Summary

Phase 2 of epic linear-solver-programme on the profiling side (PyAutoArray#594; library fix PyAutoArray#595 merged 2026-09-30 as 7a89e19a0, pending release). The library now returns the #573 polished iterate as the raw-forward PDIP forward value. This PR records that in the solver programme: every scripts/lens/solver/ cell re-run against merged library main (device.provenance.library_revisions names PyAutoArray 7a89e19a0), the euclid latent cell's validation leg re-based from the pre-fix jit value 3.511093374 to the post-fix 3.320127604 measured on main, the ledger's Phase 2 section, campaign page + index row, and regenerated README tables.

Measured on the 81-system corpus: fixed pdip_raw equals phase 1's pdip_raw_polish on every metric on 81/81 systems — converged 81/81 incl. 48/48 SLaM, forward iterations median 18 / max 24 (+1–7 polish, accepted on all), worst inactive-column flux 3.31e-4 (pre-fix 0.115), worst total-flux error 3.31e-4 (0.115), worst source-flux error 4.96e-2 on euclid only (16.4; ≤ 4.9e-5 on the #571 fixtures), objective gap 8.2e-16, KKT 3.2e-16. Euclid latent +7.47e-5 vs eager (pre-fix +5.76e-2); the euclid pipeline latent test passes on library main. Under the pre-registered rule the fixed pdip_raw passes criterion 1 and still fails 2–4 for the recorded rule weaknesses (euclid source-column proxy far stricter than the latent it stands for; one flat-direction system at 0.219 shared by every accurate candidate; 5/52 KKT ratios at the 3e-16 floor) — the ledger says so rather than re-basing the rule.

Artefacts: the cells stamp al.__version__ = 2026.8.17.1 on a source checkout, so the re-run overwrote the *_v2026.8.17.1.{json,png} artefacts in place; they are "current library main" by contract, and the pre-fix versions live at 3ad68af and in the ledger's phase-1 tables. pdip_raw_tol_1e-2 (direct solve_nnls, no polish) now reproduces the pre-fix pdip_raw; the phase-1 sentence claiming it reproduces pdip_raw is annotated, not deleted.

Upstream PR

• PyAutoArray#595 — fix: return the polished raw-forward PDIP iterate as the forward value (#594) PyAutoArray#595 (MERGED, pending release)

Scripts Changed

• scripts/lens/solver/euclid_latent.py — PDIP_RAW_JIT_EXPECTED re-based to the post-#595 library-main jit value (comment names the PR, merge sha and the replaced pre-fix value); the JSON now records both the released and the library-main jit values
• scripts/lens/solver/_solvers.py — pdip_raw / pdip_raw_tol_1e-2 descriptions: polished forward value, forward-only iteration count; tol_1e-2 has no polish
• scripts/lens/solver/README.md, results/README.md (via build_readme.py) — regenerated tables; scripts/misc/tooling/build_readme.py — euclid renderer shows both jit values
• results/lens/solver/{accuracy,accuracy_posthoc,early_stopping}_summary_{all,slam_fixture_571}_v2026.8.17.1.{json,png}, euclid_latent_by_candidate_v2026.8.17.1.json — re-run against PyAutoArray 7a89e19a0
• results/notes/linear_solver_accuracy_2026_09.md — Phase 2 section; wiki/campaigns/linear_solver_accuracy.md, wiki/index.md — status, verdict, PRs, phase-2 row + journal entry

Test Plan

• ruff check . && ruff format --check . (250 files)
• build_readme.py --check, check_wiki.py --check, check_results_layout.py --check, build_dashboard.py --check, check_submits.py --check
• pytest scripts/misc/test -q — 984 passed, 5 skipped
• AUTOLENS_PROFILING_SMOKE=1 — the 7 lint.yml smokes + early_stopping.py + euclid_latent.py, all rc=0
• euclid_latent.py validation leg VALIDATES on library main (x_ref → eager rel −3.3e-8; pdip_raw → jit rel −2.0e-8)
• lint.yml green on the PR (incl. lychee, not run locally)

Heart RED override (development only)

• Authorization: live human in the Claude Code CLI session, 2026-09-30 ("do the workspace phase"; at the ship gate the human pushed feature/raw-pdip-forward-polish directly, ~18:55 BST, in response to the reported RED reasons). Scope: development shipping (push + this PR); merge only via a separate /prm on all-green required checks; no release.
• Heart readiness at the 18:50 BST gate (verbatim): RED PyAutoGalaxy: CI failure; RED release validation FAILED (stage integrate); YELLOW workspace validation not passing (0 failed, 1 timeout, cloud#36404726969: autolens_test scripts/multi_dataset/rectangular.py); YELLOW manifest drift: public front-door organ tables (generated) — 1 mismatch(es) vs PyAutoMind/repos.yaml. None involve autolens_profiling. This PR does not repair Heart; Heart remains RED for release.
• Passed branch gates at ad365df: ruff check + format (250 files); build_readme / check_wiki / check_results_layout / build_dashboard / check_submits --check; pytest scripts/misc/test 984 passed / 5 skipped; 9 smokes rc=0; euclid_latent validation leg validates on library main; in-session review (supervised, human-approved plan).
