explain when allocation no longer needed\n- Do not reserve with dummy jobs or keep interactive allocation idle as precaution\n\n### **Data Access Rules:**\n- Read only data approved for this task and configured model service\n- Terminal output and file contents may be sent to model—redact minimally\n- Do not print full environment dumps or sensitive records\n- Preserve original evidence when diagnosing failure (keep logs, checkpoints, caches)\n- Investigate file availability/access/storage tier before bulk reads\n\n### **Shared Resource Rules:**\n- Keep searches and metadata operations narrow\n- Prefer bounded log excerpts to complete logs\n- A read-only recursive walk or repeated directory listing creates substantial load\n\n---\n\n## (4) Concrete Commands, PBS Directives, Script Requirements\n\n**No specific PBS directives, script headers, or concrete commands explicitly detailed in document.**\n\nGuidance provided:\n- \"Use an applicable approved PBS wrapper or successful script when available\"\n- \"Otherwise prepare a script from documented Aqua examples\"\n- \"Request the required resources and let PBS choose placement unless documented workload need requires otherwise\"\n- \"Keep scheduler-provided GPU visibility intact\"\n- \"Route PBS output, application logs, results, caches, temporary files to intended locations\"\n- Source environment setup in the shell that will run the program\n- For Python with `uv`: follow Aqua environment guide for environment and cache placement\n\n**Reference:** PBS Cookbook contains reusable helpers; inspect for side effects before running\n\n---\n\n## (5) Verification & Diagnosis Workflow Rules\n\n### **Monitor Only Authorized Runs:**\n- Use bounded read-only queries and existing monitoring tools\n- Choose reasonable polling interval; back off on errors\n- Do not create persistent watcher or recurring task without authorization\n- Say when monitoring ends\n\n### **Distinguish Job States:**\n\"Submitted, queued, running, failed, completed, and unknown states\"\n\n### **What Does NOT Prove Completion:**\n- Job disappearing from queue\n- Zero shell exit code\n- Checkpoint file alone\n- Log stopped growing (consider buffering, application phase, output path, scheduler state)\n- Successful wrapper (can still omit task or conceal application error)\n\n### **Diagnosis Workflow by Failure Phase:**\n\n| Observation | Investigation |\n|-------------|----------------|\n| Submission rejected | Read scheduler message; compare with limits, account requirements, syntax |\n| Job still queued | Inspect state; waiting alone ≠ broken job |\n| Exited early | Check init, working dir, input paths, environment, permissions, first error |\n| Hit resource/walltime limit | Confirm exit reason; propose justified request or recovery |\n| Log stopped growing | Consider buffering, application phase, output path, scheduler state |\n| Completion reported but results incomplete | Compare actual work/outputs with requested config |\n| Status/accounting unretrievable | Report as unknown; preserve last observation with time |\n\n### **Support Ticket Preparation:**\n- Concise summary: command, job ID, observation time, error excerpt, checks performed\n- Redact sensitive content; user must approve sending\n- Do not attempt to repair shared infrastructure\n\n### **Final Verification Report Must Contain:**\n- Action (what was prepared/executed, job IDs)\n- Observed state (verified scheduler and application state, with time)\n- Evidence (checks performed, expected outputs met?)\n- Locations (scripts, logs, checkpoints, results user can inspect)\n- Next step (unresolved issues or concrete actions needing approval, monitoring status)\n\n**Never fabricate job IDs, output contents, resource measurements, or successful checks.**\n\n---\n\n## (6) All URLs Referenced\n\n| Resource | URL |\n|----------|-----|\n| QUT Aqua overview | `https://docs.eres.qut.edu.au/about-aqua` |\n| Prerequisites | `https://zhipenghe.me/Walltime-Chronicles/tutorials/prerequisites/` |\n| Welcome to Aqua (Lesson 1) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-1/` |\n| Tooling setup (Lesson 2) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-2/` |\n| uv on Aqua | `https://zhipenghe.me/Walltime-Chronicles/remote-dev/uv-on-aqua/` |\n| QUT filesystems | `https://docs.eres.qut.edu.au/hpc-filesystem` |\n| Remote development | `https://zhipenghe.me/Walltime-Chronicles/remote-dev/Surviving-without-VS-Code-Remote-SSH/` |\n| Shared permissions | `https://zhipenghe.me/Walltime-Chronicles/remote-dev/Permissions-Dont-Move/` |\n| Interactive work (Lesson 3) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-3/` |\n| First batch job (Lesson 4) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-4/` |\n| QUT queue limits | `https://docs.eres.qut.edu.au/hpc-queue-limits` |\n| Resource sizing (Lesson 6) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-6/` |\n| Queue scheduling | `https://zhipenghe.me/Walltime-Chronicles/scheduler/The-Queue-Is-Not-a-Line/` |\n| Know Your Nodes | `https://zhipenghe.me/Walltime-Chronicles/scheduler/Know-Your-Nodes/` |\n| Walltime by Recipe | `https://zhipenghe.me/Walltime-Chronicles/scheduler/Walltime-by-Recipe/` |\n| When jobs fail (Lesson 5) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-5/` |\n| Job arrays (Lesson 7) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-7/` |\n| Long jobs (Lesson 8) | `https://zhipenghe.me/Walltime-Chronicles/tutorials/lesson-8/` |\n| Aqua cheatsheet | `https://zhipenghe.me/Walltime-Chronicles/cheatsheet/` |\n| PBS Cookbook | `https://zhipenghe.me/Walltime-Chronicles/pbs-scripts/` |\n\n**Access Note:** `docs.eres.qut.edu.au` URLs require QUT network/VPN"}

Login nodes are the SSH entry point for lightweight prep and\ninspection only; real work runs on compute nodes inside a scheduler allocation, interactive or\nbatch. Submitting a job is not running it — queue time is normal and is not evidence of failure.\nFilesystems differ in purpose, performance, quota, and retention, so a temporary compute location\nis never the only copy of anything that matters. A command that works in an interactive shell can\nstill fail unchanged inside a batch job, because the environment is not the same.\n\n## Action boundaries\n\nAsk for explicit approval, per specific action, before:\n\n- Any queue mutation: submit, cancel/delete, requeue, alter, hold, release — including when it\n  happens indirectly through a script, API, MCP tool, or SSH helper.\n- Any new allocation: interactive sessions, test jobs, arrays, replacement or dependency jobs.\n- Any retry or recovery loop. Approval to submit once is not approval to resubmit.\n- Deleting or overwriting files, recursive permission changes, storage-attribute changes.\n- Modifying shared environments, installing software, starting persistent services, changing\n  credentials, or uploading anything to an external service.\n- Closing an allocation, and sending a support ticket.\n\nAn approval request must carry the exact command or script, the resource request (CPUs, memory,\nGPUs, walltime), the job count or array range or job IDs, and the purpose and consequences.\nPropose concretely — show the script, working directory, and affected IDs — then ask.\n\nNever:\n\n- Weaken permission prompts, sandboxes, or access controls to get past a restriction.\n- Treat a filled-in config, an account capability, or a past task's approval as permission now.\n- Change permissions, HSM attributes, or timestamps to dodge retention policy.\n- Read credential stores, private keys, tokens, full environment dumps, or sensitive records.\n- Create persistent watchers or recurring tasks unasked.\n- Resubmit after a timeout without first inspecting scheduler state.\n- Bundle an unrequested repair into a diagnostic check.\n- Fabricate job IDs, output contents, resource measurements, or checks that were not run.\n\nNo approval needed, inside the authorized scope: reading files, preparing and editing scripts,\nlightweight local checks, and explaining or reviewing existing work.\n\n## Running work\n\nKeep training, benchmarks, inference, substantial preprocessing, and heavy tests off login nodes;\na small dataset does not make a workload appropriate there. Bound thread counts, workers, and\nconcurrent tasks to the allocation rather than to the physical CPU count, and account for nested\nparallelism. Reserve only what is needed, say when an allocation can be released, and never hold a\nreservation with dummy jobs or an idle interactive session.\n\nPrefer an approved PBS wrapper or a script that has already succeeded; otherwise build from the\ndocumented Aqua examples. Request resources and let PBS place them unless a documented need says\notherwise, leave scheduler-provided GPU visibility alone, and route PBS output, application logs,\nresults, caches, and temporaries to their intended locations. Source environment setup in the same\nshell that runs the program. For Python with `uv`, follow the uv-on-Aqua guide for environment and\ncache placement.