Tasks 1-4 land fully review-green and are the cohesive shippable
subset (the per-thread embedding ABI, fully wired + proven):
- T1: FIXED-FIRST alloc-guard baseline pin (RED captured -> GREEN at T4).
- T2: runtime/rc.c gains ailang_ctx_t {alloc_count,free_count} +
ailang_ctx_new/_free + __thread __ail_tls_ctx; the two increment
sites become 'if (_ctx) _ctx->... else g_rc_...'. g_rc_* statics +
ailang_rc_stats_atexit + the constructor RETAINED VERBATIM as the
null-ctx (single-threaded executable) fallback. rc_accounting_tsan.c
+ driver: per-ctx 8x200000 tsan-clean (de-globalisation positive proof).
- T3: codegen Target::StaticLib forwarder gains a leading 'ptr %ctx'
+ one '@__ail_tls_ctx = external thread_local global ptr' decl +
TLS save/store/restore around the BYTE-UNCHANGED internal call;
_adapter/_clos + internal arg vector untouched (M1 decision held);
doc-comment provisionality narrowed to the value/record layout.
- T4: build_staticlib rejects --alloc != rc (RC-only swarm artefact).
Boss adjudication of the orchestrator's Task-5 BLOCKED (spec-defect,
correctly surfaced not hacked): swarm.c's -DSHARED_CTX negative
control is structurally impossible — examples/embed_backtest_step.ail
is a non-allocating scalar kernel that never writes a ctx field, and
__ail_tls_ctx is __thread, so a shared-ctx scalar swarm has no
shared-memory write to race on (the spec's OWN item-1 honesty point).
The de-globalisation teeth belong to the item-1 rc_accounting harness
(shared ctx genuinely races on ctx->alloc_count; orchestrator
independently confirmed tsan exit 66). Spec amended in lockstep
(Goal coherent-stop, must-fail-axis item 2, Testing item 3,
Acceptance) so item 3's negative control is item-1's by the
de-globalisation-proof / capability-demo split; plan Task 5
restructured (swarm.c per-ctx capability demo only; negative-control
standing test relocated into the item-1 harness driver) + Task 3's
plan-transcription error (@ail_backtest_step ->
@ail_embed_backtest_step_step) corrected. This is a Boss
consistency-repair of an internally-contradictory clause whose intent
is already correctly realised in the same spec — not a redesign; no
brainstorm bounce. Task-5 working files discarded (corrected plan
reproduces them; a structurally-RED test must not enter main).
INDEX.md + final journal land at iter completion (re-dispatch [5,9]).
