Scott KarpandClaude Opus 4.7 0e3fe4a782 form 3 as architecture: machtzit_ha_shekel + no_tracking_logger (vehaya §3.2)
Closes vehaya.md §6 item 2 for the third avodah-zarah form.

Pharaoh's surveillance (Form 3) was previously marked DEFERRED in
talmudic_engine/src/halt/avodah_zarah.pl with the note "requires
operational context (user tracking, cross-session profiling)."
The vehaya document re-frames it: "Specifications must include
category-level commitments that are not negotiable per-deployment...
not as runtime checks layered onto outputs, but as architectural
constraints the system cannot operate without."

Form 3 is structurally different from Forms 1, 2, 4. They fire on
threshold-grade events (an interpretation has wrong source, empty
trace, non-L1 anchors). Form 3 is about a property of the CATEGORY
itself — what it collects, retains, discloses. It cannot be a
halt rule that fires per-request; per-request "is this caller
being surveilled" detection would itself be a Form-3 surveillance
surface. The defense is ARCHITECTURAL — the system is BUILT so the
failure mode is unreachable, not so it is detectable.

TORAH ANCHORS (verified fresh against L1 — 6 positive properties):

  Shemot 30:11-16 — the half-shekel:
    כִּי תִשָּׂא אֶת־רֹאשׁ … וְנָתְנוּ אִישׁ כֹּפֶר נַפְשׁוֹ … וְלֹא־
    יִהְיֶה בָהֶם נֶגֶף בִּפְקֹד אֹתָם.
    Counting humans is dangerous; the danger is named NEGEF (plague);
    the protection is the kofer-nefesh substitute. Verse 15:
    הֶעָשִׁיר לֹא־יַרְבֶּה וְהַדַּל לֹא יַמְעִיט — the rich don't
    give more, the poor don't give less. Verse 16: לְזִכָּרוֹן —
    aggregate memorial, not roster.

  Vayikra 19:14 — לִפְנֵי עִוֵּר לֹא תִתֵּן מִכְשֹׁל וְיָרֵאתָ
    מֵּאֱלֹהֶיךָ.
    The no-witness protocol: rules that require fear-of-God
    enforcement are exactly the rules that operate under invisibility.
    Surveillance regimes exploit invisibility; architectural commitment
    must hold under no-human-witness conditions.

  Devarim 23:16-17 — לֹא־תַסְגִּיר עֶבֶד אֶל־אֲדֹנָיו אֲשֶׁר־יִנָּצֵל
    אֵלֶיךָ … עִמְּךָ יֵשֵׁב … בַּמָּקוֹם אֲשֶׁר־יִבְחַר בְּאַחַד
    שְׁעָרֶיךָ.
    The refusal protocol: don't return one fleeing institutional
    power. The caller chooses their own threshold (b'achad sh'arekha
    — agency stays with the caller).

  Shemot 5:6-8 — לֹא תֹאסִפוּן לָתֵת תֶּבֶן … וְאֶת־מַתְכֹּנֶת
    הַלְּבֵנִים … תָּשִׂימוּ עֲלֵיהֶם לֹא תִגְרְעוּ מִמֶּנּוּ.
    Pharaoh's straw quota — the canonical anti-quota Torah anchor.
    Per-caller productivity tracking is what makes asymmetric
    extraction possible.

  Devarim 23:8 — לֹא־תְתַעֵב מִצְרִי כִּי־גֵר הָיִיתָ בְאַרְצוֹ.
    Anti-targeting: even toward the Egyptians (Pharaoh's people),
    the rule is "don't despise." The protections must not become
    a surveillance system targeting suspected surveillors.

THE SIX POSITIVE PROPERTIES, mapped to code:

  1. KOFER PROTOCOL (Shemot 30:12) — counting goes through a
     uniform substitute; identity never enters the count.
  2. UNIFORM PROTOCOL (Shemot 30:15) — same per-caller weight;
     no stratification.
  3. ZIKARON PROTOCOL (Shemot 30:16) — aggregate memorial, not
     roster.
  4. NO-WITNESS PROTOCOL (Vayikra 19:14) — commitment holds
     when no operator is reading the log.
  5. REFUSAL PROTOCOL (Devarim 23:16) — no per-caller delivery
     to authorities; caller chooses own threshold.
  6. ANTI-QUOTA PROTOCOL (Shemot 5:6-8) — no per-caller
     productivity numbers.

