Real finding, caught before building release on a foundation that
couldn't support it: task 2.2's first cut of sk_hermes_alloc() pulled
reservoir heat but never admitted a real Stadium-floor patron -- just a
local in_use flag. FABRIC-3.5.md SXXXIII.4 item 1 says MSG-FREE-NODE
returns heat "via STADIUM-EVICT", which only means something if
allocation admitted something. SXL.4's own invariant, Sigma(resident
patron heat) + reservoir + consumed == Q48_ONE, cannot balance if held
heat is invisible to every term while held. Flagged to Captain Bob
before proceeding; authorized to correct 2.2 in the same pass as
building 2.3 on top of the fix.
sk_hermes_alloc() now calls stadium_admit() with heat = the pulled
amount, behaviour = STADIUM_BEHAVIOUR_DELIVER (matching messaging.4th's
own SB-DELIVER STADIUM-ADMIT exactly), and identity = the message's own
slot index (matching the FORTH precedent -- caught live in the first
boot of this fix that omitting this made stadium_dispatch()'s existing
DELIVER diagnostic print msg_idx=0 for every message instead of a
distinct value). The returned cell index is stored in the message's
own stadium_cell field. Stadium-floor refusal (independent of reservoir
affordability) rolls back the pull the same way the other refusal
paths already do.
sk_hermes_release() -- the function task 2.3 actually asks for -- calls
stadium_evict() on that cell, which itself returns the departing
patron's remaining heat to its owning VM's reservoir, matching
MSG-FREE-NODE's exact shape. Release does not touch the reservoir
directly.
Self-test (kernel_main.c) extended: keeps every allocated message's
pointer, allocates to exhaustion as before, releases all of them, and
checks the reservoir returns to precisely its starting value.
"Undecayed" is true by construction (no decay/TTL logic exists yet,
task 2.5) -- exact restoration, not approximate.
Three-arch boot clean: amd64/aarch64/riscv64 all reach [zuse@Hera] ok>,
zero UNKNOWN WORD, dict_hash unmoved from task 2.2. All three print
identical PASS arithmetic: reservoir0=65536, reservoir_after_alloc=0,
reservoir_final=65536. No compiler warnings.
stadium_dispatch()'s DELIVER-case console output (one line per
eviction) is pre-existing instrumentation, not new -- confirmed real
and load-bearing per stadium.c's own comment, verbose but expected.
Authorized by Captain Bob ("yes").
