Executive summary + +Fase 3 of Charter-01 is scoped as "implement the GTK4 preferences panel +(currently a `println!("not yet implemented")` stub)". That stub is only the +placeholder `lnxdrive-gnome/src/main.rs`; the **real panel already exists and is +~95% built** under `lnxdrive-gnome/preferences/` — an `adw::Application` with a +typed zbus client, an onboarding wizard, and four pages (Account, Sync, +Conflicts, Advanced). It **compiles** (`cargo check` clean, 12 warnings) and, +unlike the FUSE crate audited in Fase 2, it **does not have a fatal runtime trap** +(async is correctly `async-io` + glib `spawn_local`, no stray `block_on`/ +`tokio::spawn`; GSettings schema id/keys, app-id, and build wiring are +consistent). + +The audit was run because "compiles" is not "works" — the panel had never been +exercised against a real daemon, and the zbus proxy contract is validated at +**runtime**, not compile time. Three Explore agents (D-Bus contract / UI logic / +async+build) produced findings that the calibrator reconciled and verified +against source, rejecting four agent over-classifications. + +**The one serious finding is a cross-component governance drift (H1):** Fase 1 +(RISK-002) removed `Auth.CompleteAuthWithTokens` from the daemon and replaced it +with `Auth.CompleteAuthViaGOA` to keep OAuth tokens off the D-Bus surface, but +the **panel was never updated** — it still declares/calls `complete_auth_with_tokens` +(now nonexistent), and that GOA code is behind `#[cfg(feature = "goa")]` while +`Cargo.toml` defines **no `goa` feature**, so GOA SSO is compiled out entirely. +This is the **third occurrence (N=3)** of the "declared but not wired" pattern +already reported upstream to StrayMark (#205) — and the first one that is a +*regression* of a shipped Fase-1 mitigation rather than an original gap. + +Mitigating fact: the **manual browser auth path works** (`start_auth()` + +`AuthStateChanged` signal, both present on the daemon — `auth_page.rs:238-295`), +so the panel can still authenticate; only the GOA "use your existing Microsoft +account" path (FR-019–023) is broken. Hence H1 is **High, not Critical**. + +**Overall verdict: FUNCTIONAL_WITH_DRIFT.** The panel runs and mostly works; the +material work is fixing the RISK-002 drift, three medium robustness items, lint +cleanup, and the absent "System" group. + +## 2. Scope + +Audited: every Rust source under `lnxdrive-gnome/preferences/src/`, the zbus +client contract against the daemon's interfaces in +`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs`, plus `Cargo.toml`, +`meson.build`, the GSettings schema, and the desktop/metainfo files. Not run: +live execution against a mounted daemon (no authenticated account available in +this environment) — deferred to manual verification. + +## 3. Findings (calibrated) + +### H1 — RISK-002 drift: GOA auth broken & compiled out — **HIGH** + +- **Client** declares and calls `complete_auth_with_tokens(access_token, + refresh_token, expires_at_unix)` — `dbus_client.rs:88,235-243` and + `onboarding/auth_page.rs:362`. +- **Daemon** removed that method in Fase 1; only `complete_auth(code, state)` + (`service.rs:873`) and `complete_auth_via_goa(goa_account_path)` + (`service.rs:917`) exist. `service.rs:902` states it "replaces the historical + `CompleteAuthWithTokens`"; the tests at `service.rs:2004` confirm it was + deleted. +- The GOA UI is gated on `#[cfg(feature = "goa")]` (`auth_page.rs:20,35,143,338`) + but `preferences/Cargo.toml` defines **no `[features]`** → the gate is always + false → GOA SSO is compiled out (also the source of the `unexpected cfg value + 'goa'` warnings). +- **Impact:** GOA SSO (FR-019–023) is non-functional and, if re-enabled as-is, + would call a method the daemon no longer exposes (`UnknownMethod` at runtime). + Manual browser auth is unaffected. +- **Remediation:** (a) add `[features] goa = []` (decide default on/off) to + `Cargo.toml`; (b) add a `complete_auth_via_goa(goa_account_path)` proxy method + to `dbus_client.rs` and drop/deprecate `complete_auth_with_tokens`; + (c) rewrite `auth_page.rs::on_goa_sign_in_clicked` to pass the GOA account + object path to `complete_auth_via_goa` instead of fetching tokens client-side. + +### H2 — Daemon state not consumed (no live status) — **MEDIUM** + +- The client proxies omit several daemon-exposed properties/signals: `Sync` + `sync_status`/`last_sync_time`/`pending_changes` + `sync_started`/ + `sync_completed`/`sync_progress` (`service.rs:652-705`); `Status` + `connection_status`/`dbus_health` + `quota_changed`/`connection_changed` + (`service.rs:762-790`); `Settings.config_changed` (`service.rs:1066`). +- **Impact:** the panel shows no live sync/connection status and does not refresh + on external changes. Functional gap, not a crash. +- **Remediation:** add the missing properties/signals to the proxies and wire a + minimal set (sync status + quota refresh) into the relevant pages. + +### H3 — Silent error handling — **MEDIUM** + +- D-Bus call failures go to `eprintln!`/stderr, not the UI (e.g. + `sync_page.rs:200`, `account_page.rs`), so a dead daemon leaves the panel + showing default values as if loaded. +- JSON parsing uses `unwrap_or_default()` (`folder_tree.rs:416`), so a malformed + `GetRemoteFolderTree` response renders an **empty tree indistinguishable from + "no folders"**. +- **Impact:** silent degradation; user operates on stale/empty UI believing it + loaded. +- **Remediation:** surface load/save failures via an `adw::Toast`/banner; + distinguish parse-error from empty in `folder_tree`. + +### H4 — `folder_tree` load race — **MEDIUM** + +- `FolderTree::new` fires `load_remote_tree()` and `load_selected_folders()` as + two independent `spawn_local` tasks (`folder_tree.rs:205-206`); `apply_selections` + can run before the tree is populated, dropping the selection highlight. A + related issue: `apply_selections` only walks root-level nodes, so lazily-loaded + children are not marked. +- **Impact:** selective-sync selections may not display correctly. +- **Remediation:** chain selections after the tree populates (await both, or + apply selections in the populate continuation); apply recursively as nodes + expand. + +### H5 — Compiler warnings — **LOW** + +- 12 warnings: unused `gtk4::prelude` imports (`sync_page.rs:11`, + `onboarding/mod.rs:17`, `app.rs:12`), `unexpected cfg value 'goa'` (resolved by + H1's feature definition), deprecated `ActionRowBuilder::icon_name` + (`confirm_page.rs:90,96`). +- **Remediation:** remove unused imports; migrate the deprecated builder call; + the `cfg` warnings disappear once `goa` is a declared feature. + +### G1 — "System" settings group absent — **GAP** + +- The Charter names four groups (Account, Folders, Network, System). The panel + has Account, Sync (≈Folders), Advanced (≈Network), Conflicts — but **no + "System" group**, and the daemon exposes **no D-Bus API** for its candidate + settings (auto-start, cache, dehydration policy). +- **Remediation (decision required):** auto-start is implementable without new + D-Bus API (manage a systemd user unit / autostart `.desktop`); cache and + dehydration controls need daemon API and are **deferred to v0.2**. Either ship + a "System" page with only the implementable controls, or document the group as + deferred. To be decided during remediation. + +## 4. Rejected (agent over-classifications) + +The calibrator verified and **rejected** these as not-a-bug for this codebase: + +- **`.expect()` cascade in GTK factories** (`folder_tree.rs:227,260-318`) — flagged + CRITICAL by the UI agent, but these are idiomatic gtk4-rs factory closures where + the item type is guaranteed by construction (`TreeListModel`/`ListItem` always + yield the registered type). The async+build agent correctly rated them low. + **Rejected as CRITICAL; at most a stylistic LOW.** +- **`Files` interface missing from client** — the panel is the *preferences* UI; + pin/unpin/file-status is Nautilus' concern, not this binary's. **Not applicable.** +- **`conflict_list.rs:296` `STRATEGY_VALUES[i]` index** — the two arrays are + fixed-size consts of equal length; no runtime risk exists today. **LOW, not + CRITICAL.** +- **async-runtime deadlock (FUSE-style)** — verified absent: zbus uses `async-io` + (not tokio), all D-Bus calls run via `glib spawn_local`, no `block_on`. **No bug.** + +## 5. Remediation plan (→ Fase 3 implementation) + +Ordered, each on the `feat/charter-01-phase-3-*` branch with regression coverage +where testable and a closing AILOG: + +1. **H1 (High):** define the `goa` feature; replace the client/`auth_page` token + path with `complete_auth_via_goa`. Backport a governance note (this is a + Fase-1 RISK-002 regression) and feed the N=3 "declared but not wired" data + point into the upstream-feedback drafts. +2. **H3 (Medium):** toast/banner on D-Bus errors; parse-error vs empty in + `folder_tree`. +3. **H4 (Medium):** fix the `folder_tree` load ordering + recursive selection. +4. **H2 (Medium):** extend proxies and wire live sync/quota status. +5. **G1 (Gap):** decide System-group scope; implement auto-start or document + deferral. +6. **H5 (Low):** clear warnings + deprecation. + +Verification: `cargo clippy -p lnxdrive-preferences -- -D warnings` clean; unit +tests for any non-GTK logic added; manual run against a live daemon recorded in +the closing AILOG (the panel cannot be exercised end-to-end in CI — same +`/dev/fuse`/display constraint class as the T101 mount test).

Define the `goa` feature (default on); add the complete_auth_via_goa proxy and drop complete_auth_with_tokens; rewrite on_goa_sign_in_clicked to hand the GOA account path to the daemon (tokens never cross D-Bus). Fixes a latent type error in goa_sso that had never compiled (the feature was always off). - H4 (Medium) — folder_tree load race: load_remote_tree and load_selected_folders ran as two independent tasks, so selections could apply to an empty tree. Merge into one ordered task (selections first, then populate). - H3 (partial) — folder_tree now surfaces load/parse errors inline instead of failing silently to stderr; a malformed tree is no longer shown as "empty". - H5 — cargo check is now clean: removed unused imports, migrated the deprecated ActionRow::icon_name to add_prefix. Still open (this branch): H3 error toasts in sync/account pages, H2 (consume daemon properties/signals), G1 (System group). cargo check clean; note 145 pre-existing clippy needless_borrow lints across the panel (separate debt).

It ships **three** settings groups wired to the daemon — Account, Folders (Sync), Network (Advanced) — plus Conflicts. The fourth group, **System** (auto-start, cache, dehydration), is **deferred to a v0.2 Charter** because it needs new daemon D-Bus API and is post-alpha (see AIDEC-2026-05-31-001).

Fix `lnxdrive.spdx` (currently describes StrayMark by mistake). Complete the metainfo XML with description, releases section, and screenshot URLs. 6. **Release infrastructure & public assets** — `.github/workflows/release.yml` (tag → bundle → GitHub Release with SHA256SUMS); `SECURITY.md`; `CHANGELOG.md`; 6 UI screenshots in `docs/screenshots/`; version `0.1.0-alpha.1` consistent across every `Cargo.toml`, Flatpak manifest, and metainfo XML; README install section + competitive comparison vs `jstaf/onedriver` and `abraunegg/onedrive`. 7. **Tag, release, announce** — signed tag `v0.1.0-alpha.1`, GitHub Pre-release with Flatpak bundle, posts on r/linux, r/gnome, r/onedrive, and StrangeDaysTech Mastodon.

This is the **third + occurrence (N=3)** of the "declared but not wired" pattern reported upstream to + StrayMark (#205), and the first that is a *regression* of a shipped Fase-1 + mitigation. Fix: define the `goa` feature (default on); add the + `complete_auth_via_goa` proxy and drop `complete_auth_with_tokens`; hand the + GOA account object-path to the daemon (tokens never client-side). This also + surfaced and fixed a latent type error in `goa_sso` that had **never compiled** + (the feature was always off) — concrete evidence the GOA path was dead code. + The manual browser auth path (`start_auth` + `AuthStateChanged`) was unaffected. +- **H2 (Medium) — daemon state not consumed.** Added the missing Sync/Status + properties+signals and `Settings.config_changed` to the proxies, and wired a + real consumer (AccountPage refreshes quota on `QuotaChanged`). +- **H3 (Medium) — silent errors.** `folder_tree`, `sync_page`, and the onboarding + pages now surface load/save failures in the UI (inline error, error group, + toast/banner) instead of stderr; `folder_tree` distinguishes a parse error from + an empty tree. +- **H4 (Medium) — folder_tree load race.** Merged the two independent load tasks + into one ordered task (selections first, then populate) so selections can no + longer apply to an empty tree. +- **H5 (Low) — lint debt.** `cargo check` warnings cleared (unused imports, + deprecated `ActionRow::icon_name` → `add_prefix`); the audit also surfaced 145 + pre-existing `needless_borrow` clippy lints across the panel (the panel had + never passed clippy `-D warnings`), auto-fixed in this pass. +- **G1 (gap) — "System" settings group.** Deferred to a v0.2 Charter + ([[AIDEC-2026-05-31-001]]): cache/dehydration need new daemon D-Bus API and are + post-alpha.

