fix(javascript): keep selected-input filesystem failures typed

A selected directory that is readable but not searchable passed the R_OK
selection check, then every entry lstat failed and the result became a
generic artifact I/O failure. The selection owner now checks search
permission for directories and reads the selection metadata inside its
classifier, so EACCES/EPERM from realpath, lstat or access is a host
access denial with the selected path and system code.

Host filesystem failures that no narrower owner classifies no longer
drop their facts: EMFILE/ENFILE become a retryable capacity constraint,
and other errno failures keep artifact I/O with the host message and
system_code, syscall and path diagnostics.

Fixes #6116
Fixes #5991

+# Wider environment state coverage and tool descriptions
+
+Issue: https://github.com/morluto/rea/issues/4933
+
+## Outcome
+
+The `environment-state` view backs more read tools with state, and a served
+environment tells agents more about each tool. Read-only paths whose responses
+are not entities become documents, listed items may be identified by an
+`…Id` or `…_id` field, an item wrapped in a one-element array is located
+inside it, and reads that vary by path get their own recorded reason. Each tool description says what the tool returns and which statuses
+were recorded, and every MCP tool carries method hints. This increment adds no
+tool, view kind, provider, network activity or write effect.
+
+## Requirements
+
+- A `GET` list tool (its template does not end in a parameter) that yields no
+  item or list plan holds its latest initial value as a `document` when its
+  initial reads have one request line, whether or not the capture writes its
+  path, unless its value changed between two of those reads across any
+  recorded write (even under another root), which leaves it `fields-differ`. A
+  value whose rendered JSON exceeds 256 KiB stays `rendered-oversize` and is
+  replayed from the recorded body, which itself fit. More request lines give
+  `path-varies` when they differ by path (a template with a parameter before
+  its end) and `query-varies` when they share one path. With every such read
+  now a document, `path-varies`, `query-varies`, `body-unusable` or
+  `rendered-oversize`, the unreachable `not-entity` reason leaves the result
+  schema, and `no-identity` names item tools only. A document holds the value
+  of its one `path`.
+- When no path parameter proves an identity and no identity name identifies
+  the listed items, the `field-name` identity is the first key of the first
+  listed item, in its order, whose name ends in `Id` or `_id`, that every item
+  carries as a distinct string or number, and that at least one initial
+  recording shows distinct across two or more items. The last condition goes
+  beyond "every item carries it distinctly": one item satisfies that
+  vacuously, and a lone item's suffix-named fields are often foreign keys (a
+  reaction keyed by its user, a comment by its post), so a list that only ever
+  held one item stays a document. Empty recordings constrain no field.
+  Identity names keep precedence, also when choosing among an envelope's
+  arrays, where a suffix-named field identifies only an array of two or more
+  items.
+- An item response that is a root array of exactly one object, or an object
+  with one member holding such an array, locates its entity at `/0` or
+  `/<member>/0` when one of the identity names in that object repeats the path
+  value. Objects at the root or in one member keep precedence. `at` and
+  `replaceAt` read and replace exactly these forms besides the root and one
+  member, so the gate and renderers run unchanged.
+- An entity's state order is its earliest sighting on the timeline and it cites
+  its records in timeline order, whichever plan observed it first.
+- Each tool description reads `METHOD template; <returns>; recorded statuses
+  …; replays retained records […]; evidence ev_…` after the untrusted-catalog
+  warning. `<returns>` describes one level deep the first cited `2xx` record
+  replay answers as JSON: an object's fields, an array of objects' fields, or
+  an envelope whose member lists objects, where a list is an array of objects
+  found by the state's list rule; an empty field set reads `with no fields`.
+  Only when no `2xx` record replays as JSON does the first cited JSON record of
+  another status give it, labelled `status <code> returns …`; with no JSON
+  record it is omitted. The statuses are the manifest tool's `statuses`, the
+  one owner of that set (`no recorded status` when it is empty). Field names
+  and statuses are sampled within the description sample budget and charged
+  with the whole description to the catalog reservation before it is retained.
+  One owner in the environment source classifies each retained body as none,
+  base64, cut, JSON or text; replay answers from that classification and
+  descriptions read only its JSON case.
