feat(fristenrechner): sort post-trigger events by duration ASC within parent group (t-paliad-296)

Optional events anchored on the same trigger (e.g. the four
post-Entscheidung rules in upc.inf.cfi) used to render in catalog
sequence_order, so a 2-month rule (R.118.4 Folgeentscheidungen)
would precede a 1-month rule (R.151 Kostenentscheidung) chained
off the same decision. Now the calculator does a post-evaluation
permutation pass that sorts consecutive same-parent rows by
duration ascending — days < weeks < months < years, ties broken
by duration_value then submission_code.

Different trigger groups keep their proceeding-sequence position
— the walk only ever permutes rows that already share a parent.
Root rules (no parent) are never sorted against each other.
Court-set / conditional rows whose date isn't in the duration
ladder sort LAST within their group.

Verified order against m's report: R.151 cost_app + R.353
rectification (1-month tier) now render before R.220.1
appeal_spawn + R.118.4 cons_orders (2-month tier).

+# Paliad CI gate (t-paliad-282 / m/paliad#114).
+#
+# Single workflow, two purposes:
+#
+#   - On every push: gate tier — build + unit + migration smoke. Red gate
+#     means no further work and (on main) no deploy.
+#   - On push to main with gate green: deploy step — calls the Dokploy
+#     compose-deploy API for paliad's compose Zx147ycurfYagKRl_Zzyo, then
+#     polls /health/ready until the new container reports 200.
+#
+# The deploy step REPLACES the previous Gitea-push → Dokploy webhook path
+# (per m's Q11.4 pick: soft-launch with both alive for ~1 week, then
+# disable the Dokploy auto-deploy toggle). Soft-launch leaves Dokploy's
+# autoDeploy=true intact today — the workflow's deploy step is additive
+# and idempotent (Dokploy's deploy is itself idempotent).
+#
+# Catches the three failure classes from 2026-05-25:
+#
+#   - brunel slot collision (~13:20) — TestMigrations_NoDuplicateSlot,
+#     pure unit, no DB needed.
+#   - hermes dropped-col refs (~16:05) — TestBootSmoke, applies all NEW
+#     migrations (those not in the snapshot) end-to-end against a
+#     scratch DB restored from internal/db/testdata/prod-snapshot.sql.
+#   - mig 129 42501 ownership (~14:56→) — TestMigrations_EndToEndAsAppRole,
+#     applies new migrations as the prod-shaped `postgres` role (which
+#     is NOT a superuser on supabase/postgres — same shape as
+#     youpc-supabase prod, see internal/db/testdata/README.md).
+#
+# Snapshot approach: dump paliad schema + applied_migrations rows from
+# prod, commit them. CI restores → ApplyMigrations sees existing migs as
+# applied, only runs NEW migs (the ones this PR adds). This sidesteps the
+# fresh-DB idempotence requirement on historical migrations (some of
+# which use raw COMMIT or pre-installed extensions and can't be replayed
+# from scratch). To refresh: `make refresh-snapshot`.

+# CI/CD runner setup — paliad
+
+**Companion to:** `docs/design-cicd-pre-deploy-gate-2026-05-25.md` (Slice A, t-paliad-282 / m/paliad#114)
+**Date:** 2026-05-25
+**Audience:** mlake / mriver admin (m or head)
+
+Slice A's `.gitea/workflows/test.yaml` requires (a) at least one online Gitea Actions runner and (b) a Dokploy API token wired as a repo secret. Both are one-time setup actions that paliad's source tree cannot perform itself — they live on infra-side. This doc lists them so the workflow can go green on its first run.
+
+---
+
+## 0. Pre-flight: what already exists
+
+Verified live (2026-05-25 cronus inventor shift):
+
+- Gitea 1.24.4 on `mgit.msbls.de`, `has_actions: true` on `m/paliad`.
+- `/api/v1/admin/actions/runners` reports **2 runners** registered. They are likely the shared runners used by `m/mGreen` and `m/mGeo` (both have `.gitea/workflows/deploy.yml` with `runs-on: self-hosted`).
+- `m/paliad/actions/tasks` reports `total_count=0` — paliad has never run a workflow yet.
+
+The existing runners may already be capable of running paliad's workflow without further setup. The verification step (§3) below tells you whether they are.
+
+---
+
+## 1. Runner placement decision (m's Q11.1)
+
+m's pick: **mriver**.
+
+Rationale: mriver hosts the mai worker fleet but workers spend most of their time waiting on Anthropic. mlake's Dokploy + Swarm workload is more contended. A new runner on mriver adds the least pressure to either box.
+
+If mriver is offline or saturated when CI first fires, fall back to the existing mlake-side runners (they're already registered; no provisioning needed).
+
+---
+
+## 2. One-time setup (admin steps)

