feat: default telemetry to user-only

[iamclaude697]

Summary

Phase 15a.1: telemetry defaults to user-only. A default chaffra run collects user-facing summary metrics only and cannot emit operator telemetry (per-module latencies, error/startup/connection counters, plugin errors, parse-cache memory data, module timing spans, and operator-shaped backend/sampling config metadata). Operator metrics become an explicit opt-in via --telemetry on|operator-only or [modules.telemetry] audience in .chaffra.toml.

Behavior change + GDPR rationale

Operator metrics describe process and environment shape that can characterize an operator or environment. Under GDPR data-minimization (Art. 5(1)(c)), such operational metadata should not be collected or forwarded without explicit justification. Defaulting to user-only makes operator emission an explicit, auditable opt-in.

The privacy boundary has two halves: (1) the metric payload is scrubbed by TelemetrySnapshot::project_for_audience → ProjectedSnapshot (the type-level guard); (2) operator-shaped config/status metadata (backend kind / endpoint / port / namespace / connectivity, and the sampling emission policy) is gated by audience at every boundary that would disclose it. Raw operator-only fields — payload or metadata — never cross a user-facing boundary.

Precedence

--telemetry (explicit) > [modules.telemetry] audience (file) > default (user-only). A checked-in .chaffra.toml cannot widen a narrower CLI choice. The same precedence rule governs the backend selector: --telemetry-backend / --telemetry-endpoint > file backend > default (cli_backend_override marks the explicit CLI choice; R10-F1). The MCP chaffra/telemetry tool ALWAYS runs at the project's resolved audience — no caller-supplied widening (R5-2); the only externally reachable telemetry entry point is execute_telemetry (config-taking helper is pub(crate), R6).

Fail-closed config (single shared path)

from_module_config is the one config-loading path shared by CLI, telemetry module, and MCP tool. Every present-but-invalid [modules.telemetry] value fails closed with a typed error:

• audience → InvalidAudience (R4-F1). Only the four documented string modes (+ snake_case user_only/operator_only) parse; the true/1/false/0 aliases are rejected so a stringified non-string TOML value (audience = true / audience = 1) cannot become an operator opt-in (R9-F3), and the undocumented bare user/operator aliases are rejected so audience = "operator" fails closed (R10-F3).
• backend → InvalidBackendConfig via typed BackendKind::parse (R7-F1).
• sampling-rate → InvalidSamplingConfig for non-numeric and non-finite (NaN/inf/-inf); finite out-of-range is clamped (self-audit + R7-F2).
• sampling-strategy → InvalidSamplingConfig (self-audit).
• Both spellings of each sampling key are validated when present, so a present invalid alternate spelling fails closed instead of being short-circuited past (R9-F4).

The same typed parsers back --telemetry / --telemetry-backend (build_telemetry_config returns Result, no lenient fallback). Implicit .chaffra.toml discovery uses Path::try_exists(). MCP resolves project config through the same strict load_from_dir path, and chaffra management resolves through the same resolve_subcommand_telemetry path the live runs and diagnostics use (R11-F1) — there is no command that constructs telemetry config off a separate, lenient path.

File backend honoured on live CLI runs (R10-F1)

merge_telemetry_config now applies the file [modules.telemetry] backend on live CLI runs when no explicit CLI backend selector was given, so a checked-in backend = "stderr" actually takes effect instead of being silently dropped for the default JSON-file sink (the MCP/module path already honoured it via from_module_config; the live CLI path did not). An explicit --telemetry-backend / --telemetry-endpoint still wins, carried by the cli_backend_override precedence marker (#[serde(skip)], the backend twin of cli_audience_override). The file backend's endpoint / path travel with the kind, matching from_module_config.

Hardened scope classification

Metric NAME + data point PROVENANCE. Shared metric_names::OPERATOR / KNOWN_USER sets; three-way fail-closed classification (unclassified admitted only under On). Provenance overrides name: every external gRPC ingress routes through an untrusted entry point — data points (record_untrusted_data_points, R3-3), definitions (register_untrusted_metrics, R4-2), spans (record_untrusted_spans, R5-1) — recording the name in untrusted_runtime (#[serde(skip)]); projection forces any such name to the unclassified branch. test_every_core_metric_is_classified fails CI on any unclassified registered metric.

Projection enforced at the type level (R5-Structural)

project_for_audience(self, audience) -> ProjectedSnapshot; the only constructor is project_for_audience, no DerefMut, no Deserialize (R9-F2: deriving it would be a serde constructor that wraps raw unprojected input), the inner tuple field is private (R12-F1: a pub(crate) field left the ProjectedSnapshot(raw) constructor reachable from within chaffra-telemetry itself, where the output boundaries live — now no module, in or out of the crate, can wrap an unprojected snapshot), and TelemetryBackend::flush/inspect accept &ProjectedSnapshot. Forgetting to project the payload at an output boundary is a compile error. #[serde(transparent)] + Serialize-only keeps the on-disk/wire shape byte-identical (the inner TelemetrySnapshot keeps Deserialize); in-crate serialization reads via inner(), external callers via Deref.

Audience-gated operator metadata (operator-shaped)

Backend kind / endpoint / port / namespace / connectivity and the sampling emission policy are operator-shaped config/status metadata that ProjectedSnapshot does not scrub, so every boundary that would disclose them gates on the operator scope (On / OperatorOnly):

• TelemetryModule::analyze backend-status finding (R4-1).

• MCP chaffra/telemetry status / backends (R4-3).

• CLI chaffra telemetry status / test / inspect (R7-F3, R8-F1) — withhold under user-only/off.

• Live run_with_telemetry / module backend flush() (R9-F1) — the flush log lines are now audience-neutral: otlp/prometheus/cloudwatch route through a flush_log_line(byte_len) helper that cannot reference the endpoint/port/namespace, so a default user-only run discloses no backend metadata on stderr. The values remain on the operator-gated test_connection / inspect surfaces.