+- MCP tools carry `readOnlyHint` (true for the safe methods `GET`, `HEAD`,
+  `OPTIONS` and `TRACE`, and for query `POST`s),
+  `destructiveHint: true` for `DELETE` (unset for other writes, so the MCP
+  default applies, and for reads, where clients ignore it), `idempotentHint`
+  (true for the safe methods, `PUT` and `DELETE`) and `openWorldHint: false`. The
+  tool definitions own the hints and charge them to the catalog reservation;
+  the environment card keeps its `name`, `description`, `inputSchema` tool
+  shape.
+
+## Acceptance and limits
+
+Synthetic captures cover read-only documents, `path-varies` and
+`query-varies`, suffix-named identities with their key order, their
+two-item proof, empty first recordings and their precedence (including the
+choice between an envelope's arrays), a Ghost-like `{"posts":[...]}` item under
+a trailing-slash path merging with its list view, a root one-element array, a
+one-element filtered list that stays unidentified, and the pointer forms. The
+Grafana-shaped fixture covers documents for its read-only paths (its one-member
+team list among them) and object, array and enveloped-list descriptions;
+synthetic sources cover the `2xx` preference over an earlier error body, the
+first of several JSON records, the labelled fallback, the manifest's statuses,
+empty, scalar and fieldless bodies, a truncated member name, a name whose
+JSON quoting exceeds the sample, a recorded body under 256 KiB whose rendered
+JSON exceeds it, non-JSON bodies and the catalog budget; the in-process and
+compiled MCP servers advertise the
+hints. A filtered list may still answer with one element whose identity name
+repeats the requested value; list filters, pagination, lossless big integers
+and cross-endpoint entity linking remain out of scope. Documents inline whole
+recorded values and enlarge the state result; agent tokens, CPU time and peak
+memory of the state and description build were not measured.
+
+## Deferred issue criteria
+
+Serving from the state, the AgentEnv data plane and write effects remain later
+increments of #4933. This PR must reference rather than close the issue.

+Real captures (outside the test suite): the built view ran through the
+application service on the same 44 recorded captures (39 HAR, 5 browser
+scenario) with all three template rules, in 7 to 50 ms each. 42 produced a
+state, and the same two browser-scenario captures are refused with
+`resource_constraint` as on the base. The base column is the brief's baseline,
+which the same script reproduced on the base build in an earlier pass; this
+pass did not rebuild the base.

+Seven list types gained a suffix-named identity (`permissionId`, `product_id`,
+`ItemId`, `user_id`, `channel_id`, `spl_id` and `eventId`). Seven more had one
+before the two-item proof and lost it, because every initial response listed a
+single item: an Airbyte organization, a Mattermost reaction and team
+membership, and a Redpanda broker and schema reference became documents; a
+NOAA station read is `query-varies` and a Redpanda consumer read
+`path-varies`. Two Ghost item tools render from `/members/0` and `/tags/0`. A
+third Ghost item tool is located at `/posts/0` but stays `fields-differ`: its
+recordings differ by an `include` query.
+
+State result size, as the JSON length of each Evidence summed over the 42
+states: 2,677 KiB on the base and 3,196 KiB now (+19%), measured by the same
+script. The largest growth per capture is Metabase (133 to 236 KiB), Directus
+(21 to 93), Redpanda Console (26 to 68) and Vault (9 to 43). Documents take
+492,516 of the 3,274,243 UTF-8 bytes of the results now; the base held two.
+Agent tokens, CPU time and peak memory of the state view were not measured.
+
+Tool descriptions on the 44 captures' manifests: all 44 catalogs were admitted
+within their reservation. 1,336 of 1,400 tools state what they return: 1,333
+from a `2xx` record and three labelled with another status (Miniflux and
+NocoDB 404, Shlink 501), because none of their records succeeded as JSON. The
+summaries add 261,502 bytes to a 1,185,893-byte catalog of names, descriptions
+and input schemas (median 136, 95th percentile 554, maximum 1,133 bytes per
+tool); five reached the field sample bound (one Keycloak, one Lychee and three
+Sentry tools with 46 to 105 fields). The MCP annotations add 113,182 bytes to
+`tools/list` and none to the card. Building a catalog took a median 1.6 ms and
+at most 7.6 ms (Metabase), after the source was loaded. Agent tokens, CPU time
+and peak memory of the description build were not measured.
