# runtime loads (the @napi-rs/canvas Skia renderer, @node-rs/argon2, the

# build needs ARMv8.2 (LSE atomics, RCpc loads) and dies with SIGILL on an
# ARMv8.0 core such as the Raspberry Pi 4's Cortex-A72; the glibc arm64
# build does not use those instructions (#1311). trixie over bookworm: on
# the day of the switch the bookworm-slim base carried a CRITICAL finding
# (zlib, marked will-not-fix) that trixie-slim does not.

# v1.4.43 B11 — version build-arg threaded into the layer cache key.
# Pre-v1.4.43 the docker-publish workflow shipped a stale package.json
# version baked into the bundle because BuildKit reused the `pnpm build`
# layer across releases (the COPY . . layer key was content-stable when
# only the version string had changed and the next pnpm install layer
# was warm). Passing the tag as a build-arg forces a per-release cache
# miss on this layer and forwards the value into the runtime env so
# /api/version reads from $NEXT_PUBLIC_APP_VERSION first.

# (docs/ops/deploy.md). The built-at timestamp is intentionally NOT
# set in this stage: it differs on every run and would bust the

# copy in the store and the file tracer packed it whole. Bumping the adapter to
# 7.10.0 moved its transitive pg to 8.23.0 while ours stayed at 8.22.0. The
# tracer then packed only the copy the adapter reached, the top-level link
# pointed at the other one, and this line failed with "Cannot find module

# resolutions must work: (1) pdfjs-dist does a bare `require('@napi-rs/canvas')`
# from its OWN dir — Node walks up to /app/node_modules, so the package must be
# HOISTED to the top level there (verified: without it pdfjs logs "Cannot load
# @napi-rs/canvas" → "Cannot polyfill DOMMatrix" → rasterize ReferenceError);
# (2) @napi-rs/canvas's own loader then resolves its platform binary. Hoist BOTH
# the canvas package and the glibc (`-gnu`) binary package to
# /app/node_modules/@napi-rs via symlink into the .pnpm store, and drop the prebuilt .node into the canvas
# dir: the loader tries that local file (`require('./skia.<triple>.node')`)
# before the platform package, so it decides which binary runs.
#
# Hoist the version the app pins, by name, exactly like pdfjs-dist below. The
# store once held a second, older canvas that a second pdfjs-dist pulled in,
# and this step used to take whichever `find | head -1` returned first. It
# returned the old binary, which then sat next to the new loader: rendering
# still worked, but `loadImage` called an `Image.decode` the old binary does
# not have, and every preview thumbnail failed with "image.decode is not a
# function". Name the version, and fail the build when the binary that lands

# Install the migration CLI, its config dependency, and a pinned launcher for

# This install belongs to npm, not pnpm, so the `overrides` block in

# tree still arrives here at whatever version Prisma asks for. That is not
# hypothetical. `prisma@7.8.0` resolves `@prisma/config@7.8.0`, which resolves
# `deepmerge-ts@7.1.5`, and the image scan reported CVE-2026-40345 (HIGH,
# stack exhaustion on recursive merges) against `/opt/prisma-cli` on a commit
# whose dependency audit over the app tree was green. Two installs, two
# override mechanisms, one of them set. `overrides` is npm's own mechanism and
# `npm pkg set` writes it into the package.json that `npm init -y` just
# created, before anything resolves.
#
# Measured by rebuilding this exact install both ways: without the field
# `deepmerge-ts@7.1.5` lands, with it `8.0.1` lands and `prisma --version`
# still reports 7.8.0. Keep the range in step with the entry in
# `pnpm-workspace.yaml` — they are one decision applied to two package
# managers, and a fix that lands in only one of them is the defect above.

# `@hono/node-server@1.19.11` (GHSA-frvp-7c67-39w9, CVE-2026-39406) and
# `valibot@1.2.0` (CVE-2026-59952) under this path, both reached through
# `prisma -> @prisma/dev`, while the app tree carried 1.19.17 and a pin the
# npm install never reads. Rebuilding this install both ways confirms it:
# without the two fields below npm resolves 1.19.11 and 1.2.0, with them it
# resolves 1.19.17 and 1.4.2, and `prisma --version` still reports 7.8.0.

# Start period: the entrypoint migrates before the server listens, and a

# probe's 2 s database check miss once or twice without marking the container
# unhealthy (docker-compose.yml explains the numbers). The probe is Node's own
# fetch: the Debian base carries neither wget nor curl, and installing one for
# this line would add a TLS stack to the image's scan surface. A non-2xx
# answer, a refused connection and the 4 s abort all exit 1.
