From 2b384c34218ee8fbe556fd019891d6d5e852faae Mon Sep 17 00:00:00 2001 From: KRATOS Date: Sat, 8 Aug 2026 12:02:54 +0530 Subject: [PATCH 01/34] feat(agentsessions): read other coding agents' local session transcripts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 withdraws its claim so a Read of a nonexistent path is never reported as a file that was read.

The provenance tag records both the agent and the source session id, which is what lets a caller tell an already-imported session from one still only on the other agent's disk. An adapter that fails is reported as a warning and does not fail the command: these are undocumented formats belonging to other products, and one vendor shipping a new layout must not deny the user the other three. Nothing here reads another agent's credentials, launches its binary, or uses its subscription. The imported session runs on Zero's own provider with the user's own key.

All lists everything with the source agent on each row; Tab narrows to one agent and wraps back to All. Typing to search still works and the query survives a tab change, since switching agents is a narrowing rather than a reset. Tabs are built from what is present, so an agent never used gets no tab and a single-source store gets no strip at all — "All | zero" is chrome that says nothing. The picker also lists sessions from other agents that have NOT been imported yet; choosing one imports it and resumes in a single step. Without this the strip was honest but nearly empty: in a workspace with 137 discoverable Claude Code sessions it offered the one that had been imported by hand. `/resume :` accepts the same reference from the command line. Zero session ids cannot contain a colon (sessions.ValidSessionID), so the form is unambiguous. Discovery is memoised per workspace for ten seconds and invalidated on import. Opening the picker costs a bounded read of every transcript across four stores; paying that on each keypress made /resume hitch every time it was opened and dismissed. The tab filter is applied before the query ranks results, so an empty search box shows one agent's sessions rather than every agent's — the exact moment the strip has to be trusted. model_test.go's session-picker assertion moves from "Meta must be empty" 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, which consumed half the picker and truncated the title; empty-string was a proxy for it.

Control bytes reached the terminal. redact() scrubbed secrets but not control characters, and the title and structural fields (name, toolCallId, role) skipped it entirely, so an imported title or message carrying ESC or NUL forged a picker row or corrupted a transcript line — the #835/#876 class, on strictly more attacker-influenced input. redact() now composes a stripControl pass (C0 except tab/newline, DEL, C1), and every rendered string — including the title at the import chokepoint — routes through control-stripping. The activity summary was emitted as EventCompaction, whose payload it did not satisfy. RehydrateEvents restructures the transcript around the last EventCompaction; a summary with no CompactableEvents/CompactedThroughSequence is hoisted to the front of the transcript on resume. It is now an assistant EventMessage, which still passes promptContextEvents (the resume digest) but carries none of that replay-side contract. A payload marker keeps it distinguishable from a translated turn, so filters and the digest can tell a Zero-generated summary from the foreign transcript. Also: the import-tag comment now matches ImportTag's actual output. Tests: regression coverage for both fixes, mutation-checked (removing the control strip surfaces the surviving byte; the summary type is asserted not to be EventCompaction). Existing tests updated for the new summary shape via a shared NoteEventIsSummary marker rather than the old EventCompaction type check.

RedactString matches secrets by SHAPE, and stripControl deletes a control byte without leaving a gap, which makes it a reassembler as well as a sanitizer. Running it second meant a foreign transcript could split a credential with a NUL, an ESC, a backspace, a DEL or any C1 byte, sail past the shape patterns because neither half looks like a key, and then have the halves rejoined on the way out to a picker row or a transcript line. Every recognized shape leaked that way: sk-ant-, ghp_, AKIA. The unsplit value redacted correctly, which is why it survived review twice; every existing test used unsplit values. Swapping the order fixes it. The patterns now see the same text the reader will see, which is the only text worth matching against. This is the same defect as #835, where an MCP failure reason was redacted before the terminal sanitizer rejoined its halves. The general rule is worth stating where the next person will hit it: any normalizer that removes bytes without leaving a gap has to run BEFORE whatever matches on them. The regression covers three key shapes against five splitters and fails against the old order with the intact credential in the output. It also asserts the splitter is non-empty, because a lost literal would make every Contains check vacuously true, and keeps a newline case to pin that separators which survive stripping are left alone rather than swept up with the rest.

