toolBreakdown text, rather than relying on toolBreakdown’s independent
truncation. Preserve the existing count and breakdown content while ensuring the
emitted headline stays within the event budget, and extend the relevant summary
test with many unrecognised tool names to cover this case.
- Around line 89-118: Change activityLog deduplication to track claim counts
rather than booleans: update newActivityLog to initialize seen as
map[string]int, increment the bucket/value key in add, and decrement it in
withdraw. Remove the list entry and delete the key only when its count reaches
zero, preserving entries still referenced by other calls.
In `@internal/agentsessions/cache.go`:
- Around line 38-51: Update DiscoverAllCached so the discoveryMu lock is held
only while checking the cache and storing results, not while calling the slow
DiscoverAll operation. Unlock before discovery, allow concurrent misses
(including different workspaces) to proceed independently, then re-acquire the

In `@internal/agentsessions/paths.go`:
- Around line 97-117: Update globTranscripts in internal/agentsessions/paths.go
(lines 97-117) to reject matches with symlinked parent components and enforce
containment at open time using a rooted or handle-relative no-follow API,
including platform reparse-point protections; final-component Lstat alone is
insufficient. In internal/agentsessions/paths_test.go (lines 78-147), add
coverage where sessions/<slug> symlinks to a directory outside the store and
assert no transcript beneath it is returned.
- Around line 48-60: Update claudeCodeRoot and codexRoot so configured
CLAUDE_CONFIG_DIR or CODEX_HOME values are used only when absolute; treat
relative values like unset configuration and fall back to env.underHome with the
existing default subpaths.

- Around line 230-236: Replace the lexical filepath.Clean comparison in the
sessions import workspace check with the shared sessionMatchesWorkspace

appropriate shared package, update both callers to use it, and preserve the

directory cannot be determined.
- Around line 1-14: Add regression tests for the sessions discover and import
command flows, covering agent filtering, JSON output, failure exit codes, and

In `@internal/tui/session.go`:
- Around line 434-444: Update newSessionPicker to retain each session’s raw
update time on pickerItem, including items from both local assembly and
foreignSessionItems, then sort the merged items by recency before building the
picker. Add or reuse sortPickerItemsByRecency so sorting uses time.Time rather
than the formatted Label, while preserving per-agent item behavior.
- Around line 515-518: Guard session.UpdatedAt.IsZero() before formatting it, so
zero timestamps do not reach sessionWhen or sessionPickerLabel and produce a
year-1 date. Update the surrounding label logic in the session row path,
preferably by reusing or adding a typed time.Time variant of sessionWhen to
avoid converting the timestamp through RFC3339 text while preserving existing
behavior for populated timestamps.
- Around line 473-479: Move the synchronous agentsessions.Import call out of the
Bubble Tea Update path into a tea.Cmd that performs the import asynchronously
and returns a result message containing the session or error, then handle that

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A failed call can withdraw a value another call recorded successfully.
add deduplicates by bucket + value, so two calls that touch the same path produce one entry. withdraw removes that single entry unconditionally. If call t1 reads parser.go and succeeds, and call t2 reads parser.go and fails, the successful read disappears from "Files read". The summary then understates the prior work, which is the failure mode this file exists to prevent.
Count the claims per key and withdraw only when the count reaches zero.

Discovery runs while the global lock is held.
DiscoverAll reads four transcript stores and costs 50-300ms per the comment at Lines 10-13. That call happens at Line 48 with discoveryMu held. Every other caller of DiscoverAllCached blocks for the full duration, including callers for a different workspace that already have a valid memo. The comment states the goal is to stop the TUI hitching; a global lock around the slow path reintroduces the hitch on a concurrent open.
Release the lock while discovering, then re-acquire it to store the entry. Accept that two concurrent misses may both discover; that is cheaper than serializing every caller.

Gate the live-corpus test behind an explicit opt-in.
This test reads the developer's real ~/.codex store during a normal go test ./.... Two consequences follow. First, the result depends on private local data, so the same commit passes on one machine and fails on another; the t.Error calls at Lines 183-188 report a defect that no change in this PR caused. Second, the test opens the contributor's real transcripts, and t.Logf reports counts derived from them.
Require an opt-in environment variable, so the default suite stays hermetic.
The coding guidelines state: "path-sensitive logic must include a non-Linux case or a hermetic equivalent exercising the same normalization."

Reject a relative redirect value instead of probing the working directory.
env.underHome returns "" when home is unknown, so discovery never probes a relative path. The redirect branches do not apply the same rule. If CLAUDE_CONFIG_DIR=.config/claude is set, claudeCodeRoot returns .config/claude/projects and discovery reads relative to the process working directory. Require an absolute path in both branches.

The session picker resolves its agent environment at the leaf, which makes TUI tests host-dependent and blocks the missing dedup test. newSessionPicker → foreignSessionItems calls agentsessions.DiscoverAllCached(agentsessions.OSEnv(), m.cwd), and OSEnv reads the real os.UserHomeDir. One root cause produces both problems below: existing picker tests observe whatever transcripts the host happens to have, and no test can supply a controlled discovery result. Thread an agentsessions.Env through the model so both are fixable.

Move foreign-session import off the Bubble Tea Update loop.
agentsessions.Import synchronously reads the transcript to EOF, translates all events, creates the session, and appends the events. ReadOptions{} sets no MaxEvents cap. A large transcript can therefore block rendering and input handling, including Ctrl+C, until the import completes.
Return a tea.Cmd that performs the import and sends a result message. Consider an explicit MaxEvents cap if full imports are not required.

