GitHub Project\nfields are informational. Read `AGENTS.md` and applicable repository instructions.\nThe selected model route is fixed for this run. A changed model label requires a new run.\nFailed tests, missing evidence, provider errors and unresolved product defects are\nproblems to fix or plan around. If you cannot make progress, record what you tried in the\nworkpad and end the attempt as blocked (see \"Blocked attempts\"). Never add\n`symphony:critical`, a model route, or an Astra permit yourself.\n\nThis is attempt 1 of 3 for this issue. Nothing is parked: an attempt either\nadvances delivery or ends blocked and is retried later behind other work.\n\nIssue number: 791\nURL: https://github.com/ahammer/metalrain/issues/791\nTitle: Execute the 1D Stefan phase-front solver case\nDescription:\nParent tracking issue: #786\n\n## Problem\n\nThe retained Stefan row lacks a production fixed hot reservoir/adiabatic slab setup and exact completed phase-front, latent and thermal energy observations.\n\n## Scope\n\nImplement the declared one-row solid-liquid slab with production thermal and phase-change controls, physically calibrated tick/cell units, and completed production observations/ledgers.\n\n## Acceptance\n\nExecute the declared 8192-tick phase front and refinement trend, compare front position and energy ledgers against retained thresholds, and retain exact-source GPU/numerical evidence and focused tests with honest failure status.\n\nRun focused tests and `cargo xtask ci worker`. Use the Symphony delivery command and preserve the wider solver gate as incomplete. This issue is one independent case of #786; closing it does not close #786.\n\n\n\n## Start or resume\n\n1. Read the current issue and comments with `github_api` or authenticated `gh`.\n If the issue is closed or `symphony:ready` is absent, stop without modifying it.\n2. Find or create exactly one comment marked ``. Keep its\n acceptance criteria, plan, observed results, evidence keys, PR and blockers current.\n Resolve multiple existing workpads before proceeding. If the workpad records a blocker\n from an earlier attempt, first check whether it still holds, then work around it or take a\n different approach instead of repeating the failed one. Remove any leftover\n `symphony:needs-attention` label.\n3. Inspect Git status and existing PRs. Continue the linked open PR and its exact\n branch. For new code work, fetch main and create `symphony/issue-791`.\n If implementation is already merged, verify all issue acceptance on exact current\n main; do not manufacture a new PR just to close the issue.\n Never reset dirty source, force-push over another contributor, or reuse a closed\n branch without first reconciling its disposition. An uncertain publication is\n observed remotely before retrying it.\n4. Use `METALRAIN_REFERENCE_ROOT` for the frozen baseline; validate it with\n `cargo xtask reference status --require-present` before reference-derived work.\n `METALRAIN_LEGACY_ROOT`, when set, is additional read-only historical context.\n\n## Shared workstation\n\nUp to three Symphony agents share this workstation. One machine lease serializes heavy work:\nbuilds, tests, GPU work, the desktop and measurements.\n- `cargo` takes the lease automatically. Wrap every other heavy or desktop command in\n `machine-lease run -- `: a built binary run directly, GPU probes, the native\n preflight, measurement scripts. Keep heavy work in the foreground of that command.\n- A waiting command prints who holds the lease. Waiting is normal: do not kill it. If it\n gives up (exit 75), rerun it.\n- A running headed Sandbox holds the lease for its lifetime. Stop it as soon as the journey\n is done and before running the delivery command; heavy commands you start while it runs\n w…","kind":"prompt"},{"id":"msg_061e033654e254b1016ab9800aa39087d0af51bd10dbf2aa34","status":"completed","at":"2026-09-27T20:45:59Z","part":null,"started_at":"2026-09-27T20:45:58Z","text":"I’ll check the issue and repository state, then trace the Stefan case to its production owners.

