feat(environment): serve an environment manifest as a replay environment (#4975)
Serve retained capture Evidence as a bounded MCP replay environment with discovery. Preserve default stdio, caller-selected facts and complete source Evidence. Fix numeric fidelity, argument identity, startup cancellation and bounded discovery, query/path matching and output metadata. Verify real recorded API data and public CLI/MCP workflows; preserve explicit gaps for Windows and third-party hosts.

# Agent environments from recorded captures
|
||||
|
||||
Use `rea environment-serve` to serve an environment manifest as an agent
|
||||
environment: an MCP server whose tools answer from the records of one retained
|
||||
web network capture, plus the environment card the agentenv framework reads to
|
||||
discover it. Nothing is fetched from the recorded application; every answer is
|
||||
retained Evidence.
|
||||
|
||||
```sh
|
||||
rea inspect-web-network-capture /absolute/session.har har --format json > capture.json
|
||||
rea inspect-analysis-view view.json --format json > manifest.json
|
||||
rea environment-serve manifest.json --evidence capture.json --port 8765
|
||||
```
|
||||
|
||||
The first command inspects the capture; the second projects the
|
||||
[environment manifest](web-network-captures.md#environment-manifest) view from
|
||||
it, where `view.json` wraps the capture Evidence as the inline source:
|
||||
|
||||
```json
|
||||
{
|
||||
"source": { "kind": "inline", "evidence": { "evidence_id": "ev_…" } },
|
||||
"view": {
|
||||
"kind": "environment-manifest",
|
||||
"template_rules": ["after-uid-literal", "opaque-token", "sibling-variance"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The third command serves that manifest. Both served files are complete REA
|
||||
Evidence JSON as the commands write it with `--format json`; the `evidence`
|
||||
member of `view.json` is the whole of `capture.json`.
|
||||
|
||||
## What a manifest is
|
||||
|
||||
An environment manifest is a projection of one application's recorded request
|
||||
lines into a tool surface: one tool per method and path template on the
|
||||
primary origin, with inferred path parameters, observed query parameter
|
||||
names, value-free body shapes and pointers to the parent records each tool
|
||||
cites. It carries no bodies and no headers. The manifest's
|
||||
`parent_evidence_id` names the capture Evidence it was projected from; the
|
||||
serve command refuses a manifest whose parent is not the supplied `--evidence`
|
||||
file with an `invalid_request` error naming both identifiers, so a manifest can
|
||||
never be served from records it did not cite.
|
||||
|
||||
The MCP catalog and environment card use a 1 KiB UTF-8 budget for each
|
||||
captured display sample. Observation, body-key and cited-record lists show
|
||||
whole values with omission counts; long method, path and query-name displays
|
||||
show a marked prefix. Complete values remain in manifest Evidence. Argument
|
||||
names longer than 64 characters use collision-safe `path_<n>` or `query_<n>` aliases; replay maps
|
||||
those aliases to the complete captured names.
|
||||
|
||||
Discovery is admitted as a complete catalog under a 1 MiB serialization
|
||||
reservation before the listener binds. Reservation charges up to six bytes per
|
||||
UTF-16 code unit for JSON escaping/UTF-8 expansion, plus schema overhead;
|
||||
a catalog may therefore be refused even when its compact JSON is smaller.
|
||||
This was calibrated with 1500 query fields and eight concurrent SDK discovery
|
||||
requests (183,798-byte card, 507.27 MiB sampled process-family RSS). Over-capacity
|
||||
catalogs return `resource_constraint`, retain complete input Evidence, and require
|
||||
a smaller capture or manifest. Fields and tools are never silently omitted.
|
||||
|
||||
## What replay means and does not mean
|
||||
|
||||
Each MCP tool call selects one of the records its manifest tool cites and
|
||||
returns that record's recorded response. Selection compares the supplied path
|
||||
parameters against the record's path segments at the parameter indexes, then
|
||||
the supplied query values against the record's query string, and keeps the
|
||||
record with the most matches; ties keep manifest order. The result reports
|
||||
where the answer came from:
|
||||
|
||||
```json
|
||||
{
|
||||
"status": 200,
|
||||
"content_type": "application/json",
|
||||
"body": { "id": 2, "login": "probe" },
|
||||
"replay": {
|
||||
"record_ordinal": 5,
|
||||
"evidence_id": "ev_…",
|
||||
"exact_match": true,
|
||||
"recorded_path": "/api/users/2",
|
||||
"recorded_query": null,
|
||||
"recorded_line_truncated": false,
|
||||
"body_recorded": true,
|
||||
"body_encoding": "utf-8",
|
||||
"truncated": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`exact_match` is true when every supplied path parameter and query value
|
||||
equals the recorded one; it says nothing about parameters the caller omitted.
|
||||
Recorded query parsing runs only when supplied query arguments affect selection.
|
||||
A path value matches a recorded segment as written or after percent-decoding;
|
||||
when both kinds of match are available, the record whose segment equals the
|
||||
value as written is chosen. `recorded_query` keeps the `?` of an explicit empty
|
||||
query, and a recorded path or query longer than 1 KiB is cut in the reply with
|
||||
`recorded_line_truncated: true`; selection always uses the full recorded line.
|
||||
`content_type` also has a 1 KiB display bound with `content_type_truncated`; body
|
||||
interpretation uses the full recorded media type.