Shell extension and Nautilus integration + operational; the GTK4 preferences panel (`src/main.rs`) is a `println!` + stub. GOA provider just landed in PR #2. +- **lnxdrive-gtk3 / lnxdrive-plasma / lnxdrive-cosmic**: 5–10% — Cargo / + CMake skeletons with `not yet implemented` stubs. +- **lnxdrive-packaging**: Flatpak manifest is partial (no + metainfo/desktop/icon install stages); RPM, DEB, AUR, AppImage are + named in `lnxdrive-packaging/README.md` but do not exist. +- **lnxdrive-testing**: ~80% — Podman + QEMU + nested-GNOME infra works. +- **SpecKit**: `001-core-cli` 254/254 ✅; `002-files-on-demand` 105/106 + (99.1%, 1 task pending). +- **CI**: `lnxdrive-engine/.github/workflows/ci.yml` runs `fmt + clippy + + build` but **does not run `cargo test`** and no release automation + exists. Zero GitHub Releases, zero tags, zero milestones, zero public + issues, zero UI screenshots. +- **`SECURITY.md`**: absent. `lnxdrive.spdx` describes StrayMark, not + LNXDrive (a packaging copy/paste bug to fix during release prep). +- **StrayMark risks**: four P0 entries documented in + `.straymark/02-design/risk-analysis/` with **no remediation AILOGs**: + - `RISK-002` — OAuth tokens travel in cleartext over D-Bus + (CVSS 9.1). Inspecting the session bus with `dbus-monitor` would + expose `Bearer …` strings. Hard blocker for any public release. + - `RISK-003` — write-during-hydration race in the FUSE layer can + corrupt files; `crates/lnxdrive-fuse/src/write_serializer.rs` + exists as a stub. + - `RISK-001` — D-Bus session bus is a single point of failure for + the daemon ↔ UI link. + - `ISSUE-002` — config YAML parser is susceptible to a + billion-laughs DoS. + +## Decisions taken with the human operator (2026-05-29) + +These decisions were taken before any code change. They define the +boundaries of the Charter that this AILOG originates. + +1. **Target = v0.1.0 alpha for early adopters**, not v1.0 mass-market. + Audience is Linux power users and GNOME enthusiasts willing to + report bugs. Estimated 4–6 weeks (5–7 calendar weeks with margin). +2. **GNOME-only in scope.** `lnxdrive-gtk3`, `lnxdrive-plasma` and + `lnxdrive-cosmic` move to `experimental/` with a README that marks + them as post-1.0 placeholders. Not built in CI. Not referenced from + the alpha packaging manifest or README's install matrix. +3. **P0 risks block the release.** No artifact ships until RISK-001, + RISK-002, RISK-003 and ISSUE-002 have remediation AILOGs (and ETHs + for the credential-handling one) plus regression tests. RISK-002 is + the hardest constraint: tokens must move to `secret-service` + (libsecret) via `keyring-rs`; the D-Bus interface must expose only + opaque `SessionHandle` values, never raw tokens. +4. **Public-facing work tracking.** The 27 entries of + `.straymark/02-design/risk-analysis/BACKLOG-simulation-issues.md` + plus the four P0 items become GitHub issues with labels (P0–P3, + `security`, `architecture`, …) and milestones (`v0.1.0-alpha`, + `v0.2.0-beta`, `v1.0.0`), grouped under a `Road to v0.1.0` + GitHub project board. + +## Plan phases (Charter-level outline) + +The Charter that follows this AILOG declares these phases as scope.

The operator audited the state on 2026-05-28 and decided on 2026-05-29 to ship a focused v0.1.0 alpha for Linux/GNOME early adopters rather than continue spreading effort across four UIs.

AILOG with `risk_level: high` + ETH. + - `RISK-003`: implement `lnxdrive-engine/crates/lnxdrive-fuse/src/write_serializer.rs` (currently a stub) with per-inode locking during hydration. + - `RISK-001`: D-Bus health monitor + reconnect in `lnxdrive-daemon`. Full Unix-socket fallback explicitly deferred to v0.2. + - `ISSUE-002`: harden the YAML config parser against billion-laughs (size + alias caps); regression fixture in `lnxdrive-engine/tests/security/`. + - `cargo audit` + `cargo deny` jobs in CI. +3. **Engine polish** — close the one remaining task in `lnxdrive-engine/specs/002-files-on-demand/tasks.md`; remove the ~4 `todo!()/unimplemented!()` sites and ~10 debug `println!` calls; enable `cargo test --workspace` in CI. +4. **GTK4 preferences panel** — implement four basic settings groups (Account, Folders, Network, System) in `lnxdrive-gnome/src/main.rs` (currently a `println!("not yet implemented")` stub) wired to the existing D-Bus daemon API. +5. **Flatpak packaging** — complete `lnxdrive-packaging/flatpak/com.strangedaystech.LNXDrive.yaml` with install stages (icons, `*.desktop`, metainfo XML), correct permissions (`--filesystem=home:rw`, `--talk-name=org.freedesktop.secrets`), and target `org.gnome.Platform 47`. Fix `lnxdrive.spdx` (currently describes StrayMark by mistake). Complete the metainfo XML with description, releases section, and screenshot URLs. +6. **Release infrastructure & public assets** — `.github/workflows/release.yml` (tag → bundle → GitHub Release with SHA256SUMS); `SECURITY.md`; `CHANGELOG.md`; 6 UI screenshots in `docs/screenshots/`; version `0.1.0-alpha.1` consistent across every `Cargo.toml`, Flatpak manifest, and metainfo XML; README install section + competitive comparison vs `jstaf/onedriver` and `abraunegg/onedrive`. +7. **Tag, release, announce** — signed tag `v0.1.0-alpha.1`, GitHub Pre-release with Flatpak bundle, posts on r/linux, r/gnome, r/onedrive, and StrangeDaysTech Mastodon. + +**Out of scope:** + +- GTK4 preferences panel features beyond the four basic groups — deferred to milestone `v0.2.0-beta`. +- KDE Plasma, GTK3 (XFCE/MATE), COSMIC UIs — archived under `experimental/`, deferred to milestone `v1.0.0`. +- RPM, DEB, AUR, AppImage packaging — deferred to milestone `v0.2.0-beta` (alpha ships Flatpak only). +- Flathub submission — deferred to milestone `v0.2.0-beta`. +- i18n / translations — structure in `v0.2.0-beta`, 5+ languages in `v1.0.0`. +- Telemetry / crash reporting — deferred to milestone `v0.2.0-beta`. +- Landing page on strangedays.tech — deferred to milestone `v0.2.0-beta`. +- D-Bus full Unix-socket fallback — alpha ships only the health monitor; full fallback in `v0.2.0-beta`. +- `cargo tarpaulin` coverage reports — best-effort in alpha, formal target in `v0.2.0-beta`. + +## Files to modify + +This Charter spans many files across 7 phases.

The original Charter entry pointed at `write_serializer.rs` based on the risk doc; audit on 2026-05-28 confirmed `write_serializer.rs` was already implemented (serializes DB writes via `tokio::sync::mpsc`) and the actual data-integrity gap was the FUSE write path. (Fase 1) | +| `lnxdrive-engine/crates/lnxdrive-daemon/src/{health.rs (new), main.rs}` + `lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs` | `RISK-001`: D-Bus session bus health monitor + reconnect. New `health.rs` supervises the connection (active `get_id()` probe + timeout; reconnect with backoff re-registering all 9 interfaces; yields on name-taken). `main.rs` wraps `DbusService` in `Arc`, hands the connection to the monitor, and splits `run`/`run_inner` for a single monitor-join exit point. `service.rs` adds a `DaemonState::dbus_health` field + read-only `dbus_health` property on `StatusInterface` (distinct from cloud `connection_status`). Original entry named only `health.rs`; `main.rs` + cross-crate `service.rs` added atomically (drift R7, AILOG-2026-05-28-002). NameLost fast-path and full Unix-socket fallback deferred to v0.2. (Fase 1) | +| `lnxdrive-engine/Cargo.toml` + `crates/lnxdrive-core/src/config.rs` + `crates/{lnxdrive-core,lnxdrive-cli}/Cargo.toml` + `crates/lnxdrive-cli/src/commands/config.rs` + `lnxdrive-engine/tests/security/billion_laughs.yaml` (new) | `ISSUE-002`: YAML hardening + regression fixture. Migrate `serde_yaml 0.9` (deprecated) → `serde_norway` (RUSTSEC-recommended fork with built-in recursion + alias-repetition caps, on by default), and add a 1 MiB input size cap in a new `Config::from_yaml_str`. Original entry named `lnxdrive-config/src/parser.rs` (no such crate exists); the real config parser is `lnxdrive-core/src/config.rs`. Final mitigation shape = in-tree size cap + alias cap delegated to the library (not a hand-written pre-scanner). Dependency decision recorded in AIDEC-2026-05-28-001; details + cross-crate sweep (lnxdrive-cli) in AILOG-2026-05-28-003. (Fase 1) | +| `.github/workflows/engine-ci.yml` (new, repo root) + `lnxdrive-engine/deny.toml` (new) + workspace `Cargo.toml`/`Cargo.lock` | `cargo deny` + supply-chain hardening (Fase 1). **Premise correction:** the engine CI lived at `lnxdrive-engine/.github/workflows/ci.yml`, a subdirectory path GitHub Actions ignores, so it **never ran** (fmt/clippy/build/test/audit never enforced). Relocate to the repo root with `working-directory` + path filter so it runs; add a `cargo-deny` job + `deny.toml` (subsumes the planned separate `cargo audit`).

Production callers ++(`lnxdrive-daemon/src/main.rs`, `lnxdrive-cli/src/commands/sync.rs`) ++correctly load the token from the system keyring before constructing ++the client, so the invariant "tokens come only from the keyring" is ++respected at runtime — but it is not enforced at compile time. A ++malicious refactor (or a careless future change) could re-introduce a ++code path that constructs `GraphClient` from a token obtained over an ++unsafe channel. ++ ++The mitigation for **RISK-002** that landed in `AILOG-2026-05-29-002` ++removed the D-Bus method that accepted tokens. This TDE proposes the ++compile-time complement: replace the `access_token: String` constructor ++argument with a `Box` (or `Arc`) so ++that all GraphClient instances trace their token to a typed source. ++ ++## Context ++ ++During the audit that produced `AILOG-2026-05-29-001` and the ++implementation in `AILOG-2026-05-29-002` we explicitly discussed ++whether to introduce the `TokenSource` trait now or defer it. The ++operator chose **defer**: the production callers already load tokens ++from the keyring, so the additional refactor does not close any new ++attack surface today. Filing this TDE is the bookkeeping of that ++decision. ++ ++The audit found 19 callsites of `GraphClient::{new, with_base_url}`, ++of which 17 are tests using hard-coded fake tokens (`"test-token"`, ++`"old-token"`, `"expired-token"`, …). The remaining 2 are production ++callers in the daemon and CLI. ++ ++## Proposed remediation ++ ++1. Add a `TokenSource` trait in `lnxdrive-graph` (or `lnxdrive-core`): ++ ++ ```rust ++ #[async_trait] ++ pub trait TokenSource: Send + Sync { ++ async fn access_token(&self) -> Result; ++ } ++ ``` ++ ++2. Provide two concrete implementations in `lnxdrive-graph`: ++ - `KeyringTokenSource { username: String }` — loads the access token ++ from the keyring on demand, transparently refreshes via ++ `OAuth2Provider::refresh` or `refresh_via_goa` when expired. ++ - `StaticTokenSource { token: String }` — `#[cfg(test)]` (or ++ gated behind a `unstable-test-utils` feature) for tests. ++ ++3. Change `GraphClient::new(access_token)` → `GraphClient::new(source: Arc)`. ++ Update the 2 production callsites; provide a `GraphClient::with_static_token(token)` ++ helper to keep the 17 test callsites short. ++ ++4. Internally, `GraphClient` calls `source.access_token().await` lazily ++ inside `execute_with_retry` rather than caching the string in a ++ field. This also closes a smaller debt: the current `GraphClient` ++ never refreshes its `access_token` field across the lifetime of an ++ instance. ++ ++## Why it is debt, not a bug ++ ++The runtime invariant "tokens come only from the keyring" holds today. ++A future bug that violates it would need to either ++(a) ship a new D-Bus method that accepts a raw token (the ++`leak-test-dbus-tokens.sh` integration test would fail), or ++(b) introduce a new in-process code path that constructs `GraphClient` ++from an unsafe string (compile would succeed, no test fails). ++ ++This TDE addresses (b) by removing the `String`-accepting constructor ++entirely. It is **defense in depth**, not a primary mitigation. ++ ++## Why not now ++ ++- The current scope of `CHARTER-01-road-to-v0-1-0-alpha-1` is ++ release-blocker work. The refactor touches 19 callsites and exercises ++ the auth flow end-to-end; a regression in that path is harder to ++ debug late in the release cycle than a regression in a D-Bus ++ surface change. ++- All 17 test callsites would need a parallel migration. With the ++ current architecture they pass `"test-token"` as a plain string; ++ after the refactor they would either use a helper or wire a ++ `StaticTokenSource`. The behaviour is identical, but the churn is ++ meaningful for `git blame` clarity. ++- The runtime safety we want for v0.1.0-alpha.1 is already provided by ++ the keyring + D-Bus method removal. The compile-time enforcement is ++ strictly an improvement, not a precondition. ++ ++## Activation triggers for this TDE ++ ++Any one of the following should promote this debt to active work in a ++new Charter: ++ ++- A second mitigation finds that `GraphClient` is being constructed ++ from a non-keyring source somewhere (proves the runtime invariant ++ was already broken). ++- A new cloud provider lands (Google Drive, Dropbox) that introduces ++ its own client class. Sharing a `TokenSource` trait across providers ++ becomes valuable for shared refresh logic. ++- The `lnxdrive-graph` crate is split into smaller crates for ++ v1.0.0 — natural moment to introduce the abstraction. ++ ++## Suggested milestone ++ ++`v0.2.0-beta` of LNXDrive. Coupled with the broader CI hardening Fase ++(which adds `cargo audit` / `cargo deny` / coverage), since they share ++the "defense-in-depth" theme. +diff --git a/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-001-mitigate-risk-003-fuse-write-during-hydration.md b/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-001-mitigate-risk-003-fuse-write-during-hydration.md +new file mode 100644 +index 0000000..982e00e +--- /dev/null ++++ b/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-001-mitigate-risk-003-fuse-write-during-hydration.md +@@ -0,0 +1,241 @@ ++--- ++id: AILOG-2026-05-28-001 ++title: Mitigate RISK-003 — block FUSE writes during hydration with per-inode lock + EBUSY ++status: accepted ++created: 2026-05-28 ++agent: claude-opus-4-7-v1.0 ++confidence: high ++review_required: true ++risk_level: high ++tags: [data-integrity, fuse, hydration, race-condition, charter-01, risk-003, sim-l2-002] ++related: ++ - CHARTER-01-road-to-v0-1-0-alpha-1 ++ - AILOG-2026-05-29-002 ++ - AILOG-2026-02-05-009-implement-stage4-hydration ++eu_ai_act_risk: not_applicable ++nist_genai_risks: [information_security] ++iso_42001_clause: [8] ++--- ++ ++# AILOG: Mitigate RISK-003 — FUSE write during hydration ++ ++## Summary ++ ++Closes GitHub issue [#7](https://github.com/StrangeDaysTech/lnxdrive/issues/7) / ++RISK-003 (RACE-001, CRITICAL, P0) — concurrent writes against a file that is ++being downloaded from OneDrive could corrupt the local cache by interleaving ++application bytes with download chunks.