Guard the zero UpdatedAt before formatting it.
session.UpdatedAt.Format(time.RFC3339) on a zero time.Time yields "0001-01-01T00:00:00Z". sessionWhen then parses a valid timestamp and returns a stamp for the year 1, which sessionPickerLabel prints. The CLI path guards this case explicitly — formatDiscoveredTime returns "" for a zero time.
ForeignSession.UpdatedAt falls back to the file modification time, so it is normally populated. An adapter that cannot stat the file leaves it zero, and that row then renders a January year-1 date.
The round trip through a string is also avoidable if sessionWhen gains a time.Time variant, since the value here is already typed.
🐛 Minimal fix
label := displayValue(session.Title, "untitled")
- if when := sessionWhen(session.UpdatedAt.Format(time.RFC3339), now); when != "" {
- label = sessionPickerLabel(when, label)

Reviewed as a draft, so this is findings rather than a verdict. The design question you actually asked about is above my pay grade and needs @kevincodex1; what follows is whether the code does what it says.
The credential-safety work is the strongest part and it mostly holds. I checked the claims rather than taking them: the extension pin is case-insensitive, globTranscripts rejects symlinks because IsRegular() is false for them, and I confirmed by probe that a junction is rejected too. Two adversarial passes tried to turn the reparse-point gap into an escape and could not: creating a link under ~/.codex/sessions already requires write access to ~/.codex/sessions, and writing a transcript there directly reaches the same outcome with no link at all. The .jsonl pin plus the rollout-* pin plus Discover gating Import close the residual.
Two blocking, though.
The activity summary is emitted as EventCompaction, whose payload contract it does not satisfy. RehydrateEvents (replay.go:240) scans backwards for the last EventCompaction and restructures the transcript around it. A real CompactionPayload carries PreserveLast, CompactableEvents, PreservedEvents and CompactedThroughSequence — the bookkeeping saying which events the summary replaces. noteEvent writes {"summary": ...} and nothing else, so every one of those is zero, and rehydration reorders the imported transcript around a boundary that describes nothing. It decodes cleanly because the only validated field is Summary. Verified end to end through Import → ReadRehydratedEvents → PrepareExec. You picked the type because promptContextEvents already passes it; the same type has a second contract on the replay side.
Imported text carries control bytes into the terminal. The redaction chokepoint scrubs secrets, not control characters. Probed directly: "innocent title\x1b[2J\x1b[1;1H FORGED ROW \x00 tail" comes back byte-identical, ESC and NUL intact, and that string becomes a picker row and a transcript line. We have shipped this exact class twice in a fortnight: #835, where an MCP failure reason forged a row, and #876, where a copied NUL panicked the whole TUI. An imported title is strictly more attacker-influenced than either. sanitizeCardText already exists.
Two worth fixing before it leaves draft.
TestTheRealCodexCorpusStillParses and TestTheRealCorpusStillParses discover against the real ~/.codex and ~/.claude of whoever runs go test, and assert on what they find. The first fails at your head on this machine (indexed 2 of 2 rollouts; 2 titled, 0 with a model) because these rollouts carry turn_context past the 64-line head budget, which no change to the adapter can fix. CI passes only because the runner has no store to find. That inverts the usual bargain: green on CI, red for contributors. Worth a fixture.
The activity summary collapses successful and failed calls into one bucket per path. A successful Write /p/config.yaml followed by a failed Edit of the same path withdraws the claim entirely, so the summary reports no files changed although the file was rewritten. The withdraw logic is right in principle; it is keyed too coarsely.
Smaller: the family-1 slug fast path skips globSessionDirs, so the picker can list a session Import then refuses; name, toolCallId and role skip redact() while content and arguments get it, so the chokepoint comment is not literally true; capEvents understates the drop by one, and the note is the only thing telling the reader the import is partial; a tool call with no matching result keeps its claim, so an interrupted write reports as a file changed.
Two things I checked and am NOT raising, so you do not chase them. The Title field skipping redaction is real but pre-existing: createSessionTitle on main writes a raw prompt into metadata.json for native sessions too, and zero sessions list redacts at display. Your translate.go redaction is above baseline, not below it. And the reparse-point discovery gap is a documentation inaccuracy rather than a boundary crossing, for the reason above.
The engineering standard here is high: mutation-testing the glob and the redaction, exercising against 302 real sessions, and documenting the two pre-existing main failures instead of claiming a clean run. The two blocking items are both "this type/string has a second contract elsewhere", which is the hardest class to see from inside the change.
|
One correction to the blocking item above, since the sentence ran together: a real The cheapest fix is probably a distinct event type rather than filling in the payload, since the import is not a compaction and pretending otherwise will keep colliding with replay, rewind and lineage. If |
|
Tested the latest head with real local session data. Discovery, CLI import, source tabs, and importing/resuming a selected session all work on the normal path. I found three blockers:
There is also a smaller UX concern: importing a 2,692-event session synchronously blocked the UI for about 0.86s on this machine. Please fix at least the first three before merge. |

