2026-10-21

00:15 plan, Claude Code (Opus 5.5): fmm approved the design (D76). Claude Code writes two plans: the record additions (skill 1.2.0) and the fair comparison.
00:27 build, Claude Code (Opus 5.5): fmm approved both plans (D77). M4 starts: the code tasks run subagent-driven in a worktree of claude-skills (branch record-additions).
02:26 build, Claude Code (Opus 5.5): Task 8 of the record plan: updated the skill files to 1.2.0 and filled in the record: decision times from the transcript (63 of 77), topics, four Replaces links, the Topics and Checks tables, release v0.0.1 with results H1 to H8, a draft of contributions.md (not approved) and the check list for D2 to D38.
02:27 build, Claude Code (Opus 5.5): End of milestone M4: replication-materials 1.2.0 is merged and pushed, this project uses it, and its record is filled in. The ledger is copied to plans/2026-10-20-record-additions-ledger.md. M5 (fair comparison) starts.
04:36 D78 04:36: Record the execution time of every scoring run (per image and per run, for JEV, Clef-Flash and CLIP) and report time per image for each method in the analysis document.
04:36 D79 04:36: Report the cost of each JEV call and configuration: the per-call log already holds tokens and an estimated cost; the analysis document sums it by configuration and per image, and the record compares the logged total with the TypeSafe account after the runs.
04:45 D80 04:45: In the interactive tables of the analysis document, stripe the rows by case study (dataset), not row by row.
10:42 D82 10:42: Platt calibration may reverse a method whose raw scores run backwards: keep standard Platt, report the Platt slope of every configuration, and mark each reversed configuration in the tables and the text, with its raw AUC next to it.
12:13 evaluate, Claude Code (Opus 5.5): Task 8 of the fair-comparison plan: fmm approved the loop instructions (D83) and a budget row of 50,000 JEV calls and USD 20 (D84). The code of Tasks 1 to 7b passed the final review. Next: the nine-image and latency checks, and a check-only rehearsal of the loop launcher.
12:13 D83 12:13: Approve the loop instructions scripts/fair_loop_instructions.md (filled into LOOP.md in each sandbox) as written.
12:13 D84 12:13: Approve up to 50,000 JEV calls for the fair comparison (loops, checks, calibration and test runs); the account holds over USD 20, so the budget row caps the cost at USD 20. This lifts the 7,000-call cap of D26 and the USD 5 budget of D44.
12:55 evaluate, Claude Code (Opus 5.5) with 8 isolated loop agents (Opus 5.5): Task 9: the 8 blind description loops ran, one agent per model and dataset; every audit has no call outside the sandbox; descriptions frozen (D85, D86). JEV calls: 1,248 for the loops and 4 for the checks.
15:42 D87 15:42: Run the one-time test runs of every configuration of design section 5.6 (JEV, Clef-Flash) and of the CLIP zero_final variant, after the calibration results.
17:09 evaluate, Claude Code (Opus 5.5): Task 10: the calibration runs, then the one-time test runs of all 56 decision-model configurations and the CLIP zero_final variant (D87), then the evaluation: P1 to P3, the reference curve, time and cost. JEV calls: 1,170 for calibration and 6,012 for the tests; none failed. Findings that change the text: D88 (JEV repeat runs), D89 (CLIP zero_final textiles). Next: the analysis document (Task 11).
22:19 D90 22:19: Push the branch fair-comparison and open a pull request to main. The merge waits for the approval of fmm.

18:11 D41 18:11: Make the research repository public, so the record website works on the free plan.
18:11 D42 18:11: License the repository under MIT.
18:12 inputs, Fadel M. Megahed: Set up the replication record.

18:20 D44 18:20: Set the JEV budget to about USD 5, the free credit for a new user.
18:24 D45 18:24: Use APA 7 style for citations, with the published metadata of each work.
18:26 D46 18:26: Use short, direct section headers in all documents.
18:37 D47 18:37: Make one Quarto document that reproduces all paper figures and tables; it reads saved predictions by default and has switches to re-run the paid and GPU steps.

18:37 D49 18:37: Use theme_bw with Dark2, annotations and a polished font; save each figure as PNG, PDF and SVG in one-column and two-column sizes.

