Amend CB-EV-0001; add CB-WP-0002 for cost accounting AM-4: measured what each remediation option actually buys, rather than leaving one recommendation unquantified. serde_yaml optional removes 6 crates, not 5 — ryu belongs to that group, since serde_json now uses zmij for floats. Full ladder: -6 to 27, serde_json -4 more to 23, inlining SHA-256 -8 to 19, inlining ChaCha12 -4 to 15. Only reimplementing a primitive gets under 20, so the target is unreachable without undoing K5/K7. Also records that crate count compares badly across ecosystems, and offers the alternative the count is a proxy for: 307,317 lines of third-party source under audit against 3,398 of our own. AM-12: corrected from "uncomputable" to measured. The refusal to estimate was right; the claim that no instrument existed was wrong. Session transcripts carry exact per-message usage including the cache breakdown. This session cost $248.46 at Fable 5 rates, of which 53% is cache reads — cost is driven by context size times turn count, not by output volume. What is still missing is per-task attribution, since nothing marks task boundaries in a transcript. CB-WP-0002 makes cost measurable and attributable: survey the instruments, decide the attribution model by ADR, spec metrics that include cost composition rather than a bare total, build a collector whose positive control refuses to emit unreconciled numbers, and prove it by answering a question that could not be answered before.
