opened a small PR (reversible observation dismiss) + a bigger idea i wanted to run by you

[20alexl]

hey — i build a small memory tool for claude code too (claude-engram, python/hooks based) and i've been reading through claude-mem pretty closely. we overlap a lot, but there's a couple things engram does that i think could slot in without fighting how it works.

i went ahead and put up a small PR for the tiniest one: #3114. reading the schema i noticed observation_feedback (schema.sql:177, "usage-signal tracking for tier routing") is declared but — near as i can tell — never actually created by a migration (looks like schema.sql is a reference doc and the real table creation lives in SessionStore). so the PR wires it up the same additive, idempotent way you create the other tables (IF NOT EXISTS + a version guard, not a data migration), and uses it for a reversible "dismiss this observation": hide a stale or wrong one from the file-context banner / search / session-start injection, but keep it in get_observations so nothing's deleted, fully undoable. default-off write, no new deps, tests green. one honest heads-up is in the PR (dismissed stuff can still come back through chroma-ranked search, since that hydrates by id, which i left unfiltered on purpose). easy to close if that table's spoken for or you'd rather not — figured a small PR is easier to react to than a wall of text.

the bigger one i did NOT build, since i didn't want to presume: a real checkpoint. your AI session summary is nice but it's model-written, only the most recent one really renders, and with no precompact hook it doesn't survive a compaction mid-task. engram has a user-written one instead — current step, what's left, files, warnings ("don't touch legacy auth.py"), next steps — saved on purpose, kept as a small per-project ring where a deliberate save beats a throwaway auto one, re-injected at session start. it'd fit as type='checkpoint' on your observations table (free-text type + fts, no migration there), rendered above the AI summary so they complement instead of collide, default-off. i'd build it if you want it — framed as complementing next_steps, not replacing it.

there's a few more if the direction's interesting — blast-radius/impact reusing the tree-sitter parser you already ship, a "you've hit this error before, here's the fix" line on failures, a search-spiral nudge — all opt-in, small separate PRs. i left out everything you already do well (typed search, file-context on read, decisions/timeline, saving typed memories) — not trying to reinvent those.

what i'm asking:

• the PR: is observation_feedback free to use like this, or is it reserved for something specific?
• the checkpoint: worth building, or does it feel redundant with next_steps?
• bigger picture — is "opt-in, deterministic, surface-the-right-thing-at-the-right-moment" a direction you even want in claude-mem, or would you rather keep recall model-driven? totally fine either way, i'd just rather ask than send you stuff you don't want.

thanks either way — the tool's genuinely good.
