RCO-14: replace the 44 hand-written HashMap inserts with const-fn rows and shared rate constants. The pin test from the previous commit holds every key and rate. Also inline the one-caller codex_cost_usd_at_date_with_pricing_snapshot.
RCO-15: callers pass a CodexParseMode to JsonlScanner::parse_codex instead of picking one of seven forwarding wrappers; parse_codex_file stays as the from-zero convenience. Removes the two dead fork wrappers (RCO-02) and merges the two timestamp comparisons into codex_timestamp_cmp.
The summary, chart snapshot, daily cost and daily token paths each re-implemented the root walk, dedup set, pricing resolver and failure accounting. They now share walk_claude_records and keep only their own aggregation. Failed records are counted per record everywhere; the count is only read through is_complete, so results are unchanged (pinned by claude_root_walk_results_agree_across_scan_paths).
📝 Walkthrough
Merge Risk: 🔵 Low · up to Runtime cost-scanning behavior shows no identified regression. Several new tests depend on the date, local files, or time zone, so they may fail later or on some developer machines. This can be fixed in follow-up work, but fixing it before merge is easy. Pre-merge checks |

Remove test-only copies of deleted production helpers, and the tests that cover only those copies.
This PR deletes format_model_name and codex_display_label from production. It recreates both inside the test module. formats_model_names (Lines 186-194) now tests the test-only copy, so it gives no coverage of shipped behavior. The test-only codex_cost_usd_with_pricing_snapshot (Lines 61-76) is a pass-through wrapper. Remove these helpers and any test that uses only them. If one wrapper is still needed, call codex_cost_usd_with_cache_write_and_pricing_snapshot directly at the call sites. The same pattern also appears in rust/src/codex_costs/tests.rs: codex_cost_usd and codex_records_cost copy deleted production code.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Isolate the home-relative roots in the public daily-token child process.
The child process sets only CLAUDE_CONFIG_DIR. In rust/src/cost_scanner/tests/claude_walk.rs (Lines 168-170), the same pattern also sets CODEXBAR_TEST_HOME, and its comment says that every home-relative root (claude-swap, Pi, OMP) resolves through that variable. get_daily_token_history("claude", 1) goes through walk_claude_records, and that walk uses claude_projects_roots(). Without CODEXBAR_TEST_HOME, this test can therefore scan the developer's real claude-swap roots. If those roots contain a malformed or preliminary row, the first assertion !incomplete fails. If they contain valid rows, the token totals no longer come only from the fixture. The test result then depends on the developer's machine.

Use cost_bucket_zone() for expected day keys.
Production code uses cost_bucket_zone().date(timestamp) when it adds Claude records. This test uses Local, so a named bucket zone can produce a different key and make the expect assertions panic. Apply the same change to the other Claude daily tests that build expected keys with Local.

Isolate the session-roots test home.
If /home/user contains Pi settings that select another session directory, this test no longer receives the default .pi root it asserts. Use tempdir() for both home and cwd.
Based on learnings, filesystem-dependent Rust tests should use isolated temporary directories.

Summary
Lane F of the behavior-preserving simplification program: cost scanning, pricing, the JSONL scanner, Codex costs, pi session cost and the spend contract. Runtime behavior should not change. Where the existing tests did not cover a lever's output, a pin test landed first: 302b654 (pricing tables), 18dd610 (Claude root walk) and a5c040e (spend activity). The other levers rely on the existing tests of the paths they touch. The four god files are split with moves only.
Rebased on

Shared cost scanner test setup lives intests/support.rs.cli/cost.rs. It pins the live host-cost renderer's dash, partial and local-title text.pub(super), which keeps the same reach.

uselines. The leaf test names did not change: 3752 before and after the splits.LOC
Measured with
loc.pyagainstorigin/main11aebd9.The test lines go up because RCO-03 moved test-only helpers from production files into test files, and because of the new pins.
Test inventory
Lane F lib tests went from 480 to 470: 22 removed and 12 added.

rust/src/codex_costs/host_costs.rsduplicate a test from the oldcli/cost.rs. The duplicate goes away once both this PR and Simplify Rust core runtime, settings and CLI (lane E) #800 are merged, since Simplify Rust core runtime, settings and CLI (lane E) #800 deletescli/cost.rs.rust/src/codex_costs.rsis also changed by Simplify Rust core runtime, settings and CLI (lane E) #800.git merge-treeagainstsimplify/rust-core-clireports no conflicts, but I have not built the merged tree. Simplify Rust core runtime, settings and CLI (lane E) #800 drops theCodexHostCostWindowre-export at lines 12-16; this PR leaves those lines alone.git merge-treeagainst Simplify Claude, Codex and Copilot providers (lane G1) #801 also reports no conflicts.Follow-ups (not done here)
len() as i64in several places. A checked helper would change overflow behavior, so it was left out.format!fixtures and priority_trace fixtures. They were left out because of the risk around byte offsets and serde key order.has_cost_usage_sources: it still has#[allow(dead_code)].core/jsonl_scanner/codex/parser.rs(992)cost_scanner/codex.rs(924)core/cost_pricing_tests.rs(901)cost_scanner/codex/priority_trace/tests/scanner.rs(846)spend_contract/tests.rs(817)finish_cache_summary: net 0 lines.No UI changes, so no CUA proof.
