DAILY BRIEF · JULY 4, 2026

Rung Three Lands In Its Predicted Band

Rung three’s mission time came in at $t_c=702.6$ s, dead inside the pre-registered $[700,720]$ s band — the cleanest result of a pre-wall front-load that also took the website live and opened a math curriculum.

Evening edition, filed 2026-07-04 with the day still open — counts below are partial, and the session dashboard does not yet reach this date.

Major Developments

The science track led the day. With the LAN cluster back up, the three-box fleet was resynced from fresh monorepo clones, and the rung-3 decomposition run confirmed a mission time of $t_c=702.6$ s — squarely inside the band the lab report committed to before the run. The pre-slice actuation study fired on two seeds, matching its own pre-registration rather than an ad-hoc five.

Phase 0 front-load cleared its do-now slate ahead of the roughly 2026-07-07 API-only wall. The fragility harness was un-legacied, its provenance table reproduced and quarantined as thesis data, and four of seven pre-wall PDFs were acquired (the other three are paywalled). The research wiki grew from 50 to 54 sources with seven new pages across the CVaR and next-best-view queues.

A 16-lane infrastructure sprint ran alongside, peaking at 21 agents on single-writer lanes with zero collisions. It closed the equation-vault crosswalk, ported three of four risk metrics into the analyzer, shipped the daily-news skill you are reading, and added a Plotly orbit figure. The website expansion published 86 reports into a searchable /reports archive, added a plum dark mode, and deployed 903 files live agent-side. A new math-teacher skill produced lesson 1 on the error-floor cascade — seven gapped checkpoints, all six SymPy tests green. A notes-organization blitz renamed or moved 16 notes, repointed 48 generated_reports references across 22 files, and ran the first weekly staleness sweep.

Tried and Failed

• Rung three confirmed the timing band but violated the decomposition gate in the opposite direction (roughly $-189\%$): the gate’s deficit integral over-predicts about threefold on today’s-code logs, yet closed to 2–4% on the June 12 logs. A confirm-with-caveat, not a clean pass.
• A measurement that rebuilt run objects from log length under-sized the orbit grid and printed $t_c=427$ s on a 702.6 s mission. The pre-registered falsifier ($t_c$ below the kinematic floor is impossible) caught it before any conclusion shipped.
• Three website “publishes” turned out to be no-ops — inspection-ffsm is a direct-upload Pages project, so git pushes deploy nothing. Root-caused, then deployed live through wrangler and a scoped Cloudflare token.
• The Mac monorepo was silently shallow, so every box clone failed identically until git fetch --unshallow.
• A wifi outage killed 6 of 14 notes-workflow agents mid-run; the workflow resumed from journaled results and re-ran only the casualties.

Lessons Learned

• A file committed raw despite matching an LFS pattern phantom-dirties every fresh checkout; the fix is git add --renormalize.
• Un-ignoring a directory is not un-ignoring its payload — two 17.8 MB baselines stayed shadowed by *.npz. git status --ignored is the one-line audit.
• KaTeX errors on a raw underscore inside \tag{} text mode where MathJax tolerates it; escape it as \_.
• CronCreate is not cron: its jobs are session-only, and cloud routines cannot see gitignored local sources like .remember/. Daily-news stays a morning ritual.
• Verify the ping premise before relaying it: ONGOING §111’s “21-file batch still unblocked” had already landed in an earlier commit.

Questions and Ambiguities

• Which post-June-12 derate-path change moved the decomposition-gate deficit integral from 2–4% agreement to a threefold over-prediction?
• The effort metric has two live definitions — a dt-free step-sum versus a trapezoidal N·s impulse, differing by about 47×. The swap is blocked on the user’s definition call.
• notes/terminology.md exists twice (root at 166 lines, Inspection at 104), with each CLAUDE.md crowning a different copy canonical. Reconcile is boarded.
• The 0.02 threshold is pinned to floor 2 by test_singularity_floors.py but attributed to floor 3 by the wiki cascade page — an open Phase-D reconciliation.
• deriv_7dof.tex gives one symbol to two different right inverses (a Moore-Penrose block versus an M-weighted Khatib inverse); the locked tex is the lone carrier of that conflation.

Next steps

1. Return to the cluster and finish the pre-slice actuation reading — blocked only on cluster return.
2. Reconcile the rung-3 decomposition gate across the June 12 and today’s-code derate paths.
3. Resolve the effort-metric definition, then port the fourth risk metric.
4. Reconcile the two terminology.md copies and the 0.02 floor attribution.

By the numbers — the session dashboard’s range (2026-06-23 to 2026-07-02) does not yet reach 2026-07-04, so no per-day session, prompt, token, or cost figures are available. The day’s own countable work: rung-3 $t_c=702.6$ s inside the $[700,720]$ s band · 4 of 7 pre-wall PDFs acquired · research wiki 50 → 54 sources · 86 reports published · 903 site files deployed · lesson 1 at 6/6 SymPy tests · 16 notes renamed and 48 references repointed.