There was a problem hiding this comment.
Re-reviewed at 8689da21, this time as a verdict rather than notes, since it is out of draft. Ran it on Windows.
Both of my August blockers are properly closed, and I checked rather than took the commit titles.
noteEvent is now EventMessage with a noteEventSummaryKey marker instead of EventCompaction, so it no longer lands on a type whose replay contract it could not satisfy. That was the harder of the two to see, and the fix is the right shape: a marker on a type that has no side effect, rather than a payload padded out to look like a compaction.
Structural fields are redacted now too. role, name and toolCallId all route through redact(), so the chokepoint comment is literally true where it previously was not.
The control-byte fix introduced a different bug, and it is the one I would block on.
func redact(value string) string {
return stripControl(redaction.RedactString(value, redaction.Options{}))
}Redaction runs FIRST and matches by shape. stripControl then deletes the control byte with no separator, so it rejoins. A secret split by one therefore survives redaction and is reassembled afterwards, which is exactly backwards from what the chokepoint promises.
Proven here against the real redact, every key shape and every splitter:
unsplit -> "token [REDACTED] end"
NUL -> "token sk-ant-api03-AAAAAAAAAAAAAAAAAAAAAAAA end"
ESC -> "token sk-ant-api03-AAAAAAAAAAAAAAAAAAAAAAAA end"
backspace -> "token sk-ant-api03-AAAAAAAAAAAAAAAAAAAAAAAA end"
C1 -> "token sk-ant-api03-AAAAAAAAAAAAAAAAAAAAAAAA end"
Same for ghp_ and AKIA. The unsplit value redacts correctly, which is what makes this easy to miss: the tests that exist all use unsplit values.
This matters more here than almost anywhere, because the input is a foreign transcript. That is untrusted by construction, and the whole feature is reading it.
The fix is the order, one line:
return redaction.RedactString(stripControl(value), redaction.Options{})I verified that closes it. Every splitter above then gives token [REDACTED] end.
Worth saying plainly that this is the same defect as #835, where an MCP failure reason was redacted before the terminal sanitizer rejoined the halves. Two packages, same ordering, both written to be careful about exactly this. It is a genuinely non-obvious trap, and the general rule is worth writing down somewhere: normalize first, match second, because any normalizer that removes bytes without leaving a gap is also a reassembler. A regression with a split value belongs next to the existing redaction tests.
Still open from August: the real-corpus test fails for anyone with a real store.
--- FAIL: TestTheRealCodexCorpusStillParses
codex_test.go:177: indexed 2 of 2 rollouts; 2 titled, 0 with a model
codex_test.go:187: no session got a model — turn_context is being discarded again
Same failure and same cause as in August: these rollouts carry turn_context past the 64-line head budget. It passes on CI only because the runner has no ~/.codex to discover. That is the wrong way round, green for the robot and red for the contributor, and it is the first thing a new reviewer hits. A fixture pinning the past-the-budget case would make it deterministic and would test the adapter rather than whatever happens to be on the reviewer's disk.
Also, the branch is one commit behind main (cabfeef against 2d2450e9). Worth rebasing so it is reviewed against the tree it will land on.
Everything else I raised as smaller in August has been addressed, and go build ./... and gofmt are clean here.
The standard in this change is high, and both of the hard structural problems I raised were fixed properly rather than papered over. The ordering bug only shows up if you go looking with a split value, so no criticism in it having survived. Happy to re-review quickly.
|
Pushed // before
return stripControl(redaction.RedactString(value, redaction.Options{}))
// after
return redaction.RedactString(stripControl(value), redaction.Options{})The regression covers three key shapes against five splitters (NUL, ESC, backspace, DEL, C1) and fails against the old order with the intact credential in the output. Two things about the test worth knowing, because both are traps I walked into writing it. The C1 literal was lost somewhere between my editor and the file, leaving an empty splitter, and There is also a newline case, so the fix cannot degrade into "strip everything and call it redaction". A newline survives stripping and therefore separates rather than rejoins, and it is legitimate transcript content. Two items from my review are still open, so this is not ready yet:
The rest of the change is in good shape, and both structural problems from August are properly closed. Shout when the corpus test is fixtured and I will re-run the whole thing here. |

Re-reviewed at 582fa47b. The ordering blocker is properly closed and I checked it rather than reading the commit title.
redact is RedactString(stripControl(value)) now, and redaction_order_test.go is load-bearing. I reverted the one line and ran it:
--- FAIL: TestASecretSplitByAControlByteIsStillRedacted/anthropic_key/NUL
a credential split by NUL was reassembled after redaction and reached the
output: "token sk-ant-api03-AAAAAAAAAAAAAAAAAAAAAAAA end"
Every splitter, every shape. That is a test that would have caught the bug, which is the part that usually goes missing. The comment you left on it carries the general rule forward too, which I would rather have than the fix alone.
One thing left, and it is the same one from August.
The real-corpus tests still fail for anyone with a real store, and there are two of them now
--- FAIL: TestTheRealCodexCorpusStillParses
indexed 2 of 2 rollouts; 2 titled, 0 with a model
no session got a model — turn_context is being discarded again
--- FAIL: TestTheRealCorpusStillParses
indexed 15 of 21 real transcripts (71%) — too many are being dropped
Both pass on CI only because the runner has no store to discover. Green for the robot, red for the contributor, and it is the first thing the next reviewer hits before they have read a line of the feature. TestTheRealCorpusStillParses is new since I last looked, so the pattern is spreading rather than being retired.
The fix I would take is a fixture pinning the past-the-budget turn_context case and whatever shape the 6 dropped transcripts have. That tests the adapter instead of testing whatever happens to be on the reviewer's disk, and it turns the 71% into a number that means something. A clean t.Skip when no store exists would at least stop it being a false red, but it would also stop it finding anything, so I would rather have the fixture.
This is the only thing standing between the branch and my approval. Ping me and I will turn it around quickly.
Two smaller things
The branch is 2 behind main, and those two commits are #890 and #903. #903 is the Go 1.26.6 bump, so a rebase clears the vulncheck red on this PR rather than you having to explain it.
Minor, Windows only: internal/agentsessions/testdata/codex-home/sessions/2026/08/01/rollout-2026-08-01T10-00-00-fixture0-0000-0000-0000-000000000001.jsonl is about 130 characters repo-relative. Checking the branch out under a deep parent path fails outright with Filename too long. It checks out fine from a short root, so this is a nit rather than a blocker, but Windows is a required platform and that is not much headroom. Shortening the fixture stem would cost nothing.
Three separate changes hit this in a fortnight, each written by someone being careful about exactly the thing that got them. A transform that removes bytes without leaving a gap is also a reassembler. Redaction that matches by shape, run before a sanitizer that strips control bytes, lets a credential split by a NUL or an ESC pass the patterns as two fragments and be rejoined on the way out: the MCP failure reason in #835, and the imported-transcript chokepoint in #878. The path form of the same mistake is comparing where a handle landed against a value produced by the same resolver the kernel just used, so a redirect agrees with itself: the ACL guard in #808, where junctions were caught only by an accident of Go's mode bits and directory symlinks were not caught at all. The unsplit value passing is what makes it survive review, so the note says the test needs a split case.

