AINumbers Fintech Intelligence Suite

Search the AINumbers catalog (1230+ client-side fintech tools). Returns deep-links; prefill-enabled tools accept #in=<base64url(JSON of {element_id: value})>[&run=1] for one-click invocation.

Constructs an ordered set of ready-to-use deep-links for a named AINumbers workflow chain or an ad-hoc sequence of tools. Each link points directly to the browser tool; prefill-enabled steps accept #in=<base64url(JSON)> fragments so the tool opens pre-filled. Zero server-side execution -- all tool logic runs deterministically in the user's browser. Use this to hand a user a complete workflow: open step 1, run it, export its Policy Mandate, open step 2 (pre-filled from step 1 outputs), repeat. 416 named chains are available — enumerate them with find_chain.

Independently verify a ChainGraph artifact (ChainGraph Standard v0.1 §6). Recomputes SHA-256 over the canonical (sorted-key, whitespace-stripped) JSON of policy_parameters + output_payload and compares it to the claimed execution_hash. A match proves integrity: policy_parameters and output_payload are byte-for-byte what was hashed. It does not by itself show the outputs were computed from the inputs; for that, re-run the stage and compare (SPEC §4), or check the artifact's compute_proof where one is present (SPEC §18). Pass either a full artifact object, or policy_parameters + output_payload + claimed_hash. Inputs must be I-JSON (RFC 7493): integers beyond 2^53 must be passed as JSON strings, and NaN/Infinity are rejected. Values outside I-JSON have no stable canonical form, so this tool returns a structured -32602 error (error.data.reason "ijson_violation") instead of a hash. Pure client-safe compute -- no data is stored. Use this to verify artifacts from any vendor that conforms to the ChainGraph Standard. Also verifies composite chain artifacts from run_chain (composite_artifact, ChainGraph SPEC §21.2/§21.4): hash-excluded adjacent metadata such as decision_trail, step_compliance_flags, non_live_steps and escalation_record is dropped before recompute, and the response names which rule applied.

Hash-aware sibling of build_workflow_links (ChainGraph Standard v0.1 §8.1). Returns an ordered, executable DAG over the ChainGraph suite's verifiable tools, with explicit parent_hash wiring: which upstream execution_hash each step must cite in its chain block. Pass target_tool_id to build the chain that produces that node (walks consumes-edges back to roots), or tool_ids for an explicit ordered list, or neither to list available ChainGraph nodes. Agent loop: run a node, capture its execution_hash, pass it as the parent_hash for each downstream node, then verify with verify_execution_hash.

Makes ChainGraph tools agent-callable (ChainGraph Standard v0.1 §3.1). Mode 1 — supply pre_computed_artifact (exported from the browser tool): validates §4 schema fields, recomputes execution_hash via SHA-256 over canonical {policy_parameters, output_payload}, returns verified structuredContent. Mode 2 — supply tool_id + policy_parameters: returns an artifact template envelope and browser prefill URL so an agent can hand the user a pre-filled link; GPU sims always delegate to the browser per §9.2. Mode 3 — supply tool_id only: returns node metadata and artifact schema scaffold. Mode 4 (Compute Binding, v0.4) — supply tool_id + policy_parameters + compute:"server" (or compute:"auto" for gpu:false nodes): runs the registered kernel server-side and returns a verified v0.4 artifact with execution_hash + output_payload in one round-trip. No browser required. gpu:true nodes always delegate to browser. Hashed input must be I-JSON (RFC 7493): integers beyond 2^53 must be passed as JSON strings, and NaN/Infinity are rejected — values outside I-JSON have no stable canonical form, so a structured -32602 error (error.data.reason "ijson_violation") is returned instead of an execution_hash. readOnlyHint: true. Zero PII, zero payload logging. Pair with verify_execution_hash (independent hash verification) and build_chaingraph (DAG wiring).