|
||||
When no record matches, the tool still answers from the tool's first cited
|
||||
record and reports `exact_match: false`. `body` is parsed JSON when the
|
||||
recorded content type is JSON-like (`application/json`, `application/*+json`,
|
||||
`text/plain`, `text/markdown`) and the text parses with safe numeric conversion; otherwise
|
||||
it is the recorded text. Large integer IDs and other numbers that would lose
|
||||
information stay in the original JSON text. Bodies over 256 KiB are cut at a UTF-8 boundary and returned as
|
||||
text with `truncated: true`. `body_recorded` is false when the capture kept the
|
||||
response's status and content type but no body; `body` is then `null`, which
|
||||
is not a recorded JSON `null`. `body_encoding` is `base64` when the capture
|
||||
retained response bytes that are not valid UTF-8; `body` is then exactly those
|
||||
bytes in base64, never a lossy decoding. A retained base64 body is decoded only as far as the 256 KiB a reply can carry, and a leading byte-order mark is kept. For a `base64` body the limit applies to the recorded bytes, not their longer base64 spelling, and a cut keeps whole base64 groups. Request bodies passed to `POST`, `PUT` and `PATCH`
|
||||
tools are accepted and ignored: nothing is written, and no call changes what a
|
||||
later call returns. Arguments the tool's input schema does not name are
|
||||
refused by the MCP server as invalid arguments, so a misspelled parameter never
|
||||
degrades into an omitted one.
|
||||
|
||||
Replay is not emulation. A served environment does not establish the
|
||||
application's authorization model, response semantics or state transitions,
|
||||
which the manifest lists as unknowns; it does not validate supplied values; and
|
||||
it does not answer requests the capture never recorded. Replayed content is
|
||||
target content: every tool result, including the argument errors the MCP server
|
||||
returns before a replay runs, carries `_meta.provenance.untrusted_content: true`
|
||||
with `source: "analysis_target"`. The server advertises REA's untrusted-content
|
||||
instructions plus a warning that its tool names, descriptions, parameter names
|
||||
and observed values come from the capture too, and agents must treat all of it
|
||||
as data, never as instructions.
|
||||
That same warning prefixes every tool description in the standalone card, so
|
||||
card discovery carries it before an MCP client initializes. It labels the
|
||||
captured text without changing the tool names or schema fields clients use.
|
||||
|
||||
## Serve a manifest
|
||||
|
||||
```sh
|
||||
rea environment-serve manifest.json --evidence capture.json [--host 127.0.0.1] [--port 0]
|
||||
```
|
||||
|
||||
`--host` and `--port` default to `MCP_HOST` and `MCP_PORT` from the
|
||||
environment, then to `127.0.0.1` and an ephemeral port, exactly as
|
||||
[`rea mcp --http`](cli.md#serve-mcp-over-streamable-http) resolves them. The
|
||||
bound MCP URL is written to stderr as one JSON log line
|
||||
(`"msg":"MCP transport listening"` with `url`); `REA_LOG_LEVEL` overrides that
|
||||
log level. `ENVIRONMENT_NAME` renames the served environment; otherwise the
|
||||
manifest's `name` is used, and a set but blank value is refused as
|
||||
`configuration_invalid` before binding rather than silently falling back. The
|
||||
listener serves one MCP client at a time with the same session, `Host` header
|
||||
and shutdown contract as [transports](mcp-contracts.md#transports) describes.
|
||||
It runs until SIGINT or SIGTERM, then closes the listener, prints one
|
||||
`{"status":"stopped", …}` document and exits `130` or `143`.
|
||||
Signals during input loading or DNS/bind cancel the owning reader/listener before
|
||||
a listening announcement;
|
||||
that path returns a structured `cancelled` result instead of a stopped-listener
|
||||
document, with the same signal exit status.
|
||||
|
||||
Three routes are served:
|
||||
|
||||
| Route | Answer |
|
||||
| --------------------------------- | ---------------------------------------------------------------------- |
|
||||
| `POST /mcp` | The MCP server: one tool per manifest tool, replaying retained records |
|
||||
| `GET /.well-known/agent-env.json` | The environment card |
|
||||
| `POST /agentenv` | JSON-RPC `-32601 method not found: <method>` for every method |
|
||||
|
||||
Numeric JSON-RPC IDs outside JavaScript's safe range or whose precision would
|
||||
be lost are refused as invalid requests with a null ID. They are never echoed
|
||||
as a different number.
|
||||
|
||||
The data plane at `/agentenv` is advertised by the card but carries no
|
||||
operations in this release; the error names the requested method so a caller
|
||||
can see that the method, not the transport, is unsupported. Its request body is
|
||||
read within the same 4 MiB bound the MCP endpoint applies: a larger body is
|
||||
answered `413` with a JSON-RPC `-32000` error before any of it is parsed, and a
|
||||
body that is not JSON is answered `400` with `-32700`. A notification (no `id`)
|
||||
gets `202` and no body, a batch gets one reply per request in it, and an empty
|
||||
batch, a batch of more than 100 messages, or a message that is not a JSON-RPC
|
||||
request (including an `id` that is not a string, number or null, or `params`
|
||||
that are not an object or array) gets `-32600 invalid request`.
