git.stella-ops.org/docs/modules/scanner/operations/entrypoint-lang-phpfpm.md
master e8537460a3 feat(docs): Add comprehensive documentation for Vexer, Vulnerability Explorer, and Zastava modules 
- Introduced AGENTS.md, README.md, TASKS.md, and implementation_plan.md for Vexer, detailing mission, responsibilities, key components, and operational notes.
- Established similar documentation structure for Vulnerability Explorer and Zastava modules, including their respective workflows, integrations, and observability notes.
- Created risk scoring profiles documentation outlining the core workflow, factor model, governance, and deliverables.
- Ensured all modules adhere to the Aggregation-Only Contract and maintain determinism and provenance in outputs.

Entry-Point Runtime — PHP-FPM

Signals to gather

  • argv0 equals php-fpm or php-fpm8* variants; master process often invoked with -F or --nodaemonize.
  • Configuration files: /usr/local/etc/php-fpm.conf, www.conf, pool definitions under php-fpm.d.
  • PHP runtime artefacts: composer.json, public/index.php, artisan, wp-config.php.
  • Environment variables such as PHP_FPM_CONFIG, PHP_INI_DIR, APP_ENV.
  • Socket or port exposure (listen = 9000, /run/php-fpm.sock).

Implementation notes

  • Verify master process vs worker processes (master stays PID 1, workers forked).
  • Inspect pool configuration to extract listening endpoint and process manager mode.
  • If docker-php-entrypoint is involved, ShellFlow must expand to php-fpm.
  • Distinguish FPM from CLI invocations (php script.php) to avoid misclassification.

Evidence & scoring

  • Reward confirmed config files and listening sockets.
  • Add evidence for application artefacts (Composer lockfile, framework directories).
  • Penalise when only the binary is present without config (could be CLI usage).

Edge cases

  • Images bundling Apache/Nginx front-ends should end up as Supervisor with PHP-FPM as a child service.
  • Some Alpine packages install php-fpm7 naming—include aliases in detector.
  • When php-fpm is launched via s6 or supervisor, rely on child detection to avoid double counting.