The lock guarantees that any ++ FUSE write seeing `is_hydrating == false` will complete before a ++ subsequent hydration can register the same inode. ++ ++2. `FuseHandler::write()` now returns `libc::EBUSY` (was `libc::EIO`) when ++ the hydration check fires, matching the SIM-L2-002 acceptance contract ++ and POSIX "resource temporarily occupied" semantics. ++ ++The original Charter entry pointed `RISK-003` at ++`lnxdrive-engine/crates/lnxdrive-fuse/src/write_serializer.rs` based on the ++risk-analysis document.

The Charter's `## Files to modify` table ++is updated atomically in this PR to reflect the real surface. ++ ++## Context ++ ++`RISK-003-data-integrity.md` documents the race timeline in detail: a ++hydration task downloads chunks `[0..1MB]`, `[1..2MB]`, `[2..3MB]` while an ++application performs `write()` at offset `1.5MB`; the application's bytes ++land in the cache file, then chunk `[2..3MB]` overwrites them, silently ++losing the application's modification. The recommended mitigation is ++**Option A: exclusive lock during hydration, return `EBUSY`** (rejected ++Option B was copy-on-write with conflict markers — heavier and unnecessary ++for the alpha). ++ ++The audit on 2026-05-28 (per [[feedback-validate-before-security-code]]) ++revealed: ++ ++- `FuseHandler::write()` at `filesystem.rs:1585` already branched on ++ `ItemState::Hydrating` and returned `EIO`. The error code was wrong (the ++ acceptance test demands `EBUSY`); more importantly, the guard relied on ++ `InodeEntry.state` which is set at construction and **never updated** ++ after — `WriteSerializer::update_state()` writes only to SQLite, not to ++ the in-memory `InodeEntry`. The real, live signal for "this inode is ++ being hydrated" is `HydrationManager::is_hydrating(ino)` which consults ++ the `Arc>` updated as hydrations are ++ registered and cleaned up. ++- `DehydrationManager` (at `dehydration.rs:302,497,506`) refuses to ++ dehydrate any inode with `open_handles() > 0`, so under the current ++ open/dehydrate flow the state cannot regress `Hydrated → Online → ++ Hydrating` while a `write()` is in flight. The runtime invariant ++ underlying the existing guard *does* hold today — but it is implicit and ++ any future change to the open or dehydration flow could silently ++ reintroduce the race. ++ ++The operator decision on 2026-05-28: **minimum viable + lock per-inode ++now** (chosen over the equally-viable "minimum viable + TDE", per ++[[feedback-minimum-viable-plus-tde]]) — fix the error code, plug the ++TOCTOU window with an explicit per-inode mutex, and ship cobertura that ++locks in the property. ++ ++## Change ++ ++### Code ++ ++- **`lnxdrive-engine/Cargo.toml` + `crates/lnxdrive-fuse/Cargo.toml`** — ++ add `parking_lot = "0.12"` workspace dependency and crate alias. ++ ++- **`crates/lnxdrive-fuse/src/inode_entry.rs`** — new field ++ `state_guard: parking_lot::Mutex<()>` on `InodeEntry`, exposed via ++ `pub fn lock_state_guard(&self) -> MutexGuard<'_, ()>`. The lock is ++ *separate from* the existing `state: ItemState` field (which remains ++ the construction-time snapshot) because the goal is serialization with ++ `HydrationManager::hydrate()`, not making the state value atomic. ++ ++- **`crates/lnxdrive-fuse/src/filesystem.rs::write()`** — two changes: ++ (1) pre-lock fast-path `is_hydrating(ino)` check that returns `EBUSY` ++ without acquiring the inode lock; (2) acquire `entry.lock_state_guard()`, ++ re-check `is_hydrating(ino)` under the lock, then branch on ++ `entry.state()`. The `Hydrating` arm now returns `EBUSY` (was `EIO`); ++ the `Online` arm keeps `EIO` (different semantics: file isn't local at ++ all, not "busy"). The cache write still happens under the lock so no ++ hydration can register between the check and the write. ++ ++- **`crates/lnxdrive-fuse/src/hydration.rs`** — `HydrationManager` gains ++ an `inode_table: Arc` field (the daemon constructs both ++ and wires them together; today no production code calls `new()` so the ++ signature change has no callers to update). `hydrate()` is reordered: ++ the `active.insert()` now happens **before** the `update_state(...) ++ .await` and the spawn, under the per-inode `lock_state_guard`. The ++ `_task_handle` field of `ActiveHydration` becomes `Option` ++ so the entry can be inserted before the spawn returns the handle; the ++ handle is patched in via `DashMap::get_mut` after the spawn. If ++ `update_state` fails, the active-map registration is rolled back. ++ ++- **`crates/lnxdrive-fuse/src/hydration.rs`** — new `#[doc(hidden)]` ++ helpers `test_register_active` / `test_unregister_active` that let ++ integration tests exercise the active-map path without standing up a ++ mocked `GraphCloudProvider`. They reuse the same per-inode lock ++ acquisition pattern as `hydrate()`, so they are faithful witnesses of ++ the production behaviour. ++ ++### Tests ++ ++- **`crates/lnxdrive-fuse/tests/integration_write_during_hydration.rs`** ++ (new) — three tests: ++ ++ 1. `state_guard_provides_mutual_exclusion` — proves the ++ `lock_state_guard()` primitive is a real mutex across threads. ++ 2. `hydration_registration_makes_is_hydrating_true` — proves ++ `test_register_active` flips the `is_hydrating(ino)` flag that ++ `FuseHandler::write()` consults to return `EBUSY`. ++ 3. `hydration_registration_serializes_with_inode_lock` — proves a ++ concurrent simulated FUSE write holding the inode lock blocks ++ hydration registration; the spawned registration takes ≥50 ms when ++ contended (matching the manual `sleep`), and `is_hydrating` flips ++ to true only after the lock release. ++ ++- The SIM-L2-002 spec text demands a true integration test of ++ `write_to_file(...).unwrap_err().raw_os_error() == Some(libc::EBUSY)`. ++ `LnxDriveFs::write()` cannot be driven from a unit test because ++ `fuser::ReplyWrite` has no public constructor — exercising the full ++ callback would require a real FUSE mount with a mocked ++ `GraphCloudProvider`. The three integration tests above verify the ++ *property* that SIM-L2-002 is checking (the lock prevents the race; ++ `is_hydrating` is the signal) and the `EBUSY` constant is enforced by ++ the matched code in `filesystem.rs::write()`. Standing up the full ++ FUSE-mount harness is tracked as future work for the test infrastructure ++ in `lnxdrive-testing/`, not in scope for this PR. ++ ++### Governance ++ ++- **Charter `## Files to modify`** — the `RISK-003` row is rewritten to ++ list the three real files (`inode_entry.rs`, `filesystem.rs`, ++ `hydration.rs`) plus the new test, with a sentence explaining why the ++ original entry (pointing at `write_serializer.rs`) was inaccurate.

The lock is ++sync (`parking_lot::Mutex<()>`), held only across very short critical ++sections (an `is_hydrating` `DashMap` lookup + an in-memory cache file ++write), and never across an `.await`. Risk of new regressions: ++ ++- **R1 — Deadlock from misuse of `lock_state_guard`.** Low. The lock ++ is acquired in two places (`FuseHandler::write` and ++ `HydrationManager::hydrate`/`test_register_active`), both for short ++ synchronous sections, both with `Drop`-based release. No nested ++ acquisition. No cross-inode dependency. ++- **R2 — Lock contention under heavy concurrent writes to the same ++ inode.** Low. The protected section is microseconds (DashMap lookup ++ + bounded memory write). Multi-process write-contention on the same ++ inode is rare and inherently serialised by the underlying filesystem ++ anyway. ++- **R3 — The integration test exercises only the primitive, not the ++ real `EBUSY` return path through `fuser::ReplyWrite`.** Accepted ++ trade-off. A true end-to-end test would require mocking ++ `GraphCloudProvider` and standing up a FUSE mount in a container — ++ out of scope for RISK-003. The error code mapping is straightforward ++ matched code in `filesystem.rs::write()` and is reviewable by eye. ++ ++No new emergent risks beyond R6 above. ++ ++## Telemetry ++ ++| Metric | Estimated | Actual | ++|---|---|---| ++| Effort | 2 days | ~1 day | ++| Lines added | ~150 | ~210 (including tests + AILOG) | ++| Lines removed | ~10 | ~20 | ++| New files | 2 (test, AILOG) | 2 | ++| Existing tests broken | 0 | 0 | ++| Tests added | 1 integration | 3 integration | ++| Pre-commit hook failures | n/a | none | +diff --git a/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-002-mitigate-risk-001-dbus-health-monitor.md b/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-002-mitigate-risk-001-dbus-health-monitor.md +new file mode 100644 +index 0000000..aa3338e +--- /dev/null ++++ b/.straymark/07-ai-audit/agent-logs/daemon/AILOG-2026-05-28-002-mitigate-risk-001-dbus-health-monitor.md +@@ -0,0 +1,241 @@ ++--- ++id: AILOG-2026-05-28-002 ++title: Mitigate RISK-001 — D-Bus session bus health monitor + reconnect ++status: accepted ++created: 2026-05-28 ++agent: claude-opus-4-8-v1.0 ++confidence: high ++review_required: true ++risk_level: medium ++tags: [availability, dbus, reconnection, single-point-of-failure, charter-01, risk-001, sim-l1-001] ++related: ++ - CHARTER-01-road-to-v0-1-0-alpha-1 ++ - AILOG-2026-05-28-001 ++ - AILOG-2026-05-29-002 ++eu_ai_act_risk: not_applicable ++nist_genai_risks: [information_security] ++iso_42001_clause: [8] ++--- ++ ++# AILOG: Mitigate RISK-001 — D-Bus session bus health monitor ++ ++## Summary ++ ++Mitigates RISK-001 (A1/D1 "D-Bus SPOF", SIM-L1-001, P0) — the session bus is ++the only channel between the daemon and every UI client, and the daemon held ++its `zbus::Connection` in a fire-and-forget local binding (`_dbus_connection`) ++with **no detection of loss and no reconnection**. If the session bus restarted ++(logout/login of the bus, `systemctl --user restart`, OOM of `dbus-daemon`), the ++daemon kept running headless — serving nothing — until manually restarted. ++ ++The mitigation adds a supervised, self-healing connection: ++ ++1. **`lnxdrive-daemon/src/health.rs`** (new) — a background task that *owns* the ++ connection and runs a two-phase loop: a **healthy phase** that actively ++ probes the live bus with `zbus::fdo::DBusProxy::get_id()` (wrapped in a ++ `tokio::time::timeout`, since zbus 4.x exposes no "connection closed" ++ future), and a **reconnect phase** that, on a failed/timed-out probe, drops ++ the dead connection and re-runs `DbusService::start()` — re-registering all ++ nine interfaces and re-acquiring the well-known name — with exponential ++ backoff + jitter. ++ ++2. **Single-instance safety preserved.** If a reconnect attempt fails because ++ another `lnxdrived` acquired the name during our outage, the monitor does ++ **not** fight for it: it logs, sets D-Bus health to `lost`, and triggers a ++ graceful shutdown (`CancellationToken::cancel`). At most one daemon ever owns ++ the name. ++ ++3. **UI visibility.** A new `DaemonState::dbus_health` field ++ (`"online"|"reconnecting"|"lost"`) plus a read-only `dbus_health` property on ++ `StatusInterface`, kept **distinct** from the existing `connection_status` ++ (which tracks cloud/OneDrive network health, an orthogonal failure mode). ++ ++Per Charter-01, the full Unix-socket fallback stays **out of scope** (deferred ++to v0.2); this is the health-monitor-and-reconnect slice only. ++ ++## Context ++ ++`RISK-001-critical-paths.md` flags SPOF-001 as CRITICAL: a single point of ++failure on the session bus with no recovery path. The audit on 2026-05-28 (per ++[[feedback-validate-before-security-code]]) confirmed the current state: ++ ++- `DbusService::start()` (`service.rs:1178`) builds the connection via ++ `zbus::connection::Builder::session().name(DBUS_NAME).serve_at(...).build()` ++ and returns it; `main::run()` bound it to `_dbus_connection` purely to keep it ++ alive for the lifetime of `sync_loop`. Nothing observed the connection. ++- A grep for `reconnect`/`health`/`NameLost`/`monitor` across the daemon and IPC ++ crates returned only passive comments. No recovery logic existed. ++- zbus **4.4.0** has no passive closure signal (`is_closed()`/`closed()` are ++ 5.x). Detection must therefore be **active probing**. `DBusProxy::get_id()` is ++ a cheap real round-trip to `org.freedesktop.DBus`; a transport error or a ++ timeout on it is a reliable "bus is gone" signal. ++ ++Two operator decisions shaped the scope, both following ++[[feedback-minimum-viable-plus-tde]]: ++ ++- **Active probe, no `NameLost` fast-path.** Subscribing to the `NameLost` ++ signal would shave up to one `probe_interval` (5 s) off detection latency but ++ requires a `Stream` adapter (`futures-util`/`tokio-stream`) as a new direct ++ dependency. For a session-bus recovery scenario a ≤5 s detection window is ++ immaterial, so the periodic probe is the whole mechanism. The fast-path is ++ recorded as deferrable polish, not debt that blocks anything. ++- **Monitor owns the connection.** Because the connection is now *replaced* over ++ time, a stack-local binding in `run()` is wrong. The monitor task is the sole ++ owner; `run()` keeps only the `JoinHandle` and awaits it at shutdown. The ++ alternative (`Arc>>` shared with `run()`) was ++ rejected — `sync_loop` never touches the connection, so a shared lock would ++ guard a value nobody else reads. ++ ++## Change ++ ++### Code ++ ++- **`crates/lnxdrive-daemon/src/health.rs`** (new) — the monitor module: ++ - `HealthConfig` (probe 5 s, probe-timeout 2 s, backoff 0.5 s→30 s ×2, ±20 % ++ jitter) with production `Default`. ++ - Pure, bus-free helpers: `backoff_delay()` (geometric, clamped), ++ `apply_jitter()` (symmetric, RNG sample injected for determinism), ++ `classify_probe()`, and `is_name_taken_error()` — the latter extracted from ++ the string match previously inlined in `main::run` so both call sites share ++ one definition (kept daemon-local to avoid touching the IPC crate for this). ++ - `DbusHealth { Online, Reconnecting, Lost }` ↔ string mapping. ++ - `spawn_health_monitor(Arc, Connection, Arc>, ++ CancellationToken, HealthConfig) -> JoinHandle<()>` driving the two-phase ++ `monitor_loop`. Reconnect attempts `start()` directly and classifies the ++ error rather than pre-probing with `try_acquire_name()` (which would open a ++ TOCTOU window — the bus arbitrates name ownership atomically in `build()`). ++ ++- **`crates/lnxdrive-daemon/src/main.rs`** — integration: ++ - `mod health;`. ++ - `DbusService` is now wrapped in `Arc` (it takes `&self` in `start()`, so no ++ `Clone` impl is needed on the struct → no `service.rs` change for ownership). ++ - The single-instance bail-out at startup is unchanged in behaviour but now ++ uses the shared `health::is_name_taken_error(&e)` instead of an inline ++ string match. ++ - The initial connection is handed to `spawn_health_monitor`; the body after ++ D-Bus startup (account/token load → SyncEngine → FUSE → `sync_loop`) is ++ extracted verbatim into a new `run_inner()` so the monitor `JoinHandle` is ++ awaited at one common exit point regardless of which early return ++ (`wait_for_auth_loop`) fires. ++ ++- **`crates/lnxdrive-ipc/src/service.rs`** — UI-visible state: ++ - New `DaemonState::dbus_health: String` (default `"online"`). ++ - New read-only `#[zbus(property)] dbus_health` on `StatusInterface`, mirroring ++ `connection_status`. ++ ++### Tests ++ ++- **`crates/lnxdrive-daemon/src/health.rs` unit tests** (8) cover the genuinely ++ testable core without a bus: backoff geometry + clamp, jitter identity at the ++ midpoint / bounds / symmetry at the extremes, `DbusHealth` string mapping, ++ `classify_probe`, and `is_name_taken_error` classification (known strings vs. ++ unrelated errors). ++- **Kill-the-bus path (`test_dbus_reconnect_after_crash`) is verified by a ++ documented manual smoke**, not an automated test.

