From 9a8f68b54541ee1fdacfe3f229e7ca4eb6e0c509 Mon Sep 17 00:00:00 2001 From: nijoe1 Date: Wed, 5 Aug 2026 15:30:00 +0300 Subject: [PATCH 01/14] feat(wallet): resolve the signing key from an external secret manager Adds a third custody mode alongside a raw key and a Foundry keystore: the config holds a : pointer and the key is fetched into memory per command, so nothing is ever at rest. This is the same shape the keystore path already uses -- config names an external source, and a helper is run at use time to produce the key on stdout -- so it introduces no new concept, only a second instance of an existing one. It closes the gap keystore-setup.md documents: keystore mode prompts on a tty, so MCP and CI have had no custody option but a key in the config file. A key reference prompts for nothing, which makes it the first mode that works under automation with no key on disk. After wallet init --keyRef, every command is ordinary foc-cli usage -- no wrapper, no prefix, no environment to prepare. Design notes: Providers are a closed set. The executable is chosen by code and only the reference comes from config, so a tampered config cannot turn key resolution into arbitrary command execution -- the property the keystore path has, and the reason there is no general "run this to get my key" field. keyRef is absent on every existing install, so the branches below it are reached unchanged and there is nothing to migrate. Only one custody mode is ever live: setting any of them clears the others. Without that, a stale privateKey would sit at rest where nothing reads it. execFileSync does not apply PATHEXT on Windows, where an npm-installed helper is clawdi.cmd. Candidates are probed and stat'd rather than reaching for shell: true, which would put a config-supplied string through a shell. Errors never echo what was resolved: a reference pointing at the wrong field must not print that field's contents. Resolution stays lazy, so read-only commands never pay for it. wallet balance now reports keySource, so a vault-backed setup is verifiable at a glance -- the address proves which key signed, this proves where it came from. --- cli/src/client.ts | 22 +++ cli/src/commands/wallet/balance.ts | 9 + cli/src/commands/wallet/init.ts | 122 ++++++++++++- cli/src/config.ts | 15 ++ cli/src/key-ref.ts | 153 +++++++++++++++++ cli/tests/command-mocks.ts | 9 + cli/tests/key-ref.test.ts | 160 ++++++++++++++++++ skills/foc-cli/SKILL.md | 13 +- .../references/integrations/clawdi-vault.md | 67 ++++++++ skills/foc-cli/references/key-injection.md | 70 ++++++++ skills/foc-cli/references/keystore-setup.md | 5 +- 11 files changed, 635 insertions(+), 10 deletions(-) create mode 100644 cli/src/key-ref.ts create mode 100644 cli/tests/key-ref.test.ts create mode 100644 skills/foc-cli/references/integrations/clawdi-vault.md create mode 100644 skills/foc-cli/references/key-injection.md diff --git a/cli/src/client.ts b/cli/src/client.ts index f5df3c7..50b7d1e 100644 --- a/cli/src/client.ts +++ b/cli/src/client.ts @@ -4,9 +4,31 @@ import { getChain } from '@filoz/synapse-core/chains' import { createPublicClient, createWalletClient, type Hex, http } from 'viem' import { privateKeyToAccount } from 'viem/accounts' import config from './config.ts' +import { resolveKeyRef } from './key-ref.ts' import { expandHome } from './utils.ts' +/** + * Which custody mode is configured, without resolving anything.

