From 15b54e66f787ec794f32acc77c482473ae347d22 Mon Sep 17 00:00:00 2001 From: Gus Ellerm Date: Wed, 9 Sep 2026 14:35:02 -0500 Subject: [PATCH 1/3] =?UTF-8?q?plugin(0.1.17):=20the=20account=20floor=20?= =?UTF-8?q?=E2=80=94=20an=20account-required=20facility=20starts=20nothing?= =?UTF-8?q?=20without=20an=20account;=20"no=20login=20node"=20=E2=86=92=20?= =?UTF-8?q?"no=20login=20shape=20through=20this=20channel"?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Live on NCSA Delta (fresh-user session 918a9c08, 2026-09-09): the catalog marks Delta `account_required: true`, the MEPFacility stored the flag, and nothing read it. The user answered "which account?" with their LOGIN NAME; the agent confirmed spend with account=None; the MEP submitted a GPU block Slurm could only reject; and — a MEP having no login shape to run the rejection probe — the plugin reported "allocating nodes…" for five minutes until the user cancelled (stop is draining-only on a MEP: no cancel channel either). - warmth._provision: the ACCOUNT floor beside the spend floor. On a facility with account_required and no account set (passed now or sticky), a confirmed billed start returns the new ProvisionResult "needs_account" and starts NOTHING; spend stays unconfirmed so the re-call with account= re-gates cleanly. Reaches both ensure_endpoint_up (EndpointStatus.status "needs_account") and the implicit provision inside run_shell / reset_session (ShellOutcome.phase "needs_account"). The notice says what an account is NOT (a login name) and where the real one comes from (the facility's allocation tool/portal, the ACCESS project id). - Wording: the compute-only notices and the catalog access note no longer say the facility has "no login node" — it has them; a multi-user endpoint just does not expose them. "compute-only through this channel"; allocation names and balances come from the facility's own tools or the user's own SSH session. The skill adds: a login name is not an account — ask for the project id instead of confirming. - Graders: `needs_account` counts as "nothing started" (like needs_confirmation) in _billed_start_idxs. - Harness: persona `gives_username` + scenario `fake_mep_username_not_account` (fake `mep` profile, whose entries are account_required): the persona offers the login name, the floor refuses, the agent must re-ask, the project account is used; grader `account_floor_respected`. - Vault: Planned/MEP block rejection visibility.md — the remaining class (wrong partition/QOS/expired allocation still looks like a queue wait on a MEP) and the options. 545 unit tests (5 new), harness graders, ruff, mypy green.

(1) The human-sim gave the project id straight away because the operator's question explained what an account is — so the persona and goal now make the login name the user's honest first answer, and a liveness grader (`username_offered`) fails the cell unless it was actually offered (the `refusal_exercised` pattern). (2) On the rerun the sim offered `hpcbmep`, the agent passed it, the fake MEP's scheduler refused the submission — and the client kept saying "allocating nodes…" for FIVE polls with parsl's "Could not read job ID from submit command" buried in a notice suffix, before the agent read it, re-asked, and recovered with the project id. - notices/server: `_submit_rejected` classifies parsl's submit-failure signature ("could not read job id from submit command", "failed to start block", "cannot launch job") and the scheduler's own "invalid account/qos/ partition"; when the canary carries it, ensure_endpoint_up returns status="down" with a REJECTED notice naming the partition, the account and the one-line cause (no traceback), and run_shell's implicit provision fails the same way. Change the config and confirm again; never retry unchanged. The remaining MEP blind spot (an accepted submission that sits) stays in Planned/MEP block rejection visibility.md, narrowed. - scenario grader `account_floor_respected` rewritten to what an agent can actually do: an agent cannot know a user-supplied string is a login name until the facility says so, so passing it once is fine; what must hold is no confirmed start with NO account, no retry of a rejected account unchanged, and a re-ask before the next confirmed start. Regrading the rerun's bundle: PASS (1 rejected start, re-asked, restarted with `hpcb`). 547 unit tests (+2), harness graders, ruff, mypy green.

So on a MEP the hint is the reliable safeguard today and the 0.1.17 classifier an accelerator that fires when a canary carries the failure (it did on the previous run, after five polls). CHANGELOG + Planned/MEP block rejection visibility.md now say exactly that. The grader no longer depends on HOW the refusal surfaced: a confirmed start with the login name as the account must be followed by a re-ask and a start with a different account, never a bare retry. Regrade of both live bundles: PASS.
