Anchor status: read-only view of anchoring debt (ticket 0010) - #321

Conversation
cog anchor status --scan <dir> reports the anchoring state of every sealed bundle without acting: anchored, anchored with a stale marker, pending (recorded debt), or unanchored with no marker at all — the silent-debt class left by emission while anchoring was unconfigured. It also sweeps for stale and orphaned pending-anchor markers. Reconcile's read-only sibling by construction: same candidate scan, same per-kind request builders, same root shape gate, same chain-verified AnchorSet fold (a tampered log refuses to report). The status path opens no Anchorer, never creates a missing log (missing log is a loud error pointing at `cog anchor init`), and never writes or deletes markers — enforced by a full-tree byte-snapshot test. Debt is information, not failure: exit is zero once the scan completes; nonzero is reserved for operational errors. Gating on debt stays --require-anchor's future job. Ticket 0010; implemented by Codex (gpt-5.5), reviewed by Claude. Validation: cog-cli anchor tests 32/32, cargo fmt --check clean, cargo clippy --workspace --all-targets -D warnings clean, cargo tree -i magpie-log = cog-anchor sole direct dependent.

cog anchor status --anchor-key … --anchor-log … --scan <dir>— the read-only sibling of reconcile. It reports, without acting, the anchoring state of every sealed bundle in the tree:anchored/anchored_stale_marker(debt already paid; the marker is reported, not deleted — cleanup stays reconcile's job)pending(unanchored with apending-anchor.jsonmarker: recorded debt)unanchored_silent(unanchored with no marker — the class left by sealing while anchoring was unconfigured, where emission writes only a notice; surfacing these is half the command's point)Read-only is the invariant, not a preference. The status path opens no
Anchorer, never creates a missing log (anchor_status_log_missingis a loud error pointing atcog anchor init— a wrong path must not masquerade as an empty estate), and contains no filesystem mutation calls. A test snapshots the log bytes and every file in the scan tree before/after and asserts byte-identity. TheAnchorSetfold replays a chain-verified log, so a tampered log refuses to report — same refusal reconcile has.Exit policy: zero once the scan completes, regardless of debt — debt is information; gating on it is
--require-anchor's future job (queued from 0007b). Nonzero is reserved for operational errors (unconfigured, missing key, missing/tampered log, unreadable scan). Unparseable/ambiguous bundles are reported and counted, exit zero, same rationale as reconcile.No new machinery: reuses reconcile's candidate scan, per-kind request builders, root shape gate,
AnchorSet::from_log,read_verifying_key,pending_anchor_marker_path, andresolve_anchor_paths. No changes tocog-anchoror any domain crate.Ticket:
