Ticket graphs

Rewrite ONE unique forge module as entirely new, behavior-preserving, installable, control-config'd Python, per the FORGE-wide refactor standard #200 (#std). This ticket covers ONE module — the one identified below — and nothing else. It was filed against the module's DEDUPLICATED identity, so if that module was copy-pasted across the forge, every copy is covered by this single ticket. MODULE KEY : forge-rw:1fa0fdbc322b6466 (the ticketer's idempotency marker — it lives in this ticket's TITLE. Do not edit the title, or the module will be re-filed as a duplicate.) IDENTITY : AST-NORMALIZED — codebean's `_ast_norm` (#183), i.e. ast.dump(ast.parse(ast.unparse(ast.parse(src)))). Copies of this module that differ only in comments, blank lines, quoting or spacing carry the SAME module-sha and are covered by THIS ticket. A differing docstring is real content, so a module whose docstring differs is a DIFFERENT module with its own ticket. SIZE : 3464 bytes EXTENSION : .py CANONICAL SOURCE (the location this ticket is named for): repo : agent_tools_suite path : ats_service.py ref : HEAD (HEAD) blob : c7947a7e56c83c810b72ca13279c35431b762745 (git blob sha1) REFERENCE ONLY — you do NOT need this command. This module's bytes are embedded COMPLETE in THE ORIGINAL SOURCE block below, and that is what the rewrite is based on. For a reader who does have forge access: git --git-dir=/Users/stevenpeterson/code/installed/jazz-project/config/forge/remotes/agent_tools_suite.git cat-file blob c7947a7e56c83c810b72ca13279c35431b762745 THE SAME MODULE ALSO LIVES AT THESE FORGE TIPS: none — this module is unique to agent_tools_suite among the repos scanned so far. HISTORICAL OCCURRENCES of this exact blob — every OTHER DISTINCT {repo, path} the omni-git index (`occ`, joined on the git blob sha1) records this byte-identical file at, with the index's own `ts` for the first row of each. Any place this run enumerated LIVE is listed under the forge tips above, not here. Context for the rewrite, not extra work: testmonkeyalpha-group/jazz-forge/agent_tools_suite:ats_service.py [occ.ts gitlab] THE ORIGINAL SOURCE, EMBEDDED — YOU NEED NO FORGE ACCESS TO DO THIS TICKET. The module's own bytes are reproduced below, inside this ticket. THEY are the authoritative copy and the behavior-preserving basis: rewrite from them. The `git --git-dir=... cat-file blob` command under CANONICAL SOURCE above is kept only as a REFERENCE for a reader who happens to have forge access — running it is NOT part of this ticket. (Why the bytes are here at all: the pair_loop worker that executes this ticket is sandboxed to the ticket's own congruency worktree and cannot read the forge's bare repos. Ticket #346 is the fix that put them on the ticket.) The block BEGINS at the line ===ORIGINAL SOURCE (verbatim, the behavior-preserving basis)=== and ENDS at the first line ===END SOURCE=== Everything strictly between those two lines is the module — 3464 byte(s), byte for byte, with no re-indentation, no re-wrapping and nothing elided. ===ORIGINAL SOURCE (verbatim, the behavior-preserving basis)=== #!/usr/bin/env python3 """ats_service — start/stop the ats gate as a plain user process, at your discretion. python3 ats_service.py on # start the gate in the background python3 ats_service.py off # stop it python3 ats_service.py status # running? serving? auth enforced?

The rewrite must present THIS surface (same names, same parameters, same defaults) so callers of the original keep working: read_pid() endpoint_status() on() off() status() main() CAPTURED BEHAVIORAL EXEMPLARS: none. no function in this module is minable — criteria_miner mines only self-contained pure functions (it refuses anything that mentions a world-touching or non-deterministic name, plus methods and no-arg functions), and nothing here qualified This does NOT weaken the ticket's bar — it MOVES the work: you must write the equivalence exemplars by hand from the original's behavior before rewriting, and they are what settles this ticket. THE STANDARD — #200's four requirements, which this ticket exists to enforce. All four are the standard's own words; none is optional: 1. BEHAVIOR-PRESERVING, VERIFIED NOT ASSERTED — the deliverable is ENTIRELY NEW source code (rewritten, not copied). It must reproduce the ORIGINAL's behavior, and the proof is the exemplars above (captured via codebean lower_* #183 + criteria_miner IO-exemplars, exactly as #200 specifies). 2. A PYTHON MODULE — regardless of the source language. This module's source is `.py`; the rewrite is Python either way. 3. INSTALLABLE — a proper package: pyproject.toml, `pip install -e .` works, console entry points where applicable. WRITE ONLY YOUR OWN MODULE FILE at forge2/<repo>/<module>.py. Do NOT hand-author pyproject.toml or __init__.py: the harness DERIVES them ADDITIVELY from the modules present (congruency/tools/ forge_package.py, #410 — the analogue of the tag-registry fix #281), so your unit never conflicts with, or clobbers, a sibling module of the same forge2/<repo>/ package. A package-level pyproject includes every .py in the directory, so your module installs and imports as `<repo>.<module>` the moment it lands. 4. CONTROL-CONFIG'D — NO hardcoded paths or params. A JSON/registry config object drives it (the install.json / registry.json idiom of this repo), and per note-for-claude a tool that cannot see its config THROWS rather than guessing a default. Add ONLY your own `forge2.<repo>.<module>` section to the package's registry.json (create the file if it is absent); NEVER read, edit or drop a sibling module's section — the sections are disjoint keys and stay additive that way. ACCEPTANCE (#200's, per rewrite ticket) — this ticket settles when ALL of: a. the new source reproduces every captured exemplar above, plus the edge cases you add for what sampling cannot reach (paste the runs as evidence); b. it presents the callable surface above, so existing callers keep working; c. `pip install -e .` installs it clean from its own pyproject.toml; d. it runs off a config object with ZERO hardcoded settings, and throws without one. Kind is `build` (a pair: coder + adversarial tester). This ticket hangs off #200 by a `spawned` edge, so a stop ticket aimed at #200 brakes every rewrite in this programme. Filed mechanically by checkouts/current/congruency/tools/forge_refactor_ticketer.py under ticket #201, from the forge bare repos at /Users/stevenpeterson/code/installed/jazz-project/config/forge/remotes. Its original source is embedded above (#346), so this ticket is complete on its own.
