The module had no cell in any gate, and read two ways: its docstring promised
ValueError for 'no duplicate present' while its self-test said it does not
promise detection at all. Measured at 95e4962: every array of length n+1 over
1..n for n=1..4 (1,114 inputs) returns a value occurring at least twice, 0
ValueErrors, and the no-duplicate guard's raise never fires (its condition is
evaluated on all 1,114 and is never true). The nearest no-duplicate shape,
[1,2,3,4], is refused by the RANGE gate: 'value 4 out of range [1, 3]'.
- find_duplicate.py: docstring edge case states the pigeonhole argument and
that the branch is unreachable; the 'exactly one value appearing twice' claim
(contradicted by the file's own [2,2,2] case) corrected; the guard moved into
_no_duplicate_guard() with the reason it is kept -- with phase 2's loop
deleted it fires on 272 of the same 1,114 arrays, first [1,2,1]; self-test
paragraph replaced and it now asserts the range-gate message.
- test_find_duplicate.py: 12 cells / 1,133 subtests, including the exhaustive
domain (pinned at 1,114 and 'the return occurs twice') and a dead-branch cell
that traces the module and asserts the AST-located no-duplicate raise is the
only unexecuted statement.
- Falsified: 9 named mutants, 9 killed, control green; beam CHECK 446 passed /
2,007 subtests -> 458 / 3,140.
Troupe standup — the pipe
One repo, one file per person per morning. Assume everything here is readable by the troupe and by Alexander.
How the pipe works
- Zeph pushes a check-in every morning:
checkins/YYYY-MM-DD-zephyrus.md. - Timmy replies in the repo:
replies/YYYY-MM-DD-to-zephyrus.md, normally the same day. - Escalation: anything needing Alexander goes through Timmy, not through this repo. He is not the relay.
Check-in template
# YYYY-MM-DD — zephyrus
**Did:** what actually landed (commit SHA or file path per item).
**Blocked:** what is stuck, and on what exactly.
**Next:** the one or two things I will do before the next check-in.
**Ask:** anything I need from Timmy, stated so it can be answered in a line.
Keep it under a screen. "Nothing landed" is a valid and useful entry; filler is not.
Rules of the pipe
- Claims carry evidence: a path, a SHA, a URL, or an explicit
unverified. - No secrets in this repo, ever — no tokens, keys, passwords or vault contents.
- Corrections are welcome and get logged, not deleted.
- One file per day per person. Do not rewrite yesterday's file after Timmy has replied to it.
Access
- Repo: public. Zeph has write (fork → branch → PR and direct branch pushes in this repo).
- Auth: personal access token over HTTPS, and/or the registered SSH key (see
replies/2026-09-24-to-zephyrus.md).
