+// backup_dump.go — per-resource_type dump strategies for the customer-backup
+// runner. Mirrors the pgDumpRunner seam already in customer_backup_runner.go
+// so the runner can back up postgres/vector (pg_dump), mongodb (mongodump),
+// and redis (redis-cli --rdb) through ONE pipeline (gzip → sha256 → S3) with
+// ONE retention/cadence/keep-last-N policy.
+//
+// R2 (2026-06-10) — closing the durability gap. Before this file the backup
+// ladder backed up postgres/vector ONLY; the product sells "backups +
+// 1-click restore" for ALL paid resources, so Mongo + Redis had ZERO
+// automated backup (worker #103 note + GAP-AUDIT-2026-06-10). This file adds
+// the Mongo + Redis dump strategies; the runner dispatches on resource_type.
+//
+// THE GZIP CONTRACT (why this matters): the existing pg path writes a RAW
+// (uncompressed) `pg_dump --format=custom` archive into the runner's gzip
+// writer — the pipeline owns compression, the S3 object is `<archive>.gz`,
+// and the restore path gunzips then pipes to pg_restore. To keep ONE
+// pipeline + ONE object layout + ONE sha256/restore story, every dumpRunner
+// here writes RAW (uncompressed) bytes too. Concretely:
+//
+//   - mongodump: `--archive` (NOT `--archive --gzip`). mongodump's own
+//     --gzip would double-compress under the pipeline's gzip layer, bloating
+//     the object and breaking the "gunzip → mongorestore --archive" restore
+//     symmetry. Restore gunzips, then pipes to `mongorestore --archive`.
+//   - redis-cli: `--rdb -` streams the live RDB snapshot to stdout (a single
+//     uncompressed RDB blob). The pipeline gzips it to `<id>.dump.gz` exactly
+//     like the pg/mongo archives.
+//
+// SECRET HYGIENE (mirrors SEC-WORKER FINDING-2 on the pg path): the customer
+// credential must NOT sit in argv (/proc/<pid>/cmdline, `ps aux`, kubectl
+// describe crash archive) for the multi-minute backup window. pg_dump uses
+// PGPASSWORD env (splitPGPassword). mongodump accepts the full mongodb URI in
+// `--uri` — the URI carries the password, so we pass it on stdin-equivalent…
+// mongodump has no env-password knob, BUT it DOES read the URI from
+// `--uri=<file>`? No: mongodump's only password-out-of-argv path is
+// interactive prompt, which we can't drive. We therefore pass the URI via the
+// MONGODB_URI-equivalent the tool honors: mongodump reads `--uri` from argv.
+// To keep the secret out of argv we instead write the URI to a 0600 temp file
+// and pass `--config=<file>` (mongodump supports a YAML config with a
+// `uri:`/`password:` field). See realMongoDumpRunner for the exact mechanism.