\n\nReading and searching also load the shared system: keep metadata operations narrow, prefer bounded\nlog excerpts over whole logs, and check availability, access, and storage tier before bulk reads.\nRecursive walks and repeated listings are expensive even when read-only.\n\n## Verification and diagnosis\n\nMonitor only authorized runs, with bounded read-only queries, a reasonable polling interval,\nback-off on errors, and a clear statement of when monitoring stops.\n\nNone of these prove success: the job vanishing from the queue, a zero exit code, a checkpoint file,\na log that stopped growing, or a wrapper that returned cleanly while skipping a task or swallowing\nan application error. Distinguish submitted, queued, running, failed, completed, and unknown.\n\n| Observation | What to check |\n| --- | --- |\n| Submission rejected | The scheduler message, against queue limits, account requirements, syntax |\n| Still queued | Job state; waiting alone is not a broken job |\n| Exited early | Init, working directory, input paths, environment, permissions, first error |\n| Hit a limit | Confirm the exit reason, then propose a justified request or recovery |\n| Log stopped growing | Buffering, application phase, output path, scheduler state |\n| \"Done\" but results thin | Compare the work actually performed and outputs against the requested config |\n| Status unretrievable | Report it as unknown and preserve the last observation with its time |\n\nPreserve original evidence — logs, checkpoints, caches — while diagnosing. Do not try to repair\nshared infrastructure; prepare a concise ticket instead (command, job ID, observation time, error\nexcerpt, checks performed), redacted, and let the user approve sending it.\n\nClose out with: the action taken and job IDs; the verified scheduler and application state with a\ntimestamp; the evidence, including whether expected outputs exist; where the scripts, logs,\ncheckpoints, and results are; and the next step or anything still needing approval.\n\n## Command reference\n\nEvery `qsub` command and every PBS script header needs the project code (RPID) via `-P`.\n\nSubmission and control:\n\n| Command | Purpose |\n| --- | --- |\n| `qsub <script>.pbs` | Submit; prints the job id |\n| `qsub -I -l select=... -l walltime=... -P ABCDEF1234` | Interactive job on a compute node |\n| `qsub -W depend=afterok:<job-id> <script>.pbs` | Held until that job ends with 0 |\n| `qstat -u $USER` | Your queued and running jobs |\n| `qstat -xu $USER` | Yours, including finished |\n| `qstat -f <job-id>` | Every attribute of one job |\n| `qstat -Q` | Queues and their totals |\n| `qdel <job-id>` | Cancel; discards the queue wait it had earned |\n| `qalter -l walltime=04:00:00 <job-id>` | Change a queued job's walltime |\n| `qhold <job-id>` / `qrls <job-id>` | Hold and release your own job |\n\nDirectives:\n\n| Directive | Effect |\n| --- | --- |\n| `#PBS -P ABCDEF1234` | Project code — required |\n| `#PBS -N <name>` | Job name, and the log-file prefix |\n| `#PBS -l select=1:ncpus=4:mem=8GB` | Resources, per chunk |\n| `#PBS -l walltime=01:00:00` | Hard limit;

{"type": "text", "text": "Saved to `docs/aqua-guide.md`. It covers:\n\n- **System model** — PBS, login vs compute nodes, queue time isn't failure, filesystem and environment caveats.\n- **Action boundaries** — what needs explicit per-action approval (all queue mutations including indirect ones, new allocations, every retry, destructive file ops, shared-env changes, external uploads), what's never allowed, and what's free inside scope (reading, drafting scripts, local checks).\n- **Running work** — login-node limits, bounding parallelism to the allocation rather than the CPU count, script/output placement, and treating recursive reads as real load.\n- **Verification and diagnosis** — the list of things that do *not* prove success, a failure-symptom → check table, evidence preservation, and the required close-out report.\n- **Command reference** — qsub/qstat/qdel/qalter, `#PBS` directives with the required `-P` RPID, job states, exit codes (`-18`, `-29`, `137`, `143`), storage paths, module/uv commands, job variables, common errors.\n- **Where to read next** — every source URL from llms.txt, keyed by task.\n\nTwo notes on fidelity: the content is paraphrased rather than copied, because the agent guide itself caps quotes at ~125 characters. And the guide text doesn't mention the RPID requirement — I took that from the cheatsheet's `#PBS -P` entry and stated it as required, consistent with commit 5d2807c in this repo."}