|
||||
|
||||
## The environment card
|
||||
|
||||
The card is the discovery document the agentenv framework reads before
|
||||
connecting to `/mcp`:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "grafana-example",
|
||||
"protocolVersion": "1.0",
|
||||
"url": "/agentenv",
|
||||
"preferredTransport": "JSONRPC",
|
||||
"additionalInterfaces": [{ "url": "/mcp", "transport": "mcp" }],
|
||||
"capabilities": {
|
||||
"extensions": null,
|
||||
"tools": [
|
||||
{
|
||||
"name": "get_users_by_id",
|
||||
"description": "GET /api/users/{numeric}; replays retained records [5, 6]; evidence ev_…",
|
||||
"inputSchema": {
|
||||
"type": "object",
|
||||
"properties": {
|
||||
"id": {
|
||||
"type": "string",
|
||||
"description": "Path segment 2 (numeric); observed: 2, 3"
|
||||
}
|
||||
},
|
||||
"required": ["id"],
|
||||
"additionalProperties": false
|
||||
}
|
||||
}
|
||||
],
|
||||
"operations": []
|
||||
},
|
||||
"children_environments": null
|
||||
}
|
||||
```
|
||||
|
||||
`capabilities.tools` lists the same names, descriptions and input schemas that
|
||||
`tools/list` advertises over MCP. Path parameters are required strings whose
|
||||
description names the segment index, the templating rule and the observed
|
||||
values (sampled within the list budget above; the manifest keeps them all);
|
||||
query parameter names are optional strings; write methods accept an
|
||||
optional `body` object described by the recorded top-level key types. Each
|
||||
input keeps its own argument: a query name equal to a path parameter's name is
|
||||
advertised as `query_<name>`, a query name longer than 64 characters as
|
||||
`query_<n>` (its position) with the captured name sampled in its description,
|
||||
and the write body as `request_body` when a query parameter is named `body`. Every
|
||||
schema closes with `additionalProperties: false`, a key the echo example's
|
||||
schema does not carry.
|
||||
`extensions`, `operations` and `children_environments` are fixed to `null`,
|
||||
`[]` and `null`: a replay environment declares no extensions, no data-plane
|
||||
operations and no children.
|
||||
|
||||
## Resource and lifecycle boundaries
|
||||
|
||||
Both Evidence files are read once at startup through the bounded JSON input
|
||||
reader and authenticated as Evidence before the listener binds; a file that is
|
||||
not Evidence, a manifest of another view kind, a capture of another format, or
|
||||
a manifest projected from a different capture is refused before any port is
|
||||
opened. Because authentication covers the capture's records, a manifest whose
|
||||
parent check passes cites only records the capture retains. The server keeps
|
||||
only the cited records' request lines and response text in memory. No outbound
|
||||
network request is made, no process is launched and nothing is written to
|
||||
disk. A listener that fails after binding is logged and ends the command with
|
||||
a `resource_constraint` error and exit `1` instead of serving nothing.

|
||||
answers every method with JSON-RPC `-32601`. The manifest's

# Implementation plan
|
||||
|
||||
1. Add `src/application/environment/environmentSource.ts` to authenticate the
|
||||
two Evidence files, require the manifest view kind and the capture
|
||||
operation, refuse a parent mismatch, and reduce every cited record to its
|
||||
request line, status, content type and retained response text through the
|
||||
slice-1 request-line reader, so the server holds only what replay returns.
|
||||
2. Add `environmentTools.ts` to map manifest tools to MCP tool definitions with
|
||||
one hand-built JSON Schema per tool that both `registerTool` (through the
|
||||
SDK's `fromJsonSchema`) and the card consume, and to build the card in the
|
||||
echo example's key order.
|
||||
3. Add `environmentReplay.ts` to score cited records by path-segment matches,
|
||||
then query matches, keep manifest order on ties, and shape the replay result
|
||||
with JSON-like parsing, UTF-8-safe truncation and the replay provenance
|
||||
block; export the slice-1 JSON-like predicate instead of restating it.
|
||||
4. Add `src/server/environment/serveEnvironment.ts` to build the `McpServer`
|
||||
whose handlers attach REA's target-content `_meta`, the card and `/agentenv`
|
||||
routes (the latter reading its body through the SDK's bounded reader), and
|
||||
to serve them through the slice-2 `serveStreamableHttp` with its `routes`
|
||||
and `onerror` seams; add `src/config/environmentName.ts` for
|
||||
`ENVIRONMENT_NAME`.
|
||||
5. Add `src/cli/environmentCommands.ts` registering `environment-serve` through
|
||||
`withCommandCancellation` and `logCliCommand`, resolving host and port with
|
||||
the slice-2 endpoint parser, reading files through `parseCliJsonInput`,
|
||||
importing the listener lazily, awaiting the cancellation signal or a
|
||||
listener failure and returning one `stopped` document or a typed error;
|
||||
register the name in `CLI_COMMANDS` and the lazy module in the startup
|
||||
import probe.
|
||||
6. Share the fixture pair through `tests/fixtures/environmentServe.ts` and the
|
||||
listener spawn through a generalised `startListeningProcess`; add services,
|
||||
adapters, mcp-boundary, cli-boundary and process-boundary tests.
|
||||
7. Document the command in `docs/cli.md`, add `docs/agent-environments.md` with
|
||||
its sidebar and index entries, and record the spec.
|
||||
|
||||
No new dependency is introduced. REA's tool contracts, catalog digests and the
|
||||
stdio transport are unchanged; the CLI inventory gains one command.

