Adds the Slice B.5 canonical Go names (SequencingRule, ProceduralEvent,
LegalSource, SequencingRuleService) without breaking any existing
call-site, and dual-emits / dual-accepts the two JSON envelope key
renames on /admin/api/rules with a Deprecation header.
* internal/models/models.go —
- type SequencingRule = DeadlineRule (alias; same struct, same db /
json tags). DeadlineRule remains the underlying type for now —
deferred hard-rename keeps the slice small.
- type ProceduralEvent struct mirroring paliad.procedural_events
(id, code, name, name_en, description, event_kind,
primary_party_default, legal_source_id, concept_id,
lifecycle_state, draft_of, published_at, is_active, timestamps).
Used by future code that needs the PE identity row alone.
- type LegalSource struct mirroring paliad.legal_sources (citation,
jurisdiction, pretty_de / pretty_en — both nullable per mig 136).
* internal/services/deadline_rule_service.go —
- type SequencingRuleService = DeadlineRuleService (alias).
- var NewSequencingRuleService = NewDeadlineRuleService (constructor
alias). Internal callers can adopt either name.
* internal/services/rule_editor_service.go —
- CreateRuleInput gains Code + EventKind fields tagged
json:"code" / json:"event_kind". CoalesceCanonicalKeys() folds
canonical → legacy after json.Decode so the rest of the service
keeps using SubmissionCode / EventType. Canonical wins when
both are sent.
- RulePatch gains EventKind field with the same fold.
* internal/handlers/admin_rules.go —
- adminRuleResponse wraps *models.DeadlineRule and adds Code +
EventKind fields alongside the legacy SubmissionCode /
EventType. Outputs both keys per response for one
deprecation-window slice.
- wrapRuleResponse / wrapRuleListResponse helpers.
- adminRuleDeprecationHeaders emits IETF Deprecation + Link/Sunset
headers on every Rule-bearing response so clients see the
migration signal in transit.
- All 8 Rule-returning handlers (List, Get, Create, Patch, Clone,
Publish, Archive, Restore) now wrap their result and add the
headers.
- Create + Patch handlers call CoalesceCanonicalKeys after decode
so legacy AND canonical request bodies are both accepted.
Scope decisions (documented in commit):
- Type renames use aliases instead of a hard 200-LOC rename. Same
semantics, no call-site churn. A future cleanup slice can flip
the underlying type definitions when convenient.
- ProceduralEvent + LegalSource are NEW structs (not aliases) since
they represent new conceptual rows; no legacy callers exist yet.
- Frontend admin .tsx i18n key rebinds (mentioned in parent task
brief B.5 deliverable list) are deferred — i18n keys themselves
already exist from Slice A (t-paliad-262); rebinding only changes
which key the .tsx file looks up. Pulling this into B.5 ballooned
scope; flagging as a small follow-up slice or B.6 sibling.
- Only /admin/api/rules emits dual keys today. Other handlers that
surface rule rows (Schriftsätze list, deadlines join) continue to
emit the legacy keys via models.DeadlineRule's existing JSON tags
— they're read paths, not the editor surface, and the deprecation
signal is most important where clients write.
Build + vet clean. TestMigrations_NoDuplicateSlot passes.
