Tested against Stellar Protocol 23 (Whisk).

• ratesengine-ops resume-stalled subcommand. Resumes every stalled backfill cursor with a remaining range in a single invocation, replacing the hand-rolled SQL+shell loop operators had been using to chase down the F-0020 cascade-residue gap. The subcommand reads ingestion_cursors, filters to source LIKE 'backfill%' rows whose last_updated is older than --min-lag (default 1 h) AND whose last_ledger is strictly less than the parsed to from sub_source (<from>-<to>:<decoders>), then for each plan invokes the same runBackfillChunk path the regular backfill subcommand uses, with -resume semantics. Flags: --min-lag, --max-resumes (safety cap), --source-filter (substring match against decoder CSV — e.g. defindex to target one source), --bucket, --parallel, --refresh-caggs, --dry-run. Per-cursor failures are logged and the loop continues; exit non-zero only when at least one cursor errored. Live dry-run on r1 found 167 candidate cursors, 50 actionable (cursors with remaining work) and 117 skipped (stale-by-time only — at-target, never vacuumed); the 50 actionable plans are the dominant population of the 1-2% per-source density gap. Two test files pin the parser (parseStalledCursor — 10 cases covering well-formed multi/single-decoder, at-target skip, inconsistent-cursor skip, garbage sub_source, overflow, CSV sort) and the filter chain (planResumeStalled semantics — source-prefix → min-lag → source-filter → max-resumes precedence). Sequencing: cursors run serially in this first cut; concurrent operator invocations against disjoint --source-filter values are the parallel-across-cursors path. Aligns with the post-F-0020 operational posture documented in docs/operations/backfill-with-live-ingest.md.
