Architecture Decision Records¶
This directory holds the project's Architecture Decision Records (ADRs). An ADR captures a single architectural decision, the context that prompted it, and the consequences that follow.
ADRs are append-only and immutable. Once an ADR is merged, it is not edited except to update its status. If a decision changes, write a new ADR that supersedes the old one.
When to write an ADR¶
Write an ADR when the team makes a decision that:
- Constrains future architecture (technology choice, service boundary, data ownership).
- Has tradeoffs the team explicitly weighed.
- Is hard to reverse, or expensive to reverse.
- Future contributors will benefit from understanding the reasoning behind.
You do not need an ADR for:
- Routine implementation choices within an already-decided architecture.
- Bug fixes.
- Pure refactors that preserve behaviour.
- Decisions that are obvious from the code itself.
If you're unsure, err toward writing one — they are cheap, and the value comes from having them when you need them.
Format¶
Use the standard ADR template:
# NNNN — <Title>
## Status
<Proposed | Accepted | Superseded by NNNN | Folded into <doc> | Deprecated>
## Context
What is the situation that prompts this decision? What forces are at play?
## Decision
What did we decide?
## Consequences
What follows from this decision — good, bad, and neutral?
Filenames are numbered and lowercase-hyphenated: 0001-use-multi-regional-architecture.md, 0002-postgres-as-primary-store.md, etc. Numbers are zero-padded to four digits and assigned sequentially.
Lifecycle¶
- Proposed — open as a PR for team review.
- Accepted — merged. The decision stands.
- Superseded by NNNN — a later ADR replaces this one. The original ADR stays in the repo; only its Status field is updated.
- Folded into
<doc>— the decision still holds, and its durable rule now lives as prose in a FEATURES / SYSTEMS / DATA_MODELS / OPERATIONS doc. The ADR body is thinned to a Context line plus a pointer to that doc, which is the canonical reference. The decision is not reversed or superseded — only its detailed restatement is consolidated into the doc that owns the rule, to keep the ADR set free of duplicated tables and formulas. The original ADR stays in the repo (append-only); only its body and Status are updated. - Distributed-fold: N/M items landed — for a batch/group ADR (multiple named sub-items under one ADR number, e.g. the
Batch N/Group Xseries) where the fold-pass reconciling the ADR against shipped code finds that only SOME of its items match live behavior.Nitems are confirmed live (verified against actual code, not assumed);M − Nremain design intent — flag each as 📐 Design-only at its fold target with the verify-first evidence (grep output / file:line), not silently left implied-shipped by a blanket "Folded" status. Distinct from plain Folded, which implies the whole ADR's content is now live prose elsewhere: a batch ADR is never "wholly Folded" if any of its items are unverified or contradicted by the current codebase — that overclaims the unshipped remainder as much as leaving the whole ADR marked Accepted with no fold at all would. Worked example: 0055 folded intocombat-resolver.mdwith 3 of its 6 items (X-D2, S-V2, S-F2) confirmed live and 3 (S-V3, S-F1, S-F4) corrected to 📐 Design-only after a 2026-08-04 verify-first pass caught the original fold silently asserting all 6 as shipped. - Deprecated — the decision no longer applies, and no replacement is needed.
Distributed-fold exit criterion. A Distributed-fold ADR graduates to plain Folded when its remaining gap between N and M closes to zero by either route, per item — never by re-labeling alone:
1. Ships — the item lands in code and its distributed doc-page citation is updated from 📐 Design-only to reflect shipped reality (verify-first: the same grep / file:line evidence standard the Index row itself already requires), or
2. Gets its own tracked entry — the item is judged intentionally not-building (superseded by a different mechanism, judged out of scope, etc.) and that judgment is recorded as its own BACKLOG.md or DECISIONS.md entry, so the "why not built" reasoning has a durable home independent of this ADR.
Once every one of an ADR's sub-items has cleared by one of those two routes, the distributed doc pages collectively carry 100% of the ADR's canonical description — nothing is left silently asserted-shipped or silently unaccounted-for — and the ADR's Index row flips from Distributed-fold: N/M to plain Folded into <doc(s)>, same as a single-decision ADR. A Distributed-fold ADR is not eligible for this flip merely because its N/M count has been stable across several re-verification passes — a shrinking-but-nonzero gap is still a gap, and "stable" is not "closed."
Re-verification cadence. A Folded or Distributed-fold entry's Index row is a claim about the current codebase, not a one-time assertion — code drifts after the fold pass lands. Periodically re-check a folded/distributed-fold entry's Index row against current code (verify-first: grep / file:line, not assumption), and record the check inline as _(re-verified YYYY-MM-DD)_ appended to the row, matching the tag format already in use throughout the Index below. This is an intentional convention, not incidental session discipline — a row with no _(re-verified …)_ tag has not been re-checked since it was written and should not be trusted as current without doing so first.
ADRs are never deleted. They are the project's decision history.
Index¶
Add an entry below for each accepted ADR. Split 2026-08-05 (WO-CANON-CLEANUP-ADR-README-ARCHIVE-TIER + INDEX-VERIFICATION-ESSAYS): Active rows keep a short open-item pointer; verification essays live in the ADR body / queue, not here. Historical rows are id + title + fold/supersede pointer only.

Cross-linking¶
When a SYSTEMS/, OPERATIONS/, ARCHITECTURE/, or FEATURES/ doc rests on an ADR, link to the ADR from that doc. Conversely, ADRs may reference the docs they constrain. See CONTRIBUTING.md → "Cross-linking rules" for the path conventions.