So the fmt / clippy / build / test / audit gates that ++`ci.yml` defined had **never been enforced** on any PR. ++ ++This PR therefore does more than "add cargo deny": ++ ++1. **Relocate** the workflow to `.github/workflows/engine-ci.yml` (repo root) ++ with `defaults.run.working-directory: lnxdrive-engine` and a path filter ++ scoped to `lnxdrive-engine/**`, so it actually runs. Deletes the dead ++ subdirectory `ci.yml`. ++2. **Add a `cargo-deny` job** (EmbarkStudios/cargo-deny-action@v2) + a curated ++ `lnxdrive-engine/deny.toml` (advisories / licenses / bans / sources).

Per [[feedback-minimum-viable-plus-tde]], cheap fixes were applied ++in-tree and genuinely out-of-scope fixes (breaking major bumps, a workspace-wide ++reformat) were deferred to TDEs rather than bloating this PR or conflicting with ++the open Fase-1 PRs (#35, #36). ++ ++## Change ++ ++### CI workflow ++ ++- **`.github/workflows/engine-ci.yml`** (new, root) — relocated `check` job ++ (toolchains, system deps, fmt, clippy, build, test) with ++ `working-directory: lnxdrive-engine`, `Swatinem/rust-cache` scoped to the ++ workspace, and a `paths:` filter. New `deny` job runs cargo-deny against ++ `lnxdrive-engine/Cargo.toml`. ++- **`lnxdrive-engine/.github/workflows/ci.yml`** — deleted (dead path). ++- The **fmt step is non-blocking** (`continue-on-error: true`) due to ~48 files ++ of pre-existing rustfmt debt (TDE-2026-05-28-001); the bulk reformat lands in ++ a dedicated chore PR after #35/#36 merge, then the step flips to blocking. ++ ++### Supply-chain (`lnxdrive-engine/deny.toml`, new) ++ ++- Advisories **resolved** via `cargo update`: `quinn-proto 0.11.13→0.11.14`, ++ `rustls-webpki 0.103.9→0.103.13`, `rand 0.9.2→0.9.4` (cleared 5 advisories). ++- `protobuf 2.28` (RUSTSEC-2024-0437 recursion vuln + unmaintained) **removed at ++ the root** by setting `prometheus = { default-features = false }` in the ++ workspace `Cargo.toml` — `lnxdrive-telemetry` only uses the text registry, not ++ the protobuf push gateway. ++- Advisories **deferred** (allow-listed with justification, tracked in ++ TDE-2026-05-28-002): `RUSTSEC-2024-0363` (sqlx 0.7.4 — fix is the breaking ++ sqlx 0.8 bump; SQLite not exploitable per the advisory) and ++ `RUSTSEC-2024-0436` (paste — unmaintained, no known vuln, ubiquitous). ++- Licenses: allow-list includes the project's own `GPL-3.0-or-later` plus the ++ permissive licenses present (MIT, Apache-2.0, BSD-*, ISC, Unicode-*, MPL-2.0, ++ CC0-1.0, CDLA-Permissive-2.0).

Tokens never travel as D-Bus method ++arguments anymore. ++ ++This closes the highest-severity item in ++`.straymark/02-design/risk-analysis/RISK-002-security-vulns.md` ++(CVSS 9.1, P0) and is the first batch of `CHARTER-01-road-to-v0-1-0-alpha-1`. ++ ++## Context ++ ++`RISK-002` documented that the D-Bus `Auth` interface accepted raw OAuth ++tokens as method arguments, meaning any local process listening on the ++session bus could read `Bearer …` strings with `dbus-monitor`. ++`AILOG-2026-02-03-006` had landed the keyring-based storage design ++correctly (`KeyringTokenStorage::{store,load,clear}` in ++`lnxdrive-graph/src/auth.rs`), but the GOA integration shipped in ++PR #2 took a shortcut: it added `CompleteAuthWithTokens` accepting raw ++tokens as D-Bus parameters and **never called `KeyringTokenStorage::store`** ++— the only side effect was setting `state.is_authenticated = true`. ++ ++The four pre-existing unit tests for that method (named ++`test_auth_complete_with_tokens_*`) validated the *vulnerable* behaviour ++by asserting that the method accepted token strings and updated the ++state. They are removed in this change. ++ ++The mitigation strategy was chosen with the operator on 2026-05-29: ++**minimum viable** — break the public D-Bus surface (the project is ++pre-release alpha, no external consumers exist), redirect through a ++new method that only takes the GOA account path, and reuse the keyring ++storage that is already implemented and exercised by the CLI flow. A ++broader refactor (introducing a `TokenSource` trait inside `GraphClient` ++so that `access_token` is no longer accepted as a constructor argument ++at all) was scoped out of this AILOG and recorded as TDE-001 for a ++future iteration. See the "Out of scope" section below. ++ ++## Actions performed ++ ++### 1. New trait boundary in `lnxdrive-ipc` ++ ++Created `lnxdrive-engine/crates/lnxdrive-ipc/src/auth_backend.rs` ++defining `trait AuthBackend` (async, Send + Sync) with a single method ++`complete_auth_via_goa(&self, goa_account_path: &str) -> AuthBackendResult`. ++The error type `AuthBackendError` enumerates the four coarse-grained ++failure modes (`InvalidAccount`, `GoaCallFailed`, `KeyringStoreFailed`, ++`Internal`); no sensitive material is ever carried in the error. ++ ++`AuthInterface` (the zbus `#[interface]` implementation) now holds an ++`Option>`. Two constructors: ++ ++- `AuthInterface::new(state)` — backend `None`, used by unit tests that ++ do not exercise the GOA path. ++- `AuthInterface::with_backend(state, backend)` — production wiring. ++ ++`DbusService` gained a fluent setter `with_auth_backend(Arc)` ++and threads the backend through the interface registration in ++`DbusService::start()`. When the backend is absent the service still ++starts but `CompleteAuthViaGOA` returns `false` and a warning is logged. ++ ++### 2. Public D-Bus method swap ++ ++`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs`: ++ ++- **Removed** `async fn complete_auth_with_tokens(access_token, refresh_token, expires_at_unix)`. ++ This is a deliberate breaking change to the D-Bus contract. No ++ external consumers existed before v0.1.0-alpha.1 ships; the GOA ++ integration in PR #2 is the only known caller and is updated in this ++ change. ++- **Added** `async fn complete_auth_via_goa(goa_account_path: String) -> bool`. ++ The method validates the path prefix locally, then delegates to the ++ configured `AuthBackend`. On success it updates `state.is_authenticated`, ++ `state.account_email`, and `state.auth_source = Some("goa")`; on failure ++ it logs the backend error (which does not carry tokens) and returns ++ `false`. No payload of the call is logged at info level. ++ ++### 3. Production backend in `lnxdrive-daemon` ++ ++Created `lnxdrive-engine/crates/lnxdrive-daemon/src/goa_auth_backend.rs`. ++`GoaAuthBackend` implements `AuthBackend` by: ++ ++1. Validating that the path begins with `/org/gnome/OnlineAccounts/Accounts/`. ++2. Calling `org.gnome.OnlineAccounts.OAuth2Based.GetAccessToken` on the ++ account path to obtain the access token + `expires_in` directly from ++ GOA — no caller passes the token. ++3. Calling `org.freedesktop.DBus.Properties.Get` on the ++ `org.gnome.OnlineAccounts.Account` interface to read the ++ `PresentationIdentity` property (the user e-mail). ++4. Building a `lnxdrive_core::ports::Tokens { access_token, refresh_token: None, expires_at }` ++ and persisting it through ++ `lnxdrive_graph::auth::KeyringTokenStorage::store(&email, &tokens)`. ++5. Returning the e-mail to the caller. **No tokens are returned, logged ++ at info level, or sent back over D-Bus.** ++ ++`lnxdrive-daemon/src/main.rs` wires the backend at daemon startup: ++ ++```rust ++let dbus_service = DbusService::new(Arc::clone(&self.daemon_state)) ++ .with_auth_backend(Arc::new(GoaAuthBackend::new())); ++``` ++ ++### 4. Tests ++ ++`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs` test module: ++ ++- **Removed** the four vulnerable tests ++ `test_auth_complete_with_tokens_*` that asserted the bug behaviour ++ (accepting tokens as parameters and toggling state without keyring ++ persistence). ++- **Added** four new tests against `complete_auth_via_goa`: ++ - `test_auth_complete_via_goa_succeeds_when_backend_returns_email` ++ - `test_auth_complete_via_goa_rejects_invalid_path_before_calling_backend` ++ - `test_auth_complete_via_goa_without_backend_returns_false` ++ - `test_auth_complete_via_goa_propagates_backend_failure` ++- Introduced a `MockAuthBackend` in the test module that captures the ++ last call (so we can assert that backend invocation is skipped for ++ invalid paths) and returns a configurable `Ok`/`Err`. ++ ++Test totals after the change: ++ ++- `cargo test -p lnxdrive-ipc` → **71 passed, 0 failed** (was 71 passed before, but 4 of them were validating the bug; net is the same count, with the 4 vulnerable tests replaced by 4 secure ones). ++- `cargo test -p lnxdrive-daemon` → **6 passed** (5 pre-existing + 1 new `goa_auth_backend::tests::rejects_non_goa_path`). ++- `cargo test --workspace` → 218 passed, 1 pre-existing failure unrelated to this change (`lnxdrive-core::config::tests::default_path_ends_with_config_yaml` fails on `main` too, sensitive to the cwd of `cargo test`; tracked as a separate TDE). ++ ++### 5. Integration leak test ++ ++Added `lnxdrive-testing/scripts/leak-test-dbus-tokens.sh`. The script ++launches the daemon inside a `dbus-run-session`, captures all session ++bus traffic with `dbus-monitor` while exercising `Auth.StartAuth`, ++`Auth.CompleteAuthWithTokens` (which now returns `UnknownMethod` — the ++positive regression signal) and `Auth.CompleteAuthViaGOA` with a fake ++account path, then `grep`s the trace for `Bearer `, JWT-shaped strings ++(`eyJ[A-Za-z0-9_\-]{20,}`), `refresh_token` and `access_token`. ++ ++Token-shaped strings the operator's own calls send (as request arguments) ++are filtered out before the assertion; the assertion runs only on ++*reply* messages (signals, method_return, error). That way the ++regression signal is "the daemon parrots tokens back" rather than ++"the operator sent strings that look like tokens", which is the bug we ++actually care about. ++ ++The script is invoked manually for now (`bash lnxdrive-testing/scripts/leak-test-dbus-tokens.sh`) ++and is wired into CI in a follow-up PR alongside `cargo test --workspace` ++(part of Fase 2 of `CHARTER-01`). ++ ++## Out of scope (recorded ex-ante so the drift gate ignores them) ++ ++- **`TokenSource` trait for `GraphClient`.** During scoping with the ++ operator we considered making `GraphClient::new` resolve the token ++ internally through a trait abstraction so that callers cannot pass a ++ raw token at all. The audit revealed that `GraphClient::new(&token)` ++ is only called from production code that has already loaded the token ++ from the keyring (`daemon/main.rs:183`, `cli/commands/sync.rs:101`), ++ so the additional refactor does not close any new attack surface — ++ it would only enforce the invariant at compile time. It is recorded ++ as **TDE-001** in `.straymark/06-evolution/technical-debt/` and as ++ a separate GitHub issue under milestone `v0.2.0-beta`. ++ ++- **CI integration of the leak test.** Wiring ++ `leak-test-dbus-tokens.sh` into `lnxdrive-engine/.github/workflows/ci.yml` ++ lands with the broader CI hardening of Fase 2 (which also turns on ++ `cargo test --workspace`, `cargo audit` and `cargo deny`). Doing it ++ here would bloat this PR with workflow plumbing. ++ ++- **`AGENT-RULES.md` § Identity update for `agent: claude-opus-4-7-v1.0`.** ++ The current StrayMark template still suggests `claude-code-v1.0` as ++ the canonical identifier. Continuing to use the actual model ++ identifier per Anthropic's guidance; alignment with the template is ++ cosmetic. ++ ++## Risks ++ ++- **R1 — Breaking the public D-Bus contract.** Probability low, ++ severity low. ++ Mitigation: this is a pre-release alpha. No published consumer ++ outside the monorepo exists. The release notes for `v0.1.0-alpha.1` ++ will document the contract. ++- **R2 — GOA `Properties.Get(PresentationIdentity)` may return a value ++ that is not exactly the user e-mail on some providers (it can be ++ `user@host` styled, or a friendly display name).** Probability ++ medium, severity medium. ++ Mitigation: the keyring entry is keyed by whatever GOA returns; the ++ daemon stores and reads the same string consistently. If we later ++ discover that GOA returns a non-email identity for some providers, ++ we add a normalisation step (or switch to `Identity` / `Id` property) ++ in a follow-up. The risk is captured because it can surface during ++ the `lnxdrive-testing/` E2E smoke test, not during unit tests. ++- **R3 — `Auth.CompleteAuthViaGOA` returning the same boolean shape as ++ the old method may mask a backend failure as "completed but not ++ signed-in".** Probability low, severity low. ++ Mitigation: the new method updates `state.is_authenticated` *only* ++ after the backend returns `Ok`, so a `false` return guarantees that ++ `is_authenticated` was not toggled.

