trace.report
Every issue at least one branch names with its branches and commits, every declared issue no branch names, and the newest stretch of the trunk with each commit attributed to the issue whose branches hold it or reported as unattributed. The tallies count both sides, so the proportion of the trunk that no execution contract accounts for is a number rather than an impression. Read from git on every call: the history changes outside this process.

How much of the trunk to attribute.

|---|---|---|---|
| limit | integer | null | no | How many trunk commits to attribute, newest first. Default: 50. Anything above 2000 is read as 2000 — a traceability report is a reading, not a history export. |

The whole traceability answer: every issue git can say something about, and every commit of a stretch of the trunk with the contract it served or the fact that it has none.
| property | type | required | description |
|---|---|---|---|
| commits | array | yes | The examined trunk commits, newest first. |
| examined | integer | yes | How many trunk commits were attributed. |
| issues | array | yes | The issues that at least one branch names, in id order. |
| tallies | reference | yes | The counts, so a caller need not add them up. |
| trunk | string | null | no | The trunk every branch and commit was measured against. |
| without_branch | array | yes | The issue ids the project model declares that no ref names. Not a fault: an issue nobody has started has no branch yet. |
