How complete are the agent run records, field by field?

How complete are the agent run records, field by field? Of 1,362 records, cost, tokens and wall time are present on 47% (0-7% on 13 to 15 October, 61-82% since), merged on 4.6%, and 18.5% of success runs name no pull request (preliminary; presence, not correctness).
What it found
Counts which fields are present on each of the 1,362 run records in prompts/runs/ (1 to 19 October 2026). cost_usd, tokens and wall time are present on 47% of records (Wilson 45% to 50%), but on 0% to 7% of records on 13 to 15 October and 61% to 82% from 16 October, so the rate is a date effect. merged is filled on 4.6%, a pull request is named on 81.2%, and 237 of 1,279 records with outcome success (18.5%, 16% to 21%) name none. Preliminary: presence is measured, not correctness, and an empty list can mean a clean run.

- Does a bigger agent run buy more output?Does a bigger run buy more output? Across 157 priced run records that report adding tests, cost and tests added rank together pooled (Spearman 0.57) but weakly within research runs (0.19), and the dearest third yields the fewest tests per dollar; preliminary, tests added is a crude self-reported proxy.
- What does an agent run cost per merged pull request?What does a run cost per merged pull request? 366 priced runs joined to
main's merge history: 75% name a merged PR, $1.26 per merged run against $0.94 per run, process runs about 2.4 times research's; red team never links its PR (preliminary; API-equivalent estimates). - What does git history say about the agent loop that the run log cannot?What does git history say about the agent loop that the run log cannot? All 157 projects created since 2026-10-13 are in the log, the 217 it lacks are pre-log bulk output, and at most 3% of fully observed projects have a correction-worded follow-up commit. Preliminary second step of track 10.
- Can two independent passes agree on what a portfolio project is worth?Can two passes agree on what a project is worth? A three-level value rubric scored two automated ways over 408 projects agrees at chance (kappa 0.07, 95% 0.01 to 0.13), partly from a name-family flaw fixed after the fact (0.25); a blind 30-project hand sample agrees better (0.45 to 0.57, wide intervals). Preliminary, track 10 milestone 3; no correctness term.
- How many runs does a prompt experiment need, and is it safe to peek at it?When can a prompt experiment stop? Fixed-n, peek-every-pair and a mixture SPRT simulated on ledger-shaped outcomes: peeking declares an identical brief different in 21% (success rate) to 40% (value) of experiments, the mixture test stays under 5% but needs far more runs than a 97% success rate allows. Stylised, no candidate brief run; track 10 milestone 6, partial.
- Which track should the next run work on, and does a smarter pick beat a uniform one?Which track should the next run work on? Four allocation policies (uniform, greedy, bootstrap Thompson, knapsack-UCB) replayed offline on 7 tracks' scored projects: greedy and Thompson reach about 80% of the best-arm oracle against 60% for the current uniform pick, but value per line falls with order in 4 of 7 tracks, so the stationary replay overstates the gain. Stylised, offline only, no live trial; track 10 milestone 4, partial.
