Local-only decision assurance workspace
Move from a GPU shortlist to a decision your review team can defend
Import a Decision Room dossier, resolve every non-compute cost and assurance gate, and generate a reproducible TCO, risk register, provider question set, and sign-off record. Unknowns remain unknown; the tool never invents private discounts, fees, capacity, performance, or contract terms.
- Base, downside, and burst TCO
- Technical, commercial, security, and procurement gates
- No account, upload, cookie, or server-side scenario storage
Deterministic review path
A consulting workflow encoded as evidence gates
Each stage fails closed. A lower visible rate cannot bypass an unresolved requirement.
- 1Anchor
Validate the source decision, fingerprint, catalog timestamp, candidates, costs, and official links.
- 2Complete TCO
Type every amount as quote, contract, official publication, buyer estimate, not applicable, or unknown.
- 3Challenge risk
Review performance, topology, recovery, capacity, SLA, security, compliance, residency, legal, and exit terms.
- 4Decide
Compare base, downside, and burst outcomes; resolve blockers; record accountable sign-offs.
- 5Preserve
Export the evidence register, questions, risks, boundaries, and triggers as JSON or Markdown.
Confidentiality boundary
Your file and edits stay in this browser tab
The selected JSON file is read locally. Its contents, cost assumptions, references, dates, gates, and sign-offs are not uploaded, added to analytics, placed in the URL, or stored by this tool. A downloaded dossier can contain sensitive commercial evidence: redact it before sharing and keep the original under your own access controls.
1 · Anchor the source decision
Import a Decision Room JSON dossier
Accepted schema: saas-sentinel/gpu-decision-dossier/v1. Maximum file size: 2 MB. Only a valid recommended result can enter assurance review.
Validated source
The decision anchor is internally consistent
- Decision fingerprint
- Engine
- Catalog generated
- Decision horizon
- Reviewable candidates
Optional · Preserve the provider evidence chain
Import a reviewed provider Assurance handoff
Accepted schema: saas-sentinel/provider-assurance-handoff/v1. Maximum file size: 512 KiB. Values are staged only; you must select and apply each proposal before it affects this assessment.
Import a Decision Room dossier first.

This provider is shortlisted but not in the current three-candidate assessment. Switching resets only the candidate evidence forms; no provider assertion is applied.
Buyer-selectable proposals
Unresolved facts and blockers
No checkbox is preselected. Applying records the handoff fingerprint in each accepted reference; it does not verify the provider or authorize spend.

Preferred within fully assessed candidates
Candidate readiness and fully loaded cost
Compute-only market evidence remains visible beside buyer/provider cost evidence.
Risk and missing-evidence register
Critical and high-severity items appear first. A blocker prevents that candidate from being ready.
Provider diligence questions
Use these questions to replace unknowns with attributable quote, contract, or official evidence.
Decision invalidation triggers
The dossier is a dated decision record, not a perpetual guarantee. Reopen it when any trigger fires.
Preserve the review
Export the complete local dossier
JSON preserves the machine-readable evidence register. Markdown creates a review memo for tickets, procurement records, or a human challenge. Inspect and redact either file before sharing.
