Carl Bonde at Paris: a memorial to Louis XIV (1676) and a despatch to Charles XI (1677), one number table

A number table (numbers 19–178 for letters, word codes from about 240) rebuilt from the Swedish chancery’s decipherment of a despatch of 1675, finished on one page of the memorial itself, frozen, and applied to nine held-out pages of the French memorial of the Swedish envoys to Louis XIV: 546 of 764 words (71.47%), read in part. Its later state reads the cipher runs of a Swedish despatch of 1677 (24 of 30 words, too short to test). The envoys press France to turn on Denmark and to send a squadron to Gothenburg. The first test of the key failed its own bar, and 43.5% of the letter values on the held-out pages come from context, not from the gloss.

TASK: take a partial decipherment further: Carl Bonde at Paris: a memorial to Louis XIV (1676) and a despatch to Charles XI (1677), one number table

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/bonde1676.html (read it first: how the text was read, the key, the reading)

OPEN GAPS (from NOTES.md, "## Remaining gaps")
  1. [open-codes: doable now] Word codes 240, 245, 267, 324, 463 (one unit each) and 314 (two units) - blocker: open-codes; senses from context only (267 alliance, 324 discours, 463 reputation?)
  2. [no-key-material: needs a new source] Seventeen numbers with no value in v3, values proposed after the decodes (99 st, 44 x, 109 ff, 120 q, 129 y ...; `holes.md` 2) - blocker: no-key-material; testing them needs fresh text in this table, and the volume's bare French cipher is used up
  3. [illegible: needs a new source] Numerals cut at the gutter: 68 units hold one - blocker: illegible; lost in the binding
  4. [no-key-material: needs a new source] Probable nulls 173-178, 3, 4, 8 - blocker: no-key-material
  5. [needs-physical-access: needs a new source] Trolle-Bonde D.1 (1910), Höjer 1875, Grauers 1926 and the French side (AAE) not seen - blocker: needs-physical-access
  6. [open-codes: doable now] Despatch of 1677: word codes 418 (twice, "en") and 435 (once); v10, made later from glosses, gives 418 = march and 435 = Preussen, not used - blocker: open-codes
  7. [open-codes: doable now] Despatch of 1677: "illa", "inställa" (spelt short by the key), "Paez" (46 a weak value), counted not read - blocker: open-codes
  8. [too-short: needs a new source] Despatch of 1677: 30 word units only - blocker: too-short

ALREADY TRIED (from NOTES.md, "## Escalation")
  [x] siblings: the neighbouring leaves of R0003797 opened; 107-109 are the cipher tail of the 1675 despatch (glossed on 105-106); the 1677 despatch of 17/27 Nov (479R-481R) decoded at 62%, not filed; 327-330 (Swedish letter with Lillieroot) not attempted here
  [x] clear-pages: the clear Swedish and French between the cipher runs read and used as context
  [x] known-keys: no other Swedish 1670s table is known to this repository; the glosses of the volume are the key source
  [x] print: LIBRIS, archive.org full text, Runeberg, Wimarson I-III, Varenius, Recueil des instructions: nothing on these two texts; Trolle-Bonde D.1, Hojer 1875, Grauers 1926 not seen
  [x] key-rebuild: key v3 from the 1675 gloss, v4-v9 from glosses and context; further values proposed after the decodes are not counted

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/bonde1676/NOTES.md in full, and the
   key, transcription and reading files it names; lang/README.md (shared language models).
   Work in targets/bonde1676/. 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/bonde1676/. 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+bonde1676&page=bonde1676.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.

Open gaps

gold can be done now: the images and the key are online, it needs only work. grey needs a new source first: a key, a better scan, an edition or the archive.

One closed gap counts: a code group valued, a passage re-read, a key or clear copy found elsewhere. It is credited to you on the write-up.
