docs/PHASE4: analyze — surface confirmed, counter strategy locked
A1. history.lua surface lines up cleanly for the memory additions —
no structural refactor; pure additive functions mirroring the
session pattern.
A2. Counter persistence: scan at open, cache next_id in handle.
O(n) load (n bounded by curation, ~hundreds), no sidecar file.
Persisted ids let forget-tombstones target items even across
restarts.
A3. System-prompt suffix order locked: DEFAULT (carrying Phase 2 MCP
block baked in) → Phase 4 [background] → Phase 3 NORRIS. Token
cost measured: default ~174 toks, +NORRIS ~364 toks, +NORRIS+2KB
background ~865 toks. Well within typical context budgets.
No manifest amendments needed — §3/§5 already match. Findings recorded
inline as Phase 7 anchors.
