# 009 — Remaining path to AXP / Graphene-class ship (post clean-429)

Non-normative roadmap after LAB **BOOT_OK** on Stage1+combo4+FORTIFY+Magisk+
**CVE clean-offset 429** (denylist `CVE-2022-49980`), kernel `#47`
(`20261001T180955Z-axp-stage1-combo4-cve-clean`). Authoritative requirements
remain `specs/009-axp-los23-port/spec.md` + constitution.

Goal (owner): **almost all** applicable AXP.OS / Graphene-class behaviour on
LOS 23.2 sunfish Magisk track — not a blind dump, not bootloader lock.

## Already landed (kernel / Magisk core)

| Layer | Status |
|-------|--------|
| Stage1 Graphene/AH | Ship |
| Combo4 + Clang FORTIFY | Ship |
| Magisk preroot EXTENDROM-class | Ship |
| CVE clean-offset 429 | Ship (LAB OK) |
| `CVE-2022-49980` | Denylist until lock-scope port |
| High-offset CVE (~73) | Quarantine — triage started |

Recover/bisect baseline: `20260929T123401Z-axp-stage1-combo4` (`#32`).

## Kernel remaining (toward “AXP CVE / Graphene depth”)

1. **High-offset quarantine** — KEEP batches 1–3 **shipped** (`151944Z`).
   nf_tables leftovers still skipped. Next kernel depth: **US-S5-1** defconfig
   (Yama + `SLAB_FREELIST_RANDOM`), not more bulk CVE.
2. **`CVE-2022-49980` proper port** — keep UAF fix without recursive
   `udc_lock` (mainline lock-scope series). Optional; denylist is safe.
3. Failed Stage1 probes (allocsize/ro/slab) — low priority vs high-offset.
4. Graphene modern techniques / `hardened_malloc` — backlog (`docs/hardening-backlog.md`);
   evaluate after CVE depth is stable.

## Userspace / product remaining (AXP surface)

From `docs/009-capability-matrix.md` / Gate G (still open or partial):

| Item | Notes |
|------|--------|
| Release keys + AVB (unlocked) | US-S2/S3 — leave test-keys |
| Private DNS / connectivity check | Patches exist; keep AXP-class, no axp.os endpoints |
| Call-rec / FLAG_SECURE | `008` — selectable unlock |
| Bundled apps (Aurora, Droidify, gallery, …) | Packaging |
| Disable-app UX on A16 | Restore classic Disable |
| Hosts / DNS privacy helpers | Magisk module vs ROM-native TBD |
| WebView | LOS default (Aosmium exception) |
| Banking / Island | Deferred |
| Bootloader lock | Wont |
| KernelSU swap | Optional later; do not mix Magisk ship boots |

## Suggested execution order (default if owner has no preference)

1. Finish high-offset **relevance filter** → small apply batches (≤10) with
   strict applicator + LAB boot each batch.
2. Wire **release keys** bacon of current ship pack; keep Magisk/preroot OK.
3. Land remaining **Settings/UX** AXP clones (DNS, connectivity, disable-app)
   if not already on LAB zip.
4. Optional: 49980 lock-scope port; Graphene userspace / hardened_malloc spikes.

## Do-not

- Reflash full-503 / old kh-cve zips.
- Bulk-apply high-offset without manual review.
- Mix KernelSU into Magisk ship boots.
- Treat “almost AXP/Graphene” as requiring locked bootloader.