+
+After merging the environment state view's review fixes (its branch at
+6ad63bcc, which also brings main's evidence-file sources), every gate ran
+again on the merged tree: `npm run check:fast`, `npm run format:check`,
+`npx knip`, `npm run scan:todos` and `npm run docs:check` passed; `npm run
+jscpd`: 3.39% duplicated lines over 3362 files; `npx vitest run --project
+domain --project services`: 344 files, 5914 tests passed, 5 pre-existing
+skips; `npm run build:cached`, then `npm run test:focused --` the serve and
+tool-definition adapters, the serve MCP and CLI boundaries, the export CLI
+boundary, the analysis-view MCP and CLI boundaries, the compact input-schema
+budget and the analysis-detail and advertised-input-example contracts: 10
+files, 98 tests passed.
+
+The real-capture comparison was repeated on the merged code, with the base
+measured on the merged state view without this change: all 44 captures now
+produce a state, and 1,011 of 1,277 read tools are state-backed against 625
+on the base (216 item, 416 list and 379 document views against 214, 409 and
+2). Recorded reasons: `no-identity` 216 to 32 and `not-entity` 310 to none;
+`query-varies` 5 to 76 and `path-varies` 36 are document reads under more
+than one query or path; `list-differs` 35, `body-unusable` 33,
+`no-init-recording` 28, `query-body` 12, `envelope-varies` 4 are unchanged,
+and `fields-differ` is 9 to 10.
+
+Not covered here: serving from the state, the AgentEnv data plane and write
+effects, which are later increments.
+
+## After the squash onto main
+
+The branch was squashed onto main once the state-serve branch merged (166fb082). Against a merge of the previous head
+into that main, the squash keeps both sides of every conflict and drops nothing of this branch. Two tests then failed
+on it and were refitted with the oversized-document fix in 2a926a0a: the bundle test of a state catalog over the
+discovery budget uses 300 read tools, inside the window where the state's catalog is refused and replay's, with its
+response summaries, still fits (280–320 by a probe), and the rea-state validation test names the pushed document by
+the count of documents the state holds. The replay-only card test pinned main's 11,131-byte card; it now pins this
+branch's 12,818-byte card, whose descriptions name each tool's recorded responses. The branch then merged main at
+d7ca93cc without conflicts.

+# Portable managed CLI member views
+
+Issue #5148 / PR #5167. Baseline `main@3dbe314ada9f6dcc994ca4655dc0faf082503847`;
+feature integrates the original `7b3ed4d025edd24d062cde0327a53bd311e174fc`.
+The measured production-file SHA-256 manifest is in [managed-cli.json](managed-cli.json).
+These are working-tree measurements. Each trial verifies both source and the
+complete compiled CLI graph before and after execution against its explicitly
+selected build. The two roles have distinct checkout roots and compiled digests.
+Identity-audit time is included in whole-task costs and recorded separately.
+The audit reads compiled files before timing individual CLI calls, warming those
+filesystem pages; cold means disabled Node compile cache, not disk-cold startup.
+
+## Question and independent checks
+
+Report identity, selected type, source coverage, the total method count, the first
+eight complete method records, and the first sixteen assembly-wide MemberRef
+records, including continuation coverage. Keep complete original Evidence available.
+The question deliberately does not ask for every method or reference.
+
+Public artifact: [Newtonsoft.Json 13.0.3](https://www.nuget.org/packages/Newtonsoft.Json/13.0.3),
+from the NuGet flat-container archive. The 2,441,966-byte archive SHA-256 is
+`872fc189e638ab1056555b03aaa38f68bcb54286e221aa646eb1129babf63c77`.
+Selected member `lib/net6.0/Newtonsoft.Json.dll`, 712,464 bytes, SHA-256
+`22c649f75fce5be7c7ccda8880473b634ef69ecf33f5d1ab8ad892caf47d5a07`.
+Package version 13.0.3 is distinct from metadata assembly version 13.0.0.0.
+No library code is executed; REA parses PE/CLI statically.
+
+An independent Python oracle uses `dnfile==0.18.0` and `pefile==2024.8.26`.
+It finds 494 TypeDefs, 4,208 MethodDefs and 2,149 MemberRefs. The selected
+`Newtonsoft.Json.JsonConvert` has 72 methods. Every trial checks all 72 method
+tokens, names, RVAs and original signature hashes, plus the sixteen returned
+MemberRef tokens, names and signature hashes, against this oracle. This does
+not independently establish complete CIL semantics or opcode correctness.
