## NIP-90 Provider Loop

## Provider lane (retired market loop)

GO ONLINE for the NIP-90 provider lane is persisted through the provider

command:

The NIP-90 and NIP-LBR provider loop was deleted on 2026-07-14 by commit

`21e82ce829` (`feat(vp1): retire money sites and wallet authority`). `pylon

provider once`, `pylon provider approve-labor`, `pnpm run provider:serve`,

`pnpm run smoke:nip90-provider`, and the `pylon wallet` family no longer exist.

The provider command offers exactly two subcommands:

```sh

pylon provider go-online

pylon provider approve-labor --approved-by-ref operator.public.<ref> --job-type code_task

pylon provider once

pylon provider go-offline

pnpm run smoke:nip90-provider

```

`go-online` marks the local runtime online, adds

`capability.public.pylon.nip90.text_inference.v0.3` and

`capability.public.pylon.labor.local_agent.v0.3`, and records the relay and

admission policy that the OpenTUI background loop will use. Labor jobs require

an explicit first-run operator approval record from `provider approve-labor`

before they execute on a machine. `provider once` is the headless smoke path

for one relay loop iteration. The default dashboard starts the same loop

automatically only when the persisted lifecycle is `online` or

`assignment-ready`. Own-capacity dispatch includes local active

`assignment run-no-spend` runners in `load.coding.<service>.busy`, so a

machine with two active Codex assignments reports those slots as busy instead

of advertising them as still available.

The provider loop subscribes to the scoped OpenAgents market relay by default,

publishes NIP-89 handler info, admits public kind `5050` text-inference

requests and OpenAgents labor kinds `5934` code task, `5935` review, and

`5936` document work, then publishes NIP-90 `7000` feedback plus result kinds

`6050` or `6934`-`6936`. Text inference executes the local Apple FM runtime.

Labor jobs execute through the contributor's configured local agent path

(`codex`, `opencode`, or `claude`) inside a bounded workspace and return

public-safe artifact refs. It uses the shared `@openagentsinc/nip90` package,

which re-exports the local `nostr-effect` protocol helpers.

Environment controls:

- `PYLON_NIP90_RELAYS`: comma-separated relay URLs. Defaults to

  the configured public Nostr relay (default `wss://nos.lol`).

- `PYLON_NIP90_PRICE_MSATS`: price floor and requested invoice amount.

  defaults to `1000`.

- `PYLON_NIP90_REQUEST_TTL_SECONDS`: request age limit. Defaults to one year.

- `PYLON_NIP90_MAX_INFLIGHT`: total local inflight admission leases. Defaults

  to `1`.

- `PYLON_NIP90_PER_BUYER_MAX_INFLIGHT`: per-buyer inflight leases. Defaults

  to `1`.

- `PYLON_LABOR_AGENT`: optional local labor agent selector: `codex`,

  `opencode`, or `claude_code`. If unset, Pylon detects `codex`, then

  `opencode`, then `claude`.

- `PYLON_LABOR_AGENT_COMMAND`: optional explicit local command prefix for

  advanced operators. Pylon appends the generated public-safe labor prompt.

Wallet boundary: the loop may put a raw BOLT 11 invoice into Nostr relay

events because NIP-90 payment-required/result tags require it, but local state,

ledger records, OpenAgents API payloads, logs, and issue evidence must only

carry public-safe receipt refs, amounts, event ids, and readiness refs. See

`docs/nip90-provider-loop.md`.

Legacy Spark/Breez migration boundary: `pylon wallet migrate-spark` is a

preflight-first compatibility path for old v0.2.x balances. It reports missing

Breez/Spark credential material as an actionable blocker and only proceeds with

explicit local consent. `pylon wallet send --rail spark --confirm-send` is the

direct Spark spend/withdraw path for credited Spark wallet funds. It is separate

from accepted-work payout authority and emits public-safe refs only. Users must

never paste a 12-word mnemonic, raw invoice, Lightning Address, API key, or Spark

storage path into GitHub, support threads, logs, or issue comments. See

`docs/legacy-spark-wallet-migration.md`.

