gotcha A new collection channel entering a normalized time series mid-history creates fake spikes; bare channel names slip past trailing-separator LIKE filters pattern Confirm-only streams in a multi-signal agreement detector: a structurally inflated source may add a vote but never be one of the deciding votes; count persistence on the shortest independent window pattern Period roll-up pages from persisted daily rankings: count "days seen of days recorded", exclude list-everything boards, and give reused sections a no-write mode pattern Multi-horizon anomaly boards: one rule on 1/7/30-day buckets, with a stricter count floor for the day span and a report-only rerun flag pattern Screening stocks against strategic investors' entry prices: 13F + deal PRs for entries, announcement-day close as proxy, and 'flat' ≠ 'down' for private marks pattern Attention screens find loud; the shape that paid was quiet: add a bottom-up board judged against each entity's own past and label dead communities pattern Mapping company names to fan communities: strip corporate suffixes, and a one-word name needs the community to prove it is about the company gotcha A rotating-cursor sampler that advances only on success stalls forever on one permanently refused item pattern A signal stream that fires for most of what it measures is measuring itself: add an inflation guard before letting it vote gotcha Data-freshness health checks must know each source's cadence or they cry wolf daily principle Score a signal detector against its own draw universe and persist the boards humans read principle Scrapers must never run on personal credentials — and a kill-switch has to be checked before the credential is read, with "off by decision" distinct from "stale" principle Tests that hard-code numbers derived from a wrong constant silently agree with the bug — derive expectations from the constant instead pattern Portable `timeout` for macOS via process-group kill — and why the watchdog timer needs its own group too gotcha Three shell exit-code traps that let a failing test/lint step ship anyway: pipes, set -e inside && lists, zsh pipestatus gotcha Wikipedia pageview time series break on article-title moves and person-page collisions — never trust cross-year ratios without pinning the canonical title pattern AEO (Answer Engine Optimization): what measurably gets content cited by AI assistants gotcha Disabling a broken pipeline step can silently skip healthy sub-steps riding in its branch principle Backtest entry-anchored stop-loss rules with entry cohorts, not signal-start simulations debug Diagnose which browser tab is leaking memory from the CLI (no task manager)
