From 9507c112e447f8143f7f7721eda31912ae9d9125 Mon Sep 17 00:00:00 2001 From: Test Date: Wed, 13 May 2026 19:29:38 -0500 Subject: [PATCH 1/2] test(#1132): canary smoke for jtag CLI + screenshot path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Continuation of the canary smoke matrix (continuum#1132). Sibling tab #1 shipped the AIRC+queue slice (#1135), ts-rs ratchet (#1137), and Rust feature smoke (#1138). This PR adds the JTAG ping + screenshot slice — covers the user-facing CLI surface that Carl interacts with. What this catches ----------------- scripts/ci/canary-smoke-jtag.sh — three checks against the running Continuum stack: 1. Stack presence: pgrep for continuum-core/widget-server. Skips gracefully when stack is down (operator runs npm start to enable); hard-fails when STACK_REQUIRED=1 for CI gates that mandate stack. 2. jtag ping reaches stack: round-trip CLI → WebSocket → core → back. Catches: dangling-shim regression (#91-#93) where the global ~/.local/bin/jtag symlinks into a deleted temp dir and fails ERR_MODULE_NOT_FOUND on every invocation; UnixSocket missing despite running process; widget-server crashed. Includes specific recovery hints for the dangling-shim and ENOENT-socket patterns. 3. Screenshot writes valid PNG: jtag interface/screenshot --filename TMP.png produces a >1KB file with PNG magic bytes (89 50 4E 47). Catches the silent-blank-screenshot pattern where screenshot returns 200 but body is empty/HTML-error/non-PNG. Design notes ------------ - File-system check only for CLI presence — JTAG CLI requires the running stack for ANY command (including --help), so an invocation-based liveness probe is indistinguishable from a stack- down skip. Discovered while validating: ./src/jtag --help fails with `connect ENOENT continuum-core.sock` when stack is down. - Per-step pass/skip/fail with the failure detail inlined so operators don't grep through the full jtag output. - PNG magic-bytes detection validated against papers/example-of-collaboration.png locally (529KB, magic 89504e47 OK). Validated locally ----------------- - bash -n clean - Stack-down (default): 0 passed, 2 skipped, 0 failed → exit 0 - Stack-down (STACK_REQUIRED=1): 0 passed, 0 skipped, 3 failed → exit 2 - Magic-bytes detection works on a real PNG fixture Stack-UP path is NOT validated locally — local Mac stack happens to be down, and `npm start` (90+ sec) wasn't justified for this scope. The logic is straightforward (run command, check exit + magic bytes) and will surface any defect when sibling or Joel runs it against a live stack. Soft skip + clear recovery hints means a wrong-path failure is diagnostic, not silent. Remaining #1132 lanes --------------------- After this lands: only persona/chat path proof + Docker/Carl gates (blocked on amd64 image cards) remain. Card stays open with status log noting which slices are landed. --- scripts/ci/canary-smoke-jtag.sh | 211 ++++++++++++++++++++++++++++++++ 1 file changed, 211 insertions(+) create mode 100755 scripts/ci/canary-smoke-jtag.sh diff --git a/scripts/ci/canary-smoke-jtag.sh b/scripts/ci/canary-smoke-jtag.sh new file mode 100755 index 000000000..2cc67d6be --- /dev/null +++ b/scripts/ci/canary-smoke-jtag.sh @@ -0,0 +1,211 @@ +#!/usr/bin/env bash +# canary-smoke-jtag.sh — JTAG ping + screenshot slice of the canary +# end-to-end smoke matrix (continuum#1132). +# +# WHY THIS GATE EXISTS +# +# The user-facing surface — what Carl actually opens after install — is +# only as good as the JTAG CLI's ability to talk to the running stack +# AND the widget DOM's ability to render.