The comment said the halves "must NOT become the secret" and nothing checked it. The newline assertion alone passes just as well if the matcher spans the newline and redacts both halves as one, because the separator would survive inside a "[REDACTED]" that ate the text around it. Both halves are now named, and so is the absence of any redaction at all. The failure this guards against is over-redaction: a credential cannot contain a raw newline, so treating a newline-split pair as one destroys legitimate transcript content while protecting nothing. It is also what stops stripControl being widened to strip newlines, which would make the NUL case in the test above pass for the wrong reason. Measured, to pin the three-way distinction: newline -> "before sk-ant-api03-\nAAAA... after" not redacted, halves intact joined -> "before [REDACTED] after" NUL -> "before [REDACTED] after" stripped, so it rejoins Mutation-checked: removing the '\t'/'\n' exemption from stripControl fires all four assertions.

He is right, and the mechanism is worse than a threshold being too tight. Both tests assert STATISTICS over whatever store the machine running them happens to have, which is not a property of this package. The same code at 582fa47b reported "44 of 44 rollouts, 43 with a model" and "360 of 367 transcripts" here and "0 with a model" and "15 of 21 (71%)" for him. Green for the robot, red for the contributor, and the assertion never ran where a regression would actually land, because CI skips. Reproduced his exact numbers by constructing a store shaped like his and running the tests at 582fa47b against it: codex_test.go:184: no session got a real title codex_test.go:187: no session got a model - turn_context is being discarded again --- FAIL: TestTheRealCodexCorpusStillParses family1_test.go:253: indexed 15 of 21 real transcripts (71%) --- FAIL: TestTheRealCorpusStillParses Against the same store this branch passes and says why: no session in the live store carries a model: every rollout here has its turn_context outside the head budget. TestARolloutWithALateTurnContextIndexes- WithoutAModel pins that shape deterministically (2 rollouts) ## What the shapes actually are Enumerated against the real 44-rollout and 367-transcript stores here. MODEL. turn_context is the only record carrying one; session_meta has no "model" key at all. It lands at line 4-8 and byte offset 15KB-175KB here, comfortably inside the head budget, and outside it on his machine. The session is still listed, titled, addressable and importable - only the label is missing - and Discover walks the whole date-partitioned store on every picker open, so the bounded read is the right trade. The fixture pins the current behaviour rather than asserting recovery, and says in the comment that teaching the index to recover it should fail this test deliberately rather than drift. DROPS. cwd is only ever carried by user, attachment and system records; the preamble types never carry it. All 7 unindexed transcripts here are single bridge-session stubs with no cwd anywhere - legitimate, since a session with no workspace cannot be resumed into one. There is also a real defect behind the same "no cwd" verdict, and nothing distinguishes them in the output: the cwd-bearing record is subject to MaxLineBytes, and a truncated record fails to parse and is skipped whole. That is already happening to the opening user record in 30 of 367 transcripts here; they survive only because Claude Code writes a small attachment next that also carries cwd - 73 of the 360 indexed sessions (20%) take their cwd from an attachment for exactly this reason. One without that rescue would vanish and look like a stub. TestAWorkspaceInAnOverlongRecordIsStillFound pins it; shrinking MaxLineBytes below the record's length drops the session and fails the test. ## Also - Rebased onto main. His note said 2 behind (#890, #903); it was 14 by the time this was done. Clean, and the merged tree builds. - Longest testdata path 133 -> 108 chars for the Windows checkout limit, by shortening the two fixture roots and the rollout stem. The trailing uuid is kept because codexID reads the session id from it. - 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. Three mutations, each caught by the test written for it: removing the cwd guard indexes both unresumable stubs; shrinking MaxLineBytes drops the long-cwd session; raising MaxLines lets the head scan reach the late turn_context. Pre-existing here and unrelated: TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider exit 3 in this environment.

