proof-introduction.txt Parent lifecycle replacement proof for PR #20072 Selected target: 13f89ae0a7fcecbdcd06ac1551d5ff549bb76926 Published candidate: d6654e616f1dcd57ff5cdc8a6289e23fead50ae8 Candidate tree: c6a9e884e51784277557e1f8ba8ba2ca3cb0e108 Candidate tree equals reviewed/fixed df8873e829ac5bcf278b2d0f88d08690e1fb9d32. Diff from selected target: 497 additions + 3 deletions = 500 lines, 11 files. Node: managed 26.12.1. Package check concurrency: 1. Vitest maximum workers: 2. Test proof The candidate's existing recursive archive/restore/delete test was overlaid on the selected target's test file, leaving all production files at the selected target. The first archive assertion failed for the intended reason: descendant state was 000000, expected 111000. The test file was then restored and the target tree verified clean before running its real server. On the candidate, the final changed-file gate passed 333 tests across 10 files, including all seven cascade case tables, three affected package typechecks, formatting, lint, both knip passes and GraphQL verification. No repository-wide checks ran. The deleted-boundary receipt records the earlier failing-then-passing extension: before df8873e829, an active grandchild below a deleted intermediate was archived (actual 1, expected 0). The primary fixed archive and restore to stop at every deleted thread, while deletion continues to surviving descendants. Seven focused cases passed afterward. This correction is included in the published tree; the former minority objection is addressed. Real server method Both runs start the real source CLI server at port 14593 with separate disposable T3 homes, then invoke orchestration.dispatchCommand over its authenticated WebSocket. A private read-only query of the installed database supplied 17 stopped thread projections and their 16 existing lineage edges, including four grandchildren. Both runs use the same snapshot. The fixture omits runs, messages, provider sessions and original event history; active provider IDs are cleared. Project workspace paths point at an empty task-owned directory. No server starts against live state. A leaf is independently archived through the real server command. The server stops, and an intermediate thread is tombstoned offline while its four grandchildren survive; two synthetic fork-boundary threads are also seeded offline. After restart, parent archive, restore and delete commands run through the server and the driver waits for all persisted outbox effects to reach a terminal state. Each run checks exact stored archive/delete state and that both fork threads remain untouched. Coverage limits This is runtime evidence for lifecycle commands and durable effect execution on copied stopped lineage and explicit boundary fixtures. It does not prove natural provider discovery or delegation, live provider/session cleanup, browser/desktop/mobile UI behavior, remote/relay behavior, or concurrency races. No provider turns or new delegated agents ran. Unit cases cover ownership, chronology, mode-limit locking, retries, process-loss replay, supersession, projects and deleted boundaries. The original PR's older Linux/Codex web evidence does not validate this design and is not reused as current proof. Review scope Existing review evidence was retained; no new review agents or broad review redo ran. The cancelled mixed panel included GPT 6 Astra, GPT 6.1 Sol, Claude Fable 5.2 and Claude Opus 5.5; adopted findings were fixed. The later panel used three GPT 6.1 Sol high seats with a weighted 3/5 majority. The primary subsequently fixed the narrow deleted-descendant boundary raised by its minority, backed by the red/green receipt. CodeRabbit follow-ups through c56b137b7c had no findings. No final-tree independent re-review is claimed. Upstream context Theo closed #20072 unmerged for conflicts and requested a fresh PR: https://github.com/pingdotgg/t3code/pull/20072#issuecomment-6820829962 The old contributor/maintainer branch stays unchanged at deafe758466ed888b0eb89f8a514c5a088008a9e. Inspected upstream main at 414d938513250edb2df7178ba737e1e630656ab7 has no equivalent lifecycle cascade. Open, unmerged #33921 overlaps archive/restore behavior; this replacement also includes deletion, durable replay and caller limits. Its overlap is disclosed, not described as a merged fix. Main invariant Windows E:/Projects/t3code and Mac /Users/luismiguelsousa/Sites/t3code remained clean at main 221a80c862a08029f0874cf0f9dbeb66f59aa2e1, tree 3c0eb73f21aa7a66de9c95c428bcf6c542d8af96. No main source, branch, commit, installation or rebuild changed. No UI leases, devices or browser tabs were acquired. before-runtime.json { "label": "before", "sha": "13f89ae0a7fcecbdcd06ac1551d5ff549bb76926", "tree": "86c9bfc7dd77a5cef64e5e76ad0858b78d5c0b8d", "node": "v26.12.1", "transport": "real server WebSocket orchestration.dispatchCommand; persisted SQLite outbox completion", "fixture": { "realStoppedThreads": 17, "relationshipEdges": 16, "nestedDescendants": 4, "syntheticForkThreads": 2, "offlineDeletedIntermediate": true, "isolatedProjectRoot": true, "omitted": "runs, messages, provider sessions, provider processes, original event history" }, "transcript": [ { "stage": "initial: independent leaf archived; intermediate tombstoned offline", "archived": [ "existing-1" ], "deleted": [ "existing-9" ], "effects": [ { "status": "succeeded", "n": 1 } ], "cascadeEffects": 0 }, { "stage": "parent archive", "archived": [ "existing-0", "existing-1" ], "deleted": [ "existing-9" ], "effects": [ { "status": "succeeded", "n": 2 } ], "cascadeEffects": 0 }, { "stage": "parent restore", "archived": [ "existing-1" ], "deleted": [ "existing-9" ], "effects": [ { "status": "succeeded", "n": 2 } ], "cascadeEffects": 0 }, { "stage": "parent delete", "archived": [ "existing-1" ], "deleted": [ "existing-0", "existing-9" ], "effects": [ { "status": "succeeded", "n": 5 } ], "cascadeEffects": 0 } ], "assertions": "passed", "limits": "Copies existing stopped thread projections and lineage only.
