Explanation
The PR addresses
#45464.Lockfile::mark_loaded_packagesrecords unresolved optional rows.install_with_managerretries those rows for reachable loaded packages when the lockfile is not new or frozen and no earlier failure occurred. The retry uses the found lane and records successful resolution as a lockfile diff. The reported tests cover plain install, parent re-resolution with--no-cache, lockfile updates, unchanged parent version, unresolved entries, and both linkers. These changes support recovery without a parent upgrade, full lockfile reset, or cached tarball.

Explanation
The source changes implement the retry required by
#45464. The test changes exercise optional alias recovery, lockfile persistence, scanner seeds, dropped packages, failed installs, frozen installs, tags, workspaces, and both linkers. The registry helper changes support those tests. The stated exclusions for peers, frozen installs, and unsatisfied ranges are explicit scope boundaries, not unrelated changes.

- Around line 635-652: Update the manifest parse-failure handling used by
retry_unresolved_optional_rows so failures for retried optional rows are
warnings and do not reach report_manifest_failure as errors; preserve existing
error handling for required rows and optional rows that were not retried.
Review comments at @test/cli/install/bun-lock.test.ts:
- Around line 3794-3796: Update the security-scanner test’s it.concurrent call
to remove the explicit 20_000 timeout argument and its explanatory comment,
leaving the test body and assertion unchanged.
- Around line 3676-3693: Keep the existing local regression case and add a
separate isolated global-install case alongside “by an install that asks for the
parent again.” Run both installs through installWithOwnCache with -g, verify the
parent remains cli@1.0.0 and the later install resolves cli-native from
npm:cli@1.0.0-native, then scan the global installation directory to confirm
cli-native is installed.

Beyond the inline findings, I also checked the mark_loaded_packages loop restructure in src/install/lockfile.rs — held is set under exactly the same condition as before (package_id < packages_len && !is_weak_peer), so held_at_load semantics are unchanged; and Behavior::is_optional() (src/install_types/resolver_hooks.rs:210) excludes peer rows, so the retry gate only selects the optional non-peer rows the PR describes.
Extended reasoning...
The change adds a runtime-only flag to Lockfile and a cold retry pass in install_with_manager that re-queues unresolved optional rows of reachable loaded packages, plus tests in bun-lock.test.ts and catalogs.test.ts. It touches the install resolution path and the security-scanner seed set but no auth or crypto surface. Seven inline findings were posted, including two substantive ones about new network requests on every install, so a human look is warranted; the note above records what else was examined and ruled out.
Findings marked 🟡 are optional suggestions and need no follow-up push.

A second shape of #45464, run against this branch: the exact-pinned platform packages of a tool that moves.
Every command exits 0. #45966 names this case ("an exact-pinned child of a moved package") as one it does not cover. A note for the rebase. On main 91e7e3b the source changes apply without a textual conflict, but the build fails: #45898 added the parameter Script for the steps above// Run: BUN_UNDER_TEST=/path/to/bun bun repro.ts

Fixes #45464
Problem
bun.lock. A plainbun installmakes no request for it.bun i -g pkg@latest --no-cachefetches the parent's manifest and still skips it. Codex CLI hit this: the CLI was published a few minutes before its platform package, and every later update kept the old platform binary.invalid_package_id(src/install/lockfile/bun.lock.rs,may_stay_unresolved), and the enqueue pass after load (src/install/PackageManager/install_with_manager.rs, after the differ) only queues root rows the differ changed, override rows, and extension rows. Nothing queues an unresolved row of a loaded package again.Fix
Lockfile::mark_loaded_packagessets a runtime-onlyhas_unresolved_optional_rowswhen a loaded optional (non-peer) row has no package. The loop already visits every row, so an install without such a row pays one bool store and one branch.install_with_managercalls the newretry_unresolved_optional_rowsafter the first resolve wave, when the flag is set and the lockfile is neither new nor frozen and nothing has failed yet. It queues each still-unresolved optional row of a reachable loaded package on the found lane (a second failure stays a warning, like a fresh package's rows), then runs a second wave. A row that now resolves setshad_any_diffs, so a row that re-binds to a package the tree already has still saves the lockfile and leaves the"unresolved"list. The packages a retry brings are passed to the security scanner as seeds, sincebun add <name>scans only what it adds."unresolved"list, runs in the one frame every subcommand passes through, and changes nothing when no row is unresolved. npm does the same: arborist re-resolves every missing edge on each install.test/cli/install/bun-lock.test.ts(twelve new cases under both linkers, the positive ones fail on 1.4.3). Alsobun-install,catalogs,frozen-lockfile-outdated, and before the rebasebun-install-registry,frozen-lockfile-pruned,bun-update,bun-update-transitive,bun-add,bun-add-filter,bun-audit,bun-remove,overrides,minimum-release-age,bun-install-offline,bun-install-cpu-os,bun-lockb,isolated-install,migrate-bun-lockb-v2,pnpm-lock-v9.Background
buffers.dependencies.buffers.resolutions[row]is the package it resolves to, orinvalid_package_id. A fresh install may leave an optional row unresolved (may_stay_unresolved), andbun.lockthen has no package entry for it. When a package of the same name is in the tree, the writer lists the row under"unresolved"so that loading does not bind it to that package.bind_existingwhen the parent re-binds from a manifest: it only reaches installs that resolve the parent again, so a plainbun install,--no-cache, barebun update, and root-owned rows stay wrong, and its hook sits in the arm that fires hundreds of times per fresh install. Considered an unconditional scan over every row after load: same result, but every install pays a second pass.Downsides
warn:line again. Measured with K=3: 3 requests and 3 warn lines per install, main: 0 after the first.--offline,--frozen-lockfileand--productionmake no request. npm makes the same K requests once its cache expires, and none inside its window.bun addtoday. A registry that drops packets stalls the install for the same connect timeouts any install that needs a manifest pays. Main did neither, because it never asked. Both are bounded by the existing manifest request policy, not by this PR.Notes
Measurements (debug build, local registry that logs requests):
warn: GET ... - 404lines on each.["/@openai/codex", "/@openai/codex/-/codex-1.0.0-linux-x64.tgz"], the launcher prints1.0.0-linux-x64.bun add), a secondResolving dependenciesline prints before the retry. The re-resolve of links to dropped workspaces prints the same way.Instructions and allocations per no-op install were not measured: valgrind, heaptrack and strace are not installed in the build container. The common path adds one bool store per
Lockfileconstructed and one load plus branch at the retry gate.Scope. The retry covers optional non-peer rows, the kind #45464 reports.
may_stay_unresolvedalso lets a required peer that bun auto-installs stay unresolved. Such a peer whose version appears later is still not retried. That is a sibling for a follow-up: the peer lane has its own pass.Not in this PR:
--frozen-lockfilekeeps the lockfile as it is, so a frozen install does not retry (npm ci retries and then fails if the tree changed). Rows whose target no longer satisfies their range (#43375) are a different class and are not selected. A bundled optional row loads without its bundled bit (the loader restores it only for rows that have a package entry), so a retry that succeeds resolves it like an unbundled one.no test proof · iteration 0 · platform-specific test(s) that do not run on this machine, deferring to CI, which covers all platforms: test/cli/install/bun-lock.test.ts