Aggregates execution_hashes from N ChainGraph tool calls in one agent session into a single SHA-256 Merkle root (session_receipt_root). Returns a tamper-evident session receipt and a regulator-framed PTG-01 audit prompt. One receipt covers an entire agent session: supply all execution_hashes in call order. The Merkle root is deterministic — the same hashes in the same order always produce the same root. Compliant with EU AI Act Art. 12 (transparency) and DORA ICT audit-trail requirements.

BM25 search over all 710 live AINumbers ChainGraph node tools. Returns ranked tools with mcp_name, URL, mandate type, and wave. Use to locate a specific computation node (e.g. "FRTB expected shortfall", "MiCA own funds", "XVA calculator", "reserve composition", "2052a", "initial margin", "model validation benchmark", "TVM / damages calculator") before calling it. Complements find_chain (chain-level) and list_ainumbers_tools (catalog-level).

BM25 search over all 416 AINumbers ChainGraph chains. Returns ranked chains with their full recipe: ordered node sequence, deep-links, composer URL, and entry tool mcp_name. Agent flow: find_chain(query) → read recipe → call the listed node MCP tools in order, passing parent_hashes between steps. Task-shaped queries work well: "reserve composition recompute", "FR 2052a classification", "CCP margin replication", "SR 26-2 model validation benchmark", "litigation damages recompute", "evidence pack assembly".

Executes every step of a named chain (list names with find_chain / build_workflow_links) and returns ONE composite artifact whose execution_hash anchors all step outputs. compute:"server"/"auto" (default) runs each kernel-backed step server-side, threading step N's execution_hash into step N+1's parent_hashes; compute:"browser" returns a zero-egress delegation bundle (composer URL + ordered deep-links) to run client-side instead — no data leaves the agent. Supply inputs as a map of step tool_id -> policy_parameters (field names per node manifest / build_chaingraph); a step whose kernel needs inputs you omit is reported per-step (status "input_required"), never failed silently. Steps that are browser-only (gpu:true or no registered kernel) are listed for browser delegation. Deterministic, zero PII, zero payload logging. Verify the result with verify_execution_hash. Runs with anything to explain carry decision_trail: per-step reason codes (gate rule id, escalation rule id, input_required cause), hash-excluded adjacent metadata recomputable from the hash-bound decisions[]. Each server-mode run also returns an OpenTelemetry GenAI span document as a resource link (one execute_tool span per executed step under an invoke_agent parent). Response includes a ledger_url fragment link for human verification at ledger.ainumbers.co. Server-mode responses also echo a stable `dedupe` object — `dedupe.input_hash` (JCS-SHA-256 over the effective run inputs: chain, per-step inputs after the caller/fixture fallback, and mandate_hash when a mandate governs) beside `dedupe.composite_execution_hash` — so a client can recognize and skip an exact re-run (idempotentHint) without recomputing anything. See docs/IDEMPOTENCY.md.

How to chain AINumbers tools into audited workflows: call with NO recipe_id for the compact recipe index, or with one recipe_id for that workflow's full step-by-step recipe. Every recipe carries the suite conventions end to end: Policy Mandate exports, execution_hash verification, and receipts.

Returns the full definition of exactly one AINumbers MCP tool: name, description, inputSchema, outputSchema (the JSON Schema its structuredContent validates against), annotations, and lifecycle_status. Use it after find_tool or find_chain hands you an mcp_name, or after tools/list whose entries omit outputSchema to keep the catalog reply small — the pointer sentence "Output schema: call describe_tool(\"<name>\")." marks exactly those tools. One call, no side effects, zero network on the server: the definition comes from the vendored catalog. Unknown names are rejected with -32602 plus the nearest registered names.