+The full parent Evidence and requested answers are identical across all twelve
+trials; returned rows equal the exact parent slices. Selection and source
+coverage remain distinct from page exhaustion. MemberRefs remain assembly-wide.
+
+## Completed-task cost
+
+Linux x64, Node 24.18.0/npm 11.16.0. Three alternating pairs per cache condition,
+serial, one CPU; 4 GiB hard / 3 GiB early-stop family guard, no swap, 192-task
+ceiling. Every task includes actual selected-command help, all CLI calls,
+provider parsing, bundle publication/authentication, local answer extraction
+and oracle comparisons, plus both runtime-identity audits. Build, download, oracle preparation and warm priming
+are excluded. OS page cache is uncontrolled. No build/test overlapped timing.
+
+Complete mode starts two CLI processes (help plus analysis). Selected mode starts
+five (two help commands, summary/publication, methods page, MemberRef page).
+Cold disables the Node compile cache; warm primes the exact workflow once per
+runtime/mode, then still starts fresh processes with isolated HOME each trial.
+All trials complete with verified process cleanup and no OOM/resource-stop event.

+
+Context estimates include the question, supplied command recipe, all logical
+argv, actual help and stdout. Tokenizer `tiktoken==0.12.0`, `cl100k_base`.
+The reduction is 97.1% for this fixed task. There is no model invocation;
+actual billed/native-agent usage, reasoning and transport framing are unmeasured.
+The memory counter is the kernel cgroup process-family peak including file
+cache, not sampled RSS. Ranges and individual receipts are in the JSON.
+
+This is an opt-in context/portability improvement with extra latency and CPU,
+not a speed or memory optimization. Complete provider parsing and full authentication of file-supplied bundles
+remain. Fresh managed Evidence is sealed at its producing factory and reused
+without another payload clone, including low-headroom error projection. Complete output remains the default and is preferable
+for small outputs or questions requiring every row. No cache or parser cap
+was introduced.
+
+## Existing native code composition
+
+The unchanged baseline can already redirect full stdout to a file and select
+rows in code. [The measured control](managed-cli-local-control.py) returns the
+identical answer and retains the complete original Evidence. One cold run:
+11.249 s wall, 11.000 s family CPU,
+375.3 MiB kernel peak. Projection source,
+original help and returned answer together estimate 10,555 tokens; the shared
+question and launcher argv are excluded. This single-run control does not
+establish stable performance or actual native-agent usage. It does demonstrate
+that raw CLI reply savings are not universal savings over code composition.
+The additive interface supplies authenticated reusable projections through the
+same application/domain owner as MCP, without caller-maintained JSON slicing.
+
+## Correctness and resource boundaries
+
+The public CLI regression pages all eight managed collections after process
+exit, target deletion and a working-directory change. Complete parent identity,
+original row order, signatures, source/page coverage and unknowns survive.
+Existing outputs are not replaced; failed publication retains completed facts.
+
+The Evidence factory parses mutable caller data into independent trees, computes
+identity, then seals its fresh owned snapshot with active ancestry/iterators.
+It does not retain a set/array of every completed object. Existing sealed roots
+can be shared; mutable input aliases are cloned independently. General graph
+sealing keeps its separate cycle, sharing, hidden-field and atomic-failure rules.
+Managed and derived-view factories seal their own completed Evidence, so CLI
+error projection can borrow it without reauthentication or another payload copy.
+The view owner retains strict JSON normalization for optional-field contracts;
+the CLI no longer copies its already validated completed projection again.
+
+Shared heap admission traverses by depth rather than queueing every report row
+or allocating an entries array. It reserves parsed working copies and actual
+escaping expansion before cloning/hashing, reporting UTF-16 storage explicitly.
+Canonical bundle equality streams existing ordinary JSON encoder parts, preserving
+native key order, omission, negative zero and Unicode semantics without two
+whole-document strings. All production bundle readers explicitly pass their
+operation: CLI import/export/compare/inspection, retained views, MCP import/
+comparison and both native-matching read passes. Errors retain the original
+cause, cleanup primary and lease through retry.
+
+One process primitive dispatches queued callbacks and then their OS signal
+notifications. The managed producer checks it before accepting complete Evidence.
