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).
