SciDEX — Task: [Forge] Add pinned runtime capture and reproducibi

Extend SciDEX analyses to emit pinned runtime metadata and verification bundles that can be rechecked later. ## REOPENED TASK — CRITICAL CONTEXT This task was previously marked 'done' but the audit could not verify the work actually landed on main. The original work may have been: - Lost to an orphan branch / failed push - Only a spec-file edit (no code changes) - Already addressed by other agents in the meantime - Made obsolete by subsequent work **Before doing anything else:** 1. **Re-evaluate the task in light of CURRENT main state.** Read the spec and the relevant files on origin/main NOW. The original task may have been written against a state of the code that no longer exists. 2. **Verify the task still advances SciDEX's aims.** If the system has evolved past the need for this work (different architecture, different priorities), close the task with reason "obsolete: " instead of doing it. 3. **Check if it's already done.** Run `git log --grep=''` and read the related commits. If real work landed, complete the task with `--no-sha-check --summary 'Already done in '`. 4. **Make sure your changes don't regress recent functionality.** Many agents have been working on this codebase. Before committing, run `git log --since='24 hours ago' -- ` to see what changed in your area, and verify you don't undo any of it. 5. **Stay scoped.** Only do what this specific task asks for. Do not refactor, do not "fix" unrelated issues, do not add features that weren't requested. Scope creep at this point is regression risk. If you cannot do this task safely (because it would regress, conflict with current direction, or the requirements no longer apply), escalate via `orchestra escalate` with a clear explanation instead of committing.

Spec File

[Forge] Add pinned runtime capture and reproducibility verification for analyses

Goal

Make SciDEX analysis runs emit enough environment and execution evidence to be rerun later in an isolated environment. That means pinned runtime definitions, environment lockfiles, declared entrypoints, captured inputs, recorded output digests, and a verifier that can check whether an analysis still reproduces.

The output should be usable with local runtimes now and extensible to OCI / Apptainer / Nix-backed execution later.

Acceptance Criteria

☑ Analysis execution records capture runtime identity, environment lock, entrypoint, and input/output digests.

☑ A verifier exists that can re-check a completed analysis against its capsule manifest.

☑ At least one real-data analysis path emits reproducibility metadata automatically.

☑ Verification results are queryable from SciDEX and stored durably.

☑ The design leaves room for ReproZip-style capture or OCI/Nix execution backends later.

Approach

Extend the current runtime/executor path to emit reproducibility metadata on each successful run.

Record runtime identity using immutable digests or lockfile hashes instead of only human-readable environment names.

Implement a verifier command that checks presence and hashes of declared inputs/outputs and validates the pinned runtime reference.

Wire one existing mechanistic analysis or notebook path through the verifier.

Work Log

2026-04-10 09:25 PT — Codex

Created initial spec for pinned runtime capture and reproducibility verification.

2026-04-10 09:27 PT — Codex

Created the live Orchestra task and attached the real task id.

2026-04-10 12:20 PT — Claude (minimax:50)

Runtime environment digest computation - Added to forge/runtime.py:

- compute_environment_digest(runtime_name) - computes deterministic SHA256 digest
from conda environment package list (name, version, channel), ensuring same
environment always produces same digest
- get_runtime_environment_info(runtime_name) - returns comprehensive info including
digest, package count, python path, env name
- runtime_result_to_capsule_metadata(result, analysis_id, created_by) - bridges
runtime execution with capsule registry for automatic capsule creation

Extended RuntimeResult with reproducibility fields:

- environment_digest, environment_name, entrypoint
- input_artifacts, output_artifacts (lists for future use)

Modified run_python_script to automatically capture:

- Environment digest computed on each execution
- Environment name
- Entrypoint (script path)

Verified all Forge runtimes have deterministic digests:

- scidex: 362841c1dfdc6e1f36ed658057ae4071657fc6de0edbaf1453ebfbe5d1defcc3
- forge-base: dabd0d7257d5fe478e5c71d3901ff0c744ff9158ecacdddadf68ee4ae4f30df4
- forge-dataml, forge-genomics, etc. all have unique digests

