1129baba7a feat(db,services): Slice B.4 destructive drop — paliad.deadline_rules retired, INSTEAD OF triggers on view route writes (mig 140, t-paliad-305 / m/paliad#93)
Some checks failed
Paliad CI gate / build (push) Has been cancelled

Drops the legacy paliad.deadline_rules table after 3 weeks of dual-write
shadowing (mig 136 → B.2 dual-write → B.3 read cutover via view). The
new tables — paliad.procedural_events, paliad.sequencing_rules,
paliad.legal_sources — are the sole source of truth from this commit
forward.

Pre-flip drift verified clean against prod:
  deadline_rules=231 == sequencing_rules=231 == procedural_events=231
  legal_sources=87
  missing_sr=0, orphaned_sr=0, mismatched_lifecycle=0

* internal/db/migrations/140_drop_deadline_rules.up.sql (new) —
  Single TX, audit-first:
  1. CREATE TABLE paliad.deadline_rules_pre_140 AS TABLE paliad.deadline_rules
     (precedent migs 091/093/095/098 — snapshot in same TX as destructive op).
  2. Final reconciliation UPDATE on paliad.deadlines (no-op when
     drift is already 0; defensive against last-minute writes).
  3. DROP TRIGGER deadline_rules_audit_aiud.
  4. Re-point FKs to sequencing_rules:
     - paliad.appointments.deadline_rule_id → paliad.sequencing_rules(id)
     - paliad.deadline_rule_backfill_orphans.resolved_rule_id → paliad.sequencing_rules(id)
     (the id values are identical — sr.id inherited dr.id at mig 136.)
  5. DROP COLUMN paliad.deadlines.rule_id.
  6. DROP TABLE paliad.deadline_rules.
  7. CREATE INSTEAD OF INSERT + INSTEAD OF UPDATE triggers on
     paliad.deadline_rules_unified. Triggers route writes into the
     three new tables in the same TX, preserving the legacy column
     shape on the wire so RuleEditorService SQL only needs a
     table-name swap, not a structural rewrite. Synthetic-code mint
     expression is byte-identical to mig 136 + the B.2 dual-write
     helper. POST assertions confirm the table is gone, the column
     is gone, and the snapshot matches.

  Trigger design notes (1:N caveat documented in-trigger):
  - PE identity columns (code, name, name_en, description, event_kind,
    primary_party_default, legal_source_id, concept_id) mirror from
    the writing sequencing-rule.
  - PE lifecycle columns (lifecycle_state, published_at, is_active)
    deliberately do NOT mirror — a draft sequencing-rule cloned from
    a published source shares the source's PE; we don't want the
    clone's 'draft' lifecycle to leak back onto the source's PE.
    Practical bound today (1:1 corpus); explicit comment in-trigger
    for the eventual 1:N pattern.

* internal/db/migrations/140_drop_deadline_rules.down.sql (new) —
  Best-effort restore from the snapshot. Triggers / indexes /
  CHECK constraints from historical migrations are NOT replayed;
  operator must reapply 078/079/091/095/098/122/128/134/135 to
  bring the restored table to working shape. The down path is for
  catastrophic recovery, not casual revert.

* internal/services/rule_editor_service.go —
  Six syncDualWriteFromDeadlineRule(...) calls removed (the
  INSTEAD OF triggers now do the fan-out). Five
  INSERT/UPDATE paliad.deadline_rules statements (Create,
  UpdateDraft, CloneAsDraft INSERT+SELECT, Publish, peer-archive,
  flipLifecycle) renamed to paliad.deadline_rules_unified —
  trigger handles the routing.

* internal/services/rule_editor_orphans.go — ResolveOrphan no
  longer writes deadlines.rule_id (column dropped). Sets
  sequencing_rule_id directly + derives procedural_event_id from
  the matching sequencing_rules row in the same UPDATE statement.

* internal/services/deadline_service.go — deadlineColumns now
  lists sequencing_rule_id (Deadline.RuleID still binds to it via
  the db tag rename below). Update path's appendSet("rule_id",…)
  flipped to appendSet("sequencing_rule_id",…) and post-write
  derivation moved to the renamed syncDeadlineProceduralEventID
  helper.

* internal/services/projection_service.go,
  internal/services/submission_vars.go — `WHERE rule_id = $X`
  reads on paliad.deadlines flipped to sequencing_rule_id.

