-`signal_events` counts the logged answers that moved any dimension, and `contributing_events` counts, per dimension, the logged answers that moved it (an answer that writes two deltas to one dimension counts once), so a dimension with no evidence (0) is visible beside one whose evidence balances out; both print 0.5 (#2623). Each value is the sigmoid of its accumulated deltas, and each UTC day's sum per dimension (by the row's `ts`) is clamped to the largest single delta in the signal map (currently ±0.06), so one burst of answers can't pin a dimension; `--trace <dim>` lists every contributing answer, each clamped day and the total. The bound keys on the day, not on `session_id`: the PostToolUse hook and the agent log different ids for the same review (the host's conversation id and the preamble's run id), and an agent can leave the `SESSION_ID` placeholder unsubstituted, so no logged id reliably marks one review. The cost is that several reviews on one day count as one. `contributing_events` still counts an answer logged by both writers twice. Only an ISO 8601 date or date-time `ts` counts as dated (a time without a zone is read as UTC), every other row shares one undated bucket, and `diversity.days_span` counts the same UTC days. Nothing displays `contributing_events` yet (#3436).

 **Diversity check** (Codex #13): `inferred` is considered "enough data" only when `sample_size >= 20 AND skills_covered >= 3 AND question_ids_covered >= 8 AND days_span >= 7`. Below this, `/plan-tune profile` shows "not enough observed data yet" instead of a potentially-misleading inferred value.