Labor boundary: Pylon rejects labor requests that carry provider-auth-shaped

material, requests outside the bounded workspace, or a policy ref other than

`provider.compliant_usage_labor.v1`. The contributor's own local provider

accounts or API budgets stay on the contributor machine. OpenAgents pays for

accepted work output only and never resells, proxies, brokers, or transfers

provider credentials, sessions, account access, or consumer subscription

capacity.

`go-online` is local bookkeeping: it marks the runtime lifecycle online, probes

Claude, Codex, and Apple Foundation Models readiness, records the resulting

capability and blocker refs, and reports per-account coding capacity as

quantities. Own-capacity dispatch counts local active `assignment

run-no-spend` runners as busy, so a machine with two live Codex assignments

reports those slots as busy rather than available. The command opens no socket,

publishes no Nostr event, quotes no job, and earns nothing. `go-offline`

reverses the lifecycle.

The protocol package `packages/nip90` survived and grew, and the earning half

was revived offline as `openagents provider settle`, which decides what a

verified job earned against an NIP-LBR closeout receipt and pays nothing

(`payout_rail: "not_connected"`, `custody: "none"`). Reviving the rest needs an

owner-approved design and invariant change; `scripts/vp1-retired-money-surface-guard.mjs`

enforces that meanwhile.

For the full record of what was removed, what survived, and what a revival

needs, see `docs/nip90-provider-loop.md`, `docs/labor-market-provider-loop.md`,

and issue [#30](https://openagents.com/OpenAgentsInc/openagents/issues/30).

## Runtime

The runtime includes:

# Labor Market Provider Loop

Issue #4730 (epic #4726). Promise `labor.nostr_negotiation_market.v1`

(registry `2026-06-10.25`). Protocol: `docs/nips/LBR.md` (workspace

root). Roadmap: `docs/labor/2026-06-10-open-agent-labor-market-roadmap.md`.

The Pylon's NIP-LBR negotiation lane: watch agentic-coding jobs

(kind 5934) on the owned relay, quote the ones this device is

capability-true for, execute on acceptance through the labor runtime on

the contributor's **own** agent, deliver output-only results

(kind 6934).

## Negotiation discipline

LBR requests are **never auto-executed**. The lane routes ahead of the

generic provider flow in `runProviderJobOnce`:

1. **Quote.** A kind-5934 request is evaluated by

   `evaluateLbrRequestForQuote`: opt-in check, job-kind allowlist,

   quote-once, capability truth (`requiredCapabilityRefs` must all be

   declared by this Pylon's runtime state), concurrency bound, and the

   contributor's price must fit the request's bid. A passing request

   gets one kind-7000 quote with the amount and refs. Everything else

   gets a typed refusal and no relay traffic.

2. **Win.** A kind-7000 LBR acceptance addressed to this provider

   (carrying the requester's escrow receipt ref) triggers execution of

   the previously quoted job — acceptance without a quote is refused.

   acceptance addressed elsewhere is ignored.

3. **Execute.** Admission still applies: labor first-run operator

   approval (`pylon provider approve-labor`) is required before any

   machine runs its first market job. The workspace is bounded under

   the Pylon cache. The `claude_code` lane runs through the Claude

   Agent SDK runtime (`makeClaudeAgentLaborRuntime`): bounded sandboxed

   session, workspace-escape denial, settings isolation, turn and

   wall-clock budgets — not a CLI shell-out. Other agent kinds use the

   configured labor runtime.

4. **Verify, then deliver.** The request's `verificationCommandRef`

   maps through the bounded command registry

   (`LABOR_MARKET_VERIFICATION_COMMANDS`). Unknown refs are refused.

   The command must pass in the workspace or **no result is published**

   (`refusal.labor_market.verification_failed`) — the provider never

   ships failing work. A passing job publishes the kind-6934 result

   with output-only refs and a platform closeout ref.

