fix(server): preserve the warm Mol* frame across surface clears - #216
Merged
Conversation
…face clears
previewStructure cleared the persistent holder on every structure pick,
detaching the warm iframe; the next warm-path postToShell then hit a
null contentWindow ("Cannot read properties of null (reading
'postMessage')"). Clears now remove everything except the warm frame,
and a failed warm render disposes the dead shell so the retry
cold-starts cleanly.

… CI green, live-deployed
…ding state - toolbar stays above the preserved warm iframe (was pushed below the tall canvas on every warm mount) - disposal is acknowledged: the shell reports "disposed" after its own teardown and the parent detaches the iframe only then (2s timeout fallback), with a shell-side contract assertion - structure texts are cached per artifact (bounded: 3 files / 60 MB), so switching back to an already-viewed structure skips the download - quiet pulsing loading state for structure swaps and generic previews (reduced-motion aware) Co-Authored-By: Claude <noreply@anthropic.com>
The shell re-showed its "Preparing interactive structure…" spinner on every remount and the parent flashed a loading box on cached swaps — both are instant paths that read as a refresh. Warm remounts now keep the current structure visible while the next one loads, and cached swaps skip the loading box entirely; only first mounts show the loading state. Co-Authored-By: Claude <noreply@anthropic.com>
The first-time load now tells the truth about what is happening: the long phase (5 MB Mol* bundle download) reads "Downloading the Mol* viewer…", then "Preparing the interactive structure…" once the engine is booted — with a slow breathing glow behind the spinner as the visual signature. Warm/cached swaps still skip the loading state entirely. Co-Authored-By: Claude <noreply@anthropic.com>
…arkers
One awk module (docker/runners/common/stage_translate.awk) plus a tiny
per-family pattern file ("marker:regex") rewrites tool stderr phases
into the existing REVODESIGN_STAGE stdout protocol; original lines pass
through to the stderr log unchanged. AlphaFold2 ships markers for MSA
searching, featuring, modeling, and relaxation; the registry gains the
matching stage labels. Self-check: sample absl lines -> four markers,
noise line -> none.

The status line was written once at page load, so a task whose SLURM job started after the page opened kept showing "Queued" until a manual refresh. The page now polls every 15s, updates the status line live, and reloads once the task reaches a terminal state so the result manifest appears on its own. Co-Authored-By: Claude <noreply@anthropic.com>
…eued tasks
SLURM 19.05 does not reliably print srun's stderr banner in time, so
submit()'s 5-second wait fell back to a pid-based handle ("srun-12")
that was persisted as slurm_job_id — cancel and restart-recovery could
never reconnect such tasks, and they stuck at running forever. The
wrapper now publishes $SLURM_JOB_ID on stdout as its first line (the
allocation is authoritative), with the banner kept as a fallback. The
recovery pass now also covers queued tasks, marks tasks with non-SLURM
handles failed, and logs instead of dying silently on boot.
Co-Authored-By: Claude <noreply@anthropic.com>
The nested on_after_configure indirection never armed worker_ready in the production worker (0 receivers), so restart-recovery silently never ran. Connect the signal at module scope instead. Co-Authored-By: Claude <noreply@anthropic.com>
… squeue The unknown-state branch kept tasks running forever when sacct lost the job record (cancelled srun client). A live-queue probe now decides: alive in squeue -> re-queue poll; absent from both -> the job was cancelled during a restart, record the failure. Co-Authored-By: Claude <noreply@anthropic.com>
The probe used subprocess without the import — the recovery branch errored out and left the task running. Co-Authored-By: Claude <noreply@anthropic.com>
…rker The first stage was the runner's own launch echo; the actual phases are the translator-derived MSA searching, featuring, modeling, and relaxation. Drop the wrapper marker from both the registry and run.sh. Co-Authored-By: Claude <noreply@anthropic.com>

The test asserts exact source substrings, including a full array literal and a substring index ordering. A formatting change in
dashboard.jsortask-results.jsbreaks the test without any behavior change, and the test proves nothing about the polling behavior. The repository already runs JavaScript contract tests underserver/tests/js/. Executing the polling functions there would verify the terminal-status set, the in-flight guard, and the non-OK response handling directly.The
deleted:finshedvalue in the terminal list matches the preserved historical status, so no change is needed there. Based on learnings,deleted:finshedis intentional and must not be renamed.🤖 Prompt for AI Agents

- Around line 816-858: Update _recover_orphaned_tasks to handle in-flight SLURM
tasks identified by slurm_job_id instead of skipping tasks without container_id:
probe the scheduler and reattach when possible, otherwise transition the task to
a terminal failure or indeterminate state. Preserve the existing Docker recovery
branch and ensure orphaned SLURM records cannot remain indefinitely in running
or queued status after an unscheduled worker loss.

- Around line 1029-1041: Update the restart sweep to leave pending tasks
unchanged, while still handling queued and running tasks. In the inline script,
reuse the existing _finalize_failed_results helper instead of calling

- Around line 1017-1028: Source ENV_FILE in the parent shell before
pre_stop_sweep_slurm runs, then use ${RUNNER_USERNAME:-revodesign} when querying
