Decision diary
Contract
| Field |
Bound contract |
| Trigger |
User wants to record why one world won over the others. |
| Authority |
Reversible local: writes only one decision-diary entry at the agreed diary location; rollback is version control. No remote mutation. |
| Side effect |
A decision-diary entry documenting why one world won. |
| Done |
The decision and its rationale are recorded in the decision diary. |
Inputs
Winning decision: the world or option that won. Required.
Considered worlds: every option that was on the field, including the winner. Required.
Rationale: why the winning world won and why each rejected world lost. Required.
Decision-diary location: the local file path where the entry is appended. Required; if no location is established, the user must supply it.
Optional inputs: date, surrounding context, human opinions, agent doubts, and obvious assumptions that shaped the choice.
Procedure
- Confirm the winning decision and the full set of considered worlds from the user. Do not infer a winner or invent options that were not on the field. Done when: the winning decision and all considered worlds are confirmed from the user.
- Capture why the winning world won, using the user's terms. Done when: the winning rationale is recorded in the user's own terms.
- Capture, for each rejected world, the reason it lost. Done when: every rejected world has a loss reason recorded.
- Record any human opinions, agent doubts, and obvious assumptions the user names as load-bearing for the choice. Omit this section when the user names none; do not fabricate doubts or assumptions. Done when: named opinions, doubts, and assumptions are recorded, or the section is omitted because the user named none.
- Compose one diary entry containing the winning decision, the considered worlds, the winning rationale, the per-rejected-world loss reasons, and any named opinions, doubts, or assumptions. Done when: the entry contains all five elements.
- Append the entry to the decision-diary file at the agreed location. Create the file only if the user confirms it does not yet exist and names this path as its home. Done when: the entry is appended to the diary file at the agreed location.
- Read the entry back from the diary and confirm it is persisted and readable. Done when: the entry is read back and confirmed persisted and readable.
Failure and recovery
Missing rationale: if the user cannot state why the winning world won, stop and ask for it. Do not invent or paraphrase a rationale the user did not supply.
Missing diary location: if no decision-diary path is established and the user does not supply one, stop. Do not write to an arbitrary or guessed file.
Partial write: if the entry cannot be written in full, no partial entry is committed. The diary file is left unchanged.
Blocked result: return the missing input and the unfinished entry text. Never report done when no complete, readable entry is persisted in the diary.
Output
One appended decision-diary entry at the agreed location, containing in order: winning decision, considered worlds, winning rationale, per-rejected-world loss reasons, named opinions or doubts.
