Banned languages appear in dev-environment definitions (guix.scm ×14, empty-linter mise.toml)

[hyperpolymath]

Flag from the R-16 reconciliation (2026-08-31). No edits made — owner decision requested.

Two instances of the same class: dev-environment definitions pulling estate-banned languages.

1. guix.scm ×14. Origin's 2026-08-23 guix quality pass ("fix stub/invalid names") replaced the erroneous squisher-corpus placeholder guix.scm files, but the replacement dev-shell definitions pull (gnu packages python), golang, java, and node — all banned estate-wide. Repos: bunsenite, dictask, double-track-browser, heterogenous-mobile-computing, iseriser, methodologies, nafa-app, natsci-studio, plasma-parser-writer, robot-vacuum-cleaner, sanctify-php, seamstress, session-sentinel, universal-language-server-plugin. These files were taken origin-side during the R-16 reconciliation per ruling R-28b Class 2 (the fix was 10 days newer than the local deletion); the banned-language content was flagged, not touched.

2. empty-linter mise.toml. Origin's toolchain file correctly enacts the Deno→Bun ruling (deno dropped, bun = "1.3.14" pinned — owner re-confirmed 2026-08-31), but the same file also pins python, go, java, and node.

Question for the owner: should dev-environment definitions (guix.scm dev-shells, mise toolchain files) be exempt from the language ban as build-time scaffolding, or should these pins be swept? If swept, that is a follow-up campaign, not a per-repo drive-by.

Evidence: forensics/r16-r28b-class-rulings-2026-08-28.md (Class 2) and forensics/r16-class-conflict-reports/ in the estate control tree.

Verified 2026-08-31. 13 of the 14 named guix repos confirmed (local + remote spot-checks) — iseriser is already clean, cured by its 08-23 guix quality pass. The empty-linter mise.toml claim is exact (local=remote: node/python/go/java = "latest" alongside bun, plus pip/black/isort/ruff/pytest).

But the class is larger than filed: 42 guix.scm files across 33 canonical repos declare banned-toolchain modules, and estate-wide mise.toml pins python in 543/573 files (249 repos) and still pins deno in 59 files despite the Deno→Bun ruling (remote-confirmed on e.g. metadatastician/selur). flake.nix adds ~7 more repos. Full inventory filed as a companion issue.

The owner decision this issue asks for is unchanged, and now covers ~260+ repos — worth ruling before any sweep:

• (a) Exempt dev-env definitions from the language ban — one line in the policy doc, zero sweep, this closes.
• (b) Full sweep — ~600+ files across ~260+ repos, campaign-scale, needs its own runbook.
• (c) Middle path — sweep only the 59 deno pins now (Deno→Bun is an explicit standing ruling, not a judgment call; ~59 one-line edits) and exempt python/go/java/node pins pending (a)-vs-(b).

Recommendation: (c) is executable today without prejudging (a)-vs-(b). Labelling status:needs-owner.
