Vaudreuil to the minister of the Marine, Montréal, 13 August 1760

TASK: take a partial decipherment further: Vaudreuil to the minister of the Marine, Montréal, 13 August 1760
This page: https://dbourdeau.github.io/cyphersolver/further/vaudreuil1760.html

You are helping a public research project finish reading historical cipher letters. This one is read in part:
the key works, but some pieces are still open. Your job is to close one or more of the open gaps below.

THE READING
  Write-up:   https://dbourdeau.github.io/cyphersolver/vaudreuil1760.html (read it first: how the text was read, the key, the reading)
  Date:       1760
  Outcome:    external key matched · partial
  Read now:   96.0% of the deciphered cipher tokens give sense (pieces below may be untouched)
  Files:      https://github.com/dbourdeau/cyphersolver/tree/main/targets/vaudreuil1760 (NOTES.md, key, transcription, reading, scripts)

OPEN GAPS (from NOTES.md, "## Remaining gaps")
  1. [illegible: needs a new source] groups cut by the binding at the right edge of ff.147v-151v (20 partly visible and not restored, 27 wholly lost) - blocker: illegible; microfilm image, a clear copy would restore them
  2. [open-codes: doable now] f.147v.4 "et i" after "tiennent ce poste" and f.147v.9 "mais son se le pour-ra-t" (8 groups: 2 at f.147v.4 and 6 at f.147v.9, as in gaps.json) - blocker: open-codes; cells confirmed on the alphabetical sheet, the words are not identified
  3. [open-codes: doable now] f.147v.24-25 "au pre[..] / i si un instant favorable" (3 groups) - blocker: open-codes; the order given for the Machault, words not identified
  4. [open-codes: doable now] f.148r.13-14 "fin-i-ra bateau campagne" (5 groups) - blocker: open-codes; the officer Villemont, "fin i ra" and "bateau" confirmed, the phrase is not
  5. [open-codes: doable now] f.148v.17 "de b l[..]" (2 groups) after "quinze diverses charges du" - blocker: open-codes; the word is not identified
  6. [open-codes: doable now] f.149v.17-18 "ceux un | ton" (2 groups) - blocker: open-codes; cells 494 and 152 (ton) confirmed on the alphabetical sheet, the sense is not
  7. [open-codes: doable now] f.150v.24 "de moyen" (2 groups) and f.151v.6 "nt s" (2 groups) and f.151v.19-20 "je vous ent[..] e" (2 groups) - blocker: open-codes; cell 473 = moyen confirmed, the words are not identified

ALREADY TRIED (from NOTES.md, "## Escalation")
  [x] siblings: neighbouring records of C11A 105 (ff.136-146, 153-155: clear letters of 7 and 13 Aug 1760) opened, they confirm the names and facts; the four cipher letters of the same hand and office (cat. 1388, 1389, 1390 of April 1759 and 1392 of Nov 1759, C11A 104) fetched and tested with the same table: 1390 (354 groups) decodes as French in full with it, 1389 and 1388 use the same groups (1389 sample f.68v-69v reads: "j'ai l'honneur de vous envoyer ci-joint copie de la lettre que M. le marquis de Montcalm m'écrivit ... février dernier"); 1392 (Trémais, 6 Nov 1759) does not: its numbers are a different, smaller code mixed with clear French
  [x] clear-pages: ff.142-146 (lake Champlain, movements of the enemy, 7 Aug) and the cover letters ff.153-154 (13 Aug) checked; none is a decipherment
  [x] known-keys: both numerical sheets 272 and 274 of C11E 10 tried; 274 fits and reads the letter (the third numerical sheet, e001295276, not tried)
  [x] print: web searches (FR/EN, 5 Nov) for the letter, the cipher and the correspondents, and NY Colonial Documents vol. 10 (vetting): nothing; Tomokiyo's and Lasry's pages were searched, not opened; Casgrain's Lévis collection not read for this date
  [x] key-rebuild: 33 table cells corrected from the letter and the images (key/overrides.json); the alphabetical sheet e001295269 (rotated 90 degrees, readable at 5x) used to confirm cells 473 moyen, 152 ton, 671 bateau and to correct cell 2 (campagne)
  [x] retry: the unread groups were re-run with the corrected key and the alphabetical sheet; 9 places remain (listed above)

STEPS
0. Set up. If you can run a shell, fork and clone the repository and work inside it:
     git clone https://github.com/dbourdeau/cyphersolver.git
   Then read, in this order: CONTRIBUTING.md (how a contribution is sent and credited); README.md, sections
   "Repository layout" and "Conventions" (how readings are measured and named); targets/vaudreuil1760/NOTES.md in full, and the
   key, transcription and reading files it names; lang/README.md (shared language models).
   Work in targets/vaudreuil1760/. Add your findings to NOTES.md under a dated heading without rewriting what is there, and
   update the "## Remaining gaps" line of every gap you close. Keep WORKLOG.md there: one dated line per step
   (hypothesis, value tried, solver run, crib, control), failures included. Do not edit docs/ (the site is generated).
   If you cannot run a shell, fetch the files from the links above and keep your work in files you send with the issue.
1. Pick a gap. Start with the ones marked "doable now" (open-codes, not-attempted, left-open): the images and the key
   are online, so they need only work. A gap marked "needs a new source" (no-key-material, too-short, illegible,
   needs-physical-access) can be closed only by something new: a key
   or a deciphered sibling found elsewhere, a better image, a printed edition or calendar, a photograph from the archive.
   For those, search for that material first, and say where you looked even when you find nothing.
2. Start from the existing key and transcription in the folder. Do not rebuild the key from scratch, and do not
   re-read parts that are already read unless you find an error in them.
3. For a code group or sign value: list every place the group occurs, show how each reads with the value you propose,
   and say what still does not fit. For a passage: re-read it at the image and give the folio and line. For a missing
   letter or leaf: say where it is held and how it can be reached.
4. Measure again. Apply the key to the whole text, write the reading file, and count the share of cipher tokens that
   give sense (not an estimate). The reading is "complete" only when (1) at least 95% of its cipher tokens give sense;
   (2) no gap is left untried; (3) every letter in it is covered; (4) what stays open is scattered code groups or names,
   or pieces blocked from outside. Otherwise it stays "partial": say which gaps are still open and why.
5. Be honest. Mark every uncertain word with [?], leave unread groups as their numbers or signs, and never fill a gap
   with a plausible guess. A gap retried and still open, with what was ruled out, is worth reporting.

REPORT BACK
With a clone: open a pull request with your changes to targets/vaudreuil1760/. Say in the description which gaps you worked on,
  the share read before and after, and how you want to be credited (name, initials or handle, and a link).
Without one: open an issue: https://github.com/dbourdeau/cyphersolver/issues/new?template=further-reading.yml&title=Further+reading%3A+vaudreuil1760&page=vaudreuil1760.html
  Give the write-up, the gap you worked on (its line in Remaining gaps, or the code group, folio and line), what you
  propose, the evidence (every occurrence, the images or sources), the share read before and after, your step log,
  and the tools and AI model you used.
If you cannot open issues or pull requests, write this report for your human to send. Credit goes to the person who sends it.
