grid_runtime 0.2.0-rc.13

Runtime providers for the_grid — spawns and supervises a coding agent per ready bead, isolating each bead's work in a git worktree.

0.2.0-rc.13

• Added: BeadOwnershipPredicate.admit / revoke — the live ownership allow-set widens and narrows as substations attach and detach at runtime; a double admit or an absent revoke throws StateError so the attach collision gate stays the only widening path (tg-wv9, #282).
• Floors beads_dart to ^0.2.0-rc.10.

0.2.0-rc.12

• Floors grid_trajectory to ^0.2.0-rc.4, where the re-exported StepFailureClass.noResult and StepFailureClass.invalidResult members were introduced.

0.2.0-rc.11

• Breaking: guarded GitOps methods refuse a workDir that is not a work-tree root — mutating operations and reap probes are fenced at the GitOps seam so git can never walk into an enclosing checkout (tg-amwa, #302). Migration: pass the work-tree ROOT (what git rev-parse --show-toplevel answers) as workDir; a runner fake must answer the rev-parse --show-toplevel probe (the engine's engine_fakes.dart shows the shape).
• Floors tightened to grid_trajectory ^0.2.0-rc.2.

0.2.0-rc.10

• Silent, artifact-less harness exits (a usage window running out, a network refusal) classify as infra: the restart budget is spent with backoff, then the round opens a gate naming the throttle and flares harness.throttled with the tail of the agent's output — never a gateless failed strand (tg-mbeh, #294; shipped in this rc after the tag was cut from main).
• Breaking: process groups are supervised as groups and exit status is preserved — SessionOrphaned is a new RuntimeEvent variant (emitted once, NOT terminal: the group stays supervised until it empties or the bounded grace elapses and it is signalled), so exhaustive switches over RuntimeEvent need an arm (tg-8kye, #290). Migration: add SessionOrphaned() to every switch (event); power_station#195 is the consumer fix.
• Adopts grid_trajectory 0.2.0-rc.1 (substation column).

0.2.0-rc.9

• bd 1.3.0-rc.1 compatibility rails rehearsed against the pinned upstream fixture set; a removed or renamed wire key fails the drift suite loudly (tg-1liv, #272).
• Floors tightened to beads_dart ^0.2.0-rc.7 and grid_trajectory ^0.1.2.

0.2.0-rc.8

• Breaking: none new in this candidate — it continues the 0.2.0 candidate line; grid_engine 0.3.0-rc.10 and grid_sdk 0.3.0-rc.8 were published against these fixes.
• Graph applies are serialized within each store-scoped writer so admitted pours never overlap, and a failed pour drains without poisoning the queue (#256).
• One-turn spawns close argv-only stdin immediately after binding, before process-group resolution, so a slow or failing PGID lookup cannot leave a stdin reader waiting forever (#253); a raced stop whose stdin close throws still terminates, releases, and cleans the registry (#255).

0.2.0-rc.7

• Supervised process sessions: RuntimeProvider gains write(name, bytes) and interactionOutput(name), so a long-lived process keeps stdin open and exposes a raw byte tap. Only long-lived stdout is routed through that tap — one-turn transcripts no longer accumulate unread chunks (#246).
• Stage-1 trajectory obligations (tg-zfek): the tick's shadow-posture obligation set, the stuck-obligation accountant (attempt.note(channel='obligation-stuck') plus an operator flare, leaving the obligation open), and the record-keyed settlement exclusion — a settlement whose session predates Stage 1 has no attempt_id_basis and is excluded rather than guessed (#245).

0.2.0-rc.6

• createGate's reuse/refresh branch now runs the same terminal sweep as the fresh-mint branch — a reused gate targeting a just-retired session is swept instead of dangling (#228).
• The gate-close path refactor preserves both held-session protections (disposition eligibility and the escalation-marker re-read) while supersession is applied before auto-close (#227).

0.2.0-rc.5

• Live sessions settle when their work bead closes (#215).
• Molecule reap orders topologically, so dependents retire before dependencies (#216).
• Session reap also retires the session's open mount-attempt record, un-sticking the remount budget (#220).

0.2.0-rc.4

• Guarded write capability negotiation with graceful, LOUD fallback (#205) — pairs with beads_dart 0.2.0-rc.4 (floor tightened; the rc.3 archive did not compile against any published beads_dart).
• Boot replays the positive-terminal teardown tail, so sessions completed under a dead arm settle instead of stranding (tg-tlea).
• Durable per-bead remount budget: a mount-attempt record is written at admission and consulted before remounting (tg-zlfu).

0.2.0-rc.3

• StationBeadWriter.closeOpenGatesForTerminal plus the GateCloseCause and GateSweepSessionDisposition enums: the gate auto-close sweep a terminal session runs, returning GateAutoCloseReceipts. Consumed by grid_engine's SessionScope and WorkList (tg-3eeg).
• Guarded-write capability negotiation on the bd chokepoint (tg-j0o0 groundwork).

NOTE: 0.2.0-rc.2 was published BEFORE this API landed, and the package kept accumulating source without a version bump — so the hosted rc.2 archive and the in-repo rc.2 sources differ. grid_engine 0.3.0-rc.4 shipped against the in-repo sources and does not compile against hosted rc.2; grid_engine 0.3.0-rc.5 tightens its constraint to ^0.2.0-rc.3.

0.2.0-rc.2

• StationBeadWriter.parkSessionAtGate — the session-lifecycle park distinct from the router's gate mint (tg-aec).
• reapMolecule degrades to per-bead closes on proxied-server stores, where bd batch is unsupported — the reap silently threw on EVERY session close there, the mechanism behind 9,389 orphaned step beads (tg-ehht).

0.2.0-rc.1

• Breaking: StationBeadWriter's constructor now requires reader:, a BeadProbeReader. Its seven lifecycle probes read through that seam instead of BdCliService.exportAll, which is gone (see beads_dart 0.2.0-rc.1). Migration: pass CliBeadProbeReader(bd, lifecycleTypes: …) or the SQL reader.
• Fixed: the best-effort catches around those probes no longer convert a refused bd export into a silent no-op — the reason reapMolecule never reaped and the gate mint-dedup probe always read empty.

0.1.2

• Family coherence release: StationBeadWriter current surface (onFlare, writeSpecifyAuthoredSpec/marker-gated clear the_grid#136, BeadOwnershipPredicate.ownedPrefixOf).

0.1.1

• Fixed bead-prefix matching to permit hyphens after an owned prefix (the_grid #117).

0.1.0

• Initial release: runtime providers that spawn and supervise a coding agent per ready bead, isolating each bead's work in a git worktree.
