name	ars-unmark-read
description	ARS /ars-unmark-read — rescind a user-attested reading signal for one or more citation keys
disable-model-invocation	true
user-invocable	true

Rescind a previously recorded USER_ATTESTED_READ declaration for the named citation key(s). Per v3.6.8 spec §3.6 firm rule 3, the session-scoped peer file <passport-stem>_human_read_log.yaml is append-only: rescind writes a rescinded_at: <ISO 8601> field on the matching entry rather than deleting it, so audit replay can reconstruct the user's signal trajectory. The next finalizer pass will demote any coverage-dependent <!--ref:slug ok--> back to <!--ref:slug LOW-WARN--> for each rescinded slug.

The dispatching agent substitutes <path> below with the active Material Passport path from session context before executing (the quoting is preserved so paths containing spaces remain a single argument). The CLI requires the citation_key to exist in literature_corpus[] AND to have an unrescinded prior mark in the read-log; hard-fails otherwise with the canonical [ARS-MARK-READ ERROR: ...] message.

Implementation:

python3 scripts/ars_mark_read.py $ARGUMENTS --passport-path "<path>" --unmark

Note: this command was ported from the ARS Claude Code plugin (Imbad0202/academic-research-skills, CC-BY-NC-4.0). The deterministic tooling it references (scripts/*.py, MODE_REGISTRY.md, shared/) ships in the upstream repo — clone it alongside this plugin if you need script-based features such as the citation verification gate.
