Every reading now leads with "vs your own baseline", and no verdict is given
when N is too small to carry one.
- stats.ts: median + medianAbsoluteDeviation (robust pair; mean/stddev stay for
the alert engine, which wants outlier sensitivity), rollingBaseline with a
10-post positional window, median ± 1·MAD band floored at 0, and a typed
insufficient-data refusal below MIN_BASELINE_N=5. readAgainstBaseline returns
above/within/below-band, or no-verdict when the baseline was refused.
- baselineByGroup + buildBaselineBlock: per-format/per-pillar baselines, each
judged on its own N; the reported period is excluded from its own baseline and
compared on its median, not its mean.
- queue-join.ts (new): read-only date join supplying format/pillar from the post
queue. Every ambiguity resolves to unlabelled, an entry labels at most one
post, and a missing/broken queue degrades to no labels.
- weekly/monthly reports attach the block unconditionally (refusal included);
optional in the types, so pre-N17 reports load unchanged.
- CLI: report output leads with the baseline; new `baseline [--by format|pillar]`
verb with coverage reporting.
- report.md leads with baseline framing and prints the code's reading rather
than judging the band by eye; WoW loses to the baseline on disagreement.
analyze.md Step 2a tests whether the drop is real before diagnosing it.
TDD: 58 analytics tests written red first (144 -> 202). test-runner Section 16x,
23 unconditional checks + self-test (247 -> 270; anti-erosion floor 228 -> 251).
tsc clean. All suites green: trends 300, brain 134, editions 72,
specifics-bank 45, contract-gate 33, hooks 191, tests 35, render 60.
Also closes the OKF phase-4 scope follow-up in docs/okf-ingestion/plan.md §8
(coord round 2026-07-25): phase 4 tracks the contract, parse is in scope, and
our claim on read_concept/navigate_bundle is withdrawn as unnecessary.
