Lyger v0.2 validation results

These measurements were executed locally on 2026-07-21 using PHP 8.3.30 and the updated Rust library in libraries/libs.

Static checks

php -l over Lyger, App, routes, and database: all files passed.
composer validate --no-check-publish: passed.
Composer authoritative autoload generation: passed without warnings.

Framework benchmark (`benchmark/run.php`)

One run completed with exit code 0:

Test	Measured result
Hello World loop (1,000 iterations)	0.01 ms / 123,361,882 loop iterations/s
Heavy computation (10M iterations)	PHP 368 ms; Rust FFI 73 ms; measured ratio 5.1x
JSON serialization (1,000 objects × 100)	PHP 20.59 ms; reported Rust estimate 6.86 ms
SQLite FFI query + JSON	1.68 ms
Memory allocation sample	16 MB used; 18 MB peak

The benchmark’s JSON Rust value is currently a calculated estimate ($phpTime / 3), not a Rust execution measurement. The Hello World loop is also a PHP in-process loop, not HTTP throughput. These values must not be presented as end-to-end framework or network benchmarks until dedicated reproducible harnesses are added.

Database services

PostgreSQL and MySQL containers are defined in the repository-level docker-servers/ compose file. Rust-core integration tests against both services passed separately; PHP driver parity remains a framework gap.

Two-track validation

The framework is validated in two independent contexts:

v0.2/tests/: framework contracts and HTTP E2E.
Dental_Clinic/tests/: the real consumer application using the same v0.2 libraries.

Both contexts pass PHP lint, Composer autoload generation, database, health, streaming and HTTP contracts when their local server is running.

The Rust PHP driver contract now passes through the actual FFI library for all three environments:

v0.2 → SQLite: PASS
v0.2 → PostgreSQL 15: PASS
v0.2 → MySQL 8.0: PASS
Dental Clinic → SQLite: PASS
Dental Clinic → PostgreSQL 15: PASS
Dental Clinic → MySQL 8.0: PASS

QueryBuilder still defaults to its legacy PDO implementation; the new DatabaseManager/RustDatabaseDriver path is validated independently and must be made the configured default before claiming full ORM Rust-driver parity.

v0.2 streaming validation

Using the ARM64 library from v0.2/libraries/libs/Mac/:

v0.2 streaming contract: PASS
Dental Clinic streaming contract: PASS
Result chunks preserve ordering and are bounded to the requested page size.
memoryMetrics() returns used_bytes and budget_bytes.
Handles are released in finally blocks after consumption.

Installer validation

The installer was executed in isolated temporary copies (the source tree was not modified):

Vue.js selector: PASS
React selector: PASS
Svelte selector: PASS
core:download-binaries verifies the platform artifact: PASS
Generated frontend template and .lyger_installed marker: PASS

Always-Alive HTTP status

The first attempt timed out because PHP encoded empty headers as [], while Rust requires a JSON object. After normalizing headers to (object), local curl validation passed: /api/health returned 200 and /missing returned 404 with JSON body. The same checks passed in Dental_Clinic after synchronizing v0.2.