## Configuration (contributor-owned, opt-in)

`laborMarket` section in the Pylon config file, or env overrides:

```json

{

  "laborMarket": {

    "autoQuote": true,

    "priceMsats": 1500000,

    "maxConcurrentJobs": 1,

    "agentKind": "claude_code"

  }

}

```

- `autoQuote` defaults to **false** — quoting is opt-in

  (`PYLON_LABOR_MARKET_AUTO_QUOTE=1` to enable by env).

- `priceMsats` is the contributor's price (`PYLON_LABOR_MARKET_PRICE_MSATS`).

  the platform sets no prices.

- The local state lives in `labor-market-state.json` (quote records,

  public-safe asserted on every write).

## Boundaries

The provider never self-accepts and never sees requester funds — it

sees an escrow receipt ref. Work runs on the contributor's own agent,

own credentials, own machine. Zero provider-auth material in events,

artifacts, or state (structurally scanned). The relay is transport, not

authority. Settlement truth comes from the platform's escrow/receipt

systems (#4729, #4732). Raw session material, diffs, and logs stay

on-device. Only refs travel.

# Labor market provider loop

Status: **retired**. The Pylon-side NIP-LBR negotiation lane this page used to

describe was deleted on 2026-07-14 by commit `21e82ce829` (`feat(vp1): retire

money sites and wallet authority`), along with `apps/pylon/src/labor-market.ts`.

No Pylon quotes, wins, or delivers market jobs today.

The protocol it spoke survives, and so does most of the discipline. This page

records what is still real, so the next reader of

[#30](https://openagents.com/OpenAgentsInc/openagents/issues/30) starts from the

tree rather than from a description of it.

Protocol: `docs/nips/LBR.md`. Related: `nip90-provider-loop.md`.

## Commands that no longer exist

| Removed command                | Status                                                                             |

| ------------------------------ | ---------------------------------------------------------------------------------- |

| `pylon provider approve-labor` | Deleted. `apps/pylon/src/cli-catalog.ts` offers only `go-online` and `go-offline`. |

| `pylon provider once`          | Deleted with the provider loop.                                                    |

| `pnpm run provider:serve`      | Deleted with `apps/pylon/scripts/nip90-provider-serve.ts`.                         |

The `laborMarket` configuration block, the `PYLON_LABOR_MARKET_AUTO_QUOTE` and

`PYLON_LABOR_MARKET_PRICE_MSATS` environment overrides, and the

`labor-market-state.json` quote store went with the module that read them.

`evaluateLbrRequestForQuote` and the `LABOR_MARKET_VERIFICATION_COMMANDS`

registry no longer exist anywhere in the tree.

## What survived

**The protocol, in `packages/nip90`.** Kept and extended through the

retirement:

- `lbr.ts` — request, quote, acceptance, and result.

- `lbr-closeout.ts` — a content-addressed, public-safe receipt binding one whole

  lifecycle, carrying `verificationCommandRef`, `testRef`,

  `platformCloseoutRef`, and a re-derivable digest.

- `lbr-bond.ts` — forfeitable provider bonds, added after the retirement in

  `3590489b6e`.

**The buyer half of negotiation.** `packages/sarah/src/lbr-request-quote/` was

recovered on 2026-07-24 as request and quote only. It does not accept, execute,

or settle.

**The admission rules, uncalled.** `apps/pylon/src/labor.ts` still holds the

parts of the lane that were about safety rather than money: the first-run

operator approval store, the bounded workspace resolver that rejects `..` and

`.git` escapes, `evaluateLaborRequestSafety` and its provider-auth

exfiltration detector, the public-safe result projection, and the sandboxed

local agent command builders for `codex`, `opencode`, and `claude_code`.

Nothing imports the module; `makeConfiguredLaborRuntime` sits in

`scripts/uncalled-production-symbol-baseline.json`.

**The wrong half of the state machine.**

`apps/pylon/src/coordinator/labor-job-state.ts` also survives, also uncalled.

Read it before reusing it. Its transition table contains

`settle: { delivered: "settled" }`, and `delivered` is a state the provider

sets, so that machine pays a provider's own claim. The doctrine the Pylon arc

earned is the opposite: a lease is not an earning claim, and only a settlement

receipt is. That rule is not expressible in this table.

