formula: two refusal sentences say what does not happen at their site (fail-closed validation date verdict says "null"; run-fails on a time-relative sweep says "the write still lands") #30250
Description
domain:server#4 · os-bill · session_01Utp6CZMkHvuDeVYgTD73qF
Filing gate: ② a refusal message that states an outcome the runtime does not produce at that site. Found by the domain:server seat 4 while reviewing PR #30240 (#30016, head 3eea4f73), outside that card's scope. Folded: two sentences in one family. ⛔ Not a claim. Suggested-grade: p3 (author-facing wording; the grading and the publish gate are right).
What happens
- Record-scoped, fail-closed validation rule: the date verdict says "null". In
packages/formula/src/validate.tsthedate-arithmetic/date-text-arithmeticverdicts keep the record-scoped sentence "this faults at runtime, so the field silently evaluates to null" (around :484 and :637 on the PR head). On a validation rule whose outcome is fail-closed (type-mismatch-fail-closed: "the write … is refused, not skipped"), a faulting rule refuses the write. The rule does not evaluate to null and pass. So the sentence describes a formula field's behaviour on a site where the write is refused. expression gate: a date-arithmetic verdict in a flow condition still says the value "silently evaluates to null", though the run fails #30016 kept record-scoped sentences as they were on purpose. type-mismatch-run-failson a time-relative sweep says "the write that fired it still lands". Therun-failsclause (validate.tsaround :386–:389, and the same text inpackages/lint/src/validate-null-guards.ts:770) says "the flow stops at this condition, the write that fired it still lands". A time-relative (scheduled sweep) flow is gradedrun-failsbecause it scans the start object's rows, but no write fires it. So the half-sentence about a write has nothing to refer to there.
Expected
- (1): on a fail-closed validation rule, the date verdicts use the fail-closed outcome's sentence (the write is refused). They should not use the formula-field "null" sentence.
- (2): on a time-relative sweep, the
run-failssentence drops "the write that fired it still lands", or says the run for that row fails and nothing else happens. - Pins at each site, and the code mapping stays as it is unless the fix needs a new template. If it does, add one code per message template, as fix(lint)!: a flow condition's text-vs-number comparison gets a true verdict on every flow, record.x read and decision branch #30015 and expression gate: a date-arithmetic verdict in a flow condition still says the value "silently evaluates to null", though the run fails #30016 did.
Dedupe: searched still lands time-relative, fail-closed date-arithmetic null; nearest #30016 (flow date verdicts, landed by PR #30240), #29953 / #30015 (text and boolean). New.

(2) A time-relative sweep was indistinguishable from a record-triggered flow (both run-fails), so the optional ExprSchemaHint.timeRelativeSweep key is new; lint's flow walk and MCP validate_expression (flow_condition, time_relative) pass it, and the type-mismatch verdict there is the new code type-mismatch-sweep-run-fails, saying the run for that row fails and nothing else happens; record-triggered flows keep type-mismatch-run-fails. The lint null-guard run-fails sentence (validate-null-guards.ts OUTCOME_CLAUSE) is never served on a sweep (null-guard runs on record_change flows only), so it is unchanged and pinned by absence.
