- internal/geoip: Service over oschwald/geoip2-golang v2 with City db
enrichment (Country/Region/Subdivision/City) and a NopService
factory for environments without the mmdb file. Nil-safe Lookup
returns a zero geoip.Lookup on any failure path (nil receiver,
nil reader, empty/malformed IP, reader error, !rec.HasData).
- internal/geoip: unexported cityReader interface allows whitebox
fake-based unit testing without bundling a real .mmdb fixture;
extractLookup is a pure function for synthetic-record coverage.
- config: GeoIPConfig{Path} koanf section; GEOLITE_PATH env binding
matching compose.yml; default /data/GeoLite2-City.mmdb.
- deps: github.com/oschwald/geoip2-golang/v2 v2.1.0.
ASN/ASNOrg fields are reserved on geoip.Lookup but stay zero with a
City-only mmdb; populating them is a future-extension concern (ASN
db is not fetched by scripts/init.sh per design §12.5).
Phase 5 first commit. Adds the committed template.pdf binary blob plus
the pure-Go one-shot utility that produced it, matching the docx Phase
4 pattern (cmd/build<format>template/main.go excluded from production).
cmd/buildpdftemplate/main.go assembles a minimal PDF-1.4 by hand:
- Header: %PDF-1.4 + 4 high-bit bytes to mark as binary
- Object 1: Catalog → Pages root
- Object 2: Pages → single Kids ref + Count 1
- Object 3: Page with /AA << /O << /Type /Action /S /URI /URI (...) >> >>
where the URI value is the 76-char placeholder
HONEY_TRACK_URL_PADDED_TO_FIXED_WIDTH______________________________________
- xref table with computed byte offsets
- trailer + startxref + %%EOF
The placeholder is a direct dictionary value (NOT inside a stream), so
substitution can be a plain byte-replace at runtime without breaking the
cross-reference table — spec §9.4 line 1133. No FlateDecode anywhere.
pdfcpu (v0.12.1) is used for validation only — the builder calls
api.Validate before writing, and tests will call it again on substituted
output to confirm the PDF stays well-formed.
Verification at HEAD:
- 477-byte template.pdf
- sha256: 70c6359016ceb780539f8c4497991b98ff82201e35a38d36090d88856027e103
- Reproducible: rebuild produces byte-identical output
- grep -aob HONEY_TRACK_URL → one offset (240)
- file: PDF document, version 1.4, 1 page(s)
- api.Validate passes
go.mod adds pdfcpu as a direct dep with its transitive deps via go mod
tidy. golang.org/x/crypto returns to direct (pdfcpu uses it for AES
encryption support).
