# AI crews for work that has to hold up. **AI crews for work that has to hold up.** Build, test and operate AI crews that cite their sources, name their approver and log every run.

Three failures stop AI being usable in regulated work. None is a model-quality problem, so no model upgrade fixes any of them. **No provenance** An answer with no traceable source is unusable in regulated work. You cannot cite it, you cannot defend it, and you cannot tell whether the underlying authority was superseded last quarter. **No accountability** When the output is wrong, the audit asks who approved it. “The model” is not an answer a partner or a licensed entity can give to a regulator or a client. **No regression control** A prompt change on Tuesday silently degrades output on Wednesday, and nobody finds out until a client does. There is no gate, no baseline and no way back. ## Three mechanics the model cannot talk its way around. Not guidance in a prompt. These are compiler and runtime properties, held outside the model, where a prompt injection cannot reach them. **Evidence or abstention** Every claim carries its sources, their authority and their dates. When retrieved evidence falls below the crew’s declared floor, the crew declines and names what is missing instead of guessing. Abstentions route to a knowledge-gap queue, not a failure log. [How evidence works →](/governance) **Autonomy is earned** Every crew launches at 100% human review. It graduates to risk-weighted sampling only on measured accuracy at a published confidence bound, and reverts automatically on breach. Regulated outputs stay at full review permanently. [See the autonomy stages →](/governance) **Nothing ships untested** Immutable Releases with locked dependencies, evaluation gates that block promotion, and a compiler that proves no untrusted input can reach an external action without an approval gate. [Inside the Runtime →](/runtime) An answer carries its sources, their authority and their dates. Below the crew’s declared evidence floor it declines and names the gap. A crew starts at full human review and climbs only on measured accuracy at a published bound. A breach sends it back down. > “We did not adopt this because it drafts well.

Reuse it. Run it. Three surfaces, one lifecycle, one versioned artefact underneath all of them — the Crew Manifest. **KrewOS Studio** Start from a proven Crew Template, configure it visually or describe the change in plain English. Every change becomes a versioned manifest with a visible diff before anything is applied. [Studio →](/studio) **KrewOS Hub** A curated catalogue of verified Agents, Pods, Crew Templates and licensed Packs. Use, configure or fork — with lineage tracked and dependency versions locked. [Hub →](/hub-product) **KrewOS Runtime** Durable execution that survives restarts, waits days for a human, never fires the same external action twice, and stops at your budget. [Runtime →](/runtime) One versioned artefact runs through all three surfaces, and every run writes back to it. ## Six crews in production. Every one is a template you can fork. These are not demos. They are wGrow’s own production systems, rebuilt on KrewOS and published as Crew Templates you can configure. **LawCrew** Jurisdiction routing, drafting, adversarial review and professional sign-off on document review. **Finance Close** Nested functional teams, reconciliation, exception handling and an approved workbook output. **AquaMind** Dynamic routing and an expert panel over farm telemetry, with safety gates and technical sign-off. **Content Studio** Long sequential production with retrieval, citations, bounded revision loops and bilingual output. **BizDev Intelligence** Parallel scouts, source verification, opportunity scoring and human promotion into CRM. **eCommerce Selection** Market and product research, scoring, creative generation and commercial approval. ## The jurisdiction knowledge is already in the box. A KrewOS Pack is a licensed vertical package — Crew Templates, Knowledge Packs, deterministic policies, evaluation datasets and dashboards, maintained and dated by the publisher. You are not starting with an empty canvas and a jurisdiction problem. **Singapore Legal Practice** Jurisdiction routing, SG clause libraries, privilege handling, dated currency assertions. **MAS Financial Compliance** Controls mapping, third-party and outsourcing policy packs, reconciliation evaluation sets. **Aquaculture Operations** Species and regional knowledge, water-chemistry rules, telemetry connectors, escalation routing. **SG Tender Response** Relevance classification, requirement extraction, capability-library drafting, submission checks. [Browse the Packs catalogue →](/trust/packs) ## Your compliance team’s questions, answered before they ask. The Trust Centre is in the primary navigation, not the footer. Procurement should not have to email anyone to start an assessment. The compiler proves it: no path exists from untrusted input to an external action that does not pass an approval gate.
