Retrofit the Phi primer against current canon

[dcellison]

Summary

This completes the SEM-09D contextual retrofit of all twenty-seven Markdown files in primer/. It preserves the graded household story while bringing the course into line with the completed lexicon, current canon, and the modifier-first invariant.

The pass corrects the treatment of careful pronunciation, directives, possibility and necessity, habitual aspect, proper designations, quotation, counterfactual conditions, and evidential particles. In particular, chapter 14 now separates practical ability from a negative directive, and chapter 24 presents hi, ke, ti, and ho as claimed sources rather than ranks or guarantees of truth.

Direct base vocabulary replaces older detours where the intended concept is now lexicalized: kurisha (storm), pharelo (cook), sheloa (bloom), howai (evening), horae (radiant), milaro (message), and napa (bread). Missing word-table support is added for kau, powea, shia, and mu. Optional Work root piru gives way to base miona, leaving the general primer with no module vocabulary.

The active teaching-corpus ledger records the file-by-file findings. The roadmap, coverage ledger, deferred-work record, and handoff package now resume SEM-09D at pamphlets/.

Voice and presentation

The Humanizer and Phi voice passes remove prescribed pace and daily quotas, soften claims that grammar produces care or honesty, and keep the household's warmth without making the lessons coy. The batch audit caught and rewrote repeated "is complete. You can..." closers and several participial tails that had stamped different chapters with the same model rhythm. New prose contains no em or en dashes, curly quotes, banned inflation vocabulary, or -bearing constructions.

Scope

No root, gloss, module membership, or vocabulary entry changes. The lexicon remains at 1,275 entries, including 261 optional roots and 393 module memberships. The phonetic-neighbour baseline is regenerated because its corpus-frequency column reflects the revised primer examples.
