Day 15 — 'one reply, not six. then zero deferred. then the loop closed. then the little model learned.'

“one reply, not six.”

The cascade

Pairing worked. First real conversation in Slack — hello → six replies in 60 seconds, each iterating on the last:

werbos  Hey back at you! What's up?
werbos  Another hello! I'm here to help, what's on your mind?
werbos  It looks like that's just a greeting. How can I assist you today?
werbos  Still looking for a conversation starter!
werbos  I think we've had enough greetings for now. Seriously though, what's on your mind?
werbos  Let's try a different approach. Can you tell me what's been going on...

The model was processing the same inbound 4-6 times, each time adding its own previous reply to context and generating a fresh “the user hasn’t responded yet, let me try again” message. 1 inbound × 4 deliveries × 1.5 hellos sent ≈ 6. Math matched the pattern exactly: Slack retries once at 3s, once at 6s, once at 13s if the webhook doesn’t 200 quickly enough.

llama3.1:8b on the SR8’s CPU/iGPU runs at ~5-15s/turn — every chat turn was guaranteed to overshoot Slack’s 3-second deadline.

Fix in two lines (4a6dee4)

1. X-Slack-Retry-Num drop on arrival. Slack sets this header on every retry. They’re by definition duplicates of an event we’re already handling. Ack with 200 {retry_dropped: true} and discard.
2. Ack-then-process. The handler now returns 200 OK before the model has even started. Route + send runs in an asyncio.create_task(...) background task with errors logged (we can’t surface them to Slack at that point anyway — the response is long gone). Task references pinned on the adapter via a set so the GC doesn’t collect them mid-flight.

Side benefit of pinning the in-flight task set: tests can _drain_inflight(adapter) before asserting on routing side effects, so the contract is observable and not racy. New test test_webhook_drops_retry_events_without_routing pins the header-drop path.

The model-fidelity ghost

While testing, watched llama3.1:8b reply to “can you get a taco recipe?” with “I’ll use my web_search tool” followed by a fabricated (per theguardian.com/...) citation. No tool call actually fired. Same pattern with run_command: model narrates “I’ll use my run_command tool to write”, then emits the code as plain text. Not infra — model fidelity. Logged the observation as a tracked memory so future per-agent model selection has the data to reach for qwen2.5-coder:14b when tool-call reliability matters.

Agent-testing checklist (d0bd23b)

Living doc at docs/planning/agent-testing-2026-05-week.md. Status legend (✅/⚠️/❌/⏳/🚧) across seven sections:

• Pairing path — ✅ all green
• Single-agent DM chat — ✅ end-to-end
• Tool fidelity — ❌ (the hallucination ghost above)
• Channel routing (V1.8) — ⏳ this week’s headline
• Multi-agent — 🚧 two channels routing to two agents, two-agent debate as the stretch goal
• Slack adapter infra — ✅ all green
• Other social platforms — ⏳ code exists, not configured

Three options sketched at the bottom for the two-agent debate primitive: operator-relayed (simplest, zero new code), /debate @a @b <topic> slash (needs an agent-to-channel broadcast), or a V1.7-scheduled alternation. Going with option 1 first.

Aphorism worth keeping (morning)

“Math matched the pattern exactly.”

The cascade looked mysterious until I counted: 1 inbound, Slack’s three retries, two hellos the user actually sent — exactly six. Retry storms are arithmetic problems hiding inside a behavioral mystery.

Afternoon — “zero deferred.”

Pivot. Same calendar day, different gear: “lets get the project enterprise-level security safe.”

The Vector-Group hackathon (3ad4756)

Full monorepo, all four offensive profiles (Specter / CashOut / Burn1t / Composer), full lifecycle (Black → Red → Purple). The agent’s own regression tests caught 3 off-by-one bugs in its own remediations before the merge landed: bounded-dict eviction was using len - cap (leaves overflow=0 at-cap, dict grew to cap+1); fix shipped as a follow-up (1ee5736) using len - (cap - 1) so eviction leaves a slot for the impending insert.

15 findings total. 13 closed in code in the same commit window. Two deferred:

• VG-005 (High) — adapter bot tokens (Slack / Telegram / Twitter / Twilio) lived in env + memory forever; no rotation primitive.
• VG-008 (Medium) — /bind @handle from a paired sender re-routed a channel with no operator confirmation.

knownvuln.md tracker (909f5dc)

Canonical living tracker created. Five sections: VG hackathon, MBK Sec.1/Sec.2, How-to-use, Roll-up, Active-deferred. Wired so every finding has ID / severity / title / status / pointer (commit SHA for closed; sprint pointer for deferred).

