docs: byte-identical collapse edge + dated-prompt workaround - #11
Merged
Conversation
…rompts Collapse is exact byte-identical matching (deliberately — fuzzy matching would risk merging distinct facts and hiding evidence). A recurring automation prompt that interpolates a date/run-number produces near-identical turns that slip through. Document the capture-time fix (prune --turns-containing on the stable prefix; ignore-markers.txt when the prompt heads its own sessions) and that there is no ongoing per-turn skip yet.

Documents the collapse limitation a reviewer flagged:
recallcollapses only byte-identical hits, so a cron/automation prompt that interpolates a date or run number produces near-identical turns that aren't collapsed.We keep collapse exact on purpose — fuzzy/normalised matching would risk merging genuinely distinct facts (
port 8443vsport 9000) into one and hiding real evidence. So this documents the capture-time fix instead:prune --turns-containingon the stable prefix (which matches every dated variant), andignore-markers.txtfor prompts that head their own sessions. Also notes the current gap — no ongoing per-turn skip for a recurring prompt embedded mid-session — and adds a quick-reference row.Docs-only.
