fix(lineage): keep agent effort and speed after completion

[Bil0000]

Completed and failed native agent cards lose effort and speed. Save Codex-reported settings on each agent and use them in the shared Lineage and timeline hover card.

Scope and approval: This small fix restores missing fields in existing agent details and qualifies for the focused bug-fix exception. Previously unsaved native settings cannot be backfilled.

Verified: 172 focused tests, web/server type checks, scoped lint, and running/completed/failed cards in the real app with fake data.

Approvability

Verdict: Approved at b886695

Macroscope's review found this PR approvable — This focused fix preserves Codex-reported effort and speed metadata and passes it through existing lineage and timeline tooltips, including completed and failed agents. The contract addition is optional and backward-compatible, with targeted server replay and UI coverage.

📝 Walkthrough

Walkthrough

Codex subagent model selections now include available reasoning effort and service tier. The selection is carried in subagent records and passed through chat components to tooltips. Tests cover metadata, settings updates, and provider-native agent details.

Changes

Subagent model selection

Layer / File(s)	Summary
Selection contract and updates packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts	OrchestrationV2Subagent adds an optional modelSelection. CodexAdapterV2 decodes reasoning effort and service tier, updates selections from thread settings and reroute notifications, and retains or replaces options based on incoming values. Tests cover selection options from settings updates.
Selection registration and task projection apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts	Registration and child-thread metadata initialize model selections with available options. Subagent tasks use the recorded selection when available. Tests cover child metadata options and delayed metadata lookup.
Chat tooltip selection display apps/web/src/components/chat/SubagentTooltipContent.tsx, apps/web/src/components/chat/ThreadRelationshipsControl.tsx, apps/web/src/components/chat/V2LifecycleRow.tsx, apps/web/src/components/chat/ThreadRelationshipsControl.agents.test.tsx	Chat relationship and timeline components pass modelSelection to the tooltip. The tooltip prefers the supplied selection and uses the child-thread fallback only for app_owned subagents. Tests check provider-native agent details across running, completed, and failed statuses.

Merge Risk: 🔵 Low · up to b8866

A child agent’s hover card can omit its known reasoning effort when a model reroute arrives before registration. This is a bounded display issue, but the settings should be merged before release.

- Line 2683: Update updateSubagentSelection around previousOptions so
model/rerouted notifications that only provide toModel retain the child’s
reasoningEffort and serviceTier when valid for the rerouted model. Obtain
replacement settings before emitting the selection if those options are not
valid for the new model.
- Around line 2991-2997: Update the child-thread metadata lookup and merge
around `decodeCodexChildThread` and `updateSubagentSelection` so a selection
seeded by `spawnAgent` can still acquire missing service-tier metadata. Decode
`serviceTier` from `thread/read`, run the lookup when the selection lacks a
service-tier option even if `task.model` is already set, and merge the response
into the existing selection rather than skipping it when one exists.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Merge missing collaboration-tool effort into an existing child selection.

When model/rerouted arrives before the collabAgentToolCall completion, it stores only toModel. Registration then sees an existing selection and skips input.item.reasoningEffort. The projected child modelSelection therefore has no reasoning effort.

Update the selection handling around updateSubagentSelection so an existing
selection created by an earlier model/rerouted event is enriched with
input.reasoningEffort when it lacks the reasoningEffort option. Preserve the
reported model when updating that selection, and continue creating a selection
from input.model when none exists.