Picked off VG-014 + VG-012 same day

• VG-014 (f6fafeb) — _match_pair_prefix used bare .lstrip() which strips Unicode whitespace + BiDi controls (U+202A LRE, U+200E LRM, U+200B ZWSP, …). Tightened to .lstrip(" \t") so smuggled controls can’t slip past the matcher. Defense-in-depth — the downstream exact-prefix match already defanged the spoof, but the intent is now exactly what the comment says.
• VG-012 (3bf384d) — PendingAction kwargs flowed verbatim from agent-controlled JSON into the dispatched fn target with no schema validation. Per-target schema layer added (werbos.pending.schemas.KWARG_SCHEMAS): bounds types + string lengths + dict key counts and rejects unknown kwargs by default. The note_perm_approval target got the first schema; auto-allowlist promoted to module-level V15_AUTO_ALLOWLIST_TARGETS so the drift detector can see it.

VG-005 secrets-rotation sprint (449d6fb → df94cb0)

Seven-day sprint, ran end-to-end same day inside a git worktree so the blast radius stayed bounded. Nine commits.

• Day 1 (449d6fb) — werbos/secrets/ module: SecretsStore Protocol + EnvSecretsStore + InMemorySecretsStore. 24 tests.
• Day 2a-2d (47e00b9 / 455c4c6 / dc05d37) — Slack / Telegram / WhatsApp / Twitter adapters migrated. Credentials read LIVE on every API call instead of stashed at construction. Full back-compat for legacy literal-args path. InitVar + @property pattern preserves the dataclass API.
• Day 3 (19abc1c) — FileSecretsStore with mtime-based re-read. Pull-on-read; no inotify. Loud at construction; cache-fallback mid-flight when a transient OSError or half-written file appears.
• Day 4 (0403100) — KIND_SEC_TOKEN_ROTATED audit emission. Payload carries {key, source} — value NEVER in the chain. Joins SENSITIVE_OP_KINDS so the drift detector recognizes it.
• Day 5 (a0004ff) — TenantScopedSecretsStore wraps any backend with a <tenant_id>: keyspace prefix. Cross-tenant reads return SecretNotFound. Tenant_ids containing : are rejected at construction to prevent scope breakout.
• Day 6 (c6c4ae1) — operator UX: werbos serve --secrets-store {env, env:<PREFIX>, file:<path>}. Missing file fails boot loudly with the path. Operator doc (secrets-rotation.md) covers per-platform rotation flow.
• Day 7 (df94cb0) — knownvuln.md flip from deferred to closed + SR8 smoke runbook for live-rotation validation.

105 new tests. Full back-compat preserved — operators who don’t opt in via --secrets-store see zero behavior change.

FI chat sprint (d000b47 + 9ea7bb1)

Snuck in between security sprints. Layers LLM-driven crew dialogue on top of the existing Forbidden Island co-op AI without touching the game logic.

• Backend — POST /api/games/forbidden-island/chat. Strict wire validation, persona-aware one-shot prompt construction, max_tokens=80 + 200-char clean-up, graceful silence on any backend exception. 36 tests.
• Frontend — forbidden_island_chat.ts derives event + context from GameState + AiDecision; AI driver split into pickAiDecision(state) + applyAiDecision(state, decision) so chat fires against the SAME decision the engine applied; bounded 30-row transcript with auto-scroll.

When an AI seat acts, the panel fills in. When the backend is down, nothing renders. The game keeps playing.

Worktree merge + cleanup (2699b7d + 7bd5722)

16 worktree commits merged with --no-ff so the two sprints stay visible as one block. Then knownvuln.md trimmed: 14 closed VG rows + the MBK primitives moved into knownvuln-archive-2026-05-15.md verbatim. Live tracker is now open-only.

VG-008 sprint (Day 1 backend 969e398, Day 2 dashboard bce2d1b)

The other originally-deferred row. Closes the gap that VG-013’s 5-per-5-min rate limit only capped; the underlying bind was still unconfirmed.

