Configuration

Key	Default	Meaning
storePath	'' (= /data/gate-store.json)	Store file; pin an absolute path in production
injectEnabled	true	Master switch for the injection gate
injectInSubagents	false	Inject in child sessions too (cost scales with children)
injectLimit	3	Max memories per injection
injectMinProbability	0.6	Relevance threshold for injection (stricter than manual recall)
prefilterLimit	40	Candidates sent to Jev
supersedeCandidates	12	"Possible duplicate" candidates for the write gate
dailyBudgetCny	3.5	Daily budget (CNY)
dailyCallLimit	3000	Daily call cap

Tuning

Every magnitude is a config value — nothing is hidden in the code. Change them in the profile's cordis.patch.yml (or the bundle's own patch) and restart DSH at process level.

Key	Default	Effect
injectEnabled	true	master switch for the injection gate
injectLimit / injectMinProbability	3 / 0.6	memories per injection / relevance threshold (pinned entries bypass it)
recallMinProbability	0.5	mem_recall threshold — also overridable per call via min_probability
prefilterLimit / supersedeCandidates	40 / 12	candidates sent to Jev / duplicate candidates for the write gate
worthReviewThreshold	0.35	below this the write gate only annotates "review suggested" — it never blocks a write
dailyBudgetCny / dailyCallLimit	3.5 / 3000	daily budget (CNY) and call cap
injectTimeoutMs / toolTimeoutMs	1500 / 15000	latency budget for the injection path / for tools
egressGuard	false	outbound-only pattern guard (opt-in)
injectInSubagents	false	inject in child sessions too

Tune from evidence, not feel: the audit log records every candidate's noul probability together with the threshold in force, so mem_gate_log (or the per-day gate-decisions-*.jsonl shard) tells you exactly what a given threshold would have admitted or dropped.

Cost model — Jev input is $0.042/M and output is free. The plugin accounts and reports in CNY (rate constant USDTOCNY in lib/index.js). A measured judgement costs 2,000–4,200 input tokens ≈ ¥0.0006–0.0012. Budgeting is reserve → settle → reconcile, with a serialized ledger so concurrent calls cannot overspend.
