the expensive failure in AI-assisted coding isn't a bad line of code — linters and tests catch those. it's an agent confidently re-implementing something your team already tried and killed. that's been the selvedge pitch from the start: an append-only store where the agent logs its own reasoning at change time, so "we tried that and it broke revocation" survives the session that learned it.
v0.3.10 solved delivery — the memory now arrives at session start instead of waiting to be asked ("Delivery, Not Storage" [arXiv:2607.20972] measured why that matters: zero voluntary memory operations across 114 turns against a pre-seeded store, while deterministic injection landed every time).
v0.3.11 is about the two halves of the sentence "rejected paths, retained." first: making the rejection itself first-class. second: making retained something you can check instead of something you take my word for.
rejections are now stated outcomes, not inferences
until now, selvedge could tell you a path was abandoned mostly by reading tea leaves: a remove event near an add, a proximity window, a heuristic confidence score. useful, but it's inference — and inference is exactly what this tool exists to replace with testimony.