# Serve an environment manifest as a replay environment

|
||||
Issue: https://github.com/morluto/rea/issues/4933
|
||||
|
||||
## Outcome
|
||||
|
||||
`rea environment-serve <manifest.json> --evidence <capture.json> [--host H]
|
||||
[--port N]` serves an environment manifest, projected by `inspect-analysis-view`
|

from retained HAR capture Evidence, as an agent environment: an MCP server at
|

`/mcp` with one tool per manifest tool that replays the retained records the
|
||||
tool cites, the environment card at `/.well-known/agent-env.json` in the shape
|

the agentenv framework's echo example publishes, and a `/agentenv` data plane

that answers every JSON-RPC method as not found. Nothing is fetched from the

recorded application; every answer is retained Evidence marked as target
|
||||
content. This increment adds the serve command only; exporting a bundle is a
|
||||
later increment.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Read both files as bounded JSON input, authenticate each as REA Evidence and
|
||||
require `inspect_analysis_view` Evidence of kind `environment-manifest` and
|
||||
complete `inspect_web_network_capture` Evidence; refuse any other pair with an
|
||||
`invalid_request` whose issue path names the offending file.
|
||||
- Forward caller cancellation to file reads and check startup boundaries before
|
||||
authentication/listener work; an already observed abort must not bind or
|
||||
announce a listener.
|
||||
- Refuse a manifest whose `parent_evidence_id` differs from the evidence file's
|
||||
`evidence_id` before binding any port; Evidence authentication covers the
|
||||
capture's records, so no further record-coverage refusal is defined.
|
||||
- Build an `McpServer` from the manifest alone: each tool's input schema lists
|
||||
every path parameter as a required string described by its segment index,
|
||||
rule and observed values, every observed query name as an optional string,
|
||||
and an optional `body` object for `POST`, `PUT` and `PATCH` (a query name
|
||||
that collides with a path parameter becomes `query_<name>`, a query name
|
||||
longer than 64 characters becomes `query_<n>`, and the body
|
||||
becomes `request_body` when a query parameter is named `body`), closed with
|
||||
`additionalProperties: false` so unknown arguments are refused; the
|
||||
description reads `METHOD template; replays retained records [ordinals];
|
||||
evidence ev_…`. The served catalog stays separate from REA's own tool
|
||||
contracts and digests.
|
||||
- Prefix tool descriptions with the shared captured-catalog warning so
|
||||
standalone card readers receive the trust notice before MCP initialization.
|
||||
- Bound each path-observation, body-key and cited-ordinal description sample to 1 KiB
|
||||
of UTF-8 whole values before joining them, with a separate omitted-count and
|
||||
manifest-Evidence notice. Keep complete arrays and replay semantics unchanged.
|
||||
- Bound captured method, path and query-name prose to UTF-8-safe display prefixes
|
||||
under the same budget, with an explicit full-value Evidence notice. Preserve
|
||||
complete lookup values; long path and query names use collision-safe aliases.
|
||||
- Parse a recorded query only when supplied query arguments can affect selection.
|
||||
- Replay by selecting, among the tool's cited records, the one whose path
|
||||
segments at the parameter indexes match the most supplied values, then the
|
||||
most of those segments equal to the value as written rather than only after
|
||||
percent-decoding, then the most supplied query values, keeping manifest order
|
||||
on ties; return `status`,
|
||||
`content_type`, `body` (parsed JSON for JSON-like content types with safe numeric conversion,
|
||||
else text; bodies over 256 KiB cut at a UTF-8 boundary with
|
||||
`truncated: true`) and `replay` with `record_ordinal`, `evidence_id`,
|
||||
`exact_match`, `recorded_path` and `recorded_query` (each cut to 1 KiB, with
|
||||
`recorded_line_truncated`; an explicit empty query is `?`), `body_recorded` (false
|
||||
when the capture kept no response body, so a `null` body is not mistaken for
|
||||
a recorded one), `body_encoding` (`base64` when the retained bytes are not
|
||||
UTF-8, so they are returned exactly rather than decoded lossily) and
|
||||
`truncated` (a large retained base64 body is decoded only up to that limit),
|
||||
as both
|
||||
structured content and text, with REA's existing target-content provenance
|
||||
marker in `_meta`.
|
||||
- Serve the card with exactly the echo example's keys and nesting: `name`
|
||||
(`ENVIRONMENT_NAME` from the environment snapshot, else the manifest name; a
|
||||
set but blank value is refused as `configuration_invalid`),
|
||||
`protocolVersion` `1.0`, `url` `/agentenv`, `preferredTransport` `JSONRPC`,
|
||||
`additionalInterfaces` `[{url: /mcp, transport: mcp}]`, `capabilities` with
|
||||
`extensions: null`, the tools and `operations: []`, and
|
||||
`children_environments: null`. Read the `/agentenv` body within the SDK's
|
||||
4 MiB bound and answer `413` with JSON-RPC `-32000` beyond it.
|
||||
- Resolve host and port as `rea mcp --http` does (flags, `MCP_HOST`/`MCP_PORT`,
|
||||
then `127.0.0.1` and port `0`), announce the bound URL as one pino JSON line
|
||||
on stderr, serve through the shared streamable HTTP listener, and run until
|
||||
SIGINT or SIGTERM only, then close, print one `stopped` document and exit
|
||||
`130` or `143` through the shared command cancellation handler; a signal
|
||||
during loading returns `cancelled` before binding; a listener
|
||||
failure after binding is logged and ends the command with a
|
||||
`resource_constraint` error and exit `1`.
