The substrate is a dependency-free Python memory-and-activation substrate. What it shows is that its lower layers are correct and deterministic. It makes no claim that any layer reproduces a cognitive effect.
Three attempts to grade a cognitive effect were stopped before any graded run, each at a structurally distinct wall: semantic priming was circular, the fan effect found the mechanism absent, and interoception found the signal flat. The finding is scoped to this substrate and these three yardsticks. The recurring obstacle, an external yardstick that the project did not author, is the lesson stage 2 is built around. Its behavioural paradigms are published, and its baselines are reproduced against their published behaviour; the agent-side operationalisation and the pass criteria are the project's own and are pre-registered privately.
Build status
Bricks
Each brick of the substrate with its build status, as the ledger records it, and its meaning verdict. The two are separate axes: a brick can be built and verified while no meaning verdict has been earned.
Brick names such as “the depression path” name mechanisms in the substrate, not clinical models.
Build status
Is the mechanism built, and verified?
- Verified7 bricks
Deterministic, integrity-preserving and pure, verified in a separate tester pass.
Ledger status
PROVEN: verified by the full adversarial suite on every interpreter; not a formal proof. - Built9 bricks
Meaning not validated. The mechanism is tester-verified; no cognitive claim is made.
- Designed13 bricks
Specified only, not built.
Meaning verdict
Does it reproduce a cognitive effect, judged against external data?
- Not earned29 bricks
No meaning verdict has been earned. The meaning bar is open.
- No-go2 bricks
Stopped before a graded run. Attempts at a cognitive claim stopped before any graded number existed, each at its own wall: a circular yardstick, or a mechanism the effect needs that the engine lacks.