Aug 2026 11:38:34 +0530 Subject: [PATCH 09/34] fix(tui): the import path is reachable with no local history, and a foreign title cannot repaint the picker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All four raised by CodeRabbit on ad57dd3c. Two are real defects in this PR's own feature, not test issues. ## The feature was invisible to the user it exists for newSessionPicker gave up on an EMPTY local history: metas, err := m.sessionStore.ListResumable() if err != nil || len(metas) == 0 { return nil } Foreign sessions are discovered independently of the store, so the person with no Zero sessions at all — someone who just installed it and wants to carry on work another agent started — got nil before discovery ran. The import path was reachable only after they had already done by hand the thing it exists to save them. A failed read is still a reason to give up; an empty one is not. Emptiness is now decided after combining both sources, in pickerFromParts, split out so that decision is testable without a session store on disk. ## A foreign title reached the terminal unfiltered registry.go strips control bytes when a session is IMPORTED, and its comment names this picker row as the reason (#835/#876). But the picker lists a session BEFORE anything is imported, reading the title straight out of the other agent's transcript — so the vector that comment describes was the one path the stripping did not cover. An escape repaints the rows above, a carriage return hides the rest of the label, a NUL can truncate the row. sanitizePickerLabel drops control bytes and keeps the printable text: a title that is merely unusual must stay readable, because the row is how the user recognises their own work. ## The live-store test printed the developer's own sessions t.Errorf("incomplete index entry: %+v", session) That walks the REAL store, so a failure put the user's session titles, working directories and file paths into the test output and into any log or pasted report carrying it. It now names which fields are empty, which is the whole diagnostic — the missing value is by definition not the interesting part. NOT taken from the same comment: gating the live-store tests behind an explicit opt-in. @Vasanthdev2004 asked for the opposite in the review this branch is answering — a skip "would also stop it finding anything, so I would rather have the fixture" — and the tests now only report. The data leak was the substantive half and it is fixed. ## The symlink test asserted the weaker half of its property It checked only that Discover and Read AGREE, which passes in two opposite worlds: both correctly refusing a path reached through a symlink, and both happily following it out of the store. Containment is now asserted directly — "sneaky" must not be listed and must not be readable — and agreement is kept afterwards, since that is what the original fast path broke. Not taken, out of scope: three findings in internal/tui/model.go, which this branch does not touch (CodeRabbit marks them "outside diff"). They look real — particularly toolResultSessionPayload persisting displayPreview for a redacted result — and deserve their own issue rather than a drive-by in a draft. Mutations: restoring the len(metas) == 0 return makes the new-user test fail; removing sanitizePickerLabel lets all four control bytes through. Pre-existing here and unrelated: TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider exit 3 in this environment.

A single assistant reply over 64 KiB was truncated into invalid JSON, skipped as unparsable, and Read returned no error. Reproduced on 0db68bef with a 65 KiB reply: Read err=, 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.

Two of the CodeRabbit ones are bugs I introduced in fea5a565. ## 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.

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.

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.

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. --- internal/agentsessions/activity.go | 13 +- internal/agentsessions/activity_test.go | 41 +++++++ internal/agentsessions/codex.go | 2 +- internal/agentsessions/family1.go | 2 +- internal/agentsessions/family1_test.go | 35 ++++++ internal/agentsessions/jsonl.go | 27 +++-- internal/agentsessions/jsonl_test.go | 45 +++++++ internal/agentsessions/registry.go | 32 +++-- internal/agentsessions/registry_test.go | 94 +++++++++++++++ internal/agentsessions/translate.go | 20 +++- internal/cli/sessions_import.go | 37 ++++-- internal/cli/sessions_import_test.go | 145 +++++++++++++++++++++++ internal/tui/session.go | 57 +++++++-- internal/tui/session_import_note_test.go | 94 +++++++++++++++ internal/tui/session_picker_tabs_test.go | 35 ++++++ 15 files changed, 639 insertions(+), 40 deletions(-) create mode 100644 internal/agentsessions/registry_test.go create mode 100644 internal/cli/sessions_import_test.go create mode 100644 internal/tui/session_import_note_test.go diff --git a/internal/agentsessions/activity.go b/internal/agentsessions/activity.go index 2dcfe11be..88d40e395 100644 --- a/internal/agentsessions/activity.go +++ b/internal/agentsessions/activity.go @@ -280,7 +280,12 @@ func (log *activityLog) summaryEvents() []sessions.AppendEventInput { if extra := log.toolBreakdown(); extra != "" { headline += " " + extra } - events = append(events, noteEvent(headline)) + // THE BUDGET APPLIES TO THE ASSEMBLED LINE, NOT TO A PIECE OF IT.