+Publication/read stages use it before their final checks. Inline, file and bundle
+CLI views share the existing command finalizer and actual resource scope; the
+finalizer checks interruption after close while preserving any primary/cleanup
+failure. Existing inline error labels remain intact. Synchronous analysis is
+cooperatively cancellable between stages, not preemptible.
+
+Four compiled publication cases (SIGINT/SIGTERM × event/actual POSIX signal)
+fail without their checkpoint and pass restored. Eight additional compiled
+completion cases cover default complete delivery and inline projection; all fail
+with only their new completion checkpoints removed and pass restored. Fixture
+hooks match the selected target path or exact parent ID. Two real Newtonsoft
+publication runs and four real default/inline completion runs retain the identical
+parent or independently checked selected summary, exit 130/143 and preserve
+committed receipts where applicable. No target library code is executed.
+
+All 556 focused tests across 36 files pass, including direct
+finalizer/cleanup ownership, WASM/Android cancellation and native matching.
+All six `npm run check` tasks plus architecture guards, and all six
+`npm run docs:check` tasks plus five README tests pass. The expanded domain
+project passes 5,617 tests in 287 files with
+3 skipped cases; this overlaps the focused gate. Its first
+batched shard hit two existing 30-second timeouts in unchanged large synthetic
+tests. Both passed isolated and in the fresh shard rerun under the same timeout;
+the cause of the batch variation is unverified. No production/timeout change
+was made for those cases. An earlier unsplit expansion was manually stopped
+before its heap ceiling; that incomplete attempt is not counted as a pass.
+
+Eight producing/operation negative controls also catch graph-sized sealing/
+admission scratch and wrong operation attribution, including native reload.
+Native built-in instrumentation is confined to the isolated process-global lane.
+Initial test-only spy/probe/schema-import issues were corrected before these
+passing gates. No actual heap exhaustion is induced. Simulated providers do not
+qualify foreign engines; Windows OS signals remain unverified locally.
+
+## Shared-reader real-artifact regression
+
+The existing Redux Toolkit 2.2.7 source/bundle task also completes through the
+updated reader with default full output schemas and compact input schemas.
+An independent Python SHA-256/path oracle verifies 180 historical files,
+99 embedded source nodes and 210 candidate relations (33 strong-location rows,
+147 unknown). Original signals and partial source coverage remain visible.
+This uses the existing explicit semantic-node cap of one for static correspondence;
+it does not establish equivalent semantic-graph coverage or behavioral equivalence.
+
+One completed task: 21.380 s wall,
+21.023 s family CPU,
+928.9 MiB kernel family peak,
+56,378 estimated context tokens (one input catalog,
+all arguments and MCP text replies; excludes output schemas, framing and model
+reasoning). Corpus/reference preparation was performed earlier and excluded.
+This is a regression verification with resource observation, not a new paired
+performance comparison. Actual model usage remains unmeasured. Details:
+[managed-cli-shared-read.json](managed-cli-shared-read.json).
+
+## Reproduction
+
+Extract the selected DLL to a private lab as `Newtonsoft.Json.dll`. Create an
+`acquisition.json` containing the URL, hashes, sizes and selected ZIP member
+shown above; never commit the DLL. Prepare the independent oracle:
+
+```bash
+uv run --no-project --with dnfile==0.18.0 --with pefile==2024.8.26 python \
+  experiments/analysis-efficiency/managed-cli-oracle.py /absolute/lab
+```
+
+Build baseline and feature separately with the pinned toolchain. Run each under
+the shared resource guard, alternating complete/selected, selected/complete,
+complete/selected for cold and warm. Use a new output directory for every run:
+
+```bash
+python3 experiments/analysis-efficiency/resource-run.py --observe-payload-exit -- \
+  node experiments/analysis-efficiency/managed-cli-task.mjs \
+  /absolute/runtime /absolute/lab /absolute/lab/pair-cold-1-selected selected cold
+```
+
+Save each guard output to the adjacent `pair-*.log`. Warm mode uses the lab's
+mode-specific compile-cache directory; prime each identical workflow once first.
+Supply a `measurement-inputs.json` with exact revisions and production hashes,
+plus `expected_runtime_bindings.complete` and `.selected`. Capture each with
+`node experiments/analysis-efficiency/managed-cli-runtime.mjs /absolute/runtime`
+after building. Bind complete to the clean baseline revision, selected to the
+feature parent revision plus tracked/untracked source digests, with different
+roots and compiled-graph digests. The collector rejects a wrong build before any
+CLI call, rechecks it afterward, and aggregation independently enforces identity.