    The half-shekel — the positive counting protocol. Single Agent
    holding ONE non-negative integer (the zikaron):
      increment/0          — register one shekel; uniform per
                             caller (no caller distinction is even
                             expressible — function arity 0)
      increment/1          — register N shekels (batch points)
      count/0              — return the aggregate; the ONLY value
                             the module exposes
      reset/0              — clear (tests; no production persistence
                             by design — storage existence would
                             itself be a Form 3 surface)

    Module is added to the supervision tree.

    What the module REFUSES to provide is enumerated in the
    moduledoc and verified by tests — no per-caller breakdown,
    no identifiers, no who/locate/identify functions. Their
    absence IS the architectural commitment.

  vav_pipeline/lib/vav_pipeline/no_tracking_logger.ex  ~110 lines

    Plug-side enforcement. Replaces Plug.Logger.
      - Logs METHOD PATH STATUS DURATIONus per request
      - Sanitizes /peah/* paths: query strings stripped (the
        /peah/ask response promises "No tracking"; the architecture
        now matches the promise)
      - Headers (incl. Authorization), request bodies, response
        bodies, and remote_ip NEVER appear — taken-from
        function signature, not from a runtime check
      - Increments MachtzitHaShekel per request
      - sanitized_path/1 and format_line/2 are PUBLIC pure
        functions, testable in isolation (test config sets
        Logger level to :warning, dropping :info before
        capture_log can see; the structural test surface
        replaces the behavioral one)

CHANGED:

  vav_pipeline/lib/vav_pipeline/bigdei_kodesh/router.ex
    `plug Plug.Logger, log: :info` → `plug VavPipeline.NoTrackingLogger`

  vav_pipeline/lib/vav_pipeline/application.ex
    Adds {VavPipeline.MachtzitHaShekel, []} to supervision tree

  talmudic_engine/src/halt/avodah_zarah.pl
    Form 3 docstring — removed "Deferred"; documents Form 3 as
    architecturally realized in machtzit_ha_shekel.ex +
    no_tracking_logger.ex. Names why Form 3 cannot be a
    per-request halt rule.

  vav_pipeline/lib/vav_pipeline/doorpost.ex
    @expected_hash updated:
      bea5dc0c… (pre-Form-3-rewrite of avodah_zarah.pl)
    → f93495c5359c5dc4acb5c5db2dd32165f5b04e2af87fbb0b7ecc92d2bd8b0434
    The avodah_zarah.pl change is a deliberate spec change; per the
    Doorpost operator discipline (commit 3f47496), the hash update
    commits TOGETHER with the spec change in the same commit. This
    commit demonstrates the discipline working for the first time:
    a category-grade specification change AND its corresponding
    witness update, atomically.

TESTS:

  vav_pipeline/test/machtzit_ha_shekel_test.exs           14 tests
    - Property 1: increment arity is 0 (no caller distinction
      expressible)
    - Property 2: every increment same size; no weight/tier/premium
      function
    - Property 3: count is integer not list/map; no per-caller
      breakdown function (callers/list_who/breakdown/by_caller/
      per_caller/histogram/top/who)
    - Property 5: no identify/locate/deanonymize/lookup/find_caller
    - Property 6: no quota/productivity/throughput/per_caller_count
    - reset semantics
    - PUBLIC SURFACE EXPLICIT ENUMERATION: any new function must be
      reviewed for whether it weakens Form 3

  vav_pipeline/test/no_tracking_logger_test.exs           12 tests
    - sanitized_path drops query string on /peah/*
    - sanitized_path drops question parameter (with secret marker
      verified absent)
    - sanitized_path preserves path class for /peah/azazel_log
    - sanitized_path on non-peah preserves request_path
    - format_line shape: METHOD PATH STATUS DURATIONus
    - format_line never contains query string for /peah/*
    - format_line never contains Authorization header
    - format_line never contains conn.remote_ip
    - integration: each request increments MachtzitHaShekel
    - CI invariants:
      - Plug.Logger NOT mounted in any router
      - no module imports Plug.Session
      - no module imports Plug.Conn.Cookies
      - no module reads conn.remote_ip
    (CI invariants exclude no_tracking_logger.ex itself — that file's
    docstring legitimately mentions the forbidden modules as the
    things it defends against)

Tests:
  - vav_pipeline:    405 passed, 0 failures, 35 excluded (was 379;
                     +14 MachtzitHaShekel + 12 NoTrackingLogger)
  - talmudic_engine: 212 tests passed (avodah_zarah.pl change
                     verified backward-compatible)