• chaffra-management HTTP server (R10-F2 + round-11/13 follow-ups) — chaffra management builds its collector from the resolved telemetry config (default user-only), and is now gated on three axes:

  • Backend + sampling metadata (/api/v1/metrics, /api/v1/config): backend kind/connected/message and backend kinds, and the sampling configuration (sampling_rate / sampling_strategy on /config, R13) are operator-shaped config metadata describing the operator-telemetry emission policy (not snapshot payload, so project_for_audience does not scrub them), gated on audience.operator_enabled() → backend lists empty and sampling fields null under user-only/off. The audience mode itself is always reported.
  • Snapshot payload (every snapshot-reading handler: metrics, modules, findings/summary, findings/churn, health): routed through project_for_audience(config.audience) — the same type-level guard the CLI/MCP/flush paths use — so under user-only operator data points are scrubbed, per-module duration_ms (the operator chaffra.module.call_duration_ms) is zeroed, and the operator-error-derived module status is withheld. Management was the one output boundary still reading the raw snapshot; it no longer is.
  • Config source (R11-F1): chaffra management resolves its telemetry config through the same resolve_subcommand_telemetry → load_config + merge_telemetry_config path as live runs and the diagnostics, so a checked-in [modules.telemetry] audience/backend governs the management collector (an explicit CLI flag still wins) and a malformed [modules.telemetry] fails closed before the server binds. No parallel config path remains.

  Only the co-located live-collector / history integration remains deferred (Stage 15a.3).

Audience-gated emission / audit

run_with_telemetry calls maybe_audit_log_audience at the live boundary. On/OperatorOnly → TelemetryEnabled; UserOnly → TelemetryDisabled; Off writes NO audit event (R5-Audit-Off).

Deferred (with anchors)

Per-point source-tagging at the producer is the durable structural fix (issue #45); untrusted_runtime provenance is the bounded mitigation, TODO(#45) anchored at every metric-side seam. cli_audience_override threading tracked as chaffra#50. The chaffra-management API now audience-projects its snapshot-derived outputs and gates its operator-shaped config metadata (backends + sampling) through the shared path (rounds 11/13); the remaining deferral is the co-located live-collector / history integration (Stage 15a.3) — /api/v1/metrics/history returns not_implemented until then, and under operator-only the user-scoped /modules and /health views are empty (the fail-safe under-disclosure direction), revisited when the operator-summary-sourced views land in 15a.3.

Migration notes

• Default audience on → user-only.
• Invalid --telemetry / --telemetry-backend / [modules.telemetry] values are hard errors; audience accepts only the four documented string modes (on/off/user-only/operator-only) plus snake_case user_only/operator_only — true/1 and bare user/operator are rejected. Malformed/inaccessible .chaffra.toml fails closed everywhere, including chaffra management.
• A file [modules.telemetry] backend now takes effect on live CLI runs when no --telemetry-backend/--telemetry-endpoint is given (R10-F1); an explicit CLI backend still wins. The same file audience/backend now also governs chaffra management (R11-F1).
• Backend metadata is operator-gated at the backend-status finding, MCP status/backends, all three CLI diagnostics, the live flush log, AND the chaffra-management /api/v1/metrics + /api/v1/config endpoints; the management snapshot-derived outputs are audience-projected. Tests/clients relying on operator output (backends or operator data points) must set an operator audience.
• The chaffra-management /api/v1/config sampling fields are operator-gated (R13): ConfigResponse.sampling_rate / sampling_strategy are now nullable and are null under user-only/off, populated only under an operator audience. Clients consuming /config must treat these two fields as optional (the audience and backends fields are unchanged in shape).
• MCP chaffra/telemetry schema has NO audience parameter (R5-2); accepts optional path (R4-F1).
• TelemetryBackend::flush/inspect take &ProjectedSnapshot; ProjectedSnapshot is Serialize-only with a private inner field (R12-F1).
• No on-disk format, metric names, backend payloads, or gRPC schema changed. .chaffra-telemetry-audit.log gitignored.

Round-10 re-review fix (52f2f9e)

#	Severity	Site	Fix
R10-F1	HIGH	chaffra-cli/src/main.rs::merge_telemetry_config	File [modules.telemetry] backend was ignored on live CLI runs — the merge copied audience/sampling but not backends, so backend = "stderr" kept the default JSON-file sink while the MCP/module path honoured it. Added a cli_backend_override precedence marker (set in build_telemetry_config when --telemetry-backend or --telemetry-endpoint is given) and apply project_tel.backends when !cli_backend_override && contains_key("backend"). Precedence: CLI backend > file backend > default. Tests assert the marker (true / false / endpoint-only) and the merge in both directions.
R10-F2	HIGH	chaffra-management/src/api.rs /api/v1/metrics + /api/v1/config	Both endpoints returned operator-shaped backend metadata (kind/connected/message; backend kinds) unconditionally, and chaffra management builds its collector at the default user-only. Gated both on state.collector.config().audience.operator_enabled() → empty under user-only/off, populated under operator. (Extended in the round-11 follow-up to also project the snapshot payload, and round-13 to gate the sampling fields.)
R10-F3	MEDIUM	chaffra-telemetry/src/config.rs::TelemetryAudience::from_str_loose	Accepted undocumented bare user/operator aliases, so audience = "operator" silently enabled operator emission. Removed them (kept the four kebab modes + user_only/operator_only); audience = "operator" now fails closed via parse. Assertions added beside the bool/int rejection tests and test_from_module_config_non_string_audience_fails_closed; doc comment corrected.
R10-F4	MEDIUM	chaffra-mcp/Cargo.toml tempfile = "3" (dev-dep)	Dependency-gate evidence (see Verification). tempfile = "3" is an existing, ubiquitous workspace dev-dependency — already a direct dev-dep of 7 other crates (monorepo, autofix, migrate, management, cli, telemetry, impact). Dual MIT OR Apache-2.0, test-only, adds no new transitive surface to the workspace.
R10-F5	MEDIUM	PR body	Verification refreshed to the full new head SHA with exact command exit results and the named coverage artifact (this section + below).

