SPDX-License-Identifier: GPL-3.0-or-later" headers to the project-authored sources (clectio.c with the full grant, plus mktext.c and bin2h.c), replacing their old public-domain notes. - puff.c/.h keep Mark Adler's public-domain notice unchanged: third-party, not ours to relicense, and public domain is GPL-compatible. - README and man page LICENSE sections updated to GPL-3.0-or-later, noting puff's PD status; the scripture-text carve-out (Vulgate public domain, corpora under their own terms) is preserved.

Text blob 671 KB -> 492 KB (OF), 164 KB -> 132 KB (EF), 2.7x. - Build with -no-pie: clectio is a local CLI reading static embedded data with no attack surface, so it needs no PIE/ASLR. The linker then bakes the string- table pointers in at link time instead of emitting ~57 KB of runtime relocations. Net: OF 879 -> 662 KB, EF 266 -> 214 KB. Verified byte-identical to lectio. The default build still needs only a compiler + libc; a CORPUS= rebuild now also needs gzip. lz.h removed.

The Vulgate source has occasional double spaces that were leaking into the output. - Regenerated gen/ with the hermetic, alias-fixed clectio-gen: the generator no longer picks up the user's stale books.ini (which had silently dropped ~30 EF Ember-day lessons, e.g. St Lawrence-common Sir 45, Osee/Hosea 14, 2 Esdras/Nehemiah 8). Full range 2025-2054 now has 0 dropped readings. Verified vs lectio: OF and EF 2026 are byte-identical (day names + verse text, 0 mismatches); range boundaries 2025-01-01 / 2054-12-31 match; ASAN + UBSAN clean over leap days, boundaries and edge cases; bad input never crashes. Shipped total 1.28 MiB.

The calendar, reading citations and scripture text are all compiled in; the whole shipped package fits on a 1.44 MB floppy (~1.29 MiB) and the binary is ~0.9 MB (OF) / ~0.3 MB (EF). - suckless config.h: FORM_OF/FORM_EF, SIGLA_ENGLISH/SIGLA_LATIN, COLOR. - Bring your own Bible: `make CORPUS=mybible.tsv` recompiles with any Vulgate-numbered 6-column TSV; only the ~12k cited verses are embedded. - The hard liturgical logic stays in lectio (Go, oracle-validated); its clectio-gen emits the corpus-independent tables in gen/. The scripture text is LZSS-packed (lz.h) to fit; mktext/bin2h resolve+embed it at build time. - Verified byte-identical to lectio's readings; day names match 157/157 over a 3-year sample. Default text: public-domain Latin Vulgate. ISC-licensed. Claude-Session: https://claude.ai/code/session_01S1CD1u3tgSS4xNu6WHfp5a
