For the case you lost the 6.3.0 code (AI reconstruction) - #1520

…d (6.3.0_inference)

Condensed from 9 commits (0ee8492..02328a0):
- 6.2.1 and 6.2.2 official-image source transfers (web/frontend, services, tools,
  scripts, settings defaults, i18n, tests, docs, package manifests) incl.
  flush_docs_with_pending_updates.js added in 6.2.2
- 6.3.0 source sync from the official image (1421 changed / 556 added / 155 deleted,
  byte-verified) with server-ce/Dockerfile + Dockerfile-base aligned to the official
  build recipe (Node 24 nodesource, corepack Yarn 4.18.0 PnP, install/compile mounts)
- Build fixes: NODE_OPTIONS via quoted legacy ENV (Docker 29 JSON-array form mangles
  multi-word values); 3 codemirror git-dep zips pre-staged in .yarn/cache (avoids
  Yarn-Classic pack race under buildkit; identical to official image); stale 6.2.x
  floating-menu-setting files removed; babel .cache kept out of the image via cache mount

Verified: container-diff vs docker.io/sharelatex/sharelatex:6.3.0 → history parity
None/None, apt/pip only noble point-release version bumps, file residuals only
build-date/machine-hash noise (rosetta, node-compile-cache, install-state.gz);
live on shared overleafserver (migrations OK, all services up, /login 200).

- NODE_OPTIONS must repeat the PnP loader (--require .pnp.cjs --import
  .pnp.register.mjs) on top of --inspect, because compose environment entries
  override the image ENV wholesale and the PnP hook is what resolves all
  workspace modules.
- webpack: npx -> yarn exec (PnP image has no node_modules/.bin).
- mongo:8 -> 8.3, redis:7 -> 8.6-alpine, GLIBC_TUNABLES=-SHSTK for 8.x mongod
  on hosts advertising the SHSTK CPU feature.
- bin/dev: docker-compose -> docker compose (standalone binary was removed
  upstream; only the compose plugin is shipped).
- bin/logs: keep ggrep/bunyan pipeline when present, tolerate their absence
  with a plain grep fallback.
- restore bin/shared/mongodb-init-replica-set.js (still mounted into mongo
  for replica-set init; accidentally dropped during the transfer).