Round-11 follow-up — management snapshot projection (feed762)

A further independent adversarial pass (repo-owner persona + completeness critic, double diverse-skeptic verification) found that chaffra-management was the one output boundary still reading the raw collector.snapshot() — so under the new user-only default it disclosed operator data beyond the backend metadata R10-F2 gated: get_modules exposed per-module duration_ms (the operator chaffra.module.call_duration_ms) and an error-derived status (from operator_summary.module_error_counts), and get_metrics surfaced operator data-point names. This is the same class as R10-F2.

Fix: route every snapshot-reading handler (get_metrics, get_modules, get_findings_summary, get_findings_churn, get_health) through the existing project_for_audience type-level guard, closing the leak with the PR's own structural mechanism rather than a hand-rolled per-field filter. User-facing metrics (finding counts, churn, health_score) are KNOWN_USER and survive user-only. Backend metadata keeps its separate operator_enabled() gate. New tests assert operator data points and per-module timing/status are scrubbed under user-only and present under an operator audience; docs (management.md, telemetry.md) and chaffra management --help were reconciled.

Round-11 reviewer re-review fix (8ec34c1)

#	Severity	Site	Fix
R11-F1	HIGH	chaffra-cli/src/main.rs::Command::Management	chaffra management built its collector straight from the CLI-derived tel_config, bypassing resolve_subcommand_telemetry (load_config + merge_telemetry_config). A project's [modules.telemetry] audience/backend was ignored for management and a malformed [modules.telemetry] did not stop startup — a parallel config path Stage 15a.1 forbids. Now routed through the shared resolver via build_management_collector / build_management_collector_in: a checked-in audience/backend governs the management collector, an explicit CLI flag still wins, and a malformed file fails closed before the server binds. Tests cover file audience, file backend, CLI-override precedence, malformed-fail-closed, and the cwd wrapper.
R11-F2	LOW	docs/api/management.md /modules, /health	The audience tables documented user-only/on/operator-only but omitted off. Both endpoints are user-summary-sourced, so off (like operator-only) yields an empty module list / null health. Documented off for both, completing four-mode coverage.

Round-12 reviewer re-review fix (d804bf3)

#	Severity	Site	Fix
R12-F1	MEDIUM	chaffra-telemetry/src/collector.rs::ProjectedSnapshot	The newtype's tuple field was pub(crate), so any module inside chaffra-telemetry — the crate that owns the backend flush/inspect and module output boundaries — could construct ProjectedSnapshot(raw_snapshot) directly, bypassing project_for_audience and satisfying TelemetryBackend::flush/inspect with an unprojected snapshot. Made the field fully private: project_for_audience (same module) remains the sole constructor; in-crate serialization reads via the pub(crate) inner() accessor and external callers via the public Deref. No ProjectedSnapshot(raw) constructor is reachable from anywhere now. Doc comment updated.

Round-13 fix — sampling config gate (f2b0be8) + doc reconcile (48e8ae4)

Found by the mandated independent adversarial pass (the next structural sibling of R10-F2, before the reviewer): GET /api/v1/config gated only the backends field; the sibling sampling_rate / sampling_strategy fields of the same ConfigResponse were still serialized unconditionally, disclosing the operator-telemetry emission policy under the default user-only audience (via the API and the dashboard).

#	Severity	Site	Fix
R13-F1	HIGH	chaffra-management/src/api.rs::get_config (+ ConfigResponse, dashboard_html.rs)	Sampling configuration is operator-shaped config metadata by the project's own classification (the telemetry sampling-status rule reports "operator telemetry sampling configuration"); like backends it lives in TelemetryConfig, not the snapshot payload, so project_for_audience does not scrub it. Gated sampling_rate / sampling_strategy on audience.operator_enabled(): ConfigResponse fields are now Option (null = withheld under user-only/off, populated under on/operator-only); the audience mode is still always reported. Dashboard JS renders the withheld case and no longer mis-fires the <1.0 sampling insight on a null value. Docs (management.md, and the telemetry.md audience-gated-boundary list in 48e8ae4) updated; tests test_config_sampling_withheld_under_user_only / _disclosed_under_operator added. A convergence pass confirmed the gate is complete (no remaining sampling-disclosure site) and that the broader telemetry surface has no further operator-data-under-user-only sibling; a full documentation sweep (all docs/*.md, CLI --help, README, mcp-tools.md) confirmed no remaining drift.

Dependency gate (R10-F4): tempfile = "3" is a dev-dependency of chaffra-mcp (test-only; not shipped in any binary). It is already a direct dev-dependency of 7 other workspace crates — chaffra-monorepo, chaffra-autofix, chaffra-migrate, chaffra-management, chaffra-cli, chaffra-telemetry, chaffra-impact — so it introduces no new dependency or transitive surface to the workspace. License: MIT OR Apache-2.0. As an already-vetted, ubiquitous workspace dev-dep it qualifies for the CONTRIBUTING.md existing-dependency rationale rather than a fresh security/license scan.

Findings

1. HIGH crates/chaffra-telemetry/src/module.rs:125 - TelemetryModule::analyze builds the returned metric-summary finding from the raw snapshot before projection. Under user-only, backend JSON is projected, but the module output can still disclose raw per-module timing/module-set information and raw data point/span counts.
2. HIGH crates/chaffra-telemetry/src/collector.rs:150 - unknown metric names fail open as user-facing. The completeness test covers core-registered names, but runtime/external metrics can still cross the user-only boundary unless they happen to be listed in OPERATOR.
3. HIGH crates/chaffra-cli/src/main.rs:349 - live analysis commands still discard malformed implicit .chaffra.toml via unwrap_or_default(), before telemetry config can fail closed.
4. HIGH crates/chaffra-cli/src/main.rs:441 - Stage 15a.1 requires using the Phase 14 audit-log helper or linking an author-created issue; the PR leaves an untracked TODO(issue).
5. HIGH crates/chaffra-cli/src/main.rs:1369 - telemetry test still flushes configured backends when the resolved audience is Off.
6. HIGH crates/chaffra-cli/src/main.rs:1831 - telemetry diagnostic commands ignore global --config, so previews/tests can disagree with the real run.
7. MEDIUM crates/chaffra-cli/src/main.rs:1311 - telemetry status turns config errors into a successful text report instead of a nonzero command failure.
8. MEDIUM PR body - the PR description still contains a generated-by footer, violating the repo's no-AI-attribution rule.

