layers: drop the move tool's --layer, move the runtime manager service, and slim Domain tonic - #1471
Three small follow-ups to the layer move (#1367, #1368), one commit each:
scripts/move_crates.py drops --layer. Applying the move one layer at a
time leaves a mixed brace path such as crates/{libs,l40_api}/fam/** that --verify's prefix search can't see. The real move used the one-shot path,
so --apply and --verify now always take every mapping row; a re-run on a
moved tree finds nothing to move.
pplx-space-runtime-manager-svc moves and is renamed pplx-space-node-runtime-manager-svc (binary unchanged, space-rtmgr-svc), now at crates/l50_app/node/runtime/manager/svc. It was
the one crate the move left: it enabled pplx-space-node-runtime-manager/s3,
a driver feature baselined in [layers.codec_features]. That feature only
let the API crate be built without its S3 kernel source, and its one user,
the shipped binary, always enabled it, so the API crate now depends on aws-sdk-s3 and pplx-space-s3-http-client unconditionally (its existing [layers.storage_access] entry already names both) and the feature is gone.
The tool generated the move and rename. The codec_features entry and the
crate's unmoved entry are removed; none is added. crates/apps now holds no
crate, so the README layout and the Rust error-handling and tracing
conventions stop naming it as a home for crates.
Three Domain crates build tonic without its transport. pplx-space-api-route reads only tonic::metadata, and pplx-space-execution-common and pplx-space-credential-injection-core only include_proto! protos without services, so they now use default-features = false and their own trees drop hyper, h2, axum and
tower (cargo tree -i hyper finds none for them; with the pinned Cargo, a
member's default-features = false on the plain inherited tonic = "0.14"
is honoured, without a warning). The other Domain crates on tonic keep its
defaults: their protos declare services whose generated clients use tonic::transport::Channel.
The move tool's tests: 18 passed. move_crates.py --verify passes.
cargo nextest for node-runtime-manager, the renamed svc, api-route,
execution-common and credential-injection-core (ignored tests included):
115 passed.
cargo tree -e normal,build with resolved features: the shipped runtime
manager binary differs only by the package rename and the removed feature
name (with and without otel,datadog); for the tonic change, identical
before and after for the workspace and each of the 36 packages with a binary.
cargo arch and the README's "check a branch as CI does" recipe against
main: exit 0, no findings.
The release Dockerfile stages that name the renamed package resolve as cargo check with the same flags.
Severity and risk
Severity: does not apply; no behaviour change.
Risk: low. Builds of pplx-space-node-runtime-manager without the old s3
feature now compile the S3 client too. Open pull requests that edit the
runtime manager service move with it on a local rebase. Roll back by
reverting.

Walkthrough
The runtime manager service moves to crates/l50_app/node/runtime/manager/svc and takes a new package name. The server’s S3 source is available without an s3 feature gate. The crate-move script applies and verifies all mapped moves in one run, and its tests cover reapplying a completed move and resuming a partial move. Three domain crates disable tonic default features. Build commands and repository documentation reflect the package move.

Merge Risk: Moderate · up to 3154d
Restore the partial-move verification test before merging so regressions in detecting misplaced crates are caught.
Security architecture risk: Low · up to 3154d
The shipped service retains its existing S3 behavior and executable name. No introduced authority expansion was established. Remaining uncertainty concerns external consumers of the renamed package and production rollout configuration.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The demonstrated expansion is S3 capability in library builds that previously omitted the feature, not new S3 authority in the shipped service. The inspected caller and unchanged client do not establish increased tenant, datastore, credential, or environment exposure. Out-of-repository consumers remain outside this assessment.
Trust Boundaries and Controls
observed — S3 source construction remains an explicit configuration choice: KernelSourceConfig::S3 converts its supplied URI into the S3 client, while Custom retains the deployment-supplied source. Removing conditional compilation does not itself select S3 for every library consumer.
Resilience and Maintainability Implications
observed — The existing S3 listing path retains a connection timeout, a 30-second whole-listing timeout, and a 2,000-object limit. These failure-containment controls remain in the implementation now compiled unconditionally.

Explanation
PASS: This pull request does not fix an application-behavior defect. The changed crate source only removes feature gates around the existing S3 source, while the service source is moved unchanged. The other changes update dependency features, crate paths, and the move tool. The check therefore does not require a regression test.
Full details: Weakened Safeguards Are Justified
Explanation
No unjustified safeguard weakening is introduced. The removed layer-specific test is replaced by tests for completed-move reruns and partial-move resumption in scripts/tests/test_move_crates.py:474-528, including assertions for paths, renames, dependency rewrites, cargo check, and --verify. The unmoved and architecture-baseline entries are removed because the runtime manager crate moved and its s3 feature was removed, as explained in the PR description. No lint, CI test step, allowlist, or known-failure exception is weakened.