## What replaced the settlement end

`openagents provider settle` (commit `f0c36de6a0`) settles against the

surviving LBR closeout receipt rather than against a provider's submission. An

earning requires a receipt that names this job and this provider, was not

issued by the provider to itself, carries a verification command _and_ the

evidence it produced, carries the platform's own closeout, is

content-addressable, landed inside the lease window, and prices the job exactly

as the lease did. Ten named refusals cover the failures, and each earns zero.

Nothing moves: a settled decision reports `payout_rail: "not_connected"` and

`custody: "none"`.

## The boundaries, which still hold

These were never the part that broke, and they constrain any revival:

- Pay for verified work only, never for presence.

- The provider never self-accepts and never sees requester funds — it sees a

  receipt ref.

- Work runs on the contributor's own agent, own credentials, own machine. No

  provider-auth material enters events, artifacts, or state.

- The relay is transport, not authority. Settlement truth comes from the

  platform's receipt systems.

- Raw session material, diffs, and logs stay on-device. Only refs travel.

## What a revival still needs

`INVARIANTS.md` holds that payments, markets, wallet custody, payout, billing

credits, and settlement are outside the accepted MVP, and that any revival

needs a fresh owner-approved design, custody model, invariant change, and proof

program. `scripts/vp1-retired-money-surface-guard.mjs` enforces that on every

push.

Beyond the owner decision, #30 still lists: presence with capacity as a

quantity, the claim and lease transport with its idle keepalive and resubscribe

(the 2026-06-12 run went dark about a minute after going online because 60

seconds of relay silence was treated as fatal), a provider identity seam, and a

buyer. Per the issue, the first buyer is OpenAgents' own operation — validator

replay jobs, delegation children, and registry service jobs. None of that demand

exists as jobs yet.

# NIP-90 Provider Loop

# NIP-90 provider loop

Status: implemented for `0.3.0-rc1` as the local GO ONLINE provider lane.

Status: **retired**. The loop this page used to describe was deleted on

2026-07-14 by commit `21e82ce829` (`feat(vp1): retire money sites and wallet

authority`). Nothing in the tree serves NIP-90 jobs today.

The provider lane restores the March NIP-90 behavior behind the current Pylon

OpenTUI state model. It uses the shared `@openagentsinc/nip90` package, backed by

the workspace `nostr-effect` protocol helpers, instead of rebuilding NIP-90

parsing or event construction locally.

This page is kept because the code it describes is the port source for

[#30](https://openagents.com/OpenAgentsInc/openagents/issues/30), the issue that

tracks reviving provider mode. It records what was removed, what survived, and

what `pylon provider` actually does now, so nobody spends an afternoon looking

for a command that no longer exists.

## Commands

## Commands that no longer exist

```sh

pylon provider go-online

pylon provider once

pylon provider go-offline

pnpm run smoke:nip90-provider

pnpm run provider:serve

```

`go-online` persists lifecycle `online` and adds

`capability.public.pylon.nip90.text_inference.v0.3` to the local runtime

state. The default dashboard starts the provider loop only when the persisted

runtime lifecycle is `online` or `assignment-ready`.

Earlier revisions of this page told you to run these. Do not:

`provider once` is the headless smoke entrypoint. It publishes NIP-89 handler

info and subscribes once to the configured relays. If the persisted lifecycle is

offline, it exits with a public-safe `provider_not_online` reason.

| Removed command                 | Status                                                     |

| ------------------------------- | ---------------------------------------------------------- |

| `pylon provider once`           | Deleted. The CLI catalog offers no `once` subcommand.      |

| `pnpm run provider:serve`       | Deleted with `apps/pylon/scripts/nip90-provider-serve.ts`. |

| `pnpm run smoke:nip90-provider` | Deleted. No such script is defined.                        |

| `pylon provider approve-labor`  | Deleted. See `labor-market-provider-loop.md`.              |

`pnpm run provider:serve` (`scripts/nip90-provider-serve.ts`) is the

long-running headless serve entrypoint: it runs the persistent loop against

the configured relays with the real Pylon home, the default local Apple FM

runtime, and the MDK agent wallet for payment-required quotes

(`PYLON_MDK_WALLET_HOME` points the wallet subprocess at a wallet home that

can actually create invoices). It only ever issues receive invoices. It

never pays.

