Mechanism Matrix — seven layers, one record
Architecture of the outbound rail
Every layer states what enters, what it decides, and what it can never do.
The rail is not one model answering one question. It is seven layers, each with a single responsibility, a named owner, a declared technology and a failure position. A layer may only pass forward what the layer before it sealed.

Sequenced layers
Each one seals its output before the next may read it.
9 min
End-to-end clearance
Against 28 days across five parties working in sequence.

Model in the path
Statutory drafting only. Rule code holds every veto.
100%
Checkpoints proved
Every layer commits a hash-chained, verifiable artefact.

Clearance
This packet will sit for about 21.9 minutes — evidence, not the corridor, is the delay.
Recommended action
Close the 3 open evidence items before release.
Each missing document converts an engine-cleared check into an officer-signed one, which is the only step measured in hours.
Clearance falls to roughly 11.8 minutes.
Also forecast on this desk
The corridor prices at about 1014.01 bps all-in, treaty withholding included.
watchp50 1,014.01 bps · p90 1,024.91 bps — Put the ticket to a second AD bank and quote 8 bps.
Layer by layer
One chain. Open a layer to see its contract.
Input, action, output, technology, owner, and the position it takes when something is unclear. Nothing in the rail operates without all six being stated.
Layer chain — live 3D rail
Each node is one layer. The packet only moves once the layer before it has sealed its artefact — click a node, or open a layer below, and both stay in step.

Who acts
Priyanshu Dhar — Team Co Lead
Structured entity graph + deterministic resolver
What happens at this stage
Resolves the group tree, pins the last audited net worth to a date, and locks the entity's identity to the filing before a single number is computed. Enters: Entity selection from the NSE-500, BSE-500 or unlisted-500 universe; CIN, LEI and audited net worth. Leaves: A sealed entity header — identity, universe, group members, net worth as-of date.
Elapsed 8s of 78.6s on the rail · stage cost 8s
Layer 01 of 07 — Establish who is remitting, under which universe, and with what net worth. It cannot begin until layer zero (the treasury intake) has sealed its output.
Enters the layer
Entity selection from the NSE-500, BSE-500 or unlisted-500 universe; CIN, LEI and audited net worth.
What the layer does
Resolves the group tree, pins the last audited net worth to a date, and locks the entity's identity to the filing before a single number is computed.
Leaves the layer
A sealed entity header — identity, universe, group members, net worth as-of date.
Technology chosen
Structured entity graph + deterministic resolver
Identity is the one thing that must never be inferred by a model. A graph lookup either resolves or refuses; it cannot hallucinate a subsidiary.
Ownership
Priyanshu Dhar — Team Co Lead
Accountable for the design of this layer and the defensibility of its output.
Failure position
Unresolved identity halts the filing; nothing downstream can start.

In plain words
The system first works out exactly which company is sending money, who its parents and subsidiaries are, and how much the company is worth on paper.
Received from
Chain origin — the treasury's own intake starts the record.
Sealed and passed to
Which consumes: Sealed entity header, existing overseas commitments, guarantees and prior ODI/OPI drawdowns.

Read the second column downward: the model appears once. Every layer that decides a ceiling, a route or a prohibition is fully deterministic. That single property is what makes the rail presentable to a supervisor.
Time ledger
Automated rail
9 min
Seven layers running in sequence, each sealing a proved artefact, with all six authorities and the AD bank reading the same record as it forms.
Manual practice
28 days
The same file rebuilt five times by counsel, the treasury, the AD desk and two regulators — sequentially, each waiting on the last.