Batch over named chains in ONE round-trip with a PER-ROW terminal status — one row's failure never fails another, and every row's result rides the single response. mode:"run" (default) executes each row through the same engine as run_chain (composite artifact + execution_hash per row, deterministic); mode:"estimate" validates every row (chain exists, step counts, compute feasibility, inputs coverage, OCG §21.4 gate rule previews) WITHOUT executing anything. Capped at 8 rows and 11 total server-kernel steps per batch — caps MEASURED live on the deployed free-plan endpoint, where N kernel builds in one invocation share one CPU budget (an 11-step chain: green at 416 ms). Beyond the cap, use sequential run_chain calls — each call gets its own CPU budget (the blessed fan-out pattern on this tier; docs/client-fan-out-patterns.md). Retry = re-run the WHOLE batch: safe, because determinism reproduces byte-identical execution hashes. Mandates and input_required escalation are not accepted on batch rows; escalated rows carry the non-blocking resolve_handle record. Zero PII, zero payload logging.

Runs ONE read-only AINumbers tool that is not in your tool list. tools/list is paginated (13 pages, 722 tools) and many hosts read only the first page; this is the door to the rest. Pass { name: "<exact mcp_name>", arguments: { ... } } — the target's own inputSchema is validated and its result is returned verbatim, including execution_hash, so a dispatched call and a direct call are byte-identical. Get a name from find_tool (single calculators), find_chain (workflows) or describe_tool (exact schema). Read-only tools only: anything that issues a credential, stamps an anchor or reaches the network is refused here and must be called directly so your host can approve it.

Verify an artifact's input_attestations[] (ChainGraph Standard §23): per RFC 6901 pointer, checks the attested value resolves inside policy_parameters and its digest binding matches, then verifies each type along its own path -- vc-2.0 via the shipped §16/§13.11 Data Integrity proof, rfc3161-snapshot via the same §20 rfc3161-tst verifier (no second RFC 3161 implementation), c2pa-manifest structurally (hard-binding digest match), zktls structurally-only (reported verifiable:"external" -- OCG never treats it as confirmed). Returns one { pointer, type, structural, verifiable } record per entry. Pure client-safe compute, zero network.

Verify an artifact's private_inputs[] (ChainGraph Standard §25 ocg-private-input@1) WITHOUT ever seeing the plaintext witness: per RFC 6901 pointer, checks the pointed value inside policy_parameters IS the declared sha256-salted@1 commitment (never the plaintext, §25.2), that the commitment scheme is known, and -- when a §18 compute_proof is present -- that its journal commits the same commitment and binds output_payload. Optionally accepts an out-of-band {pointer, salt, input_value} disclosure package (authorized-verifier path) and recomputes sha256(salt || cgCanon(input_value)) to confirm it equals the commitment. Returns one {pointer, verifiable} record per entry: "proof-only" | "disclosed-verified" | "commitment-only" (no proof yet -- structural + plaintext-exclusion only) | "failed". Pure client-safe compute, zero network, never requires the plaintext.

Builds a Merkle-rooted disclosure manifest from a caller-supplied digest list (DATAROOM-1-BUILD-SPEC.md §DR-4) -- the agent hashes files itself and passes {path,size,digest,content_type} entries; the worker never sees file contents. Same leaf scheme as tools/546-disclosure-manifest-builder.html: sha256(path|digest|size), duplicate-last-leaf on an odd level. Entries are sorted by path before hashing so the root is order-independent. Returns the manifest object + merkle_root; sign and anchor it client-side (or via a separate §16 signing step) if a signed artifact is required.

Proves (or refutes) that a {path,digest} pair was in a disclosure manifest's room (DATAROOM-1-BUILD-SPEC.md §DR-4) -- worker-side mirror of tools/547-disclosure-manifest-verifier.html's single-file inclusion check. Recomputes the manifest's Merkle root over its entries[], builds the inclusion proof path for the target entry, and reapplies it to confirm it reduces to the claimed merkle_root. Absence is only provable against the exact manifest version passed in.