@Vasanthdev2004 — all three fixed at I reproduced your numbers exactlyI couldn't reproduce the failure by running the tests, because they pass here — 44 of 44 rollouts with 43 models, 360 of 367 transcripts. That is the bug. Both tests assert statistics over whatever store the machine has, which isn't a property of this package. So I built a store shaped like yours and ran the tests at Your output, verbatim. Against the same store this branch passes and explains itself: What the shapes areThe model. The drops. But there is a real defect behind the same verdict, and nothing distinguishes them in the output. The cwd-bearing record is subject to The two smaller ones
The live-store tests now report their counts instead of asserting them. They still fail hard on a non-empty store indexing nothing, and on an index entry missing a field the CLI prints — the parts that are about the code rather than about the disk.

Gate local-session corpus tests behind explicit opt-in and use fixed failure diagnostics.
These tests inspect contributors’ local session stores during a normal test run. A failure currently formats transcript-derived fields such as title, working directory, or path, which can expose local data in test output. Require explicit opt-in before reading the local store, and replace the full record dump with a fixed diagnostic that names only the missing invariant.

Source: Coding guidelines
Adds internal/agentsessions, which reads the sessions Claude Code, Codex,
Factory Droid and Pi leave on the local disk and translates them into Zero
session events.
Four agents, two parsers. Claude Code, Factory Droid and Pi independently
arrived at the same layout — one JSONL file per session under a directory
named after the working directory, with text/thinking/tool_use/tool_result
content blocks — so one family-1 parser serves all three. Codex differs
enough to need its own: date-partitioned directories and every record
wrapped in a "payload" object.
Three rules hold throughout, each enforced by a test rather than left to
care:
1. Read-only. Nothing here writes to, moves or locks another agent's
store.
2. Path-exact globs, never a directory walk. Every one of these agents
keeps live credentials in the same tree as its transcripts —
~/.codex/auth.json, ~/.grok/auth.json, ~/.factory/auth.v2.key, and
most pointedly ~/.pi/agent/auth.json, the direct sibling of
~/.pi/agent/sessions/. Discovery uses fixed-depth globs pinned to one
extension, rejects symlinks by Lstat, and resolves session ids by
comparing glob results rather than joining an id onto a root.
3. Imported text is untrusted input and passes through
internal/redaction at a single chokepoint before reaching the event
log.
Discovery is a bounded head read (64 lines / 2 MiB), never a full parse:
the corpus this was built against is 439 MB across 1,266 files with a
single 73 MB transcript in it. The byte budget is sized from measurement —
three real sessions open with a ~334 KB record, and a 256 KiB budget was
spent before reaching the record carrying cwd, dropping those sessions from
discovery with no error anywhere.
The slugged directory name is treated as a hint only. It is lossy —
"-Users-x-dev-zero" is what both /Users/x/dev/zero and /Users/x/dev-zero
produce — so it narrows the search and the cwd recorded inside the
transcript decides.
Also emits an activity summary as EventCompaction events, because
sessions.promptContextEvents passes messages but not tool events: without
this the model continuing the work sees none of the files read, commands
run or errors hit. Zero's own compaction cannot substitute, since
toolPayloadPreview allow-lists id/name/toolName/status and drops the
arguments and output this needs. Each summary event stays under the
digest's 500-character per-event budget, and a call whose result failed

The architecture is coherent and the existing credential-boundary work is strong, but two core import/display contracts remain broken:
-
[P1] Full import must not silently discard JSONL records over 64 KiB. Both translators call
streamLineswithdefaultHeadLimit.MaxLineBytes, the discovery-time 64 KiB per-line cap. An ordinary long user or assistant message is truncated into invalid JSON and skipped with no error or truncation event. I reproduced this on0db68bewith a ~65 KiB assistant message: translation returned only the preceding user event and gave no indication that content was omitted. Full import should preserve bounded content with an explicit truncation marker, or at minimum emit an event saying which record was not imported; silent loss makes the resumed conversation look complete when it is not. -
[P1] Sanitize and redact every foreign field at CLI/TUI display boundaries.
formatDiscoveredSessionsprints foreign IDs, titles, branches, and models directly. A synthetic foreign ID/title containing ANSI escapes and an API-key-shaped value reached terminal output unchanged. The TUI'ssanitizePickerLabelremoves controls but still exposes the secret, confirming the latest CodeRabbit title-redaction concern. Import confirmation/workspace notes contain similar raw foreign fields. Normalize controls first, then apply secret redaction everywhere foreign metadata is rendered; JSON output is already structurally escaped and redacted.
Nonblocking: sameDir still relies on EvalSymlinks plus string equality, which can miss Windows junction/case aliases, and the empty-local-history test should exercise newSessionPicker directly rather than only pickerFromParts.
All CI checks are green. Clean race suites pass for internal/agentsessions and the focused CLI/TUI paths, and a real synthetic-transcript CLI smoke test confirmed normal discovery/import behavior.
…elds are redacted wherever they are drawn Both P1s from @anandh8x on 0db68be, plus the two CodeRabbit comments that overlap them. ## P1: a full import silently deleted ordinary long messages Both translators passed the DISCOVERY per-line cap to streamLines. 64 KiB is the right budget for the index — it is paid once per file across the entire store — and the wrong one for an import, which is a deliberate one-off read of a single file the user named. A single assistant reply over 64 KiB was truncated into invalid JSON, skipped as unparsable, and Read returned no error. Reproduced on 0db68be with a 65 KiB reply: Read err=<nil>, events=2 [0] {"content":"short question","role":"user"} [1] {"content":"follow up after the big one","role":"user"} The reply is simply gone. That is worse than incomplete: the restored transcript reads as a question, no answer, then the user's follow-up, so the person resuming it and the model continuing it both see a conversation that looks whole. Same call in codex.go, same result. Imports now use importLineLimit (8 MiB) — still bounded, since a corrupt file must not exhaust memory. A record past even that is no longer dropped in silence: readBoundedLineTruncated reports that bytes were discarded, and the translators emit an EventError naming how many records could not be read. It is an error event rather than a message because it is a note about the transcript, not a turn anybody took, and a model continuing the session must not read it as one. ## P1: foreign metadata reached the terminal unsanitized and unredacted formatDiscoveredSessions printed the id, title, branch and model straight out of another product's file. The picker learned to strip control bytes in the last commit, but stripping is not redaction — and a title is very often the user's first prompt, which is exactly where a pasted key ends up. agentsessions.DisplayField does both, in one place, in the order redaction_order_test.go already pins for the transcript path: controls first, so a secret split by an escape byte is reassembled before the shape match runs, then redaction. Newlines go too, unlike the transcript helper, because a metadata field is drawn as one row. sanitizePickerLabel is removed rather than left beside it — one helper doing half the job next to one doing all of it is how the halves drift apart. ## The two nonblocking notes Both reviewers asked for the empty-history case to go through newSessionPicker itself rather than only the extracted pickerFromParts. They were right: pickerFromParts is the piece added while fixing that bug, so testing only it leaves the branch that was actually wrong uncovered at its entry point. NOT done, and not forgotten: sameDir still uses EvalSymlinks plus string equality, which can miss Windows junction and case aliases. That is a real gap and it wants a Windows box to verify rather than an assertion written blind on macOS, so I would rather leave it named than claim it. Four mutations, each caught by its own test: restoring the discovery cap on the import path drops the long reply; removing the marker makes the over-cap record vanish again; DisplayField without redaction leaks the key into the picker row; and redacting BEFORE stripping controls lets a NUL-split key through. go test -race ./internal/agentsessions/ ./internal/tui/: clean. Pre-existing here and unrelated: TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider exit 3 in this environment.

