# NOTICE — external sources absorbed into `skills/`

The kit is self-sufficient (STANDARDS §7, owner decision M-2). The sources below were
**harvested, not vendored**: their best rules and gotchas were paraphrased in our voice and
fitted to our stack in [`docs/attribution/EXTERNAL_LEDGER.md`](docs/attribution/EXTERNAL_LEDGER.md) (content rows) and
[`docs/attribution/STYLE_NOTES.md`](docs/attribution/STYLE_NOTES.md) (skill-writing techniques only). Never more than 2 consecutive
lines verbatim from any source; no external code landed, only the rules the code illustrates.

Licenses below are what was observed in the local clones on 2026-09-24. Note: STANDARDS §7
states all listed sources are Apache-2.0; obra/superpowers and DietrichGebert/ponytail are in
fact MIT (techniques only, no content taken). Flagged for the moderator; no action taken.
