| // v0.14: MemoryConfig — the token thresholds for the M0–M3 memory layering. | |
| // | |
| // Principle 4 (v0.14 plan): MemoryConfig is a SEPARATE type, not a field on | |
| // ShellConfig. ShellConfig is about runtime guards (token / iter / toolRate / | |
| // time / errorRate). MemoryConfig is about information-flow layering. Mixing | |
| // them couples unrelated concerns and breaks the ADR-003 rule "shell has no | |
| // business fields". This type lives at the shell layer so the layered | |
| // projection (a shell concern) owns it. | |
| // | |
| // M1/M2 schema-sharing invariant (moved here from state-line/index.ts): | |
| // M1 and M2 currently share the 11-field CuratedMemory schema. M2 (summary | |
| // compression) is expected to diverge into a shorter form later; the layer | |
| // tag distinguishes them so a future schema split does not require a data | |
| // migration. Do not assume M1 === M2 forever. The thresholds below are the | |
| // only knob that decides WHICH layer a context lands in — the layer then | |
| // decides which schema is used for persistence, not the other way around. | |
