# Pre-commit advisory: warn when newly-added essay files are missing a
|
|
# monogram (mark.svg) or the epistemic status field. Warning only —
|
|
# this hook never blocks a commit. The author is the one staging, and
|
|
# the audit table at `make audit-marks` is the canonical view; this
|
|
# hook just nudges at the moment of commit.

# ln -s ../../tools/hooks/pre-commit-marks.sh .git/hooks/pre-commit

|
|
#
|
|
# bash tools/hooks/pre-commit-marks.sh
|

# Scope: newly-added (status `A`) .md files under content/essays/.
|

# Modified files are not warned about — the author has presumably made
|
|
# a deliberate choice about marks by then.
