Punch list §25 item 4.3.5d complete. New apic_spi_enable(intid) generalizes item 0.6's PPI-only sequence to one explicit SPI (IPRIORITYR/ISENABLER/ITARGETSR, ICFGR read-checked not written). Verified via a software-pended SPI (GICD_ISPENDR, no device needed) through the existing generic IRQ dispatch, which needed no changes. Found and fixed a real bug during verification: PSTATE.I is still set at apic_init()'s point in boot, so the first self-test run correctly latched but never took the interrupt. Self-test code reverted after capturing evidence -- interrupts.c has zero net diff, only apic_spi_enable() remains, unused until 4.3.5e. Three-arch acceptance boot clean.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