Never suggest a tool the machine does not have. `wallet init` guidance offered `--keyRef clawdi:...` unconditionally, which on a machine without clawdi is a dead end an agent will walk into. Providers are now probed on PATH -- a stat, no process, no network -- and only offered where they would work. The reference docs still describe every provider; a call to action describes what you can do right now. Refuse to discard a configured key. An explicit method replaced whatever was configured, silently and unrecoverably. It now names what would be lost -- the derived address for a private key, the path for a keystore, the reference for a key reference, never the key itself -- and asks on a terminal, or fails with WALLET_ALREADY_CONFIGURED and a --force call to action in agent mode. Only a change that actually replaces something triggers it: re-running the same reference is idempotent, and prompting for that would train agents to pass --force reflexively, defeating the guard. Check the cheap things first. Every wallet-touching command now runs a preflight before constructing a client, so "no wallet" and "provider not installed" arrive as WALLET_NOT_CONFIGURED / KEY_REF_PROVIDER_MISSING with actionable next steps, instead of escaping as an untyped throw from inside key resolution. The preflight deliberately does not resolve the key: that needs an authenticated provider and a round trip, and belongs at use time. Configuring a reference before installing its provider stays legal -- image layers and provisioning scripts run in an order you do not control -- but `wallet init` now reports providerAvailable and warns, so the next command cannot fail confusingly. --- cli/src/client.ts | 67 +++++++++- cli/src/commands/dataset/create.ts | 7 +- cli/src/commands/dataset/details.ts | 7 +- cli/src/commands/dataset/list.ts | 7 +- cli/src/commands/dataset/terminate.ts | 7 +- cli/src/commands/download.ts | 6 + cli/src/commands/multi-upload.ts | 6 + cli/src/commands/piece/list.ts | 7 +- cli/src/commands/piece/remove.ts | 7 +- cli/src/commands/upload.ts | 6 + cli/src/commands/wallet/balance.ts | 7 +- cli/src/commands/wallet/costs.ts | 6 + cli/src/commands/wallet/deposit.ts | 6 + cli/src/commands/wallet/fund.ts | 6 + cli/src/commands/wallet/init.ts | 146 ++++++++++++++++++++- cli/src/commands/wallet/summary.ts | 7 +- cli/src/commands/wallet/withdraw.ts | 6 + cli/src/key-ref.ts | 20 +++ cli/tests/command-mocks.ts | 40 ++++-- cli/tests/synapse-commands.test.ts | 87 +++++++++++- skills/foc-cli/SKILL.md | 7 +- skills/foc-cli/references/key-injection.md | 14 ++ 22 files changed, 445 insertions(+), 34 deletions(-) diff --git a/cli/src/client.ts b/cli/src/client.ts index 50b7d1e..e82daa5 100644 --- a/cli/src/client.ts +++ b/cli/src/client.ts @@ -4,9 +4,74 @@ import { getChain } from '@filoz/synapse-core/chains' import { createPublicClient, createWalletClient, type Hex, http } from 'viem' import { privateKeyToAccount } from 'viem/accounts' import config from './config.ts' -import { resolveKeyRef } from './key-ref.ts' +import { + availableProviders, + isProviderAvailable, + parseKeyRef, + resolveKeyRef, +} from './key-ref.ts' import { expandHome } from './utils.ts' +type Problem = { code: string; message: string; cta?: any } + +/** + * Cheap checks that must pass before a command can sign anything. + * + * Run before constructing a client so an unusable setup fails as a typed, + * actionable error instead of escaping as an untyped throw from deep inside + * key resolution.

Any 32 bytes form a valid secp256k1 key, so the old unanchored first-match took the leading half of a longer blob and signed as a different address instead of failing. Run .cmd/.bat helpers through cmd.exe. npm installs clawdi.cmd on Windows, which CreateProcess cannot launch and Node has refused to since the fix for CVE-2024-27980: the PATH probe found it, the launch failed with EINVAL, and that was reported as "not logged in / wrong project". References and project scopes are restricted to characters a shell treats literally, so a tampered config still cannot become command execution.

