Changelog: 0.7.4-beta.29

What's new in 0.7.4-beta.29

Bug Fixes

• Plugin unload cleanup — verbs and qualifiers are now properly deregistered when a plugin is unloaded, preventing stale handler registrations (Test framework: --generate doesn't create __TIMESTAMP__ placeholders #153)
• Global symbol eviction — GlobalSymbolStorage entries are now evicted when their owning execution ends, fixing a memory leak in long-running applications (Binary execution: RepositoryObserver returns generic responses instead of executing handlers #155)
• Binary mode stack overflow — expression evaluation in compiled binaries is now guarded against stack overflow; the NSThread stack size is increased to 8 MB and several missing action bridges have been added
• Linux build — fixed build errors in withStackGuard that prevented compilation on Linux
• OpenAPI $ref in parameters — parameter definitions that use $ref are now resolved correctly, so referenced schemas work in path/query parameters
• Plugin loader — fixed several plugin loader bugs; Rust plugins are now auto-compiled on load and embedded into the binary when running aro build (Plugin not loaded from compiled binary when .so is in plugin root directory #255)
• Rust plugin self-copy — skip redundant self-copy in compileRustPlugin when source and output directories are the same
• ResponseHeaders example — made self-contained so it no longer depends on an external API that could cause test flakiness
• Docs / training-data quality — corrected ARO syntax errors across the Book, Proposals, and MCP documentation

Refactoring

• Extractable protocol — replaced repetitive cast chains in the Extract action with a new Extractable protocol, making it easier to add support for new types
• TOCTOU elimination — RepositoryStorageActor no longer has a time-of-check/time-of-use race; reads and writes are now fully serialised through the actor

Performance

• Activity dispatch index — the runtime now builds a businessActivity → [FeatureSet] index at load time instead of scanning on every event, cutting dispatch overhead for applications with many feature sets (Fix: Remove debug output from binary builds #158)
• Lazy plugin loading — plugins are loaded on first use rather than eagerly at startup, reducing cold-start time (Fix: Display array contents in console output #157)
• Template parse cache — parsed templates are cached and keyed by file modification time, so repeated renders of the same template skip re-parsing (fix: eliminate all compiler warnings #160)

Architecture

• RuntimeContainer — introduced a lightweight DI container (RuntimeContainer) so services and actions can declare dependencies declaratively rather than reaching into global singletons (Native compilation ignores when clause conditions #156)