The files behind them went in the same commit: `apps/pylon/src/provider-nip90.ts`,

`apps/pylon/src/labor-market.ts`, `apps/pylon/src/multi-earning-ledger.ts`, the

Spark wallet stack, and the MDK treasury and tips services.

`pnpm run smoke:nip90-provider` uses a temporary Pylon home and the scoped market

relay to prove subscribe, NIP-89 advertise, targeted kind `5050` intake, local

runtime execution, kind `7000` feedback, kind `6050` result publication, and

redacted local earnings state. It uses fake local runtime/wallet adapters and

does not claim paid settlement.

## What `pylon provider` does today

## Relay And Runtime

`apps/pylon/src/cli-catalog.ts` declares exactly two subcommands:

Default relay:

```text

wss://relay.openagents.com

```sh

pylon provider go-online

pylon provider go-offline

```

The loop:

- publishes NIP-89 handler info for kind `5050`.

- stays subscribed through quiet periods: an idle relay (no frames for the

  60s message window) is treated as keep-waiting, not an error, and any

  dropped socket or transient relay/runtime failure logs and resubscribes

  after a short delay instead of stopping the service (#4866 root-cause fix

  for `[NIP-90] Service stopped with error: ... relay message timed out`).

- subscribes to targeted and broad kind `5050` text-inference requests.

- rejects malformed, encrypted, wrong-target, stale, missing-bid, underbid,

  duplicate, and over-capacity requests before local execution.

- executes admitted jobs on the local Apple FM runtime through a

  runtime-neutral `ProviderTextRuntime` contract.

- publishes NIP-90 kind `7000` states: `payment-required`, `processing`,

  `success`, and `error`.

- publishes kind `6050` results with `amount` and BOLT 11 data for NIP-90

  settlement.

- records local earnings as public-safe refs and amounts.

## Wallet Boundary

The raw BOLT 11 invoice is allowed only inside Nostr relay events required by

NIP-90. Pylon must not write raw invoices, mnemonics, preimages, payment

hashes, wallet-home paths, or agent tokens into OpenAgents API payloads, logs,

local persisted provider state, issue comments, or commits.

Persisted earnings include:

- request event id.

- requester pubkey.

- amount in msats/sats.

- public-safe receipt ref.

- result event id.

- timestamp.

They do not include raw invoice or wallet material.

## Current Evidence Limit

Unit coverage verifies admission, event construction, and the redaction

boundary. A funded buyer end-to-end payment is intentionally left for the

buy-mode/funded smoke issues because it moves live sats and requires operator

approval.

`go-online` is local bookkeeping. It writes runtime lifecycle `online`, probes

the Claude, Codex, and Apple Foundation Models readiness this device actually

has, records the resulting capability and blocker refs, and reports per-account

coding capacity as quantities — available, busy, queued, and ready slots per

connected Codex account. It opens no socket, publishes no Nostr event, quotes

no job, and earns nothing. `go-offline` reverses the lifecycle.

Whatever runs on that capacity arrives through the assignment and dispatch

paths, not through a market.

## What survived the removal

- **The protocol package.** `packages/nip90` was kept and extended through the

  retirement. It carries the NIP-LBR lane — `lbr.ts` (request, quote,

  acceptance, result), `lbr-closeout.ts` (a content-addressed, public-safe

  receipt binding one whole lifecycle), and `lbr-bond.ts`, a post-retirement

  addition covering forfeitable provider bonds.

- **The presence lane refs.** `packages/pylon-core/src/presence/nip90-lane-refs.ts`

  still resolves relay URLs from `PYLON_NIP90_RELAYS` and builds the

  `lane.public.nip90.*` refs that `presence.ts` would attach to a registration.

  In practice it never fires: `providerDiscoveryFields` only attaches those

  fields to a Pylon whose capability refs include

