the second scroll: the mesorah snapshot, pinned and read (bishe'arecha step 6)

Devarim 17:18 — the king writes his copy from before the priests, not from
memory. scripts/build_mesorah.py takes one open-licence version per work
per language from the Sefaria export (bucket sefaria-export, catalogue of
2026-10-02; Public Domain / CC0 / CC-BY / CC-BY-SA only, checked in every
file; no CC-BY-NC — the Bavli is Wikisource's) and lays it down beside
L1: mesorah/works/<slug>/{he,en}.json, index.json, integrity.sha256,
build_report.json. 128 works (Rashi, Onkelos, Ramban, Ibn Ezra, Sforno
on the Torah; all of Mishnah; 37 Bavli tractates; Bereshit and Shemot
Rabbah, Sifrei, Tanchuma), 256 files, 44.9 MiB, tree hash 7d5b3a6c…
computed as L1's (sorted relative path, then bytes; the two post-hash
files excluded). What is out, and why (licence), is in Terumah §E5.

Read, never fetched: korban_processor/mesorah.py finds citations as
written (Rashi on Devarim 6:5, Berakhot 2a, Mishnah Berakhot 1:1,
Bereshit Rabbah 1:1, Sifrei Devarim 32, Tanchuma Bereshit 1 …), resolves
each against the snapshot (complex works through their unnamed node,
Tanchuma by parashah), lists them as examination.mesorah_references, and
makes every passage found a given source for that examination — so a
claim about Rashi anchors in Rashi or does not. The Vav Pipeline couples
coupled(reference(R), mesorah(Work, [Address])) or not_in_mesorah; the
engine accepts mesorah/2 as a terminal and not_in_mesorah is Form 4.
VavPipeline.Mesorah pins the hash, re-reads the tree at startup and every
ten minutes, and /kodesh/health carries mesorah_hash. Mounted read-only at
/mnt/mesorah in the vav-pipeline and korban-processor images. L3
bedikot.mesorah (migration 20261013000002).

Also: the 1-in-12 Day6 serving failure of 2026-10-04 reproduced with seed
446116 — HaltMonitorTest left the system halted; it now resolves on exit
and the Day6 setup is defensive. Construction §3.11, Terumah §E5, Tamid
§1.1, bishearecha §IV, KOHEN, AGENTS. Doorpost 0638d4eb…. Elixir 604/0
(seeds 835592 and 446116), korban 294/1 skipped, Prolog bedikah 44/44,
L3 10/0.

Half of a <i>log</i> [is to be poured from] for three or four. And from [a vessel containing] one <i>log</i> [of water], five or ten or even one hundred [people may wash their hands]. Rabbi Yose says: but only provided there not be less than a quarter [of a <i>log</i> remaining] for the last one of them [to wash]. One may add [water, by pouring it onto the hands past where it had fallen] on the second [pouring of water; i.e. on a third pouring, one can pour past where the waters fell on the second pouring]. But one may not add on the first [pouring; i.e. on the second pouring, one may not pour past where the waters fell on the first pouring]. ","One may pour [water for washing] onto the hands from all [kinds of] vessels, even from vessels of bovine dung, from vessels of stone, or from earthen vessels. One may not pour [water for washing] onto the hands out of the sides of vessels [i.e. from vessel fragments], nor using the [broken off] bottom of a large jug, nor using the bung of a cask, nor may one pour [water] onto [the hands of] his fellow out of the hollow of his [own] hand, since one may only fill, sanctify, or sprinkle the <i>chatat</i> waters [the waters containing the ashes of the red heifer, used as part of the purification ritual] with a vessel, nor may one take them into one's hands. And nothing can be preserved [from being rendered impure, in cases of an impurity caused by being overshadowed by an enclosed area containing an Origin of impurity] by means of a tight seal [which can sometimes protect against an overshadowing impurity], unless it is [contained within] a [whole] vessel. And something can only be preserved from [being rendered impure by an impure object contained beside it within] an earthenware vessel if it is itself a vessel.","Regarding waters which have become unfit for animals to drink, if they are in [any kind of] vessels, they are invalid [for washing one's hands]; and if they are in the ground [i.e. in a ditch], they are valid [for washing with them, by immersing one's hands in them]. If ink, sap, or metallic dye fall into them and change their appearance, they are invalid [i.e. the waters are invalid for washing]. If they had been used for any occupation, or if one soaked one's bread in them, they are invalid. Shimon, the Teimani said: even if one intended to soak [one's bread] in these [waters], and it fell into those [waters instead], they are valid [for washing].","If one rinsed vessels in them, or if one cleaned out measuring vessels with them, they [i.e. the waters used] are invalid. If one rinsed out [already] rinsed or new vessels, they are valid [i.e. the waters are valid to be used for washing]. Rabbi Yose invalidates [the waters] regarding new ones.","Waters into which the baker has dipped [unbaked] rolls are invalid. And when he [instead] rinses his hands in them [and then splashes the rolls with water from his hands], they are valid [i.e. the waters in which he rinsed his hands]. Anyone is valid to pour onto the hands [of another person, in order to wash them], even a deaf-mute, <i>shoteh</i>, or a minor. A man may place a cask between his knees to pour [the water over his hands, to wash them], or tip a barrel onto its side and pour [onto his hands]. An ape may pour [water for washing] onto one's hands. Rabbi Yose considers these two [i.e. tipping a barrel or using an ape] to be invalid."],["If one poured [water] onto one of his hands in one washing [i.e. pouring only once], his hand is pure. If [one poured] onto both of his hands in one washing, Rabbi Meir considers them impure until one pours [onto one's hands, in one pouring,] a quarter [of a <i>log</i>, a specific unit of volume, of water]. If a loaf of <i>terumah</i> [a portion of a crop given to a priest, which can only be consumed by priests or their household] falls into them [i.e. into the quarter <i>log</i> of waters which one washed one's hands with] it is pure. Rabbi Yose considers it impure.","Regarding one who poured out the first [waters poured for washing] onto one place [i.e. the waters fell onto a certain area on the ground], and the second [waters poured for washing] onto another place, if a loaf of <i>terumah</i> falls into the first [waters], it is impure; and if [it falls] into the second [waters], it is pure. Regarding one who poured out the first and the second [waters] onto one place, if a loaf of <i>terumah</i> falls [into those waters], it is impure. If one poured out the first [waters], and finds [afterwards] a splinter or a pebble on his hands, his hands are impure [if he poured the second waters before removing them], since the latter [i.e. the second] waters oLine truncated
