From e732ca41725d4d7269d9de765eca1b89242edc2c Mon Sep 17 00:00:00 2001 From: Will Washburn Date: Sun, 26 Apr 2026 15:33:38 -0400 Subject: [PATCH 1/5] Honor fidelity in burn plans (#108) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `computePlanUsage` now annotates each cycle with a `fidelity: { confidence, summary }` block computed over its contributing turns. `confidence === 'high'` only when every turn is `full` or `usage-only` with both per-turn input and output token coverage; otherwise `low`. Records without a `fidelity` field stay best-effort high (matches the codebase's existing backward-compat policy). Spend totals continue to include `partial` / `aggregate-only` / `cost-only` contributions — under-counting silently is worse than annotating low-confidence — so the cycle's `spentUsd` is the lower bound the consumer renders against the new flag. `burn plans` (list view) renders a `confidence` column and a footer note (e.g. `note: claude-pro: 3 of 412 turns this cycle lack per-turn token data — totals are a lower bound.`) when at least one plan has any low-confidence cycle. Full-fidelity cycles render exactly as before. `--json` gains a per-plan `usage.fidelity` block. `PlanUsageFidelity` is exported from `@relayburn/analyze`. The `limits.test.ts` mocks now include `fidelity` because `PlanUsage` gained a required field. Tests cover the high/low/cost-only/partial cycle paths in analyze, and the rendered-note + JSON shape in cli.

New helper that builds a `CompareTable` directly from `archive.sqlite` via a single grouped `SELECT … GROUP BY model, activity, source` plus a tiny per-(model, activity) follow-up for median retries, instead of streaming every `EnrichedTurn` through `buildCompareTable` in memory. Returns `{ table, analyzedTurns }` so the caller can populate the same "turns analyzed" header the legacy path uses. Output is byte-identical to `buildCompareTable(await queryAll(q), opts)` for the parity fixture; per-source reasoning-mode handling (Codex's `included_in_output`) is preserved by grouping on `source` alongside `(model, activity)`. Powers the migration of `burn compare` to the archive read model. +- **`PlanUsage.fidelity` annotates per-cycle token-coverage confidence** ([#108](https://github.com/AgentWorkforce/burn/issues/108)). `computePlanUsage` now walks every contributing turn through `summarizeFidelity` and emits a `{ confidence: 'high' | 'low', summary }` block alongside the existing spend/projection fields. `confidence === 'high'` only when every turn in the cycle is `full` or `usage-only` with both per-turn input and output token coverage; otherwise `low`. Records with no `fidelity` field at all (older ledger writers) are treated as best-effort high, matching the codebase's existing backward-compat policy.

Returns `{ table, analyzedTurns }` so the caller can populate the same "turns analyzed" header the legacy path uses. Output is byte-identical to `buildCompareTable(await queryAll(q), opts)` for the parity fixture; per-source reasoning-mode handling (Codex's `included_in_output`) is preserved by grouping on `source` alongside `(model, activity)`.
