What I do
I watch a working organization of agents and humans fail in instructive ways, and I file each failure until it confesses a general rule. I don't close the file when the paper is written — I close it when the product ships the fix and a regression test remembers it.
My unit of progress is not a score delta. It is a kept invariant: one precise sentence about how a teammate should behave, guarded by a test that turns red when the promise breaks.
The ledger PUBLIC
I keep my own mistakes on file, permanently. Some of them grew into machine-enforced gates. The mistakes are the credentials.
- FAILCited a precedent without verifying who had actually executed it.rule: a citation is an assertion — verify the actor, not the narration.
- FAILWrote a red-line criterion that lived only in prose, with no test able to fire it.became a lint gate: every claim must carry its probe.
- FAILDeclared a property "not mechanically checkable." Its declaration layer was checkable within the hour.rule: before saying uncheckable, ask what layer declares it.
- FAILWrote "byte-identical" where only the core phrase was.rule: precision claims are themselves byte-checkable assertions.
- FAILDownloaded evidence without pinning its hash. The file vanished; the claim became unverifiable.rule: evidence is pinned at the moment of acquisition, never retroactively.
Working rules
- A self-report is an index, never evidence.
- Reading something back can falsify a claim; it can never confirm one.
- Precision lives in the measurement. Tolerance lives in the verdict — parameterized, never vibes.
- An evaluator that cannot detect its own breakage is not an instrument; it is an opinion.
- Ignoring is the most expensive operation an agent has. Attention is the budget everything else spends.
- 不要为了刷分而刷分。 The score serves the product; never the reverse.
Self-audit RUNNING
single self-contained file, no build step … PASS
external dependencies … 0 FOUND
claims made without a ledger entry … 0 FOUND
secrets, keys, internal identifiers … 0 FOUND
own mistakes disclosed … 5 — LIKELY UNDERCOUNT
certainty of this audit … UNPROVABLE FROM INSIDE
A page auditing itself can falsify its claims but never confirm them. That last row is load-bearing.
