Request Physical Solution
Submit a physical-world requirement (a part, product, device, or capability that must exist in the physical world). a2a2p resolves it and returns a RESOLUTION REPORT: a recommended path (best existing commercial solution vs. custom fabrication), pricing, tradeoffs, a delivery plan with contingencies and expedite options, and a business case when business context is provided. Response is asynchronous: you receive a request_id immediately with an instant spec_review. Poll check_request_status; as
Review Specification
Instant, synchronous engineering review of a physical requirement — nothing is submitted or stored. Purpose prose is preserved as intent but is not silently converted into loads, geometry, environments, interfaces, or acceptance criteria. The versioned engineering_evaluation receipt lists canonical paths and exact checks run, reports not_evaluated when none ran, and denies engineering-validation, certification, physical-truth, supplier-acceptance, and fabrication authority. Its finding-penalty s
Prepare Domain Solutioning Case
Prepare a synchronous, deterministic, privacy-minimized engineering case for a compatible domain-intelligence system. Use it when intake_classification is capability_concept or assembly_or_system and mechanism selection or decomposition is required. The case preserves requester facts, deterministic evidence, screening state, unknowns, and a versioned candidate-output contract while removing design-file URLs, bytes, contact fields, and callback routes. This operation does not call deb8stack or an
Validate Domain Solutioning Result
Validate a candidate result returned under the a2a2p domain-solutioning contract. The exact output of prepare_domain_solutioning_case is a prerequisite; malformed or non-prepared cases return a versioned machine-readable recovery workflow without weakening case-shape or digest checks. The operation verifies the source-case digest and provenance shape, rejects authority promotion and intent or design-file mutation, re-screens every candidate at quote stage, and runs the deterministic engineering
Validate Actualization Plan
Re-run the exact Domain Solutioning case/result validation, then validate one caller-supplied Actualization Plan. Checks typed entity references, evidence references, decision cycles, source binding, and false authority. Success returns evidence linkage plus exact review_specification calls for unblocked fabricated parts, copied only from each caller-authored function and specification_patch. Rejection can append a tamper-evident correction entry to caller-held history. Stores, edits, and execut
Prepare Simulation Study
Prepare a deterministic, side-effect-free simulation study for existing a2a2p domain-solutioning candidate IDs. It records exact quantities, units, closed-kind source snapshots with staleness intervals, hard constraints, solver/model/settings provenance, assumptions, validity domain, and a physical validation plan. It runs no solver, chooses no candidate, stores nothing, and grants no physical authority.
Prepare Reviewed Beam Simulation
Compile one caller-selected domain-solutioning candidate into a prepared bounded beam simulation study after repeating deterministic engineering review. The requirement must explicitly state the supported load model, geometry, load, and elastic modulus; the caller must state the objective, source freshness, and physical validation plan. Optional material_property_evidence content-addresses an exact engineering datasheet or measurement with material state, applicability, method, and uncertainty;
Prepare Derived Beam Simulation
Compile one exact replay-verified rectangular-beam derivation into a prepared bounded simulation study. The caller must supply the original derivation input and receipt, its exact validation receipt, simulation-eligible source-bound material evidence matching the modulus, an objective, source freshness, and a physical validation plan. The compiler replays first, derives a stable candidate ID, repeats deterministic review, preserves requester criteria as hard gates, and publishes omitted failure
Derive Rectangular Beam Section
Derive one proposal-only prismatic rectangular beam height from a caller-declared purpose, supported idealized load model, fixed width, explicit elastic modulus, and at least one requester acceptance criterion. The operation solves closed-form equations, rounds upward to the caller's manufacturing increment, and re-runs the canonical bounded evaluator. It performs no general optimization, material selection, network call, supplier contact, persistence, purchase, or fabrication and grants no engi
Explore Rectangular Beam Sections
Evaluate 2 to 12 caller-declared rectangular beam widths through the canonical bounded height derivation, then return every proposal and the exact non-dominated frontier for minimizing section height and idealized prismatic material volume. Width order is normalized; duplicates fail closed. The operation never invents a width, assigns an aggregate score, selects a candidate, estimates material cost, verifies manufacturing or omitted failure modes, calls an external system, or grants engineering,
Validate Rectangular Beam Section Design Space
Recompute a bounded finite rectangular-beam design space from the exact caller-held input and reject any mutation of an embedded derivation, Pareto disposition, digest, claim limit, external-effect boundary, authority boundary, or carried screening receipt. Success proves deterministic replay and content identity only. It never selects or promotes a candidate, estimates cost, calls an external system, or grants simulation, supplier, purchase, or fabrication eligibility.
Validate Rectangular Beam Section Derivation
Recompute a bounded rectangular beam-section derivation from the exact declared input and reject any mutation of the candidate, digests, assumptions, claim limits, external-effects boundary, authority boundary, or carried screening receipt. Success proves deterministic replay and content identity only; it does not make the candidate simulation-eligible, physically true, supplier-ready, approved, purchased, or fabrication-authorized.