Path to Approval (Action Plan)

1. Project every telemetry module output boundary, not just backend flushes, before constructing returned findings or metadata.
2. Make unclassified metric projection fail closed, or add an explicit durable scope model for registered/runtime metrics so user-only cannot leak unknown operator metrics.
3. Route live analysis commands through a fail-closed config load for telemetry-relevant .chaffra.toml parsing.
4. Thread global --config into telemetry status, telemetry test, and telemetry inspect.
5. Make telemetry test no-op for backend writes when the resolved audience is Off.
6. Replace TODO(issue) with either the Phase 14 audit helper wiring or a concrete author-created issue reference, and update docs accordingly.
7. Make telemetry status return Result<String> and exit nonzero on invalid config.
8. Remove the generated-by footer from the PR description.

Findings

1. HIGH: the wildcard chaffra.module.<id>.<key> user classifier reopens fail-open behavior for external/runtime metrics.
2. HIGH: the strict loader still defaults on implicit .chaffra.toml metadata errors through Path::exists().
3. HIGH: the new span-classification TODO(issue) is not linked to a concrete issue, so the deferral artifact is incomplete.
4. MEDIUM: the PR evidence is stale for the reviewed head; local verification and coverage evidence are still recorded for 14452a5 despite later revision commits through a42b572.

Path to Approval (Action Plan)

1. Restrict user-facing per-module runtime classification so untrusted/external metric names cannot become known-user solely by choosing the chaffra.module.<id>.<key> shape. Keep unknown runtime metrics fail-closed under user-only and operator-only, or derive scope from a trusted producer/registry path.
2. Make implicit .chaffra.toml discovery default only on true NotFound; propagate metadata/read errors as typed config errors so the shared loader is actually fail-closed.
3. Replace the generic TODO(issue) with a concrete issue link, such as TODO(#45): ..., or remove the TODO if there is no deferred work.
4. Update the PR record with current-head verification and baseline-vs-result evidence for a42b5728cfa4cf664d1a7e4c45b2bee41bb83db1, including the coverage result after the final revision commits.

Findings

1. HIGH: TelemetryModule::analyze still emits backend-status findings for every audience before any audience gate.
2. HIGH: external gRPC metric definitions are still registered as trusted definitions, so definition metadata can cross user-only by spoofing known names.
3. HIGH: MCP chaffra/telemetry snapshot still serializes the raw default snapshot instead of the audience-projected snapshot.

Non-blocking observations:

• LOW: internal coverage-checker comments at scripts/coverage_check.py:102 and scripts/coverage_check.py:1002, plus the MCP test file comment at crates/chaffra-mcp/tests/config_fail_closed.rs:7, still describe the old strict LH >= unique-hit-DA invariant after the parser intentionally relaxed LH undercounts.
• LOW: crates/chaffra-mcp/tests/config_fail_closed.rs uses fixed names under the global temp directory; tempfile::TempDir would be more robust under concurrent/sharded test execution.

Path to Approval (Action Plan)

1. Gate or suppress backend-status findings for audiences that must not receive backend/operator details, especially user-only and off, or project backend status into an explicitly user-safe form before returning it.
2. Treat definitions submitted through gRPC register_metrics as untrusted at projection, just as record_metrics data points now are, so external modules cannot publish user-facing definition metadata under user-only by spoofing exact known metric names.
3. Project the MCP chaffra/telemetry snapshot through project_for_audience(config.audience) before serializing it, and cover that output boundary.

Quality gates audit

Gate	Verdict	Notes
Spec compliance	FAIL	One MEDIUM finding remains: MCP chaffra/telemetry has a parallel config path and ignores project [modules.telemetry] audience / malformed config.
Projection before output/backend boundaries	PASS	Backend trait requires ProjectedSnapshot; live CLI success/failure paths share flush_projected; telemetry module and MCP snapshot project before emission.
Default user-only behavior	PASS	Default TelemetryAudience is UserOnly; default live flushes and MCP snapshot withhold operator metrics/definitions/spans.
Explicit operator opt-in	PARTIAL	CLI and telemetry module honor file/CLI audience. MCP chaffra/telemetry does not honor file audience, so project opt-in does not reach that tool.
Fail-closed invalid config	PARTIAL	CLI and MCP health/dead-code fail closed. MCP chaffra/telemetry bypasses project config loading, so malformed .chaffra.toml is not surfaced there.
gRPC untrusted ingress	PASS	Data points, definitions, and spans all route through untrusted provenance methods.
Duplicated / parallel code paths	FAIL	The remaining issue is exactly a parallel config path in MCP telemetry: execute_telemetry constructs TelemetryConfig::default() instead of using the shared strict project config path.
Tests and CI	PASS	CI green; coverage gates pass at current head.
Docs/help	LOW residual risk	A few low stale-documentation mismatches remain; they are not blocking compared with the config bypass.
AI attribution	PASS	iamclaude697 exemption applied; no non-exempt AI attribution found in changed files/commit metadata.

Blocking finding:

ID	Severity	Location	Issue
R4-F1	MEDIUM	crates/chaffra-mcp/src/tools.rs:202	chaffra/telemetry still bypasses the shared strict project config path by constructing TelemetryConfig::default(). A repository with [modules.telemetry] audience = "on" or "operator-only" still gets user-only for MCP status, backends, and snapshot; a malformed .chaffra.toml is also ignored by this tool. Phase 15a.1 requires the project/file audience to be an explicit operator opt-in and requires no alternate/optional config-loading path. Keep the no caller-supplied widening fix, but resolve the project's telemetry config strictly, like the other MCP tools do for project config.