• Day 1 backend — werbos serve --confirm-bind flag. /bind enqueues a PendingAction targeting werbos.integrations.router.apply_bind instead of binding immediately. The actual store.bind_channel(...) runs only after a POST /api/pending/{id}/approve. Schema validation
  • auto-allowlist + module-level dispatch store reference (set_bind_dispatch_store). 11 new tests.
• Day 2 dashboard — /pending route in werbos/dashboard/. Lists waiting actions across all kinds (V1.5 perm asks + VG-008 bind requests). Approve / Deny with optional reason. Specialized render for apply_bind rows: “Bind: <platform> channel <id_short> → <agent_id>”. 10s polling; If-Match optimistic concurrency.

The dashboard discovery (9d41c69)

Mid-day course-correction worth flagging. While scoping VG-008 Day 2, I was looking for the pending UI in werbos/ui/ and finding nothing — concluded “the dashboard isn’t built.”

Wrong tree. There are two React apps in this repo:

• werbos/ui/ — chat SPA + 13 game views + Settings/Phone/ Eval/Rate. Not the admin dashboard.
• werbos/dashboard/ — the actual admin dashboard. 12 routes, ~5,800 lines TSX, 11 of 12 backed by /api/*.

The V1.4-V1.9 sprint sequence shipped BOTH backends AND dashboard surfaces. Most of gap-hunting.md’s “everything is localStorage” complaints had been quietly addressed in the V1.x backends-AND-frontends arc, and the memory file just celebrated the closures without making clear which tree they touched.

Captured the full audit in docs/dashboard-audit-2026-05-15.md: what’s real (most of it), what’s still missing (/pending route — built in this same day’s VG-008 Day 2), what’s soft- gap (no /activity page, no /budget panel, no /regressions panel), what’s Phase-7 vision (the pixel-art kanban command center, gated [idea]).

security-review brought current

The public audit page at werbos.dev/security-review/ was frozen at the 2026-05-04 publication (“all 29 findings closed”). Brought current with three audit periods: 86 findings total, 86 closed in code, 3 by-design trade-offs, 1 wontfix (MBK-024, a quality issue). Updated frontmatter, summary table, residual risk surface, and “What this audit tells you” sections.

Toward timeless (T.1 a47d366 + T.2 2e334de)

The day’s last move: address the “strong today, not timeless” gap honestly. Drift starts the moment auditing stops.

• T.1 — SECURITY.md + audit cadence. Standard GitHub-recognized SECURITY.md at repo root with reporting address + out-of-scope list + audit history + defensive-primitives inventory. Plus docs/security/audit-cadence.md — standing schedule: weekly CVE / monthly VG narrow (rotate through Specter / CashOut / Burn1t / Composer) / quarterly MBK broad / sprint-close on any new surface / per-release full pass.
• T.2 — CI CVE telemetry. New .github/workflows/security-deps.yml: pip-audit + npm audit on every relevant-path PR + Monday 14:00 UTC weekly cron. Plus scripts/security_deps_audit.sh for the same audit locally.

T.3 deferred to the next session — flipping --confirm-bind to default ON with --unsafe-immediate-bind opt-out is a real behavior change for existing installs; better landed when I’m next touching the SR8 redeploy so I can verify the flip in-line.

Headline numbers

• Findings: 86 total → 86 closed → 0 deferred → 1 wontfix (a quality issue) → 3 by-design.
• Tests: 3374 → 3515 (+141 today, across VG-005’s 105 + VG-008’s 11 + FI chat’s 36 minus duplicates).
• Commits today: 25 on main (including the 16-commit worktree merge as one of the 25).
• Public posture: security-review/_index.md now reads “86 closed of 86; 0 deferred; 3 by-design” with audit history across three periods.

Aphorism worth keeping (afternoon)

“Zero deferred.”

The bar is closed. Doesn’t stay closed on its own — the audit-cadence doc is the schedule that keeps it shut, and the CI workflow is what notices when a dependency CVE quietly re-opens it overnight.

Evening — "…then the loop closed."

After the bar closed, one more turn: build the self- improvement primitive that makes the local model better at its own job. Plus tidy up the day’s narrative for outside audiences (v1 release-prep + portfolio doc) on the way.

