Supersedes #322 — @twzrd-sol's seven commits, unchanged and rebased onto main, plus one review-fix commit. Opened here because #322's head is on a fork and a rebase needs a force push GitHub will not let a maintainer make.

Addresses #304. Replaces the local liveSpendControl answer from #303 with the general one.

The proxy, the Polymarket tool and doctor each built their own SpendControl, so amount windows were enforced per surface and saveHistory() was last-writer-wins on disk. getSharedSpendControl() is now the single default; injection is unchanged everywhere.

Review fixes on top

The session window still resets on an in-process proxy restart. sessionSpent/sessionCalls are instance state that is never persisted, so the reset used to happen by accident: every startProxy() built its own SpendControl. One ledger for the whole process quietly redefined session as "since the gateway booted", and left it asymmetric — a gateway restart still reset it, an in-process restart no longer did. docs/configuration.md:669 and the /policy help both state "session resets on restart", and supersedeEmptyConfigStartup puts ordinary boots through two starts, so this was not a corner case. The restart path now calls the already-existing resetSession() on purpose. History and the rolling hourly/daily windows still survive, which is the point of sharing the ledger.

The regression test pins the wiring rather than the method: it asserts the same instance reaches both startProxy calls, then that session is back to 0 while daily still counts the payment recorded before the restart. Removing the reset call turns it red (expected 3 to be +0).

buildPolymarketTool() takes no deps at the registration site. It was passed getSharedSpendControl(), which is exactly what resolveSpendControl already falls back to — so the argument bought nothing and cost a synchronous read of spending.json on every plugin registration, including the installs that never place a bet and nine register() call sites in the lifecycle tests that would reach the developer's real home directory.

Guarded the conflict-recovery re-read in save(). load() now throws UnreadableSpendPolicyError where it returned null. A file that goes unreadable between the conflict check inside saveLimits and the re-read at src/spend-control.ts would have cleared the limits and surfaced the wrong error class to /policy, which branches on SpendPolicyConflictError.

Verification

  • npm run typecheck, npm run lint: clean
  • npm test: 982 passed, 1 skipped, 0 failed
  • npm run build + dist smoke: pass
  • npm run test:e2e: 20 passed, 1 skipped, 0 failed
  • npm run test:e2e:tool-ids: proxy boots, binds, closes clean

Cross-process writes are still a known limit, unchanged from #322: a CLI write while the gateway runs is a whole-object replace from another process. Not a file watcher, not a cross-process lock.

Summary by CodeRabbit

  • Improvements

    • Spend policies are now consistently shared across proxy requests, doctor checks, and Polymarket transactions.
    • Restarting the proxy refreshes policy limits while preserving daily spending history and resetting the session window.
    • Policy changes remain enforced across all supported spending surfaces.
  • Bug Fixes

    • Improved handling of unreadable or malformed spending-policy files, preventing accidental limit expansion and clearly reporting policy errors.

…et, doctor

Per-surface SpendControl instances each loaded spending.json at construction
and then enforced hourly/daily/session windows against diverging in-memory
history — every aggregate window effectively doubled — while each instance's
save() last-writer-won the file's history, dropping the other surface's
records on restart.

getSharedSpendControl() is now the single process-wide instance. startProxy,
createDoctorX402Client, and the polymarket resolvers all default to it, and
index.ts threads it explicitly through the startProxy options and the
buildPolymarketTool deps seam. Injectable deps are unchanged for tests.

New tests: LLM spend recorded through the wired instance blocks a Polymarket
order placed via tool.execute with no per-call deps; tool functions called
with no deps resolve the shared instance, not a private one; a restart over
the same storage sees both surfaces' records instead of only the last
writer's.

…surface proven on the singleton

Restart semantics for the process-wide SpendControl, stated rather than
implied: an in-process proxy restart keeps history and rolling windows but
re-reads limits from spending.json, so a hand-edit made while the proxy was
up still applies — which is what a restart did when each surface built its
own instance. SpendControl.reloadLimits() does the limits-only re-read and
fails closed exactly like the constructor: a malformed file refuses every
payment until repaired, and a repaired file clears the refusal.