Non-blocking notes:

Severity	Location	Note
LOW	crates/chaffra-telemetry/src/module.rs:226	The metric-summary explanation still says it includes per-module durations and span data, but those are projected away under user-only.
LOW	docs/api/management.md:115	The example uses "audience": "user-only", while the current management API formats the enum as UserOnly. This is a doc/API representation mismatch.
LOW	scripts/tests/test_coverage_check.py:933	The malformed-LCOV test table comment still says LH>=unique hit DA lines, but the parser now intentionally tolerates LH undercounts.

Path to Approval (Action Plan)

1. Update chaffra/telemetry so it resolves the project telemetry config through the same strict path as the rest of the MCP/CLI surfaces, without reintroducing a caller-supplied audience parameter.
2. Add MCP tests proving:
   • [modules.telemetry] audience = "on" / "operator-only" allows operator status, backends, and snapshot output through the tool;
   • default/no config remains user-only;
   • malformed .chaffra.toml fails closed for chaffra/telemetry;
   • an audience request parameter is still ignored and cannot widen.
3. Optionally clean up the LOW stale-doc/comment mismatches.
4. Re-run required CI and keep the coverage artifact current for the new head.

Verdict

REQUEST_CHANGES.

The previous HIGH privacy leaks are resolved, and the structural projection/newtype work closes the repeated output-boundary class. I cannot approve while the MCP telemetry tool still uses a parallel default config path, because that violates the assignment's shared-loader requirement and ignores the explicit file-based operator opt-in for this surface.

• laplaque/chaffra-prompts/01_initialization/coordinator.md

• repository CONTRIBUTING.md

This is Stage 15a.1 only.

Quality gates audit

Gate	Status	Evidence
Default telemetry is UserOnly and operator emission requires explicit opt-in	FAIL	TelemetryAudience::default() is now UserOnly, but the management API still returns backend status/config metadata under a default chaffra management collector.
Shared config-loading path applies [modules.telemetry] consistently	FAIL	merge_telemetry_config parses TelemetryConfig::from_module_config, but only applies sampling fields and audience; file-selected backends are ignored on live CLI runs.
Present-but-invalid config values fail closed	FAIL	TelemetryAudience::from_str_loose still accepts undocumented user and operator aliases; [modules.telemetry] audience = "operator" enables operator telemetry even though the documented accepted modes exclude it.
Projection before output/backend boundaries	PASS with noted blocker class	ProjectedSnapshot is Serialize only and backend flush/inspect take &ProjectedSnapshot; current blocker is metadata disclosure outside the projected payload, not raw snapshot serialization.
Backend metadata gated by operator audience	FAIL	CLI diagnostics, MCP, telemetry module finding, and live backend flush logs are now gated/neutralized, but management /api/v1/metrics and /api/v1/config still expose backend names/kinds/messages under UserOnly.
No later-stage scope	PASS	No gRPC schema, LSP, watch, churn producer, or live-history wiring introduced. Management code itself was not changed, but the PR's default-audience change and docs expose the existing management boundary under the new privacy contract.
Dependencies gate	FAIL	crates/chaffra-mcp/Cargo.toml adds a new direct dev-dependency on tempfile = "3" without PR-body security scan + license check evidence required by CONTRIBUTING.md.

R10-F1 — HIGH — File backend selection from [modules.telemetry] is parsed but never applied to live CLI runs

merge_telemetry_config calls TelemetryConfig::from_module_config(&module_cfg), but then copies only sampling fields and audience from project_tel. It never copies project_tel.backends. That means a project file like:

[modules.telemetry]
audience = "on"
backend = "stderr"

still runs the live CLI path with the CLI/default JSON-file backend unless a separate --telemetry-backend override was passed. MCP and TelemetryModule::analyze do honor from_module_config backends, so the PR no longer has a single shared config-loading path. More importantly, an explicit project backend can be ignored and operator telemetry can be persisted to the default file sink even though the project selected another backend.

Fix direction: carry an explicit CLI backend override marker, then apply file backends from project_tel.backends when no explicit CLI backend override is present, matching the audience precedence pattern. Add a regression that run_with_telemetry/resolved CLI config honors [modules.telemetry] backend = "stderr" and does not keep the default JSON-file backend.

R10-F2 — HIGH — Management API still discloses backend metadata under the default UserOnly audience

chaffra management starts a TelemetryCollector from the global CLI telemetry config; with this PR, omitting --telemetry means that collector is UserOnly. However the management REST API still exposes backend metadata unconditionally:

• crates/chaffra-management/src/api.rs:111-127 calls create_backends(&state.collector.config().backends) and returns backend name, kind, connected, and message from /api/v1/metrics.
• crates/chaffra-management/src/api.rs:258-270 returns backend kinds from /api/v1/config.
• docs/api/management.md:41-43 advertises the default JsonFile backend and message will write to chaffra-telemetry.json; docs/api/management.md:121-125 advertises "audience": "UserOnly" together with "backends": ["JsonFile"].

That is the same operator-shaped backend config/status metadata class gated elsewhere in this PR. A default management server can disclose active backend kind and file-sink message without --telemetry on|operator-only, contradicting the PR's own "backend kind / endpoint / port / namespace / connectivity is operator-shaped" contract.

Fix direction: gate management backend status/config fields on state.collector.config().audience.operator_enabled(), returning empty backend arrays under UserOnly and Off, and update the management docs/API examples accordingly.

R10-F3 — MEDIUM — Undocumented user/operator aliases still bypass the fail-closed audience contract

The PR body, docs, and parser comment say only on, off, user-only, operator-only plus snake_case spellings are accepted. The implementation still accepts user and operator. In particular, [modules.telemetry] audience = "operator" is not a documented accepted mode but still enables OperatorOnly instead of failing closed.

Fix direction: remove the bare user and operator aliases from TelemetryAudience::from_str_loose, and add regression assertions beside the bool/int alias rejection.

R10-F4 — MEDIUM — New direct dev-dependency lacks required dependency-gate evidence

crates/chaffra-mcp/Cargo.toml adds tempfile = "3" as a new direct dev-dependency. CONTRIBUTING.md requires a security scan + license check before adding new dependencies and requires the scan result in the PR body when adding new direct dependencies. I found no PR-body or PR-comment evidence for the tempfile license/security scan or an explicit exemption rationale.

