The Shema (Devarim 6:4-9, 11:13-21, Bamidbar 15:37-41) deliberately
oscillates between singular ("you, sg.") and plural ("you, pl.")
voice. Devarim 11:14 famously switches mid-verse from אַרְצְכֶם (2mp)
to וְאָסַפְתָּ דְגָנֶךָ (2ms). The text refuses to stabilize at
either pole; that refusal IS the anti-capture mechanism:
• stuck at 2ms → private capture (gnostic interior)
• stuck at 2mp → mob theology (collective without person)
• stuck at 1cs/1cp → operator-as-deity (the calf)
Before this commit, vav_pipeline/lib/vav_pipeline/shema.ex — the
module literally named after the Shema — encoded none of this. No
markers for person/singular/plural anywhere in the file. The chat
review surfaced this as "load-bearing anti-capture, missing".
Changes:
L1Reader.extract_voice/1 walks every word of a verse, parses the
OSHB morphology codes already present in L1 (Vqq2ms, Sp2mp, Pp1cs,
Vqi2mp, …), and returns a profile with markers, summary by
voice-key, dominant pole, and oscillates_within_verse boolean.
Strips the H/A language marker that prefixes the first /-segment of
each morph string — without that, every verse-initial verb (HVqi…)
was being silently dropped.
ShemaContext now carries voice_profile on every reception (both
receive_context/1 and receive_context_at/2). The voice is computed
fresh from L1, never cached.
8 new tests in test/shema_voice_trajectory_test.exs verify the
extractor against four anchoring verses:
Devarim 6:5 — uniformly second-singular (5 markers)
Devarim 11:13 — dominantly second-plural (5 second-plural markers)
Devarim 11:14 — oscillates_within_verse: true (the mid-verse switch)
Bereishit 1:1 — only third-singular (no addressee)
Plus three context-level tests confirming ShemaContext exposes the
field, computes it fresh, and traces a non-stabilizing trajectory
across 11:13 → 11:14 → 11:19.
Full vav_pipeline suite: 288 tests, 3 failures (all pre-existing
Shabbat-day calendar failures unrelated to this change), 19 excluded
(L3 PostgreSQL).
Still open: the across-verse stabilization-detector. ShemaContext
now KNOWS its voice; nothing yet refuses a sequence of receptions
that all stabilize at one pole. That belongs downstream — probably
the kushya generator (kal-vachomer challenge when voice has not
moved in N receptions). Logged in Pass 2 of
~/shorashim-conversation-review.md (Finding A).
