Dsh Recall

Key features

• Three-layer hybrid retrievalLiteral / fuzzy / semantic merged automatically with a coverage gate (≥90%) and a silent degradation chain
• FuzzySelf-built trigram + char-bigram index (zero dependencies): Rough wording, remembered fragments, typos / missing chars
• Recall happens in two stages, and the second stage only fires when the agent actually needs it
• Compaction is where memories get lost — the harness summarizes, the original text is shadowed.
• Progressive disclosureLight coarse recall by default (titles + snippets + events, 100–800 tokens)
