- Around line 4558-4559: Update the documentation around
from_path_with_policy_and_env to state that it uses EnvAccessPolicy::default(),
replacing the description that it uses a selected policy; keep the surrounding
reader-borrowing and explicit-loader behavior unchanged.
In `@docs/users-guide.md`:
- Around line 1751-1752: Update the vector environment-value documentation to
state that ortho_config accepts both comma-separated values and serialized JSON
arrays. Apply this wording in docs/users-guide.md at lines 1751-1752 and
docs/v0-1-0-migration-guide.md at lines 360-362; both sites require the same
documentation change.
In `@src/cli_l10n_flag_keys.rs`:
- Line 3: Update the intra-doc link in the module-level documentation to
reference crate::cli_l10n instead of super::cli_l10n, leaving the surrounding
documentation unchanged.
In `@src/manifest/path_loaders.rs`:
- Line 21: Update the documentation for the from_path loader to state that it
can fail when the file cannot be read, the template cannot be rendered, or the
YAML cannot be parsed, reflecting failures propagated from the environment-aware
loader.

Keep the environment-policy remediation record aligned with the repository’s en-GB documentation standard.
Use the repository’s Oxford spelling in the audit and the established Dutch technical term for the Jinja environment helper.
Express the configuration-layer matrix as reusable test data so the precedence test remains readable and satisfies the CodeScene method-size rule without changing its coverage.
Prove that a project block rule overrides an operator allow rule, and align the Russian environment helper description with the block flag.
Describe list-valued configuration sources, migration behaviour, and the manifest environment ownership and enforcement boundary for contributors.
Add the required documented-example marker so the guide configuration fence is included in the documentation checks.
Add the required documented-example marker so the serialized environment configuration fence is included in the guide checks.
Add the required documented-example marker so the repeated environment policy flags are covered by the guide checks.
Keep the documented-example registry aligned with the three newly marked environment policy examples.
Apply Windows environment-name semantics to policy matching and keep the policy domain free of localized presentation data. Cover unlisted active allowlist lookups so blocked readers, names, and values remain unreachable.
Keep the established path-loader adapters permissive and expose a separate ManifestEnvironment entry point for policy-aware callers. Preserve JSON-mode reporting for malformed project environment policy and compile-check both public loader surfaces.
Drive the matching allowlist entry from operator environment configuration so the regression test proves a project block rule still takes precedence.
Share platform-normalized policy insertion and denied-lookup assertions to keep the access-control boundary clear and satisfy the CodeScene health gate.
Drop the compile-only loader results explicitly so the external API fixture remains clear under strict must-use linting.
Register `manifest_environment_embedder_fixture_compiles` with the `nested-cargo-builds` Nextest group. It consumes `compile_public_api_fixture`, which reaches `NetsukeRlib::build()`, so it spawns a child Cargo build and must not run beside the other build-capable fixtures on a four-vCPU coverage runner. `tests/workflow_contracts/nextest_child_cargo_group_test.py` discovers that reachability and fails the contract until the override names the test.
`make lint` failed in `lint-whitaker` because three modules exceeded the 400-line `module-max-lines` boundary after this branch's additions: - `src/cli/config.rs` (405 lines) — extracted the post-merge validation helpers into `src/cli/config_validation.rs`, following the existing `manifest_budget_config.rs` precedent. - `src/cli_l10n.rs` (401 lines) — extracted the Clap argument-identifier-to-localization-key lookup tables into `src/cli_l10n_flag_keys.rs`. - `src/manifest/mod.rs` (446 lines) — extracted the `from_path*` loader family and its compatibility adapters into `src/manifest/path_loaders.rs`, re-exported so the public API is unchanged. Each extraction keeps the moved items' visibility and behaviour identical; the loader chain, the `NO_INPUT_VALIDATION_REASON` constant, and every existing entry point remain where their consumers already reach them.
Add ADR-026 to record why project environment policy stays below the operator ceiling: the exact-name allow and block rule, the primary-project quarantine, and enforcement before the reader runs. Drop the stale `assertion_line` key from the release-help metadata snapshot so it stops churning on unrelated edits, and extend the compile-pass UI fixture to type-check the new public `from_str_with_env_and_policy` entry point alongside the existing loader adapters.
Hold the exact-match rule with near-miss policy cases: an allowlist entry for `CI` must not admit `CI_EXTRA`, and a `GITHUB_TOKEN` block must not reach `GITHUB_TOKEN_EXTRA` or `TOKEN`. Prefix semantics satisfied every previous case, so only these near misses pin the rule. Cover the `generate` policy call site, which is separate from the already-covered `graph` one. A generate-path regression that dropped the CLI policy previously left the whole suite green.
