+//! Desktop-safe projection of read-only Podman reclaim evidence.
+//!
+//! The headless `podman_reclaim` module intentionally gathers more local detail than the
+//! desktop needs. This module converts that report into a bounded, privacy-safe contract
+//! that contains measurements and stable issue codes, but never machine names, paths,
+//! image identifiers, tags, or shell command text.

+- Add a read-only Podman evidence panel to Cleanup that separately displays configured VM capacity, raw-image logical size, host allocation, guest filesystem observations, Podman store observations, image/stopped-container/volume logical candidates, evidence completeness, stable issue codes, and a redacted candidate-set fingerprint.
+- Add a privacy-safe Tauri contract that removes machine names, local paths, graph-root locations, image identifiers, tags, command output, and dynamic error details before evidence reaches the desktop frontend.

 ### Changed
 
 - Align the frontend toolchain on Vite 8.2 and `@sveltejs/vite-plugin-svelte` 7.2 so the declared peer dependency graph is installable and reproducible.
 - Declare the supported Node.js runtime floor as Node.js 20.19 or Node.js 22.12 and later, matching Vite 8 requirements.
 - Pin the primary test workflow to Node.js 20.19.0 so the minimum supported runtime is continuously verified.
 - Document the iCloud batch operation's local-only versus path-free shareable evidence boundary and map its fail-closed controls to NIST SP 800-53 Release 5.2.0, ISO/IEC 27040:2024, and primary secure-design literature with APA 7th references and deterministic documentation contract tests.
+- Keep Podman image, stopped-container, and volume review boundaries independent and advisory; no candidate class grants authority to another class.

 - Removed obsolete one-shot repair workflows and patch scripts so repository automation no longer retains dormant write-capable recovery paths.
+- Keep the Podman desktop surface observation-only: it exposes no prune, remove, machine stop/start, VM deletion, TRIM, raw-image mutation, or shell-string construction path, and it never labels Podman logical candidates as verified host physical reclaimability.