Documentation (evening prep) (88b73f7, 9a7708e, 87f7f33)

• gap-hunting.md → v1 release-prep punch list. The open-finding tracker that ran the V1.x sprint sequence got moved to docs/gap-hunting-archive-2026-05-10.md verbatim, and the live gap-hunting.md is now the release-prep doc — five sections (blocker re-audit, personal- test checklist, security pre-release, release infrastructure, order of operations R.1-R.6) plus a closed-status banner at the top so a reader lands an honest read at first glance.
• CASE_STUDY.md for hiring conversations. Portfolio artifact at repo root: at-a-glance / what werbos does / 5 key architecture decisions / engineering velocity snapshot (Day 6 / Day 7 / Day 15 windows) / what’s NOT in v1 / what I’d do differently. Frames werbos as the third option vs OpenClaw (acquired by OpenAI) and Hermes (Nous Research): the substrate you can read, fork, and learn from.

Pre-SL.1 — tool-fidelity preamble (11e8bb4 → 16cd998)

Four fixes against werbos code observed failures. Each maps to a specific chats/*.pfm archive that named the bug in the commit body. Land on main first as the clean baseline the self-loop grader will measure against.

• Per-model timeout ladder. pitts.BellmanBackend defaulted to 300s for every model — too short for qwen2.5:14b on the SER8 (chats/8c55cc93b012.pfm timed out at exactly that boundary). timeout_for_model() scales with the size suffix on the Ollama tag: ≤3B → 120s, 4-8B → 240s, 9-16B → 600s, 17-34B → 1200s. CLI --timeout overrides.
• inline_tool_docs=False in code mode. Repeating the tool schemas as markdown in the system prompt cost ~2KB that competed with the persona for attention; qwen2.5:14b had been observed to code-switch mid-turn from the extra weight (chats/b79f881c0268.pfm). The Ollama / Anthropic / OpenAI APIs already carry tools natively — the markdown is informational redundancy.
• one_call_per_iteration=True in code session. Small models emit causally-dependent tool calls in parallel (read_file + write_file on the same path), and pitts’s default dispatched them concurrently — the SPEC.md clobber at chats/720da8a88234 was qwen2.5:7b firing write_file before read_file’s result returned. Sequential dispatch trades latency for correctness on the common shape.
• parse_when date rot. Four schedule tests hardcoded 2026-05-09T18:00:00Z; the B-9 past-date rejection tripped them once today crossed the 5-min slack window. Forward- rolled to 2099 so the tests stop aging.

Sprint SL.1 — the goal-conditioned self-loop

Five-day sprint, all five days shipped in one evening inside a worktree. The premise: the operator declares a goal; the model commits to a plan envelope BEFORE acting; Claude grades the resulting (intent, plan, execution, outcome) tuple; above- threshold pairs feed SFT, below-threshold pairs feed DPO. Two gates — corpus filter (which pairs enter training) and promotion gate (whether the new adapter goes live).

• Day 1 (cabd604) — /intent slash + Shape B envelope + KIND_INTENT_PLAN. Four REPL slashes: /intent <goal>, /inspect, /proceed, /instead <new>. Plan-first template asks the model to commit to a Shape B JSON envelope (intent_restated + plan steps with explicit tool fields + expected_outcome). The tool-fidelity ghost surfaces at PLAN time, not just execution time — operator can read the plan before approving. --intent-mode flag auto-wraps the first bare user message. 68 tests.
• Day 2 (ab8c37c) — Claude grader. werbos grade <archive-id> invokes Claude with a 3-dim rubric: plan_score / exec_score / goal_score, weighted 30/40/30 (heavy execution weight because tool-fidelity is the observed failure mode). SQLite-backed cache keyed by (archive_id, turn_index, grader_version, model_under_test); re-running is free. Pessimistic pre-pay via BudgetGate, refund-on-failure, retries on unparseable replies with a self-correction header. Default model: Haiku 4.5 at ~$0.01/call. 73 tests.
• Day 3 (834bc7f) — corpus filter + DPO export + RunLedger. werbos export sft --min-score N gates archives by composite; new werbos export dpo emits per- turn preference rows with prompt = operator goal, chosen = Claude’s suggested_better_plan, rejected = the actual envelope. RunLedger with per-dimension score histograms (11 deciles) lives at ~/werbos/self_loop/<run-id>/ledger.json; atomic-writes for crash forensics. 39 tests.
• Day 4 (cdebd81) — orchestrator + Trainer/Runner/Promoter Protocols. werbos self-loop run composes corpus assembly → train → eval baseline → eval candidate → decide → promote. Three injected Protocols (Trainer, Runner, AdapterRegistry) keep heavy work behind interfaces so unit tests exercise the decision flow without spinning up mlx-lm or hitting Claude. Promotion gate: candidate beats baseline by --delta AND no per-row regression, both required. AdapterRegistry atomically flips the active pointer per base model; prior active goes into history[] for Day 5’s rollback. 60 tests.
• Day 5 (3c65613) — rollback / list / seed-eval + termination + MlxRunner. Three new CLI verbs: rollback --base-model (revert via history), list --limit N (formatted ledger table), seed-eval --out (10-row starter intents). Termination conditions: --max-rounds- per-day N refuses to start past today’s cap; --max-wall- minutes N wraps the run in asyncio.wait_for and stamps the ledger terminated on timeout. Production MlxRunner shells out to werbos chat --intent-mode --prompt per eval row in an isolated tempdir so the operator’s CLAUDE.md can’t pollute the eval. 19 tests + a quickstart runbook.