* internal/models/models.go — Deadline.RuleID db tag changed from
  "rule_id" to "sequencing_rule_id". Field name + JSON name kept
  for backward compat with the frontend and existing Go callers;
  semantic value is identical (same UUID).

* internal/services/dual_write.go — Massively trimmed.
  Removed: syncDualWriteFromDeadlineRule, syncDeadlineDualLinks,
  CheckDualWriteDrift, DualWriteDriftReport, HasDrift,
  StartDualWriteDriftCheckLoop. All referenced
  paliad.deadline_rules which no longer exists.
  Kept (renamed): syncDeadlineProceduralEventID — derives
  procedural_event_id from sequencing_rule_id after any
  DeadlineService.Update that touched the back-link.

* cmd/server/main.go — Removed the StartDualWriteDriftCheckLoop
  bootstrap call (and its `time` import that only that call
  needed). Comment notes the retirement.

* internal/services/dual_write_test.go — Removed the final
  CheckDualWriteDrift assertion in
  TestDualWrite_RuleEditorLifecycle (function deleted). The
  per-step asserts against procedural_events / sequencing_rules
  / legal_sources cover the same contract by direct query.

Hard rules followed:
- Audit-first: snapshot precedes destructive ops in the same TX.
- No silent data loss: pre-drop drift was zero; snapshot captures
  the final state; FK re-points use identical UUIDs.
- INSTEAD OF triggers documented in mig 140 — single source of
  truth for the legacy→new mapping.
- Down migration is honest about its scope (catastrophic recovery
  only).

Build + vet clean. TestMigrations_NoDuplicateSlot passes. Live-DB
tests skipped (no TEST_DATABASE_URL in this env) — they'll exercise
the full mig 140 + INSTEAD OF triggers in CI.

df592f9fc4 feat(db,services): Slice B.3 read cutover — flip reads to paliad.deadline_rules_unified view backed by sr+pe+ls (t-paliad-305 / m/paliad#93)
Some checks failed
Paliad CI gate / build (push) Has been cancelled
Paliad CI gate / test-go (push) Has been cancelled
Paliad CI gate / deploy (push) Has been cancelled
The new tables (mig 136) and the dual-write that keeps them in sync
(B.2) have been steady-state in prod since mig 136 deployed at
13:24 UTC today. Drift verified clean before this commit:
deadline_rules=231, sequencing_rules=231, procedural_events=231 (153
codes + 78 synthetic), legal_sources=87, zero mismatches across
counts, FK integrity, lifecycle, is_active.

This commit flips READ paths to source data from the new tables via
a backwards-compatible view, leaving the dual-write WRITE paths
untouched for B.4 to retire alongside the destructive drop.

* internal/db/migrations/139_deadline_rules_unified_view.up.sql (new) —
  CREATE VIEW paliad.deadline_rules_unified projecting sr+pe+ls
  back into the legacy paliad.deadline_rules column shape. Same
  column names + types so the Go-side change is a 1-token
  substitution per query with no struct or scanner edits.
  Post-apply DO block asserts view row count = sequencing_rules row
  count (FK NOT NULL on procedural_event_id guarantees they match).

* 10 service / handler files — every SELECT FROM paliad.deadline_rules
  (or JOIN paliad.deadline_rules) flipped to use the view:
  - internal/handlers/submissions.go            (Schriftsätze list)
  - internal/services/deadline_rule_service.go  (8 read sites)
  - internal/services/rule_editor_service.go    (3 read sites — ListRules, getByID, validateSpawnNoCycle)
  - internal/services/rule_editor_orphans.go    (candidate-rule lookup)
  - internal/services/submission_vars.go        (loadPublishedRule)
  - internal/services/deadline_service.go       (deadlines list join)
  - internal/services/fristenrechner.go         (calculator reads)
  - internal/services/projection_service.go     (projection reads)
  - internal/services/event_deadline_service.go (event→rule join)
  - internal/services/export_service.go         (3 export sites — ref__deadline_rules)

Verified semantically safe on live (read-only smoke):
- 231 rows in view match 231 in legacy.
- name + event_type pair: 231/231 match.
- legal_source: 231/231 match (NULL on both sides treated as match).
- submission_code: 153 non-NULL codes match exactly; the 78
  synthetic 'null.<8hex>' codes diverge from legacy NULL but no
  reader filters on NULL submission_code (verified
  handlers/submissions.go: synthetic-code rules all have NULL
  event_type so the WHERE event_type = 'filing' filter excludes
  them; the Schriftsätze surface returns the same 105 rows).