Restore coverage for committed partial-tree resumption.
The current test covers only a completed move followed by a no-op run. It does not detect a regression that leaves a committed partial tree unfinished. Keep a test that creates a valid committed partial move, then runs the current --apply and asserts that the remaining paths move and cargo_check succeeds. Adapt the setup to the current interface instead of restoring the removed --layer flag.

Included review availability: This review used your included allowance. Your plan provides up to 12 included reviews per hour; 5 remain after this review.
Applying the move one layer at a time leaves a directory of crates split
between an old root and a layer directory, which the rewrite names with a
mixed brace path such as `crates/{libs,l40_api}/fam/**`. --verify looks
for old paths with a plain prefix search, so it cannot see one, and a
later layer's run does not rewrite it either. The real move used the
one-shot path, so remove --layer from --apply and --verify instead of
teaching both about mixed globs.
--apply and --verify now always take every row of the mapping. A row
stays keyed by the name it was reviewed under, so a later run on a moved
tree still finds renamed crates by their new names; the layer-by-layer
test becomes one that re-runs --apply after a full move and finds
nothing left to move.
… move it
pplx-space-runtime-manager-svc enabled the `s3` feature of
pplx-space-node-runtime-manager, a feature that turns on the crate's
optional aws-sdk-s3 and pplx-space-s3-http-client dependencies. That is a
driver feature, which only stores and storage helpers may enable, so the
edge sat in `[layers.codec_features]`; the table is keyed by package, so
renaming the App would have read as a new entry, and the crate move left
it in place.
The feature only let a build of the API crate leave out its built-in S3
kernel source. Its one consumer, the shipped binary, always enables it
and always selects `KernelSourceConfig::S3`, so which kernel sources the
runtime manager can read is the API crate's choice, not the App's. The
API crate now depends on both crates unconditionally and the `s3`
feature is gone. Its existing `[layers.storage_access]` entry already
names both dependencies, so no entry is added. The binary builds the
same: `cargo tree -e normal,build` for the package, with and without
otel,datadog, differs only in the removed feature name.
With the edge gone, `stale_entries` asked for the codec_features entry,
which is removed. The mapping row changes from "stay" to the rename, and
`scripts/move_crates.py --apply` moved the crate to
crates/l50_app/node/runtime/manager/svc as
pplx-space-node-runtime-manager-svc, dropped its `unmoved` entry, and
rewrote the workspace member, Cargo.lock and the release Dockerfiles'
feature flags. The binary keeps its name, space-rtmgr-svc.
The crate was the last one under crates/apps, which now holds no crate, so
the README layout and the Rust error-handling and tracing conventions stop
naming it as a home for crates.
pplx-space-api-route, pplx-space-execution-common and
pplx-space-credential-injection-core took tonic's default features,
`transport`, `router` and `codegen`, which pull in hyper, h2, axum, tower
and tokio's net runtime. None of them uses those: api-route reads
`tonic::metadata`, and the other two only `tonic::include_proto!` protos
that declare no service, so the generated code is prost messages alone.
They now depend on tonic with `default-features = false`, and their own
dependency trees lose hyper, h2, axum and tower.
Every binary builds the same: `cargo tree -e normal,build` with resolved
features is identical before and after for the workspace and for each of
the 36 packages with a binary, since each also depends on tonic with its
transport through another crate.
The other Domain crates on tonic keep its defaults: their protos declare
services, whose generated clients include `connect` on
`tonic::transport::Channel`, and spaced-common and
credential-provider-proto call `tonic::transport` themselves.
Dropping --layer left only a test that re-runs --apply after a full move,
which stops at "nothing to move" before the resume path does any work.
The new test moves the synthetic workspace with one crate held back,
then flips its row to move and rename it: the second --apply moves only
that crate, finds the crate the first run renamed by its new name without
renaming it again, keeps the file rows the first run moved, and rewrites
the references to the newly moved crate; --verify against the commit
before it passes.
Assert the old-path diagnostic with an unchanged package name.
The current fixture renames pplx-space-widget, so --verify can report packages differ even if the crate-location check is removed. First change the deferred row to its target without a rename, verify against the generated-mapping commit, and assert the old-path diagnostic. Then add the rename and keep the existing resume assertions.
