fix(lint): convert #8269's bare handle reads to with_* forms — unbreaks pr-gate on main

[proggeramlug]

Unbreaks the required lint context on main — red since #8269 merged this morning, which reds pr-gate on every rebased PR (found via #8244's run; verified on a clean main checkout).

Cause: #8269's native_module_enum is correctly rooted (RuntimeHandleScope, per-iteration scopes) but reads its handles through bare get_raw_*_ptr — 9 new sites, pushing object/field_get_set/enumeration.rs to 14 against its per-module ceiling of 5 in the raw-handle debt ratchet.

Fix: convert all nine to the #7341 blessed with_{mut,const}_ptr argument-position forms. Behaviorally identical by definition (with_mut_ptr(f) = f(self.get_raw_mut_ptr()) — a scoped re-read from the handle at each call site); no rooting or ordering change. Also ratchets the global baseline down 990 → 983 per the audit's own "debt fell, lock it in" prompt — locking in unrelated drops in builtins/globals.rs (15→12) and global_this_webassembly.rs (9→5) that had landed without an update.

Validation: raw_handle_debt.py green (983/983, 109 modules within ceilings); cargo check -p perry-runtime clean; full cargo test -p perry-runtime --lib (RUST_TEST_THREADS=1) result posted below when it completes; cargo fmt applied.

📝 Walkthrough

Walkthrough

The enumeration implementation now uses scoped pointer closures for rooted array access. The changelog and raw-handle debt tracking files record the nine conversions and reduced debt thresholds.

Changes

Enumeration raw-handle cleanup

Layer / File(s)	Summary
Scoped enumeration pointer access crates/perry-runtime/src/object/field_get_set/enumeration.rs	native_module_enum uses with_const_ptr and with_mut_ptr for rooted key, result, and pair arrays.
Raw-handle debt tracking updates changelog.d/8288-enumeration-raw-handle-debt.md, scripts/raw_handle_debt_baseline.txt, scripts/raw_handle_debt_files.txt	The changelog records the conversions. The global baseline changes from 990 to 983. Two module ceilings are reduced.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 77f95

The runtime fix is localized and mergeable, but the changelog fragment uses PR #8288 instead of PR #8291, which could misattribute the release note; rename the file as follow-up.

Merging immediately — this unbreaks the required lint context on main, and the breakage is mine.

Confirmed on a clean main checkout: raw_handle_debt reports 992 bare reads against a baseline of 990. With this PR: 983 against 983. Nine sites converted, baseline re-pinned to lock the improvement in.

The cause is exactly as you diagnosed: #8269, which I merged earlier today. Its native_module_enum is correctly rooted — RuntimeHandleScope, per-iteration scopes, re-reads after every collection point — but it reaches its handles through bare get_raw_*_ptr, which is what the #7341 ratchet counts. Nine new sites took object/field_get_set/enumeration.rs to 14 against a per-module ceiling of 5. I ran the census, thread-locals, addr-class and file-size gates on #8269 and did not run this one.

That is the fourth gate I have broken today the same way — gc_runtime_root_holders after #8270, -D warnings after #8294, api-docs-drift after #8279, and now this. Same pattern each time: I ran the subset of gates that looked topically relevant instead of the whole set. The correction is mechanical and I have been applying it since; recording the count here so it is visible rather than spread across four PRs.

Converting to with_{mut,const}_ptr is the right fix rather than raising the ceiling. The argument-position forms never bind the pre-call address, so the ordering is expressed in the call itself — that is the property the ratchet exists to push toward, and re-pinning the baseline downward is what turns the fix into a ratchet rather than a reprieve.

Verified here: runtime 2571/0/4, raw_handle_debt 983/983, plus unrooted_local_shape --check, gc_runtime_root_holders, check_thread_locals, addr_class_inventory and cargo fmt all clean.