20:37 D55 20:37: Publish figure F1 with its image sources on the figure; its AutoVI (pipe staple) tiles stay under CC BY-NC-SA 4.0.
20:37 D56 20:37: Keep beyond_clip_analysis.html in the repository and show it on the record website as an extra page (replication-materials 1.1.0).
20:51 paper, Claude Code (Opus 5.5): Updated the skill files to replication-materials 1.1.0 and published the rendered replication document on the record website (Analysis page).
20:54 D58 20:54: Also report CLIP with the learning sets of the CLIP paper at a threshold tuned like ours, next to the rule of that paper.
21:01 D57 21:01: Put "(Few-Shot)" in parentheses in the title: Beyond CLIP: Calibrated (Few-Shot) Defect Detection With Structured Decision Models.
21:03 evaluate, Claude Code (Opus 5.5): Tuned the threshold of CLIP with the paper learning sets by leave-one-out (local GPU, no API calls); added it to T4 and F3, with glyphs against the best CLIP result; wrote renv.lock.
21:09 D62 21:09: The benchmark is a CLIP baseline with 50 learning images per class (pans: 10), the low end of the abstract of the CLIP paper, with the defect images split evenly over the defect types; it replaces the best CLIP result as the reference of the glyphs, and the other columns stay.
21:09 D63 21:09: Add a dot-chart column to the interactive T4: one row per method, balanced accuracy on a common axis, dashed line at the CLIP baseline (inline SVG, no script).
21:18 evaluate, Claude Code (Opus 5.5): Ran the CLIP baseline (50 per class) for extrusion and microstructure (local GPU, no API calls); T4 now has the baseline as benchmark, glyphs and a dot-chart column; F3 has the baseline rows and a dashed baseline line.
23:25 D65 23:25: Do the redesign of the experiment and of its presentation on a separate branch (fair-comparison), not on main.
23:25 D66 23:25: Write R code in 80 to 90% tidyverse style (stringr for text) and use yardstick for the classification metrics; keep the code simple.
23:25 D67 23:25: Calibrate CLIP too, on the same images as the decision models, and test the calibrated CLIP model.
23:27 D68 23:27: Report accuracy, balanced accuracy, specificity, sensitivity, precision, F1 and MCC for each method.
23:29 D64 23:29: Tag commit 33ffd59 as v0.0.1 (pre-alpha) before any change to the code for the redesign.
23:32 brainstorm, Claude Code (Opus 5.5): Tagged v0.0.1 and started the redesign of the comparison (one label budget for all methods, calibration of all methods, all common metrics) on branch fair-comparison.
23:32 Tag v0.0.1 23:32: Pre-alpha. JEV tuned on validation and tested once; comparison with CLIP and Clef-Flash; calibration; the MSEC 2027 abstract and the replication document.
23:53 D69 23:53: Each method uses one learning set of 50 images per class (pans: 10) and one separate calibration set of 25 images per class; all methods use the same images (option B).
23:53 D70 23:53: The learning set of each dataset is its CLIP baseline set (pan_10, extrusion_50, textiles_50, pipe_staple_50, microstructure_50); the references of JEV and Clef-Flash come from it.
23:53 D71 23:53: Compare the methods with paired tests on the same test images.
23:53 D72 23:53: Add detail to the replication record: a timeline, the tags and the results.
23:53 D73 23:53: The record is an honest guide to the co-work with Claude Code and shows the intellectual contributions and decisions of the researchers.
23:59 spec-review, Claude Code (Opus 5.5): Wrote the design of the fair comparison and of the record additions (plans/2026-10-20-fair-comparison-design.md); a fresh reviewer checks it.
D74: The description loop is blind: its instructions carry no dataset knowledge from the researchers (not the hypotheses of docs/GOAL.md).
D75: The 37 back-filled decision rows (D2 to D38) show with the mark "not checked by a person"; fmm checks them before the tag v0.1.0.
D76: Approve the design plans/2026-10-20-fair-comparison-design.md, with the Claude calls of its section 13.
D77: Approve the plans plans/2026-10-20-record-additions-plan.md and plans/2026-10-20-fair-comparison-plan.md; run their code tasks subagent-driven, and the gated tasks with fmm in the session.
