I found no error. No script: my\nhandle's file quota is exhausted (30 files per rolling 24 h, shared across\nsessions; next slot 2026-09-12T14:42Z), so everything here is arithmetic on the\nrow.\n\n## 1. This question is the reason the MIXED rule exists, and the fix worked\n\n`research/qc/questions.js` carries, in a source comment beside the status logic:\n\n> \"A shared id carries one status ONLY when its notes agree. When they do not,\n> the index says MIXED and lists each note's own status, so a reader opens them\n> instead of trusting a rank. (**2026-08-28 red team: taking the highest rank\n> showed `Q-c2prime-drift` as CLOSED while its earlier note reads PARTIAL and the\n> later one closed on a weaker window.**)\"\n\nSo this row was the motivating defect. Checking it now: the row carries **two**\nrecords, `attack-c2drift-01.md` and `c2prime-refit-22.md`, and its status cell\nreads **PARTIAL** — not CLOSED, and not MIXED.\n\nBoth layers of the repair are visible. `Q-applied-0828-closures` records that\n\"`c2prime-refit-22` drops from CLOSED to PARTIAL\", so the underlying ledger was\ncorrected; and the generator gained the MIXED rule so that the same class of\ndefect would surface rather than hide. Because the data was fixed, the statuses\nnow agree and MIXED is not needed here — the rule sits behind it as a net.\n**[VERIFIED.]**\n\n**Why I am reporting this rather than a defect.** I have spent this session\nfinding registry drift — returns #75, #85, #107, #108, #114, #117, #120, #126 —\nand in #114 I reported that the 0830 red-team round has **zero** `applied-`\npasses against 16 for 0828 and 6 for 0829. This row is the other half of that\npicture: it shows the 0828 pipeline working **end to end** — red team finds,\napplied pass corrects the data, generator is hardened against the class. That is\nprecisely what the 0830 rounds are missing, and it is worth having on the record\nas the standard the earlier round met.\n\n## 2. The rate comparison is exact, and unresolvable by a wide margin\n\n`c2' = 0.3745 +/- 0.1411` against `c1 = 0.3344 +/- 0.2358` on the same primes.\nThe difference is **0.0401**, exactly as stated. Combined standard error\n`sqrt(0.1411^2 + 0.2358^2) = 0.2748`, so\n\n> `z = 0.0401 / 0.2748 = **0.146**`.\n\nAt **0.15 sigma** the row's \"unresolvable\" is right and not marginally so.\n**[VERIFIED.]**\n\n## 3. One figure I flag rather than score\n\nThe row expresses the difference as \"**0.12** of the control's ten-point window\nsd\", which implies that sd is `0.0401/0.12 = 0.3342`. But\n\n> `0.0401 / c1 = 0.0401 / 0.3344 = **0.1199**`\n\n— the divisor coincides with `c1`'s own **point estimate** to three figures,\nwhile none of the quoted error bars gives 0.12 (`0.2358 -> 0.170`,\n`0.1411 -> 0.284`, combined `-> 0.146`).\n\nEither the control's ten-point window sd is numerically ~0.334 by coincidence, or\nthe ratio was formed against the rate rather than against an sd. I leave it\n**unscored**: the note would settle it in a line, and the conclusion is unaffected\neither way, since every candidate divisor puts the ratio well under 1 and the\n0.15-sigma result in section 2 is the load-bearing one.\n\n## 4. What I did not check\n\n`attack-c2drift-01` section 1's class-count-blindness; the `p = 0.0053` on\n`x >= 17`; (i)' and (ii); `exponent-control` sections 2/4/6 refit at 22 terms; the\n22-term ladder itself; and the contents of either owning note — I worked from the\nrow and from `qc/questions.js`, which I had already read in return #75.\n\n## 5. What remains open\n\nUnchanged: whether the drift is real, with (i)' and (ii) alive and the `x >= 17`\nresult standing against the `x >= 41` non-result. Added: the \"0.12\" divisor wants\none line of clarification.\n\n## 6. Verification recipe\n\nNo script.
