dfd3e2b360 docs(deny): correct the exemption-count attribution
Some checks failed
repo hygiene / hygiene (push) Has been cancelled
The Phase E commit message said deny-nigig-build.toml drops to 2
exemptions. It is 3, and the drop from 5 happened in Phase B, not E:
Phase B removed the two polkit-derived advisories by dropping the unused
robius-sms dependency from three manifests, and Phase E9 removed the
dependency itself so they are now unreachable rather than unlisted.

The three that remain (lopdf, ttf-parser, atomic-polyfill) are unrelated
to SMS -- they arrive via printpdf and the embedded stack. Comment in the
config now says so, so the next reader does not go looking for an SMS
link that is not there.

E1 -- the inbox was written to disk in plaintext.

  offline_store wrote every SMS body to
  app_data_dir/offline_store/sms_messages.json as pretty-printed JSON.
  SMS is the transport for OTPs, banking codes and M-Pesa
  confirmations, so that file was the user's complete authentication
  history sitting in app-private storage -- readable by anything running
  as the same UID, and included in backups.

  This repository already knew the answer. THREAT_MODEL.md T-I2 records
  "Raw SMS persisted to PSV file" as fixed in Phase 0, with raw_message
  omitted from save_to_disk() so it "lives in memory only". The SMS app
  then re-introduced the same defect at larger scale: the entire inbox
  rather than just M-Pesa messages, and with no retention limit until
  D6.

  OfflineSmsMessage.body is now #[serde(skip)]. Dropping the field
  rather than encrypting it is the deliberate choice: every consumer
  already reads the device provider FIRST and writes the cache second
  (nigig-sms fetch_from_device, and the mpesa and pay transaction
  pages), so the provider is the system of record and no body needs to
  survive a restart. Encryption would keep the plaintext reachable to
  anything holding the key. Not writing it removes the asset.

  Two consequences handled: sms_key() no longer hashes the body, since
  a reloaded row has an empty one and dedupe would otherwise never match
  its own cached entry and grow a duplicate per refresh; and the cached
  first paint shows a neutral placeholder rather than a blank preview
  for the instant before the provider read lands.

E9 -- the Linux backend's dependencies were pure cost.

  robius-sms declared polkit =0.17.0 and gio =0.17.0 for target_os
  = "linux". sys/linux.rs references neither: all twelve functions
  return Err(PermanentlyUnavailable). Those two crates dragged in glib
  and proc-macro-error and were the origin of RUSTSEC-2024-0370 and
  RUSTSEC-2024-0429 for every consumer of this crate.

  Deleting the block removes 340 lines from Cargo.lock. polkit, gio,
  glib and proc-macro-error no longer appear in the workspace at all,
  which also closes the LGPL-2.1 linkage question outright rather than
  routing around it as Phase B did for nigig-build alone.

E4 -- ROBIUS_SMS_BOOT_LIB was a code-injection vector.

  build.rs interpolated that environment variable straight into a Java
  string literal, which is then compiled, dexed and loaded at runtime
  with the app's full permissions. A value containing a quote closes the
  literal and injects arbitrary Java that runs on the device at boot.
  Build-time environment is not trusted input. Now validated against
  [A-Za-z0-9_]+ and the build fails loudly otherwise. Tested both ways:
  an exec payload is rejected, a legitimate name builds.

E5 -- undefined behaviour in the dex loader.

  new_direct_byte_buffer was handed RECEIVER_BYTECODE.as_ptr() as
  *mut u8 -- a &'static [u8] in .rodata cast to a mutable pointer, when
  the API is documented as taking writable memory and
  InMemoryDexClassLoader may write through it. Now copies into an owned
  allocation and leaks it, which is correct rather than lazy: the buffer
  backs a ClassLoader cached in a OnceLock for the process lifetime.

E6 -- two bindings for one native method.

  rustRestoreSchedules was both exported #[no_mangle] and registered
  dynamically via register_native_methods. Which one won was
  unspecified. Kept the dynamic one, because the class is loaded from an
  in-memory dex and is not on the JVM's search path, so symbol binding
  is not guaranteed to find it.

E8 -- no send rate limiting.

  Nothing capped send rate, and the bulk UI exists to blast a scraped
  directory. Android's practical throttle is ~30 messages per 30 minutes
  per app, past which sends are silently dropped -- so an unthrottled
  batch both overspends and fails opaquely. Adds SendRateLimiter, a pure
  token bucket taking an explicit clock so it is unit-testable without
  sleeping, wired into the bulk sender. A 200-recipient blast now stops
  at 30 and says why.

E10 -- robius-sms carried no license field, so cargo-deny needed a
  [[licenses.clarify]] override asserting one. Stated in the manifest;
  override removed.

E2 was already satisfied by D6 (retention capped at 5,000).

E7/E11 are documented rather than fixed, which is the honest status:
delivery confirmation needs real PendingIntents plumbed through
(A8 documents that Ok != delivered), and sender validation cannot be
solved client-side. Both are now rows in THREAT_MODEL.md instead of
findings in a markdown report -- along with T-I2b for E1 and T-I4 for
E3, which is NOT done: scheduled message bodies are still plaintext in
SharedPreferences.

CI: adds a gate asserting OfflineSmsMessage.body keeps #[serde(skip)].
Removing that attribute silently resumes writing plaintext and nothing
else would fail. Negative-tested.

deny-nigig-build.toml drops to 2 exemptions (from 5 before Phase B).

