feat(sync): reserve the cloud inbox target and enforce the closed sync-target space (#1091) - #1098
Conversation
…c-target space Foundations for the cloud inbox (Gentleman-Programming#1091, slice 1 of Gentleman-Programming#1013): - Reserve the cloud:inbox sync target: constant, seeded sync_state row pinned to its own inbox lifecycle, excluded from cloud:% project aggregations, and guarded so no lifecycle setter or refresh helper can ever transition it toward pending/healthy (no delivery cursor). - Reject enrolling the reserved project name inbox at the store level so no enrollment path can mint a colliding cloud:<project> target. - Add the sync_target_closed_space doctor check (severity error): any sync_state target outside {cloud, cloud:inbox, local} plus the enrolled projects' per-project targets is a foreign target finding. - Pin the protocol constraint that session/prompt telemetry still journals: server-side chunk validation and the observations FK make sessions load-bearing until routing lands (slice 2).

Count default-cloud project journal rows in CloudSyncSummary.
Line 5194 only matches cloud:%. Standard project-scoped mutations are stored under DefaultSyncTargetKey (cloud) and identified by sm.project, as ListSyncStates documents at Lines 7380-7383. This query therefore reports zero pending mutations for normal project backlog.
Include sm.target_key = DefaultSyncTargetKey in this aggregate while retaining the explicit inbox exclusion for direct target rows. Add a summary test with an unacked cloud mutation for an enrolled project.

Review follow-ups for the cloud inbox foundations: - Repair a legacy cloud:inbox sync_state row during migration: an older version could mint one with a non-inbox lifecycle and non-zero delivery cursors (for example by enrolling a project named inbox before the name was reserved). The migration now pins the lifecycle and resets the cursors, guarded so already-clean state stays untouched. - Close rows through closeRowsWithError in ListSyncStates and check store Close errors in tests so errcheck passes on new code. - Cover the closed-space check's multi-finding behavior (one finding per foreign target) and its store-read error path.

Running the promised real-data check for slice 1. Caveat first: I did not build this branch. What the check would find here: 38 of 49 targets are foreignEvery one of the 38 carries zero mutations. They are empty shells left behind by A sample of what they actually are, because the shape matters more than the count:
Two of these are worth separating from the noise:
This is good news for the PR's premise: the closed-target space is not a theoretical The one thing I'd flag before merge: severity

Went with option 2: the check stays at It now reads: enroll if the target belongs to a project you want synced, otherwise no action is required because the row is inert drift from the removed derivation fallback, it cannot advance, no data is at risk, and a later cloud-inbox slice removes these legacy rows automatically. That keeps the signal strength you validated (38 findings that are a correct diagnosis of real drift) while making each one explicitly non-actionable-but-benign instead of a dead end, which was the #1026-shaped trap you flagged. Two things on your measurement, because they were genuinely useful:
Slice 2 is next on my side once this lands. I'll take you up on the re-measurement against the same store, and yes please with a real build if the offer still stands, so the check runs instead of being projected. |

…ding mutations (Gentleman-Programming#1091) A foreign sync_state row with unacknowledged mutations is not inert drift: it records writes no configured pipeline will deliver. Split the safe_next_step selection so zero-pending rows keep the no-action inert message while pending rows direct to enroll-or-repair guidance, and pin both branches with table assertions.

Correction to my previous comment: "Every one of them is a 0-mutation shell" is wrong for one of the 38. The check's own evidence reports: 37 of 38 carry I had counted Nothing else in that comment changes: 38 findings, the target set matches my projection element by element, the seven pre-existing checks return identical verdicts, and the reserved-name rejection reproduces.