It now also reports KEYSTORE_INTERACTIVE_ONLY under an agent and KEYSTORE_TOOL_MISSING when Foundry is unreachable, plus MALFORMED_KEY_REF for a reference with no provider prefix, which previously escaped as UNKNOWN with no code and no way to act on it. KEY_REF_PROVIDER_MISSING no longer suggests `wallet init --auto --force`. A missing provider is usually a short PATH under an agent, and agents follow calls to action: the only one offered would have replaced a funded vault-backed wallet with a throwaway testnet key. It now carries no command and is marked retryable. Collapse the fifteen pasted copies of the guard into requireWallet(), and assert structurally that every command building a signing client calls it first. --- cli/src/client.ts | 116 ++++++++++-- cli/src/commands/dataset/create.ts | 9 +- cli/src/commands/dataset/details.ts | 9 +- cli/src/commands/dataset/list.ts | 9 +- cli/src/commands/dataset/terminate.ts | 9 +- cli/src/commands/download.ts | 9 +- cli/src/commands/multi-upload.ts | 9 +- cli/src/commands/piece/list.ts | 9 +- cli/src/commands/piece/remove.ts | 9 +- cli/src/commands/upload.ts | 9 +- cli/src/commands/wallet/balance.ts | 13 +- cli/src/commands/wallet/costs.ts | 9 +- cli/src/commands/wallet/deposit.ts | 9 +- cli/src/commands/wallet/fund.ts | 9 +- cli/src/commands/wallet/summary.ts | 9 +- cli/src/commands/wallet/withdraw.ts | 9 +- cli/tests/command-mocks.ts | 25 ++- cli/tests/preflight.test.ts | 252 ++++++++++++++++++++++++++ 18 files changed, 423 insertions(+), 109 deletions(-) create mode 100644 cli/tests/preflight.test.ts diff --git a/cli/src/client.ts b/cli/src/client.ts index e82daa5..a460ec7 100644 --- a/cli/src/client.ts +++ b/cli/src/client.ts @@ -5,14 +5,22 @@ import { createPublicClient, createWalletClient, type Hex, http } from 'viem' import { privateKeyToAccount } from 'viem/accounts' import config from './config.ts' import { - availableProviders, + isOnPath, isProviderAvailable, + keyRefCtaCommands, parseKeyRef, + providerInstallHint, resolveKeyRef, } from './key-ref.ts' -import { expandHome } from './utils.ts' +import type { OutputContext } from './output.ts' +import { expandHome, isAgent } from './utils.ts' -type Problem = { code: string; message: string; cta?: any } +type Problem = { + code: string + message: string + cta?: any + retryable?: boolean +} /** * Cheap checks that must pass before a command can sign anything. @@ -21,12 +29,16 @@ type Problem = { code: string; message: string; cta?: any } * actionable error instead of escaping as an untyped throw from deep inside * key resolution.

The consequence stated is the one that actually applies: only a stored private key is destroyed by the swap, while a keystore file stays on disk and a vault key stays in the vault.

Previously the PATH probe found the helper, the preflight passed, and the launch failed with `EINVAL` — reported as "not logged in / key missing / wrong project", none of which was true.

