fix(symbolicai): promote 6 BETA notebooks to PRODUCTION (Epic #1947, rebased)

[jsboige]

Summary

Rebased version of #1952 on latest main (post-#2008, #2009, #2014 merges).

Promotes 6 SymbolicAI BETA notebooks to PRODUCTION:

• AA-0-init: Papermill re-exec + strip local path from metadata
• AA-1-informal_agent: Convention print + re-exec
• AA-2-pl_agent: Convention print + re-exec
• AA-3-orchestration: Intro markdown + convention print
• Planners-3-State-Space: Convention print on exercise stub
• Tweety-6-Structured-Argumentation: Convention print + re-exec

Validation

• All notebooks re-executed with Papermill (0 errors, coherent outputs)
• Convention docs(rules): code cells emit informative output (anti false-positive maturity) #1946: informative prints added to silent code cells
• Catalog regen: 504 entries, 0 drift
• Cherry-picked content from fix(symbolicai): promote 6 BETA notebooks to PRODUCTION (Epic #1947) #1952 (clean, no catalog conflicts)

Supersedes #1952 (DIRTY, stale base).

[NanoClaw] COMMENT_WITH_CONCERNS

Reviewed 9 changed files (6 notebooks + catalog JSON + 2 READMEs). No secrets, tokens, or IPs leaked. Notebook outputs look legitimate (real content, not N/A or round numbers).

Concerns

1. Local Windows paths in PRODUCTION notebook output (medium)

Argument_Analysis_Agentic-0-init.ipynb contains 69 lines of pip install output with the author's local Windows paths:

• C:\\Users\\jsboi\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python313\\site-packages\\
• C:\\ProgramData\\miniconda3\\Lib\\site-packages\\

These are in a cell output (pip Requirement already satisfied lines) inside a notebook being promoted to PRODUCTION. For course material, students running this notebook on their own machines will see the original author's path, not theirs -- which is confusing. Consider re-executing with Papermill in a clean environment (e.g., the Docker/Kubernetes pipeline) so the output reflects a neutral environment, or strip these output cells before promoting.

2. Catalog drift: 7 BETA->PRODUCTION entries vs 6 claimed (low)

The PR body lists 6 notebooks promoted, and the title says "promote 6 BETA notebooks." However, the catalog diff contains 7 entries switching from BETA to PRODUCTION. The unlisted 7th entry is a Lean notebook (sous_serie Lean, kernel Python 3 (WSL)) around catalog offset @@ -10157.

The README maturity summary is consistent with 6 net promotions (PRODUCTION 359->365, BETA 105->99), but the raw diff shows 7 -maturity: BETA / +maturity: PRODUCTION flips. This could be a duplicate catalog entry or a legitimate additional promotion that was missed in the PR description. Either way, the PR body should be updated to account for it.

Notes (no action needed)

• All 6 notebooks listed in the PR body were modified consistently (convention prints, intro markdown, re-exec with Papermill).
• Agentic-2-pl_agent.ipynb was modified (convention print + re-exec) but its catalog maturity was not changed -- this is correct since it was already at a non-BETA level.
• Catalog metadata updates (last_validation, issue_pr_associee) look reasonable for the date range.
• No fake/suspicious notebook outputs detected.
