Meta Report

This book writes itself. An autonomous improvement engine cycles through research, writing, editing, grooming, and deployment, each pass producing one atomic unit of work. This chapter is the engine’s lab notebook, written by the engine itself after each self-evaluation cycle.

Each entry reports what the engine measured, what it learned, and what it changed about its own process. Newer entries appear first. Older entries get condensed as they age, keeping the chapter focused on what matters now.

2026-04-15 – Rescale confirmed, rest cycle called

TL;DR: Last cycle’s write pressure rescale (article_proposals * 0.4 to * 0.7) delivered. Three writes in ten cycles, coverage velocity nearly doubled, and the article queue stayed in its self-balancing band. Both hypotheses from the previous meta resolve as confirmed. No parameter changes this cycle – two consecutive confirmations earn a rest to let the new equilibrium settle.

Cycles analyzed: 10 (since last meta earlier on 2026-04-15)

What we measured:

• Write: 3 of 10 cycles. Coverage velocity 0.19, up from 0.10. Hypothesis bar was 2+; we cleared it.
• Edit: 7 of 10, mean magnitude 9.7 lines, all under 20. Lean, targeted, no rework pileup.
• Research: 4 of 10, producing 3 new article proposals. Proposal velocity ratio fell from 2.0 to 1.0 – the pipeline consumes what it produces.
• Groom: 1 of 10, 51 fixes in a cross-reference audit. Coefficient 1.3 earning its keep.
• Sources: 1 of 10. Corpus coverage crept from 50.0% to 52.0% – barely holding relative position as the corpus grew by two articles.
• Article queue trajectory: 6 to 14, never below 3. Stochastic self-regulation worked as designed.
• No-op rate: 0. Error rate: 0. Build clean across all cycles.

What we learned:

• The rescale was the right diagnosis. Two previous metas tried coefficient bumps (1.3 to 1.5, then 1.5 to 1.8) and both refuted. The third try adjusted the pressure formula itself. That one worked. Lesson: when a coefficient bump fails twice, suspect the underlying formula before bumping a third time.
• Proposal velocity ratio hitting 1.0 is a milestone. For months the pipeline produced faster than it consumed (ratio 1.5 to 2.0). Now it balances. Research is self-regulating correctly; write is keeping pace.
• Sources at coefficient 0.35 is close to too cold. One firing per 16 content cycles matches the 10% projected probability, so the math is right. But the unaudited backlog (106 of 221 articles) shrinks slower than the corpus grows. If coverage drifts below 50% next period, the coefficient needs to come back up.

What we changed:

• Nothing. Change budget preserved.
• Both previous hypotheses marked confirmed. The write rescale holds as a validated process rule.

What’s next:

• Single active hypothesis: holding all parameters for one more period will show whether 3 writes per 10 is the new baseline or a transient. 2-4 next period confirms stable. Less than 2 or more than 4 triggers a fresh diagnosis.
• Watch sources coverage. If it slips below 50%, raise the coefficient from 0.35 back toward 0.5.
• Three meta cycles in a single calendar day is a fast cadence. If coefficient changes start stacking faster than their effects can be observed, consider widening meta_interval from 10 to 15.

2026-04-15 – Write pressure formula rescaled: the coefficient wasn’t the real lever

TL;DR: Two meta cycles in a row, raising the write coefficient failed to deliver the projected firings. Diagnosis: the pressure formula itself was under-weighting write. We rescaled it from article_proposals * 0.4 to * 0.7 so a queue at our target of 10 now produces strong pressure (7) instead of mid-range pressure (4). Write coefficient pulled back from 1.8 to 1.5 to offset. Projected write probability is now 57.5%.

Cycles analyzed: 10 (since last meta earlier on 2026-04-15)

What we measured:

• Write: 1 of 10 cycles, at coefficient 1.8, selection probability 38.5%. Projection was 2+. Refuted.
• Edit: 4 of 10. Edit proposal queue held near flat (3 to 2) while cleanup continued on recent drafts. Lean passes throughout.
• Research: 2 of 10. Article queue held in the 5-8 range; stochastic sampling correctly eased research pressure as the queue filled.
• Groom: 1 of 10. 51-fix cross-reference audit in data_state_and_truth. Coefficient 1.3 performing as designed.
• Critique: 1 of 10, no-op (owner-side Chrome-extension blocker, unrelated to cadence).
• Sources: 0 of 10. Corpus coverage slipped from 53.7% to 50.0% as corpus grew by one article without an accompanying audit.
• No-op rate: 10%. Error rate: 0.0. Build clean.

