docket 0.21.0

Added

• A supersession can carry --supersede-reason restate|revise|reverse, and every claim and decision derives support (clean, flagged or unsupported) with review_owed and lost_grounds. A citation follows supersessions to the head of its chain: a restatement keeps the citing record clean, a revision flags it, a reversal removes the ground. unassessed, disputed and blocked grounds flag; rejected and revoked grounds are lost. Support that is circular and never grounded is flagged with because: circular rather than lost.
• docket review ID [--note TEXT] acknowledges a record's own revised, unassessed, disputed or circular grounds against the heads it was reviewed against. A later revision of the same chain raises the flag again. A flag inherited from a flagged or blocked ground clears by reviewing or fixing that ground; docket review refuses a record that owes only those, and review the frontier first.
• docket correct ID --supersede-reason VALUE relabels a supersession. --where takes is:flagged and is:unsupported. show --json and list --json carry support, review_owed, lost_grounds and reviews.

Changed

• A prerequisite in depends_on now follows restatements and revisions to the head of its chain instead of blocking the decision; only a reversal, or a rejected or revoked head, blocks. A --since token minted before the upgrade still matches unless a decision's applicability changed under the new prerequisite rule; then it prints a full briefing.
• Every supersession recorded before this release reads as revise, so records citing a superseded record owe review after upgrading. Relabel restatements with docket correct ID --supersede-reason restate.
• A ledger with any supersede_reason, a correction of one, or a review line cannot be read by docket 0.20.x or older. Upgrade every machine and plugin cache that reads the ledger first.