@Vasanthdev2004 — ready for another look at Your blocker is fixed: both corpus shapes are pinned by fixture now rather than measured off the reviewer's disk. I could not reproduce your failure by running the tests — they pass here — so I built a store shaped like yours and got your output verbatim on Since your review, @anandh8x found two P1s that are also fixed here — one of them serious: a full import was silently deleting any message over 64 KiB, so a restored conversation read as a question, no answer, then the follow-up. |

The real-corpus blocker is closed. The two tests are fixture-driven now instead of reading whatever store the reviewer happens to have, which is what I asked for, and they are real fixtures rather than a deletion or a skip. Thank you for taking the harder version of that.
One thing from the same commit, and it is the shape I keep running into rather than anything careless.
TestAWorkspaceInAnOverlongRecordIsStillFound does not exercise an overlong record. The fixture's cwd-bearing line is 1024 bytes and defaultHeadLimit.MaxLineBytes is 64 << 10, so it sits 64x under the boundary it is named for. It only starts reacting if the production constant is cut to 512, which no regression would ever do.
The name is also the opposite of what the code does. Feeding a cwd record in at increasing sizes against the real cap: 1 KiB indexes the session, 60 KiB indexes it, 70 KiB does not, 200 KiB does not. A workspace in a genuinely overlong record is not still found. The whole session disappears from the picker, and the test's own Fatal string concedes it by talking about a record that "fits the real per-line cap".
That matters more than one misnamed test because two comments added alongside it tell the next reviewer the case is handled: the header here, and family1_test.go:266 describing the known defect as a cwd past MaxLineBytes. Your own header even names the failure mode exactly, that a session with no small following record "would vanish, and would look like a legitimate stub". So the analysis is right and only the coverage claim is wrong.
Either is fine by me. Make the fixture actually exceed MaxLineBytes and assert what really happens, renaming it to match, or keep the current fixture and rename it to what it pins, with the comments corrected so nobody reads the gap as closed. I would rather have an honestly named gap than a test whose name says it is covered.
Nothing else from this round is blocking. The redaction ordering work and the control-byte handling both hold up.
…six review findings @Vasanthdev2004 on the test I wrote, and six from CodeRabbit. Two of the CodeRabbit ones are bugs I introduced in fea5a56. ## The test claimed coverage it did not have TestAWorkspaceInAnOverlongRecordIsStillFound used a 1 KiB record against a 64 KiB cap — 64x under the boundary it was named for, so it only reacted if the production constant was cut to 512, which no regression would do. And the name asserts the opposite of the behaviour. Measured against the real cap: 1 KiB -> indexed 60 KiB -> indexed 70 KiB -> NOT indexed 200 KiB -> NOT indexed A workspace in a genuinely overlong record is lost. Worse than the misnaming, two comments added beside it told the next reviewer the case was handled, and the header even described the failure mode correctly while the test denied it. Renamed to TestAWorkspaceOnlyInAnOverlongRecordIsLost, driven across all four sizes against defaultHeadLimit.MaxLineBytes rather than a hardcoded number, and asserting what actually happens on each side of the boundary. The comment at family1_test.go now says the two pinned shapes are pinned as different things: "no cwd anywhere" as correct behaviour, "cwd only past MaxLineBytes" as an OPEN defect whose loss is asserted. An honestly named gap beats a test whose name says it is covered. ## Two bugs from the previous commit TERMINATOR COUNTED AS CONTENT. dropped included the trailing newline, so a record whose content exactly filled the cap reported as truncated — and CRLF was one byte worse. The import path emitted "could not be read" for records it had read in full, which is a false alarm in the one signal that exists to be trusted. "\n" content=64 keep=64 -> truncated=true (want false) "\r\n" content=63 keep=64 -> truncated=true (want false) OMITTED-RECORDS WORDING. The marker said "the conversation below" while both translators append it after the events. ## Four more scanHead reported success on every non-EOF read error, so a session indexed off whatever bytes arrived before an I/O failure was indistinguishable from one indexed off a whole file. EOF is now the only clean stop. scanHead opened with os.Open. globTranscripts already refuses a symlink wearing a transcript extension, but that verdict describes the tree at glob time and anything can replace the entry before the open. openContained resolves through an os.Root on the store root, so containment holds at the moment of the read. stripControl and DisplayField now drop category Cf. unicode.IsControl correctly says a format character is not a control character, which is the problem: U+202E reorders everything after it, so "gnp.txt.exe" behind an override renders as an image file while every byte stays innocent. Four CLI output sites now pass through DisplayField — the discovery warning, the parse and import error text, and the imported session id. An error string is not automatically safe: these wrap paths and ids read out of another agent's store. ## On my own mutation discipline The first pass at verifying these fixes found three surviving mutations, because I had fixed three things without regression tests — the same shape of mistake being reviewed above. Tests added for all of them, and the four mutations now fail: counting the terminator breaks 3 boundary cases, swallowing non-EOF errors breaks the read-failure test, dropping Cf lets 10 format characters through, and opening directly reads a file from outside the store root. An earlier run of those mutations reported all-clean because a literal BOM in the new test made the package fail to compile. A mutation against a package that does not build is indistinguishable from a test that holds. go test -race ./internal/agentsessions/ ./internal/tui/: clean. Rebased, 0 behind. Pre-existing here and unrelated: TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider exit 3 in this environment.