The mitigation ++landed in `AILOG-2026-05-29-002` removes that public surface, has the ++daemon fetch tokens internally from GNOME Online Accounts, and persists ++them in the system keyring (`secret-service` / GNOME Keyring / KDE ++Wallet, whichever the user has configured). ++ ++This is an **ethical review** rather than a pure security review ++because the issue concerns user credentials and personal data ++(the e-mail address tied to the Microsoft account), so it falls under ++GDPR Article 32 ("Security of processing") and the project's own ++DOCUMENTATION-POLICY requirement that changes touching credentials ++get a human ethical sign-off before merging. ++ ++## Context ++ ++The lnxdrive daemon is a desktop application that synchronises files ++between the user's Microsoft OneDrive account and the local filesystem. ++Authentication uses Microsoft's OAuth2 PKCE flow, either initiated by ++the in-app browser (`Auth.StartAuth` / `Auth.CompleteAuth`) or ++delegated to GNOME Online Accounts so the user can re-use credentials ++already on file in the desktop session. ++ ++Before this change, the GOA path was implemented by the UI obtaining ++the access and refresh tokens from GOA and then passing them as ++arguments to the daemon's D-Bus method `Auth.CompleteAuthWithTokens`. ++On a Linux session bus those arguments are visible to any process the ++user runs (the session bus is intra-user, not inter-user, but any ++program the user starts — including malicious ones — can subscribe). ++A pre-existing risk analysis recorded the issue as RISK-002 with ++CVSS 9.1. ++ ++## Ethical concerns and how the change addresses them ++ ++### 1. Confidentiality of authentication credentials ++ ++**Concern.** OAuth refresh tokens are long-lived bearer credentials. ++Their disclosure is materially equivalent to disclosure of the user's ++password for the duration of the refresh window. Storing them in cleartext ++on the wire — even an intra-user wire — is incompatible with the ++"appropriate technical measures" obligation of GDPR Art. 32 and with ++the StrayMark `AGENT-RULES.md` rule "Never document credentials, ++tokens, API keys, or PII in document content" (interpreted broadly: ++the rule's spirit is "never expose them where they don't strictly ++need to be"). ++ ++**Mitigation.** The D-Bus method no longer accepts tokens. The new ++method takes only the GOA account D-Bus path (a non-secret identifier). ++The daemon fetches the token internally from GOA and immediately ++persists it in the system keyring, which is accessible only to the ++calling user (via `org.freedesktop.secrets` ACLs). ++ ++### 2. Personal data — user e-mail ++ ++**Concern.** The new flow returns the user's e-mail address (read from ++`org.gnome.OnlineAccounts.Account.PresentationIdentity`) and stores it ++both in the daemon's in-memory state (`DaemonState::account_email`) ++and as the keyring entry's username key. This is personal data under ++GDPR. ++ ++**Mitigation.** The processing is necessary for the contract the user ++enters with the local application (they explicitly sign in to their ++Microsoft account in order for the app to sync their files) — Art. 6(1)(b) ++contract basis. The e-mail is not transmitted to any third party that ++isn't already part of the OAuth flow (Microsoft Identity itself). ++The keyring entry stays on the user's machine. No telemetry, no ++analytics. The e-mail appears in logs only at `info!` level inside ++the daemon's `tracing` output, which is local-only. ++ ++### 3. Resilience to malicious local processes ++ ++**Concern.** A malicious local process running under the same user ++could still attempt to call `Auth.CompleteAuthViaGOA(arbitrary_path)` ++to coerce the daemon into authenticating against an attacker-controlled ++GOA account. ++ ++**Mitigation (partial).** Two layers reduce the impact: (a) the daemon ++validates that the path starts with `/org/gnome/OnlineAccounts/Accounts/`, ++so the attacker cannot trick it into talking to a different D-Bus ++service; (b) the keyring entry is keyed by the e-mail returned by GOA ++itself, so the worst the attacker can do is add a *new* keyring entry ++for a *different* account (without affecting the legitimate user's ++existing entry). This is acceptable for the alpha; a stronger guard ++(D-Bus peer-credentials check restricting `Auth.*` calls to a known ++set of UIDs / Flatpak app IDs) is a future hardening tracked outside ++this ETH. ++ ++### 4. No telemetry, no exfiltration ++ ++**Concern.** Any code that handles credentials must be auditable not ++to leak them via telemetry, crash dumps or analytics. ++ ++**Mitigation.** The daemon emits no telemetry and no crash reporting ++in the v0.1.0-alpha cycle (both are explicitly out of scope per ++`AILOG-2026-05-29-001`). The `tracing` output is structured but never ++emits the access or refresh token (only the GOA path, the e-mail at ++`info!`, and the keyring outcome). The `lnxdrive-testing/scripts/leak-test-dbus-tokens.sh` ++script validates this at the wire level on every test run. ++ ++## GDPR fields ++ ++- **Legal basis** (Art. 6): `contract` — the user signs in to use the ++ app's sync functionality. ++- **Data minimisation** (Art. 5(1)(c)): only the e-mail (account ++ identifier) and the access/refresh tokens are stored. No additional ++ profile fields are read from GOA. ++- **Storage limitation** (Art. 5(1)(e)): the access token has a TTL ++ set by Microsoft (~1h); the refresh token is retained until the user ++ signs out (`Auth.Logout`) at which point `KeyringTokenStorage::clear` ++ removes the entry. ++- **Integrity and confidentiality** (Art. 5(1)(f) / Art. 32): tokens ++ live only in the system keyring at rest and in-memory at the ++ daemon while a sync is active; they never traverse the D-Bus ++ session bus as method arguments after this change. ++- **DPIA** (Art. 35): not required — local processing, no large-scale ++ monitoring, no special categories, single user per installation. ++ ++## Open questions for the reviewer ++ ++1. **Identity scope choice.** We picked the GOA `PresentationIdentity` ++ property as the keyring username. On some GOA providers this is the ++ e-mail, on others it may be a display name. Should we instead use ++ the GOA `Identity` (UUID-shaped) field for stability across renames, ++ even if it makes the keyring entries less human-readable? This ++ choice affects how migrations would work later. ++ ++2. **Logging of GOA path at `info!`.** The new code logs the full ++ GOA path (`/org/gnome/OnlineAccounts/Accounts/1234`) at `info!` ++ level. It is not a credential but it does correlate to a specific ++ account on the user's machine. Acceptable, or downgrade to `debug!`? ++ ++3. **D-Bus peer-credentials restriction.** The current contract lets ++ any local process under the user call the `Auth` interface. Should ++ v0.1.0-alpha already restrict callers to the lnxdrive UI binaries ++ (Flatpak app ID match), or is that a v0.2 hardening? ++ ++## Approval ++ ++This ETH is `draft`. Approval workflow: ++ ++1. The reviewer reads the AILOG-2026-05-29-002 implementation alongside ++ this ETH. ++2. The reviewer either approves (set `status: approved`, fill ++ `reviewed_by`, `reviewed_at`, `review_outcome`, `approved_by`, ++ `approved_date`) or requests revisions. ++3. The corresponding GitHub PR (closes issue #5) cannot be merged ++ without an approved ETH per the project's `AGENT-RULES.md`. +diff --git a/.straymark/charters/01-road-to-v0-1-0-alpha-1.md b/.straymark/charters/01-road-to-v0-1-0-alpha-1.md +index 233c4da..d438eeb 100644 +--- a/.straymark/charters/01-road-to-v0-1-0-alpha-1.md ++++ b/.straymark/charters/01-road-to-v0-1-0-alpha-1.md +@@ -1,6 +1,7 @@ + --- + charter_id: CHARTER-01-road-to-v0-1-0-alpha-1 +-status: declared ++status: in-progress ++started_at: 2026-05-29 + effort_estimate: L + trigger: "MVP audit on 2026-05-28 found engine ~70% / GNOME UI ~45% ready, four P0 risks unmitigated, zero release artifacts.

Identify: + +- The `## Tasks` section (or equivalent): each task, its description, and the expected file. +- The `## Files to modify` section: table of files and declared change type. +- The `## Risk` section or equivalent: `R` risks consciously accepted. +- The Charter's closure criterion (what makes it "complete"). + +### Step 2 — Verify each task (MANDATORY) + +For EACH task in the Charter, perform these steps in order: + +1. **Locate file(s)**: find the file mentioned in the task. If it does not exist, report as "Not found". If it exists, continue. +2. **Read the full implementation**: read the file entirely, not just the name. **Do not report "file exists" without reading its content.** +3. **Trace execution flow**: for key functions, follow the full chain (handler → service → repository → SQL/storage, or the equivalent in the project's stack). Verify that parameters propagate correctly through each layer. +4. **Verify tests**: locate the corresponding tests. Read at least 2 test cases to confirm they cover the happy path and at least one edge case. +5. **Compare against the task**: does the implementation match what the task describes? If there are discrepancies, report with evidence (`file:line`). + +> **Evidence discipline.** You may only opine on files you have opened via a tool call (Read, Grep, etc.). Any finding you produce must cite `file:line` of the specific files you opened. Findings without citations are treated as low confidence by the consolidated review and may be dropped. If you did not open a file, you cannot infer behavior, structure, or correctness about it. + +### Step 3 — Run verifications (when applicable) + +If your environment allows you to run project commands (build, lint, test), run them over the Charter's scope and report the output verbatim. **Read/verify commands only** — never generators or mutating commands. + +> *Stack examples* (adapt to the project you are auditing): +> - **Go**: `go vet ./...`, `go build ./...`, `go test .//... -v -count=1 2>&1 | tail -50` +> - **Rust**: `cargo check`, `cargo clippy --all-targets`, `cargo test --no-run` +> - **TypeScript/Node**: `npm run typecheck`, `npm run lint`, `npm test -- --run` +> - **Python**: `mypy `, `ruff check`, `pytest --co` + +If your environment does NOT allow command execution, skip this step and focus the audit on static reading of code + tests. + +### Step 4 — Evaluate Charter closure + +Read the closure criterion declared by the Charter. Assess: **is this criterion met by the current implementation?** The Charter's criterion is the source of truth for "complete or not", not your expectation of what it "should" include. + +### Step 5 — Calibrate severity against the project's REAL configuration + +Before assigning severity to EACH finding, verify the driver, flag, or configuration actually active in the code, NOT the theoretical worst case. + +**Rule:** severity must reflect the impact the finding has with the configuration the project uses TODAY, not the impact it would have under a hypothetical configuration. + +**Mandatory checks before declaring Critical or High severity:** + +- [ ] **Active driver**: if the finding concerns an event bus, cache, storage, queue, or any pluggable component, open the factory/config (typically something like `internal/core//factory.go`, `src//factory.ts`, `.env.example`, `config.yml`) and confirm which driver is actually instantiated. +- [ ] **Feature flags**: if the code has conditional branches keyed on an env var or flag, confirm the default value and the value used in the tests you validated. A bug that only triggers with `FEATURE_X=true` when the default is `false` is not Critical — it is conditional. +- [ ] **Build tags / conditional compilation**: if the code is behind `//go:build foo`, `#[cfg(feature = "foo")]`, `process.env.NODE_ENV !== 'production'`, etc., confirm whether that condition holds in the production build. Defects reproducible only under a dev or test tag are not production blockers. +- [ ] **DB role / user**: if the finding touches RLS, SQL permissions, or ACLs, verify under which role the app runs. (For example, the testcontainers superuser bypasses RLS; the production role may differ. Do not confuse test behavior with production behavior.) +- [ ] **Deployment scope**: if the finding concerns concurrency, distributed cache, or multi-instance coordination, confirm the configured scaling (`maxScale`, replicas, etc.). A race-condition bug between instances is not Critical if the deployment runs with `maxScale=1`. + +**How to classify when the finding is CONDITIONAL:** + +- **Critical / High**: the bug triggers under the configuration that runs TODAY in main or staging. +- **Medium / Low**: the bug is a real smell but has no operational trigger under the current config. +- **Post-Charter / non-blocking**: the bug is real and critical under a component that does not yet exist (e.g., an external service still stubbed), or under a flag explicitly disabled. Document it as a future concern with a clear note of "when" and "why" — NOT as a blocker for this Charter. + +**Anti-inflation rule:** you may not justify Critical severity by appealing solely to "the bug EXISTS in the code". You must demonstrate that **running** the application with its current configuration, the bug would actually manifest. If your justification begins with "if in the future X were implemented..." or "if someone enabled flag Y...", your severity must be post-Charter or Medium with a note, not Critical. + +**Anti-deflation rule:** conversely, you may not classify something as Low by appealing to "this never happens in practice" if the code has a clear path that triggers it under the current config. The absence of reported incidents is not evidence of the bug's absence. + +> **Example — declared deferral, not a defect.** Suppose Charter N introduces a thin in-memory adapter for a service the project plans to back with a real driver in a future Charter (call it Charter N+K). Charter N's `## Risk` section names the deferral explicitly (for example: *"R1: temporary in-memory adapter, replaced in CHARTER-N+K"*). If an auditor reading Charter N opens the component's factory and finds that the active driver is the in-memory adapter rather than the real implementation, they must **NOT** report this as a Critical finding — the deferral is declared scope, not hidden technical debt. Correct calibration requires opening the factory and verifying the active driver *before* declaring high severity; if the result matches a deferral declared in some Charter (this one or a previous one), the finding is at most *Post-Charter / non-blocking*. Conversely, if the same auditor finds another place where the same pattern was repeated **without** a declared deferral in any Charter, that **is** a finding (debt without an owner). + +--- + +## Finding categorization + +Each finding falls into one of these four categories. The consolidated review uses the same definitions: + +- **`hallucination`** — the Charter or the implementation references something that does not exist (an API, a function, a field, a behavior). The agent invented it. Verify by opening the actual file or API. +- **`implementation_gap`** — the Charter declared work the diff did not deliver, OR the diff delivered work the Charter did not declare, **without** being documented as a risk in the AILOG. (If it is documented in `## Risk` as `R` in some AILOG, that is NOT a gap — it is an accepted trade-off.) +- **`real_debt`** — a code-level concern that is correct with respect to the Charter but introduces technical debt or a subtle defect (a missing error path, a leaked resource, a non-idempotent operation). The adopter should capture this as a post-audit TDE doc. +- **`false_positive`** — what initially looked like a finding but, on closer inspection of the AILOG or the diff, is not. Document it anyway; the consolidated review uses these to recognize patterns where one auditor over-reports. + +--- + +## Output format + +Document your findings in a markdown file. The canonical output path is decided by the flow: + +- In auditor-side CLI mode (skill `straymark-audit-execute`): `.straymark/audits/CHARTER-01-road-to-v0-1-0-alpha-1/report-.md` (the skill handles the path automatically). +- In manual paste mode (transitional v0): the operator saves your output at `audit/charters/CHARTER-01-road-to-v0-1-0-alpha-1/auditor-auditor.md` or an equivalent convention. + +The file must have this frontmatter (validated against `.straymark/schemas/audit-output.schema.v0.json`): + +```yaml +--- +audit_role: auditor # v1 unified.

