…ATE and NOOP 87fc33a switched the UPDATE guard from a truthy check to `!== undefined`, so an empty string started to be refused as a forged archive entry. A blank string displaces nothing and forges nothing; SUPERSEDE in the same function already reads the field through trim(). Models that fill every schema field send `history_entry: ""` on UPDATE, get the refusal and repeat the identical call until the provider rejects the turn (three sweep sessions of 296, 335 and 490 consecutive refusals on gpt-5.6-luna via codex). The tool now normalizes a blank history_entry to undefined once at its boundary and uses that for the UPDATE and NOOP guards and for the store call. ADD still receives the raw field so its noise-drop journal event is unchanged. A non-blank history_entry on UPDATE or NOOP is refused as before.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR makes a localized input-normalization change so blank history entries no longer cause false UPDATE or NOOP refusals. It is mergeable with owner awareness that the rejected NOOP path should also explicitly verify the card remains unchanged, a bounded test-confidence risk.

Verify that rejected NOOP does not modify the card.
After Line 621, assert that read(created.file) still equals before. The current assertion only proves that the rejected UPDATE preserves the file.

Production agent/tools/write_card.ts on this head is byte-identical to #207. Same boundary: history_entry?.trim() ? history_entry : undefined, ADD still gets the raw field, non-blank UPDATE/NOOP still refused. That is the right design (blank forges nothing; SUPERSEDE already reads through trim()). Verified the main-side bug: history_entry !== undefined treats "" as present.
#207 strictly supersedes the test. Here the rejected NOOP path asserts ok: false and the error string, then stops. It does not read(created.file) and compare to before. #207 adds exactly that ("rejected NOOP leaves the card byte-identical") plus a SUPERSEDE follow-up that the archive still works.
Please land #207 instead, or add that byte-identical assertion here. Not closing this PR.

Problem
Since 87fc33a the UPDATE guard in
write_cardcheckshistory_entry !== undefined, so an empty string is refused as a forged archive entry (history_entry допустим только для SUPERSEDE.). NOOP has the same check. SUPERSEDE, in the same function, reads the field throughtrim()— a blank string is "absent" there.Some models fill every field of the tool schema.
gpt-5.6-luna(codex / Responses API) sendshistory_entry: ""on UPDATE, gets the refusal, and repeats the byte-identical call: three business-sweep sessions on our deployment ran 296, 335 and 490 consecutive refusals (~300–500 model steps each) until the provider rejected the turn withBad Requestor we cancelled it. deepseek-v4-pro on the same skill simply omits the field, so this never showed up before.This is not #179. That PR sanitized
history_entryon all non-SUPERSEDE operations and was closed because UPDATE must keep refusing a real entry. This change keeps that: a non-blankhistory_entryon UPDATE or NOOP is refused exactly as before. Only a blank string — which displaces nothing and forges nothing — is treated as absent, matching how SUPERSEDE already reads the field.Change