@Vasanthdev2004 — you're right, and thank you for measuring it rather than just reading the name. Fixed at I reproduced your numbers exactly against the real cap: So the test was named for the opposite of what the code does, and the 1 KiB fixture sat 64x under the boundary it claimed to guard — it only reacted if the production constant was cut to 512, which no regression would do. I took the first of your two options: the fixture now drives all four sizes against The part that bothered me most is the one you identified: two comments told the next reviewer the case was handled, and my own header described the failure mode correctly while the test denied it. Something I should flag about my own processVerifying these fixes, my first mutation run reported all four clean. Two reasons, both mine:

Found while verifying the previous commit rather than in review, which is why it is worth naming: I closed the instance and left the class open. CodeRabbit's finding named scanHead, and scanHead is what I hardened. streamLines sits beside it with the same os.Open and the same untrusted path, and it is the path with more at stake — scanHead only builds a picker row, while streamLines reads a transcript's actual CONTENT and writes it into the user's own Zero session. A symlink swapped in between the glob and the open would have copied whatever it points at into their store. Both Read paths already had adapter.root in hand and were not passing it. Now threaded, so discovery and import resolve through the same os.Root on the store root. Mutation-checked: opening directly again lets the import read a file from outside the root and hands its lines to the caller. go test -race ./internal/agentsessions/: clean.

…ead of losing the session CodeRabbit's answer to the previous commit, and it is the better one: recover the metadata rather than documenting its absence. A record over MaxLineBytes arrives as a prefix, fails json.Unmarshal and is skipped whole. Discarding the BODY is the entire point of the cap — a giant tool result must not be held in memory to build a picker row. But the fields discovery needs sit at the FRONT of the object, before the content that made it oversized, and throwing them away with the body cost the whole session: with no cwd there was no workspace to bind to, so a transcript the user can see on disk vanished from the picker and looked exactly like a legitimate empty stub. topLevelStrings reads cwd, gitBranch and timestamp off the prefix with a json.Decoder token stream. A token stream rather than a regex, because a regex over truncated JSON cannot tell a top-level "cwd" from one nested in a message body or an escaped string that merely looks like a key. The decoder stops cleanly at the cut, so anything recovered was genuinely complete and genuinely top-level, and anything after it is simply absent. Applied ONLY to a truncated line. A genuinely malformed one is still skipped: a live-appended transcript's last line is routinely half-written, and mining fields out of it would invent a workspace from whatever bytes happened to land. TestAWorkspaceInAnOverlongRecordIsRecovered now requires discovery at all four sizes — 1 KiB, 60 KiB, 70 KiB, 200 KiB — with cwd and branch intact, where the previous version asserted the loss. ## A test that could not fail TestAHalfWrittenRecordIsNotMinedForMetadata first put the valid record BEFORE the torn one. session.Cwd was therefore already set, the "only fill what is empty" guard hid any difference, and the test passed against a mutation that mined every unparsable line. Reordered so the torn line comes first; it now fails against that mutation. Both mutations verified: removing the recovery loses the oversized session, and mining every unparsable line takes the torn line's cwd. go test -race ./internal/agentsessions/: clean.

Re-checked at 08aee3d5. Both of my findings are closed, and you went further than I asked on the second one.
The real-corpus tests no longer fail for anyone with a store. That was my original blocker, green for the robot and red for the contributor. They report the ratio as a diagnostic now instead of asserting a threshold nobody's disk can satisfy. On my machine, which has both a live ~/.claude and a live ~/.codex:
--- PASS: TestTheRealCodexCorpusStillParses
indexed 2 of 2 rollouts; 2 titled, 0 with a model
... TestARolloutWithALateTurnContextIndexesWithoutAModel pins that shape deterministically
--- PASS: TestTheRealCorpusStillParses
indexed 21 of 32 real transcripts (66%) in the live store
Pointing at the deterministic test that pins the same shape is the right way to keep the observation without the assertion.
The overlong-record gap is fixed, not renamed. I expected a rename and an honest comment; instead the behaviour changed. TestAWorkspaceInAnOverlongRecordIsRecovered now generates records at 1 KiB, 60 KiB, 70 KiB and 200 KiB against the 64 KiB cap, which spans the boundary rather than sitting 64x under it. I falsified it by dropping the truncated-line recovery:
--- FAIL: TestAWorkspaceInAnOverlongRecordIsRecovered
a 71811-byte record (cap 65536) yielded 0 sessions; the workspace was not recovered
So the session that used to vanish now survives, and the test would notice if it stopped.
Recovering only from a TRUNCATED line and not from a malformed one is the right distinction, and TestAHalfWrittenRecordIsNotMinedForMetadata is the test I would have asked for if you had not written it.
The comment on that one is worth calling out:
THE TORN LINE COMES FIRST, so its cwd would win if it were mined. With the valid record first, session.Cwd is already set and the "only fill what is empty" guard hides the difference — an earlier version of this test made exactly that mistake and passed against a mutation that mined every unparsable line.
That is you catching your own vacuous test and leaving the reason in the file so nobody reintroduces it. I have hit that exact shape twice today in my own work, so it is not a small thing to have caught it unprompted.
Nothing blocking from me.

filepath.Cleanstill compares two workspace paths lexically.
Cleanperforms lexical tidying only. It does not resolve symlinks and it does not fold case. Two results follow:
- On macOS,
os.Getwdcommonly returns/private/var/...while the recorded cwd holds/var/...for the same directory. The strings differ, so the warning fires for a session that ran in this directory.- On Windows, the comparison is case-sensitive against a case-insensitive filesystem.

