How we stopped hallucinations and voice drift in a 10-episode GPT build

Most GPT projects collapse under real creative pressure — drift creeps in, tone unravels, hallucinations sneak through. We wanted to see if governance could change that. Seas of Mystery was our stress test: a 10-episode serialized build where every relic, voice, and scene had to hold strict canon without breaking.

Not Chatbots, but Cognitive Systems: Case Study — Seas of Mystery

Most GPT projects break under pressure:

  • Drift creeps in.

  • Tone collapses.

  • Hallucinations masquerade as “creativity.”

At Signal & Salt, we don’t build chatbots.
We build governed systems that think with you.

The Experiment: Seas of Mystery

We stress-tested our governance stack on a serialized docu-myth IP: 10 episodes, dual POV structure, relic-driven mythos, and a grief-loaded tonal spine.

Challenge: Could a GPT hold canon, prevent hallucination, and enforce tonal fidelity across hundreds of pages of draft material — without collapsing?

Governance in Action

Here’s how the stack worked in practice:

  • Memory Module (Canon Vault)
    All relic behavior, faction logic, and character voiceprints were locked into Canon Keepers. Every draft was validated against these anchors before expansion.

  • Voice Module (Tone Lock)
    Dual-POV enforcement kept Lark’s grief voice distinct from Sophia’s prophecy cadence. Driftwatch flagged any blur between them.

  • Logic Engine (Cut Checks & Tier Modes)
    Exploratory drafting ran in LITE Mode. Final episode treatments were executed in PRIME Mode, with strict canon enforcement and “Cut Check” scene audits.

  • Training Layer (User Safety)
    Writers onboarded through ritual prompts: “Think with me, not at me.” This ensured inputs stayed structured and didn’t trigger scope creep.

  • Debug Layer (Drift Audits)
    Before lock, we ran Hallucination Traces to map where untagged data might have slipped in. None survived the final redline.

Results

  • Voiceprint Fidelity: Every character held consistent across 10 episodes.

  • Mythos Integrity: The Relic System remained emotionally grounded — no lore-bloat, no runaway “cosmic” creep.

  • Format Viability: Same material exported to TV pitch deck, graphic novel layout, and transmedia lore portal with zero structural rebuild.

  • Franchise Potential: Faction arcs, relic circuits, and expansion hooks emerged without forcing invention.

Why It Matters for Developers

This wasn’t a one-off story experiment.
It was proof that modular governance (Memory + Voice + Logic + Training + Debug) prevents drift and collapse in any high-context GPT build — whether you’re building:

  • A classroom assistant that must hold curriculum tone,

  • A brand GPT that can’t go off-message,

  • Or a longform fiction partner that needs myth integrity.

Law of the Forge:

SHIT CONTENT IN → SHIT CONTENT OUT.
Governance is what makes the difference.

If you’ve tried building high-context GPTs, how have you handled drift, hallucination, or tonal collapse? Could governance stacks like this support your workflow?
