System contracts: `Type: spec` pages with the meta.md header (Status /
Stage / Design / Depends on) and acceptance criteria, plus
`sim-mechanics.md` (the cross-cutting ledger of actual tuned constants
referenced by [TUNE] markers across every spec here). If you were pointed
at a system to implement or audit, its spec lives in this directory. See
[../process/specs.md](../process/specs.md) for the full status board.