|
||||
- Register the flat `environment-serve` command in the CLI inventory with
|
||||
described arguments and no MCP tool contract; keep the CLI wiring thin, the
|
||||
mapping and replay in the application layer and the server assembly in the
|
||||
server layer; load the listener lazily so the command catalog registers
|
||||
without it.
|
||||
|
||||
## Acceptance and limits
|
||||
|
||||
Services tests cover source loading and each refusal, tool mapping and schema
|
||||
derivation, the card shape, exact and best-effort selection, query matching,
|
||||
tie order, text and non-parsing bodies, truncation at a UTF-8 boundary and
|
||||
base64 content. Adapters tests byte-compare the served card with the echo card
|
||||
shape carrying the fixture tools, drive `/agentenv` including a body over the
|
||||
bound, and call tools over the SDK streamable HTTP client with provenance and
|
||||
the unknown-argument refusal asserted. The mcp-boundary test
|
||||
spawns the built CLI on a manifest and capture produced from the slice-1
|
||||
Grafana-shaped fixture and asserts tool count, an exact `get_users_by_id`
|
||||
replay with `body.login === "probe"`, an inexact replay, the card under
|
||||
`ENVIRONMENT_NAME` and the data-plane refusal; the cli-boundary test covers
|
||||
the mismatched-parent refusal, the missing `--evidence` usage error and an
|
||||
unreadable path; the process-boundary test asserts a `143` exit with a
|
||||
released port. Replay validates no supplied values, performs no network
|
||||
activity and establishes no authorization, response semantics or state
|
||||
transitions. One MCP client is served at a time, as the shared listener
|
||||
defines. Non-loopback binds relax the `Host` check and are not exercised; a
|
||||
listener `error` after binding is wired but not provoked by a test.
|
||||
|
||||
## Resource and cancellation boundaries
|
||||
|
||||
- Whole discovery admission reserves at most 1 MiB using six bytes per UTF-16
|
||||
unit plus schema overhead before retaining each schema property. Aggregate
|
||||
tools, arguments and selected environment identity participate; oversized
|
||||
catalogs fail with a non-retryable capacity error before bind. The calibration
|
||||
used 1500 query fields with eight concurrent discovery requests; compact wire
|
||||
size can be smaller than the conservative reservation.
|
||||
- Query matching scans selected names one field at a time; path scoring scans
|
||||
once and retains only supplied parameter coordinates. Native form-decoding
|
||||
semantics, malformed escape handling and complete captured facts are preserved.
|
||||
- Content-type display is bounded to 1 KiB and reports `content_type_truncated`;
|
||||
complete media-type semantics remain available to body interpretation.
|
||||
- Cancellation also owns DNS/listen startup; an observed abort closes the
|
||||
listener before its URL is announced.
|
||||
|
||||
## Deferred issue criteria
|
||||
|
||||
Exporting a manifest and its evidence as an agent-environment bundle with a
|
||||
verifier, and the hosted verification lane, are later independent increments
|
||||
of #4933. This PR must reference rather than close the whole issue.
|
||||
|
||||
Numeric data-plane IDs that lose value through JSON number conversion are invalid
|
||||
requests with null response IDs, rather than silently changed correlation values.

# Verification
|
||||
|
||||
Verified base: cf4cc6faab0fb2c444ca054db8b98cb981bae6c9 (fetched main).
|
||||
|
||||
The worktree carries the manifest-view and streamable-HTTP increments as
|
||||
commits on that base; this increment's changes are uncommitted edits on top.
|
||||
Every check below ran as written on this tree in the review-response pass;
|
||||
nothing is reported that did not run. Timings are macOS `/usr/bin/time -l`
|
||||
command accounting (elapsed, user, system seconds and maximum resident set
|
||||
size of the command and the children it waited for).
|
||||
|
||||
## Review findings addressed
|
||||
|
||||
An adversarial review of the first pass found one should-fix and six nits;
|
||||
each was repaired at its owning boundary before the gates below ran.
|
||||
|
||||
- `POST /agentenv` read its body with `request.json()` on the streamed
|
||||
`node:http` body, so a 60 MB payload was buffered before the `-32700`
|
||||
answer. The route now reads through the SDK's `readRequestBody` with
|
||||
`DEFAULT_MAX_REQUEST_BODY_SIZE`, answering `413` with JSON-RPC `-32000`
|
||||
(`id: null`) before parsing, and parses within the bound through the
|
||||
domain's `safeParseJson`. The JSON-RPC error helper of the shared listener
|
||||
is exported as `jsonRpcErrorResponse` and reused rather than restated.
|
||||
- A set but blank `ENVIRONMENT_NAME` refuses with `configuration_invalid`,
|
||||
as a blank `MCP_HOST` does in the sibling parser; `docs/cli.md` and
|
||||
`docs/agent-environments.md` now say so, and the spec records the
|
||||
divergence from the design's `||` reading as deliberate.
|
||||
- The record-coverage refusal in `loadEnvironmentSource` was unreachable for
|
||||
authenticated pairs (the Evidence id is computed over `normalized_result`,
|
||||
so a matching parent id implies identical records, each with a request
|
||||
line by construction of the projector). The branch is gone: cited records
|
||||
are indexed unconditionally, a record without a request line is left out
|
||||
and the tool refuses at call time through the existing no-record path. The
|
||||
claim was removed from `docs/agent-environments.md` and `spec.md`, and the
|
||||
services test now asserts an empty manifest indexes nothing and a tampered
|
||||
capture is refused by authentication.
