Updates the counts (183 -> 142, python_pkg 50 -> 0) and records what the eight python_pkg packages taught: the seam-selection rule, that a mispointed patch can hang rather than fail, and the copy-preamble-then- let-ruff-prune order for test splits. Adds docs/shell-split-recipes.md for the linux_configuration tranche, where there is no pass count to verify against - names the two live systemd units that point at repo paths and the jscpd trap on the first multi-lib commit. Decision 10 records the user's call to fix lint rather than relocate a per-file-ignore. The handoff had grown to 280 lines splitting it out, which would have been a new violation; it and both recipe docs are now under the cap.

Shell split recipes for the 250-line cap
Split out of refactor_claude_todo_resume.md (which is itself capped).
Applies to linux_configuration/ and phone_focus_mode/.
linux_configuration and phone_focus_mode have no test suite and no
coverage gate, so none of the above transfers. Decision 6 governs:
bash -n + shellcheck + systemctl cat path checks, and never execute an
enforcement script that mutates the live system or the phone.
-
After each split,
bash -nandshellcheckthe entry script and every new lib. Neither catches a lib that is never sourced. -
So also: for each new
lib/*.sh, grep the entry script for thesource/.line naming it, and confirm the path resolves from where the script actually runs (${BASH_SOURCE[0]%/*}or absolute — never a bare relative./lib/). -
Two live units point at repo paths and break if a file moves or is renamed.
systemctl catthem after touching either:/etc/systemd/system/dns-blocklist-refresh.service→scripts/single_use/features/setup_dns_blocker.sh refresh/etc/systemd/system/media-organizer.service→scripts/single_use/utils/organize_downloads.sh
Every other in-repo unit references an installed copy under
/usr/local/, so those are only at risk if the installer is what you split. -
Prefer files that nothing references first — pure lint risk.
-
Watch jscpd on the first multi-lib commit: repeated
set -euo pipefail+ source-guard headers across several new libs is exactly what pushes duplication toward the 2% threshold, and it only fires on the realgit commit.