Silent wrong-key hazards: - `wallet init --keyRef X` on a wallet already pinned to `--keyProject` dropped the pin. The force guard correctly reads an identical reference as a no-op and never asks, so the delete ran unconfirmed and the next command re-resolved against the provider's default project — a different key, a different signing address, nothing on screen. The scope is now cleared only when it stops applying: an explicit `--keyProject ""`, or a reference that actually changed. - A configured keystore was invisible to the already-configured checks, so bare `wallet init` fell past them to the interactive prompt, which writes a private key and deletes the keystore. `--force` bypassed entirely. It now reports `already_configured` like the other two modes. - The keystore key scrape kept an unbounded `search()` + `slice(+66)` while the key-reference path in the same branch refused exactly that shape. Every 32-byte value is a valid secp256k1 key, so the first 64 hex digits of a longer blob would have signed as a different address. Both paths now share `findPrivateKeys`, and the ambiguous case is refused rather than guessed. - `--keyRef 0x<64 hex>` — plausible, since it sits beside `--privateKey` in help — was echoed verbatim into `INVALID_KEY_REF` and replayed into the `WALLET_ALREADY_CONFIGURED` CTA, past the allowlist that exists to keep secrets out of envelopes. Redacted by shape now, in the message and in the replay, and the message names `--private-key` instead. Setups that had stopped working, and errors that were not what they said: - Keystore mode was gated on `isAgent()`, which is true whenever stdout is not a TTY — so `wallet balance --json | jq` and `wallet costs > costs.json` began refusing on installs where they had always worked. `cast` reads the password from /dev/tty; a pipe takes nothing away. New `canPrompt()` asks the question actually being asked. - An unrecognized provider prefix reached `isProviderAvailable()`, which cannot tell "does not exist" from "not installed", and was reported as a retryable PATH gap with a null install hint. An agent would retry a permanent misconfiguration forever. Now `UNKNOWN_KEY_REF_PROVIDER`, not retryable, listing the providers that do exist. Also narrows the keystore `try` to the `cast` call it diagnoses — the scrape sat inside it, so "no key found in the output" was reported as "Mac Mismatch means the password was wrong", which is the one thing it is not.

That is what an agent saw for the most common failure a vault-backed wallet has: installed, but not logged in. The obvious fix — move construction inside each command's try — would have made it worse. Those catches end in `out.fail('UPLOAD_FAILED', …)`, `'COSTS_FAILED'`, `'DATASET_LIST_FAILED'`, so a key that could not be fetched would be reported as an upload that failed: typed, and wrong. Throwing `Errors.IncurError` instead fixes all 15 commands at once, plus any command that does not exist yet, and needs no command edits. Codes are shared with the ones `walletPreflight` already emits for the same conditions — whether the guard caught it or the resolver did is an implementation detail, and the fix is identical either way. New at use time: `KEY_REF_RESOLUTION_FAILED` (provider ran and refused — explicitly not retryable, since every cause needs a deliberate act), `KEY_REF_NOT_A_KEY`, `KEY_REF_AMBIGUOUS`, `KEYSTORE_DECRYPT_FAILED`, `KEYSTORE_NOT_A_KEY`, `KEYSTORE_AMBIGUOUS`. **A leading `-` is no longer a legal reference.** `clawdi:--project` passed SAFE_REF and reached argv as `clawdi vault resolve --project`, so config steered the helper's own option parsing rather than naming a secret. Not arbitrary execution, but more than "only the reference comes from config" allows. A dash anywhere else stays legal — `FILECOIN-PRIVATE-KEY` still resolves. **`wallet init` refuses what no command could resolve.** It validated the `:` shape and nothing else, so `clawdi:MY KEY&touch x` returned `configured`, cleared the previous wallet, and left every later command failing with "re-run `foc-cli wallet init`" — pointing back at the command that had just accepted it. The check is shared with the resolver via `unsafeRefReason`, and the preflight applies it too so a config already holding one gets a CTA instead of a bare throw mid-command. **`--keyProject` on its own now does what both docs promise.