 ### Added
 
 - **`burn plans` honors per-cycle fidelity** ([#108](https://github.com/AgentWorkforce/burn/issues/108)). The list view continues to render every plan even when the cycle slice contains `partial` / `aggregate-only` / `cost-only` turns (no fidelity-based filter — `plans`, like `limits`, is permissive), but now flags low-confidence cycles so a "looks under budget" plan isn't read as authoritative. The text table grows a `confidence` column when at least one plan has any contributing turn missing per-turn input/output token data, marked `low (partial token data)`, and a footer note names the affected plan + lower-bound caveat (e.g. `note: claude-pro: 3 of 412 turns this cycle lack per-turn token data — totals are a lower bound.`). Full-fidelity cycles render exactly as before — no extra column, no footer. `--json` gains a per-plan `usage.fidelity: { confidence, summary }` block carrying the same `FidelitySummary` shape the analyze package emits elsewhere, so machine consumers can render exact counts without re-walking the ledger. `cost-only` source contributions count toward `spentUsd` and mark the cycle low-confidence on the token-coverage axis.
+- **`burn waste` honors fidelity** ([#100](https://github.com/AgentWorkforce/burn/issues/100)). The attribution path (and the `--patterns retries|failures|reverts` detectors) now hard-filters the input slice against the coverage flags each detector requires — `attributeWaste` / `aggregateBy*` need `hasToolCalls` + `hasToolResultEvents`; `reverts` additionally needs `hasRawContent` (for `editPreHash` / `editPostHash`); `compaction` is unchanged because its sidecar is independent of `TurnRecord.fidelity`. When *all* turns fall below the prereq, `burn waste` exits non-zero with a message naming the missing prerequisite and the source kinds responsible (`burn waste: 142/142 turns lack tool-call/tool-result coverage required for waste attribution. Sources: codex (per-session-aggregate, missing tool-call records, tool-result events). No waste analysis was performed.`). When *some* turns survive, the text and JSON output gain an "analyzed N of M" coverage notice that names the gap per source. `--json` now carries a `fidelity` block (`{ analyzed, excluded, summary, refused }`) mirroring `summary --json`; `--patterns` JSON additionally exposes a `perDetector` array with each detector's `required` flags and `excludedBySource` breakdown. When `compaction` is in the selection it always runs — its sidecar has no per-turn fidelity requirement — so `--patterns retries,compaction` against an aggregate-only slice produces partial output rather than refusing.
