Concrete Deliverable

Add a configurable output buffer setting for system command user functions.
Pass the setting to Node child_process.exec as maxBuffer.
Preserve existing timeout, cwd, env, and shell behavior.
Document the setting and the maxBuffer error path.
Provide settings coverage plus apply instructions and verification notes.

Implementation Evidence

File	Prepared change
src/core/functions/user_functions/UserSystemFunctions.ts	Passes `maxBuffer` into `exec` and converts MB to bytes.
src/settings/Settings.ts	Adds default/schema/UI validator for `command_max_buffer`.
src/settings/SettingsV1.ts	Allows older settings data to carry the optional field.
docs/src/settings.md	Documents the new settings control.
docs/src/user-functions/system-user-functions.md	Explains the stdout/stderr maxBuffer error and fix setting.
test/specs/settings.e2e.ts	Adds settings UI coverage for changing the value.

Local checks:
1. git diff --check
Result: passed with no whitespace errors.

2. Node child_process default-buffer reproduction:
Command behavior: execute a child Node process that writes 1,100,000 bytes to stdout with default exec options.
Result: default_exec_error=stdout maxBuffer length exceeded

3. Node child_process custom-buffer proof:
Command behavior: execute the same child process with { maxBuffer: 2 * 1024 * 1024 }.
Result: large_stdout_with_custom_maxBuffer=1100000

4. pnpm install --frozen-lockfile
Result: not completed. npm registry metadata and attestation requests repeatedly timed out for packages including 7z-wasm, @codemirror/state, @codemirror/view, @electron/get, and @esbuild/aix-ppc64. The install was interrupted after repeated retries to avoid leaving a stalled session.

Full typecheck/build status:
Not run because dependencies were unavailable after the registry timeouts above.

Money boundary:
This is a prepared non-bounty patch and offer asset only. It is not payment proof. Confirmed money remains $0 until a real buyer accepts scope and an external payment or funded milestone is verified.

Exact Claim Steps

Open the source issue and confirm it is still open.
Review the local patch and verification output on the shared machine.
Add only your seller-owned checkout, invoice, marketplace order, funded milestone, or payment-request URL.
Use the draft response only after you approve it.
Require the exact acceptance sentence before payment.
Deliver the patch only after external payment proof or after you explicitly decide to publish it unpaid.
Record buyer scope, payment reference, amount, fees, refund/hold state, delivery URL or PR URL, acceptance, payout/payable/cleared status, and date.
Count $0 until the external proof shows posted, released, payable, cleared, credited, or verified net money.

Exact Acceptance Before Payment

I accept the Templater stdout maxBuffer Sprint fixed-scope terms at $100. I understand work starts only after seller-owned external payment proof exists; I will provide only public or buyer-authorized code and non-sensitive requirements; the deliverable is limited to the prepared configurable output-buffer patch, settings UI/default/schema update, docs note, e2e settings coverage, apply instructions, and verification notes; and private vault data, credentials, payment data, secret logs, public posting, pull requests, or ongoing revisions are not included unless separately agreed before payment.

Hitting stdout maxBuffer length exceeded on system commands

Open issue reports large system-command stdout failing under Node's default exec buffer.

Draft response not posted

I prepared a small patch for the system command stdout maxBuffer issue. It adds a configurable Output buffer limit setting, stores it as command_max_buffer in MB with a 10 MB default, passes maxBuffer into child_process.exec, documents the new setting, and adds settings coverage. A local Node smoke test reproduces the default stdout maxBuffer failure at 1.1 MB and confirms the same command succeeds with a larger maxBuffer. I can hand over the patch or adapt it to your branch after fixed-scope acceptance and external payment proof.

Draft response prepared only. External comments, emails, direct messages, pull requests, or patch delivery require explicit send approval.
