# MACHINA Architecture Decision — S04 Completion Report

Version: `1.0.0-S04-COMPLETION`
Date: `2026-08-21`
Request ID: `M2M-MACHINA-ADR-01`
Human decision: `HP-003`
Status: `PASS / DOCUMENTATION-ONLY / NON-RUNTIME / NON-CANONICAL`

## 1. Outcome

The approved HP-003 architecture is durably recorded as one coherent bundle:

- thin non-execution envelope;
- separately versioned composable profiles;
- external loss-declaring ROTA A duplex bridge;
- distinct source ROTAS provider and inspection ROTA;
- exactly five execution owners; and
- current Sigma classified as a control dossier/PENTAGRAMA.

The ADR records the accepted, rejected, retained, and deferred alternatives,
states the authority effect of each decision, and defines the exact S06
handoff. No schema, provider, fixture, renderer, root law, deployment artifact,
or runtime was changed.

## 2. Git isolation record

| Field | Value |
|---|---|
| Local branch | `docs/machina-architecture-decision` |
| Verified integration base | `57805701d7f78ac1aff00d602a3d5a5419701498` |
| Recovery evidence commit | `dbcf87a92986497d0ef2c69a1ee1eca8cd4ed1e8` |

The report-bearing commit is the local branch tip containing this file. A Git
commit cannot embed its own object ID without changing that ID; therefore the
stable payload commit and tree are recorded above, while the exact final tip
and tree are recorded in the ignored M2M coordinator and HP-003 lifecycle
records after atomic branch publication.

The branch was constructed from the verified integration base with a temporary
index. The mixed recovery branch was used only as read-only evidence and was
not merged, rebased, or used as the source tree. The original worktree branch,
HEAD, real index, staged state, and visible status inventory remained unchanged.

## 3. Exact S04 pathset

The complete branch delta from the integration base is exactly three added
paths:

1. `_01_INTEGRATION_CANDIDATES/MACHINA_Stack/MACHINA_ARCHITECTURE_DECISION_RECORD.md`
2. `_01_INTEGRATION_CANDIDATES/MACHINA_Stack/VALIDATE_MACHINA_ARCHITECTURE_DECISION.ps1`
3. `_01_INTEGRATION_CANDIDATES/MACHINA_Stack/MACHINA_ARCHITECTURE_DECISION_COMPLETION_REPORT.md`

All paths above are relative to `AGLA_ArsGeneralisLlullApplied/`. No existing
source file was modified or deleted.

## 4. Review evidence

The review used:

- the binding HP-003 human decision;
- OPERA Q evidence dossier `OPERATUM_HP-003-Q-01.md`;
- OPERA T comparison `OPERATUM_HP-003-T-01.md`;
- `MACHINA_STACK_CROSS_IMPLICATION_AUDIT_2026-08-14.md`;
- `MACHINA_CANDIDATE_QUALIFICATION_REPORT_2026-08-16.md`;
- the aligned recovery version of `AGLA_MACHINA_CLASS_LAW.md`;
- `AGLA_ROTA_MACHINA_SCHEMA.json` and its present generic connection shape;
- `ROTA MACHINA EX ROTA.md`; and
- the ROTA A duplex implementation evidence.

Authority was preserved by type: the user decision is binding; OPERA and
development reports are analytical evidence; candidate schemas and manifests
remain candidates; canonical role/provider controls were treated as limits,
not silently rewritten.

## 5. Validation record

The following checks passed on the exact payload content:

| Check | Result |
|---|---|
| ADR structural and semantic validator | `PASS: MACHINA architecture decision validated (67 checks).` |
| UTF-8 decoding and replacement-character gate | PASS |
| Required accepted/rejected/deferred clauses | PASS |
| Five-owner and source/inspection non-collapse | PASS |
| Sigma dossier/non-kernel boundary | PASS |
| Recovery-isolation and integration-base declarations | PASS |
| Git whitespace gate on the payload commit | PASS |
| Payload commit parent | exact integration base |
| Payload changed paths | exactly two additions |
| Original worktree status inventory | unchanged at 2,078 visible records during commit construction |

Final publication additionally verifies a two-commit linear branch, an exact
three-addition delta, no upstream, no live remote ref, no promotion ancestry,
and an unchanged original worktree/index.

## 6. Non-effects and retained material

This slice does not:

- canonize or register MACHINA;
- promote `AGLA_MACHINA_CLASS_LAW.md`;
- create a sixth execution role or owner;
- implement an envelope, profile, bridge, schema, registry, fixture, adapter,
  provider, renderer, or executable Sigma kernel;
- treat schema validity as provider closure or execution;
- collapse source ROTAS into the inspection ROTA;
- merge or promote the recovery branch; or
- rebuild deployment output.

The class-law document remains an optional candidate/reference alternative.
The first profile and edge-set implementation remain outside this slice.

## 7. Lifecycle result and next gate

The technical condition for HP-003 resolution is satisfied when this branch
passes final publication verification. HP-003 can then move from `Solving` to
`Solved` as `RESOLVED / ARCHITECTURE RECORDED`.

`M2M-MACHINA-PROFILE-01` becomes `ELIGIBLE / MANUAL START REQUIRED`. It is not
started by S04. The next coordinator selection should follow portfolio
priority; at this checkpoint the unblocked P0 visual-release request
`M2M-FIGURA-A-01` precedes the P1 S06 implementation unless the maintainer
changes the execution order.