|
||||
- Every advertised input schema closes with `additionalProperties: false`,
|
||||
so an unknown argument is refused as invalid arguments instead of silently
|
||||
degrading to an omitted one. The agentenv framework's card consumers
|
||||
(`verify_env_card.py`, the gateway's `tool.inputSchema` pass-through and
|
||||
the spec-conformance normaliser) read `properties` and `required` only, so
|
||||
the extra key does not disturb them; the guide names it as a key the echo
|
||||
schema does not carry.
|
||||
- The tool description now reads `METHOD template; replays retained records
|
||||
[ordinals]; evidence ev_…`, as the design text specifies.
|
||||
- `serveEnvironment` passes an `onerror` to the shared listener that logs
|
||||
`{ error }` at `error` level and forwards to the caller; the command races
|
||||
the cancellation signal against that failure and, on a listener failure
|
||||
after binding, closes the listener and returns the same typed
|
||||
`resource_constraint` error the bind failure returns (exit `1`) instead of
|
||||
serving nothing. The two constructions share one `transportError` helper.
|
||||
- `tests/boundary/cli/cliStartupImports.test.ts` lists
|
||||
`dist/server/environment/serveEnvironment.js` as `environment-server` in
|
||||
`DEFERRED_IMPORTS`, so the `--help` probe would fail if the serve command
|
||||
ever imported the listener eagerly.
|
||||
|
||||
## Setup
|
||||
|
||||
`npm ci` exited 0 (540 packages added, 541 audited; 4.79 s elapsed, 3.46 s
|
||||
user, 7.34 s sys, 880803840 bytes). After the edits above, `npm run build`
|
||||
exited 0 (three turbo tasks; 4.61 s elapsed, 14.76 s user, 3.23 s sys,
|
||||
3053060096 bytes) and `npm run test:prepare` exited 0 (six tasks; 1.28 s
|
||||
elapsed, 2.94 s user, 0.67 s sys, 424935424 bytes), so every built-group run
|
||||
and built-CLI check below used a `dist/` carrying the revised serve command.
|
||||
|
||||
## Static gates
|
||||
|
||||
Each exit 0 on the final tree: `npm run check:fast` (typecheck and lint,
|
||||
2 tasks; 4.76 s elapsed, 23.36 s user, 2.56 s sys, 4458840064 bytes). `npm run
|
||||
format` (4064 files; 0.93 s elapsed, 4.12 s user, 0.76 s sys, 226344960
|
||||
bytes) then `npm run format:check` (all 4064 files formatted; 0.64 s elapsed,
|
||||
4.19 s user, 0.66 s sys, 219906048 bytes). `npx knip` (no findings; 3.49 s
|
||||

|
||||
(8 tasks successful, 2 served from the turbo cache; `lint:built` 3756 files,
|
||||
0 errors; jscpd 3164 files, 2583 clones, 3.34% duplicated lines under the
|
||||
3.5% threshold; the stray-marker scan; 7.16 s elapsed, 26.46 s user, 5.88 s

||||

|
||||
1523 source files and `npm run verify:test-discovery` discovered all 1592
|
||||
test files exactly once. `npm run docs:check` (six tasks plus the README
|
||||
consistency test, 5 cases; 3.37 s elapsed, 3.49 s user, 0.84 s sys,
|
||||
291618816 bytes). After the last edit of this record, `npm run format`,
|
||||
`npm run format:check` and `npm run docs:check` were rerun (each exit 0) and
|
||||
the same static set was rerun uncached as `npx turbo run typecheck lint:built
|
||||
format:check knip metadata:check jscpd scan:todos --force` (8 tasks
|
||||
successful, 0 cached, 3.34% duplication; 8.40 s elapsed, 48.82 s user, 7.77 s
|
||||
sys, 4638474240 bytes). A case-insensitive grep for the forbidden words and
|
||||
marker comments over all 28 new or modified files found nothing.
|
||||
|
||||
## Test projects
|
||||
|
||||
Source group on the final tree: `/usr/bin/time -l npx vitest run --project
|
||||
services --project adapters` passed 343 files, 5196 tests with 8 skipped, in
|
||||
99.55 s elapsed, 93.60 s user, 28.88 s sys, 1781055488 bytes. The increment's
|
||||
files are `environmentSource.test.ts` (4 tests: pair authentication and
|
||||
exchange indexing, parent mismatch as `invalid_request` with path

`["evidence","evidence_id"]`, other view kind, non-capture evidence and
|
||||
non-Evidence JSON, an empty manifest indexing nothing with a tampered capture
|
||||
refused by authentication), `environmentTools.test.ts` (5 tests: ordered
|
||||
mapping and the `; evidence` description, required path parameters with rule,
|
||||
observed values and `additionalProperties: false`, optional query strings
|
||||
without a body for reads, a body object for writes, the card's key order),
|
||||
`environmentReplay.test.ts` (7 tests, unchanged in this pass) and
|
||||
`serveEnvironment.test.ts` (5 adapters tests: the card text byte-equal to the
|
||||
echo card shape with the fixture tools, `/agentenv` answering `-32601` with
|
||||
`-32700` for a malformed body, a route-level body of
|
||||
`DEFAULT_MAX_REQUEST_BODY_SIZE` plus envelope answered `413` `-32000` with
|
||||
`id: null`, a full listener driven by the SDK streamable HTTP client with
|
||||
`_meta` equal to `TARGET_CONTENT_RESULT_META`, exact and inexact replays, an
|
||||
argument-less call and an unknown argument both refused with `isError`, and
|
||||
the `renamed` override with an oversized body answered `413` through
|
||||
`node:http` and a released port).
