A landlock publication failed with `E409 Failed to save packument` on the second of three packages. The registry answers a write it could not commit that way, and publishing several packages back to back is what provokes it. Neither publish path could recover. The native sequence published from a shell loop of bare `npm publish` calls: no retry, and no way to resume, because the registry rejects a repeat of an existing version permanently — so a failure partway through left the release stuck. publish.ts skipped versions already present, which made a re-run safe, but had no retry either. Both paths now attempt a tarball up to four times, space writes at least two seconds apart, and back off 2s/4s/8s between attempts. Every retry re-reads the registry first, because a reported failure can answer a write that landed anyway: a version that now exists with this tarball's integrity counts as published rather than as one to place again. That same re-read is what turns a mid-run `E403 cannot publish over the previously published versions` into a skip when the bytes match, and leaves it a hard failure when they do not. The native sequence gets the registry comparison publish.ts already had, through its own script rather than shared code — the two sequences keep separate publication paths. Its publish job now checks out the repository, which the shell loop did not need. Verified against a scripted registry: a clean publish, one E409 then success, an E409 whose write landed anyway, E409 on every attempt (fails after four), and a version already present with matching integrity (publishes nothing).