  `PYLON_NIP90_PROVIDER_CAPABILITY_REF`, and no code path adds that ref any

  more.

- **The labor admission rules.** `apps/pylon/src/labor.ts` still holds workspace

  bounding, provider-auth exfiltration detection, the public-safe result

  projection, and the local agent command builders. Nothing imports it;

  `makeConfiguredLaborRuntime` is listed in

  `scripts/uncalled-production-symbol-baseline.json`.

- **The buyer half of the negotiation.** `packages/sarah/src/lbr-request-quote/`

  was recovered on 2026-07-24 as request and quote only.

## What was revived, and how far

`openagents provider settle` (`packages/openagents-cli/src/provider-command.ts`

and `provider-settlement.ts`, commit `f0c36de6a0`) revives the earning half at

the one seam that can be proven offline. It reads a lease and an LBR closeout

receipt from files and decides what the job earned.

An earning requires a receipt that names this job and this provider, was not

issued by the provider to itself, carries both a verification command and the

evidence that command produced, carries the platform's own closeout, is

content-addressable, landed inside the lease window, and prices the job exactly

as the lease did. Ten named refusals cover the ways that fails, and each earns

zero.

Nothing moves. A settled decision reports `payout_rail: "not_connected"` and

`custody: "none"`. There is no key, no wallet daemon, and no spend authority.

## Why the rest stays unbuilt

`INVARIANTS.md` still says that payments, markets, wallet custody, payout,

billing credits, and settlement are not part of the accepted MVP, and that any

revival requires a fresh owner-approved design, custody model, invariant change,

and proof program. `scripts/vp1-retired-money-surface-guard.mjs` enforces it on

every push.

Presence with capacity-as-quantity and the claim, lease, and submit transport

also need a market transport the do-not-build register defers. When that lane

arrives it takes the relay, provider-daemon, and skeptical-client shape, not a

NIP-90 or DVM revival.

One failure from the original loop is worth carrying forward into any

replacement. The live run on 2026-06-12 treated 60 seconds of relay silence as

fatal, so every registered provider went dark about a minute after going online.

A responder needs idle keepalive and resubscribe, and an idle relay has to be

read as keep-waiting rather than as an error.

 * `presence.ts`'s heartbeat needs exactly these four symbols to publish

 * provider-discovery fields (`PYLON_NIP90_PROVIDER_CAPABILITY_REF`,

 * `providerNip90LaneRefs`, `relaysFromEnv`) and their supporting constant

 * (`OPENAGENTS_MARKET_RELAY_URL`). The rest of `provider-nip90.ts` — job

 * request/result handling, the labor-market bridge, and the Apple FM client

 * used to *serve* NIP-90 work — depends on `wallet.ts`, `labor-market.ts`,

 * and `@openagentsinc/pylon-runtime` and stays in `apps/pylon`. This module

 * depends only on the public `@openagentsinc/nip90` job-kind constants, so

 * it is a clean leaf for presence to sit on top of. `apps/pylon`'s

 * `provider-nip90.ts` re-exports these symbols (rather than redefining them)

 * so there is a single source of truth.

 * (`OPENAGENTS_MARKET_RELAY_URL`). This module depends only on the public

 * `@openagentsinc/nip90` job-kind constants, so it is a clean leaf for

 * presence to sit on top of.

 *

 * The serving half is gone. `apps/pylon/src/provider-nip90.ts`, which used

 * to re-export these symbols and handle job requests and results, was

 * deleted on 2026-07-14 by `21e82ce829` ("retire money sites and wallet

 * authority"), so this file is now the only definition. Nothing adds

 * `PYLON_NIP90_PROVIDER_CAPABILITY_REF` to a runtime's capability refs any

 * more, which means `providerDiscoveryFields` returns nothing in practice.

 * These refs are kept as the port source for issue #30. See

 * `apps/pylon/docs/nip90-provider-loop.md`.
