Problem

When Pi crashes, for example when a user extension throws an uncaught error, T3 Code reports only Pi RPC read failed: pi process exited with code 1. packages/provider-pi/src/server/rpc.ts drained Pi's stderr and logged only its length, so the cause appeared in no log, no trace and no thread.

Reproduced on main (8760d063e9) with real Pi 1.4.0 and an extension that throws Error("This extension ctx is stale after session replacement"), loaded through Pi's launch arguments:

A crash at startup shows "Provider turn failed to start / Pi RPC read failed: pi process exited with code 1."
A crash mid-turn shows "Pi process exited unexpectedly."
In both cases the server log and server.trace.ndjson contain the exit code and nothing else.

Change

makePiRpcConnection keeps a bounded (4 KiB) tail of Pi's stderr. When stdout closes, it waits up to 250 ms for stderr to drain, in parallel with the existing 250 ms exit wait. It then puts a sanitized excerpt in a new PiRpcError.stderr field, which the message includes: pi process exited with code 1: <excerpt>. With empty stderr the message is unchanged. docs/internals/effect-services.md documents this field, together with ACP's existing AcpProcessExitedError.stderr, as a bounded exception to the rule that keeps process output out of error attributes.
ACP's stderr helpers move to @t3tools/provider-core/server/stderrExcerpt, so Pi and ACP share one sanitizer. The sanitizer reuses the secret-assignment rules that provider failure messages already apply, now exported as redactSecretAssignments.
Redaction is tightened so the excerpt stays safe (URL userinfo, query and fragment are stripped too):
- A truncated tail starts at the next line, so a secret's name is never cut off from its value.
- Authorization and x-api-key header values are redacted whole, including any scheme.
- Quoted values honour their own delimiter and backslash escapes; an unterminated quoted value is redacted to the end of the line.
- Header values are redacted to the end of the line, whatever the scheme, and URLs of any scheme lose their userinfo.
The thread text does not change for mid-turn crashes, which keep the curated message. Startup failures already show the nested error message, so they now include the excerpt; makeProviderFailure bounds it to 4096 characters and redacts it again.

What else changes:

ACP early-exit messages now read Authorization: [REDACTED] instead of Authorization: Bearer [redacted].
Provider failure messages redact Authorization: Token … fully. Before, only the word Token was redacted and the value leaked.
The per-chunk pi stderr debug log, which recorded only the length, is removed.

Scope and approval

Fixes pingdotgg/t3code#28653

Verification

Focused tests:

vp test run packages/provider-pi/src/server/adapter.test.ts -t "PiRpc early process exit": the new test "includes a redacted stderr excerpt when pi exits with an uncaught error" fails on main with expected 'pi process exited with code 1' to include 'This extension ctx is stale after ses…'. It passes here.
packages/provider-core/src/server/stderrExcerpt.test.ts adds regression cases for:
- compact JSON and quoted values with spaces, embedded quotes or escapes;
- env:API_KEY=;
- Authorization: Token;
- x-api-key with ;;
- truncation across split chunks, including a single long line;
- URL userinfo, query and fragment.
Passing: stderrExcerpt.test.ts, failure.test.ts, the full Pi adapter.test.ts, and apps/server AcpJsonRpcConnection.test.ts, CodexAdapterV2.test.ts and ClaudeAdapterV2.test.ts.
vp run check:changed passes: format, lint, knip, typecheck of 39 packages, 142 tests.
The redaction regexes are linear: at most 1.3 ms on 3000-repetition adversarial inputs of 21k to 66k characters. Real input is capped at 4 KiB.

Runtime transcript (real Pi 1.4.0, T3 dev server, fresh database, mid-turn crash):

Startup crash, thread error item, before 8760d063e9 and after 4327cdaa85. Later commits change only redaction and truncation. An independent rebuild at bfc9e7e7f3 differs only in the timestamp pixels.

Environment: T3 preview browser (Chromium 156, Linux), no device emulation, DPR 2, 100% font scaling; CSS viewport 1440×900 dark (exported at 1280×800) and 390×844 light. Diff0 is the absolute difference ×255; DiffT marks channel differences above 8/255. What else changed: the failure timestamp (1:17 PM → 1:20 PM). Every other pixel is identical at zero threshold.

F05 startup crash	Before	After	Diff0	DiffT (>8/255)
1440×900 dark	8760d063e9	4327cdaa85	8760d063e9 → 4327cdaa85	8760d063e9 → 4327cdaa85
390×844 light	8760d063e9	4327cdaa85	8760d063e9 → 4327cdaa85	8760d063e9 → 4327cdaa85

Driver used for the captures: fresh database per side (T3CODE_DEV_SEED=0), with Pi set up in settings.json as providerInstances.pi = {"driver":"pi","enabled":true,"config":{"enabled":true,"launchArgs":"-e <path>/stale-ctx-startup.ts"}}. One message sent from the web UI on a Pi thread. The extension crashes only when T3 opens a real session; the status probe runs with --no-session:

1	export default function (pi) {
2	if (!process.argv.includes("--no-session")) {
3	setTimeout(() => {
4	throw new Error("This extension ctx is stale after session replacement");
5	}, 0);
6	}
7	}

Not captured: other message shapes, banner interactions, mobile timeline and cards, and the side-chat pane. No renderer, component or CSS changes; only the text of one existing error item changes, on the startup-failure path. The web and mobile timelines already show multi-line messages up to 4096 characters from other providers, and native thread cards clamp their subtitle to one line. The mid-turn crash keeps its curated thread text, so it is proved by the transcript above, not by captures.

