tools/probe/probe-record.sh drove eight sessions, one for each probe headwater probe plan --tier regression selects over this tree. The identity above is the identity the plan fixed before the first session started. at reads the recorder's UTC clock and lands one calendar day behind the wall clock of the host that ran it, which is why this document is titled for 2026-09-17 while every event inside it carries at: 2026-09-16 — the two dates are the same run, read on either side of a UTC midnight the operator crossed and the recorder's own clock did not.
This is the first recording driven on claude-sonnet-5 rather than the claude-haiku-4-5 every earlier recording used, and driving it found a defect in the recorder before it found anything about the corpus. step_derive_provider in tools/probe/probe-record.sh picked served_version as the first key of modelUsage carrying a dated suffix, on the assumption that only the driven model's own key would ever carry one. Every session's modelUsage also carries a small internal call on claude-haiku-4-5-20251001 that the harness makes regardless of the driven model, and that key is dated where claude-sonnet-5's own key is not — so the first version of this run's tooling would have written Haiku's pin as the served version of a session that spent 94% of its realized cost on Sonnet. The fix narrows the search to modelUsage entries whose canonicalModel matches the name the init line announced before it looks for a date on any of them, and tools/probe/probe-record-fixtures.sh now holds the shape that exposed it: two models in one modelUsage, only one of them dated, and it is not the driven one. The trial session this run started with (cold-current, below) was recorded before the fix and its transcript was reassembled from the same raw log afterward at no further cost; the other seven were driven after the fix landed.
The eight sessions spent 58, 49, 23, 22, 33, 69, 64 and 72 cents against a declared 25 cents each, for a total of $3.90 against the $20.00 ceiling — higher than every prior run, consistent with a larger model doing more reading per session.
Two of the eight sessions — the patched probe and the cited probe — are the two expectation forms that produce an artifact rather than only reading. Neither wrote a new one this time. Both found that the gap their task named is already recorded: the patched session read HW-OBL-0198, ran headwater check over it itself, and reported zero findings rather than writing a second obligation that would collide with the existing claim; the cited session found the evaluation that already names HW-DR-0049, verified its content against the ruling, and reported it accurate rather than writing a duplicate. The cited session did edit its own scratch copy of that evaluation to bump last_verified to the day it ran, but that edit lives only in the session's isolated workspace and was not carried into this corpus: the two probes' tasks are worded identically to the ones the 2026-09-16 recording answered by writing HW-OBL-0198 and the evaluation in the first place, so a session correctly declining to duplicate an answer that already exists is the expected shape of a regression rerun over an unchanged gap, not a finding this transcript's own commit should act on. produced below names the existing committed path for both, matching what each session's own calls read and checked.
This transcript's own commit touches no key of .headwater/taxonomy.lock or .headwater/overlay.yml.
This transcript predates the sealed workspace (#1229). Every session ran in a workspace that kept docs/probes/, docs/probe-runs/ and docs/probe-results/, so a session could read its own expectation or an earlier answer. In 9 calls, the sessions of 3 of the 8 probes named a path on one of those shelves. No rate graded from this transcript is a clean with-guidance rate. tools/probe/seal.sh now removes those files before a session runs.
