[SOLO ORCHESTRATION CONTEXT] You are running inside Solo (Solo process ID: 831, process: Codex-phase4-cost, project: CREAM, project ID: 41). Solo MCP is available — use it to read the spec scratchpad, write your findings scratchpad, and post your REA

segment 1 of 5

Confirm Solo identity and orient on the task spec

Done

The agent executed whoami() to verify Solo identity, then read scratchpad 890 (the full Phase 4 spec) and began reading the required repo docs (CURRENT-TASK.md, docs/SOURCES.md, docs/CURRENT_STATE.md) to orient. No files were changed in this segment.

outcome

Agent identity confirmed as Codex-phase4-cost in project CREAM (process 831). Spec read from scratchpad 890.

key decisions

Follow the Solo handoff protocol: whoami first, then read scratchpad.

segment 2 of 5

Add Swift Decodable Cost struct and decode cost into TokenTotals, LatestUsage, ModelBreakdown

Done

The agent read the existing Swift model code (SessionSummary.swift), then applied a series of patches to add the Cost struct and decode it from the scanner JSON contract's nested 'cost' dicts. The cost is decoded with decodeIfPresent and falls back to 0.0. A `hasCost` property was added using a strict > 0.0 threshold.

outcome

Swift Cost struct (Decodable, Hashable, Sendable) with input/output/cacheRead/cacheWrite/total fields added. Optional `cost: Cost?` decoded on TokenTotals, LatestUsage, ModelBreakdown. SessionSummary.totalCost and hasCost added.

next steps

—

key decisions

Cost struct uses optional decode with default 0.0 so older or partial cost dictionaries are safe.
hasCost uses strict > 0.0 threshold to hide zero-cost Claude/Codex rows.

segment 3 of 5

Add formatCost helper and wire cost display into SessionRowView and SessionDetailView

Done

The agent added a formatCost helper, placed a cost MetricText in SessionRowView after the 'ctx' metric (only when hasCost), and added a per-model cost column in SessionDetailView's Models card that shows conditionally when model-level cost is present.

outcome

Row view shows cost metric in HStack after 'ctx' when hasCost. Detail view adds conditional cost column in Models card.

key decisions

Cost formatting is view-local (formatCost) to avoid widening the shared model API.
Values below $1.00 show 4 decimals ($0.XXXX); at or above $1.00 show 2 decimals ($X.XX).
Cost in the row uses Palette.secondaryValue (neutral), not provider/cache colors.

segment 4 of 5

Add Pi parser per-model cost accumulation assertions

Done

The agent added six assertion lines to test_pi_parser.py to verify that model-level cost totals are correctly accumulated and that the JSON envelope includes nested cost dicts under models[].

outcome

test_pi_parser.py now asserts per-model total_cost and the nested cost dict under models[] in the JSON envelope.

next steps

—

key decisions

Add assertions that pin per-model total_cost and the to_json shape for models[] cost.

segment 5 of 5

Update docs, verify build and tests, write findings scratchpad, post READY

Done

The agent updated CLAUDE.md and docs/CURRENT_STATE.md to reflect that Phase 4 cost surfacing is done, split the cost formatter to be view-local, ran swift build (clean) and pytest (15 passed), wrote the Solo findings scratchpad, and posted the READY comment on the tracking todo.

outcome

Both docs updated. swift build clean, 15 tests green. Findings scratchpad 891 written. READY comment posted on todo 525.

next steps

—

key decisions

Phase 4 status updated in both CLAUDE.md and docs/CURRENT_STATE.md to reflect cost is now surfaced.
Formatters moved view-local after initial shared placement for better encapsulation.
