The 2026-09-03 repair plan rested on one claim: that human_turns() is an
existing, controlled discriminator, and wiring it into four transcript
consumer sites was plumbing rather than classifier-building.
Tested against ground truth taken from the fool's own prompt text — not from
the function under test — the claim is false. 24 known mumbles, 41 known
non-mumbles, out of 65 transcripts:
must-detect 22/24 two mumbles read as human-attended
must-not-flag 35/41 and one "failure" is correct — b7e7eb39 is the
unattended session of 2026-08-31, which genuinely
has no human turn
human_turns() == 0 never meant "mumble". It means "nobody spoke", which is
equally true of an unattended real session. A mumble embeds the previous
session's text and so inherits its slash-command markers; it is excluded
only when the session it quoted happened to contain one. The two leaks are
exactly the two marker-free mumbles. Coincidence, not design.
No repair was made at any site, and no replacement discriminator was built.
Three controls passed and a fourth broke: all three test the question the
function was built for, none could see the question it was being reused for.
A successor written now inherits whatever made the first set look sufficient.
Also here, per the 2026-09-03 handover:
- step 0 preservation ran: 76 transcripts, read-back PASS, 11 of them
already pruned at source and surviving only in the archive
- gate 2b: the composition claim in PENDING-178 stands (11 mumbles,
~a fifth, on 08-31). Two terms do not close and are reported as an open
disagreement, not a correction — the reconstruction is a demonstrated
lower bound and -178 enumerated live
- gate 2c: five sites in four files; -178's [HARDENING] scope holds
- MEMORY.md record-only arithmetic correction: N-now 44 -> 65 measured,
composition 41 real + 24 mumble added, direction reversed (it is rising,
not shedding), stale :331 pointer corrected to :513
Filed as an item rather than a PENDING-178 addendum on PENDING-145's
mechanism: a ruling claims a number, so an addendum would be suppressed the
moment -178 is ruled. The undecided filing moratorium is disclosed inside
the item.
governance-drift-check.py:513 excluded on receipt and not examined.
