# OBSOLETE/ACTIVE ENV Cleanup Plan (file-by-file)

## Summary
- Baseline: **221** ENV variables from the initial sweep (Nov 26); current recount (includes `.inc` helpers) shows **~279** unique getenv names.
- Box boundaries: move getenv calls to init boundaries where possible; keep hot paths free of repeated getenvs.
- Active & non-removable: **Ultra**, **BG**, **HeapV2/FrontV2**, **SFC**, **Thread Cache**, **Ring (L25)** — all are compiled and used; only A/B gating allowed.
- Docs-only: **21** proposal-only variables have zero getenv hits (see `SAFE_TO_DELETE_ENV_VARS.md`) and can be dropped from docs with no rollback risk.
- Goal: reduce production-facing ENV surface without breaking rollback; keep debug knobs behind a single boundary per box.

## Priorities
1. **SFC_DEBUG consolidation** (Box boundary): single init-time getenv in `core/hakmem_tiny_sfc.c`, reuse `g_sfc_debug` in `core/tiny_alloc_fast_sfc.inc.h`, `core/tiny_free_fast.inc.h`, `core/box/hak_wrappers.inc.h`.
2. **Doc hygiene**: remove the 21 docs-only names from `docs/specs/ENV_VARS*.md`; keep a short changelog entry noting they never existed in runtime code.
3. **Debug gating**: corral *_DEBUG/_TRACE/_STATS getenvs into debug-only paths or init-time caches (avoid hot-path getenv per call).
4. **Verification guardrails**: keep Ultra/BG/HeapV2 toggles intact; any deprecation must be #ifdef/A-B gated with a rollback env.

## Feature Decisions (keep vs. change)
- **KEEP (active)**: Ultra (`core/box/ultra_slim_alloc_box.h`), BG (`core/hakmem_batch.c`, `core/hakmem_l25_pool.c`), HeapV2/FrontV2 (`core/front/tiny_heap_v2.h`, `core/tiny_alloc_fast.inc.h`), SFC (`core/hakmem_tiny_sfc.c`), TC/Ring (`core/hakmem_l25_pool.c`, `core/box/pool_init_api.inc.h`).
- **CLEAN**: Duplicate `HAKMEM_SFC_DEBUG` getenvs; legacy doc-only set (21 vars) from specs/papers.
- **REMOVED (commit 6b791b97d, 2025-11-26)**: 6 Ultra/BG ENV vars:
  - `HAKMEM_TINY_ULTRA_FRONT`
  - `HAKMEM_TINY_ULTRA_L0`
  - `HAKMEM_TINY_ULTRA_HEAP_DUMP`
  - `HAKMEM_TINY_ULTRA_PAGE_DUMP`
  - `HAKMEM_TINY_BG_REMOTE`
  - `HAKMEM_TINY_BG_REMOTE_BATCH`
- **DEFER**: Any removal of remaining Ultra/HeapV2/BG toggles until explicit user approval; these are part of the active Box stack.

## File-by-File Checkpoints (actionable)
- **SFC (Shared Frontend Cache)**
  - `core/hakmem_tiny_sfc.c:51,62,71,123,144` — keep enable/capacity/refill/debug/stats; cache `HAKMEM_SFC_DEBUG` here.
  - `core/tiny_alloc_fast_sfc.inc.h:114`, `core/tiny_free_fast.inc.h:104`, `core/box/hak_wrappers.inc.h:89` — switch to cached `g_sfc_debug`.
  - `core/tiny_alloc_fast.inc.h:477` — `HAKMEM_SFC_CASCADE_PCT` stays feature-tunable.
- **BG system**
  - `core/hakmem_batch.c:73` (`HAKMEM_BATCH_BG`) — active default; keep.
  - `core/hakmem_l25_pool.c:741-743` (`HAKMEM_L25_BG_DRAIN`, `HAKMEM_L25_BG_MS`) — keep; optionally cache at init.
- **HeapV2/FrontV2**
  - `core/front/tiny_heap_v2.h:45,58,87,119` — class mask/leftover/debug toggles; keep A/B path.
  - `core/tiny_alloc_fast.inc.h:167,352` and `core/hakmem_tiny.c:578` — stats/enable toggles; keep.
  - `core/box/front_metrics_box.*` — metrics/dump toggles; keep.
- **Ultra**
  - `core/box/ultra_slim_alloc_box.h:87,226`, `core/box/hak_core_init.inc.h:279` — keep experimental toggles; require #ifdef rollback if changed.
  - **Removed in commit 6b791b97d**: `HAKMEM_TINY_ULTRA_FRONT`, `HAKMEM_TINY_ULTRA_L0`, `HAKMEM_TINY_ULTRA_HEAP_DUMP`, `HAKMEM_TINY_ULTRA_PAGE_DUMP` (files deleted: `core/front/tiny_ultrafront.h`, `core/ultra/tiny_ultra_heap.c`, `core/ultra/tiny_ultra_page_arena.c`).
- **Ring/TC**
  - `core/hakmem_l25_pool.c:718,724,745`, `core/box/pool_init_api.inc.h:60,66` — ring controls (active).
  - `core/hakmem_l25_pool.c:737,739`, `core/box/pool_init_api.inc.h:72-78` — TC controls (active); no removal.
  - `core/tiny_debug_ring.c:195,231` — debug-only; gate behind build/debug.
- **Doc-only cleanups**
  - Remove mentions of the 21 docs-only names (see `SAFE_TO_DELETE_ENV_VARS.md`) from `docs/specs/ENV_VARS.md` and `docs/specs/ENV_VARS_COMPLETE.md` when touched; no code changes required.

## Debug/Stats Gating Guidance
- Collapse hot-path debug getenvs into init-time caches (`static int g_* = -1;` pattern) to honor Fail-Fast without repeated getenv.
- Keep production surface small: gate *_DEBUG/_TRACE/_DUMP behind `HAKMEM_BUILD_RELEASE` or init-time knobs in `hak_core_init.inc.h`.
- Prefer one-shot logging (Box Principle #4) rather than repeated tracing in hot paths.

## Verification Notes
- Ultra/BG/HeapV2 toggles are **active**; treat any deletion as a feature-removal project with A/B fallback (`HAKMEM_TINY_ULTRA_DEBUG`, `HAKMEM_BATCH_BG`, `HAKMEM_TINY_HEAP_V2_*`).
- Doc-only list was confirmed with `rg` diff (`comm -23 docs_env code_env`); zero getenv hits.
- Count drift (221 → ~279) comes from `.inc` helpers now included in the scan; keep 221 as the baseline metric but track the expanded map below.

## Completed in this session (release gating of debug env)
- Disabled getenv for debug/trace in release builds: `HAKMEM_TINY_TRACE_RING`, `HAKMEM_TINY_DUMP_RING_ATEXIT`, `HAKMEM_TINY_RF_TRACE`, `HAKMEM_TINY_MAILBOX_TRACE(_LIMIT/_SLOWDISC/_PERIOD)`, `HAKMEM_SS_PREWARM_DEBUG`, `HAKMEM_SS_FREE_DEBUG`, `HAKMEM_TINY_FRONT_METRICS`, `HAKMEM_TINY_FRONT_DUMP`, `HAKMEM_TINY_COUNTERS_DUMP`, `HAKMEM_TINY_REFILL_DUMP`, `HAKMEM_PTR_TRACE_DUMP`, `HAKMEM_PTR_TRACE_VERBOSE`.
- SFC_DEBUG getenv consolidated to init boundary (`g_sfc_debug`).