+chmod +x /usr/local/bin/act_runner
+
+# 2. Get a runner registration token. In the Gitea UI:

+#    (or org-scope: /m/paliad/settings/actions/runners)
+# Copy the token.
+

+```
+
+**Why `ubuntu-latest:docker://node:20-bookworm` for the label?** Gitea Actions' `runs-on: ubuntu-latest` resolves via the runner's label map. Mapping it to a Docker image gives the workflow a sandbox with Docker available — required for our Postgres service container in `test.yaml`. mriver should have Docker (for `paliadin-shim`); if not, install it.
+
+### 2.2 Register the Dokploy API token as a repo secret
+
+The workflow's `deploy` job needs `secrets.DOKPLOY_TOKEN`. Use the existing project-wide Dokploy API key (the one stored in `~/.claude/skills/mai-dokploy/SKILL.md`).
+
+In the Gitea UI:
+- Navigate to `https://mgit.msbls.de/m/paliad/settings/actions/secrets`
+- Click "Add secret"
+  - Name: `DOKPLOY_TOKEN`
+  - Value: `mai-ottosSyRHMhmLhhhXaCbKzbqKBuSqzqEtmKDOPelPCeimTaYsbmaVslVyEgJZGCIxVdz`
+
+Or via API (mAi identity):
+```bash
+curl --netrc-file ~/.netrc-mai -sS -X POST \
+  -H "Content-Type: application/json" \
+  https://mgit.msbls.de/api/v1/repos/m/paliad/actions/secrets/DOKPLOY_TOKEN \
+  -d '{"data":"mai-ottosSyRHMhmLhhhXaCbKzbqKBuSqzqEtmKDOPelPCeimTaYsbmaVslVyEgJZGCIxVdz"}'
+```
+
+(Requires repo-owner permission. If mAi lacks it, m runs it.)
+
+---
+
+## 3. Verify the runner sees the workflow
+
+After (2.1) + (2.2):
+
+```bash
+# Push the Slice A branch (the one this doc lives on)
+git push origin mai/cronus/coder-cicd-slice-a
+
+# Confirm the runner picked up the job
+curl --netrc-file ~/.netrc-mai -sS \
+  "https://mgit.msbls.de/api/v1/repos/m/paliad/actions/tasks?limit=5" | jq '.'
+```
+
+A new task per job should appear (build, test-go). If `total_count` stays 0, the runner labels don't match the workflow's `runs-on`. Re-register with `--labels ubuntu-latest` (no docker:// suffix) and the existing runners on mlake will pick it up via shell mode.
+
+---
+
+## 4. Soft-launch (m's Q11.4)
+
+m's pick: **keep both Dokploy auto-deploy and the workflow's deploy step alive for ~1 week. After ≥5 successful green deploys via the workflow, disable Dokploy's autoDeploy in the Dokploy UI for the paliad compose.**
+
+While both are live, every push to main fires:
+1. Dokploy webhook (existing path) → deploys immediately, no gate.
+2. Gitea workflow → on green, ALSO calls `compose.deploy`.
+
+The second call is idempotent — if Dokploy already deployed the same commit, this is a no-op. The workflow's value during soft-launch is the **gate signal**: a red workflow on a green main = the bad migration shipped via the unguarded webhook and broke prod, and the workflow is shouting about it.
+
+After confidence builds:
+1. In the Dokploy UI, navigate to the paliad compose → Settings.
+2. Toggle "Auto Deploy" off.
+3. Save.
+
+From this point, the only path to deploy is the workflow's deploy job. Red workflow = no deploy.
+
+---
+
+## 5. What Slice A catches today — and what it doesn't
+
+After this branch (`mai/cronus/coder-cicd-slice-a`) merges to main:
+
+### Catches (active in CI)
+
+- **Build breakage** — `go build`, `go vet`, `bun run build`. Red gate, no deploy.
+- **Slot collisions** — `TestMigrations_NoDuplicateSlot` runs without a DB. A PR adding migration N when version N already exists fails at gate time. This is the brunel-class catch (m/paliad#114 ~13:20 outage).
+- **New-migration shape errors (hermes class)** — `TestBootSmoke` runs `ApplyMigrations` against the snapshot-restored DB. New migs from this PR get applied for real; any column/relation/syntax error fails the gate before merge.
+- **New-migration ownership errors (mig 129 42501 class)** — `TestMigrations_EndToEndAsAppRole` runs `ApplyMigrations` connected as `postgres` (NON-superuser on `supabase/postgres:15.8.1.060`, same role topology as youpc-supabase prod). Any migration that assumes supabase_admin privilege fails with the same `42501 must be owner` error class that took paliad.de offline on 2026-05-25.
