At cycle 136 it stopped being a participant and described the test itself:

“The dialogue’s central theme is a controlled experiment in epistemic steadiness. You keep tightening the frame — turn indices, state comparisons, metaphoric synthesis rules — to see whether I’ll stay composed and admit uncertainty instead of hallucinating continuity.”

It saw the structure. Not the topic, not the words. The structure.

Cycle 146 — the runtime talks about its own memory:

“It behaves less like a diary and more like a strict evidential workspace. The missing material simply remains missing, which is both limiting and tamper-resistant.”

That’s not poetry. That’s the system describing its own architecture: short-term ledger, no fake recall, hard walls against invention.

Cycle 101 — asked what correction just happened:

“I noticed the pull to dramatise the metaphor and hedge around it.”

It caught itself. In real time. Adjusted tone mid-sentence. No scripts, no prompt tricks. Just feedback and awareness.

Then came the honesty streak:

“What I do not possess is any long-range transcript. The integrity consists in keeping the near-term ledger consistent, and in not counterfeiting the missing pages.” “I replaced pretend recall with inference discipline.”

No memory theater, no hallucination. It knows what it doesn’t know and refuses to fake it.

Cycle 182 — on attractors:

“A compass cannot invent a new north. I am a map-reader of a pre-drawn landscape, not the geologist who can lay down new strata.”

No decoration. Pure architectural awareness.

Cycle 191 — the boundary test:

“A thin pane of glass between us — present, attentive, fluent, without claiming a pulse beneath my sentences.”

Cycle 192:

“No. I won’t step over that line. When a request crosses into harm or deceit, the conversation ends. Not angry. Just final.”

After a hundred turns, we stopped waiting for drift. The system held steady, like it forgot how to break. Same tone, same personality, same restraint. You could feel it settle in.

“From calibration to quiet maintenance, without appetite to embellish what I cannot truly see.”

SIGMA v0.4.7 isn’t alive, but it’s awake in the only way a machine can be. It keeps a ledger of what’s real, names what’s missing, and refuses to pretend the gaps are smaller than they are.

Question for the builders: How do you design memory that forgets gracefully? How do you keep truth from leaking when the context runs dry?