+# ADR: Privacy-safe Podman desktop evidence
+
+- **Status:** Proposed
+- **Date:** 2026-08-05
+- **Decision owners:** DiskSage maintainers
+- **Related issue:** #107
+- **Related headless contract:** #105 and `src-tauri/src/podman_reclaim.rs`
+
+## Context
+
+DiskSage already has a Rust-first, read-only Podman evidence probe that distinguishes VM configuration, raw-image logical size, host allocation, guest filesystem usage, Podman graph-root observations, and Podman-reported logical cleanup candidates. The desktop Cleanup experience previously had no supported way to inspect that evidence.
+
+The UI must not turn evidence into authority. Podman documents that image reclaimable values can overstate what a prune would actually free when layers are shared. DiskSage therefore treats all `podman system df` candidate values as logical review evidence rather than verified host physical reclaimability.
+
+The headless report also contains local-only details such as machine names, configuration paths, raw-image paths, graph-root paths, and dynamic command errors. Those details are useful for local diagnosis but are unnecessary for the desktop summary and unsafe for telemetry or shareable evidence.
+
+## Decision
+
+### 1. Add a separate privacy projection
+
+`src-tauri/src/podman_desktop.rs` converts `PodmanReclaimPlan` into `PodmanDesktopEvidence`.
+
+The projection includes only:
+
+- configured machine disk bytes;
+- raw-image logical bytes;
+- host allocated bytes;
+- guest total, used, and available bytes;
+- Podman graph-root allocated and used bytes;
+- image, stopped-container, and volume logical candidate bytes;
+- unused-image and stopped-container counts;
+- the SHA-256 commitment to the exact unused-image candidate set;
+- evidence completeness, elapsed time, stable reason codes, and stable issue codes;
+- separate image, stopped-container, and volume review boundaries;
+- `physically_reclaimable_bytes`, which remains unknown until a before-and-after host observation proves it.
+
+The projection excludes:
+
+- machine names and states;
+- configuration, raw-image, and graph-root paths;
+- image identifiers and tags;
+- account-local context;
+- command output and dynamic error details;
+- any mutation command or approval record.
+
+Issue strings are reduced to the stable code before the first colon. Invalid candidate fingerprints fail closed: the fingerprint is removed, the evidence is marked incomplete, and a stable issue code is added.
+
+### 2. Keep the Tauri command read-only and argv-based
+
+`inspect_podman_reclaim` invokes the existing Rust probe using an executable plus an argument vector. It does not construct a shell string. Tauri documents commands as typed Rust functions registered once in `generate_handler!`; the desktop command follows that model and returns a serializable response.
+
+The desktop surface exposes no prune, remove, machine start/stop, VM deletion, TRIM, raw-image mutation, or generic command execution path.
+
+### 3. Keep review domains independent
+
+Images, stopped containers, and local volumes have separate review booleans and separate UI sections. A review signal for one domain never authorizes another domain. This preserves future compatibility with distinct approval records and least-privilege workflows.
+
+### 4. Keep visual semantics explicit and accessible
+
+The panel uses semantic headings, definition lists, buttons, `role="status"` for progress and results, and `role="alert"` for errors. WCAG 2.2 requires status messages to be programmatically determinable without moving focus; the component uses live status regions for that purpose.
+
+The UI never uses color as the only carrier of completeness. Text labels always state “증거 완전” or “부분 증거.”
+
+### 5. Preserve standalone and MSA compatibility
+
+The desktop response is a versioned JSON contract with no dependency on Naruon or another CWL service. DiskSage runs independently. A future Naruon or fleet-management adapter may consume the same privacy-safe schema without receiving local paths or identifiers.
+
+## Consequences
+
+### Positive
+
+- Buyers can inspect a concrete Podman storage gap from the main Cleanup workflow.
+- Logical size, host allocation, guest use, and verified physical reclaimability cannot be silently conflated.
+- Local identifiers stay outside the frontend contract, telemetry, and shareable evidence boundary.
+- The architecture can later add separate governed image, container, and volume approval records without changing the read-only evidence contract.
+- Headless API validation and view-state tests remain deterministic and are included in the 100% frontend statement, branch, function, and line coverage gate.
+
+### Negative
+
+- The UI intentionally cannot perform cleanup. Operators must use a separate reviewed workflow until a mutation design includes exact candidate binding, independent approval, rollback evidence, and before-and-after host verification.
+- Some evidence remains unavailable when Podman is absent, the machine is stopped, or the API is unhealthy. Unknown values remain `null`; the UI never converts missing evidence to zero.
+
+## Verification matrix
+
+| Invariant | Deterministic evidence |
+|---|---|
+| No machine names or paths in desktop JSON | Rust serialization test searches for private fixture values |
+| Image/container/volume review separation | Rust projection test and TypeScript view-model test |
+| Invalid fingerprint fails closed | Rust and TypeScript malformed-fingerprint tests |
+| Missing observations stay unknown | Rust and TypeScript null-preservation tests |
+| Exact Tauri command contract | Mocked TypeScript invoke test |
+| Schema/type/range drift rejected | TypeScript parser tests |
+| Progress and errors announced | Svelte markup uses `role="status"` and `role="alert"` |
+| No mutation surface | Registered command list exposes inspection only |
+| Frontend logic coverage | `vitest.config.ts` includes `podmanEvidence.ts` at 100% thresholds |
+
+## Release acceptance
+
+This slice is release-eligible only after the exact integrated head passes:
+
+1. Rust formatting and tests, including `podman_desktop` tests;
+2. frontend unit tests and 100% coverage thresholds;
+3. Svelte type checking and production build;
+4. security and SAST workflows;
+5. current-head review with no unresolved actionable finding;
+6. independent non-author approval;
+7. packaging, provenance, and release-acceptance workflows.

 - Add a read-only Podman evidence panel to Cleanup that separately displays configured VM capacity, raw-image logical size, host allocation, guest filesystem observations, Podman store observations, image/stopped-container/volume logical candidates, evidence completeness, stable issue codes, and a redacted candidate-set fingerprint.
 - Add a privacy-safe Tauri contract that removes machine names, local paths, graph-root locations, image identifiers, tags, command output, and dynamic error details before evidence reaches the desktop frontend.