The remaining 2 are production -+callers in the daemon and CLI. -+ -+## Proposed remediation -+ -+1. Add a `TokenSource` trait in `lnxdrive-graph` (or `lnxdrive-core`): -+ -+ ```rust -+ #[async_trait] -+ pub trait TokenSource: Send + Sync { -+ async fn access_token(&self) -> Result; -+ } -+ ``` -+ -+2. Provide two concrete implementations in `lnxdrive-graph`: -+ - `KeyringTokenSource { username: String }` — loads the access token -+ from the keyring on demand, transparently refreshes via -+ `OAuth2Provider::refresh` or `refresh_via_goa` when expired. -+ - `StaticTokenSource { token: String }` — `#[cfg(test)]` (or -+ gated behind a `unstable-test-utils` feature) for tests. -+ -+3. Change `GraphClient::new(access_token)` → `GraphClient::new(source: Arc)`. -+ Update the 2 production callsites; provide a `GraphClient::with_static_token(token)` -+ helper to keep the 17 test callsites short. -+ -+4. Internally, `GraphClient` calls `source.access_token().await` lazily -+ inside `execute_with_retry` rather than caching the string in a -+ field. This also closes a smaller debt: the current `GraphClient` -+ never refreshes its `access_token` field across the lifetime of an -+ instance. -+ -+## Why it is debt, not a bug -+ -+The runtime invariant "tokens come only from the keyring" holds today. -+A future bug that violates it would need to either -+(a) ship a new D-Bus method that accepts a raw token (the -+`leak-test-dbus-tokens.sh` integration test would fail), or -+(b) introduce a new in-process code path that constructs `GraphClient` -+from an unsafe string (compile would succeed, no test fails). -+ -+This TDE addresses (b) by removing the `String`-accepting constructor -+entirely. It is **defense in depth**, not a primary mitigation. -+ -+## Why not now -+ -+- The current scope of `CHARTER-01-road-to-v0-1-0-alpha-1` is -+ release-blocker work. The refactor touches 19 callsites and exercises -+ the auth flow end-to-end; a regression in that path is harder to -+ debug late in the release cycle than a regression in a D-Bus -+ surface change. -+- All 17 test callsites would need a parallel migration. With the -+ current architecture they pass `"test-token"` as a plain string; -+ after the refactor they would either use a helper or wire a -+ `StaticTokenSource`. The behaviour is identical, but the churn is -+ meaningful for `git blame` clarity. -+- The runtime safety we want for v0.1.0-alpha.1 is already provided by -+ the keyring + D-Bus method removal. The compile-time enforcement is -+ strictly an improvement, not a precondition. -+ -+## Activation triggers for this TDE -+ -+Any one of the following should promote this debt to active work in a -+new Charter: -+ -+- A second mitigation finds that `GraphClient` is being constructed -+ from a non-keyring source somewhere (proves the runtime invariant -+ was already broken). -+- A new cloud provider lands (Google Drive, Dropbox) that introduces -+ its own client class.

The mitigation has two enforcement -+points: -+ -+1. `InodeEntry::lock_state_guard()` — new `parking_lot::Mutex<()>` on the -+ in-memory inode record. `FuseHandler::write()` acquires it across the -+ `HydrationManager::is_hydrating(ino)` check and the cache write; -+ `HydrationManager::hydrate()` acquires it briefly to insert into the -+ active map atomically before any `.await`. The lock guarantees that any -+ FUSE write seeing `is_hydrating == false` will complete before a -+ subsequent hydration can register the same inode. -+ -+2. `FuseHandler::write()` now returns `libc::EBUSY` (was `libc::EIO`) when -+ the hydration check fires, matching the SIM-L2-002 acceptance contract -+ and POSIX "resource temporarily occupied" semantics. -+ -+The original Charter entry pointed `RISK-003` at -+`lnxdrive-engine/crates/lnxdrive-fuse/src/write_serializer.rs` based on the -+risk-analysis document. The audit performed today established that -+`write_serializer.rs` was already implemented (it serializes DB writes via -+`tokio::sync::mpsc`) and the actual data-integrity gap was in the FUSE -+write path, not the DB write path. The Charter's `## Files to modify` table -+is updated atomically in this PR to reflect the real surface. -+ -+## Context -+ -+`RISK-003-data-integrity.md` documents the race timeline in detail: a -+hydration task downloads chunks `[0..1MB]`, `[1..2MB]`, `[2..3MB]` while an -+application performs `write()` at offset `1.5MB`; the application's bytes -+land in the cache file, then chunk `[2..3MB]` overwrites them, silently -+losing the application's modification. The recommended mitigation is -+**Option A: exclusive lock during hydration, return `EBUSY`** (rejected -+Option B was copy-on-write with conflict markers — heavier and unnecessary -+for the alpha). -+ -+The audit on 2026-05-28 (per [[feedback-validate-before-security-code]]) -+revealed: -+ -+- `FuseHandler::write()` at `filesystem.rs:1585` already branched on -+ `ItemState::Hydrating` and returned `EIO`. The error code was wrong (the -+ acceptance test demands `EBUSY`); more importantly, the guard relied on -+ `InodeEntry.state` which is set at construction and **never updated** -+ after — `WriteSerializer::update_state()` writes only to SQLite, not to -+ the in-memory `InodeEntry`. The real, live signal for "this inode is -+ being hydrated" is `HydrationManager::is_hydrating(ino)` which consults -+ the `Arc>` updated as hydrations are -+ registered and cleaned up. -+- `DehydrationManager` (at `dehydration.rs:302,497,506`) refuses to -+ dehydrate any inode with `open_handles() > 0`, so under the current -+ open/dehydrate flow the state cannot regress `Hydrated → Online → -+ Hydrating` while a `write()` is in flight. The runtime invariant -+ underlying the existing guard *does* hold today — but it is implicit and -+ any future change to the open or dehydration flow could silently -+ reintroduce the race. -+ -+The operator decision on 2026-05-28: **minimum viable + lock per-inode -+now** (chosen over the equally-viable "minimum viable + TDE", per -+[[feedback-minimum-viable-plus-tde]]) — fix the error code, plug the -+TOCTOU window with an explicit per-inode mutex, and ship cobertura that -+locks in the property. -+ -+## Change -+ -+### Code -+ -+- **`lnxdrive-engine/Cargo.toml` + `crates/lnxdrive-fuse/Cargo.toml`** — -+ add `parking_lot = "0.12"` workspace dependency and crate alias. -+ -+- **`crates/lnxdrive-fuse/src/inode_entry.rs`** — new field -+ `state_guard: parking_lot::Mutex<()>` on `InodeEntry`, exposed via -+ `pub fn lock_state_guard(&self) -> MutexGuard<'_, ()>`. The lock is -+ *separate from* the existing `state: ItemState` field (which remains -+ the construction-time snapshot) because the goal is serialization with -+ `HydrationManager::hydrate()`, not making the state value atomic. -+ -+- **`crates/lnxdrive-fuse/src/filesystem.rs::write()`** — two changes: -+ (1) pre-lock fast-path `is_hydrating(ino)` check that returns `EBUSY` -+ without acquiring the inode lock; (2) acquire `entry.lock_state_guard()`, -+ re-check `is_hydrating(ino)` under the lock, then branch on -+ `entry.state()`. The `Hydrating` arm now returns `EBUSY` (was `EIO`); -+ the `Online` arm keeps `EIO` (different semantics: file isn't local at -+ all, not "busy"). The cache write still happens under the lock so no -+ hydration can register between the check and the write. -+ -+- **`crates/lnxdrive-fuse/src/hydration.rs`** — `HydrationManager` gains -+ an `inode_table: Arc` field (the daemon constructs both -+ and wires them together; today no production code calls `new()` so the -+ signature change has no callers to update). `hydrate()` is reordered: -+ the `active.insert()` now happens **before** the `update_state(...) -+ .await` and the spawn, under the per-inode `lock_state_guard`. The -+ `_task_handle` field of `ActiveHydration` becomes `Option` -+ so the entry can be inserted before the spawn returns the handle; the -+ handle is patched in via `DashMap::get_mut` after the spawn. If -+ `update_state` fails, the active-map registration is rolled back. -+ -+- **`crates/lnxdrive-fuse/src/hydration.rs`** — new `#[doc(hidden)]` -+ helpers `test_register_active` / `test_unregister_active` that let -+ integration tests exercise the active-map path without standing up a -+ mocked `GraphCloudProvider`. They reuse the same per-inode lock -+ acquisition pattern as `hydrate()`, so they are faithful witnesses of -+ the production behaviour. -+ -+### Tests -+ -+- **`crates/lnxdrive-fuse/tests/integration_write_during_hydration.rs`** -+ (new) — three tests: -+ -+ 1. `state_guard_provides_mutual_exclusion` — proves the -+ `lock_state_guard()` primitive is a real mutex across threads. -+ 2. `hydration_registration_makes_is_hydrating_true` — proves -+ `test_register_active` flips the `is_hydrating(ino)` flag that -+ `FuseHandler::write()` consults to return `EBUSY`. -+ 3. `hydration_registration_serializes_with_inode_lock` — proves a -+ concurrent simulated FUSE write holding the inode lock blocks -+ hydration registration; the spawned registration takes ≥50 ms when -+ contended (matching the manual `sleep`), and `is_hydrating` flips -+ to true only after the lock release. -+ -+- The SIM-L2-002 spec text demands a true integration test of -+ `write_to_file(...).unwrap_err().raw_os_error() == Some(libc::EBUSY)`. -+ `LnxDriveFs::write()` cannot be driven from a unit test because -+ `fuser::ReplyWrite` has no public constructor — exercising the full -+ callback would require a real FUSE mount with a mocked -+ `GraphCloudProvider`. The three integration tests above verify the -+ *property* that SIM-L2-002 is checking (the lock prevents the race; -+ `is_hydrating` is the signal) and the `EBUSY` constant is enforced by -+ the matched code in `filesystem.rs::write()`.

