From c9a84b33b3e7806491153a5bd3037be1b8ef9d31 Mon Sep 17 00:00:00 2001 From: Brummel Date: Mon, 18 May 2026 17:16:40 +0200 Subject: [PATCH] iter embedding-abi-m2.1 (PARTIAL 4/9 + Boss spec-defect repair): ctx ABI + de-globalisation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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).

The forwarder's TLS transport uses +`@__ail_tls_ctx`, a `__thread` global — per-thread storage that is +never shared across threads even when the `ailang_ctx_t*` value is +passed to a shared ctx. There is therefore no shared-memory write to +race on. `swarm_neg` runs clean, exits 0, prints `swarm: ok (3500000)`. +This is structural: the chosen M2 scalar kernel cannot exhibit the +asserted behaviour. The implementer-faithful diff is correct; the +plan's premise for this one test is wrong. The real +de-globalisation race surface (concurrent `ctx->alloc_count++`) is the +rc primitives, which `swarm.c` never calls directly — that surface IS +covered with teeth by Task 2's `rc_accounting_tsan.c -DSHARED_CTX` +(independently confirmed to race at `rc.c` in `ailang_rc_alloc`, +tsan exit 66). Weakening the swarm negative control to make it pass +is forbidden (voids the coherent-stop proof; Boss constraint 8). +Suggested next step: Boss decision — either (a) drop +`shared_ctx_negative_control_is_flagged_by_tsan` from Task 5 (the +de-globalisation negative control is Task 2's job by the plan's own +"distinct spec role" split; swarm.c is the capability demo only — +keep only the per-ctx positive test, which passes), or (b) re-spec +Task 5's negative control to exercise an *allocating* exported kernel +so the shared ctx genuinely races (requires a new fixture + spec +amendment via brainstorm, since M2's scope is scalar-only).
