“Quem novit” to Christian IV, 20 July [1627 or 1628]

TASK: take a partial decipherment further: “Quem novit” to Christian IV, 20 July [1627 or 1628]
This page: https://dbourdeau.github.io/cyphersolver/further/quemnovit1627.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/quemnovit1627.html (read it first: how the text was read, the key, the reading)
  Date:       1627–28
  Outcome:    ciphertext-only break · partial
  Read now:   68.0% of the deciphered cipher tokens give sense (pieces below may be untouched)
  Files:      https://github.com/dbourdeau/cyphersolver/tree/main/targets/quemnovit1627 (NOTES.md, key, transcription, reading, scripts)

OPEN GAPS (from NOTES.md, "## Remaining gaps")
  1. [no-key-material: needs a new source] codes 117 (twice) and 118 - blocker: no-key-material; three tokens, no other leaf in this code is known, the sense narrows 118 to the place of writing (Venice likely, not proved)
  2. [illegible: needs a new source] g/q sign class (13 units), pi/Z/n and c/e classes (7 units) - blocker: illegible; the tails of g and q cannot be told apart at the resolution available here (image 443, 4473 x 3436), three readers split; a person comparing them at full size is needed

ALREADY TRIED (from NOTES.md, "## Escalation")
  [x] siblings: neighbouring leaves images 426-475 of unit 261377 swept; image 447 is a chancery sheet for Schultetus's number code, a different cipher; no sibling in this key
  [x] clear-pages: no decipherment on or beside the leaf (images 442-449 seen)
  [x] known-keys: zobel1629 (figures) and Schultetus's number code are different systems and do not apply; no other key of this series is a letter-sign substitution
  [x] print: Danske Magazin, Christian IV's egenhaendige Breve, Danske Samlinger, Historisk Tidsskrift, Swedish Handlingar, DECODE, Cryptiana: nothing (thin: an anonymous letter cannot be searched by name)
  [x] key-rebuild: key built by hand from a crib and word patterns; no value for the one n-form sign, none possible for the code numbers
  [x] retry: the three independent readings and their majority adjudication were each decoded with the key; the remaining 33 units are disputed signs, emendations or codes

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/quemnovit1627/NOTES.md in full, and the
   key, transcription and reading files it names; lang/README.md (shared language models).
   Work in targets/quemnovit1627/. 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/quemnovit1627/. 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+quemnovit1627&page=quemnovit1627.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.
