Three confirmed false-positive shapes in findUnverifiedCoachNumbers/
stripUnverifiedNumbers were replacing legitimate prose with the literal
"[unverified]" placeholder even though the underlying data was grounded:
- A correctly-computed delta, midpoint average, or percent change between
two of a payload's own headline aggregate figures (e.g. "down 3.5 kg from
your 7-day average") was never itself a raw leaf in any tool result, so it
was flagged as invented. The authoritative set now also carries the
pairwise delta/average/percent-change between a SINGLE payload's own
named aggregate fields (latest, avg7, avg30, avgSys30, allTimeAvg, ...),
scoped per payload so a weight delta cannot ground itself against an
unrelated metric's figure.
- The always-sent DATA INVENTORY manifest (tool-mode base context) carries a
sample count per domain, but that count was never added to the
authoritative set the way the pinned workout-evidence block already is —
so a plain restatement of a domain's count ("you've logged 42 BP
readings") was flagged whenever the model didn't also call that domain's
retrieval tool in the same turn. The inventory entries now splice into
toolResultPayloads exactly like workoutEvidence.
- A calendar-date ordinal ("July 21st") or a numbered-list marker ("1. Cut
back on sodium") tokenised as a bare number and, when ungrounded, got
soft-stripped mid-word into visibly broken text ("July [unverified]st").
Prose is now masked for these two narrow, high-precision shapes before
numeric extraction; the original text used for stripping is untouched.
A genuinely fabricated figure (unrelated to any grounded point, inventory
count, date, or list marker) is still caught and stripped — covered by new
adversarial cases alongside each fix.
Investigated and ruled out: multi-round tool-loop result accumulation (all
present results across every round already reach the verifier); unit
conversion (the app resolves and serves one consistent unit, so there is no
independent conversion step for the model to get wrong). The Daily
Briefing's separate withhold-a-whole-section grounding gate is unrelated to
the reported symptom (a different failure mode, whole-line omission vs.
inline replacement) and was not touched.