Tested: run_python_script correctly captures metadata, imports work, API stable
Committed: forge/runtime.py (+145 lines)
Progress on acceptance criteria:

- ✓ Analysis execution records capture runtime identity, environment digest, entrypoint
- ✓ Environment digest computed deterministically from conda package list
- ❓ Automatic capsule creation on analysis completion - helper ready, needs wiring
- ❓ Verification results queryable - needs integration with capsule registry

2026-04-10 12:45 PT — Claude (minimax:50)

Added verify_capsule_runtime() to forge/runtime.py:

- Fetches capsule manifest from artifact registry
- Checks if runtime environment is still available
- Compares current environment digest against recorded value
- Verifies entrypoint file still exists
- Persists verification result via artifact_registry.verify_capsule()

Wired automatic capsule creation into scripts/run_mechanistic_de_analysis.py:

- Added --register-capsule option
- Added _create_analysis_capsule() helper function
- Pre-computes environment digest before re-execution
- Creates capsule after successful analysis with runtime metadata

Added API endpoint POST /api/capsules/{id}/verify-runtime:

- Uses forge.runtime.verify_capsule_runtime for full environment verification

Progress on acceptance criteria:

- ✓ Analysis execution records capture runtime identity, environment digest, entrypoint
- ✓ Environment digest computed deterministically from conda package list
- ✓ Automatic capsule creation on analysis completion - wired via --register-capsule
- ✓ Verification results queryable - /api/capsules/{id}/verify-runtime persists to DB
- ✓ Design leaves room for OCI/Nix backends (runtime-agnostic architecture)

Committed: forge/runtime.py (+150 lines), scripts/run_mechanistic_de_analysis.py (+80 lines), api.py (+20 lines)

2026-04-12 — Sonnet 4.6 (task:c98d7e1e)

create_capsule_from_runtime_result() added to forge/runtime.py:

- Takes a completed RuntimeResult, captures git HEAD, and calls register_capsule()
- Only registers on returncode == 0 (successful runs only)
- Returns capsule artifact ID to caller

auto_register_capsule parameter added to run_python_script():

- When True and run succeeds, calls create_capsule_from_runtime_result() automatically
- Stores returned capsule_id on RuntimeResult.capsule_id field

emit_reproducibility_capsule() added to forge/computational_analysis.py:

- In-process capsule emission for analyses not running via run_python_script
- Computes SHA256 digests of all 3 real AD seed datasets (genetic loci, biomarkers, trial failures)
- Computes output digest over all 30 findings
- Captures Python/package environment identity and git HEAD
- Registers a verified capsule artifact with full provenance

run_with_capsule() added as convenience entry point:

- Runs full analysis pipeline, emits capsule, returns (findings, capsule_id)
- Tested: 30 findings, capsule registered with real dataset digests + git SHA

Pushed: b732ed115 to main

Notes

The capsule capsule-4871c0a0-58d4-456a-893a-37bca128b24a shows environment_digest_mismatch and entrypoint_missing because:

The environment digest has changed since capsule creation (a different conda package state)

The entrypoint temp file no longer exists

This is correct behavior — the verifier correctly detects when the capsule's runtime environment no longer matches the current state. The capsule was created on a different worktree's environment and the temp file was cleaned up, which is expected.

Verification result is durably stored (returned by verify_capsule_runtime and visible in /api/capsules).

✅ Verifier exists — verify_capsule_runtime() callable with runtime-agnostic architecture
✅ Real-data analysis path emits reproducibility metadata automatically — emit_reproducibility_capsule(), run_with_capsule(), auto_register_capsule in run_python_script
✅ Verification results stored durably — verify_capsule_runtime persists to artifact_registry, queryable via /api/capsules
✅ Design leaves room for OCI/Nix backends — runtime-agnostic, not hardcoded to specific container tech

Attribution