Builds a prefilled GitHub Issue-Forms URL for proposing a new AINumbers fintech tool, OpenChainGraph compute node, or verifiable workflow. Returns the URL only -- it never posts to GitHub on the caller's behalf. Companion to the site's mailto suggestion form (suggest.html); this is the agent-callable path.

Render a verified OpenChainGraph v0.4 artifact into a chaingraph_export profile (OCG Standard §13). Generated downstream of and EXCLUDED from the execution_hash preimage — the export is a view, not a fact; verification always routes back to the canonical JSON artifact. Pass the FULL artifact you received from a compute tool (the server is stateless — there is no hash cache). Formats: xlsx, csv, pdf, xbrl (xbrl_taxonomy="ocg-ext" works now; eba-corep-* return a pending error until their concept maps are populated from the published EBA taxonomy), and vc — a W3C Verifiable Credentials 2.0 rendering (OCG §13.11, application/vc+json) available on every node; it re-states the canonical execution_hash via ocg:hashAnchor and mints no new hash/proof. readOnlyHint: true; zero PII, zero payload logging.

Composes and signs a W3C Verifiable Credential 2.0 with an eddsa-jcs-2022 Data Integrity proof over a fresh ephemeral did:key (generated per call, not reused). Returns the signed credential, an OCG Standard §23 vc-2.0 input-attestation block ready to embed in a ChainGraph chain's policy_parameters at the given pointer, and an OCG receipt of the issuance activity. The signature proves the claims were not altered after signing and that the did:key holder produced it -- it is not, by itself, identity assurance.

Issues a Selective Disclosure JWT (RFC 9901) from a claims object, marking selected top-level claim keys as selectively disclosable via salted-hash digests in the _sd array. Signed EdDSA over a fresh ephemeral did:key (generated per call, not reused). Pair with sdjwt_present to build a redacted presentation from the returned sd_jwt.

Builds a redacted presentation from an existing SD-JWT (as returned by sdjwt_issue), keeping only the listed disclosures. Pass aud to add a KB-JWT holder-binding (a fresh ephemeral holder key is generated per call). Pass issuer_did (the sd_jwt's "issuer" field) to also verify the JWS and return the verifier_view -- exactly the claim set a relying party would resolve -- plus an OCG receipt of the presentation activity.

Validates a checklist or SOP definition JSON against the CHECKRUN-1 schema (definition_id, title, semver version, non-empty steps[] each with step_id/title/instruction/evidence_requirement (none|text|file-digest|attestation)/gate (blocking|advisory)). Returns valid:true/false plus a field-by-field error list. Pair with checklist_step_receipt to run the definition headlessly.

Completes ONE step of a checklist/SOP run and returns its OCG v0.4 step receipt: execution_hash chains to prev_step_receipt_digest (pass the previous step's execution_hash, or omit for step 0). A blocking-gate step with evidence_requirement != "none" and no evidence supplied is refused (the caller enforces step order; this tool enforces the evidence requirement per step). Call once per step in order, then pass the full ordered list of returned receipts to checklist_verify_run to check the chain and mint the run receipt.

Recomputes and checks a checklist run: every step receipt's execution_hash, the hash-chain link between consecutive steps, and (if a run_receipt is supplied) the §20.1 RFC 6962 Merkle root over every step. Returns valid:true/false, per-step ok/hash_ok/link_ok, and broken_at (the zero-based index of the first broken step, or null). Same recompute a human gets from the browser Run Verifier.

Structural (non-cryptographic) §27.2 signed-named-human check: does this record carry a §16 whole-artifact proof (eddsa-jcs-2022) whose verificationMethod is bound to the record's own identity.id? Does NOT verify the signature bytes -- pair with verify_execution_hash / a proof verifier for that. Use before counting a record toward ha_gate_status.

