fix(test): harden gap snapshot oracle inputs - #9306
Conversation
📝 WalkthroughWalkthroughThe gap snapshot workflow now validates the Node oracle environment, imports known-failure provenance during snapshot updates, and audits snapshot and known-failure records in both directions. Documentation and snapshot metadata reflect the required issue provenance. ChangesGap snapshot provenance
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR hardens Node and npm prerequisites and snapshot provenance, but dependency checks still allow lockfile drift that could produce non-reproducible gap results, and the release-note entry is incomplete. These are bounded follow-up items requiring owner awareness rather than production-impacting blockers. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

npm documentation npm ls verifies installed tree package.json lockfile npm ci exact package-lock behavior
💡 Result:
The npm ls command and npm ci command serve distinct purposes in managing and verifying dependency trees. npm ls The npm ls command lists installed packages and their dependencies in a tree structure [1]. It identifies extraneous, missing, and invalid packages based on the logical dependency tree rather than the physical layout of the node_modules folder [1][2]. By default, npm ls operates on the currently installed node_modules [1][3]. If an error exists in the dependency tree, such as unmet peer dependencies, npm ls will report them and exit with a non-zero exit code [4]. While npm ls displays the installed tree, it does not inherently act as a "verify against package.json and lockfile" command in the same way that npm ci ensures environment parity [1][5]. However, it can be used to detect discrepancies if the current node_modules do not align with dependency requirements [1]. You can also use the --package-lock-only flag to have npm ls output the tree described by the package-lock.json instead of the actual contents of node_modules [1][6][7]. npm ci The npm ci command is specifically designed for automated environments where a clean, predictable install is required [8][9]. Its behavior regarding package.json and package-lock.json is strict: - Requirement: The project must have an existing package-lock.json (or npm-shrinkwrap.json) [5][8]. - Verification: It verifies that the dependencies in the lockfile match those in package.json [5][8]. If they do not match, npm ci will exit with an error rather than updating the lockfile [5][8]. - Consistency: It ensures the installed tree matches the package-lock.json exactly [5][10]. If a node_modules folder already exists, it is removed before the install begins [5][8]. - Immutability: It never updates package.json or package-lock.json; the installation is essentially frozen [5][8]. In summary, npm ci is the authoritative tool for enforcing that your installed dependencies match your lockfile and package.json exactly, while npm ls is a diagnostic tool for inspecting the current state of your node_modules tree [1][5].

Enforce the lockfile dependency tree before running the suite. npm ls --depth=0 checks installed packages against package.json ranges. It does not require the installed tree to match package-lock.json. A semver-compatible version such as a different cron release can pass while package-backed gap fixtures produce different output. Run npm ci --ignore-scripts --no-audit --no-fund, or add an equivalent lockfile-aware check, before the suite.

Summary
Make the gap-suite snapshot meaningful again by refusing to compare Perry against an unpinned or dependency-incomplete Node oracle, and by requiring every accepted snapshot failure to carry issue-backed provenance.
The nine regressions reported in #9273 are not current failures: five were manufactured by a missing root
npm ci, and four were real #9244 regressions already fixed by #9247. On the pinned Node oracle, pristinemainstill has the five committed known failures.Changes
node --versiondiffers from.node-version, or when the root npm dependency graph is absent/out of sync.known_failures.jsonduring refreshes and make the offline audit cross-check the two files in both directions.Related issue