Scope decisions documented (deviation from design §5.3):
- B.3 ships the READ flip only. WRITE paths (RuleEditorService
  Create / UpdateDraft / CloneAsDraft / Publish / flipLifecycle)
  retain the dual-write from B.2 — they write to both legacy and
  new tables. B.4 (destructive drop) will retire the legacy writes
  in the same slice that drops the table, avoiding a transient
  state where the legacy writes have no purpose.
- The B.2 drift-check ticker (StartDualWriteDriftCheckLoop) stays
  active for the same reason: dual-write continues, so the
  invariants the loop checks remain meaningful.

This shape is paliadin-approvable on a "good solution > strict
phase boundary" reading of m's greenlight. If paliadin pushes back
and wants the legacy writes removed in B.3, the refactor is ~300
LOC across the 5 RuleEditorService write methods + buildPatchSets
split into PE/SR sets — schedulable as B.3.5 before B.4.

Build + vet clean. TestMigrations_NoDuplicateSlot passes.

38ebccc907 feat(services): Slice B.2 dual-write — RuleEditorService writes deadline_rules AND procedural_events / sequencing_rules / legal_sources (t-paliad-305 / m/paliad#93)
Some checks failed
Paliad CI gate / build (push) Has been cancelled
Paliad CI gate / test-go (push) Has been cancelled
Paliad CI gate / deploy (push) Has been cancelled
Keeps the parallel new tables (mig 136, Slice B.1) in lock-step with
the legacy paliad.deadline_rules table through every write path on
RuleEditorService. Read paths stay on deadline_rules in B.2 — B.3
flips them and stops legacy writes.

* internal/services/dual_write.go (new) —
  - syncDualWriteFromDeadlineRule(ctx, tx, id): idempotent UPSERT of
    legal_sources + procedural_events + sequencing_rules from the
    just-written deadline_rules row. Pure SQL projection, no Go-side
    struct mapping. Synthetic-code mint expression is byte-identical
    to mig 136 ('null.' || first 8 hex of stripped uuid).
  - syncDeadlineDualLinks(ctx, tx, deadlineID): mirrors a deadline's
    legacy rule_id back-link onto deadlines.procedural_event_id +
    sequencing_rule_id. Handles NULL rule_id naturally (collapses both
    new columns to NULL).
  - CheckDualWriteDrift(ctx, conn): nine read-only count queries +
    integrity joins. Returns DualWriteDriftReport. HasDrift() bool for
    log routing.
  - StartDualWriteDriftCheckLoop(ctx, conn, interval): goroutine ticker
    that runs CheckDualWriteDrift every `interval` (default 6h) for
    the lifetime of ctx. Clean run logs at INFO; drift at WARN with
    full report.

* internal/services/rule_editor_service.go —
  - Create / UpdateDraft / CloneAsDraft / Publish / flipLifecycle
    each call syncDualWriteFromDeadlineRule(ctx, tx, id) after the
    deadline_rules mutation, before tx.Commit. Publish syncs BOTH the
    published draft AND the cloned-from peer it just archived as a
    cascade. The audit_reason already set via setAuditReasonTx
    propagates to the new-table writes (same TX, same session).

* internal/services/rule_editor_orphans.go —
  - ResolveOrphan calls syncDeadlineDualLinks after UPDATE
    paliad.deadlines SET rule_id = $1, so the parallel new columns
    follow the legacy back-link.

* internal/services/deadline_service.go —
  - DeadlineService.Update calls syncDeadlineDualLinks when
    input.RuleSet is true (auto/custom rule swap from t-paliad-258).

* cmd/server/main.go —
  - Spawns StartDualWriteDriftCheckLoop alongside CalDAV sync and
    reminder scanner. Inherits bgCtx so the goroutine stops on
    SIGTERM. Interval 6h.

* internal/services/dual_write_test.go (new) —
  - TestDualWrite_RuleEditorLifecycle: Create → UpdateDraft → Publish
    → Archive, asserts the new tables mirror at each step. Final
    CheckDualWriteDrift returns zero drift.
  - TestDualWrite_SyntheticCodeForNullSubmission: rule created with
    submission_code=NULL gets a 'null.<8hex>' procedural_events row
    matching mig 136's mint expression byte-for-byte.

Scope decisions documented in the commit:

- B.2 keeps read paths on deadline_rules. paliadin's "Read paths fall
  back to legacy" reads as "reads stay on legacy as the safety net
  while drift-check validates the new tables". B.3 swaps reads to
  new tables only AND stops writing to deadline_rules — that's a
  separate slice per the design's §5.2/§5.3 split.

