[Stephen Belanger (Qard)]

A failed route enters recovery at its earliest unresolved SpanOp. Persisted typed conditions control retries: plugin bytes/chain changes, fresh credential resolution, relevant configuration changes, or capped transport/storage delays. Restart preserves these conditions; routing retries do not replay translation.

Normal delivery and recovery share flush/completion handling. Rejected batches, accepted batches awaiting ledger completion, and pending head completions retain distinct retry points. Source publication retains built chunks through append/commit failures. Status and doctor expose the stage, unresolved position, reason, and retry criterion.

Preserves #184's journaled birth provenance for every owned span. Main's append-only ledger retains pending acknowledgements until a successful write; lock, refresh, and append failures after sink acceptance are all classified for completion-only retry. Production panic assumptions are replaced with explicit handling, including recovery-evidence encoding failures.

New regressions cover all three ledger failure points, retained pending acknowledgements, successful repair, and route-head recovery without resubmitting accepted work. Existing tests cover rejected batches, credentials, plugin-chain edits, route isolation, publication failures, and restart recovery.

Based on main at f7b7683, including merged #184. Lifecycle consolidation and InputPort isolation remain in later layers. Inherits the landed checked-delivery SDK pin from #174.

Validation at 5aee065: all 533 tests pass in the locked all-feature Rust suite without exclusions or environment overrides; five live-agent tests remain normally ignored. Strict all-target/all-feature Clippy, formatting, and diff checks pass.

Rebased at 8b9e7a8: all four commits retain identical patches (git range-diff); diff checks pass. Fresh CI passes on Linux, macOS, and Windows at 8b9e7a8 (run 39305768223, attempt 3).
