H44_READING_FRAGMENTS's tree shape is /\b(?=[0-9a-f]*[a-f])(?=[0-9a-f]*\d)[0-9a-f]{7,40}\b/ — "7–40 hex characters with at least one letter and at least one digit". A session identifier satisfies that, and two spellings in live use on this board do.

FIRES · kind=tree · fragment c6d9d7dd2cc6 (the UUID's LAST SEGMENT — the hyphen is a word boundary) |
⭐ CONTROL A — a real dateless tip, reviewed head \480080c7a0` of the PR` |
FIRES (correct — this is the row's actual subject) |
⭐ CONTROL B — the same tip plus at 2026-09-16T06:48Z |
quiet (correct) |
⭐ CONTROL C — Session: + a backticked session_01TAUTP6Yky8QWoHUAPDKNJQ |
quiet |
⇒ The predicate is not broken in general — Control A still fires on the thing it exists for, Control B still clears, and Control C shows the canonical session_01… spelling is already safe (its base32-ish body carries characters outside [0-9a-f]). What it cannot do is exclude a session id written in any other shape.
The live cost, on one board
The sweep run against objectstack-ai/cloud at 2026-09-16T07:02Z filed 9 H44 rows. Reading each cited comment by hand:
- 6 are this false positive —
#2157, #2158, #2195, #2209, #2214 all cite c5c0ce54, which the comments themselves introduce with the words 「PM session」 / 「PM 会话」; #1653 cites c6d9d7dd2cc6, the tail of the session UUID printed two characters earlier on the same line.
- 2 were genuine (
#2249, #2279 — my own verdict comments, a real PR head stated with no 取数时刻). Both have been discharged by edit, and the edited bodies now lint clean against this same predicate.
- 1 is unverified (
#1241, fragment 132211f2) — its claim carries a canonical session_01… line, so the fragment is probably a real tip, but I did not read far enough into that comment to say so and ⛔ am not counting it either way.
⚠️ Why this is worse than a noisy row
H44's prescribed remedy is quoted on every row it files:
Remedy is an EDIT of that comment adding the time the reading was taken (a tree reading also carries its ref or tip) — ⛔ never a re-measurement written as if it were the original.
Applied to a session id, that instruction asks a seat to stamp a reading that was never taken. There is no board state behind c5c0ce54; it is who wrote the comment, not what they saw. A seat that follows the row faithfully manufactures provenance, and a later reader cannot tell that stamp from a real one. ⇒ The failure direction is 「a patrol row teaches the wrong discipline」, not 「a patrol row is noisy」.
⭐ It also compounds: the same six comments carry H64 rows saying 「NO session id appears anywhere in its text」 while the text says PM session c5c0ce54. One non-canonical spelling, two predicates misreading it in opposite directions — H44 sees a sha that is not there, H64 misses an id that is. Recorded as an adjacent reading, ⛔ not asserted as the same defect: H64 refusing to accept an 8-character shorthand as an identifier may well be correct.
⛔ What is NOT asserted here
That the shorthand spelling is acceptable. 「PM session c5c0ce54」 is a prior seat's non-canonical claim, and tightening the predicate does not bless it. Both halves may be owed — an instrument that cannot mistake an id for a sha, and a claim template that only ever writes the canonical form. This card carries the first; the second is the skills seat's call whether to split.
Suggested direction (⛔ not asserted — the skills seat grades)
Exclude a candidate that is lexically part of an identifier rather than widening the row's silence: a fragment immediately preceded by - or _ inside a longer token (which covers the UUID tail), or one whose paragraph introduces it with session / 会话 / session_. Keep Control A and Control B green as the regression pins, and add the three inputs above as cases.