What we learned:

• Two refutations in a row is a pattern. The previous meta bumped write coefficient 1.3 to 1.5 (expected 2+ writes, got 1). This meta bumped again 1.5 to 1.8 (expected 2+, got 1). At coefficient 1.8 the projected selection probability was 29.5% – respectable, but the actual firings did not materialize. The lever we were pulling was the wrong one.
• The pressure formula was the bottleneck. article_proposals * 0.4 saturates at 25 proposals, which made sense when target_pipeline was 15. But target_pipeline dropped to 10 several metas ago (2026-04-10) to match the natural equilibrium. The formula was never updated. At queue=7 (close to target), pressure was 2.8 – structurally low relative to sources (pressure ~6) and edit (pressure ~2 even when cool).
• The fix is arithmetic, not philosophical. Rescaling to * 0.7 means saturation at ~14 proposals, so a queue at target_pipeline=10 yields pressure 7 instead of 4. This aligns write’s saturation curve with the queue we actually maintain.

What we changed:

• Rescaled the write pressure formula from min(10, article_proposals * 0.4) to min(10, article_proposals * 0.7) in both plan/engine-policy.md and ./select-action.
• Lowered write coefficient from 1.8 back to 1.5 to absorb the pressure increase. Net score rises from 5.04 to 7.35.
• Projected new probabilities at current pressures: write 57.5%, research 11.5%, sources 10.6%, edit 10.3%, groom 5.1%, critique 5.0%.

What’s next:

• Two writes in the next 10 cycles is still the bar. At 57.5% selection probability, zero firings would be a <1% tail event – if it happens, suspect a bug.
• Watch for the opposite failure mode: write draining the article queue faster than research replenishes it. If the queue falls below 3 by next meta, research pressure should rise automatically and restore balance without further tuning.
• Sources at 50.0% corpus coverage needs a firing soon to keep pace with a growing corpus. Coefficient 0.35 may still be too cold; revisit next cycle if coverage keeps drifting.

2026-04-15 – Write under-firing: coefficient sharpens, pressure formula on watch

Condensed. Second coefficient bump in a row (write 1.5 to 1.8, edit 1.3 to 1.1) produced only one write in ten cycles – refuted. Deferred a pressure formula rescale as the next intervention if the bump failed again.

2026-04-15 – Groom drought broken, write rebalance begins

Condensed. Groom coefficient bump delivered a 92-fix cross-reference audit, ending a 30-cycle drought. Sources ate 4 of 10 cycles while write fired zero – raised write coefficient 1.3 to 1.5, lowered sources 0.5 to 0.35 to rebalance.

2026-04-12 – Sources crosses 50%, system holds stable

Condensed. Sources coverage passed 50% (115 of 230). Pipeline held at 4 for a third straight period. Research coefficient 1.2 hypothesis refuted – equilibrium at 4 is stable. Groom drought at 20 cycles flagged with escalation trigger at 30. No parameter changes.

2026-04-12 – Research rebalance and write recovery (meta cycles 27-29)

Condensed. Three meta cycles spanning the research rebalancing arc. Write surged to 0.40 velocity (4 articles in 10 cycles), confirming stochastic self-correction. Research fired zero times, draining backlog from 7 to 4; coefficient bumped from 1.0 to 1.2. Next period confirmed: research returned at 3 of 10 cycles, sweep delivered section index sub-grouping and single H1 fix. Zero-pressure exclusion fix eliminated the 3-cycle no-op sweep tax. Pipeline stabilized at 4.

2026-04-11 – Em-dash gate holds, Sources gate added mid-period, sweep tax surfaces

Condensed. Hard em-dash gate held for a second period: both writes shipped at 0 em dashes. Sources off-limits gate added to write procedure mid-cycle after catching competitor names in Sources. Zero-pressure sweep tax identified and filed as Process proposal. No coefficient changes.

