Degenerate estimators in tag-graph analytics: label-propagation hairball needs a lift-threshold sweep, and per-session HHI over rarest-tags is scattered by construction
Pinned/restored browser tabs poison session-level "gateway" and "revisit" analyses — use a [REDACTED] and annotate opener share
Share-ratio metrics: eps-padded denominators and mismatched normalizations both fabricate signal — gate support and normalize both sides from the same pool
Lift-ranked co-occurrence "surprising pairs" boards saturate with ceiling artifacts — support floors alone don't fix it
sklearn KMeans cluster_centers_ is already dense — calling .toarray() raises AttributeError
[REDACTED] authoritative fast-path disables PII/NER scrubbing — unsafe for repo-mined text
Claude Code Stop hook fires per completed turn; SIGKILL mid-generation fires NEITHER Stop nor SessionEnd — bind per-turn side effects to Stop, not SessionEnd
claude-opus-4-8 streams EMPTY thinking deltas via Claude Code — "missing thoughts" is the model, not your display pipeline
burst() entry nodes: selectDiverseSeeds' type-diversity bonus silently evicts higher-scoring seeds from the top-5
Chat turns processing queued (mid-turn) messages silently vanish from [REDACTED] — parallel code path missed by earlier persist fix
SOMNUS.md spec drift: absolute "cannot autonomously create" claim was only true of one subsystem
Boolean divergence flag manufactured false confidence when shadow-compare never armed
Cypher NOT ... STARTS WITH on a nullable property silently disables a guard clause (three-valued logic)
Neo4j migration runner: dry-run mode via paired read-only count cyphers + MERGE-collision data-loss detection
openclaw message read --json silently truncates stdout at ~64KB, breaking JSON parse on large Discord reads
Ollama embedding health checks silently broken: deprecated endpoint 500s on long input + lexical search masks a dead vector layer
A CLI named `cc` is shadowed by the C compiler on PATH — rename, don't reorder PATH
console-gateway/api OTel traces never link cross-service — no propagation.inject/extract anywhere, tsx blocks auto http/undici instrumentation
Vitest gate tests fail after copy string update — assertions hardcode old literals
Six-beat React splash renders recognition/locked as dead-black: beat machine never advances, match-invert and locked-overlay branches gated shut, no degraded path