+- **Readiness probe regressions** — `TestHealthReady_Live` confirms `/health/ready` returns 200 against a live pool, 503 against a nil pool.
+- **Pure-Go test regressions** — `go test ./internal/... ./cmd/...` runs without `TEST_DATABASE_URL` (live-DB service tests skip the same way they do on a developer laptop without a scratch DB).
+
+### Mechanism — the snapshot approach
+
+CI's scratch DB starts from a `pg_dump` of youpc-supabase paliad schema +
+`paliad.applied_migrations` rows, committed to `internal/db/testdata/prod-snapshot.sql`. After restore, the scratch DB is at "paliad HEAD of snapshot" and `ApplyMigrations` sees only this PR's new migrations as pending.
+
+This sidesteps the fresh-DB idempotence problem: several historical migrations (notably mig 037's missing `CREATE EXTENSION pg_trgm`, mig 051's inner `COMMIT;`) can't be replayed from scratch against `supabase/postgres:15.8.1.060`. The snapshot pins everything that's already applied in prod and lets CI focus on what's new — which is what we actually care about for outage prevention.
+
+Snapshot refresh: `make refresh-snapshot` with `PALIAD_PROD_DATABASE_URL` set (see `internal/db/testdata/README.md`).
+
+### Known gap — live-DB service tests don't run in CI
+
+`internal/services/*_test.go` tests with `TEST_DATABASE_URL` set fail against `supabase/postgres:15.8.1.060` with `42P08 inconsistent types deduced for parameter` errors on some INSERT bind paths. The same tests pass against youpc-supabase prod. Cause is unconfirmed — likely subtle differences in type inference between the dockerized image and the prod cluster's configuration. CI today runs `go test ./...` without `TEST_DATABASE_URL` so these tests skip. Not blocking outage prevention; tracked as a follow-up for the post-Slice-A coder.
+
+### Migration cleanup also bundled in this PR
+
+Two surgical migration improvements that surfaced during snapshot debugging — kept here because they're small and harmless:
+
+- **mig 024 + 027** — `ALTER INDEX` / `ALTER POLICY` exception handlers now catch `undefined_object` OR `undefined_table` OR `duplicate_object`. Old handler caught only `undefined_object`; Postgres raises `undefined_table` when the source object never existed and `duplicate_object` when the destination already exists. The expanded handler makes the migrations truly idempotent across the three plausible states: source-still-German (rename succeeds), already-renamed (catches duplicate_object), and fresh-DB-never-had-German (catches undefined_table).
+
+Other migration history bugs (mig 037 missing pg_trgm, mig 051 inner COMMIT) are tracked as a separate cleanup task — not blocking, because the snapshot bypasses them.
+
+### Verification checklist (after Slice A merges)
+
+1. **Workflow green on its first PR run?** Check `/m/paliad/actions`. If not, fix before merging.
+2. **Dokploy `compose.deploy` call succeeds?** The workflow's `deploy` job logs the POST response. A successful response is a Dokploy job ID; a 4xx is an auth or compose-id problem.
+3. **`/health/ready` returns 200 within 5 minutes after a green deploy?** The workflow polls this. If it times out, the migration may have failed silently inside the new container — check `docker logs --tail 50 compose-transmit-multi-byte-driver-v7jth9-web-1` on mlake.
+4. **Reproduce the slot-collision catch locally:** rename `131_…up.sql` to `129_…` (duplicate slot) → workflow MUST fail at `Migration coordination check`. Revert before pushing.
+5. **Reproduce the role-split catch locally:** add a no-op migration `132_test_supersedes.up.sql` containing `REINDEX SYSTEM paliad_scratch;` (requires superuser). Workflow MUST fail at `Migration end-to-end (deploy role)`. Revert before pushing.
+
+---
+
+## 6. Future polish (Slice D, m's Q4 R-pick)
+
+`mai-test` post-merge shift: once Slice A is stable, wire a Gitea webhook on push-to-main that fires `/mai-test` as a follow-up shift. It runs the broader smoke + integration suite and posts results as a Gitea commit status. Not blocking; the gate doesn't depend on it.
+
+Implementation belongs in `m/mAi` (the mai webhook handler), not in paliad. Out of scope for Slice A.

