 Judge each candidate from its name, description, topics, and language against CONTRIBUTING Quality Requirement 1 (Serves Python Developers), and name the current use case it would compete in. The screen is loose: drop only what plainly fails, and pass anything uncertain on, since `audit-the-list` is the real judge. In a full scan, read the `prior` column as context and overturn a rejection only on new evidence.
 
-Append each screen-out to `local/starred-scan.tsv` as it is decided, one `repo<TAB>yyyy-mm-dd<TAB>reason` row (create the file with header `repo	date	reason`), so an interrupted run keeps its work. Only append rows: the script reads the last row per repo, and it prunes rows for repos the maintainer no longer stars. A survivor no current use case fits is a structure question: carry it to review with its evidence. Done when every candidate is a ledger row, holds a target use case, or is a structure question.

-- **Added**: follow `audit-the-list` step 5 for the README change, one commit per entry. When the entry links a different repo than the star (a Python binding or client of a starred engine), also append a ledger row `already listed as <entry> (<owner/repo>)` for the star, since the script only recognizes a star whose own repo is linked.

When the entry links a different repo than the star (a Python binding or client of a starred engine), also append a ledger row for the star's URL with reason `already listed as <entry> (<owner/repo>)`, since the script only recognizes a star whose own repo is linked.
 - **Rejected**: a candidate with verdict `reject` gets one line under "Rejected Additions": `- owner/repo -- yyyy-mm-dd, <downloads>/month (<source>): <reason>.`, replacing its earlier line. This exact rejection takes precedence over a parked ledger row.
-- **Parked**: leave listed entries in README.md. An unlisted repo with no prior decision needs no record. To reopen one screened out or rejected before, remove its exact "Rejected Additions" line and append `owner/repo<TAB>yyyy-mm-dd<TAB>parked` to the ledger. Its earlier screen-out rows stay as history. The marker also exempts this repo from an `owner/*` rejection; leave that organization line in place for its other repos. A later screen-out or exact rejection excludes the repo again. A new organization-wide rejection must explicitly resolve any parked exceptions it is intended to cover.
