fix(earthdata): read the remembered token at launch (#1626) - #1707
Takes the first two choices proposed in the issue and leaves the identity check from #1461 as it is.
The token is read at launch. The desktop app's first frame calls earthaccessui::restore, off the frame. A command started after that read has finished captures the restored identity; one started while it waits can still be cancelled, with the message below. The command line and Python keep reading lazily: opting in reads nothing, and a command whose parameters name an Earthdata data host reads the token just before it binds its accounts, so its first request doesn't cancel it. Three cases still get the message below: a script, model or plugin that finds its addresses as it runs, a tool on a layer whose source is on a data host, and a plan where an earlier step has already bound the accounts.
A restore that still lands mid-run says so.AccountIdentity::restored_since() tells that case from a real account change, and Node::current() reports "the Earthdata token remembered on this computer was read while this command ran; run it again". host.fetch also checks the node before it starts, so a plugin gets this message and not "request cancelled before it was sent".
Limits:
The other request paths (workflows, exports, Zarr and so on) still give the generic cancellation when a restore lands mid-run. Their still closures reduce the reason to a bool, and data can't see tiles. Passing the reason through would be a wider change, and the launch read makes the case rare.
host.fetch gets the better message when the restore happens before the fetch. A restore landing during a fetch stays generic for the same reason.
This adds a keychain read at launch for anyone with a credential store. On Linux I read zbus-secret-service-keyring-store: unlocking only runs when a locked item matches, so having no saved token doesn't prompt. I have not checked this on macOS or Windows.
Testing
With umask 022 on Linux, on this change based on 9a87877: cargo fmt --all --check, cargo clippy --workspace --all-targets -- -D warnings, cargo test --workspace (5218 passed, 0 failed, 22 ignored) and cargo xtask layers all pass. I then rebased onto a637b20 (GeoPackage: report omitted attribute tables #1665), which touches none of these files, and did not rerun them.
New tests: permission_policy_remembered_earthdata_token_read_mid_run (child process, so the process-wide token state stays isolated) and the_first_frame_reads_the_remembered_token. remembered_tokens gained restored_since cases: login, replacement and logout are not reported as restores.
Not run: the wasm32-unknown-unknown build (no clang on this machine), macOS or Windows, and a real Earthdata login or the BrasilData plugin from the issue. The behaviour is covered by the tests above only.
Remembered Earthdata credentials are restored when the app starts if a credential store is configured. The command line and Python interfaces read a remembered token when a command first needs it.
Downloads continue when a remembered token is restored before a command begins. If restoration occurs during a command, the download stops with a clear error.
Login, logout, or token replacement during a command still stops the download with an account-changed error.
Error messages do not expose token values.
Fetch operations now report an existing continuation error instead of replacing it with a fetch error.
A command's first use of a remembered token changed the account identity the
command had captured, so it cancelled its own requests. The app now reads the
token on its first frame, and a run that still reads it mid-way says so
instead of reporting a generic account change.
The native UI and opted-in commands now restore remembered Earthdata tokens. Earthdata identity state records token restoration. Command policy detects restoration during command execution, and fetch continuation checks propagate continuation errors.

Summary
Track remembered-token identity state crates/tiles/src/earthdata.rs
Earthdata identity records when a remembered token is restored and clears that state when the token is set, replaced, expires, or is forgotten. Tests cover these state changes.
Start token restoration in the native UI and opted-in commands crates/ui-egui/src/earthaccessui.rs, crates/ui-egui/src/lib.rs, crates/engine/src/lib.rs, crates/engine/src/prefs.rs, crates/engine/src/policy/plan.rs, crates/engine/src/tests/permission_policy.rs
Native UI logic invokes restoration. Saved-secret opt-in marks the session, and command binding restores the token for applicable operations before capturing runtime accounts. Tests cover UI restoration and command binding.
Detect restoration during command execution crates/engine/src/policy/scope.rs, crates/engine/src/policy/plan.rs, crates/engine/src/cmd/plugins.rs, crates/engine/src/tests/permission_policy.rs
Runtime account checks identify restoration during a command. The fetch path returns continuation errors when present. Tests cover restoration timing and account changes.
The previously reported token-state race is fixed, and no actionable issue remains that should block merging after normal checks.