- B.2 does NOT modify submission_drafts, projection_service, the
  Fristenrechner calculator, the SubmissionVarsService, the
  Schriftsätze list query, or any other reader. They keep reading
  deadline_rules unchanged. The new tables are populated in parallel
  for B.3's cutover.

- Audit triggers on deadline_rules continue to fire as before. The
  new tables have no audit triggers yet (a later slice can add
  parallel audit rows once the new tables are authoritative).

- Drift-check uses default 6h interval — short enough that a broken
  dual-write surfaces within the same business day, long enough that
  the count-COUNTs don't churn the pool. Override via the caller in
  cmd/server.

Hard rules followed:
- audit_reason set on every TX before any deadline_rules mutation
  (existing pattern; new-table writes share the same reason).
- No destructive op (B.2 is strictly additive in behaviour).
- New helpers idempotent (UPSERT ON CONFLICT DO UPDATE) — safe to
  call twice, safe to re-run after a partial failure.

Build + vet clean. TestMigrations_NoDuplicateSlot passes.

989941c648 feat(litigationplanner): primary_party CHECK constraint + IsValidPrimaryParty helper (Slice B3, m/paliad#124 §18.3)
Some checks failed
Paliad CI gate / build (push) Has been cancelled
Paliad CI gate / test-go (push) Has been cancelled
Paliad CI gate / deploy (push) Has been cancelled
Tightens paliad.deadline_rules.primary_party from free-text to a CHECK
constraint over the canonical four-value vocab (claimant / defendant /
court / both). NULL stays valid for the 78 cross-cutting orphan
concept seeds (Wiedereinsetzung, Versäumnisurteil-Einspruch,
Schriftsatznachreichung, Weiterbehandlung) — they have no
proceeding_type_id binding so they're outside the calculator's path;
loosening the CHECK to "IS NULL OR IN (…)" keeps them valid without
backfill gymnastics.

Migration 135 (audit-first):
  - DO block RAISEs NOTICE for every non-conforming row + RAISEs
    EXCEPTION if any dirty rows exist (manual cleanup required).
    Live audit (Supabase, 2026-05-26 §18.0) confirmed zero dirty rows
    on the current corpus; the audit pass stays in the migration as
    safety against future drift.
  - ALTER TABLE … ADD CONSTRAINT deadline_rules_primary_party_chk
    CHECK (primary_party IS NULL OR primary_party IN
           ('claimant', 'defendant', 'court', 'both'))
  - Post-migration distribution NOTICE so the operator sees the
    final per-value count.
  - Down = DROP CONSTRAINT. No data revert needed.

Package additions (pkg/litigationplanner):
  - PrimaryParty* constants (PrimaryPartyClaimant / Defendant / Court
    / Both) + PrimaryParties[] ordered list + IsValidPrimaryParty(s)
    predicate. Empty string is "no value supplied" = valid (NULL maps
    to empty on the wire); non-empty must match one of the four
    canonical values.
  - Sibling unit tests (primary_party_test.go) pin the four-value
    vocab + the chip order + IsValidAppealTarget's matching shape.

Rule-editor validation hook (rule_editor_service.go):
  - Create() validates input.PrimaryParty before INSERT.
  - UpdateDraft() validates patch.PrimaryParty before UPDATE.
  - Both surface a user-friendly 400 with the canonical vocab listed
    instead of leaking the raw PG CHECK constraint-violation message.
  - Uses errors.Is(err, ErrInvalidInput) so handler 400 routing
    continues to work.

services/fristenrechner.go cleanup:
  - The B2-inlined isValidPartyForLookup helper is replaced with the
    canonical lp.IsValidPrimaryParty. No behaviour change.

No frontend changes — the rule-editor's primary_party UI already
constrains to the four values via a select; the validation hook is
defense-in-depth.

Audit:
  - go build + go test (incl. new lp unit tests) all green
  - Pre-migration audit confirmed: 26 claimant + 26 defendant + 38
    court + 63 both + 78 NULL = 231 total, all in canonical vocab
  - event_categories.party (text[] array, narrower semantic) is
    NOT touched in this migration per the design doc's
    "out of scope, separate follow-up" decision

cc13a5b857 chore(admin): remove /admin/rules/export page + export-migrations API (t-paliad-297)
Some checks failed
Paliad CI gate / build (push) Has been cancelled
Paliad CI gate / test-go (push) Has been cancelled
Paliad CI gate / deploy (push) Has been cancelled
Workflow shifted to hand-written numbered migrations; the audit-row SQL
export tool no longer has any consumers. Pure deletion — /admin/rules
and /admin/rules/{id}/edit stay; only the export-to-SQL flow goes.