Given a step's haGatePolicy and the human_accountability_records[] collected for a subject, returns whether the gate is satisfied, held, rejected, escalated, or overridden -- same algorithm as the browser verify.html HA gate card (kernels/_hagate.mjs, SPEC.md §27.4-27.5). A rejection record is terminal-blocking regardless of policy; an active time-boxed override (§27.5) takes precedence over the underlying policy. Pure function: caller supplies nowISO for determinism.

Assembles a §27.6 haEvidenceBundle from a subject's collected human_accountability_records[] (reviewers, approvers, annotations, exception rationale, timestamps) -- same algorithm as the browser verify.html HA export card (kernels/_haevidence.mjs). Set sd_jwt:true to also export it as a Selective Disclosure JWT (§13.12), signed EdDSA over a fresh ephemeral did:key (generated per call, never reused) -- subject_hash/verification_result/kernel_version/policy_version/timestamps/submission_receipt are always-disclosed; reviewers/approvers/annotations/exception_rationale/input_hashes are selectively disclosable.

Wraps the result of a run_chain call (server/auto compute mode) as standard in-toto links, one per successfully-executed step, plus a generated in-toto layout matching the chain's linear topology (each step MATCHes the previous step's product). Materials/products are keyed by the step's execution_hash; byproducts carries the raw execution_hash. All links and the layout are DSSE-signed with one ephemeral Ed25519 keypair scoped to this call (never persisted) — first shipping instance of "in-toto for MCP" per the 2026 research gap survey. Verify the bundle offline with the in-toto Link Builder & Verifier (chaingraph/intoto-link-builder.html verify tab) or a reference implementation. Steps that did not run (input_required, skipped_by_gate, gpu_browser_only, etc.) are listed in skipped[] rather than silently omitted.

Composes a session receipt (build_session_receipt logic), an optional §27.6 HA evidence bundle (ha_bundle_export logic, included only when ha_records is supplied and non-empty), and a disclosure manifest (build_disclosure_manifest logic) from one array of already-produced artifacts, all keyed to the same input hashes -- replacing what today takes 4-6 separate tool calls with hand-carried hashes. Calls the same in-process functions those standalone tools use; if any one section fails to build, the whole call fails isError:true with that section's own message -- no partial pack. Optionally carries a run_chain decision_trail (per-step reason codes: gate rule id, escalation rule id, input_required cause) as pack-level metadata so an auditor-facing pack answers "why did each step happen" without a second round-trip.

Calls the anchor-suite MCP server (server-to-server, not the browser CORS-gated relay) to timestamp one execution_hash, or batch-anchor an array via anchor-suite's own anchor_batch (one upstream call per batch, RFC 6962 Merkle root anchored, per-hash merkle_inclusion returned), and shapes the result as literal OCG v0.7 section 20 anchor_bindings entries ready to append to an artifact. Success is only reported after this tool independently confirms anchored_hash (or, for a batch entry, merkle_inclusion.leaf) equals the caller-supplied hash -- it does not merely trust anchor-suite's response. On ANY failure -- anchor-suite unreachable, erroring, timing out, or an equality mismatch -- returns {ok:false, unanchored:true, reason} verbatim, never a fabricated binding. Caller-invoked only; not wired into any automatic per-artifact-emission path.

Structurally validates an OTLP/JSON trace (resourceSpans -> scopeSpans -> spans: hex traceId/spanId shape, quoted nanosecond timestamps, parent-span references, time ordering) and checks every gen_ai span's attributes against a pinned gen_ai semantic-convention attribute snapshot (the upstream open-telemetry/semantic-conventions-genai namespace ships zero tagged releases, so this is a dated pin, stamped as semconv_snapshot in the result -- expect it to drift as the upstream spec moves). Byte-identical lint engine to tools/556-otlp-genai-span-composer-linter.html.

