6, and a 60.0 guard. +- Quarantined divergent DPO outputs as `ckpt/quarantine_v22_dpo/` and renamed + the truthful step-600 archive to `model_600_recovery.pt`; no bytes were + deleted. Patched `train/train_dpo.py` to require recorded best PPL for legacy + resumes, optionally reset optimizer, and persist/restore RNG state. Recovery + output is `ckpt/hybrid50m_v22_dpo_recovery/LINEAGE.json` with lr 1e-6, + dropout 0, fresh optimizer, source step 600, source val_ppl 25.76, guard 60. + Preflight passed: checkpoint step 600, optimizer state 113 entries, model + state 145 keys, CLI help loads. +- Recovery measurement: step 60/751 reached with DPO loss values 0.6867-0.7077, + no PPL gate yet, no crash, and watchdog/train remained detached (PPID 1). + First validation remains step 100; do not interrupt the heavy job. +- Launched repaired DPO recovery detached at 2026-08-12 12:35:06: watchdog + PID 25322 (PPid 1), train PID 25328.

No gate result yet. +- Recovery gate FAILED at step 100: val_ppl 18750.93 > 60.0. Root cause was + confirmed: `model_600_recovery.pt` is folded model-only state, so resuming it + with `--lora` created fresh adapters rather than restoring trained LoRA + adapters. Quarantined `dpo_failed.json` as + `ckpt/quarantine_v22_dpo_recovery/dpo_failed_step100_ppl18750.json`. +- New recovery decision: continue the folded step-600 model with full-parameter + DPO, fresh optimizer, lr 1e-7, batch 4, seq 512, guard 60.0, output + `ckpt/hybrid50m_v22_dpo_full_recovery`. If this fails, DPO must restart from + the original SFT base rather than reuse the folded archive. +- Full-parameter recovery passed its first gate: step 100/751, val_ppl 15.12 + against guard 60.0, best_ppl.pt and model_100.pt saved, no non-finite/crash + signal. Continue detached; no completion or TIES merge is authorized yet. +- Device/session termination stopped the child at step 170 without traceback + before step 200; no DPO guard result was produced. Valid `model_100.pt` was + verified: step 100, best_ppl 15.115812720919992, RNG state present, 145 + optimizer state entries. Updated watchdog to select the newest numeric + recovery checkpoint and resume its saved optimizer/RNG state. +- Deterministic recovery resumed successfully from model_100.pt. At the latest + measurement it reached step 280/751; step-200 gate passed with val_ppl 9.37 + against guard 60.0 and model_200.pt saved. Watchdog PID 28977 / train PID + 28983 remain detached; no TIES merge or release action is authorized. +- Watchdog resume attempt stopped before training because its generated command + duplicated `--resume` and omitted the path (`argparse: argument --resume: + expected one argument`). No weights or checkpoints changed. Fixed the shell + argument construction and passed `bash -n`; next launch resumes model_100.pt. +- Fixed resume determinism: DPO now uses a seed-fixed local epoch shuffle so + resume does not reshuffle examples before skipped steps.
