The 117 bundled patch identifiers had grown five naming schemes
(kernel.x, jb.x, kernelcache_jb.x, txm_dev.x, bare names). Each one is now
{component}-{effect}-{name}:
- component: avpbooter, ibss, ibec, llb, txm, kernel, devicetree, dyld,
preboot, or system-<binary> for a guest binary or file.
- effect: boot when the patch is boot-essential, exp when the standard
preset leaves it off, cfw otherwise. A catalog test enforces this.
- name: snake_case, no hyphen, so the identifier splits from the right.
Record sites are now always <identifier>.<site>. The underscore-prefix
rule in covers(recordIdentifier:) and in the gate is gone: the new names
contain underscores, so kernel-boot-post_validation would otherwise have
covered kernel-boot-post_validation_unsigned. The 25 records that relied
on it (amfi_trustcache_1, launch_constraints_mov, sandbox_ext_N, ...) now
use a dot.
Old identifiers are not migrated. A VM whose PatchPlan or PatchSelection
names one must be patched again. The bundle becomes 2.2.0 and Launchpad
requires 2.2.0, so it never meets an old identifier from a bundle.
Launchpad's patch table shows Component, Effect and Name columns in place
of Identifier and Patch Set; the set moves to the detail line.