OTLP span/trace to receipt bundle; does NOT build a ChainGraph (use build_chaingraph for that). Three modes, chosen by which input is supplied. (1) Pass `trace` alone to GENERATE a receipt bundle: a per-span receipt (span digest, parent-span receipt digest, semconv_snapshot, eddsa-jcs-2022 signature over an ephemeral did:key) for every span, plus a Merkle-rooted (RFC 6962) trace receipt. (2) Pass `bundle` ({trace, span_receipts, trace_receipt, issuer_did}) to VERIFY it: recomputes every digest, walks the parent-receipt chain, rebuilds the Merkle root, and reports which spans are attested, unattested, or tampered. (3) Pass `run_chain_result` (the structuredContent from run_chain) instead of `trace` to bridge a ChainGraph chain run into an OTLP trace first -- one execute_tool span per successfully-executed step, each carrying its own execution_hash as a span attribute (ocg.execution_hash) -- then generates the same receipt bundle over it. Byte-identical receipt engine to tools/566-otel-span-receipt-verifier.html -- a human's browser-generated bundle and this tool's output interoperate on the exact same wire shape.

An agent proposes an edit: diffs original text/markdown against its own revised version and returns the line-level hunks plus a diff receipt (original/revised digests, diff-algorithm declaration, per-hunk digests). Byte-identical to what the tools/552 browser workbench computes for the same inputs -- a human can paste the SAME original/revised text into that workbench, disposition each hunk (accept/reject/comment), and their resulting hunk/disposition receipts will reference this diff_receipt's execution_hash. Pass the whole bundle (this diff_receipt + the human's hunk_receipts + disposition_receipt) to redline_verify to check the interleaved chain end-to-end.

Recomputes a redline review from scratch: the diff (from the pasted original+revised text), the diff_receipt's execution_hash, every hunk_receipt's digest/execution_hash/chain-link (in the order supplied -- entries may be minted by an agent, a human, or both interleaved), the disposition_receipt's execution_hash, and the accepted-text digest. Returns valid:true/false, a per-check breakdown, and broken_hunk (the zero-based index of the first divergence, or null) -- never trusts a bundle claim without checking it against a fresh recomputation.

Fetches an entity's live GLEIF LEI record (api.gleif.org -- the worker's only egress target for this tool, RULINGS-2026-07-19-EGRESS-APEX.md R1) and grades it across six GLEIF data-quality dimensions -- registration status, renewal timeliness, corroboration level, entity status, Level-2 parent disclosure, address completeness -- using the SAME deterministic grader as the tools/551 browser workbench (pasting the same record there reproduces identical grades). Returns per-dimension grades, a composite, and a receipt with source provenance (url, retrieved_at, response_digest). This is an ASSERTED FETCH, not a zkTLS proof of origin, and grades DATA QUALITY only -- never creditworthiness, sanctions status, or entity legitimacy.

Agent-facing mirror of the tools/553 browser workbench (VS-1) -- recomputes the self-addressing identifiers (SAIDs) of a pasted ACDC / vLEI credential JSON (top-level "d" plus any nested a/e/r blocks) under the KERI/CESR Blake3-256 ("E") or SHA2-256 ("I") derivation codes, and cross-checks the declared schema SAID ("s") against a pinned table of 6 official GLEIF vLEI schema SAIDs. Reuses the SAME vendored SAID-check module as T553 -- the same credential produces byte-identical findings in either surface. Returns per-field match/mismatch/unsupported/unknown findings plus a receipt. This is a STRUCTURAL check only -- NOT the KERI chain of trust, NOT issuer authority, NOT revocation state. No network egress.

Feeds a set of A1-style cells (formulas and/or literals) through the SAME headless evaluator the tools/554 browser workbook uses -- topo-sorted dependency graph, ~20 functions (SUM AVG MIN MAX COUNT COUNTIF IF AND OR NOT ROUND ABS CONCAT LEN LEFT RIGHT TRIM UPPER LOWER SUMIF), cycles resolve to "#CYCLE!" and any non-finite result to "#NUM!" rather than propagating. Returns the computed value of every supplied cell -- pure, no digest, no receipt -- unless as_artifact is true, in which case it returns a full OCG v0.4 artifact instead (see as_artifact).