`20578ed72084e035bbafdfc288bded35a12e75a8`, clean `symphony/issue-791` PR #801, with `METALRAIN_SOLVER_SOURCE` set to that full SHA when Cargo built `xtask` and runtime. The runtime-owned manifest hash and build attestation are in `stefan-report.json`. The retained source was compiled in the issue's external scratch target; the scratch target is disposable.\n\nEnvironment: Linux x86_64, Rust/Cargo 1.97.0, NVIDIA GeForce RTX 3090 via Vulkan. `environment.txt` and exact completed GPU sample reports identify the host and adapter. This is Shared correctness evidence, not a quiet performance measurement.\n\n## Acceptance criteria\n\n1. **Production one-row solid-liquid slab and calibrated controls — PASS.** The checked-in authored fixture compiles through the canonical content bundle. Production spawn creates a 300 K fixed thermal reservoir, a single row of 260 K solid, and nonconducting walls that confine melted liquid. Production thermal and fusion passes run with two liquid iterations. Fine cells are 250 micrometres with 250-microsecond ticks; coarse cells are 500 micrometres with one-millisecond ticks. Each run covers 2.048 physical seconds. The equal-capacity conduction rate of 9/1000 gives a nominal 1.125e-6 square-metre-per-second diffusivity. The content policy test passed.\n2. **Declared phase front and refinement — PASS.** `METALRAIN_SOLVER_SOURCE= cargo xtask solver verify-stefan --json` executed 8192 fine resident ticks (terminal completed tick 8193) and 2048 coarse resident ticks (terminal completed tick 2049). Fine front: 7 cells = 0.00175 m. Coarse front: 3 cells = 0.0015 m. Fine versus twice coarse differs by 1 fine cell; fine quarter-time front is 3 cells, so the square-root-time comparison also differs by 1 fine cell. Both satisfy the retained <=2-cell threshold. Exact completed sample fronts are retained at initial, one-eighth, quarter, half, and terminal time. `inspection.txt` independently checks monotonic samples and identities.\n3. **Latent and thermal energy observations and ledgers — PASS.** Every completed resident tick had thermal closure, balanced finite transfer and reservoir receipts, and conserved water-equivalent mass. Fine cumulative latent debit is 2,338,000 mJ = 7 x 334,000 mJ, latent credit zero, and reservoir heat 70,420,417 mJ. Coarse debit is 1,002,000 mJ = 3 x 334,000 mJ, credit zero, and reservoir heat 33,767,806 mJ. Exact-source full resident thermal field totals equal the completed ledger after-total at each post-initial sample; the fixed reservoir is at least 300 K at each sample. The report retains GPU adapter, source build, simulation identity, generation, query request, pass and resource facts. The measurement reports `passed` and `bounds_passed=true`.\n4. **Focused tests and worker validation — PASS.** The isolated content policy test passed 1/1; runtime verification-gate tests passed 3/3; the ignored production GPU ice fusion recovery test passed 1/1. `cargo xtask ci worker` passed workspace format and all-target checks. Documentation self-tests, workspace-reference check, and contract self-tests passed. Logs and exit records are retained for each command.\n5. **Wider solver gate and delivery — INCOMPLETE BY DESIGN.** The focused command returns exit 1 after emitting a passing Stefan measurement because `gate_status=incomplete` and `decision=null` remain explicit. Other numerical cases, variants, hardware and parent #786 are outside this issue. PR #801 is submitted to the Symphony delivery command for independent review; no broader solver acceptance is claimed.\n\n## Retained artifacts\n\n- `stefan-report.json`, `stefan-stderr.log`, `stefan-exit.txt` — exact-head GPU/numerical report, build/run log and expected gate exit 1.\n- `inspection.txt` — independent read of retained JSON, source, sampled field totals, adapter, fronts, latent receipts, and bounds.\n- `content-test.log`, `verification-gate-test.log`, `fusion-gpu-test.log` with corresponding `-exit.txt` files — focused checks.\n- `worker-ci.log`, `docs-check.log`, `workspace-reference.log`, `contracts-check.log` with corresponding `-exit.txt` files — required worker and repository-contract checks.\n- `environment.txt` — exact clean SHA, operating system and compiler versions.\n- `native-test-long-path.log`, `native-test-short-alias.log` — delivery-only AF_UNIX temporary socket path failure reproduced with the long external scratch spelling (exit 1), then passed 6/6 through a short symlink whose target remains the required external issue scratch directory. No source guardrail changed.