AletheIA Durable Decision Discipline

Goal

This document explains how AletheIA treats important decisions as durable artifacts instead of informal thread memory.

In simple terms:

if a decision changes how work should be executed, interpreted, validated, or governed, it should be recorded in a form that survives the session.

Why this matters

AI-assisted work creates a new kind of decision risk:

  • important decisions get buried in threads
  • the implementation survives, but the reasoning disappears
  • future sessions re-open solved questions
  • teams cannot tell whether a tradeoff was accidental or intentional

AletheIA wants decisions to stay:

  • reviewable
  • reusable
  • auditable
  • small enough to maintain

What counts as a durable decision

Not every thought needs an ADR.

Durable decision discipline should be used when the choice:

  • changes framework behavior
  • changes governance expectations
  • changes a contract or interpretation rule
  • creates a reusable convention
  • introduces a meaningful tradeoff
  • would be expensive to rediscover later

Good examples:

  • choosing how policy outcomes are prioritized
  • introducing a token budget model
  • defining a stable hook lifecycle
  • deciding where pilot-specific logic stops and framework logic begins

Bad examples:

  • tiny local wording edits
  • one-off implementation details with no future reuse
  • temporary notes that do not affect future work

The minimum durable decision record

A durable decision in AletheIA should answer:

  1. What was decided
  2. Why it was decided
  3. What alternatives mattered
  4. What changed because of it
  5. What remains intentionally unresolved

That is enough to preserve reasoning without turning the repo into a bureaucracy machine.

Relationship to other AletheIA artifacts

Durable decisions are not a substitute for:

  • Task Brief
  • Decision Record
  • Policy Evaluation
  • Handoff Record

They serve a different purpose.

Short-lived execution artifacts

These explain a specific task or run.

Durable decision artifacts

These explain a rule, tradeoff, or boundary that should influence future work.

For Alpha 1, AletheIA only needs a light baseline.

Recommended forms:

  • architecture note
  • ADR-style markdown
  • decision appendix inside a roadmap or governance doc

Current example:

  • docs/durable-decision-finalization-context-prompt.md

The important part is not the label. The important part is that future contributors can find and understand the reasoning.

Good decision hygiene

1. Record the decision close to the framework

Do not leave an important framework decision only in a PR description or issue comment.

2. Prefer one decision per artifact

This keeps the reasoning findable and easier to update later.

3. Record tradeoffs, not only conclusions

“We chose X” is weaker than “We chose X because Y and explicitly did not choose Z.”

4. Preserve boundaries

A durable decision should make framework boundaries clearer, not blur them.

5. Keep the record short

A short usable record is better than a perfect one nobody maintains.

Alpha 1 baseline

Alpha 1 does not need a large ADR system.

It only needs to prove that:

  • important framework decisions are not left implicit
  • rationale can be recovered later
  • roadmap changes and governance changes can be anchored in durable notes

For this reason, the current baseline can be lightweight:

  • a small durable decision guide
  • a starter-pack decision template
  • explicit references from roadmap/governance materials

When to create a durable decision artifact

Create one when at least one of these is true:

  • future work will depend on this choice
  • another contributor could reasonably make the opposite choice later
  • the choice constrains governance, contracts, or adoption
  • the choice separates pilot residue from reusable framework core

What Alpha 1 should prove with this discipline

By adding durable decision discipline, AletheIA should show that:

  • framework evolution is not only commit history
  • key tradeoffs can be understood without replaying old conversations
  • the project can stay small while still preserving architectural memory

Future evolution

Later versions may add:

  • a formal ADR index
  • decision lifecycle states
  • links between policy packs and decision notes
  • decision-aware governance checks

Alpha 1 does not need that yet.

It only needs to prove that durable reasoning belongs inside the framework.