Walkthrough

Provider Core now provides shared stderr-tail and sanitization helpers. Pi includes sanitized stderr excerpts in process-exit errors. ACP uses the shared helpers in place of its ACP-specific implementation.

Changes: Stderr diagnostics

Layer / File(s)	Summary
Shared stderr handling `packages/provider-core/src/server/failure.ts`, `packages/provider-core/src/server/stderrExcerpt.ts`, `packages/provider-core/src/server/stderrExcerpt.test.ts`, `packages/provider-core/package.json`, `docs/internals/effect-services.md`	Provider Core exports shared stderr helpers and secret-assignment and URL redaction functions. Tail truncation keeps at most 4,096 characters and drops a partial first line. Tests cover secret redaction, path substitution, URL handling, and truncation. Documentation describes the stderr excerpt limit and sanitization.
Pi process-exit diagnostics `packages/provider-pi/src/server/rpc.ts`, `packages/provider-pi/src/server/adapter.test.ts`	Pi retains a bounded stderr tail and waits briefly for stderr draining when stdout closes. Its read error includes the exit status and sanitized stderr excerpt. Tests check that crash details are included and credentials are absent.
ACP shared stderr integration `packages/provider-acp/src/server/AcpSessionRuntime.ts`, `packages/provider-acp/package.json`, `packages/provider-acp/src/server/stderr.test.ts`, `apps/server/src/provider/acp/AcpJsonRpcConnection.test.ts`	ACP uses Provider Core’s tail and sanitization helpers. The ACP-specific stderr export and test file are removed. The process-exit test expects the full Authorization value to be redacted.

The description includes the required Problem, Change, Scope and approval, and Verification sections. It explains the issue, implementation, linked issue, focused tests, observed results, environment, and limitations. The Scope and approval section does not include an explicit maintainer approval comment, but the description is otherwise substantially complete.

Full details: Linked Issues check

Explanation

Issue #28653 requires that Pi stderr reach the diagnostic output when Pi exits, so that a crash cause is not lost. At head, makePiRpcConnection in packages/provider-pi/src/server/rpc.ts keeps a bounded stderr tail through appendStderrTail. When stdout closes, it waits up to 250 ms for the exit code and up to 250 ms for stderr to drain. It sanitizes the tail with sanitizeStderrExcerpt and stores it in PiRpcError.stderr. PiRpcError.message appends the excerpt after the exit detail. With empty stderr, the message is unchanged. The per-chunk stderr length log, which the issue identifies as the cause of the missing diagnosis, is removed. Startup failures show the excerpt in the thread. Mid-turn crashes keep their curated thread text, but the excerpt reaches the server log and trace, as the PR transcript shows. The issue does not request a specific thread text, so this design choice does not leave a stated requirement unmet. Automated tests cover the nonzero-exit excerpt, redaction, truncation, and the shared sanitizer. The issue's workaround (disabling the extension) is not a requested change.

Full details: Out of Scope Changes check

Explanation

The changes connect to issue #28653 or support its implementation. (1) Stderr tail capture, excerpt, and message change in Pi rpc.ts implement the issue directly. (2) The move of ACP stderr helpers to @t3tools/provider-core/server/stderrExcerpt.ts gives Pi and ACP one sanitizer. AcpSessionRuntime.ts and the package export change follow from this move. The deleted packages/provider-acp/src/server/stderr.test.ts covered the same helpers, and equivalent cases now appear in stderrExcerpt.test.ts. (3) Redaction changes in failure.ts (redactSecretAssignments, redactUrls, header and Token handling) are needed to make the excerpt safe. The sanitizer reuses these rules, so they also affect provider failure messages and ACP early-exit text. These effects are disclosed in the PR description and do not change unrelated product behavior. (4) The docs/internals/effect-services.md update documents the bounded stderr exception that the new field needs. No unrelated feature, UI, or renderer change is present in the diff summary.

fix(provider-core): redact AWS secret access keys and apostrophes in URL queries398a7b6

JJulius Marminge9d ago

On CodeRabbit's out-of-diff findings from the review of 76dd65ff03, checked against the current head:

AWS_SECRET_ACCESS_KEY: fixed in 398a7b6590. The secret-name list now includes access_key. Regression test: "redacts AWS secret access keys and apostrophe-quoted URL query values".
Quoted Authorization: 'Bearer …': already fixed in 865d35c347. Authorization: and x-api-key: values are redacted to the end of the line, whatever the quoting or scheme.
Unquoted values past , or ; (marked unverified): left as is. Ending an unquoted value at , or ; is long-standing behaviour of the shared provider-failure redaction. Running it to the next whitespace would also redact neighbouring a=1, b=2 fields in every provider's failure messages. Quoted values and header values, where such characters really occur inside a credential, are redacted in full.

fix(provider-core): redact secret assignments before URLs17ea2c5

Thanks, @juliusmarminge, for the earlier work and thorough investigation. Closing in favor of #33344 by @StiensWout, which addresses the same Pi crash diagnostics and is current. This PR’s head is over a week old and main has since changed its files.
