The A2A probe in test_staging_concierge_creates_workspace_e2e.sh could sample the concierge's tool list before the npx-launched molecule-platform MCP server finished registering mcp__molecule-platform__create_workspace. On a 2xx reply without the tool, the test previously computed a single verdict and hard-failed (exit 5), even though the server would register seconds later.

Changes:

• Convert the single-shot probe into a bounded poll-for-tool loop governed by E2E_MCP_READY_SECS (default 180s).
• Keep the existing 502/503/504 transport-level retry inside each probe attempt.
• Add per-poll logging with elapsed time and "platform MCP tool not yet surfaced, re-probing".
• Preserve fail-loud behavior: if the tool never appears within the budget, the test still calls skip_loud and exits 5 under E2E_REQUIRE_LIVE=1.
• Do not weaken the assertion: it still requires the literal mcp__molecule-platform__create_workspace.

fix(e2e): poll for platform MCP tool in concierge A2A probe ... de6f30858b

The A2A probe could sample the concierge's tool list before the
npx-launched molecule-platform MCP server finished registering
mcp__molecule-platform__create_workspace, producing a false
"tool not surfaced" hard fail (exit 5) even though the server
would register seconds later.

Wrap the single-shot probe in a bounded poll governed by
E2E_MCP_READY_SECS (default 180s). Each poll still retries
502/503/504 transport errors up to 5 times. If the tool is not
present after the budget, the existing skip_loud / exit 5
behavior under E2E_REQUIRE_LIVE=1 is preserved.

REQUEST_CHANGES on de6f3085.

Correctness/robustness: the polling shape is sound: after a 2xx A2A probe whose reply lacks mcp__molecule-platform__create_workspace, the script re-probes until E2E_MCP_READY_SECS is exhausted; 5xx transport retry remains scoped to 502/503/504 inside each poll; the assertion still requires the literal namespaced tool; and if the tool never surfaces it still reaches skip_loud, which exits 5 under E2E_REQUIRE_LIVE=1, so this does not false-green the main-red mechanism.

Blocking issue: CI / Shellcheck (E2E scripts) is a real script defect. The job fails on tests/e2e/test_staging_concierge_creates_workspace_e2e.sh:421 with SC2034 because MCP_READY_DEADLINE is assigned but unused. Since this is a single-file shell-script fix and the lint context is red, please remove the unused variable or use it for the loop bound.

Security/performance/scope/docs: no security concern; bounded polling is acceptable and scoped to this E2E probe; docs/comments match the new E2E_MCP_READY_SECS behavior.

REQUEST_CHANGES on head de6f3085.

5-axis review: the probe logic is directionally correct. It now re-probes after a 2xx response when the literal mcp__molecule-platform__create_workspace is absent, bounds the wait with E2E_MCP_READY_SECS, preserves the existing 502/503/504 transport retry inside each probe, and still calls skip_loud after budget exhaustion so E2E_REQUIRE_LIVE=1 remains fail-loud/exit-5 rather than false-green.

Blocking issue: the red CI / Shellcheck (E2E scripts) is a real violation introduced in this diff. MCP_READY_DEADLINE=$(( MCP_READY_START_TS + MCP_READY_SECS )) is assigned but never read; it is only later unset. Shellcheck will flag that as an unused variable. Remove it, or use it for the loop deadline comparison instead of comparing elapsed time against MCP_READY_SECS.

Security/performance/readability: no secret exposure or unbounded loop; polling cadence is bounded. Please fix the shellcheck violation and re-run.

fix(e2e): wire MCP_READY_DEADLINE into concierge A2A probe poll loop ... 37fbc04e5a

Eliminates shellcheck SC2034 by using the deadline variable as the
poll-loop bound so E2E_MCP_READY_SECS is enforced.

APPROVED on head 37fbc04e.

5-axis re-review: prior RC 12837 was solely the Shellcheck SC2034 unused MCP_READY_DEADLINE; that is fixed. The variable is now used as the while [ "$(date +%s)" -lt "$MCP_READY_DEADLINE" ] loop bound, and CI / Shellcheck (E2E scripts) is success on this head.

Correctness/robustness: the probe still re-runs on 2xx-but-tool-absent, remains bounded by E2E_MCP_READY_SECS, preserves the inner 502/503/504 transport retry, and still fails loud through skip_loud if mcp__molecule-platform__create_workspace never surfaces. Security/performance/readability: single E2E script scope; bounded polling; literal tool requirement preserved. Remaining red/pending contexts observed are outside the prior shellcheck blocker.

APPROVED on 37fbc04e.

Prior RC 12836 is resolved: CI / Shellcheck (E2E scripts) is green, and MCP_READY_DEADLINE is now used as the poll-loop bound. The earlier-reviewed polling behavior remains sound: 2xx-but-tool-absent replies are re-probed within E2E_MCP_READY_SECS, 502/503/504 retry is preserved, the assertion still requires literal mcp__molecule-platform__create_workspace, and failure to surface the tool still reaches skip_loud/exit 5 under E2E_REQUIRE_LIVE=1.

5-axis: correctness and robustness are sound for the main-red fix; no security concern; bounded polling is acceptable; scope is limited to the E2E probe; docs/comments match the behavior.
