A submission draft can now render from an uploaded docforge template
instead of a legacy Gitea base. DB-VERIFIED against TEST_DATABASE_URL (the
head greenlit option C) before commit — not just compiled.
Schema: migration 159 adds submission_drafts.template_version_id (nullable,
FK template_versions ON DELETE SET NULL) — the snapshot pin (PRD A3). A
later template edit creates a new version; the pinned draft keeps rendering
its version.
Draft service: TemplateVersionID on the model + draftColumns + the JOIN
list + DraftPatch (two-level pointer like base_id) + Update SET. Column-sync
verified live (Create_seeds_section_rows + the new pin test both pass).
Export/preview (handlers): a template-version path checked FIRST — load the
carrier via TemplateStore.GetVersion, render via the existing Export/
RenderPreview (the carrier already carries {{slots}}; no Composer/sections
needed). Falls through to base_id / v1 if the pin is missing. Both preview
sites + the view assembly branch on it.
Store: TemplateMeta.VersionID exposes the current version's row id (slice-4
gap — a consumer needs it to pin); populated in List/Get/GetVersion + the
authoring JSON. New GET /api/templates (authenticated, firm-filtered) is the
picker list any lawyer reads; admin authoring endpoints stay gated.
Frontend: the submission editor's base picker now offers uploaded templates
as a 'tpl:<version_id>' optgroup; selecting one PATCHes template_version_id
(clearing base_id) and vice versa — mutually exclusive render paths.
Live test (submission_draft_template_live_test.go, gated): pin round-trips
Update→Get, the uploaded carrier renders ({{firm.name}}→HLC via Export), and
clearing nulls it — all PASS against real Postgres.
Verification: go build/vet/gofmt clean; bun build + bun test 274/274; slice-7
+ slice-4 store + draft/composer live tests PASS against TEST_DATABASE_URL.
Pre-existing env failures (approval/projection seed $1-type quirk,
migration136 stale deadline_rules table) are unrelated — confirmed my branch
touches none of that code.