** No branch consumed it: the command fell through to `already_configured`, wrote nothing, and reported success, so the caller believed a scope was pinned that never was and every command kept resolving against the provider's default project. It now re-scopes the configured reference. Without one it fails `KEY_PROJECT_WITHOUT_KEY_REF`, and combined with `--auto`/`--privateKey`/`--keystore` it is refused rather than shadowing them — answering a contradiction by quietly picking one is the same silent-ignore this removes. --- cli/src/client.ts | 91 ++++++++++------ cli/src/commands/wallet/init.ts | 96 +++++++++++++++++ cli/src/key-ref.ts | 119 +++++++++++++++++---- cli/tests/key-ref.test.ts | 97 +++++++++++++++++ cli/tests/preflight.test.ts | 20 ++++ cli/tests/synapse-commands.test.ts | 90 ++++++++++++++++ skills/foc-cli/references/key-injection.md | 29 +++-- 7 files changed, 479 insertions(+), 63 deletions(-) diff --git a/cli/src/client.ts b/cli/src/client.ts index b8ebe37..a222a93 100644 --- a/cli/src/client.ts +++ b/cli/src/client.ts @@ -1,6 +1,7 @@ import { execFileSync } from 'node:child_process' import { basename, dirname } from 'node:path' import { getChain } from '@filoz/synapse-core/chains' +import { Errors } from 'incur' import { createPublicClient, createWalletClient, type Hex, http } from 'viem' import { privateKeyToAccount } from 'viem/accounts' import config from './config.ts' @@ -15,6 +16,7 @@ import { providerNames, redactKeyLike, resolveKeyRef, + unsafeRefReason, } from './key-ref.ts' import type { OutputContext } from './output.ts' import { canPrompt, expandHome } from './utils.ts' @@ -26,6 +28,21 @@ type Problem = { retryable?: boolean } +/** + * "Reconfigure the reference", for the several ways a stored one can be broken. + * A wallet is configured (badly), so every suggestion carries --force or it + * would bounce off WALLET_ALREADY_CONFIGURED. + */ +function reconfigureRefCta() { + return { + description: 'Reconfigure the reference:', + commands: keyRefCtaCommands().map((cmd) => ({ + ...cmd, + options: { ...cmd.options, force: true }, + })), + } +} + /** * Cheap checks that must pass before a command can sign anything. * @@ -76,14 +93,7 @@ export function walletPreflight(c: { agent?: boolean }): Problem | null { // passed to --key-ref, and this message is the one place that mistake // would be echoed into a log.

Validation now refuses a value that is itself a private key — init and the preflight both, via the shared rule — and every surface that quotes a reference (resolver failures, the unknown-provider message, init's own results) redacts key-like runs first, a no-op for every legitimate reference. --- CHANGELOG.md | 1 + cli/src/client.ts | 4 +- cli/src/commands/wallet/init.ts | 20 ++++++--- cli/src/key-ref.ts | 25 +++++++++-- cli/tests/key-ref.test.ts | 48 ++++++++++++++++++++++ cli/tests/preflight.test.ts | 12 ++++++ cli/tests/synapse-commands.test.ts | 30 ++++++++++++++ skills/foc-cli/references/key-injection.md | 4 +- 8 files changed, 132 insertions(+), 12 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 411259c..d90c3f1 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -25,6 +25,7 @@ External key custody. `foc-cli` can now hold a *reference* to a key kept in a se - Call-to-action guidance only offers a key-reference method when that provider's CLI is actually installed on the machine — suggesting a tool the caller does not have is a dead end. The reference docs still describe every provider. ([#33]) - Key resolution accepts a `0x` + 64 hex value only when it stands on its own, and refuses output holding more than one. A loose match was the dangerous case: every 32-byte value is a valid secp256k1 key, so the leading 64 hex digits of a longer blob would have been accepted and signed with — as a different address — rather than failing. ([#33]) - Windows: an npm-installed provider helper is a `.cmd`, which is a script rather than an executable and cannot be launched directly (Node has refused to since the fix for CVE-2024-27980). Those are now run through `cmd.exe`, with references restricted to a character set the shell treats literally so a tampered config still cannot become command execution. Previously the PATH probe found the helper, the preflight passed, and the launch failed with `EINVAL` — reported as "not logged in / key missing / wrong project", none of which was true. ([#33]) +- A reference that is itself a private key (`clawdi:0x…` — the `--privateKey` mix-up with the provider prefix included) is refused at init and by the preflight rather than stored, and every message or result that quotes a reference redacts key-like runs first. A key is pure hex, so the character allowlist alone waved it through — stored under a field documented as safe to display, sent to the provider as a lookup name, and echoed verbatim into the use-time error envelope bound for the MCP result and the logs.
