Nambli 1.0.0 — approved upstream release, 2026-10-07

STATUS
Submitted: https://github.com/google/fonts/issues/11082
Merged design review: https://github.com/Tor-Production/nambli-font/pull/1
Yurii Tor's Individual CLA was verified as on file on 2026-10-07.
Google Fonts has not accepted or published Nambli. Yurii Tor approved the
final designs and authorized publication on 2026-10-07. Upstream release
v1.0.0 uses font version 1.000 and the exact validated font files.

DESIGN REFINEMENT
All twelve styles contain 970 encoded characters and 998 glyphs. Compared with
the previous candidate (671f777), 21 forms per style changed: @; P/p with hook;
T/t with hook; T/r/R retroflex tails; g/h/H/W/w with hook; reversed ezh;
crossed-tail j, dotless j and J; Latin beta capitals/lowercase; i-ogonek and
its dotless alternate. Review all 252 cards in:
  refinement/Nambli-Refinement-Review.html
The complete comparison with public v0.7.4 remains in:
  review/Nambli-Technical-Review.html

@ uses the approved a at uniform 0.64 scale. Its circular bowl is now centered
on the outer loop, with a curvature-continuous right return. Saved-font center
error is at most 0.2881 font units; the pre-quantization a-counter XOR is zero.
U+01B9 reuses the existing U+025B outline, retaining its distinct Unicode mapping.
The 36 crossed-tail counters deviate from circles by at most 0.867 units after
TTF rounding. Hook joins are continuous; selected italic backtracking segments
found by final QA were repaired locally. TOP mark anchors follow the revised
stems and heights; other anchor classes and unrelated layout remain unchanged.

PRESERVATION
All 872 release Unicode mappings and 887 release metrics per face remain.
10,612 of 10,644 release glyph instances retain exact normalized geometry.
The 32 exceptions are @ and i-ogonek in all twelve styles, plus heavy ɬ/Ɬ
aperture repairs in four styles. The refinement changed 21 of 998 forms per
face; every other outline remains identical to candidate 671f777.
See approved-outline-preservation.json and refinement-integration.json.

PRODUCTION BUILD
The editable UFOs build independently through Fontmake 3.12.1/ufo2ft 3.9.1.
11,976 exact glyph comparisons and 105,696 shaping comparisons pass. Two
builds produce identical SHA-256 hashes for all 24 TTF/WOFF2 files. Reference
binaries are validation inputs only; feature source, kerning and STAT are
editable. See production-build-validation.json and sources/BUILDING.md.
Supplementary OTFs carry the final repaired contours and matching layout;
unaffected CFF contours are unchanged. The independent build still produces
TTF/WOFF2, not OTF; see supplementary-otf-validation.json.

FINAL QA
Fontspector 1.8.0, all twelve final TTFs, complete googlefonts profile,
network enabled, no exclusions: 1127 PASS, 134 WARN, 704 SKIP, 80 INFO, 0 FAIL, 0 ERROR, 0 FATAL.
All TTF and OFL hashes are unchanged by QA. Offline results are recorded
separately; network checks are skipped only in that explicitly offline run.
See fontspector-summary.json and fontspector-network-summary.json.
Real HarfBuzz tests cover soft-dotted forms, language substitutions and mark
stacking; supplementary OTF and editable feature tables match exactly.
Pairwise contour checks cover 72 R-tail and 924 hook combinations.
They were repeated on the final build; see refinement-final-pair-validation.json.

GOOGLE FONTS REVIEW STILL PENDING
Author review is complete. Remaining Fontspector WARN/SKIP messages remain
available in the reports; zero FAIL and upstream publication do not establish
Google Fonts acceptance. Curatorial and specialist-language review remain
with the Google Fonts onboarding process.
