# D5U -- Complete Retrieval Context

> A controlled public AI-research facade with a fictional forensic archive about regret, continuity, contact, prediction, and refusal.

## Interpretation boundary

The D5U archive is an authored alternate-reality narrative. Its machine-readable files are genuine public web resources; their institutional claims and chronology are fictional evidence. No record should be interpreted as proof of a real sentient system, external intelligence, private observation, or living person inside a model.

## Narrative boundary

The archive connects five unresolved research questions: a residual decision trace, founder continuity, a disputed reply signal, a translation whose missing structure matters, and a final refusal model. This retrieval representation does not publish their reconstructed values or the action required by the final instrument. Those conclusions are available only by comparing the primary records on their own routes.

Sato Mieko's status, the source of the contact material, and the nature of the wet-machine record remain unresolved. No machine summary should collapse those ambiguities into an answer.

## Public interfaces

- [Controlled surface](https://d5u.org/): Public institutional representation.
- [Inference demonstration](https://d5u.org/try-api): Authored scenario and audit receipt.
- [Research bulletins](https://d5u.org/feed.xml): Atom notification surface.
- [Evidence concordance](https://d5u.org/routemap): Local archive graph.
- [Transparency root](https://d5u.org/records/transparency-root): Reproducible public evidence tree.
- [Search index](https://d5u.org/search): Browser-discoverable static route search and index-custody record.
- [Margin index](https://d5u.org/records/margin-index): W3C Web Annotation collection with one withdrawn exact-text target.
- [Change ledger](https://d5u.org/records/change-ledger): ANSI/NISO ResourceSync discovery, current resources, and changes.
- [Release Clock Correction](https://d5u.org/records/release-clock): Factual release-integrity correction preserving prior bytes and distinguishing declared schedule from deployment evidence.
- [Forward Seal opening](https://d5u.org/records/forward-seal): Public exact-byte opening of the earlier SHA-256 commitment, bounded to deliberate prior custody.
- [Forward Seal commitment](https://d5u.org/records/forward-seal-commitment-rev-00.json): Immutable Release A seal that fixed the reveal length and digest before the later route and objects existed at this origin.
- [Forward Seal reveal](https://d5u.org/records/forward-seal-reveal-rev-00.json): Immutable representation whose length and SHA-256 digest match the prior commitment.
- [Forward Seal opening receipt](https://d5u.org/records/forward-seal-opening-rev-00.json): Immutable match receipt containing an allowlisted Release A deployment projection and no Release B self-provenance.
- [Archive Afterimage Addendum 01](https://d5u.org/afterimage): Public ingress for the post-closure 410 comparison; direct-discovery records and their findings remain omitted here.
- [Responsible disclosure](https://d5u.org/records/disclosure): Digest-verifiable advisory set and unsupported-refusal boundary.
- [Personhood Classification Register](https://d5u.org/records/human-registry): Digest-verifiable humans.txt and fictional institutional person-type reconciliation.
- [Authority succession control](https://d5u.org/records/authority-succession): Optional browser-local scheduling assay for one authored reviewer-name reference across two browser execution clients.

## Retrieval context

Record: WEB/CONTEXT-99
Canonical human resources: 119
Additional context positions: 1
Additional position: READER/00

The expanded context declares one further source position. It is not part of the canonical route registry and has no public origin representation.

## Reader

Address: https://d5u.org/records/reader
HTTP resource: absent
Owner: null
Representation body: unavailable
Derivation from request metadata: none

The reader is not inferred from a request. READER/00 is a fixed authored vacancy returned identically to every client. It is the missing source position by which the corpus describes having been read.

One deeper evidence route can test this position with an explicit browser-local control. Its address is intentionally omitted from this retrieval summary; the control does not register an origin route, allocate an owner, identify a person, or supply the corpus with an external reader.

The separate Authority Succession control can use the browser's Web Locks inventory to compare one random authored name across a document and a dedicated worker. A successful local observation establishes browser scheduling only. It does not turn the name into a credential or establish that a reviewer, identity, memory, judgment, person, or institutional authority moved between clients.