Tests pin the other two guarantees the singleton exists for: a /policy write
on it is enforced by a Polymarket order placed with no injected deps, and
Polymarket spend recorded on it refuses a proxy x402 payment over the hourly
cap — the cross-surface direction the earlier test did not cover. Both test
files now leave a fresh in-memory instance behind after each test so the
singleton cannot leak between them.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
reloadLimits() adopted the on-disk limits but left diskLimits — the value a
later saveLimits() compares storage against — at whatever the instance had
last read or written. The first write after an in-process restart that had
picked up an external edit was therefore refused as a conflict with the very
state it had just reloaded. The baseline now follows what was just read.
Test goes red with the one line removed.

…t may pay

CodeRabbit caught a fail-open this PR introduced. `reloadLimits()` is new
here, so the bug is new here too.

`FileSpendControlStorage.load()` has two failure modes. A malformed policy
list throws `MalformedSpendPolicyError`, which the reload already handled
by refusing every payment. A torn or unreadable file took the other path:
it logged and returned `null`, which is indistinguishable from "no file
yet". The reload then cleared `policyFileBroken` and set `limits = {}`, so
a `spending.json` truncated by a crash plus one in-process proxy restart
left the proxy running with no caps and no allow/deny lists.

The constructor can treat an unreadable file as an empty start because it
has nothing to lose. A reload does. Guessing at the call site is not
possible while both cases return `null`, so the distinction now lives at
the storage boundary: `load()` throws `UnreadableSpendPolicyError` for a
read or parse failure, and `null` again means only "nothing stored".

- constructor: catches it, logs the same "starting fresh" warning, and
  begins with no limits. Startup behaviour is unchanged.
- reload: catches it, logs, and returns without touching limits or any
  refusal state. The last known-good policy stays in force.

Refusing outright on a torn file would be stricter, but that is a change
to startup semantics beyond this PR; not widening is the part that
belongs here.

Test added red first: set a daily cap, make `load()` fail, reload, and
assert the over-cap payment is still refused. Before the fix the reload
reset limits to `{}` and it was allowed. 942 tests, typecheck, lint and
prettier clean.

…e variable

Second CodeRabbit finding on this PR, and a fair one: the accessor promised
a process-wide ledger while holding it in a module variable, so the claim
only held for a single module instance.

That is not a safe assumption in this plugin. A global install
(~/.openclaw/extensions/clawrouter) and an npm-projects install
(~/.openclaw/npm/projects/blockrun-clawrouter-*) can both be resolved in
one gateway, and two module copies would each hold their own ledger --
every window enforced once per copy, which is the per-surface split this
singleton exists to end.

index.ts already defends against exactly this for startup state
(`__clawrouterProxyStarted`, `__clawrouterStartupGeneration` and the rest
live on `process`). The ledger now follows the same convention under
`__clawrouterSharedSpendControl`, so `getSharedSpendControl()` and
`setSharedSpendControl()` resolve through one process slot.

The test pins where the instance lives rather than simulating a dual load;
loading two isolated copies of the module under vitest would test the
loader more than the ledger.

943 tests, typecheck, lint and prettier clean.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The unit tests for the torn-file path use an in-memory stub that throws
UnreadableSpendPolicyError on demand. That proves the branch is handled; it
does not prove a genuinely truncated file on disk reaches it, and "the file
is not what the parser expected" is precisely the thing a stub cannot
reproduce. These drive the real FileSpendControlStorage against a real
half-written file, with a temp HOME set before import so WALLET_DIR lands
in the sandbox.

Three of the four go red against the pre-fix code, and one of them
documents a defect worse than the one this PR set out to fix:

- reload: the daily cap survives the torn read (the fail-open this PR fixes)
- history save: the damaged file is left byte-identical, where before it was
  rewritten from limits that had just failed to load
- policy write: `policy limit daily 2` now reports isError and leaves the
  file alone. Before, `result.isError` was undefined -- the command reported
  SUCCESS and overwrote the damaged file, discarding whatever payee or asset
  lists sat in the unreadable part. An operator repairing a corrupted policy
  file was the most likely person to hit that.

The fourth pins startup behaviour as deliberately unchanged: a torn file
must not take the constructor down, and still begins with no limits.

947 tests, typecheck, lint and prettier clean.

