Builds on t-paliad-159's UPC RoP audit. Drives from paliad's own corpus
outward: every active rule, every firm-wide event_type, every cascade
leaf — and asks whether a Determinator user can actually reach the row.
Headline finding: 71/76 (93%) of true Fristenrechner deadlines are
reachable from the cascade. The 5 unreachable cluster into one fix:
EP_GRANT (4 rules) plus UPC_INF.inf.app_to_amend lack cascade entry.
Adding an `ich-moechte-einreichen.ep-erteilung` subtree lifts coverage
to 100%.
Per-jurisdiction inventory (UPC, DE, EPO, DPMA) plus a §2.6 cross-cutting
table for the procedural-order categories m flagged (Hinweisbeschluss,
Beweisbeschluss, Streitwertbeschluss, Versäumnisurteil, R.71(3),
Beanstandungsbescheid, etc.).
§4 frames the smart-navigation choice: recommends P2 (persistent escape
button with capture) + P1 (free-text search per cascade level), defers
P3 (flatten deeper levels) until telemetry justifies it. The captured
"Mein Ereignis ist nicht dabei" texts feed both the gap-fill roadmap
and P1's ranking corpus.
No code changes; one markdown doc, 394 lines.