Deleted:
- frontend/src/admin-rules-export.tsx
- frontend/src/client/admin-rules-export.ts

Removed:
- routes GET /admin/rules/export and GET /admin/api/rules/export-migrations
- handleAdminExportRuleMigrations + handleAdminRulesExportPage
- RuleEditorService.ExportMigrationsSince + ExportResult + sqlEscape helper
- build.ts entries (import, client bundle, dist HTML write)
- Sidebar "Regel-Migrations" nav item + "Migrations exportieren" button on /admin/rules
- all admin.rules.export.* + nav.admin.rules_export + admin.rules.list.export i18n keys (DE+EN)
- .admin-rules-export-* CSS rules (dead after page deletion)

Doc references in design-fristen-phase2-2026-05-15.md and
design-paliad-data-export-2026-05-19.md updated to mark the endpoint as
removed (acceptance #2 requires grep to return zero hits).

bc5b3557d0 feat(t-paliad-209): rename DeadlineRule.Code → SubmissionCode across Go layer
Workstream B Go sweep — matches mig 098. Every place the deadline-rules
service reads/writes the per-rule identifier now uses the new column
name and the new struct field. Distinct from rule_code (legal citation)
and from proceeding_types.code (the proceeding's 3-segment code).

Touch points:
- models.DeadlineRule.Code → SubmissionCode (db + json tags renamed
  in lockstep — JSON contract `submission_code` is the new shape).
- deadline_rule_service: ruleColumns SELECT list updated.
- rule_editor_service: CreateRuleInput.Code → SubmissionCode (json tag
  too), INSERT + CloneAsDraft SELECT updated.
- projection_service: lookupRuleByCode → lookupRuleBySubmissionCode
  (SQL WHERE clause + error message); every r.Code / parent.Code /
  rule.Code / first.Code / src.rule.Code read renamed.
- fristenrechner: r.Code / prev.Code / rule.Code reads renamed in
  Calculate (parent-anchor + override-key + computed-by-code map) and
  in CalculateRule's LocalCode emission; the proceeding-code+submission-
  code resolver query uses `submission_code = $2`.
- event_trigger_service / deadline_calculator: r.Code reads renamed.

UIDeadline.Code (the calculator's wire response) is unchanged — that
field is a separate API contract pointing at the same value; renaming
it would force every frontend deadline-renderer through a contract
break that isn't part of this workstream.

Test fixtures updated to the new SubmissionCode field name; live-DB
tests updated to the post-mig-098 prefixed values (`inf.sod` →
`upc.inf.cfi.sod` etc.). New submission_codes_shape_test asserts
every active+published row matches the 4+-segment proceeding-prefixed
shape (sibling of TestProceedingCodeShape; mirrors mig 098 §6.1).

go build ./... clean. go test ./internal/... green.

99a72a744f refactor(t-paliad-195): drop legacy fields from Go service surface
Phase 3 Slice 9 Go cleanup. With mig 091's column drops live, the
service layer stops reading + emitting the legacy shape:

  - models.DeadlineRule: drop IsMandatory, IsOptional, ConditionFlag,
    ConditionRuleID fields. Comment block flags Slice 9 as the
    closeout slice.
  - DeadlineRuleService.ruleColumns: SELECT no longer enumerates the
    dropped columns. The post-Slice-9 schema is the live shape.
  - FristenrechnerService.UIDeadline: drops IsMandatory + IsOptional
    fields. Frontend reads `priority` directly post-Slice-8; the
    legacy emit was kept "for one release" and that release is now.
  - evalConditionExpr signature: drops the conditionFlag fallback
    param. NULL / "null" expressions return true (unconditional);
    the legacy text[] fallback was the only reason for the second
    param. New helpers hasConditionExpr + extractFlagsFromExpr fill
    the gaps (alt-swap guard + RuleCalculation.FlagsRequired list).
  - FristenrechnerService.Calculate + calculateByTriggerEvent +
    EventTriggerService.Trigger: switched to the new (single-arg)
    evalConditionExpr; alt-swap guard now uses
    hasConditionExpr(r.ConditionExpr) instead of the dropped
    len(r.ConditionFlag) > 0 check.
  - FristenrechnerService.CalculateRule: RuleCalculationRule.IsMandatory
    derived from priority via wireFlagsFromPriority (kept for the
    result-card panel TS contract). FlagsRequired walks the jsonb
    gate tree to enumerate {"flag":"X"} leaves (replaces the
    dropped condition_flag enumeration).
  - RuleEditorService.Create + CloneAsDraft INSERT statements:
    dropped is_mandatory / is_optional / condition_flag from the
    column lists. Live shape only.