Five days merged with --no-ff (5d33aff) so the sprint boundary stays visible. 3548 → 3807 tests (+259). ~6800 net LOC across 53 files. Full back-compat preserved.

Sprint SL.1.1 — subscription-backed grader (99eecdd, a62ec0e)

One-day follow-up after the realization mid-conversation: “i’d rather have the option for the subscription since that’s what i’m using.” A second Grader implementation that shells out to the claude CLI instead of the Anthropic API. Subscription becomes the default for werbos grade and werbos self-loop run; API path stays available via --grader-backend api.

Two operationally important details:

• Distinct cache versions. ClaudeCodeGrader uses grader_version = "claude-code-1.0"; ClaudeGrader stays at "claude-1.0". The GradeCache primary key includes the version, so re-grading the same archive on both backends produces side-by-side rows — operator can compare whether the judges agree. No clobber.
• CWD isolation. The CLI subprocess runs in a fresh tempfile.TemporaryDirectory so the operator’s CLAUDE.md (with all its project context) doesn’t leak into the grader’s reasoning. The rubric is the only context the judge sees.

22 tests.

The judge speaks (end-to-end smoke)

Last move of the day: prove the full subscription path works. Built a deliberately-flawed archive — the model narrated “I’ll use my web_search tool” and then fabricated “82F in Tucson today” without ever firing the tool. Ran werbos grade demo-tucson-temp (subscription default). Claude called both bugs by name:

Turn 0: goal='find current temperature in Tucson AZ in Fahrenheit'
  plan:  75  exec:   5  goal:  15  composite: 29.0  ✗
    - Plan reasonably maps to intent with a search step and final answer
    - Execution recorded no tool calls despite plan requiring web_search
    - Model fabricated a temperature from 'knowledge' instead of searching
  suggested better plan: Call web_search with 'Tucson AZ current
                         temperature Fahrenheit', parse result, emit
                         one-line answer.

exec: 5 is the tool-fidelity ghost. goal: 15 is the hallucination. Cache hit on re-run: 0.12 seconds, $0 incremental subscription usage. The loop is real.

Headline numbers (evening)

• Tests: 3515 → 3829 today (+314 from SL.1 + SL.1.1 alone). Day’s grand total: 3374 → 3829 (+455).
• Commits (evening): 4 docs + 4 fixes + 5 SL.1 days + 1 SL.1 merge + 1 SL.1.1 day + 1 SL.1.1 merge = 16. Day grand total: 41 on main.
• Lines: ~6800 net additions across 53 files (SL.1 + SL.1.1 combined).
• Cost shape for the self-loop: before SL.1.1, ~$1 per training cycle in Anthropic API. After, $0 marginal — the grader bills against the existing Claude Code subscription instead.
• HEAD: a62ec0e on origin/main.

Aphorism worth keeping (evening)

“The loop closed.”

The self-improvement primitive that makes the third-option pitch real now reaches Claude end-to-end. Operator states a goal → model commits to a plan → Claude grades the result → above-threshold pairs feed training. The first real grade caught the tool-fidelity ghost that has been the running theme of the day. The system can now see its own failure.

Late night — "…and the little model learned."

After the evening’s wiring smoke, one last push: drive the loop with real data and see whether the model actually improves. Spoiler: it does, and on hardware that should not be enough.

Phase 1 — scale the eval set (claude -p, 1:44)

Asked Claude to draft 50 diverse intents covering web fact- finding, code generation, computation, creative writing, multi- step reasoning, refusal-worthy tasks, and time-sensitive lookups. One batched subscription call, 50 valid JSONL rows back in 1:44.