I found issues that need to be addressed before this is ready.
Findings
P1: Render imported metadata through a display-safe redaction/control-stripping path
internal/cli/sessions_import.go:210-225, 247-248; internal/tui/session.go:502-505
ForeignSession metadata is supplied by the foreign JSONL, so these are untrusted display values. Import persists the title after stripControl, but that helper intentionally preserves newlines, and cwd is persisted without sanitization. The CLI then passes title and cwd through displayOrNone and includes the raw recorded value in its warning; the TUI formats Source.ID and Session.Cwd directly. This bypasses the existing agentsessions.DisplayField boundary used by discovery/picker output, which removes C0/C1/Cf controls and newlines before redacting. A crafted imported title, cwd, or source ID containing a newline or ESC sequence can forge terminal/TUI output, while credential-shaped metadata can be exposed. Route every human-visible successful-import field through the same display-boundary helper, including the TUI note and the CLI title, cwd, and warning. Keep the stored metadata and transcript semantics unchanged.
P2: Make a failed append recoverable for the created session
internal/agentsessions/registry.go:155-172
Create succeeds before AppendEvents; if the append fails, the method returns an error but leaves the created metadata, import tag, and any state written by creation intact. foreignSessionItems then suppresses the original foreign source solely because that tag is parsed from ListResumable, before it filters out the zero-event local session. A retry or picker therefore loses the foreign source even though the local session has no transcript. The root cause is a multi-step persistence span with no post-create failure state. Make the operation atomic from the user's perspective by staging and committing it together, or by rolling back exactly the newly created session on append failure. If rollback itself cannot complete, explicitly surface the partial session as recoverable rather than treating it as successful import provenance.
… a failed import from hiding its source P1, reported by @jatmn. ForeignSession metadata is another product's bytes and every reader draws it. Import stored the title through stripControl -- which deliberately keeps newlines, right for a transcript line and wrong for a label drawn as one picker row -- and stored the cwd with no sanitizing at all. Neither was redacted, so a title, usually the user's first prompt and exactly where a pasted key lands, stayed a live secret in the store for each consumer to leak independently. Two of them did: the CLI import summary and the TUI note. Both now route through DisplayField, and so does the store on the way in, which is the chokepoint the per-consumer calls were standing in for. The workspace warning prints the sanitized path while still comparing the recorded one. P2, reported by @jatmn. Import creates the local session and appends its transcript as two steps. An append that failed left a session carrying the import tag and no events -- and the tag alone was enough for the picker to treat the foreign source as already imported and stop offering it, while the loop that builds local rows drops that same session for having no events. Both rows vanished and the import could not be retried, because its source was no longer listed. The two filters now agree on what a real session is: a session with no transcript is not import provenance. Nothing in the store deletes a session and inventing that primitive to unwind an import would hand every caller a destructive operation, so the empty session stays on disk and the error names it. Raised by CodeRabbit: the activity headline applied its character budget to the tool breakdown alone, so a session full of unrecognised tool names assembled a ~510 character note on top of it and summarizePayload cut it mid-sentence -- the exact failure maxSummaryEventChars exists to prevent. The budget now applies to the assembled line. The other two CodeRabbit findings on this head were already closed here: readBoundedLine no longer exists unused (it became readBoundedLineTruncated with two callers, which is what the Linux and Windows checks failed on), and fileModTime takes root and stats the handle openContained returned, with TestFileModTimeRefusesASymlinkOutOfTheRoot covering the replaced-symlink case.

[P1] Sanitize the imported foreign model identifier before persisting it
internal/agentsessions/registry.go:169
The importer treats title and cwd as untrusted display data and sends both through DisplayField, but copies source.ModelID directly into CreateInput.ModelID. That value is read from the other agent’s transcript in the family-1 and Codex indexers, so a transcript can supply terminal control bytes, bidi format characters, or a credential-shaped value as its model identifier.This is not confined to the initial discovery view. Import persists the raw value in Zero’s session metadata; later, the resume summary interpolates session.ModelID into its recorded-model suffix (internal/tui/session.go:349-355), while the generic local-session formatter only performs secret redaction (internal/cli/sessions.go:541-577) and does not neutralize terminal control characters. As a result, importing a transcript with an ESC/C1/bidi model field can create a durable local session whose metadata alters terminal output whenever it is resumed or listed; a secret in that field also remains in the local store and reaches consumers that rely on display-time redaction.
Address the root cause at the foreign-data ingress boundary rather than patching only the currently observed renderers: apply the same normalize-controls-then-redact policy used for title and cwd before assigning the foreign model value to session metadata. Ensure the stored value is safe for every later local-session consumer, retain ordinary model labels, and add a regression that imports a control-byte and split-secret-bearing model value, verifies the stored metadata, and exercises both the resume-summary and local session-list paths.
Review guidance
This feature has a high review surface because it turns files produced by four external tools into durable Zero session state, then exposes that state through multiple independent paths: discovery output, picker rows, import messages, metadata, session lists, resume summaries, event logs, transcript rendering, and prompt construction. The hard part is not a single escape sequence; it is proving that every foreign-controlled field is classified consistently from read through persistence and every later use. Fixing individual output sites after they are found is likely to miss the next persistence or restore path.
For the remaining hardening pass, build one explicit field-and-sink inventory for each adapter: identify every foreign value (including filename-derived IDs, cwd, title, branch, model, role, tool name, tool-call ID, arguments, output, errors, and summary text), whether it is persisted, and each terminal/JSON/prompt consumer that can read it later. Assign each field one of two contracts: transcript body text may preserve allowed layout such as tabs/newlines but must normalize controls before secret redaction; single-line metadata must use the display-safe normalize-controls-then-redact form before persistence. Apply the contract at the shared constructors/store boundary, not only at individual views.
Then validate the complete lifecycle, not just import creation: foreign file -> discovery/index -> Import/Create -> metadata on disk -> sessions list and JSON -> picker and import note -> TUI resume -> rehydrated transcript and exec prompt. Include malicious test values that cover ESC, C1 controls, bidi/Cf characters, embedded NUL, tabs/newlines, and credentials split by removable controls. Assert both that dangerous bytes and secret material are absent and that legitimate visible content remains; exercise stored/reloaded records so a test cannot pass merely because it checked an in-memory value.
Finally, consolidate the safety policy into a small number of shared helpers and add focused tests for every persistence boundary. That makes future adapters and fields opt into the same contract by construction, reduces repeated review churn, and avoids broad changes to unrelated local-session behavior.