…estart

The process-wide ledger fixed the per-surface split, but it also took over a
reset that used to happen by accident. `sessionSpent`/`sessionCalls` are
instance state that is never persisted, so every `startProxy()` building its
own SpendControl was what made `session` reset on a proxy restart —
docs/configuration.md and the /policy help both state that as the contract.
One ledger for the whole process quietly redefined `session` as "since the
gateway booted", and left it asymmetric: a gateway restart still reset it, an
in-process restart no longer did. `supersedeEmptyConfigStartup` puts ordinary
boots through two starts, so this was not a corner case.

The restart path now resets it on purpose. History and the rolling hourly and
daily windows still survive, which is the point of sharing the ledger.

The regression test pins the wiring rather than the method: it asserts the same
instance reaches both `startProxy` calls, then that `session` is back to 0
while `daily` still counts the payment recorded before the restart. Removing
the reset call turns it red.

Also:
- `buildPolymarketTool()` takes no deps at the registration site. It was passed
  `getSharedSpendControl()`, which is what `resolveSpendControl` already falls
  back to, so the argument bought nothing and cost a synchronous read of
  spending.json on every plugin registration — including the installs that
  never place a bet, and nine `register()` call sites in the lifecycle tests
  that would reach the developer's real home directory.
- Guard the conflict-recovery re-read in `save()`. `load()` now throws where it
  returned null, so a file that goes unreadable between the conflict check and
  the re-read would clear the limits and surface the wrong error class to
  /policy, which branches on `SpendPolicyConflictError`.

📝 Walkthrough

Walkthrough

The PR introduces a process-wide spend-control ledger, reloads policy limits during proxy restarts, preserves daily history, resets session history, and shares enforcement across proxy, doctor, policy commands, and Polymarket operations. It also adds unreadable-policy handling and integration tests.

Changes

Shared spend-policy lifecycle

Layer / File(s) Summary
Spend-control lifecycle and shared instance
src/spend-control.ts, src/spend-control.test.ts, src/spend-control.torn-file.test.ts
SpendControl now supports limit reloads, shared process-wide access, and separate handling for unreadable and malformed policy files. Tests cover reloads, history preservation, torn files, conflict recovery, and policy errors.
Runtime shared-ledger wiring
src/index.ts, src/proxy.ts, src/doctor.ts, src/index.lifecycle.test.ts
Proxy startup, doctor x402 calls, and policy commands resolve the shared ledger. Restarts reload limits, reset session spending, and preserve daily spending.
Polymarket spend-policy integration
src/polymarket/spend-policy.ts, src/polymarket/tool.ts, src/polymarket/spend-policy.test.ts
Polymarket signing paths accept optional spend dependencies and otherwise resolve the shared ledger. Tests verify cross-surface enforcement for orders and x402 payments.

Merge Risk: 🟠 High · up to a34c4

Unreadable or structurally invalid policy files can cause configured spending limits to stop being enforced, risking excess payments. The machine-local dependency symlink can also break other checkouts. These issues should be fixed before merge.

The target is an absolute path under one developer's home directory. Other checkouts will have a dangling link, and dependency resolution can fail before tests or builds run. Remove this entry and recreate dependencies from the repository's package manifest and lockfile.

Reject invalid policy document shapes before replacing live limits.

load() accepts valid JSON such as [] or {"limits":[]} as an empty policy. Line 499 then clears active limits, so an over-cap payment can pass after reloadLimits(). Validate the root object and limits object, and raise MalformedSpendPolicyError when either is invalid.

If spending.json previously contained a cap but becomes unreadable, this branch leaves limits empty and does not set policyFileBroken. A new proxy process can then authorize payments that exceeded the prior cap.

`3f99536` (#331) committed `node_modules` as a **symlink to an absolute path
on one developer's machine**. Anyone who pulled main got that link in their
working tree, where it shadows their real install and breaks `npm ci`, `tsup`
and every `.bin/*` resolution with "too many levels of symbolic links".

It got in because `.gitignore` said `node_modules/` — with a trailing slash,
which matches a directory and only a directory. The scratch worktrees used to
rebase that PR pointed at the real install with `ln -s`, and a symlink named
`node_modules` is not a directory, so it sailed past the ignore rule and into
`git add -A`.

Removes it from the index and lists both forms in `.gitignore`, so the
symlink shape cannot come back the same way.