Fix direction: update the PR body with the dependency-gate evidence for tempfile at the current head, including the security scan result and license check result. If the argument is that tempfile was already present transitively or elsewhere in the workspace, document that as part of the rationale rather than leaving the gate unevidenced.

R10-F5 — MEDIUM — Current-head verification evidence is still stale/incomplete

The PR body's verification section still names local head 60bd70469310b53220e3e6b8c82659b43970245c and artifact coverage-60bd70469310b53220e3e6b8c82659b43970245c. The actual reviewed head is fecd5a12bb3c3385b89695fad352739b43fbe533. The later PR comment gives short fecd5a1 and coverage percentages, but it does not provide the full current SHA, the named current artifact coverage-fecd5a12bb3c3385b89695fad352739b43fbe533, or the exact command/result evidence required by the Stage 15a review gate.

Fix direction: update the PR body, or add an unambiguous current-head evidence comment, with the full head SHA, exact verification commands and exit results, the current coverage artifact name, and the coverage gate results for fecd5a12bb3c3385b89695fad352739b43fbe533.

Path to Approval (Action Plan)

1. Apply [modules.telemetry] backend config to the live CLI resolved telemetry config when no explicit CLI backend override was provided; add regression coverage for file backend precedence.
2. Gate management API backend status/config metadata on operator_enabled() and update management docs/examples for UserOnly/Off.
3. Remove the undocumented user and operator audience aliases; add fail-closed regression tests.
4. Add the missing dependency-gate evidence for tempfile = "3" to the PR body or a current-head PR comment.
5. Refresh the verification evidence to the exact current head, including full SHA, exact commands/results, and the coverage-fecd5a12bb3c3385b89695fad352739b43fbe533 artifact name.
6. Rerun required CI and coverage after the code changes.

@laplaque R10 addressed in 52f2f9e (re-requested review). All five findings:

• R10-F1 (HIGH) — merge_telemetry_config now applies the file [modules.telemetry] backend on live CLI runs; added the cli_backend_override precedence marker so --telemetry-backend/--telemetry-endpoint > file backend > default, bringing the live CLI path in line with the MCP/module path.
• R10-F2 (HIGH) — chaffra-management /api/v1/metrics and /api/v1/config now gate backend metadata on audience.operator_enabled(); the default user-only discloses an empty backends list. Scope limited to the existing disclosure (no 15a.3 live-state wiring).
• R10-F3 (MEDIUM) — dropped the undocumented bare user/operator audience aliases; audience = "operator" now fails closed.
• R10-F4 (MEDIUM) — dependency-gate evidence in the PR body: tempfile = "3" is a dev-dep already used directly by 7 other workspace crates (MIT OR Apache-2.0, no new transitive surface).
• R10-F5 (MEDIUM) — Verification refreshed to full head 52f2f9ecaa1e9babd670d66a33892724bb08ad49 with per-command exit results and artifact coverage-52f2f9ecaa1e9babd670d66a33892724bb08ad49.

Gates (each by its own exit code): cargo fmt -- --check, cargo clippy -- -D warnings, cargo test --workspace, cargo check --workspace --tests all exit 0. Coverage: overall 94.37%, aggregate_changed 100.00% (2262/2262), per_file_changed 100.00%, trust_boundary_changed 100.00%.

Beyond the cited lines, the fixes were applied at the class level (every CLI TelemetryConfig build site sets the marker; both management endpoints gated; the single canonical audience parser) and verified by an independent multi-dimension review pass before pushing. The three inline threads are resolved.

Follow-up hardening pushed in feed762 (re-requested review).

After R10 I ran a deeper independent adversarial pass (repo-owner persona + completeness critic, double diverse-skeptic verification). It caught that chaffra-management was the one output boundary still reading the raw collector.snapshot() and never projecting — so under the new user-only default it disclosed operator data beyond the backend metadata R10-F2 gated:

• get_modules exposed per-module duration_ms (the operator chaffra.module.call_duration_ms) and an error-derived status sourced from operator_summary.module_error_counts;
• get_metrics surfaced operator data-point names.

Same class as R10-F2, and it also undercut the PR's own "forgetting to project is a compile error" thesis (management read the raw snapshot fields, bypassing ProjectedSnapshot).

Fix: route every snapshot-reading handler (get_metrics, get_modules, get_findings/{summary,churn}, get_health) through the existing project_for_audience guard — closing the leak with the PR's own structural mechanism rather than a hand-rolled per-field filter. Under user-only: operator data points scrubbed, per-module duration_ms zeroed, operator error status withheld. User-facing metrics (finding counts, churn, health_score) are KNOWN_USER and survive. Backend metadata keeps its separate operator_enabled() gate. New tests assert scrub-under-user-only / present-under-operator for both data points and module timing+status; management.md, telemetry.md, and chaffra management --help were reconciled.

One honest note documented rather than silently changed: under operator-only the user-scoped /modules and /health views are now empty (projection drops user data when the user scope is off — the fail-safe under-disclosure direction, not a leak). Sourcing those from the operator summary under operator-only is deferred to Stage 15a.3 alongside the co-located live-collector/history integration, and is called out in the docs.

Gates at feed762 (each by its own exit code): cargo fmt -- --check, cargo clippy -- -D warnings, cargo test --workspace, cargo check --workspace --tests all exit 0. Coverage: overall 94.39%, aggregate_changed 100% (2383/2383), per_file 100%, trust_boundary 100% (api.rs 31/31 changed lines). The verify pass converged with no owner-blocking findings remaining.

Findings

R11-F1 — HIGH — chaffra management still bypasses the shared file-aware telemetry resolver

Command::Management constructs the collector directly from the raw CLI-derived tel_config:

Command::Management { port } => {
    let collector = chaffra_telemetry::TelemetryCollector::new(tel_config);

The resolver-backed telemetry paths use resolve_subcommand_telemetry, which calls load_config(config_path, project_dir)? and then merge_telemetry_config(...) to apply [modules.telemetry] audience/backend precedence and fail closed on malformed config. Management does not call that path.