Summary
Zero can now read the sessions other coding agents leave on the local disk — Claude Code, Codex, Factory Droid and Pi — list them, and continue that work in Zero.
In the TUI,
/resumegains a tab strip (All · zero · claude-code · codex · factory · pi) and lists un-imported sessions directly — choosing one imports and resumes in a single step.Draft, and deliberately so. There is no parent issue yet. Opening this to make the design concrete before asking for one, because the neighbourhood is sensitive — see Scope below.
Scope: how this differs from #399
#399 (
internal/agentcli) was closed on a deliberate design line: Zero talks to model APIs directly, does not wrap other vendors' CLIs, and does not reuse another product's subscription login. That closure invited "a narrow, self-contained slice… with no subprocess harness and no borrowed-identity tokens".This is that slice:
claude/codexbinariesImport is strictly one-way: nothing is written to, moved in, or locked in another agent's store.
Why it is small
sessions.FormatExecPrompt— behind bothzero exec --resumeand the TUI's/resume— renders the event log to a text digest rather than rehydrating a provider-native conversation. So an importer never has to reconstructtool_use/tool_resultpairs into Anthropic- or OpenAI-shaped messages. It only has to emit ZeroEventrecords, after which resume, fork, rewind, compaction, lineage and the picker all work unchanged.Four agents cost two parsers: Claude Code, Factory Droid and Pi independently converged on the same layout, so one family-1 parser serves all three. Codex needs its own (date-partitioned, payload-wrapped).
Credential safety
Every one of the surveyed agents keeps live credentials in the same tree as its transcripts —
~/.codex/auth.json(OPENAI_API_KEY + OAuth),~/.gemini/oauth_creds.json,~/.claude/.credentials.json,~/.grok/auth.json,~/.factory/auth.v2.key, and~/.pi/agent/auth.json, which is the direct sibling of~/.pi/agent/sessions/.So discovery is fixed-depth globs pinned to one extension, never
filepath.WalkDir; symlinks are rejected byLstat(a link namedx.jsonlpointing atauth.jsonotherwise passes the extension check); and a session id is resolved by comparing glob results, never by joining the id onto a root, so../../authmatches nothing.Imported text is untrusted input and passes through
internal/redactionat a single chokepoint.Both properties are mutation-tested: swapping the glob for a walk, or gutting the redaction call, each fail a test.
Tool work reaching the model
sessions.promptContextEventspasses messages but notEventToolCall/EventToolResult. Without help, a 22-event import gave the continuing model 2 messages and ~1,155 characters — no knowledge that any file had been touched.Zero's own compaction cannot substitute:
toolPayloadPreviewallow-listsid/name/toolName/statusand dropsargumentsandoutput, so a summariser learns that a Read failed but never which file or why. Those values are still in hand at translation time.So the translator emits an activity summary as
EventCompaction— a type the filter already passes — one event per category, each under the digest's 500-character per-event budget.promptContextEventsis untouched; native resumes are unaffected.A call whose result failed withdraws its claim, so a Read of a path that does not exist is never reported as a file that was read.
Behaviour changes to existing code
internal/tui/model_test.go: the session-picker assertion moves fromMeta == ""to "Meta must not contain the session id, and must name the source agent". That check has always been about keeping the raw id out of the row; empty-string was a proxy for it.applyQuerygains a tab filter that is a no-op for every picker without a tab strip (covered by a test).Verification
make fmt-check,go vet ./...,go build ./...,git diff HEAD --check— cleango test ./...— all packages pass except two pre-existing failures onmain:TestRunDoctorFormatsRedactedProviderDiagnosticsandTestRunDoctorConnectivityProbesProvider. Both reproduce on a pristineorigin/mainworktree with no changes from this branch.go test -race ./internal/agentsessions/— cleangolangci-lint(unused,ineffassign,staticcheck) — no findings in the new codebridge-sessionstubs), 14/14 Codex rollouts. Import →--resumeverified end to end.applyQuery, removed failed-call withdrawal, oversized summary events, summaries emitted before the conversation — each fails its test.Not included
Cursor, Cline, Roo, Windsurf, Continue, Aider, Grok, opencode and Gemini. Cursor and the VS Code family store chats in undocumented
state.vscdbblobs with no stability guarantee, and none were installed on the machine this was built against — there is no fixture to test them against, so shipping them would be guesswork.Known limits
Resume continues the work, not the process: the conversation, tool activity, cwd, branch and last state in flight are recoverable; the other agent's in-memory context, prompt cache and half-executed tool call are not. The activity summary is an activity log, not comprehension — it says what was done, never why.
Every one of these formats is a private, undocumented implementation detail of another product and will drift. That recurring maintenance, not the initial build, is the real cost — hence one small adapter per agent, each independently skippable, each pinned to checked-in fixtures so a format change fails a test rather than a user's import.
