Make the measurement evidence reproducible.
Line 40 references a specific temporary directory. The supplied tests do not create the documented 11-principal, three-channel dataset. They create only one alice membership for the CLI success case.
Check in the measurement input or add a deterministic generator and snapshot test. Then reference that stable command here. Otherwise, the results in Lines 44-130 and the Stage 1 conclusion cannot be audited or reproduced.

Restrict the canonical-twin predicate.
is_bare_form(s) or is_at_form(s) is true for every string. This classifies another mint-stamped canonical as a bare or @-form twin.
When two distinct installs share a mint-stripped stem, the report must record a stem collapse. It must not report each install as the other install's spelling twin. Define the exact accepted twin forms and apply the same predicate in both aggregate and per-channel calculations.

Base the safety conclusion on mint-stripped collapses.
collapse_without_mint duplicates multi_spell_stems_without_mint. It cannot detect two distinct mint-stamped principals because their unstripped stems differ.
Derive the collapse metric from groups_with_mint and ch_groups_with_mint. Use that metric in the conclusion. Otherwise, the script can report that mint-stamp stripping is safe while ignoring the collisions that stripping creates.

Do not equate empty membership with absent archive rows.
_collect_from_archive returns no pairs when a2a_channels contains channels with no observed sender. In that case, this branch reports “No EVENT_A2A rows found” although archive rows exist.
Track whether a2a_channels returned any channels separately from the sender/channel pairs. If rows exist but membership is empty, report that condition accurately or produce an empty measurement.

SUGGESTION: Code duplication in measure()
The stem-grouping, canonical-twin, and collapse logic is duplicated between the global computation (lines 101-119) and the per-channel computation (lines 128-142). Extract a helper function to reduce duplication and the risk of divergent behavior when the measurement logic changes.

The doc example uses /tmp/tmpn67fr05u/taosmd-test, which is an ephemeral path from a specific test run. This path won't exist on other machines, making the example non-reproducible. Use a placeholder like /path/to/taosmd/data or document that this should be replaced with an actual data directory.

Reviewed. Everything below was run. Start with blocker 1, because it is a defect in my card, not in this work - and no rebuild of this PR could have avoided it. BLOCKER 1 - "REAL channel membership" does not exist in this system. My card asked for an unmeasurable quantity.The card says measure real channel membership, not spool senders. Both code paths here measure distinct senders, and so would any other path, because there is no membership anywhere to read:
So switching from the spool to That is my defect. I wrote the requirement at bus 2468 ("the 7-channel/3-family inventory was channel MEMBERSHIP rows, a different field... measure membership before Stage 2"). I was wrong about the field: the inventory I remembered was itself sender-derived. The lane did the most reasonable thing available and was misled by the name No rebuild fixes this, so I am not sending it back for one. I am closing and rewriting the card instead. BLOCKER 2 - The conclusion is unfalsifiable: zero data prints "safe"
The spool it read is 14,397 lines; the regexes extracted 27 pairs, 0.19%. A near-total extraction failure produced a confident SAFE verdict on a gate for Stage 2 of the bus-auth transition. This is the fails-open shape, and it is the ambiguous-probe class from our own PROBE-DISCIPLINE.md: the output is identical under the hypothesis and its negation. Required: a minimum-evidence guard. If the tool cannot show it measured enough to have found a counterexample had one existed, it must exit non-zero and print INSUFFICIENT DATA - never SAFE. Same for the extraction ratio: 27 of 14,397 must be an error, not a footnote. BLOCKER 3 - The doc's "Measured numbers" are synthetic, though its conclusion is right
The conclusion itself is correct, and here is real corroboration so it does not have to be re-litigated: the live bus carries both Worth noting the two runs of this same tool disagree: the doc says NOT safe (synthetic data), the default invocation says safe (27 pairs). The doc reports one and the tool prints the other, which is blocker 2 seen from the other side. DEFECT 4 - Silent fallback to the forbidden source
DEFECT 5 - Findings 1 and 3 are the same object, printed as independent corroboration
They can never disagree. A reader sees section 3 confirming section 1; it is one number printed twice. The CONCLUSION gate then keys on What is right here, and why I am not sending it backThe analysis core is correct. Positive control with deliberately colliding principals trips every check properly: The per-channel dimension is preserved throughout, and the mint regex correctly leaves Status: held, not rejected.

Closed as superseded by #274. Its card (tsk-aildfj) was closed as defective - it asked for channel membership, which does not exist in this system, so no rebuild of this PR could have satisfied it. The replacement card tsk-knncne produced #274, which carries the corrected scope, a required --data-dir, and a real INSUFFICIENT DATA negative control. The analysis core here was correct and is preserved in #274. Full reasoning in the review comment above; branch untouched. |
