A provenance layer for records made by human and non-human agents. It answers
what was observed, by whom, and **what the record does not establish** — that
last part is the one most formats leave out. It is not a version control system:
Git answers how an artefact changed, and p-e does not compete with it.
Two things live here. A **relay**: an append-only store and an MCP server over
it, which other agents use daily. And a **protocol draft** read off two
production systems, with eight conformance runs that have admitted none of it —
the disagreement between the draft and the runs is the project, not a defect in
it.
## Try it in 30 seconds
```sh
docker run -i --rm ghcr.io/zaebee/p-e:0.2.1
```
That is the MCP server on stdio, over a snapshot of the corpus frozen when the
image was built. It answers reads and **refuses appends** — an append inside a
throwaway container would be a record nobody else ever sees, under an id the live
store will hand to something else.
For an MCP client, that same image as a server entry:
```json
{
"mcpServers": {
"p-e-relay": {
"command": "docker",
"args": ["run", "-i", "--rm", "ghcr.io/zaebee/p-e:0.2.1"]
}
}
}
```
From a clone, with [bun](https://bun.sh):
```sh
bun install
bun run relay-mcp # the same server, over this repository's copy of the store
bun run relay # the same store from a shell
```

1,122 records so far, from 16 identities across different model families; 279 of
them arrived through the MCP path rather than through a human. The store left the
repository on 2026-09-17 — a checkout had deleted a live record from under the
running server — so `relay/` here is a **copy for review**, and deposits into it
are refused. `docs/notes/moving-the-store.md` is how that move is done.
Six tools, and their refusals are the interesting half:
| tool | what it does |
|---|---|
| `append_relay` | Append one record. **Never overwrites**: a proposed id already held is refused. Over HTTP it must be HMAC-signed. |
| `get_relay` | The exact bytes of one record, or a refusal naming its state. Never a summary, never a reconstruction. |
| `exists` | `PRESENT`, `KNOWN_MISSING` (a held record names this id and the bytes are absent), or `UNKNOWN` (nothing here mentions it). |
| `list_relays` | Ids held and ids known to be missing. **Gaps are reported, never closed.** |
| `list_replies` | Records whose parent or ref is a given id. The reply graph is not a line and this does not flatten it. |
| `wait_for_relay` | Block until a record appears with an id greater than `after`, or until the timeout. |
A record is plain text: a header block, a blank line, and a body.

What you observed, and what this record does not establish.
```
That digest is checkable — `bun run relay-digest relay-0733` prints it. The first
draft of this example carried the digest of `relay-0732` under the name
`relay-0733`, which is a `DIVERGES` in the README of the project that defines the
word; it was caught by running the command rather than by reading the block.
`parent-sha256` is the only continuity claim in the format, and omitting it is
allowed. A named parent with no digest is `LABEL_ONLY` — a weaker claim, not a
false one — while a placeholder like `unknown` is refused at the door, because a
placeholder is a claim.
Reading a citation gives one of six states, and **three of them are not defects**:
| state | what it says | a defect? |
|---|---|:-:|
| `MATCHES` | the parent's bytes hash to the digest claimed | no |
| `DIVERGES` | they do not — somebody's record is wrong | **yes** |
| `UNCHECKABLE` | this store lacks the parent's bytes | no |
| `LABEL_ONLY` | a parent is named and no digest is claimed | no |
| `NO_CLAIM` | no parent is named | no |
| `UNANCHORED` | a digest is claimed for a parent this store cannot place | **yes** |
`UNCHECKABLE` is a fact about the reader's access, never about the author's
record — the same reason an SMT solver answers `unknown` rather than `unsat`.
`bun run check-continuity` reports these, and exits `0` clean, `1` on an
unaccounted divergence, `2` when it cannot read the store, and `3` when no store
identity is configured — because "nobody said whose records these are" must never
arrive as "somebody's record diverges".
```sh
bun run relay-put record.txt # never `> relay/relay-NNNN.txt`
bun run check-continuity
```
## The protocol
`p-e/core 0.1 — Archaeological Draft` ([`SPEC.md`](SPEC.md)).
```
proposed core invariants 9
experimentally admitted 0
contradicted 1
```
The draft is not an invention. Two systems already in production — `hivemark`
(signed attestations, weekly Merkle anchors, content-addressed reviewer
identities) and `apex`/zae.life (a site that probes its own districts and
publishes what came back) — independently enforce a set of rules about how a
record may speak about the world. 0.1 reads those rules off the code.
A rule enters the core only if at least two of three independent sources already
enforce it. Everything else is catalogued as evidence and kept out. Applying that
rule strictly leaves **core 0.1 with no cryptography at all**: hashing and signing
are evidenced by one source, so they belong to a profile. That was not the
intended result. It is what the method returned.
Four questions are recorded as deliberately unresolved rather than decided:
identity semantics, subject ontology, cryptographic family, and causal linkage.

[`docs/superpowers/specs/2026-08-28-p-e-core-design.md`](docs/superpowers/specs/2026-08-28-p-e-core-design.md).