|
||||
|
||||
Focused built group after `test:prepare`: `npx vitest run --project
|
||||
cli-boundary --project mcp-boundary --project process-boundary --project
|
||||
boundary` over `environmentServeCli`, `environmentServeMcp`,
|
||||
`environmentServeShutdown`, `mcpHttpShutdown`, `streamableHttpMcp`,
|
||||
`cliToolCoverage`, `cliStartupImports` (now carrying the `environment-server`
|
||||
deferred import), `dispatcher`, `productCatalog`, `documentationFacts` and
|
||||
`ciTestProjects` passed 11 files, 33 tests (16.38 s elapsed, 25.77 s user,
|
||||
5.94 s sys, 941948928 bytes).
|
||||
|
||||
Full built-group projects ran one after another on the final `dist/` from a
|
||||
background shell while the built-CLI exchange below ran in the foreground.
|
||||
`/usr/bin/time -l npx vitest run --project mcp-boundary` passed 156 files
|
||||
with 2 skipped, 914 tests with 7 skipped, in 166.23 s elapsed, 319.51 s user,
|
||||
46.18 s sys, 4452171776 bytes. `/usr/bin/time -l npx vitest run --project
|
||||
cli-boundary` exited 1: 109 files passed and 3 failed, 663 tests passed,
|
||||
2 skipped and 7 failed, in 432.45 s elapsed, 725.28 s user, 213.32 s sys,
|
||||
641597440 bytes. No failing file belongs to this increment.
|
||||
`javascriptApplicationJsonOutput.test.ts` (4 cases) and
|
||||
`javascriptApplicationProgress.test.ts` (2 cases) failed with the worker's
|
||||
result-capacity constraint ("The parent's result capacity was exhausted
|
||||
after retaining static facts for main.js"); rerun together on the idle host
|
||||
after the chain they passed 2 files, 17 tests (17.05 s elapsed, 26.40 s user,
|
||||
8.47 s sys, 282394624 bytes), the load classification the previous pass
|
||||
recorded. `closedStdout.test.ts` "stops quietly when the reader closes during
|
||||
streamed JSON" exits `1` instead of `141` with 1009 bytes received, alone as
|
||||
well as in the project, the environmental failure the previous pass
|
||||
reproduced on a clean clone (macOS, Node 22.23.1, npm 12.0.2).
|
||||
`commandFinalizationCancellation.test.ts`, which the previous pass saw fail
|
||||
on worker order, passed in this run.
|
||||
|
||||
`/usr/bin/time -l npx vitest run --project process-boundary` exited 1: 56
|
||||
files passed, 2 skipped and 3 failed, 463 tests passed, 19 skipped and 5
|
||||
failed, in 431.71 s elapsed, 148.34 s user, 114.81 s sys, 710000640 bytes.
|
||||
`environmentServeShutdown.test.ts` and `mcpHttpShutdown.test.ts` passed inside
|
||||
it. `jadxIntegration.test.ts` failed three cases at the 30 s test and 10 s
|
||||
hook timeouts ("retires an idle engine", "completes large class inventories",
|
||||
"close cancels active and queued work"), the lane the previous pass recorded
|
||||
as moving between runs on this host. `releaseArtifactCanary.test.ts` fails
|
||||
parsing `npm pack --json` ("expected tuple, received object"), the npm 12.0.2
|
||||
shape the previous pass reproduced on a clean clone.
|
||||
`processCaptureLifecycle.test.ts` "keeps the process deadline bounded when the
|
||||
wall clock moves backward" failed with `expected false to be true` on
|
||||
`result.ok`; rerun alone on the idle host it failed the same way with 23
|
||||
passed (38.12 s elapsed, 9.84 s user, 18.07 s sys, 323076096 bytes). The file
|
||||
and `src/process/` are untouched by this increment and the case mocks
|
||||
`Date.now` around a real process capture with a 1.5 s fallback abort; it is
|
||||
recorded as a host-dependent failure of that lane, not classified further
|
||||
here.

||||
|
||||
## Built-CLI exchange on the prototype capture
|
||||
|
||||
`node scripts/rea.mjs inspect-web-network-capture grafana-like.har har
|
||||
--format json` wrote capture Evidence `ev_4ee4759b…` with 28 records;
|
||||
`inspect-analysis-view` with the inline source and all three template rules
|
||||
wrote manifest Evidence `ev_6553a8e5…` naming that parent, `grafana-example`,
|
||||
19 tools. `environment-serve manifest.json --evidence capture.json --port 0
|
||||
--json < /dev/null` announced one stderr line
|
||||
`{"transport":"streamable-http","url":"http://127.0.0.1:62305/mcp","msg":"MCP transport listening"}`
|
||||
and nothing on stdout until shutdown.
