Summary

Colab installs use --no-deps, so AutoArray’s new finufft dependency was omitted and install verification F failed. Install finufft>=2.4.0 for Galaxy/Lens and their HowTo setups, matching AutoArray’s Linux floor. Fit-only setups remain unchanged. Tracks #204.

API Changes

autonerves.setup_colab.setup() installs the CPU NUFFT dependency for Array-based projects. No signatures or notebook call sites change. See full details below.

Test Plan

• Six-project bootstrap witness: before fix 4 failed / 2 passed.
• Patched Nerves full suite: 258 passed, 1 existing skip (specifier comparison needs absent Fit/Galaxy sibling checkouts).
• Existing AutoArray CPU NUFFT parity: 7 passed (finufft 2.5.1, nufftax 0.6.1).
• Diff whitespace clean; exact published tree matches locally tested files.
• Required Python 3.12 / 3.13 GitHub CI.
• After separately approved merge: fresh candidate wheels, real install verification F and release integration; reconcile original Heart IDs. No Colab/wheel integration success is claimed from mocked command tests.

Full API Changes (for automation & release notes)

Changed Behaviour

• autonerves.setup_colab.setup(project, ...): Array-based project pip commands explicitly include finufft>=2.4.0 under --no-deps.

Migration

• No notebook edits or user-call changes needed. Existing callers receive the corrected dependency installation after updating Nerves.

Heart RED corrective-PR authorization

James approved this specific PR scope in the current session: authorization record.

Exact approved reason: install verification FAILED (testpypi; checks F). Published Heart timestamp rechecked: 2026-10-25T09:34:29.845384+00:00 (RED).

Reason → #204 → missing dependency in the explicit bootstrap → package-list correction plus six-project command witness. This PR addresses that causal defect; it does not claim official clearance. Sibling release validation FAILED (stage integrate) remains until fresh validation passes. No thresholds, accepted-missing exceptions, scoring weights or test gates changed.

Tier: judge — human /prm. Authorization permits commit, push and this one pending-release PR only. Merge, issue close, release and rehearsal are not authorized. Workspace impact: existing notebook callers need no migration; actual Colab validation remains part of the release-evidence follow-up.