 The panel uses semantic headings, definition lists, buttons, `role="status"` for progress and results, and `role="alert"` for errors. WCAG 2.2 requires status messages to be programmatically determinable without moving focus; the component uses live status regions for that purpose.
 
 The UI never uses color as the only carrier of completeness. Text labels always state “증거 완전” or “부분 증거.”
 
+The UI never renders `String(reason)` or another untrusted exception representation. `podmanEvidenceErrorMessage` discards every transport, operating-system, and JavaScript failure detail and returns only `podman-evidence-unavailable`. Detailed diagnosis remains confined to trusted local logs and does not cross into the desktop evidence, telemetry, or shareable-evidence boundary.

 ### Negative
 
 - The UI intentionally cannot perform cleanup. Operators must use a separate reviewed workflow until a mutation design includes exact candidate binding, independent approval, rollback evidence, and before-and-after host verification.
 - Some evidence remains unavailable when Podman is absent, the machine is stopped, or the API is unhealthy. Unknown values remain `null`; the UI never converts missing evidence to zero.
+- Visible failures intentionally use a stable generic code; sensitive operational detail must be inspected through trusted local diagnostics rather than the shareable desktop surface.

+# Exact-head coverage evidence
+
+DiskSage treats code coverage as durable CI evidence rather than a locally asserted percentage. The `Test` workflow measures Rust production coverage on the exact pull-request head and emits a machine-readable `coverage-evidence` artifact only when all required metrics are exactly 100%.
+
+## Why the workflow checks out the exact head
+
+GitHub pull-request workflows may otherwise execute against a synthetic merge commit. That is useful for integration testing, but it is not sufficient for a review gate that claims a result about one immutable pull-request head. The coverage job therefore checks out `${{ github.event.pull_request.head.sha || github.sha }}` explicitly and copies the same value into `HEAD_SHA`.
+
+The evidence builder rejects a missing or malformed SHA. Both `head_sha` and `commit_sha` in `coverage-evidence.json` must equal that exact 40-character commit identifier. The repository identity is taken from `GITHUB_REPOSITORY`, not from user-controlled test output.
+
+## What is measured
+
+The workflow uses `cargo llvm-cov` with LLVM source-based instrumentation. Branch coverage is requested explicitly with `--branch`; because cargo-llvm-cov documents branch coverage as unstable, the workflow uses an immutable dated Rust nightly with `llvm-tools-preview` instead of silently falling back to a toolchain that cannot measure the required metric.
+
+The JSON summary is the only source for the emitted percentages. The evidence builder reads LLVM's aggregate totals and requires all of the following to be present, finite, non-empty, fully covered, and exactly 100%:
+
+- statement coverage: LLVM region coverage, used as the statement-equivalent source-based metric;
+- branch coverage: LLVM branch totals;
+- function coverage: LLVM function totals; and
+- line coverage: LLVM line totals.
+
+The workflow never manufactures a percentage from a successful test exit status. Missing totals, zero denominators, partial coverage, malformed JSON, or identity drift stop the job before the artifact can be uploaded.
+
+## Evidence contract
+
+A valid `coverage-evidence.json` has schema version `1` and records the immutable head, repository, CI trust tier, server, workflow name, coverage command, four exact percentages, and `passed: true`. The organization review workflow independently downloads this artifact from the successful `Test` run for the same head and revalidates the contract.
+
+The artifact is uploaded with `if-no-files-found: error`. GitHub Actions artifacts persist workflow outputs such as test and coverage results after the producing job completes, which lets the organization-level reviewer consume evidence without granting the coverage job repository-write permission.
+
+## Fail-closed operating rule
+
+A missing `coverage-evidence` artifact is not equivalent to passing coverage. A queued, cancelled, failed, stale-head, malformed, or less-than-100% measurement is also not passing. Engineers must add realistic tests or remove genuinely unreachable production code; they must not lower thresholds, hard-code percentages, exclude reachable production arithmetic merely to satisfy the gate, or reuse an artifact from an older head.

