goal
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:cf943417270f2863
(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.

THE SAME MODULE ALSO LIVES AT THESE FORGE TIPS: none — this module is unique to
artifact_tree_gen among the repos scanned so far.
HISTORICAL OCCURRENCES of this exact blob — every 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. Context for the
rewrite, not extra work:

THE CALLABLE SURFACE — every callable in the original, lowered with codebean's
`lower_node` (#183). The rewrite must present THIS surface (same names, same
parameters, same defaults) so callers of the original keep working:
clamp(x, lo, hi)
CAPTURED BEHAVIORAL EXEMPLARS — real (input, output) pairs mined from THIS module
with criteria_miner (#200's "verified, not asserted"), running the ORIGINAL as the
oracle. THE REWRITE MUST REPRODUCE EVERY PAIR BELOW, exactly:
clamp(x, lo, hi) — 24 exemplar(s) captured:
clamp(0, 0, 0) == 0
clamp(0, 0, 1) == 0
clamp(0, 0, -1) == 0
clamp(0, 0, 1.5) == 0
clamp(0, 0, True) == 0
clamp(0, 1, 0) == 1
... 18 more exemplar(s) for this function — re-mine them with
criteria_miner.mine() on the source above
HONEST LIMIT (criteria_miner's own): these cover the SAMPLED inputs, probed
around the function's own branch constants. They are a strong refactor-drift net,
NOT a proof of total equivalence — so treat them as the FLOOR of this ticket's
equivalence evidence and add the edge cases they miss (see ACCEPTANCE).
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.
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.
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.