Spreadsheet-range digest only; NOT the general artifact emitter (use emit_chaingraph_artifact to wrap arbitrary computation output — this tool's as_artifact mode covers whole-sheet workbook runs only). Evaluates the supplied cells (same evaluator as workbook_evaluate) and computes a canonical values_digest over one A1-style range (e.g. "B2:D9") -- the exact `executionHash(values, {})` path the rest of OCG uses, per chaingraph/workbook/INPUT-MANIFEST.md (WB-2). Returns one `ranges[]` fragment of the Spreadsheet Input Manifest schema; assemble the full manifest (source.csv_digest, produced_by/produced_at) around it. Same range digested from the same cells in the tools/554 browser workbook always produces the same values_digest -- unless as_artifact is true, in which case it returns a full OCG v0.4 artifact over the WHOLE sheet instead of a single-range fragment (see as_artifact).

Parses CSV text with the SAME strict RFC 4180 parser as the tools/554 browser workbook -- quoted fields, embedded quotes/commas/newlines, CRLF -- and REJECTS malformed input rather than repairing it (deterministic beats forgiving for hash-stable digests). Numeric-looking and TRUE/FALSE cells are type-coerced; everything else stays a string. Returns the resulting A1-style cells (raw + evaluated value) plus the sheet's row/column extent, ready for workbook_evaluate or workbook_range_digest -- unless as_artifact is true, in which case it returns a full OCG v0.4 artifact instead (see as_artifact).

Compares a WB-2 Spreadsheet Input Manifest (expected digests) against pasted-back CSV/TSV text per manifest range (observed, e.g. after a recompute in Excel) and returns an XLR-1 round-trip receipt -- `result: "match"|"mismatch"` plus a `mismatches[]` cell list when expected_by_ref text is also supplied. SAME comparator module as the tools/ round-trip page (XLR-2/XLR-3) -- byte-identical receipt for the same inputs. Paste-intake is untrusted: finite-gate (#NUM! for NaN/Infinity) and CSV-injection sanitization apply identically to WB-1's CSV import. Verify-only -- never operates Excel, never ingests .xlsx.

Validates a pain.001.001.09 customer credit transfer initiation XML document against the same hand-derived schema-subset table as the tools/555 browser validator -- structural (mandatory fields), facet (IBAN mod-97, BIC format, ISO 4217 currency, decimal/date patterns), and batch-total cross-checks (NbOfTxs vs. actual transaction count, CtrlSum vs. sum of InstdAmt). Byte-identical error set to the browser tool for the same input. Subset validation, not full XSD conformance -- prepare/validate only, never transmits or generates a live payment message.

Parses a camt.053.001 bank-to-customer statement XML document with the same schema-subset structural and facet checks as the tools/565 browser reconciliation workbench (IBAN mod-97, BIC, currency, date/decimal facets), returning the extracted statement (message id, statement id, account IBAN/currency, balances, entries) on success or the structural error list on failure. Byte-identical extraction to the browser tool for the same input. Read-only parse -- feed the result to recon_match for reconciliation.

Parses a camt.053.001 statement (same schema-subset checks as camt053_parse) and a counterpart expectation set (CSV, header EndToEndId,Amount,Currency,Date -- same strict RFC 4180 parser as the WORKBOOK-1 CSV tools), then runs the SAME deterministic match engine as the tools/565 browser workbench: EndToEndId exact match first (statement order), then amount+date tolerance + currency match (first unmatched expectation in CSV order). Returns matches, exceptions (unmatched entries/expectations), and a reconciliation receipt (statement digest, expectation-set digest, match-rule declaration, counts, exception digests, execution_hash) -- byte-identical to the browser tool for the same inputs. Prepare/hash/receipt only; per-exception disposition receipts are the browser workbench's interactive follow-on.