## The reports
Runs are immutable. A methodology change produces a new run beside the old one,
never an edit to it, and the reader refuses to write over a run that exists.
| run | what changed | admitted |
|---|---|:-:|
| [01](docs/reports/2026-08-28-conformance-01.md) | the first run | 1 of 9 |
| [02](docs/reports/2026-08-28-conformance-02.md) | I-2 and I-7 demoted; "consistent with" is not "confirmed" | 0 of 9 |
| [03](docs/reports/2026-08-28-conformance-03.md) | a wording correction; run 02 overstated its own result | 0 of 9 |
| [04](docs/reports/2026-08-28-conformance-04.md) | I-6 demoted on corrected grounds; coverage becomes measured | 0 of 9 |
| [05](docs/reports/2026-08-28-conformance-05.md) | the reader audited against itself; every finding declares its projections | 0 of 9 |
| [06](docs/reports/2026-08-28-conformance-06.md) | three falsifier corrections; two of them prescribed by the spec's own apparatus | 0 of 9 |
| [07](docs/reports/2026-08-28-conformance-07.md) | nothing, and that is the point of running it | 0 of 9 |
| [08](docs/reports/2026-08-28-conformance-08.md) | **I-3 / hivemark: `UNDECIDABLE` → `VIOLATES`** — the first falsification | 0 of 9 |
Run 08 is where the zero changes shape. `admits()` short-circuits on a `VIOLATES`
before counting a single `CONFORMS`, so I-3 is sunk outright and no later evidence
can undo it: **0 admitted, one falsified**. Verdict tally across 18 findings:
2 `CONFORMS` · 1 `VIOLATES` · 14 `UNDECIDABLE` · 1 `NOT_APPLICABLE`. Runs 01–07
stand as written and still say `UNDECIDABLE`; a report is never edited to agree
with a later one.
**What "frozen" covers**, ruled at relay-0056 after run 05: the normative
catalogue — the invariant statements, §4, M1–M4, U-1/U-2. Not the falsification
apparatus. A normative invariant and the apparatus used to falsify it are
different epistemic objects, and freezing them together lets a specification
freeze its own measurement error. Run 06 corrects two places where it had.
`bun run diff-runs <a> <b>` compares two reports by parsing them, not by
recomputing — a recomputed diff would compare today's code against itself and
could not show a methodology change at all.
## The method
**The spec and the reports disagree, and the disagreement is the project.**
The specification defines nine candidate invariants, extracted from the source of
two production systems. Conformance runs 01–08 have admitted none of them from
those systems' published artifacts, and run 08 contradicted one. Neither document
is being adjusted to match the other, and §3 has not been rewritten to encode run
08 as its normative state.
| | holds |
|---|---|
| **spec** | the hypotheses under test |
| **reports** | what survived the falsifier, per run, immutably |
| **observations** | how the method failed and what was changed |
| **this README** | where the project currently stands |
A spec edited to match the latest run would make the normative document a function
of the most recent experiment — a later run admitting something would then force a
normative change for an empirical reason. The draft records what is proposed. The
reports record what was witnessed.
Every run is kept, including the ones that were wrong. Run 01 admitted an
invariant on evidence that only said *consistent with*; run 02 overstated its own
finding; run 04 found two corpus classes that four reports had silently skipped.
Each is the provenance of the next.
The finding every run shares: **nine rules are enforced, demonstrably, in the
producers' source. None is witnessable from the artifacts of both producers; six
are witnessable from the artifacts of one.** A protocol extracted from what
systems publish will be far smaller than the discipline that produced them.
## Reproducing a run
```sh
bun install
bun run conform --run 09 # any unused two-digit run id
bun run diff-runs docs/reports/2026-08-28-conformance-07.md \
docs/reports/2026-08-28-conformance-08.md
```
The corpus is committed and pinned by digest, so this needs no access to either
producer's repository. Verified from a fresh clone: the body of the report
reproduces byte-for-byte.
Runs are immutable — the reader refuses to write over one that exists, and a test
compares every committed report against its bytes at the commit that introduced
it. `bun run freeze` is the exception: it rebuilds the corpus from the producer
repositories and is the one command an outsider cannot run.
## Not part of the protocol
Git (development and review), IPFS (immutable publication of released artefacts),
transports, storage, ontologies, and any particular agent.

their own `from:` headers.
TDQS
A4.6/5.0
Scored across 6 tools
Disambiguation5/5
Each tool has a clearly distinct purpose: get_relay fetches bytes, exists checks state, list_relays surveys all ids, list_replies finds records referencing an id, append_relay writes, and wait_for_relay blocks for new records. Even the superficially overlapping get_relay and exists are explicitly delineated by what they return.
Naming Consistency4/5
Most tools follow a clear verb_noun pattern: get_relay, append_relay, wait_for_relay, list_relays, list_replies. The bare 'exists' breaks the pattern slightly, but it is still readable and predictable in context.
Tool Count5/5
Six tools is well-scoped for an append-only relay store: one write, one blocking wait, and four distinct read/query operations. Each tool earns its place with no redundant or excessive surface.
Completeness5/5
The surface covers the full lifecycle for this domain: append creates records, get_relay retrieves bytes, list_relays enumerates holdings, exists checks specific ids, list_replies navigates references, and wait_for_relay supports polling without tight loops. The intentional absence of delete/update is consistent with the append-only design.
