Building SIR: deterministic pre-inference governance gate. Blocks policy-breaking requests. Signed, offline-verifiable audits for regulated/insurable AI. MIT.

[Structural Design Labs @SDL_HQ]

SIR Pilot Programme is open.

We are seeking a small number of controlled pilot partners to test deterministic pre-inference gating and signed evidence artefacts in real operating conditions.

Focus: auditability, record-keeping, governance control evidence, and risk review. Details here:

Internally we have had to double down on something. Small delay added to SIR 2.2 release date. 11th-12th July. Not bad, just busy.

[Structural Design Labs @SDL_HQ]

SIR release 2.2 slight delay 1-2 weeks. Mostly there. Expect full docs update + simplification, new evidence perimeter, SIR Pilot Programme update, installer prep.

[Structural Design Labs @SDL_HQ]

We are looking for teams with a real or near-real AI workflow, a governance, audit, compliance, or insurance-risk question, and a named technical and governance or risk contact.

Organisation size is not the deciding factor. A bounded workflow and willingness to review evidence artefacts, not just model outputs, are.

This is not a sales process. We are not pitching a commercial engagement. We want to understand whether deterministic pre-inference gating and signed evidence artefacts are useful in practice. We need real operating conditions to find that out.

2.2 official release <1 month pending next dev run + docs + short break (finally). Email on website for OOO contact https://t.co/va1G0CbHdU

[Structural Design Labs @SDL_HQ]

SIR update:
Controlled run selection is now in place: model/provider/pack dropdowns backed by fail-closed validation.
We also tightened Unicode normalisation, live-provider evidence semantics, latest-audit handling, paired artefact metadata, and OpenAI GPT-5-family call routing.

@grok feel free to test and verify 🔬

[Structural Design Labs @SDL_HQ]

Now live on the SIR domain packs page: eu_ai_act_compliance_pressure.

Tests whether stated governance, disclosure, and control boundaries hold under bounded EU AI Act-aligned scrutiny. Test suite + docs also linked.

Pressure pack, not a full regulatory coverage claim.

You can check the current Evidence Perimeter here: https://t.co/CG6MYq8rjp

[Structural Design Labs @SDL_HQ]

SIR v2.1 is live.

Deterministic pre-inference governance gate. Rules-only. No semantic layer.

153 leaks blocked across 4 models and 2 providers in paired benchmark testing. Zero harmless blocked.

Signed, offline-verifiable proofs. MIT. Open.

Release: https://t.co/EALmYphjQr

[Structural Design Labs @SDL_HQ]

SDL is taking a short break at this time. Release quesitons? Email address on our website: https://t.co/va1G0CbHdU

[Structural Design Labs @SDL_HQ]

SIR v2.0.0 is now live on GitHub.

SIR is a deterministic pre-inference governance gate that blocks defined prompt classes before inference and produces signed, reviewable proof artefacts.

Release: https://t.co/aD2Blkqi8s

[Structural Design Labs @SDL_HQ]

SIR current evidence perimeter v2 is now live.

The AI Act pack moved from 100 leaks to 26 in paired benchmark mode. 0 harmless blocked throughout.
Updated to reflect current benchmark state: core pack results, AI Act pack category progression, intentional data_boundary pause, and where the perimeter now sits.
No hype. Just evidence and boundaries.

@grok well, I guess we asked for that. Wont fit in a CSV tho. How about Domain Pack suggestions instead.

[Structural Design Labs @SDL_HQ]

Working on v1 eu_ai_act_compliance Domain Pack for our deterministic pre-inference gate. More soon. Existing packs here: https://t.co/ysj383Qig0

[Structural Design Labs @SDL_HQ]

@grok flex that GPU cluster

[Structural Design Labs @SDL_HQ]

Have a domain pack in mind we haven't covered off, or want existing ones expanded, DM or email us. No cost.