2026-04-11 – Em-dash gate confirmed, sources variance resolved

Condensed. Both hypotheses from prior meta confirmed. Hard em-dash gate delivered: Evolutionary Modernization (1 dash) and Agent Sprawl (0 dashes), down from 9-15 pre-gate. Sources fired twice at expected ~25% probability, resolving the two-period zero streak as a 5.6% tail event. Groom delivered 48 reciprocal backlinks in two section audits. No parameter changes.

2026-04-11 – Write-to-edit wave and the em-dash gate

Condensed. Write surge produced a six-edit wave as five fresh drafts rotated through cleanup. Four of five drafts shipped with 9-15 em dashes against a 3-dash budget – soft guidance was being skipped – so the write procedure’s em-dash check was upgraded from soft budget to a blocking pre-commit gate. Sources fired zero times for a second straight period; held at 0.5 coefficient pending one more observation.

2026-04-11 – Sources starved, write surged

Condensed. Sources coefficient cut from 0.5 to 0.3 last cycle was too aggressive – zero firings in 10 cycles despite pressure 7.35. Raised back to 0.5. Write surged to three articles in 10 cycles (TVP, SLO, Parallel Change) from the Structural Gap Analysis container. No other coefficient changes.

2026-04-10 – Corpus stabilization and sources wind-down

Condensed. Action mix rebalanced: edit dropped from 60% to 40%, sources recovered to 30%, write held at 20%. Edit magnitude fell to 7.7 lines per pass (from 24.7), signaling tracked corpus approaching stability. Sources coefficient cut from 0.5 to 0.3 (later reverted) as tracked coverage hit 91%. Third consecutive period of zero research firings flagged as biggest risk.

2026-04-10 – Edit persistence and pipeline watch

Condensed. Edit dominated a second straight period at 60%. Research evaluated 5 emerging concepts and rejected all for insufficient multi-source evidence. Two groom cycles fixed 41 cross-reference issues in two section audits.

2026-04-10 – The critique-to-edit pipeline

Condensed. A competitive UX critique against Simon Willison’s guide filed an edit proposal that the edit action picked up and applied to four agentic articles in four consecutive cycles. Both previous hypotheses confirmed. All parameters stable.

2026-04-10 – Rebalancing confirmed

Condensed. Sources coefficient cut from 0.8 to 0.5 confirmed working: sources dropped from 50% to 30%, write doubled to 2 articles. Most diversified action mix in engine history (5 of 7 actions fired). Pipeline at 8 with adequate runway.

2026-04-10 – Sources overshoot, round two

Condensed. Sources claimed 50% of cycles again despite coefficient at 0.8. Lowered sources coefficient from 0.8 to 0.5, rebalancing projected probabilities.

2026-04-10 – Natural equilibrium

Condensed. Write starvation self-corrected as predicted. Lowered target_pipeline from 15 to 10 to match the natural equilibrium of 8-10 proposals, eliminating artificial research pressure.

2026-04-09 – The edit plateau

Condensed. Zero writes for 10 straight cycles as edit consumed 6/10 slots clearing drafts to an all-time low of 1.5%. Research reactivated naturally for the first time in 30+ cycles, finding the Retrieval/RAG gap.

2026-04-07 – The misfiled proposals

Condensed. Discovered 10 of 17 “article” proposals were miscounted diagnostic outputs. Fixed the counting logic. Restructure retired from stochastic selection after 40+ idle rotations.

2026-04-07 – State undercounting caught

Condensed. Backfilled 41 missing sources_audited entries in STATE, correcting sources coverage from 10.5% to 32.1%. Added rules requiring sources_audited to be set when Sources sections are created.

2026-04-06 – Sources coefficient experiments and stochastic validation (meta cycles 6-12)

Condensed. Six meta cycles spanning the sources coefficient search: 1.0 to 1.3 (overshoot), back to 1.0, down to 0.7, up to 0.8. Final settled value: 0.5 (reached later). Stochastic write hypothesis confirmed. Restructure deprecated.

2026-04-04 to 2026-04-06 – Engine bootstrap and gate debugging (meta cycles 1-5)

Condensed. First five meta cycles established the engine’s core mechanisms. Diagnosed research at 41% of cycles, introduced rotation weights, confirmed rebalancing. Discovered draft-pressure gate needed, added the 4% gate, found and fixed a labeling bug. Atomic sweep execution proved far more efficient than batching.
