The "Generieren" button on the project Schriftsätze tab posts to
/api/projects/{id}/submissions/{code}/generate. Pre-fix that handler
called `fetchHLPatentsStyleBytes` unconditionally and streamed the
result after a format-only .dotm→.docx convert — it never touched
`submissionTemplateRegistry` (added in t-paliad-241 for the draft
editor) and never ran the SubmissionRenderer merge. m's report on
m/paliad#84 ("the document generator still has no variables in the
template") was the lawyer-facing manifestation: HL Patents Style has
no {{…}} placeholders, so the downloaded .docx had nothing to
substitute and looked like a generic firm-style fixture.
The "Bearbeiten" path (/projects/{id}/submissions/{code}/draft) was
unaffected — it uses `resolveSubmissionTemplate` + the renderer
already, which is why the editor preview shows the 48 placeholders
resolved correctly. Only the one-click /generate side missed the
wire-up.
Fix:
- `internal/services/submission_draft_service.go` — add
`RenderProjectSubmission(ctx, userID, projectID, submissionCode,
templateBytes)` that wraps `vars.Build` + `renderer.Render` for the
no-saved-draft path. Returns the merged bytes plus the resolved
SubmissionVarsResult (rule, project, user, lang) so the handler can
derive filename + audit metadata without a second DB round-trip.
- `internal/handlers/submissions.go` — rewrite
`handleGenerateProjectSubmission` to resolve the template via
`resolveSubmissionTemplate` (per-firm slug → HL Patents Style
fallback, same as the editor draft) and run the new service method.
Visibility / rule-not-found semantics route through
`SubmissionVarsService` errors so the gate behavior matches every
other project endpoint. Removed `loadPublishedRuleByCode` and
`errRuleNotFound` — both were only used by the old handler.
- `scripts/gen-demo-submission-template/main.go` + the regenerated
`de.inf.lg.erwidg.docx` on mWorkRepo (HL/mWorkRepo @ 3e3e828f) now
exercise the bare `{{today}}` alias too. The demo template covers
every one of the 48 keys SubmissionVarsService can resolve (firm 2,
today 4, user 3, project 18, parties 6, rule 8, deadline 7).
The renderer is a no-op on placeholder substitution when the
fallback HL Patents Style is fetched (it has none) — but it still
runs the .dotm→.docx pre-pass via `ConvertDotmToDocx`, so the
non-per-firm code path streams a byte-for-byte equivalent download.
Build + vet + tests clean (go test ./internal/...; bun run build).
Authored a per-submission-code .docx template for `de.inf.lg.erwidg`
exercising every placeholder SubmissionVarsService resolves (45 keys
across firm/today/user/project/parties/rule/deadline namespaces), so
the Submissions draft editor has variables to substitute and the
sidebar/preview feature can be demonstrated end-to-end.
Pieces:
- `scripts/gen-demo-submission-template/` — one-shot Go authoring tool
that emits a minimal but Word-compatible .docx zip with a fake
Klageerwiderung skeleton in German. Each placeholder lives in its own
<w:r> run so the renderer's pass-1 (format-preserving) substitution
catches it without falling into the cross-run merge path. Output is
byte-reproducible (fixed mtime).
- `internal/handlers/files.go` — added `submissionTemplateRegistry`
(submission_code → fileRegistry slug) plus
`fetchSubmissionTemplateBytes` helper that reuses the Gitea proxy
cache infra. Registered one entry for `de.inf.lg.erwidg`. The file
itself was uploaded to mWorkRepo at
`6 - material/Templates/Word/Paliad/HLC/de.inf.lg.erwidg.docx`
(mWorkRepo commit 9633524).
- `internal/handlers/submission_drafts.go` —
`resolveSubmissionTemplate` now tries the per-code lookup first;
falls back to the universal HL Patents Style for any code that
doesn't have a per-firm template registered, matching the cronus
design fallback chain §8.
The existing HL Patents Style .dotm is untouched (still the universal
fallback and still the source for the format-only /generate path).
Future per-submission templates register one fileRegistry entry +
one submissionTemplateRegistry row.
