Most of the day went into making the agents' own tooling harder to misuse. The biggest theme was fabricated reports: one change teaches the session-inspection tool to spot a helper's hand-back that was written by the agent itself (#2511), and another makes the end-of-turn check block a reply that invents a helper's report (#2515). A related fix stops a session log from being marked completed after a merge unless the closing step was actually run (#2536). Another change makes the friction-fixing job rank regressions by recent severity and skip ones already handled (#2548).

A review of the scheduled docs check found that about 19 of 25 recent wording-trim edits changed nothing a reader would do, so that part of the check was dropped (#2518). Two experiments in shortening agent instructions also landed (#2537, #2538), and the friction-fixing job's helper briefs were rewritten step by step (#2539).

On the visible side, the Glass Box textbook gained a "Find a Lesson" box on its landing page and shorter lesson teasers that no longer clip on phones (#2542, #2541). Its verification lessons were grouped under one subject (#2519), and its guide and drafts pages were brought up to date with the code (#2516, #2517).

Also shipped: #2549 clearer message when e2e reuses a build · #2550 hints find nested helper transcripts and the first helper dispatch waits until its guide is read · #2540 ledger tool files blocks under entries · #2529 and #2531 blog post and reply · #2501 yesterday's digest · skill and docs audits and fixes (#2502, #2507, #2509, #2510, #2525, #2530, #2532–#2535, #2512–#2514) · ledger records (#2506, #2508, #2524, #2526, #2547) Sessions: 18 (all completed) · Problems noted: 91 (52 trivial, 37 minor, 2 moderate) — worst: working out whether one docs-check lens earned its place cost about 270k helper tokens, because runs don't record per-lens finding counts.