Adding `env_access_policy` pushed two runner loaders past the `too-many-arguments` ceiling, and the previous commit bought compliance with an `#[expect]` on each. That defeats the point of the ceiling: `clippy.toml` sets it to mirror CodeScene's, so suppressing it locally hides exactly the finding the configuration exists to surface. Group the trusted-configuration seams into `ManifestLoadInputs` and let `from_cli` resolve them, the way `manifest::ManifestParse` already bundles the parse path. Both loaders drop from five arguments to three and both expectations come out, so the ceiling is met by shape rather than by silence. Resolving the bundle also collects the network-policy context once, at a single site, instead of at each call site.
Four review findings were verified against the current source before being actioned. Three hold; one does not. The developers guide called the injected reader's policy "the selected policy". It is not selected: `from_path_with_policy_and_env` and its limits sibling pass `EnvAccessPolicy::default()`, which is permissive for compatibility. State that, and point at the environment-aware entry points that do carry the caller's policy. The users guide named fetch-policy fields as the sole exception to ordinary precedence. Primary-project `env_allow_var` entries are removed before policy composition too, so they cannot widen the allowlist or activate default-deny. Readers could otherwise infer that project allow entries override operator configuration. `from_path`'s `# Errors` section omitted template rendering, which reaches it through the environment-aware loader it delegates to. In `cli_l10n_flag_keys.rs`, `[`super::cli_l10n`]` cannot resolve: the file is a `#[path]`-declared child of `cli_l10n.rs`, so `super` already is `cli_l10n` and the link looked for a `cli_l10n::cli_l10n` that does not exist. `cargo doc` runs under `-D warnings` in `make lint`, so this was a live gate failure, not a style nit. Not actioned: the claim that vector environment values also accept comma-separated form. That describes `ortho_config`'s `CsvEnv`, which netsuke never uses — no reference to it exists in `src/`. Netsuke builds its own `EnvironmentLayer` over `figment::value::Value`'s `FromStr`, which parses JSON-shaped text and otherwise falls back to a plain string; it never splits on commas. A probe against the built binary agrees: `NETSUKE_ENV_ALLOW_VAR='PROBE_A,PROBE_B'` leaves the lookup blocked, while the bare `PROBE_A` and the JSON array both succeed. Documenting comma support would therefore be wrong. Gates: make check-fmt, make typecheck, make lint, and make test all pass on this commit.
The pre-merge Observability check is right that the access policy added a new manifest-load failure outcome with nothing operational to measure it. A refusal is the whole point of ADR-026, and the accompanying tracing event is neither aggregated nor retained by the application recorder, so an operator could not answer "how often is the policy refusing?". Count every lookup at the one place a lookup can happen. `env_var_with` in `src/manifest/env_reader.rs` is the registered `env()` boundary, and ADR-026 already places enforcement there, so `env_telemetry::record_env_lookup` composes with all four exits and returns each result unchanged rather than restating the mapping. The series is `netsuke_manifest_env_lookups_total`, labelled by the closed `outcome` vocabulary `success`, `blocked`, `not_present`, and `not_unicode`; `outcome` is a `&'static str` chosen from those constants and a debug assertion holds the call sites to it. Bounded and redacted by construction, not by convention. The variable name and any value it resolved to never reach a label: names routinely identify credentials and a permitted value can carry secret material. `ConfigMetricsRecorder` admits exactly that one-label series, so a foreign label name, an extra label, or an out-of-vocabulary value stays unretained instead of entering the shutdown snapshot. The docs keep pace: ADR-009 gains the boundary as a third addendum alongside the template-render and runner-structure ones, and the design, user, and developer guides name the counter and what it does not carry. `from_path_with_policy`'s `# Errors` section omitted parsing, which it reaches through the loader it delegates to; it now names read, render, and parse. The inline finding also asked for a "Triage:" tag on the comment. There is no such convention for rustdoc `# Errors` sections in this repository — `Triage:` appears once, as a bolded marker in the users-guide JSON-schema section for consumers — so adding it to a function's error documentation would invent a convention rather than follow one. Gates: make check-fmt, make lint, make typecheck, and make test all pass, with the new telemetry cases and the recorder retention case confirmed executed rather than skipped.

@coderabbitai The Observability warning is now implemented, not just planned. The counter landed in commit aa7e5b38 ( Production-visible and bounded. Registered and admitted. No names or values in labels. The variable name and the value it resolved to are absent by construction. Environment variable names routinely identify credentials, and a permitted value can carry secret material; the accompanying trace event already carried only the bounded Tests added, and confirmed executed.