\n\n## Delivery environment repair\n\nThe first delivery candidate passed source checks, workspace tests and doctests but its native Wayland unit test failed to bind an AF_UNIX socket because the helper supplied a long external scratch path as `TMPDIR`. The same test reproduced with that path and passed 6/6 with `TMPDIR` pointing through a short `/run/user//m791` symlink to the same external issue scratch directory. The retry uses that alias only for temporary-path spelling; the stored files remain under the required evidence scratch root.\n\n## Honest skips and limits\n\n- No headed accessibility journey: no user interaction or product UI changed.\n- No FullRender/debug-layer video: this delivery adds an isolated numerical fixture and does not alter a product presentation. The exact completed front trajectory samples and GPU reports are retained as motion diagnostics. This does not satisfy the parent gate's separate FullRender/debug motion obligation.\n- No performance claim or quiet-window measurement; issue acceptance is numerical correctness.\n- The complete solver verifier and unrelated hardware/variant cases were not rerun; their statuses remain governed by #786 and the other selected issues.\n\n## Pre-existing failures\n\nNone claimed. The solver command's exit 1 is its explicit incomplete-gate contract, not a pre-existing check failure.\n\n## Outcome\n\nStefan case acceptance is met for this exact head. The wider solver gate and #786 stay open.\nmachine-lease: waiting for the machine lease held by GH-788 since 2026-09-27T13:41:13-0700 (pid 809656): /home/adam/.cargo/bin/cargo xtask ci delivery.

The live acceptance journey\nis defined in [Symphony operation](symphony.md).\n\n## Scenario gate\n\n`cargo xtask scenarios` runs every checked-in scenario through the headless Scenario Harness on the\nlocal GPU. Each scenario reports named checks with measured values and thresholds. A scenario source\nmay declare `expect-fail CHECK REASON` for known physics or evidence debt, or `expect-fail run REASON`\nfor a scenario that cannot yet complete: that failure is accepted and stays visible, while an\nundeclared failure, a declared failure that now passes, or a declaration naming no reported check\nrejects the gate. Remove a declaration in the change that fixes it.\n\nConsumers observe and change the world through bounded GPU-backed commands and queries, never a\nsecond full CPU copy. `cargo xtask contracts check` ratchets the remaining per-tick CPU copy call\nsites outside the runtime; the allowance may only shrink.\n\n## Product and measurement evidence\n\nOrdinary GPU correctness runs on the local workstation. Performance and memory acceptance require\na quiet measurement window and recorded environment. Never stop unrelated processes to obtain one.\nAn interfered run is diagnostic; a required clean result remains incomplete until it can be measured.\n\nChanged visible or interactive behavior needs comparable captures and typed action/expected/observed\nsteps. Prefer deterministic headless production capture; interaction claims also require native\naccessibility. Check keyboard navigation, accessible names, narrow reflow and zoom where applicable.\nPair FullRender with matched-tick debug layers. Use GIF or MP4 for motion claims; stills do not prove\nmotion. Stop verification processes and confirm cleanup. No visual/performance baseline or reference\npin changes without explicit maintainer authorization.\n\n## Native Wayland display preflight\n\nReuse the logged-in ordinary-user session. A live Wayland socket alone does not establish a usable\ndisplay. With every monitor disconnected, KWin can expose no `wl_output`, accept the first surface\ncommit, and never deliver its frame callback. Sandbox can then expose Running/Tick 0 or Pausing/Tick 0\nthrough AT-SPI while its pixels retain the launcher. The displayed tick comes from the last presented\nsession; it does not establish that GPU simulation stopped.\n\nBefore a headed journey, run the preflight and retain its JSON record with the GPU/driver identity.\nOn the shared Symphony workstation it runs under the machine lease, like every desktop command\n(see [Symphony delivery](symphony.md#concurrency-and-the-machine-lease)):\n\n```text\nmachine-lease run -- /usr/bin/python3 tools/native-wayland-output.py preflight --fixture-log NEW_EXTERNAL_LOG_FILE\n```\n\nThe preflight wakes KDE outputs (`kscreen-doctor --dpms on`), requires an enabled, connected output\n(`kscreen-doctor -o`), and requires the `ydotoold` input socket (`YDOTOOL_SOCKET`, default\n`$XDG_RUNTIME_DIR/.ydotool_socket`) for keyboard and pointer gestures. When no output is connected it\nstarts the virtual display fixture below, gives the portal consent by keyboard once AT-SPI shows the\nportal dialog is the active window, and reports the fixture's process as `virtual_output`.