+A real wrong-runtime attempt is rejected before analysis. A copied trial with a
+tampered revision fails aggregation; removing only that consumer guard accepts it.
+The twelve-trial aggregation reproduces without private pilots. The native
+control also requires `--measurement-inputs /absolute/lab/measurement-inputs.json`
+and performs the same before/after identity checks.
+Then aggregate with:
+
+```bash
+uv run --no-project --with tiktoken==0.12.0 python \
+  experiments/analysis-efficiency/managed-cli-costs.py /absolute/lab \
+  --output /absolute/results.json
+```
+
+The original issue reporter's executable, foreign operating systems and actual
+model sessions remain unverified. Setup pilots and earlier unbound cohorts, including one failed setup run
+while compiled artifacts were absent after a typecheck failure, are excluded.

+# MCP discovery and complete Rust tasks
+
+Target-free stdio discovery previously constructed the canonical analysis runtime before the client could inspect its directory. The candidate records SDK advertisements at build time for default/explicit compact and explicit full inputs. Its first tool, prompt or completion request materializes canonical validators and handlers on the same SDK server. HTTP, output-schema-off, initial-target and unrecorded source runs retain eager composition.
+
+Pinned baseline: [`main@c465ff5a8`](https://github.com/morluto/rea/commit/c465ff5a814b8e1a386fc547cbcd94df5c35f086). Measured candidate: [`04900abbc`](https://github.com/leeguooooo/rea/commit/04900abbcd3c3438fce4af932ff28400fe744a7d). Both use the same main base and locked dependencies. Before/after source and all compiled JS/JSON bindings identify the exact runtime used in every trial. The input manifest and producer scripts are also hashed and checked.
+
+## Real tasks and independent facts
+
+Official Alpine v3.21 packages supply ripgrep 14.1.1-r0 (3,416,168-byte executable) and Zellij 0.40.0-r0 (17,151,864 bytes). Their download URLs, archive/executable digests and aports revisions are retained in [the measurement data](mcp-startup.json). The independent Python ELF/section/zlib/JSON oracle checks 42 packages and 88 dependency edges for ripgrep, and 422 packages and 1,063 edges for Zellij. Serde versions are 1.0.210 and 1.0.137 respectively; the selected package kind remains explicit unknown (`null`). Verification covers embedded static build metadata; execution and runtime reachability remain unverified.
+
+Each analysis task initializes the actual SDK client, lists and validates the input directory, selects serde name/version/kind, reads the exact retained parent twice, verifies canonical rejection of a negative offset, exports and independently checks the complete package/edge inventory, confirms unchanged advertisements after materialization, then closes. All five tool calls and both directory reads are included in the measured task. Discovery tasks initialize, list tools/prompts, validate the input directory and close without an analysis call.
+
+All 72 paired trials and four priming runs passed. Each artifact has identical answers, parent Evidence IDs and complete semantic hashes across roles, profiles and cache modes. Both profiles retain byte-identical directories across baseline/candidate and before/after canonical materialization. The directory contains 213 tools. Complete Evidence is retained and exported through the existing shared workflow.
+
+## Measured cost
+
+Three alternating pairs per condition; table values are medians. Min/max ranges and individual receipts are in [mcp-startup.json](mcp-startup.json). Each cell is baseline → candidate. Kernel process-family peak includes file cache, SDK driver, observer and REA children.

+| zellij    | cold  | full              | 8.484 → 7.776 |      8.284 → 7.514 |   850.4 → 813.1 |
+| ripgrep   | warm  | compact (default) | 7.976 → 6.879 |      7.739 → 6.678 |   826.8 → 802.6 |

+
+Discovery improves clearly in this cohort. Completed-task changes depend on the workload: default cold ripgrep is approximately unchanged. Initialization moves into the first actual analysis request; its latency must be assessed with the full workflow.