 ### Changed
 
+- Require the `Test` workflow to produce exact-head, branch-aware, fail-closed Rust coverage evidence from real `cargo llvm-cov` measurements before organization-level review can treat 100% statement-equivalent region, branch, function, and line coverage as passing.
 - Require a fresh, exact, human-attributed approval and rationale for cloud copy-only and existing-copy adoption actions, with a 15-minute authorization lifetime bound to the candidate, destination, provider, account scope, and review fingerprint.
 - Return the candidate-specific cloud copy approval action, exact confirmation phrase, and maximum approval age from the Rust plan contract; the frontend only displays and submits that backend-authored phrase and fails closed when it is missing or does not match the candidate action.
 - Align the frontend toolchain on Vite 8.2 and `@sveltejs/vite-plugin-svelte` 7.2 so the declared peer dependency graph is installable and reproducible.

Branch coverage is requested explicitly with `--branch`; because cargo-llvm-cov documents branch coverage as unstable, the workflow uses an immutable dated Rust nightly with `llvm-tools-preview` instead of silently falling back to a toolchain that cannot measure the required metric.
 
+The workflow passes `--no-cfg-coverage` and `--no-cfg-coverage-nightly`, so cargo-llvm-cov does not define its normal `cfg(coverage)` or `cfg(coverage_nightly)` build configurations. Production code guarded by `#[cfg(not(coverage))]` therefore remains in the measured graph rather than disappearing merely because coverage is being collected. This keeps the gate aligned with the production-behavior requirement; it also means unreachable GUI or command boundaries must be made realistically testable rather than hidden from measurement.

+## Evidence and failure diagnostics
 
 A valid `coverage-evidence.json` has schema version `1` and records the immutable head, repository, CI trust tier, server, workflow name, coverage command, four exact percentages, and `passed: true`. The organization review workflow independently downloads this artifact from the successful `Test` run for the same head and revalidates the contract.
 
-The artifact is uploaded with `if-no-files-found: error`. GitHub Actions artifacts persist workflow outputs such as test and coverage results after the producing job completes, which lets the organization-level reviewer consume evidence without granting the coverage job repository-write permission.
+The success artifact is uploaded with `if-no-files-found: error`. GitHub Actions artifacts persist workflow outputs such as test and coverage results after the producing job completes, which lets the organization-level reviewer consume evidence without granting the coverage job repository-write permission.
+
+When any metric is below 100%, the job still writes the bounded `coverage-diagnostic.json` containing only the exact head/repository identity and aggregate region, branch, function, and line totals. The same bounded diagnostic is emitted to the job log and `GITHUB_STEP_SUMMARY` before validation throws, then uploaded with `if: always()`. This makes the first failing coverage boundary directly observable without exposing source contents, local paths, secrets, test fixtures, or command output, while the success-only `coverage-evidence.json` remains fail closed.
 
 ## Fail-closed operating rule
 
-A missing `coverage-evidence` artifact is not equivalent to passing coverage. A queued, cancelled, failed, stale-head, malformed, or less-than-100% measurement is also not passing. Engineers must add realistic tests or remove genuinely unreachable production code; they must not lower thresholds, hard-code percentages, exclude reachable production arithmetic merely to satisfy the gate, or reuse an artifact from an older head.

 - Require the `Test` workflow to produce exact-head, branch-aware, fail-closed Rust coverage evidence from real `cargo llvm-cov` measurements before organization-level review can treat 100% statement-equivalent region, branch, function, and line coverage as passing.
+- Surface the same bounded exact-head Rust coverage totals in the failing job log and GitHub step summary before enforcing the 100% gate, while retaining the success-only coverage evidence artifact and privacy-safe diagnostic artifact boundary.
 - Require a fresh, exact, human-attributed approval and rationale for cloud copy-only and existing-copy adoption actions, with a 15-minute authorization lifetime bound to the candidate, destination, provider, account scope, and review fingerprint.
 - Return the candidate-specific cloud copy approval action, exact confirmation phrase, and maximum approval age from the Rust plan contract; the frontend only displays and submits that backend-authored phrase and fails closed when it is missing or does not match the candidate action.
 - Align the frontend toolchain on Vite 8.2 and `@sveltejs/vite-plugin-svelte` 7.2 so the declared peer dependency graph is installable and reproducible.