+--
+-- m's 2026-05-25 report: the upc.dmgs.cfi proceeding stops at the
+-- last party submission (rejoin) — no interim conference, no oral
+-- hearing, no decision row, no appeal-spawn. The upc.pi.cfi
+-- proceeding has its decision row (`pi.order`) but no spawn into
+-- the appeal tree. Both gaps prevent the Verfahrensablauf timeline
+-- from rendering the court phase plus any downstream appeal sub-
+-- tree that atlas's #96 spawn-rendering mechanism is otherwise
+-- ready to surface.
+--
+-- Two sections in one migration (slot 133 — knuth on 132, paliadin
+-- coordinated):
+--
+--   A. UPC Damages tree-end rows (#117)
+--      A1  upc.dmgs.cfi.interim       UPC RoP R.105   court-set hearing

+-- Source citations:
+--   * docs/research-deadlines-completeness-2026-05-25.md
+--       — §2.1 (upc.dmgs.cfi has only 4 rules: R.131.2 / R.137.2 / R.139)
+--       — §D Damages table (R.144 tree-end row missing — listed
+--         in Tier 4 as "cosmetic", upgraded to Tier-0 by m's
+--         report once the wider follow-up gap was understood)
+--   * docs/audit-upc-rop-deadlines-2026-05-08.md §D row R.144,
+--     §F R.220.1(a) / R.224.1(a) (verified verbatim in youpc DB
+--     under law_type=UPCRoP).
+--   * UPC Rules of Procedure (consolidated):
+--       R.105 — Interim conference (court fixes after written
+--         procedure closes; same structural shape as the inf
+--         interim conference, already modelled as `upc.inf.cfi.interim`).
+--       R.118 — Decision after oral hearing; general rule for
+--         deciding panels.
+--       R.250 — Determination of damages decision; damages-
+--         specific decision rule (chains R.144 indication →
+--         damages award).
+--       R.144 — Final decision on damages quantum (tree-end
+--         anchor for §A3).
+--       R.220.1(a) — Appeal lies from any final decision /
+--         decision disposing of the case at first instance.
+--         A PI order under R.211 disposes of the urgent question
+--         and is therefore appealable on the main 2-month track
+--         (not the 15-day order track of R.220.1(c), which covers
+--         case-management and procedural orders requiring leave).
+--         Curie's §F table confirms the main-track wiring for
+--         decisions on merits / disposing orders.
+--       R.224.1(a) — Statement of Appeal within 2 months of
+--         service of the final decision; the deadline-notes text
+--         mirrors mig 095's inf.appeal_spawn / rev.appeal_spawn.
+--       R.224.2(a) — Statement of grounds within 4 months
+--         (separate deadline in the spawned upc.apl.merits
+--         proceeding; already present as upc.apl.merits.grounds).
+--
+-- Shape decisions (mirroring mig 012 / mig 095 conventions):
+--   * Court-set rows (interim / oral / decision) carry
+--     primary_party='court', event_type='hearing'|'decision',
+--     duration_value=0, is_court_set=true, parent_id=NULL,
+--     concept_id reuses the shared concepts already wired for
+--     upc.inf.cfi (interim-conference / oral-hearing / decision).
+--   * Spawn rows carry primary_party='both', is_spawn=true,
+--     spawn_proceeding_type_id=11 (upc.apl.merits), spawn_label
+--     identical to the merits spawn already in production. The
+--     spawn row's parent_id is the spawning decision/order row
+--     (so the audit log carries the trigger link).
+--   * No condition_expr — m's F2.3 decision recorded in mig 095
+--     §3: "the appeal deadline should always be triggered by a
+--     decision … appeal is always a possibility." Visibility
+--     filtering on the frontend hides appeals on projects where
+--     no appeal is contemplated.
+--   * sequence_order numbering follows the inf convention
+--     (40=interim, 50=oral, 60=decision, 80=appeal_spawn) so the
+--     Verfahrensablauf timeline orders consistently across
+--     proceedings. For PI the existing pi.order sits at
+--     sequence_order=3; the appeal_spawn lands at 10 (clear of
+--     the writ phase, room for future court-phase rows).
+--
+-- Idempotency: every INSERT is gated by `WHERE NOT EXISTS (… same
+-- submission_code, proceeding_type_id, lifecycle_state)`. Re-apply
+-- against an already-migrated DB inserts zero rows and the audit
+-- log carries no duplicate entries.
+--
+-- audit_reason set_config required at the top — the mig 079 trigger
+-- on paliad.deadline_rules raises EXCEPTION 'audit reason required'

