Implement genpersona:export-sft SFT data export command

Abandoned

Researched the project conventions (existing genpersona commands, MinHash service, RedditPostBody model, database schema), created ExportSft.php with the full pipeline: MySQL-only read of swingersr4r posts, per-author capping (~40), transient MinHash dedup, stratified sampling across age bucket × gender_config × seeking, by-author train/val split, privacy-hashed authors (HMAC-SHA256), and base-agnostic JSONL export to storage/app/genpersona/sft/. Validated with --limit=500 --dry-run (45,244 candidates → 500 final) and a real --limit=500 write (train.jsonl/val.jsonl/stats.json). Patched a location placeholder normalization. Started the requested --limit=15000 run, but the transcript ends during execution.

outcome

Command exists at app/Console/Commands/GenerativePersonas/ExportSft.php, validated at 500 rows; 15000-row run was initiated but not confirmed complete in this transcript.

next steps

  • Verify completion of the --limit=15000 run and check output files
  • Run pint on the new file if not already done
  • Write findings to scratchpad (tagged ["genpersona","finetune-export"])
  • Comment 'READY FOR REVIEW — ...' on todo 612
  • Stop per instructions

key decisions

  • Used stable pseudo-random ordering (ORDER BY RAND(seed)) for representative-not-top sampling
  • Transient MinHash dedup using in-memory signature generation and Jaccard comparison within the sampled pool (no DB writes to text_minhashes)
  • Author hash uses HMAC-SHA256 with the app key as secret (hash_hmac('sha256', $name, $appKey))
  • Stratified sampling: assign each post to a (age_bucket, gender_config, seeking) stratum, round-robin allocate one per stratum before filling remainder
  • By-author split: train authors and val authors are disjoint sets of author_hashes
  • Nullable location normalized: placeholder 'none' from the DB is mapped to null in JSONL

open questions

  • Did the --limit=15000 run complete successfully? (transcript truncated before output)
  • Was pint run on the new file?
