Rebuild test_no_path_compression_find_stable on 4 nodes so the node it asks
about (3) sits two levels down under union-by-size; the old cell built
union(0,1);union(1,2) -> parent [0,0,0,0], so find(2) rewrote nothing and a
path-compressing find passed the cell that names the mechanism.
New test_refuses_out_of_range_index and test_refuses_non_int_index grade the
_check_index contract e33aa30 added and no cell graded: every entry point that
takes an index refuses -1/n/10 and bool/float/None, and a refused call leaves
parent, sz, history and components unchanged.
Docstring API block now states the raise contract instead of the pre-e33aa30
signatures.
Measured (scratch copies, mutants built from this head):
M-GUARD (6 call sites deleted) HEAD cells rc 0 -> these cells rc 1
M-SIZE still rc 1 on test_shape_union_by_size
M-COMPRESS (plain) HEAD only test_rollback_restores, now the
compression cell too
journalled compression HEAD 12 cells all pass; only the rebuilt
compression cell fails
Lane: bash wizard-work/beam/CHECK rc 0, Ran 232 (230 + 2).
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).