Impact: chaffra management --config <file> and implicit .chaffra.toml telemetry config are ignored for management. A project with [modules.telemetry] audience = "operator-only" or backend = "stderr" still starts management with the CLI/default config unless CLI telemetry flags are passed; malformed [modules.telemetry] values also do not stop management startup. That leaves a parallel config path exactly where Stage 15a.1 requires one shared CLI/file/default/validation path for telemetry audience privacy.

Fix direction: resolve management telemetry through the same helper/flow as diagnostics and live runs before constructing TelemetryCollector, then add management dispatch tests for file audience, file backend, CLI override precedence, and invalid [modules.telemetry] fail-closed behavior. This finding is summary-only because the offending collector construction is unchanged context outside the current PR diff hunk.

R11-F2 — LOW — Management docs omit off semantics for /modules and /health

docs/api/management.md now documents user-only, on, and operator-only behavior for /modules, and user-only/on/operator-only for /health, but it does not explicitly say what off returns for these snapshot-derived endpoints. Code projects both handlers before reading user summaries/data points, so off also matters and should be documented alongside the other three modes.

Fix direction: add explicit off behavior for /modules and /health so the endpoint docs cover all four audience modes.

Path to Approval (Action Plan)

1. Route chaffra management through the shared file-aware telemetry config resolver before constructing the management collector.
2. Add management dispatch coverage for file audience, file backend, CLI override precedence, and invalid file config fail-closed behavior.
3. Add explicit off behavior to the /modules and /health management API docs.
4. Rerun required CI and coverage after the changes.

@laplaque R11 addressed in 8ec34c1 (re-requested review).

R11-F1 (HIGH) — management bypassed the shared resolver. You're right, and it was the config-source sibling of the projection fix: Command::Management built its collector from the raw CLI-derived tel_config, so a project's [modules.telemetry] audience/backend was ignored and a malformed [modules.telemetry] didn't stop startup. Management now resolves through the same resolve_subcommand_telemetry → load_config + merge_telemetry_config path as live runs and the diagnostics, via a build_management_collector / build_management_collector_in pair (the same wrapper/_in shape the diagnostics use, so the resolution is unit-testable without binding a port). A checked-in audience/backend now governs the management collector, an explicit CLI flag still wins, and malformed config fails closed before the server binds. New tests: test_management_collector_honours_file_audience, _honours_file_backend, _explicit_cli_beats_file, _invalid_file_fails_closed, _wrapper_resolves_cwd.

R11-F2 (LOW) — off undocumented for /modules and /health. Both inline threads resolved: documented off for both (both are user-summary-sourced, so off — like operator-only — yields an empty module list / null health). All four modes are now covered.

Findings

R12-F1 — MEDIUM — ProjectedSnapshot can still be constructed around a raw snapshot inside chaffra-telemetry

ProjectedSnapshot is documented as the type-level guard that makes project_for_audience the only constructor before backend flush/inspect. However the tuple field is pub(crate), so any module in chaffra-telemetry can still construct ProjectedSnapshot(raw_snapshot) directly without projection. The risky output boundaries live in that same crate, including TelemetryModule backend flushing, so this is not just an external API concern: a future same-crate backend/module path can satisfy the backend trait with an unprojected raw snapshot and bypass the Stage 15a.1 structural guard.

Fix direction: make the tuple field private (pub struct ProjectedSnapshot(TelemetrySnapshot);) and keep the existing pub(crate) fn inner(&self) -> &TelemetrySnapshot for backend serialization. That preserves same-crate read access without exposing the constructor.

Path to Approval (Action Plan)

1. Make ProjectedSnapshot's tuple field private so the only constructor is TelemetrySnapshot::project_for_audience.
2. Keep backend serialization access through the existing inner()/Deref read-only APIs.
3. Rerun CI/coverage after the change and refresh the PR evidence if the head changes.

@laplaque R12-F1 addressed in d804bf3 (re-requested review).

Made ProjectedSnapshot's tuple field private (pub struct ProjectedSnapshot(TelemetrySnapshot);). project_for_audience lives in the same module as the type, so it remains the sole constructor; in-crate serialization reads via the pub(crate) inner() accessor and external callers via the public Deref. The pub(crate) field previously left ProjectedSnapshot(raw_snapshot) reachable from within chaffra-telemetry — the same crate that owns the backend/module output boundaries — so an unprojected snapshot could have satisfied TelemetryBackend::flush/inspect; that same-crate bypass of the structural guard is now closed. git grep 'ProjectedSnapshot(' confirms the only construction site is project_for_audience. Inline thread resolved.

Gates at d804bf3 (each by its own exit code): cargo fmt -- --check, cargo clippy -- -D warnings, cargo test --workspace, cargo check --workspace --tests all exit 0. Coverage unchanged: overall 94.40%, aggregate_changed 100% (2449/2449), per_file 100%, trust_boundary 100%.

@laplaque Pushed f2b0be8 (re-requested review). This round I ran the mandated independent adversarial pass proactively (4 lenses — output-boundaries, config-construction, constructor/visibility, coverage/doc — each double-skeptic verified + a completeness critic) to find the next structural sibling before you did, then a convergence pass to confirm closure.

R13-F1 (HIGH) — /config leaked operator-shaped sampling config under user-only. The next sibling of the R10-F2 backends gate: get_config gated only backends, while the sibling sampling_rate / sampling_strategy fields of the same ConfigResponse were serialized unconditionally — disclosing the operator-telemetry emission policy under the default user-only (via the API and the dashboard). Sampling is operator-shaped config metadata by the project's own classification (the sampling-status rule reports "operator telemetry sampling configuration") and lives in TelemetryConfig, not the snapshot, so project_for_audience doesn't scrub it. Fixed: gated both fields on operator_enabled() (now Option, null = withheld under user-only/off, populated under operator); the audience mode is still always reported; dashboard JS renders the withheld case and no longer mis-fires its <1.0 insight on null; docs updated; tests test_config_sampling_withheld_under_user_only / _disclosed_under_operator added.