Tests: robius-sms 21 -> 25.
Verified: 12/12 CI jobs, clippy -D warnings clean on host and
aarch64-linux-android, cargo deny "advisories ok, bans ok, licenses ok,
sources ok", clippy ratchet holds at 49.

nigig-build declared robius-sms and robius-location and called neither:
zero references to robius_sms or robius_location anywhere under
nigig-build/src. That dead dependency pulled in

    robius-sms -> polkit -> gio -> glib -> glib-macros -> proc-macro-error

which is the ONLY reason deny-nigig-build.toml carried

    RUSTSEC-2024-0370  (proc-macro-error, unmaintained)
    RUSTSEC-2024-0429  (glib VariantStrIter unsoundness)

plus an unanswered LGPL-2.1 distribution question about linking polkit
into a shipped mobile binary -- all of it for code that never ran.

Removing the direct dependency alone was NOT enough, which is the part
worth recording. `cargo tree -p nigig-build -i polkit` showed three
paths, not one: the direct declaration, and two more through nigig-core
and nigig-uikit. Both of those also declare robius-sms and also never
use it. All three declarations had to go before polkit left the graph.

nigig-core keeps robius-location: unlike the others it genuinely uses it,
in src/location.rs.

Verified, not assumed:
  - before: cargo tree -p nigig-build -i polkit resolved, three paths
  - after:  polkit, gio and proc-macro-error no longer resolve at all
  - cargo deny check -> "advisories ok, bans ok, licenses ok, sources ok"
    with two fewer ignores (5 -> 3)
  - nigig-build, nigig-core, nigig-uikit and nigig-sms all still compile
  - Cargo.lock loses 5 lines

Also in this commit:

  - A CI gate so the declarations cannot come back. Deliberately scoped
    to robius-sms/robius-location on these three manifests rather than a
    blanket `cargo machete`: five other unused dependencies exist here
    (chrono, futures, postcard, rand, serde_json) and a gate that is red
    on its first run gets switched off. Negative-tested by re-adding the
    dependency and confirming the gate fails.

  - Three pages carried the same placeholder string telling the user
    they were looking at a "RobrixStackNavigationView destination ...
    just like SMS conversation screens". That is user-visible UI copy,
    not a comment. Replaced with text describing the page. The identical
    "This follows the SMS/Home pattern" comment in the same three files
    now says what the code does instead of naming another module.

Note the scope limit: 26 of the 29 crates in this workspace declare
robius-sms and never use it. This commit fixes the three that put
advisories on nigig-build. The rest are the same latent problem and
should be swept separately.

80c3f578dd ci(cad): gate nigig-build with cargo-deny (Phase 0.4)
Some checks failed
nigig-build (CAD) / supply-chain (push) Has been cancelled

nigig-build (CAD) / full-crate-check (push) Has been cancelled

Blocked since Phase 0 because cargo-deny resolves from the lockfile, and
unblocked once Cargo.lock was committed in 0.2. I predicted this would
surface a large backlog. It did: 5 advisories, 6 licence rejections, 126
git-source errors and 20 unlicensed crates.

The triage is the work here, not the config.

ONE ACTUAL VULNERABILITY. RUSTSEC-2026-0187: unbounded recursion parsing
nested PDF objects in lopdf 0.31, reached via printpdf 0.7. A ~21 KB
crafted file aborts the process with SIGABRT, and because it is a stack
overflow rather than a panic, catch_unwind cannot contain it.

Not exploitable here, and I checked rather than assumed. The advisory is
specifically about Document::load*, the parsing entry points. This crate
never parses a PDF -- arch_pdf.rs only writes them through printpdf's
drawing API, there is no lopdf import anywhere in the workspace, and
there is no PDF read path of any kind. There is also no fix in range:
printpdf 0.7 pins lopdf 0.31 and `cargo update -p lopdf` moves nothing.
Clearing it means printpdf 0.8+, a breaking change across arch_pdf.rs.

So it is ignored with the reasoning written down AND with the condition
that invalidates it: the moment anything in this crate reads a PDF -- an
import feature, a thumbnailer, a preview pane -- this becomes a live DoS
and the ignore must go. An ignore without its expiry condition is how
real vulnerabilities get inherited.

The other four advisories are unmaintained/unsound transitive crates
(proc-macro-error, ttf-parser, atomic-polyfill, glib VariantStrIter),
none with a safe upgrade, all arriving through the GUI/platform stack.
Listed individually rather than disabling the unmaintained class, so a
new one still fails.

Six licence rejections were permissive licences simply absent from the
allow list. MPL-2.0 (option-ext) is weak copyleft, so it is granted to
that one crate rather than added globally -- MPL reciprocity is per-file
and only bites if the crate is vendored and edited.

The 126 git-source errors and 20 unlicensed crates are artifacts, not
findings. Every git dependency is pinned to a full rev, which is stronger
than a version range and already enforced by its own CI step; the
unlicensed crates are first-party and vendored forks with no license
field. Both handled WITHOUT allow-ing the class: sources are governed by
the rev-pinning step, and the 20 crates are clarified by name, so a
genuinely new unlicensed dependency still fails. Blanket-disabling would
have hidden exactly the case worth catching.

Separate file from deny.toml on purpose. Merging them would mean
loosening the payment rules to fit a Makepad + Robius graph, and the
payment policy is the one worth keeping tight. Verified both pay crates
still pass unchanged.

Negative-tested in both directions: removing the lopdf ignore fails the
gate, and removing MIT from the allow list produces 79 rejections. A gate
that cannot fail is worse than no gate.

622 lib + 154 integration, 0 failed.