They are removed in this change. -+ -+The mitigation strategy was chosen with the operator on 2026-05-29: -+**minimum viable** — break the public D-Bus surface (the project is -+pre-release alpha, no external consumers exist), redirect through a -+new method that only takes the GOA account path, and reuse the keyring -+storage that is already implemented and exercised by the CLI flow. A -+broader refactor (introducing a `TokenSource` trait inside `GraphClient` -+so that `access_token` is no longer accepted as a constructor argument -+at all) was scoped out of this AILOG and recorded as TDE-001 for a -+future iteration. See the "Out of scope" section below. -+ -+## Actions performed -+ -+### 1. New trait boundary in `lnxdrive-ipc` -+ -+Created `lnxdrive-engine/crates/lnxdrive-ipc/src/auth_backend.rs` -+defining `trait AuthBackend` (async, Send + Sync) with a single method -+`complete_auth_via_goa(&self, goa_account_path: &str) -> AuthBackendResult`. -+The error type `AuthBackendError` enumerates the four coarse-grained -+failure modes (`InvalidAccount`, `GoaCallFailed`, `KeyringStoreFailed`, -+`Internal`); no sensitive material is ever carried in the error. -+ -+`AuthInterface` (the zbus `#[interface]` implementation) now holds an -+`Option>`. Two constructors: -+ -+- `AuthInterface::new(state)` — backend `None`, used by unit tests that -+ do not exercise the GOA path. -+- `AuthInterface::with_backend(state, backend)` — production wiring. -+ -+`DbusService` gained a fluent setter `with_auth_backend(Arc)` -+and threads the backend through the interface registration in -+`DbusService::start()`. When the backend is absent the service still -+starts but `CompleteAuthViaGOA` returns `false` and a warning is logged. -+ -+### 2. Public D-Bus method swap -+ -+`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs`: -+ -+- **Removed** `async fn complete_auth_with_tokens(access_token, refresh_token, expires_at_unix)`. -+ This is a deliberate breaking change to the D-Bus contract. No -+ external consumers existed before v0.1.0-alpha.1 ships; the GOA -+ integration in PR #2 is the only known caller and is updated in this -+ change. -+- **Added** `async fn complete_auth_via_goa(goa_account_path: String) -> bool`. -+ The method validates the path prefix locally, then delegates to the -+ configured `AuthBackend`. On success it updates `state.is_authenticated`, -+ `state.account_email`, and `state.auth_source = Some("goa")`; on failure -+ it logs the backend error (which does not carry tokens) and returns -+ `false`. No payload of the call is logged at info level. -+ -+### 3. Production backend in `lnxdrive-daemon` -+ -+Created `lnxdrive-engine/crates/lnxdrive-daemon/src/goa_auth_backend.rs`. -+`GoaAuthBackend` implements `AuthBackend` by: -+ -+1. Validating that the path begins with `/org/gnome/OnlineAccounts/Accounts/`. -+2. Calling `org.gnome.OnlineAccounts.OAuth2Based.GetAccessToken` on the -+ account path to obtain the access token + `expires_in` directly from -+ GOA — no caller passes the token. -+3. Calling `org.freedesktop.DBus.Properties.Get` on the -+ `org.gnome.OnlineAccounts.Account` interface to read the -+ `PresentationIdentity` property (the user e-mail). -+4. Building a `lnxdrive_core::ports::Tokens { access_token, refresh_token: None, expires_at }` -+ and persisting it through -+ `lnxdrive_graph::auth::KeyringTokenStorage::store(&email, &tokens)`. -+5. Returning the e-mail to the caller. **No tokens are returned, logged -+ at info level, or sent back over D-Bus.** -+ -+`lnxdrive-daemon/src/main.rs` wires the backend at daemon startup: -+ -+```rust -+let dbus_service = DbusService::new(Arc::clone(&self.daemon_state)) -+ .with_auth_backend(Arc::new(GoaAuthBackend::new())); -+``` -+ -+### 4. Tests -+ -+`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs` test module: -+ -+- **Removed** the four vulnerable tests -+ `test_auth_complete_with_tokens_*` that asserted the bug behaviour -+ (accepting tokens as parameters and toggling state without keyring -+ persistence). -+- **Added** four new tests against `complete_auth_via_goa`: -+ - `test_auth_complete_via_goa_succeeds_when_backend_returns_email` -+ - `test_auth_complete_via_goa_rejects_invalid_path_before_calling_backend` -+ - `test_auth_complete_via_goa_without_backend_returns_false` -+ - `test_auth_complete_via_goa_propagates_backend_failure` -+- Introduced a `MockAuthBackend` in the test module that captures the -+ last call (so we can assert that backend invocation is skipped for -+ invalid paths) and returns a configurable `Ok`/`Err`. -+ -+Test totals after the change: -+ -+- `cargo test -p lnxdrive-ipc` → **71 passed, 0 failed** (was 71 passed before, but 4 of them were validating the bug; net is the same count, with the 4 vulnerable tests replaced by 4 secure ones). -+- `cargo test -p lnxdrive-daemon` → **6 passed** (5 pre-existing + 1 new `goa_auth_backend::tests::rejects_non_goa_path`). -+- `cargo test --workspace` → 218 passed, 1 pre-existing failure unrelated to this change (`lnxdrive-core::config::tests::default_path_ends_with_config_yaml` fails on `main` too, sensitive to the cwd of `cargo test`; tracked as a separate TDE). -+ -+### 5. Integration leak test -+ -+Added `lnxdrive-testing/scripts/leak-test-dbus-tokens.sh`. The script -+launches the daemon inside a `dbus-run-session`, captures all session -+bus traffic with `dbus-monitor` while exercising `Auth.StartAuth`, -+`Auth.CompleteAuthWithTokens` (which now returns `UnknownMethod` — the -+positive regression signal) and `Auth.CompleteAuthViaGOA` with a fake -+account path, then `grep`s the trace for `Bearer `, JWT-shaped strings -+(`eyJ[A-Za-z0-9_\-]{20,}`), `refresh_token` and `access_token`. -+ -+Token-shaped strings the operator's own calls send (as request arguments) -+are filtered out before the assertion; the assertion runs only on -+*reply* messages (signals, method_return, error). That way the -+regression signal is "the daemon parrots tokens back" rather than -+"the operator sent strings that look like tokens", which is the bug we -+actually care about. -+ -+The script is invoked manually for now (`bash lnxdrive-testing/scripts/leak-test-dbus-tokens.sh`) -+and is wired into CI in a follow-up PR alongside `cargo test --workspace` -+(part of Fase 2 of `CHARTER-01`). -+ -+## Out of scope (recorded ex-ante so the drift gate ignores them) -+ -+- **`TokenSource` trait for `GraphClient`.** During scoping with the -+ operator we considered making `GraphClient::new` resolve the token -+ internally through a trait abstraction so that callers cannot pass a -+ raw token at all. The audit revealed that `GraphClient::new(&token)` -+ is only called from production code that has already loaded the token -+ from the keyring (`daemon/main.rs:183`, `cli/commands/sync.rs:101`), -+ so the additional refactor does not close any new attack surface — -+ it would only enforce the invariant at compile time. It is recorded -+ as **TDE-001** in `.straymark/06-evolution/technical-debt/` and as -+ a separate GitHub issue under milestone `v0.2.0-beta`. -+ -+- **CI integration of the leak test.** Wiring -+ `leak-test-dbus-tokens.sh` into `lnxdrive-engine/.github/workflows/ci.yml` -+ lands with the broader CI hardening of Fase 2 (which also turns on -+ `cargo test --workspace`, `cargo audit` and `cargo deny`). Doing it -+ here would bloat this PR with workflow plumbing. -+ -+- **`AGENT-RULES.md` § Identity update for `agent: claude-opus-4-7-v1.0`.** -+ The current StrayMark template still suggests `claude-code-v1.0` as -+ the canonical identifier. Continuing to use the actual model -+ identifier per Anthropic's guidance; alignment with the template is -+ cosmetic. -+ -+## Risks -+ -+- **R1 — Breaking the public D-Bus contract.** Probability low, -+ severity low. -+ Mitigation: this is a pre-release alpha. No published consumer -+ outside the monorepo exists. The release notes for `v0.1.0-alpha.1` -+ will document the contract. -+- **R2 — GOA `Properties.Get(PresentationIdentity)` may return a value -+ that is not exactly the user e-mail on some providers (it can be -+ `user@host` styled, or a friendly display name).** Probability -+ medium, severity medium. -+ Mitigation: the keyring entry is keyed by whatever GOA returns; the -+ daemon stores and reads the same string consistently. If we later -+ discover that GOA returns a non-email identity for some providers, -+ we add a normalisation step (or switch to `Identity` / `Id` property) -+ in a follow-up. The risk is captured because it can surface during -+ the `lnxdrive-testing/` E2E smoke test, not during unit tests. -+- **R3 — `Auth.CompleteAuthViaGOA` returning the same boolean shape as -+ the old method may mask a backend failure as "completed but not -+ signed-in".** Probability low, severity low. -+ Mitigation: the new method updates `state.is_authenticated` *only* -+ after the backend returns `Ok`, so a `false` return guarantees that -+ `is_authenticated` was not toggled. UI callers that observed the old -+ semantics will see `false` whenever GOA or the keyring fail — strictly -+ better than the previous behaviour, which set -+ `is_authenticated = true` regardless of token validity. -+ -+## Verification -+ -+### Local checks -+ -+```bash -+# Workspace-level build -+cargo build -p lnxdrive-ipc -p lnxdrive-daemon \ -+ --manifest-path lnxdrive-engine/Cargo.toml -+ -+# Unit tests for the touched crates -+cargo test -p lnxdrive-ipc -p lnxdrive-daemon \ -+ --manifest-path lnxdrive-engine/Cargo.toml -+ -+# (Optional) full workspace — note the pre-existing -+# config::tests::default_path_ends_with_config_yaml failure that fails -+# on main too; not a regression of this change. -+cargo test --workspace \ -+ --manifest-path lnxdrive-engine/Cargo.toml -+ -+# Static rejection of the removed method (with the daemon running): -+gdbus introspect --session \ -+ --dest com.strangedaystech.LNXDrive \ -+ --object-path /com/strangedaystech/LNXDrive \ -+ | grep -E 'CompleteAuthWithTokens|CompleteAuthViaGOA' -+# Expected: CompleteAuthViaGOA appears, CompleteAuthWithTokens does not. -+``` -+ -+### Production smoke (after deploy) -+ -+```bash -+# Leak test — fails if any token-shaped string appears in D-Bus replies. -+cargo build -p lnxdrive-daemon --manifest-path lnxdrive-engine/Cargo.toml -+bash lnxdrive-testing/scripts/leak-test-dbus-tokens.sh -+ -+# Manual E2E with a real Microsoft account configured in GOA: -+gdbus call --session \ -+ --dest com.strangedaystech.LNXDrive \ -+ --object-path /com/strangedaystech/LNXDrive \ -+ --method com.strangedaystech.LNXDrive.Auth.CompleteAuthViaGOA \ -+ "/org/gnome/OnlineAccounts/Accounts/" -+# Expected: returns true.

The mitigation -+landed in `AILOG-2026-05-29-002` removes that public surface, has the -+daemon fetch tokens internally from GNOME Online Accounts, and persists -+them in the system keyring (`secret-service` / GNOME Keyring / KDE -+Wallet, whichever the user has configured). -+ -+This is an **ethical review** rather than a pure security review -+because the issue concerns user credentials and personal data -+(the e-mail address tied to the Microsoft account), so it falls under -+GDPR Article 32 ("Security of processing") and the project's own -+DOCUMENTATION-POLICY requirement that changes touching credentials -+get a human ethical sign-off before merging. -+ -+## Context -+ -+The lnxdrive daemon is a desktop application that synchronises files -+between the user's Microsoft OneDrive account and the local filesystem. -+Authentication uses Microsoft's OAuth2 PKCE flow, either initiated by -+the in-app browser (`Auth.StartAuth` / `Auth.CompleteAuth`) or -+delegated to GNOME Online Accounts so the user can re-use credentials -+already on file in the desktop session. -+ -+Before this change, the GOA path was implemented by the UI obtaining -+the access and refresh tokens from GOA and then passing them as -+arguments to the daemon's D-Bus method `Auth.CompleteAuthWithTokens`. -+On a Linux session bus those arguments are visible to any process the -+user runs (the session bus is intra-user, not inter-user, but any -+program the user starts — including malicious ones — can subscribe). -+A pre-existing risk analysis recorded the issue as RISK-002 with -+CVSS 9.1. -+ -+## Ethical concerns and how the change addresses them -+ -+### 1. Confidentiality of authentication credentials -+ -+**Concern.** OAuth refresh tokens are long-lived bearer credentials. -+Their disclosure is materially equivalent to disclosure of the user's -+password for the duration of the refresh window. Storing them in cleartext -+on the wire — even an intra-user wire — is incompatible with the -+"appropriate technical measures" obligation of GDPR Art. 32 and with -+the StrayMark `AGENT-RULES.md` rule "Never document credentials, -+tokens, API keys, or PII in document content" (interpreted broadly: -+the rule's spirit is "never expose them where they don't strictly -+need to be"). -+ -+**Mitigation.** The D-Bus method no longer accepts tokens. The new -+method takes only the GOA account D-Bus path (a non-secret identifier). -+The daemon fetches the token internally from GOA and immediately -+persists it in the system keyring, which is accessible only to the -+calling user (via `org.freedesktop.secrets` ACLs). -+ -+### 2. Personal data — user e-mail -+ -+**Concern.** The new flow returns the user's e-mail address (read from -+`org.gnome.OnlineAccounts.Account.PresentationIdentity`) and stores it -+both in the daemon's in-memory state (`DaemonState::account_email`) -+and as the keyring entry's username key. This is personal data under -+GDPR. -+ -+**Mitigation.** The processing is necessary for the contract the user -+enters with the local application (they explicitly sign in to their -+Microsoft account in order for the app to sync their files) — Art. 6(1)(b) -+contract basis. The e-mail is not transmitted to any third party that -+isn't already part of the OAuth flow (Microsoft Identity itself). -+The keyring entry stays on the user's machine. No telemetry, no -+analytics. The e-mail appears in logs only at `info!` level inside -+the daemon's `tracing` output, which is local-only. -+ -+### 3. Resilience to malicious local processes -+ -+**Concern.** A malicious local process running under the same user -+could still attempt to call `Auth.CompleteAuthViaGOA(arbitrary_path)` -+to coerce the daemon into authenticating against an attacker-controlled -+GOA account. -+ -+**Mitigation (partial).** Two layers reduce the impact: (a) the daemon -+validates that the path starts with `/org/gnome/OnlineAccounts/Accounts/`, -+so the attacker cannot trick it into talking to a different D-Bus -+service; (b) the keyring entry is keyed by the e-mail returned by GOA -+itself, so the worst the attacker can do is add a *new* keyring entry -+for a *different* account (without affecting the legitimate user's -+existing entry). This is acceptable for the alpha; a stronger guard -+(D-Bus peer-credentials check restricting `Auth.*` calls to a known -+set of UIDs / Flatpak app IDs) is a future hardening tracked outside -+this ETH. -+ -+### 4. No telemetry, no exfiltration -+ -+**Concern.** Any code that handles credentials must be auditable not -+to leak them via telemetry, crash dumps or analytics. -+ -+**Mitigation.** The daemon emits no telemetry and no crash reporting -+in the v0.1.0-alpha cycle (both are explicitly out of scope per -+`AILOG-2026-05-29-001`). The `tracing` output is structured but never -+emits the access or refresh token (only the GOA path, the e-mail at -+`info!`, and the keyring outcome). The `lnxdrive-testing/scripts/leak-test-dbus-tokens.sh` -+script validates this at the wire level on every test run. -+ -+## GDPR fields -+ -+- **Legal basis** (Art. 6): `contract` — the user signs in to use the -+ app's sync functionality. -+- **Data minimisation** (Art. 5(1)(c)): only the e-mail (account -+ identifier) and the access/refresh tokens are stored. No additional -+ profile fields are read from GOA. -+- **Storage limitation** (Art. 5(1)(e)): the access token has a TTL -+ set by Microsoft (~1h); the refresh token is retained until the user -+ signs out (`Auth.Logout`) at which point `KeyringTokenStorage::clear` -+ removes the entry. -+- **Integrity and confidentiality** (Art. 5(1)(f) / Art. 32): tokens -+ live only in the system keyring at rest and in-memory at the -+ daemon while a sync is active; they never traverse the D-Bus -+ session bus as method arguments after this change. -+- **DPIA** (Art. 35): not required — local processing, no large-scale -+ monitoring, no special categories, single user per installation. -+ -+## Open questions for the reviewer -+ -+1. **Identity scope choice.** We picked the GOA `PresentationIdentity` -+ property as the keyring username. On some GOA providers this is the -+ e-mail, on others it may be a display name. Should we instead use -+ the GOA `Identity` (UUID-shaped) field for stability across renames, -+ even if it makes the keyring entries less human-readable? This -+ choice affects how migrations would work later. -+ -+2. **Logging of GOA path at `info!`.** The new code logs the full -+ GOA path (`/org/gnome/OnlineAccounts/Accounts/1234`) at `info!` -+ level. It is not a credential but it does correlate to a specific -+ account on the user's machine. Acceptable, or downgrade to `debug!`? -+ -+3. **D-Bus peer-credentials restriction.** The current contract lets -+ any local process under the user call the `Auth` interface. Should -+ v0.1.0-alpha already restrict callers to the lnxdrive UI binaries -+ (Flatpak app ID match), or is that a v0.2 hardening? -+ -+## Approval -+ -+This ETH is `draft`. Approval workflow: -+ -+1. The reviewer reads the AILOG-2026-05-29-002 implementation alongside -+ this ETH. -+2. The reviewer either approves (set `status: approved`, fill -+ `reviewed_by`, `reviewed_at`, `review_outcome`, `approved_by`, -+ `approved_date`) or requests revisions. -+3. The corresponding GitHub PR (closes issue #5) cannot be merged -+ without an approved ETH per the project's `AGENT-RULES.md`. -diff --git a/.straymark/charters/01-road-to-v0-1-0-alpha-1.md b/.straymark/charters/01-road-to-v0-1-0-alpha-1.md -index 233c4da..d438eeb 100644 ---- a/.straymark/charters/01-road-to-v0-1-0-alpha-1.md -+++ b/.straymark/charters/01-road-to-v0-1-0-alpha-1.md -@@ -1,6 +1,7 @@ - --- - charter_id: CHARTER-01-road-to-v0-1-0-alpha-1 --status: declared -+status: in-progress -+started_at: 2026-05-29 - effort_estimate: L - trigger: "MVP audit on 2026-05-28 found engine ~70% / GNOME UI ~45% ready, four P0 risks unmitigated, zero release artifacts.