Explanation
For #1626, the desktop app restores the remembered token at startup, and the account identity check still rejects a restore that occurs during a command. Node::current() reports the retry message, and tests cover restore timing and account changes. However, the PR description states that other request paths and a restore during host.fetch can still return generic cancellation. #1626 requires the cancellation message to explain that the remembered token was read during the command.
Resolution
Propagate the restore-specific cancellation reason through the request paths that still return generic cancellation, including a restore during host.fetch. Add tests for those cancellation cases. Keep the account identity check.

A rabbit checks the token’s trail, Then waits beside the fetch. If restoration shifts the state, The command will know it yet. A fresh run hops along its way.
CLI and Python still fail their first Earthdata download with a remembered token (medium-high confidence, inline at crates/engine/src/policy/plan.rs:350). These front ends read the token lazily, so the command's snapshot is taken with the token unread. The first data-host request calls restore() (tiles/src/earthdata.rs:399), RESTORED is set, and the next Node::current() returns "run it again". So every --use-saved-secrets run that downloads from Earthdata is cancelled after its first download. The PR body calls this a rare mid-run case, but for these front ends it is the normal path. I did not run this; the conclusion comes from reading downloads.rs:216, earthdata.rs:395-400 and the engine test.
Security
None found. The token is kept out of the RESTORED flag, and the new test asserts that the message does not contain the token.
Performance
None found. The launch read runs on its own thread and is guarded by the restoring flag.
Quality
Nit: RESTORED is a separate atomic beside the token mutex, so it can disagree with the token for a moment. set_token does not take the read lock that restore() holds, so the two stores are not atomic. The outcome is the same as before this PR, so I'd leave it for the release quality pass.
Nit: earthaccessui::restore runs on every frame and returns early after the first call. The comment on lib.rs:5002 could say that.
AGENTS.md
No violations found in the non-test changes: no unwrap/expect, the wasm branch is cfg'd, and the read is off the UI thread. The new tests cover both the mid-run and the ordinary cases.
Concern (medium confidence, inline at crates/ui-egui/src/lib.rs:5004): the launch read puts a keychain access on every launch for users with a remembered token. The PR says it is unverified on macOS and Windows. Commands started while the read waits can be cancelled with "run it again", even when they never touch Earthdata. The PR should state the macOS and Windows behaviour, or the read should be deferred to first use.
I left the other earlier concerns alone: there were no prior review threads on this PR.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Test leaks process-wide token state if an assertion fails.
The test calls earthdata::set_secret_store(None) only at its end. If an assertion fails first, the store and the token stay set. isolate_account_test appears to run the test in a child process, which limits the impact. Use a drop guard so the cleanup always runs. Also clear the token with earthdata::set_token(None).
923-999: Trivial · Maintainability & Code Quality · Low value
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Child-process test does not clean up on failure.
If an assertion fails in the child process, set_secret_store(None) and set_token(None) at Lines 997-998 do not run. The child exits, so the leak stays inside it. This is acceptable. The test also asserts !said.contains("synthetic"), which covers the credential-leak concern from the learning. The test never exercises the logout path, although the doc comment says "a login, logout or replacement". Add a logout() case, or remove "logout" from the comment.

… up front (opengeos#1626)
Their first download no longer cancels itself: opt_in reads the token before a
command binds its accounts. A read during host.fetch says why it cancelled, and
the restored flag now changes under the token's lock.
None confirmed. I checked the lock order across restore, forget_if_expired, set_token, login, logout and restored_since: read is taken before token_store everywhere, checked() takes no lock, and the RESTORED flag is written under the token lock. Confidence: medium-high.
The PR body overclaims that "commands started afterwards capture the restored identity". The desktop read runs on a background thread with no barrier, so a command started before that thread finishes binds an unread identity and is cancelled with "run it again" if the read lands. The earlier keychain-at-launch concern (lib.rs:5037) covers the same window. Confidence: medium.
Security
None found. The new messages carry no token value.
Performance
Nit: host.fetch now deep-clones the whole Continuation (JSON accounts, sources, tables) on every call. Negligible next to a network fetch. Confidence: low.
Quality
Inline comment posted on prefs.rs:87: opt_in now reads the keychain, which the docs say it never does. The CLI, Python and test comments are also stale. Confidence: high on the contradiction, medium on impact.
set_secret_store's doc ("It is read when first needed") is now inaccurate for the desktop and for CLI/Python. Nit.
The host.fetch branch in plugins.rs:492-503 has no test for the new mid-run message. The PR's tests cover only the token layer and the first-frame read. Confidence: medium.
AGENTS.md
No hard violation found. The opt_in contract issue above is the closest.
Prior reviews
Left alone: 1 earlier concern, the launch-time keychain read (lib.rs:5037), because the code still does it and the PR hasn't addressed it.
Already addressed by the diff, not re-raised: the CLI/Python first-download cancellation (plan.rs:350, fixed by the new restore() in opt_in) and the lock-ordering concern (earthdata.rs:223, outdated and fixed by holding the token lock while setting RESTORED).
I did not compile or run the tests; this review is by reading only.