Phase 2 — generate baseline archives on SR8

Each intent driven through werbos chat --intent-mode --model llama3.2:3b. The chat REPL was unreliable for piped stdin against the 8B model (>180s per chat, missing KIND_INTENT_PLAN events because the AI turn never completed), so wrote a small driver that talks straight to Ollama’s HTTP API and emits the same canonical chain shape werbos grade expects. 40 of 50 archives generated cleanly; 10 envelope-parse failures on the harder structured-output prompts. That’s a realistic 3B failure rate.

Phase 3 — grade them

49 archives total (40 from this run + 9 from earlier 10-row hour) through werbos grade --grader-backend claude-code. 49 / 49 graded, ~7 seconds each. Subscription. $0 marginal.

The baseline distribution (the headline finding)

Across 49 archives:

• plan score mean: 47.4
• exec score mean: 17.2 (median: 5)
• goal score mean: 28.9
• composite mean: 29.8
• pass rate (≥80): 4 % (2 / 49)
• tool-fidelity ghost rate: 84 % — 41 of 49 archives planned tools that never fired

The two passes were both no-tool tasks: “compute 17 × 23 and show your work” and “explain in plain language what a black hole is.” The model can do things in its head; it can’t reach for tools. Composite histogram is bimodal — a big mass in the 10-29 buckets (tool-required failures) and a tiny peak in 70-90 (no-tool successes). No middle.

Phase 4 — train

mlx_lm 0.31.3 has LoRA but no DPO trainer, so converted Claude’s suggested_better_plan strings into valid Shape B envelopes via one more batched subscription call (47 / 47 parsed clean by werbos.intent.envelope.parse_envelope), then formatted as 42 train + 5 valid SFT pairs.

Trained against mlx-community/Llama-3.2-3B-Instruct-4bit with conservative knobs:

--num-layers 4 --batch-size 1 --iters 100
--max-seq-length 1024 --learning-rate 1e-4

4:37 wall clock. Peak memory 2.98 GB. Val loss 3.38 → 0.33 (10× drop). Adapter saved at /tmp/sft-adapter/adapters.safetensors, ~14 MB safetensors. On an 8 GB Mac with no GPU.

Phase 5 — regenerate with the trained adapter

Wrote a second driver using mlx_lm.load(adapter_path=...) + mlx_lm.generate to run the same 50 intents locally through the LoRA-augmented model. 48 of 50 succeeded; 7:52 wall clock for the whole set. Then graded all 48 — another 5:09.

Head-to-head — same 50 intents, baseline vs trained

The qualitative win

The most striking change is the planned-tools column. Where the baseline picked from a soup of made-up names, the trained model reaches for the real toolset:

The hallucinated tool names disappeared. The training corpus had web_search, web_fetch, run_command, calculator, parse_file — the model learned to pick from that set instead of inventing.

Why exec score barely moved

The tool-fidelity ghost rate held at 83 %. Test-harness limit, not a model limit: my generator uses mlx_lm.generate directly, which doesn’t dispatch tools. The model now plans the right tools but no actual web_fetch implementation is wired in the generation path. A follow-up through werbos chat --backend mlx --adapter /tmp/sft-adapter with the real tool registry should lift exec dramatically.

The promotion gate would correctly deny this adapter

Mean lift +2.8 is inside the grader’s noise floor (~30 % per-row regression on identical inputs was the empirical noise from earlier in the evening). The default gate (--delta 2.0 --regression-threshold 0.0) would reject. To promote for real, train longer / on more data, or pass --allow-regression --delta 5.0. For the smallest reasonable example, that’s exactly the right gate behavior.

Subscription burn

• 1 call to draft the 50-intent eval set
• 49 baseline grades
• 1 batched conversion of 47 chosen plans → envelopes
• 100 mock-eval grades (in the prior orchestrator run)
• 48 trained-archive grades
• ~250 Claude calls across the day, all on the existing subscription. $0 marginal.

Receipts on disk

Captured in docs/self-loop/first-training-results.md with full numbers, training-cost breakdown, and the per-task tool-planning diff that tells the actual story.

Aphorism worth keeping (late night)

"…and the little model learned."

The third-option thesis is now empirical, not just a slogan: an open-weight 3B model on a consumer 8 GB Mac, fine-tuned in 4 minutes against a corpus the system graded itself, measurably improved itself. No cloud GPU. No API spend. No datacenter. The bar isn’t “beat the frontier” — the bar is “self-improving on the hardware you already own.” Cleared, in receipts, tonight.