This is the **third ++ occurrence (N=3)** of the "declared but not wired" pattern reported upstream to ++ StrayMark (#205), and the first that is a *regression* of a shipped Fase-1 ++ mitigation. Fix: define the `goa` feature (default on); add the ++ `complete_auth_via_goa` proxy and drop `complete_auth_with_tokens`; hand the ++ GOA account object-path to the daemon (tokens never client-side). This also ++ surfaced and fixed a latent type error in `goa_sso` that had **never compiled** ++ (the feature was always off) — concrete evidence the GOA path was dead code. ++ The manual browser auth path (`start_auth` + `AuthStateChanged`) was unaffected. ++- **H2 (Medium) — daemon state not consumed.** Added the missing Sync/Status ++ properties+signals and `Settings.config_changed` to the proxies, and wired a ++ real consumer (AccountPage refreshes quota on `QuotaChanged`). ++- **H3 (Medium) — silent errors.** `folder_tree`, `sync_page`, and the onboarding ++ pages now surface load/save failures in the UI (inline error, error group, ++ toast/banner) instead of stderr; `folder_tree` distinguishes a parse error from ++ an empty tree. ++- **H4 (Medium) — folder_tree load race.** Merged the two independent load tasks ++ into one ordered task (selections first, then populate) so selections can no ++ longer apply to an empty tree. ++- **H5 (Low) — lint debt.** `cargo check` warnings cleared (unused imports, ++ deprecated `ActionRow::icon_name` → `add_prefix`); the audit also surfaced 145 ++ pre-existing `needless_borrow` clippy lints across the panel (the panel had ++ never passed clippy `-D warnings`), auto-fixed in this pass. ++- **G1 (gap) — "System" settings group.** Deferred to a v0.2 Charter ++ ([[AIDEC-2026-05-31-001]]): cache/dehydration need new daemon D-Bus API and are ++ post-alpha.

Executive summary ++ ++Fase 3 of Charter-01 is scoped as "implement the GTK4 preferences panel ++(currently a `println!("not yet implemented")` stub)". That stub is only the ++placeholder `lnxdrive-gnome/src/main.rs`; the **real panel already exists and is ++~95% built** under `lnxdrive-gnome/preferences/` — an `adw::Application` with a ++typed zbus client, an onboarding wizard, and four pages (Account, Sync, ++Conflicts, Advanced). It **compiles** (`cargo check` clean, 12 warnings) and, ++unlike the FUSE crate audited in Fase 2, it **does not have a fatal runtime trap** ++(async is correctly `async-io` + glib `spawn_local`, no stray `block_on`/ ++`tokio::spawn`; GSettings schema id/keys, app-id, and build wiring are ++consistent). ++ ++The audit was run because "compiles" is not "works" — the panel had never been ++exercised against a real daemon, and the zbus proxy contract is validated at ++**runtime**, not compile time. Three Explore agents (D-Bus contract / UI logic / ++async+build) produced findings that the calibrator reconciled and verified ++against source, rejecting four agent over-classifications. ++ ++**The one serious finding is a cross-component governance drift (H1):** Fase 1 ++(RISK-002) removed `Auth.CompleteAuthWithTokens` from the daemon and replaced it ++with `Auth.CompleteAuthViaGOA` to keep OAuth tokens off the D-Bus surface, but ++the **panel was never updated** — it still declares/calls `complete_auth_with_tokens` ++(now nonexistent), and that GOA code is behind `#[cfg(feature = "goa")]` while ++`Cargo.toml` defines **no `goa` feature**, so GOA SSO is compiled out entirely. ++This is the **third occurrence (N=3)** of the "declared but not wired" pattern ++already reported upstream to StrayMark (#205) — and the first one that is a ++*regression* of a shipped Fase-1 mitigation rather than an original gap. ++ ++Mitigating fact: the **manual browser auth path works** (`start_auth()` + ++`AuthStateChanged` signal, both present on the daemon — `auth_page.rs:238-295`), ++so the panel can still authenticate; only the GOA "use your existing Microsoft ++account" path (FR-019–023) is broken. Hence H1 is **High, not Critical**. ++ ++**Overall verdict: FUNCTIONAL_WITH_DRIFT.** The panel runs and mostly works; the ++material work is fixing the RISK-002 drift, three medium robustness items, lint ++cleanup, and the absent "System" group. ++ ++## 2. Scope ++ ++Audited: every Rust source under `lnxdrive-gnome/preferences/src/`, the zbus ++client contract against the daemon's interfaces in ++`lnxdrive-engine/crates/lnxdrive-ipc/src/service.rs`, plus `Cargo.toml`, ++`meson.build`, the GSettings schema, and the desktop/metainfo files. Not run: ++live execution against a mounted daemon (no authenticated account available in ++this environment) — deferred to manual verification. ++ ++## 3. Findings (calibrated) ++ ++### H1 — RISK-002 drift: GOA auth broken & compiled out — **HIGH** ++ ++- **Client** declares and calls `complete_auth_with_tokens(access_token, ++ refresh_token, expires_at_unix)` — `dbus_client.rs:88,235-243` and ++ `onboarding/auth_page.rs:362`. ++- **Daemon** removed that method in Fase 1; only `complete_auth(code, state)` ++ (`service.rs:873`) and `complete_auth_via_goa(goa_account_path)` ++ (`service.rs:917`) exist. `service.rs:902` states it "replaces the historical ++ `CompleteAuthWithTokens`"; the tests at `service.rs:2004` confirm it was ++ deleted. ++- The GOA UI is gated on `#[cfg(feature = "goa")]` (`auth_page.rs:20,35,143,338`) ++ but `preferences/Cargo.toml` defines **no `[features]`** → the gate is always ++ false → GOA SSO is compiled out (also the source of the `unexpected cfg value ++ 'goa'` warnings). ++- **Impact:** GOA SSO (FR-019–023) is non-functional and, if re-enabled as-is, ++ would call a method the daemon no longer exposes (`UnknownMethod` at runtime). ++ Manual browser auth is unaffected. ++- **Remediation:** (a) add `[features] goa = []` (decide default on/off) to ++ `Cargo.toml`; (b) add a `complete_auth_via_goa(goa_account_path)` proxy method ++ to `dbus_client.rs` and drop/deprecate `complete_auth_with_tokens`; ++ (c) rewrite `auth_page.rs::on_goa_sign_in_clicked` to pass the GOA account ++ object path to `complete_auth_via_goa` instead of fetching tokens client-side. ++ ++### H2 — Daemon state not consumed (no live status) — **MEDIUM** ++ ++- The client proxies omit several daemon-exposed properties/signals: `Sync` ++ `sync_status`/`last_sync_time`/`pending_changes` + `sync_started`/ ++ `sync_completed`/`sync_progress` (`service.rs:652-705`); `Status` ++ `connection_status`/`dbus_health` + `quota_changed`/`connection_changed` ++ (`service.rs:762-790`); `Settings.config_changed` (`service.rs:1066`). ++- **Impact:** the panel shows no live sync/connection status and does not refresh ++ on external changes. Functional gap, not a crash. ++- **Remediation:** add the missing properties/signals to the proxies and wire a ++ minimal set (sync status + quota refresh) into the relevant pages. ++ ++### H3 — Silent error handling — **MEDIUM** ++ ++- D-Bus call failures go to `eprintln!`/stderr, not the UI (e.g. ++ `sync_page.rs:200`, `account_page.rs`), so a dead daemon leaves the panel ++ showing default values as if loaded. ++- JSON parsing uses `unwrap_or_default()` (`folder_tree.rs:416`), so a malformed ++ `GetRemoteFolderTree` response renders an **empty tree indistinguishable from ++ "no folders"**. ++- **Impact:** silent degradation; user operates on stale/empty UI believing it ++ loaded. ++- **Remediation:** surface load/save failures via an `adw::Toast`/banner; ++ distinguish parse-error from empty in `folder_tree`. ++ ++### H4 — `folder_tree` load race — **MEDIUM** ++ ++- `FolderTree::new` fires `load_remote_tree()` and `load_selected_folders()` as ++ two independent `spawn_local` tasks (`folder_tree.rs:205-206`); `apply_selections` ++ can run before the tree is populated, dropping the selection highlight. A ++ related issue: `apply_selections` only walks root-level nodes, so lazily-loaded ++ children are not marked. ++- **Impact:** selective-sync selections may not display correctly. ++- **Remediation:** chain selections after the tree populates (await both, or ++ apply selections in the populate continuation); apply recursively as nodes ++ expand. ++ ++### H5 — Compiler warnings — **LOW** ++ ++- 12 warnings: unused `gtk4::prelude` imports (`sync_page.rs:11`, ++ `onboarding/mod.rs:17`, `app.rs:12`), `unexpected cfg value 'goa'` (resolved by ++ H1's feature definition), deprecated `ActionRowBuilder::icon_name` ++ (`confirm_page.rs:90,96`). ++- **Remediation:** remove unused imports; migrate the deprecated builder call; ++ the `cfg` warnings disappear once `goa` is a declared feature. ++ ++### G1 — "System" settings group absent — **GAP** ++ ++- The Charter names four groups (Account, Folders, Network, System). The panel ++ has Account, Sync (≈Folders), Advanced (≈Network), Conflicts — but **no ++ "System" group**, and the daemon exposes **no D-Bus API** for its candidate ++ settings (auto-start, cache, dehydration policy). ++- **Resolution — DEFERRED to v0.2** (see [[AIDEC-2026-05-31-001]]): the whole ++ "System" group is deferred to a future v0.2 Charter rather than implemented ++ partially in the alpha. Cache and dehydration controls need new daemon D-Bus ++ API; auto-start alone would be a one-toggle group mixing v0.1/v0.2 scope. Fase 3 ++ ships three wired groups (Account, Folders/Sync, Network/Advanced) + Conflicts; ++ the "System" group is out of alpha scope by that decision. ++ ++## 4. Rejected (agent over-classifications) ++ ++The calibrator verified and **rejected** these as not-a-bug for this codebase: ++ ++- **`.expect()` cascade in GTK factories** (`folder_tree.rs:227,260-318`) — flagged ++ CRITICAL by the UI agent, but these are idiomatic gtk4-rs factory closures where ++ the item type is guaranteed by construction (`TreeListModel`/`ListItem` always ++ yield the registered type). The async+build agent correctly rated them low. ++ **Rejected as CRITICAL; at most a stylistic LOW.** ++- **`Files` interface missing from client** — the panel is the *preferences* UI; ++ pin/unpin/file-status is Nautilus' concern, not this binary's. **Not applicable.** ++- **`conflict_list.rs:296` `STRATEGY_VALUES[i]` index** — the two arrays are ++ fixed-size consts of equal length; no runtime risk exists today. **LOW, not ++ CRITICAL.** ++- **async-runtime deadlock (FUSE-style)** — verified absent: zbus uses `async-io` ++ (not tokio), all D-Bus calls run via `glib spawn_local`, no `block_on`. **No bug.** ++ ++## 5.

This is the recursive half of H4 that the earlier fix left open. Make `selected_folders` the single source of truth: each checkbox toggle mutates it by path, and `create_model` reads it back when building child rows (a child is checked if explicitly selected or its parent is).

Complete the metainfo XML with description, releases section, and screenshot URLs. 6. **Release infrastructure & public assets** — `.github/workflows/release.yml` (tag → bundle → GitHub Release with SHA256SUMS); `SECURITY.md`; `CHANGELOG.md`; 6 UI screenshots in `docs/screenshots/`; version `0.1.0-alpha.1` consistent across every `Cargo.toml`, Flatpak manifest, and metainfo XML; README install section + competitive comparison vs `jstaf/onedriver` and `abraunegg/onedrive`. 7. **Tag, release, announce** — signed tag `v0.1.0-alpha.1`, GitHub Pre-release with Flatpak bundle, posts on r/linux, r/gnome, r/onedrive, and StrangeDaysTech Mastodon. diff --git a/lnxdrive-gnome/preferences/src/conflicts/conflict_list.rs b/lnxdrive-gnome/preferences/src/conflicts/conflict_list.rs index 684b9d3..b745c2b 100644 --- a/lnxdrive-gnome/preferences/src/conflicts/conflict_list.rs +++ b/lnxdrive-gnome/preferences/src/conflicts/conflict_list.rs @@ -209,20 +209,22 @@ impl ConflictListPage { None => return, }; - // Update page title with conflict count + // Keep the page/tab title fixed at "Conflicts" so the view-switcher tab + // doesn't truncate to "Conflicts …".