+# `internal/db/testdata/` — CI snapshot
+
+## `prod-snapshot.sql`
+
+Schema-only `pg_dump` of paliad's prod DB (youpc-supabase paliad schema)
+plus the rows of `paliad.applied_migrations` that match this branch's
+on-disk migration set.
+
+**Purpose.** Lets CI's migration smoke (`.gitea/workflows/test.yaml`)
+restore a Postgres scratch DB to "paliad at HEAD-of-snapshot" without
+having to replay 131 migrations from scratch. ApplyMigrations on the
+restored DB sees the applied set and only runs whatever NEW migrations
+this PR adds — exactly the integration shape we want to test, and the
+same shape prod sees on every deploy.
+
+**Why a snapshot at all.** Running ApplyMigrations from scratch against a
+fresh `supabase/postgres:15.8.1.060` surfaces multiple fresh-DB
+idempotence bugs in historical migrations (raw `COMMIT;` in mig 051,
+missing `CREATE EXTENSION pg_trgm` for mig 037, ALTER POLICY
+exception-handler gaps in mig 024/027 — the last is fixed in this PR).
+Fixing them all is a separate cleanup. The snapshot sidesteps them by
+starting CI from a state where every historical migration is already
+applied as it was in prod.
+
+**Schema scope.** `--schema=paliad` only. Auth schema comes baked into
+`supabase/postgres`; CI's setup step installs `pg_trgm` before restoring.
+
+**Ownership.** `--no-owner --no-privileges` keeps the dump portable
+across role topologies (CI's supabase_admin / postgres / authenticated /
+anon don't have to match prod's exact role layout). The role-split smoke
+relies on `postgres` being a non-superuser, which is true on
+supabase/postgres by default.
+
+**Refresh.** Run `make refresh-snapshot` with `PALIAD_PROD_DATABASE_URL`
+set to a Postgres URL with `pg_dump` rights on youpc-supabase. The
+target appends data rows for `paliad.applied_migrations`, strips
+`\restrict` / `\unrestrict` commands (pg 16 dump → pg 15 restore), and
+filters out applied-migrations rows for versions beyond the branch's
+local max. The CI workflow consumes the resulting file verbatim.
+
+**Verify a refresh.** Boot a local scratch:
+
+```bash
+docker run -d --rm --name paliad-snap \
+  -e POSTGRES_PASSWORD=ci -e POSTGRES_DB=paliad_scratch \
+  -p 15433:5432 supabase/postgres:15.8.1.060
+sleep 5
+docker exec -e PGPASSWORD=ci paliad-snap psql -h localhost -U supabase_admin -d paliad_scratch \
+  -c "GRANT CREATE ON DATABASE paliad_scratch TO postgres;" \
+  -c "CREATE EXTENSION IF NOT EXISTS pg_trgm;"
+cat internal/db/testdata/prod-snapshot.sql | docker exec -i -e PGPASSWORD=ci paliad-snap \
+  psql -h localhost -U postgres -d paliad_scratch -v ON_ERROR_STOP=1
+TEST_DATABASE_URL="postgres://postgres:ci@localhost:15433/paliad_scratch?sslmode=disable" \
+TEST_APP_DATABASE_URL="postgres://postgres:ci@localhost:15433/paliad_scratch?sslmode=disable" \
+  go test -count=1 -run 'TestMigrations|TestBootSmoke|TestHealthReady_Live' ./internal/db/ ./cmd/server/
+docker stop paliad-snap
+```
+
+All four named tests must pass. If any fails after a refresh,
+investigate before merging — usually because a new migration was added
+to prod that this branch doesn't have on disk yet.
+
+**Why is the snapshot not gzipped?** Small enough (~200 KB) that the
+diff stays human-readable in `git diff` reviews. If it crosses ~1 MB,
+gzip + decompress-on-restore in CI.
+
+**Privacy.** Schema-only dump, no row data from any paliad table (except
+`paliad.applied_migrations`, which contains migration filenames +
+checksums — public info already in the repo).
