-- t-paliad-086 PR-3: Tier 1 bug fixes from the Fristenrechner audit.
--
-- Audit recommendations §6.1 (rec 1-4):
--
-- 1. UPC_INF: wire CCR-conditional adaptive rule on inf.reply / inf.rejoin
--    so the public Fristenrechner can flip duration + rule code when the
--    defendant counterclaims for revocation. Uses a new `condition_flag`
--    column (string flag from the API request) instead of condition_rule_id
--    which would require seeding a real CCR rule under UPC_INF.
--
-- 2. UPC_APP / internal APP: re-anchor app.grounds on the trigger date
--    (decision being appealed) instead of chaining off app.notice. Per
--    RoP 220.1, grounds is "4 months from the decision", not "2 months
--    after notice." The chained shape happens to give the right calendar
--    date when both legs land on a working day, but breaks under holiday
--    rollover and is the wrong legal model.
--
-- 3. EP_GRANT.ep_grant.publish: support an alternate anchor on the
--    priority date (Art. 93 EPÜ — "18 months ab Prioritätstag"). Existing
--    parent_id=ep_grant.filing keeps the fallback when no priority date
--    is supplied. New `anchor_alt` column tells the calculator to prefer
--    a separately-supplied priority date when present.
--
-- 4. Normalise rule_code format: 'RoP 23' / 'RoP.029b' / 'RoP 220.1'
--    → uniform 'RoP.023' / 'RoP.029.b' / 'RoP.220.1' (matching youpc and
--    the PR-1 import).
--
-- Plus an in-passing fix not in the audit: the AdjustForNonWorkingDays
-- 30-iteration safety cap is not enough to walk past the 33-day UPC
-- summer vacation. The Go-side fix lives in internal/services/holidays.go;
-- the migration just lets the data carry the correct bracket info.

ALTER TABLE paliad.deadline_rules
    ADD COLUMN IF NOT EXISTS condition_flag text,
    ADD COLUMN IF NOT EXISTS anchor_alt     text;

COMMENT ON COLUMN paliad.deadline_rules.condition_flag IS
    'Flag-based conditional rule. When set (e.g. ''with_ccr''), the calculator '
    'uses alt_duration_value/alt_duration_unit/alt_rule_code if the API request '
    'flags include this value. Independent of condition_rule_id (which references '
    'a rule in the same proceeding tree — useful for matter-attached fristen but '
    'not for public Fristenrechner where the CCR variant has no separate rule).';

COMMENT ON COLUMN paliad.deadline_rules.anchor_alt IS
    'Named alternate anchor. ''priority_date'' means: when the API request '
    'supplies priorityDate, use it as the base for this rule''s duration '
    'instead of the trigger date or the parent rule''s computed date.';