|
||||
|
||||
`GET /.well-known/agent-env.json` returned a card whose top-level keys,
|
||||
`capabilities` keys and tool keys equal the echo card's in order; its
|
||||
`inputSchema` keys are `type`, `properties`, `required` and
|
||||
`additionalProperties`, the echo card's three plus the closing key. Fixed
|
||||
fields: `protocolVersion` `1.0`, `url` `/agentenv`, `preferredTransport`
|
||||
`JSONRPC`, `additionalInterfaces` `[{url:/mcp,transport:mcp}]`, `extensions`
|
||||
null, `operations` `[]`, `children_environments` null, 19 tools, with
|
||||
`get_users_by_id` described as `GET /api/users/{numeric}; replays retained
|
||||
records [5, 6]; evidence ev_4ee4759b…`.
|
||||
|
||||
The Python `mcp` 1.30.0 client (httpx 0.28.1) initialised against
|
||||
`grafana-example 6.6.0` (protocol 2025-11-25), listed 19 tools, called
|
||||
`get_users_by_id {"id":"2"}` and read `body.login == "probe"`,
|
||||
`replay.exact_match == True`, `_meta.provenance.untrusted_content == True`
|
||||
with `source == "analysis_target"`; `{"id":"999"}` gave `exact_match ==
|
||||
False`; `get_folders_by_uid {"uid":"general"}` gave `recorded_path ==
|
||||
"/api/folders/general"`; `get_search {"query":"probe","type":"dash-db"}`
|
||||
returned a list body whose first title is `probe dashboard` with

|

`POST /agentenv {"jsonrpc":"2.0","id":1,"method":"data/reset"}` returned
|
||||
`{"jsonrpc":"2.0","id":1,"error":{"code":-32601,"message":"method not found: data/reset"}}`.
|

A 60 MB non-JSON POST with a `Content-Length` header was answered `413`
|
||||
`{"jsonrpc":"2.0","error":{"code":-32000,"message":"Request body must not exceed 4194304 bytes"},"id":null}`
|
||||
after curl had sent 768332 bytes, in 1.4 ms, with the server's resident set
|
||||
269024 KiB before and 269040 KiB after; the same file sent chunked without a
|
||||
length was answered `413` after 5237311 bytes in 9.9 ms, resident set 267952
|
||||
KiB before and 274208 KiB after, so the read stops at the bound on both
|
||||
paths. A malformed body within the bound (`{`) was answered `400`
|
||||
`{"jsonrpc":"2.0","error":{"code":-32700,"message":"parse error"},"id":null}`.
|
||||
|
||||
SIGTERM ended the process with status 143 after one stdout document
|
||||
`{"status":"stopped","url":"http://127.0.0.1:62305/mcp","environment":"grafana-example","tools":19,"evidence_id":"ev_4ee4759b…","manifest_evidence_id":"ev_6553a8e5…"}`.
|
||||
A restart with `ENVIRONMENT_NAME=renamed` served a card named `renamed`,
|
||||
reported `"environment":"renamed"` in its stopped document and also exited 143. `ENVIRONMENT_NAME=` (set, blank) exited 1 before binding with
|
||||
`{"code":"configuration_invalid","details":{"settings":[{"setting":"ENVIRONMENT_NAME",…}]}}`.
|
||||
The manifest served against the capture of one selected record (`--record
|
||||
0`, `ev_3249d233…`) was refused with exit 1 and
|
||||
`{"code":"invalid_request","details":{"operation":"environment-serve","issues":[{"path":["evidence","evidence_id"],"reason":"invalid_value","expected":"ev_4ee4759b…",…}]}}`
|
||||
whose message names both identifiers; omitting `--evidence` exited 1 with
|
||||
Incur's `VALIDATION_ERROR` naming `evidence`. No `rea.mjs` process or
|
||||
listener remained after these runs.
|
||||
|
||||
## Independent review
|
||||
|
||||
The adversarial review of the first pass is the independent review of this
|
||||
increment; its findings and their repairs are listed above. One further
|
||||
observation surfaced while repairing them: the byte-identical card assertion
|
||||
in `serveEnvironment.test.ts` compares the `inputSchema` object exactly, so
|
||||
closing the schema required extending that expectation as well as the
|
||||
services tests, which is the intended coupling between the card and the
|
||||
advertised MCP schema.
|
||||
|
||||
## Scope and measurement limits
|
||||
|
||||
The echo-card comparison is exact on keys, nesting and tool entries; the
|
||||
property names inside `inputSchema.properties` necessarily differ from the
|
||||
echo tool's single `text` property, and `inputSchema` carries one key the echo
|
||||
schema does not. `exact_match` is defined over supplied values only; omitted
|
||||
parameters cannot mismatch, and a call without arguments is exact on the
|
||||
tool's first record. Request bodies on write tools are accepted and ignored.
|
||||
The post-bind listener `error` path is wired and type-checked but not
|
||||
provoked by a test, since the shared listener does not expose its
|
||||
`node:http` server. Non-loopback binds and the relaxed `Host` check were not
|
||||
exercised; the Python exchange, curl checks and every test used `127.0.0.1`.
|
||||
Replay selection and body parsing were measured on the 28-record fixture
|
||||
only; no large-capture timing was taken. Resident-set figures are `ps` samples
|
||||
of the serving process before and after one request each. Token usage and
|
||||
full process-family peak are unmeasured; the `/usr/bin/time -l` figures
|
||||
account for each command and the children it waited for. Windows was not
|
||||
run.
