Search a NexusMem-tracked repository's remembered history: git commits, code diffs (the patch of each changed file), shell commands, tracked markdown docs, and (if enabled) conversation transcripts, per-session summaries, and github.com issue/PR threads. Returns a token-budgeted, ranked context block -- not raw search results.

Ingest new git, diff, shell, docs and (if enabled) conversation and github.com issue/PR history for a NexusMem-tracked repository into its local database. Pass pruneSource or pruneStaleShell instead to delete a dead source's nodes (e.g. the pre-hook shell scrape) rather than syncing -- dry-run unless yes is also true, since this is an irreversible full wipe of that source.

Report how many nodes NexusMem currently remembers for a repository, broken down by kind and source.

List the most recently remembered items for a NexusMem-tracked repository -- git commits, code diffs, shell commands, tracked docs, and (if enabled) conversation transcripts, session summaries, and github.com issue/PR threads -- newest first. Chronological, not relevance-ranked: use search_memory instead for a specific question.

List open contradiction verdicts for a NexusMem-tracked repository -- candidates flagged by "nexusmem stale --check-contradictions" (or automatically during sync) as likely superseded by a newer, similar node. Nothing has been written yet; use resolve_stale_suggestion to act on one.

"accept" writes a supersede link from candidateId to againstId (the same effect as "nexusmem mark-stale") -- the ranker down-weights candidateId from then on but never deletes it. "dismiss" silences the suggestion without changing ranking, so it stops resurfacing on future stale/sync runs.