Unverified finding

The test leaves the process-wide token set.
The test calls earthdata::set_secret_store(None) at the end. The restored token stays in token_store. isolate_account_test may run this in a child process, which hides the leak. Add earthdata::set_token(None).unwrap() at the end. This also covers the early-failure path if you use a drop guard.

…es a data host (opengeos#1626)
Opting in to saved secrets read the keychain at once, for every command
line run and Python session, and a keychain that made the read wait held
`Session(use_saved_secrets=True)`. That broke what opting in promises and
failed the Python binding test.
Opting in now only marks the session. A command whose parameters name an
Earthdata data host reads the token just before it binds its accounts, so
it isn't cancelled by its own first request. Commands that find their
addresses as they run (a script, a model, a plugin) still get the
"run it again" message when the read lands.
Medium confidence: The CLI/Python read of the remembered Earthdata token only fires when the command's own parameters name a data host (plan.rs:773). Three paths still cancel the first run with "run it again": plugin host.fetch (the URL is chosen in plugin code), tools on a layer whose source is already an Earthdata URL, and plans where an earlier reading node took the snapshot before a host-naming node (plan.rs:769). The next run works, so this is not silent, but it is only partly fixed. Posted inline.
Security
None found. The token is only sent by authorization() to data hosts; the new pre-read does not change that. names_earthdata_host walks iteratively, so hostile params cannot recurse.
Performance
None found. The parameter walk is bounded by charge, and https_host rejects non-https strings in constant time.
Quality
Low confidence:host.fetch (plugins.rs:497–502) has no test for the new restore message, though the PR body says plugins get it.
Low confidence:.map_err(|e| after.check().err().unwrap_or(e)) replaces a real fetch error (for example a 404) with the continuation error whenever the continuation has also failed by then. The reason is more accurate in the restore case but can hide the original error.
AGENTS.md
No violations found. There are no unwrap/expect calls in non-test code. The lock order (read → store → token_store) is consistent, so there is no deadlock. The desktop read runs on a background thread. Test isolation follows the existing isolate_account_test and child-process patterns.
Earlier concerns
Re-raised, with new content: the plan.rs:365 thread. The code changed, and the problem remains for the three paths above. Posted inline.
Left alone, already raised: the lib.rs:5037 thread on the launch-time keychain read (unanswered, code unchanged).
Left alone, resolved or outdated: the earthdata.rs:223 lock thread (addressed by moving the flag under the token lock), and the prefs.rs:87 thread (opt_in now only sets a flag and no longer reads the keychain).
I left 2 earlier concerns alone and re-raised 1.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Restore can run while a token is already held, and bind blocks on the keychain.
restore() can block on a system keychain prompt. bind calls it on the thread that plans the command. This is intended for the CLI and Python. It means a command that names a data host can wait for an unlock prompt before the plan is built. The restore() doc comment already notes that reading may ask the system to unlock its store. No code change is required. Consider a note in the CLI help that the first Earthdata command may prompt.

host.fetch now returns the reason when a read lands during the fetch (185d5a6). That path has no test of its own: it needs a plugin run against a data host that passes the public-address check, and the existing fetch tests serve a local port. The other request paths still give the generic cancellation, as the description says.
Left for the release quality pass: both tests run in their own child process, so nothing leaks past a failure. "logout" is removed from the doc comment.
