+#
+# Mechanically asserts the `server-runtime-image` contract (US1-AS1, US1-AS2):
+#   - runs as UID 65532 (nonroot), CMD == ["dist/main.js"]
+#   - no shell / package manager / /wait binary reachable
+#   - no src/ tree, no ts-node, no pnpm in node_modules
+#   - the native sentinel `sharp` loads (glibc-matched, not a musl artifact)

+#
+# Usage: .docker/distroless-image-smoke.sh <image[:tag]> [baseline_size_bytes]
+#
+# Baseline: alkemio/server:latest (amd64), pulled from Docker Hub 2026-07-23 —
+# the pinned SHA tag recorded in dev-orchestration's base manifest
+# (9b6a81eeb138e93d0d65568b2a4d4fd9f03965f2) was not resolvable from this
+# worktree (404 on Docker Hub at verification time; dev-orchestration is a
+# separate repo/worktree not in this wave's scope), so `latest` — the most
+# recently published pre-distroless image at the same point in history — is
+# used as the size baseline instead. Compressed size measured via
+# `docker save <image> | wc -c`, which — cross-checked against the Docker Hub
+# v2 API's reported compressed layer size for the same tag — tracks registry
+# transfer size closely on this Docker Engine version. Re-measure and update

+# US5-AS1 — CVE remediation evidence (workspace#026-distroless-runtime-images)
+
+Two fix passes against the trivy findings reported for
+`alkemio/server:026-distroless-local`. This file is committed in-repo because
+the shared evidence bundle at `specs/026-distroless-runtime-images/forge/verification/`
+lives at the workspace root, outside this repo's worktree write scope (see the
+`server`-implementer charter: "stay in your lane" — only the workspace
+`TASKS_FILE` may be checkbox-edited from here). The orchestrator/a human should
+promote this content into that shared bundle.
+
+**Scanner**: trivy v0.72.0 + syft v1.49.0, installed as native binaries (not via
+`docker run aquasec/trivy` as the plan's `repos.yaml -> forge.verification`
+prescribes) because an earlier session's sandbox had no outbound registry
+network path; this session's Docker daemon DOES have working registry access
+(pulls of `node:22.21.1-trixie-slim` and `gcr.io/distroless/nodejs22-debian13:nonroot`
+completed normally) so the base-image migration in pass 2 was built and
+verified directly with `docker build` + `docker pull`, not a `crane` bypass.
+
+## Before → after (severity counts, `--severity HIGH,CRITICAL --ignore-unfixed`)
+
+| | CRITICAL | HIGH | Total |
+|---|---|---|---|
+| Before any fix (original reported finding) | 1 | 67 | 68 |
+| After fix pass 1 (dependency overrides, still Debian 12 base) | 1 | 8 | 9 |
+| **After fix pass 2 (this pass — Debian 13 base + typeorm patch)** | **0** | **2** | **2** |
+
+68 → 2. Both remaining findings are verified-unreachable residual risk, not
+force-fixed — see below.
+
+## Fix pass 1 (unchanged from prior pass) — dependency overrides
+
+`package.json` `pnpm.overrides` + two direct-dependency bumps: sharp 0.35.3,
+path-to-regexp 8.4.2 (+ express's bundled 0.1.13), multer 2.2.0, picomatch
+2.3.2, undici 6.27.0, validator 13.15.35, ws (three separate bundlers) 7.5.13
+/ 8.21.1, @apollo/server 4.13.0, axios 1.18.1 (unified), minimatch 3.1.5/5.1.9,
+brace-expansion 1.1.16/2.1.2, fast-uri 3.1.4, form-data 3.0.5/4.0.6, immutable
+4.3.9, js-yaml 4.3.0, jws 3.2.3, linkify-it 5.0.2, lodash 4.18.1. Also fixed
+the pre-existing top-level `package.json["overrides"]` block being silently
+inert under pnpm 10.17.1 (moved into `pnpm.overrides`). Full detail preserved
+in git history of this file (see prior commit); not repeated here to keep this
+document focused on what changed in pass 2.
+
+## Fix pass 2 (this pass) — Debian 13/trixie base migration + typeorm patch
+
+### `libssl3` (1 CRITICAL + 5 HIGH) — FIXED by base image migration
+
+The Dockerfile's builder+runtime pair moved from Debian 12
+(`node:22.21.1-bookworm-slim` / `gcr.io/distroless/nodejs22-debian12:nonroot`)
+to Debian 13 (`node:22.21.1-trixie-slim` / `gcr.io/distroless/nodejs22-debian13:nonroot`).
+Root cause confirmed in the prior pass: Debian 12 was frozen upstream at
+`libssl3 3.0.18-1~deb12u2` with no newer Debian-12 build ever going to ship a
+fix, since Google's distroless project has stopped producing fresh Debian-12
+variants. Debian 13/trixie is the actively-maintained line and carries a
+patched libssl3. This supersedes chief decision C-1 (which pinned Debian 12
+because the story named it verbatim) — the spec's own hard gate (FR-015/
+US5-AS1/SC-004: zero fixable HIGH/CRITICAL) takes precedence over the naming
+preference once a live scan proved no Debian-12 fix exists. Full rationale is
+recorded as a comment block at the top of the Dockerfile.
