Backend: mig 110/111 (will be renumbered after merging main),
validators + helpers widened, BuildProjectCode helper + projection
populator wired into List/GetByID/ListAncestors/GetTree/CCR. All
internal Go tests pass.
Frontend: ProjectFormFields conditional render — opponent_code on
litigation, our_side renamed to Client Role on case with grouped
optgroups. i18n keys for both DE and EN. fristenrechner perspective
mapping widened. project-form.ts payload reader/writer + showFieldsForType
toggle for new litigation block.
Migration slots about to be bumped (mig 110 was claimed by euler's
project_type_other on main).
UPC briefs parenthesise the patent kind code ("EP 1 234 567 (B1)")
where the DE convention runs it inline ("EP 1 234 567 B1"). Slice 2
adds the {{project.patent_number_upc}} placeholder for the new UPC
templates (Q-S2-4 locked at 'all yes' on 2026-05-20).
Pure function alongside legalSourcePretty. Trailing single-letter +
single-digit kind code regex; everything else preserved. Pass-through
on unrecognised shapes — the lawyer's draft never sees a number worse
than the source value.
Wired into addProjectVars so every render exposes both forms
({{project.patent_number}} and {{project.patent_number_upc}}). UPC
templates pull the parenthesised form; DE templates ignore it.
8 test cases (more than the 6 in the brief) covering:
- EP B1 / EP A1 — common case
- DE national with kind code
- No kind code → pass-through
- Whitespace trimming
- Empty input
- WO publication number (no kind-code shape) → pass-through
- Two-digit kind code (B12) → pass-through (intentional — real EP
kind codes are single-letter + single-digit)
No schema change, no migration, no var-bag namespace additions
beyond the one new placeholder.
Pure-Go {{path.dot.notation}} placeholder engine + unit tests
(t-paliad-215, design docs/design-submission-generator-2026-05-19.md
§6). Chosen over github.com/lukasjarosch/go-docx because that library
treats sibling placeholders inside one <w:t> run as nested and
refuses to replace them — patent submissions routinely carry multiple
placeholders per paragraph (party blocks especially), so the library
is a non-starter.
Two-pass strategy preserves run-level formatting on the common path:
1. Pass 1: regex replace inside each <w:t>…</w:t> independently —
no format loss for the 99% case where placeholders are intact.
2. Pass 2: paragraph-level merge for paragraphs that still contain
orphan "{{" or "}}" markers (Word fragmented the placeholder
across runs).
Missing placeholders render [KEIN WERT: <key>] / [NO VALUE: <key>]
markers so the lawyer sees the gap in Word rather than getting a 400.
Tests cover: single-run, multi-per-run (the go-docx failure mode),
cross-run merge, missing-marker (DE+EN), XML escaping of special
chars, non-document zip entries preserved, placeholder regex
grammar.