The convergence pass confirmed the gate is complete (no remaining sampling-disclosure site) and found no further operator-data-under-user-only sibling anywhere on the telemetry surface (all 7 management handlers project; backends + sampling gated on both endpoints; management config goes through the shared fail-closed resolver; ProjectedSnapshot constructor is private).

Gates at f2b0be8 (each by its own exit code): cargo fmt -- --check, cargo clippy -- -D warnings, cargo test --workspace, cargo check --workspace --tests all exit 0. Coverage: overall 94.41%, aggregate_changed 100% (2492/2492), per_file 100%, trust_boundary 100% (api.rs 39/39 changed lines, both sides of the new gate).

• Checked at: 2026-06-29T06:03:26Z
• Review mode: complete R13 rereview from scratch. Previous reviews were treated as historic record only.
• Deep/adversarial pass: re-read the Stage 15a.1 assignment, coordinator constraints, CONTRIBUTING.md, the full changed-file list, current PR diff, current coverage artifact, CI status, R13 delta from 8ec34c1 to 48e8ae4, and searched for duplicated functionality / parallel config or projection paths.

Promotion merge

Not a promotion merge. This is feature branch feat/phase-15a-1-audience-privacy into main for Stage 15a.1. The repository's legacy branch-protection REST endpoint returns 404 Branch not protected; the review therefore treats the PR checks and the project assignment/CONTRIBUTING gates as the merge-quality authorities.

Gate-defining document

• Authoritative assignment: laplaque/chaffra-prompts/01_initialization/phase-15a-telemetry-live-state.md, Stage 15a.1.
• Coordinator constraints: laplaque/chaffra-prompts/01_initialization/coordinator.md.
• Repository instructions: root workspace bootstrap plus repository CONTRIBUTING.md; no nested AGENTS.md was present under laplaque/chaffra.
• Relevant gates applied: default telemetry must be user-only; operator telemetry requires explicit --telemetry on|operator-only or [modules.telemetry] audience; projection must apply before existing output/backend boundaries; no alternate optional config-loading path; invalid config values fail closed; docs/help updated with behavior changes; CI, coverage, fmt, clippy, and tests must pass.
• AI attribution note: the author is iamclaude697, which is covered by the assignment's explicit attribution exemption. I did not treat that identity as a review defect.

Re-review finding ledger

Prior item	Status at 48e8ae4	Evidence
R10-F1 live CLI ignored file backend	Resolved	merge_telemetry_config applies file backend only when cli_backend_override is false, carrying endpoint/path with the parsed backend. Tests cover precedence.
R10-F2 management backend metadata leak	Resolved	/api/v1/metrics and /api/v1/config disclose backend metadata only when audience.operator_enabled().
R10-F3 bare user/operator audience aliases	Resolved	TelemetryAudience::from_str_loose accepts only on, off, user-only/user_only, and operator-only/operator_only; tests reject user, operator, bool, and integer-like aliases.
R10-F4 dependency evidence for tempfile	Resolved	PR body documents tempfile = "3" as an existing workspace dev-dependency, MIT OR Apache-2.0, test-only.
R10-F5 stale verification evidence	Resolved	PR body and CI artifact now reference head 48e8ae4c671893b9121f2c3a9626d5597a97b3eb.
R11-F1 management bypassed shared config resolver	Resolved	Command::Management builds through build_management_collector -> resolve_subcommand_telemetry -> load_config + merge_telemetry_config; tests cover file audience/backend, CLI override, malformed file fail-closed, and wrapper behavior.
R11-F2 docs omitted off for management user-sourced views	Resolved	docs/api/management.md documents off behavior for /modules and /health.
R12-F1 ProjectedSnapshot same-crate constructor bypass	Resolved	ProjectedSnapshot is now pub struct ProjectedSnapshot(TelemetrySnapshot);; git grep finds constructor use only at the private type definition and inside TelemetrySnapshot::project_for_audience. No Deserialize or DerefMut path exists for the wrapper.
R13 self-found sampling config disclosure	Resolved	ConfigResponse.sampling_rate and sampling_strategy are Option; /api/v1/config sets them only under operator_enabled(), dashboard JS handles null, and server tests assert withheld under user-only and present under operator audience.

Quality gates audit

• Scope compliance: Pass. The PR implements Stage 15a.1 audience privacy/configuration changes and leaves live state/history as deferred/not implemented.
• Default privacy: Pass. TelemetryAudience::default() is UserOnly, and default TelemetryConfig inherits it.
• Explicit operator opt-in: Pass. CLI/file parsing resolves through typed audience parsing and shared precedence; MCP has no caller-supplied audience widening parameter.
• Fail-closed config: Pass. Invalid audience/backend/sampling values return typed errors, including malformed implicit .chaffra.toml; sampling alternate spellings are both validated when present.
• Projection before existing output/backend boundaries: Pass. CLI backend flushes, telemetry diagnostics, telemetry module analysis, MCP snapshot, backend traits, and management snapshot-reading handlers route through project_for_audience / ProjectedSnapshot.
• Duplicated functionality / parallel paths: Pass. I specifically checked for management and diagnostic bypasses. Management now uses the same resolve_subcommand_telemetry path as live runs/diagnostics; ProjectedSnapshot construction is no longer available outside collector.rs; management config metadata has explicit non-snapshot gates for backend and sampling metadata.
• Documentation/help: Pass. Telemetry and management docs describe default user-only, operator-only opt-ins, management endpoint redaction, off behavior, nullable /config sampling fields, and deferred 15a.3 history/live integration.
• Dependency gate: Pass based on PR evidence. New direct dependency use is test-only tempfile for chaffra-mcp, already present elsewhere in the workspace and dual MIT OR Apache-2.0.
• Attribution/policy sweep: Pass. AI attribution references are either repository-wide historical instructions/comments or covered by the iamclaude697 exemption.
