Slice B.0 — read-only re-validation of cronus's procedural-events design
against the live youpc Supabase paliad schema, 24 h after the design was
authored.
* Adds docs/design-procedural-events-b0-findings-2026-05-26.md with the
drift table, per-check confirmations, and a tightened B.1 brief.
* Annotates the cronus design doc's status header to point at the B.0
findings file so future readers see both together.
* Fixes the self-contradictory sentence in §1 that referenced
`deadline_rule_id` on both sides of a "not" — the live column is
`paliad.deadlines.rule_id`, renamed directly to
`paliad.deadlines.procedural_event_id` under Slice B (no intermediate
step). Matching fix patched into the m/paliad#93 issue body via
Gitea API (curl --netrc-file ~/.netrc-mai PATCH).
Key drift surfaced (vs design 2026-05-25):
- deadline_rules rows 254 → 231
- distinct submission_codes 158 → 153 (10 _archived_litigation.* codes
gone — Q5 multi-row collapse premise is now MOOT)
- distinct legal_sources 70 → 87 (+17)
- concept-linked rules 125 → 129
- paliad.deadlines rows 1 → 5
- submission_drafts rows 4 → 7
- live mig head 123 → 133; next available = 134 (not 124)
No migration SQL written. No writes to paliad.deadline_rules. Researcher
stays parked pending m's B.1 greenlight.
Note: this commit also cherry-picks the original inventor design doc
(5bb6df6) onto the B.0 branch, because the design was never merged to
main and the doc bug fix needed somewhere to land.
