Step 13: Korban Processor complete — 7 modules, 181 tests, all passing

- semichah: provenance tagging (6 sources, rejects empty/anonymous)
- shechitah: strip preamble, self-reference, hedging, markdown, sycophancy
- zerikah: extract Torah refs, Hebrew text, root analysis, insight markers
- haktarah: transform prose to Prolog propositions (verse/3, root/2, claim/2, connection/3)
- router: stateless routing — removed module-level _routing_log (kiyyor principle)
- model_interface: outbound Claude API via httpx (Construction §3.4, HTTPS only)
- hebrew_parser: nikkud/teamim stripping, consonant extraction, gematria, root identification

All 5 BUILD_KORBAN.md verification tests pass.
AGENTS.md: added structure_not_content.md to spec table, added Principle 6.
build_log.md: recorded session, broken tablets #18-20, design decisions.

Ka'asher tzivah Hashem et Moshe.