+
+| Default ripgrep first RPC | Baseline ms | Candidate ms |
+| ------------------------- | ----------: | -----------: |
+| cold                      |       231.5 |       2532.1 |
+| warm                      |       227.1 |       2118.2 |
+
+Within each profile, advertised context remains identical. Input-directory estimates are 49,670 tokens for default compact and 205,744 for full. Whole-task estimates include the supplied question/recipe, server instructions, directory once, every tool argument and text reply, and the prompt directory in discovery tasks. This projection assumes the client retains one unchanged directory; raw catalog result costs count every observed list result separately, including output schemas. These use tiktoken 0.14.0/cl100k_base; actual model usage, reasoning and SDK initialization/framing are unmeasured.
+
+Linux x64 / AMD EPYC 7B12 / kernel 6.1.0-54-cloud-amd64 / Node 24.18.0, npm 11.16.0. Timed SDK tasks negotiated the legacy protocol era; auto/modern correctness is covered separately by compiled boundary tests. Trials run serially under a 1-CPU quota pinned to CPU 15, 4 GiB hard memory / 3 GiB early stop, no swap and 192 tasks. No resource stop, OOM or remaining payload process was observed. Cold disables server Node compile cache; warm uses a role/profile-specific cache populated by one complete task. Fresh processes and HOME are used each trial. Cache hit rate and OS page cache are unmeasured. Runtime audits warm compiled-file pages and are included in whole-task costs. Builds, downloads, oracle generation and cache priming are preparation outside those costs. Retained V8 heap and forced-GC measurements were not separately collected.
+
+## Ownership and validation
+
+`OwnedMcpServers` seals publication before taking its close snapshot, keeps failed exact close capabilities for retry and serves both eager and deferred paths. Deferred startup still joins servers published before an asynchronous serving handle settles. Post-snapshot and post-close factory calls are refused before allocation. Both production-boundary regressions fail with only the shared guard removed and pass restored.
+
+The moved transport/delivery implementation preserves current complete-error retention, escaped-preview fitting, response/string-limit recovery, target-content provenance and native Evidence continuations. Canonical parsers remain authoritative after lazy binding. Both protocol eras, input/output profile choices, invalid input/output, completion cancellation, partial startup and cleanup retry are exercised.
+
+Aggregation keeps catalog, producer-script and guard-script digests in distinct variables. Before publishing a trial it verifies that the catalog digest matches both its catalog-file receipt and the shared profile identity. Deliberately selecting the guard digest for that field is rejected. Regeneration preserves all measured timing, CPU, memory, context and parent-Evidence values.
+
+Executed local gates: 125 focused tests across 14 files; a repeated 22-case schema/profile subset after the pinned main merge; all six static-check tasks plus architecture guards; builds for both pinned runtimes; six documentation checks and five README consistency tests. HTTP coverage includes the real compiled CLI session/replacement/Host tests. Runtime-binding admission rejects a mismatched compiled graph before MCP launch; aggregation rejects a tampered trial binding. The raw receipts remain in `/tmp/rea-perf-mcp-startup-20261022`, identified by hashes in the data. Real initial-target providers, foreign OS runtime behavior and other providers remain outside this measurement.
+
+## Reproduction
+
+Use the pinned Node/npm toolchain and separate clean baseline/candidate checkouts. Build each with `npm ci` and `npm run build:cached` (the measured workspace shared one locked dependency installation). Acquire and verify the official packages listed in the data, extract the named executables and generate independent oracles with `mcp-input-catalog-oracle.py`.
+
+Capture each checkout with `node experiments/analysis-efficiency/managed-cli-runtime.mjs CHECKOUT mcp`. Construct `measurement-inputs.json` using the recorded schema, updating absolute checkout/artifact/oracle paths and their independently verified bindings. Keep it immutable through a cohort; producer source digests cover `mcp-input-catalog.mjs`, `managed-cli-runtime.mjs`, `resource-run.py` and `resource_payload.py`.
+
+Run `mcp-input-catalog.mjs` through `resource-run.py --observe-payload-exit` with `--runtime`, `--output`, `--bindings`, `--role baseline|candidate`, `--profile default|full`, `--phase discovery|analysis` and `--cache cold|warm`. Analysis also takes `--artifact` and `--oracle`; warm requires a role/profile-specific `--cache-root`. Disable the driver compile cache for both cohorts. Prime each warm role/profile once with the complete ripgrep task. Follow the 72-case order in the data, reversing role order in every second pair. Aggregate with `python mcp-startup-costs.py LAB --output mcp-startup.json` using tiktoken 0.14.0. The aggregator verifies every input/runtime/guard binding and completed receipt before producing summaries.