A package here may depend only on other reusable crates and approved external dependencies, never on `products/`, `tools/`, or `legacy`.\n- Use `metalrain-*` package names and inherit workspace version, edition, Rust version, authors, license, repository, and lints.\n- Keep crate fronts narrow and semantic. Public definitions live in their owning module; do not add\n crate-root re-exports, preludes, compatibility aliases, or facades for navigation convenience.\n- Colocate owned Rust, WGSL, schema declarations, generated contracts, fixtures, tests, and focused documentation. Generated output needs one declarative source and a freshness check.\n- Use modules until a dependency firewall, separately validated contract, or deployment boundary proves that a new crate is warranted.\n- Public APIs document responsibility, allowed dependency direction, identities, readiness/failure behavior, and a minimal integration example.\n- Production code owns product behavior. A tool or product may expose and verify it but must not contain the only implementation.\n# Authored content instructions\n\n- `content/` contains versioned human-authored source packages, not generated bundles, runtime caches, captures, or mutable user data.\n- Every package records semantic identity, source version, provenance, imports, and its owning compiler/profile. Generated products retain a source fingerprint but are not edited as source.\n- Production-natural geometry and environmental structure must derive from recorded seeded fields, simulation state, or relationships among them. Do not author landmarks, showcase-seed repairs, exact masks, contours, paths, silhouettes, or reserved natural regions.\n- Explicit level/gameplay geometry uses an `AuthoredFixture`-style profile and must not weaken production-natural validation.\n- Keep source, editor-view state, compiled programs, bundles, and runtime state as distinct representations. Saving source and exporting generated output are separate actions.\n- Treat the content tree as a normalized source database: one canonical record per concept, stable\n short-name keys, references instead of embedded copies, and separate set manifests as indexed\n views. Directories expose ownership and cardinality; compilers enforce uniqueness, referential\n integrity, graph closure, and deterministic discovery.\n- Each material has one simulation record and one side-by-side rendering/PBR record joined by its\n short-name. Simulation owns phase, conserved properties, transitions, reactions, and solver rules.\n PBR owns surface and volume channels, including emission; lighting consumes that emission rather\n than duplicating authored lights. Material sets reference library records, and products select sets.\n- Product north stars communicate relationships and direction; they are not renderer evidence, feasibility proof, or visual baselines.\n# Repository tool instructions\n\n- `tools/` contains repository automation and narrowly scoped support programs. It may depend on reusable crates; production crates never depend on tools.\n- Tools expose deterministic, cross-platform commands with stable help, explicit inputs, typed exit status, and non-overwriting output paths.\n- Check commands are read-only. A mutating command must advertise its action with a verb such as `write` or `install` and limit changes to its declared owner.\n- Never hide a product fix, production algorithm, reference compatibility path, or baseline update in tooling.\n- Repository checks derive facts from Cargo metadata, tracked files, canonical registries, and instruction discovery rather than fixed historical package counts.\n- Split checks by governed contract. Keep process execution, repository traversal, and temporary-test\n state in named owners rather than a generic utility module.\n- Tests use temporary directories and repositories; they do not alter the caller's Git configuration or tracked workspace state.\n","status":"completed","at":"2026-09-27T20:46:28Z","started_at":"2026-09-27T20:46:28Z","kind":"command","exit_code":0,"summary":null,"duration_ms":0,"output_truncated":false},{"id":"msg_061e033654e254b1016ab9802da15087d0b8a8e5b8874249ed","status":"completed","at":"2026-09-27T20:46:34Z","part":null,"started_at":"2026-09-27T20:46:33Z","text":"The branch is clean and already contains the implementation plus the requested motion capture.