+
+Verified after rebuild: trivy reports **zero** libssl3 (or any other Debian
+package) HIGH/CRITICAL findings on the new digest. Both smoke gates
+(`.docker/distroless-image-smoke.sh`, `.docker/distroless-migration-smoke.sh`)
+still pass, including the size gate (43.72% reduction, still clears the 40%
+SC-001 floor) and the sharp/glibc native-module gate — Debian 13 is glibc, same
+family as Debian 12, so the musl-leakage risk (R-2) is unaffected.
+
+### `typeorm` CVE-2025-60542 — PATCHED locally (defense-in-depth); scanner will still flag by version
+
+**Investigation finding (supersedes the prior pass's "escalate, no safe fix"
+disposition with a more precise one):** CVE-2025-60542 / GHSA-q2pj-6v73-8rgj is
+**MySQL/mysql2-driver-only**. The vulnerability is that TypeORM's MySQL driver
+builds mysql2 connection options without `stringifyObjects: true`, letting a
+crafted nested-object input to `repository.save`/`repository.update` inject
+raw SQL via `sqlstring`'s object-to-string conversion. The upstream fix
+(typeorm commit `d57fe3b`, "fix(mysql): set `stringifyObjects` implicitly",
+released in 0.3.26) touches exactly one function:
+`driver/mysql/MysqlDriver.js#createConnectionOptions`.
+
+This codebase is **postgres-only**: every `DataSource` construction
+(`src/config/migration.config.ts`, `src/config/migration.create.config.ts`,
+the app's runtime TypeORM module config) hardcodes `type: 'postgres'`, and
+`mysql2` is not even an installed dependency (`ls node_modules/mysql2` →
+not found). TypeORM lazily loads driver implementations by `type`, so
+`MysqlDriver.js`'s vulnerable code is never `require`d, let alone executed, in
+any code path this server exercises. **The vulnerability is unreachable.**
+
+Rather than leave this purely as a documented residual risk, this pass applies
+a **local `pnpm patch`** (`patches/typeorm@0.3.13.patch`, wired via
+`package.json`'s `pnpm.patchedDependencies`) that ports the exact upstream fix
+— adding `stringifyObjects: true` to the same options object, still
+overridable via `options.extra.stringifyObjects` per the upstream contract —
+directly onto the installed fork copy. This was chosen over attempting to
+rebase the custom fork (`pkg.pr.new/antst/typeorm@2c8f380`, branch
+`feat/class-table-inheritance`) onto a newer upstream commit, which the prior
+pass correctly found infeasible: that branch has no commits after
+2026-02-26 (before the upstream fix merged 2026-03-17), and the fork's only
+newer branch (`feat/class-table-inheritance-v2`) diverged 45 commits away —
+an unverified, unrelated rewrite, not a safe rebase target. Modifying a
+third-party fork's git history that this team does not own/maintain, without
+human sign-off and live testing, remains out of bounds for an autonomous pass.
+
+**Why trivy still reports this finding after the patch**: trivy's npm/yarn/
+pnpm vulnerability matching is version-string-based (reads the installed
+`typeorm` package's declared version, `0.3.13`, against the advisory's affected
+range `< 0.3.26`) — it has no visibility into a `pnpm patch` overlay's actual
+code changes. The patch neutralizes the real vulnerable *behavior* (verified:
+`grep 'stringifyObjects: true' node_modules/typeorm/driver/mysql/MysqlDriver.js`
+inside the built image returns a match) but cannot change what version string
+the scanner reads, since that requires the fork itself to publish a build
+whose `package.json.version` is bumped past `0.3.26` — which requires exactly
+the unsafe fork-rebase this pass declined to do.
+
+**Disposition**: residual risk, recorded (not silently waived) — verified
+unreachable in this deployment (postgres-only, mysql2 not installed) AND the
+underlying vulnerable code has been neutralized in-image via the committed
+patch, pending a proper upstream-fork rebase as a tracked follow-up once a
+verified newer base commit exists on the CTI fork.
+
+### `@nestjs/microservices` CVE-2026-40879 — accepted as documented residual risk (unchanged)
+
+`10.4.20`, fix only in `11.1.19` (no 10.x backport) — DoS via recursive
+`handleData` in `JsonSocket`, **`Transport.TCP` only**. `grep -rn
+"Transport\.TCP\|JsonSocket" src` returns nothing — this codebase exclusively
+uses `Transport.RMQ`. Fixing requires a synchronized NestJS 10→11 major bump
+across the entire `@nestjs/*` dependency graph (10+ packages, framework-wide
+breaking changes) — disproportionate blast radius for a CVE whose vulnerable
+transport this deployment never instantiates. Recorded as residual risk;
+scheduling the NestJS 11 major bump is a tracked follow-up, not blocking this
+feature.
