## [Unreleased]

## [0.34.0] - 2026-07-08

**Multi-table call_indirect ships (falcon's fused-component blocker); float
and i64 global initializers actually reach the image; the mask bounds mode
becomes sound. Six gale filings closed same-day across two waves.**

### Added

- **Multi-table call_indirect (#650, PR #653).** Tables form one contiguous
region at R11 (table N at a compile-time constant offset — sound because
tables are provably fixed-size per #646); the dispatch folds the offset
via R12; the #642 bounds guard checks the dispatched table's own size and
the closed-world type verification runs per (table, expected-type).
Single-table modules are byte-identical BY CONSTRUCTION (offset-0 emits
the literal pre-#650 sequence — verified by whole-ELF cmp across three
targets). New CI oracle: two-table aliasing canary + per-table OOB traps,
26/26 (both ISAs).

### Fixed

- **Global initializers never reached the self-contained image (#649,
PR #652; float side GI-FPU-001, PR #648).** The decoder only captured
i32.const inits, and the default Cortex-M image never materialized the
globals table at all — R9 was uninitialized and reads returned
vector-table garbage. Now the startup stub sets R9 and stores every init
word (width-aware #645 layout, i64 = two words); float-typed globals
loud-skip (GI-FPU-001). New oracle executes the image's real reset path
in unicorn: 4 divergences → 0. Sibling filed: #655 (RV32 mask-order twin).
- **--safety-bounds mask applied the mask before the static offset (#651,
PR #654)** — the offset escaped the bound; AND the old mask used the
memory SIZE (not size-1), remapping in-bounds accesses to 0. All 8 mask
sites now share one helper: min((operand + offset) & (size-1),
size - access_size), with the u33-soundness argument documented and
large offsets materialized (no decline). Mini-interpreter oracle: 8/8
FAIL → 8/8 ok. Non-power-of-two memories decline loudly under mask.