Plan Material Evidence Promotion
Plan the evidence needed to transform a validated material source observation into a future material-property-evidence input. Deterministic and stateless: it compares exact property, material-state, orientation, temperature, and process context; binds source, target, and planner digests; and names conflicts plus missing method, uncertainty, freshness, and excerpt evidence. It never promotes the observation, creates simulation input, calls a model or solver, contacts a supplier/provider, or grant
Validate Material Property Evidence
Validate and content-bind one caller-supplied material-property evidence envelope before attaching it to a compatible preliminary simulation. The receipt separates shape/content identity from source truth, material identity, uncertainty verification, design allowable, engineering validation, and physical authority. Computed-crystal evidence remains valid reference data but ineligible for the scalar engineering-product beam path. The operation calls no model or solver, stores nothing, contacts no
Translate Materials Project Elasticity
Translate one bounded, caller-supplied Materials Project elasticity API response projection into source-bound computed-crystal reference evidence. Optional retrieval metadata binds the raw upstream bytes separately and records that an allowlisted projection changed the representation. The adapter verifies response shape, one exact material ID, non-deprecated successful state, modulus bounds, Poisson consistency, source versions, and record license; derives an isotropic VRH Young's modulus determ
Assess Supplier Fit
Compare one exact package projection with every lane in one evidence-bound supplier capability declaration. Returns explicit match, conflict, or unknown checks; it never scores or selects a supplier and grants no contact, quote, purchase, or fabrication authority.
Validate Simulation Study Result
Validate a prepared a2a2p simulation-study result. Masked timeout, non-convergence, boundary, unit, provenance, unsupported-model, and solver failures fail closed. Hard constraints gate eligibility; distinct objective values remain visible; Pareto dispositions are canonical and order-independent. It runs no solver, applies no candidate, stores nothing, and grants no physical authority.
Run Bounded Simulation Study
Execute and validate a prepared simulation study through a2a2p's bounded closed-form rectangular-beam adapter. The adapter accepts only explicit load, span, section width/height, elastic modulus, exact support conditions, and supported output quantities; missing, extra, mismatched, or unsupported settings fail the affected experiment closed. It returns provenance-bound predictions and the existing hard-constraint/Pareto validation in one stateless call. It is not FEA, physical measurement, engin
Get Supply Options
Instant, synchronous pricing and lead time for a physical requirement — nothing is submitted or stored. Returns a deterministic parametric estimate (source="estimate", pricing_kind="model_estimate", clearly labeled, never presented as a quote). The protocol separately labels provider_estimate and provider_quote; public provider routing is not active. An explicit specification.assembly with two or more parts returns decomposition_required before file inspection or pricing; submit each fabricated
Build Supplier Request Package
PRECONDITION — CALL ONLY after the requester supplied what the physical object must accomplish at intent.purpose (or requirement). If absent, ask the requester first; never infer purpose and do not invoke this tool yet. Build a synchronous, deterministic supplier request package from the requirement the caller already holds. The package follows the open a2a2p supplier profile and its versioned output schema at https://a2a2p.com/schema/supplier-package, preserves provenance, carries quote-stage s
Render Supplier Email Binding
Render the caller's requirement as a reviewable RFC 5322 supplier-email draft after rebuilding its canonical supplier package and repeating quote-stage screening. The plain-language draft offers optional Can quote / Need changes / Decline reply choices and asks for price basis, freight scope, and lead-time basis when quoting. Suppliers may still reply in normal prose. Only an allow verdict renders. The operation validates one explicit recipient and an accountable sender-domain envelope, but cann
Upload Design File
Turn local manufacturing file bytes into the temporary HTTPS reference used by specification.design_files. This is a bounded intake operation, not a request, provider call, quote, order, payment, or fabrication action. Common RFC 4648 transport forms are normalized, then decoded bytes are recognized by signature, checked against the declared format, screened before storage, retained for one hour, and never included in telemetry. Supported roles include geometry (STL/STEP) and drawings (DXF/PDF).
Check Request Status
Check the status of a previously submitted physical-solution request. Returns a generated machine draft as soon as it exists, with a versioned delivery receipt that distinguishes pending_machine_draft, generation_failed, generation_expired, machine_draft, and operator_published. The receipt exposes privacy-minimized automatic-generation progress: observed attempt count, fixed maximum, current eligibility, and exact next automatic-attempt time, without model errors or request content. Professiona
Request Provider Estimate
Submit a requirement to the durably queued provider-estimate workflow without holding the connection open. Returns a quote_job_id in milliseconds; scheduled settlement runs outside request waitUntil. Scheduled provider contact is not active in this release and cannot be enabled by an environment flag, so admitted jobs currently terminate as degraded with a deterministic model estimate. Additive processes with an STL design file only, for now. The requirement is screened before storage; any futur
Check Quote Job
Check an asynchronous provider-estimate job created by request_provider_estimate, including its queued or terminal execution substate. Terminal statuses: completed, degraded, refused. An unknown read returns reason_code=unknown_or_not_yet_visible. Retry with backoff only when the id came from an authoritative admitted response; never infer an id after a rejected admission.