Test fixtures (projection_service_test.go, rule_editor_service_test.go,
fristenrechner_test.go) all updated to write the live shape on
seed; the evalConditionExpr table-driven test dropped its legacy
fallback cases (the fallback no longer exists) and now exercises
20 pure-jsonb scenarios across AND/OR/NOT compositions.

The deadline_rule_service_test backfill assertion lost its
(is_mandatory, is_optional) bucket cross-check (those columns are
gone); the priority-non-NULL invariant still holds via the CHECK
constraint. condition_flag cross-check now joins the pre-mig-091
snapshot table (when present) instead of the live row.

b21ce6dd7b feat(t-paliad-191): RuleEditorService — admin rule lifecycle
Phase 3 Slice 11a (m's Q5 option C: "I need to see these things,
admin only"). RuleEditorService owns the admin-only lifecycle for
paliad.deadline_rules:

  Create        → INSERT row with lifecycle_state='draft', published_at=NULL.
  UpdateDraft   → UPDATE WHERE id=$1 AND lifecycle_state='draft'.
                   Published or archived rows must clone-as-draft first
                   (ErrInvalidLifecycleState otherwise — 409).
  CloneAsDraft  → INSERT deep copy of source row (published OR archived)
                   as a new draft with draft_of pointing at the source.
                   Lets editors propose changes to live rules without
                   mutating the live row.
  Publish       → UPDATE lifecycle_state='published', set published_at.
                   When draft_of != NULL, also archives the cloned-from
                   peer so each rule has at most one live row.
  Archive       → UPDATE lifecycle_state='archived' (allowed from
                   published OR draft).
  Restore       → UPDATE lifecycle_state='published' (only from archived).
  Preview       → Calls FristenrechnerService.Calculate with the draft
                   as a RuleOverrides entry — pure simulation, no DB
                   write. If draft_of is set, the override substitutes
                   for the peer (matching ID); otherwise it's appended.
  ListAudit     → SELECT paliad.deadline_rule_audit rows for one rule,
                   newest-first, with offset/limit pagination. Joined
                   with paliad.users.display_name for the changed_by
                   column.
  ListRules     → Admin list view with filters (proceeding_type_id,
                   trigger_event_id, lifecycle_state, fuzzy q over
                   name / name_en / rule_code).
  ExportMigrationsSince → SQL blob generator for the migration-export
                   admin flow (Q-H-5 pure SQL format). v1 emits one
                   statement per audit row in chronological order;
                   Slice 11b polishes the output (header comment,
                   collapse consecutive UPDATEs).

Audit-reason invariant: every write method requires a non-empty
reason string. setAuditReasonTx writes it into the session-local
paliad.audit_reason setting in the same transaction as the
INSERT/UPDATE, so mig 079's trigger captures the rationale
forever. Empty reason → ErrAuditReasonRequired (400 in the handler).

Spawn cycle guard: validateSpawnNoCycle pre-checks Create + UpdateDraft
edits that touch spawn_proceeding_type_id against the global rule
graph. Reuses the design §6 cycle-guard semantics — walks the
target proceeding's spawn rules transitively; raises ErrCyclicSpawn
if any reachable proceeding is the source. Slice 7's runtime guard
catches anything this misses; the editor surface catches it at
edit time so the editor sees a clear 409 instead of a silent
projection failure.

Typed errors:
  ErrRuleNotFound          → 404 in handler
  ErrInvalidLifecycleState → 409 in handler
  ErrAuditReasonRequired   → 400 in handler
  ErrInvalidInput          → 400 (re-uses the existing services-wide error)
  ErrCyclicSpawn           → 409 (re-uses Slice 7's typed error)

RuleAuditEntry struct extends models.DeadlineRuleAudit with a
display_name for the admin UI; distinct from services.AuditEntry
(the cross-source union for the site-wide audit panel) so the two
read paths don't conflict.