Tool arguments are sanitized as decoded values, not as serialized bytes. A JSON-escaped path held no ESC byte and no key prefix while encoded, so the sanitizer passed it whole and the TUI's argHint decoded it on resume into a live escape and a complete PAT in the tool row. toolCallEvent, the one constructor both adapters use, now decodes, redacts every string leaf and re-encodes; free-form Codex scripts stay text. Redaction runs on both sides of control stripping. Stripping assembles a key split by a control byte (already covered) and also erases the word boundary an intact key needs when the control sits just before it, so "progress\rsk-ant-..." survived messageEvent. Both directions now hold at once. Foreign Windows paths are compared without resolver I/O. The TUI's sessionMatchesWorkspace ran EvalSymlinks before its Windows branch, so a transcript cwd of \\server\share\repo could dial the share from the Update loop while formatting the post-import note or filtering the picker. It now delegates to the lexical, case-insensitive policy discovery already uses. The reference-only boundary survives the resume digest. The boundary note was an ordinary message and the digest keeps the last 80, so any import of 80 or more turns lost it on the first resume while keeping every foreign turn. Every imported event now carries a marker and FormatExecPrompt regenerates the label from the retained window when the note itself is gone -- derived from the events that are present rather than from one event surviving truncation, compaction or a fork. The 80-event budget is unchanged. Pi is parsed with Pi's schema. It shares family 1's directory layout and not its message vocabulary (toolCall blocks with object arguments, a separate toolResult role with isError, an outer type of "message" on every entry), so routing it through the Claude parser dropped every call and result and titled every session "untitled". pi.go carries the vendor's parsing; bounded reading, event construction, redaction, the reasoning opt-in and the activity summary stay shared. A late picker result cannot switch a running session. Bare /resume checked m.pending at dispatch only; the asynchronous result installed the picker regardless and a selection then switched activeSession under a live run whose completion appended into the other conversation. Results are now bound to the request generation and originating session and refused while a run is active, and the selection route rechecks on its own before any mutation. Discovery stays asynchronous. The file that was verified is the file that is read. Read validated the selected path through one handle, translated through a second open and validated through a third; a writer that swapped the entry between those lookups had B's bytes accepted under A's provenance. One handle is now opened and proved against the discovery snapshot, read, and proved again on the same handle after the last byte. Rooted open, regular-file check and bounded extent are unchanged. Each fix carries a regression at the consumer where the property has to hold, and each was confirmed to fail with the fix reverted. --- internal/agentsessions/activity_test.go | 24 +- .../agentsessions/blocker_regression_test.go | 2 +- internal/agentsessions/codex.go | 13 +- internal/agentsessions/codex_test.go | 10 +- internal/agentsessions/export_test.go | 35 +++ internal/agentsessions/family1.go | 30 ++- internal/agentsessions/import_resume_test.go | 90 +++++++ internal/agentsessions/jsonl.go | 82 ++++-- internal/agentsessions/jsonl_test.go | 4 +- internal/agentsessions/paths.go | 35 ++- internal/agentsessions/paths_test.go | 38 +++ internal/agentsessions/pi.go | 246 ++++++++++++++++++ internal/agentsessions/pi_test.go | 153 +++++++++++ .../agentsessions/redaction_order_test.go | 40 +++ internal/agentsessions/registry_test.go | 130 +++++++++ internal/agentsessions/translate.go | 118 +++++++-- internal/agentsessions/translate_test.go | 123 +++++++-- internal/sessions/exec_session.go | 83 ++++++ internal/tui/model.go | 69 +++-- internal/tui/session.go | 77 ++++-- internal/tui/session_picker_tabs_test.go | 3 +- internal/tui/session_stale_picker_test.go | 194 ++++++++++++++ 22 files changed, 1458 insertions(+), 141 deletions(-) create mode 100644 internal/agentsessions/export_test.go create mode 100644 internal/agentsessions/pi.go create mode 100644 internal/agentsessions/pi_test.go create mode 100644 internal/tui/session_stale_picker_test.go diff --git a/internal/agentsessions/activity_test.go b/internal/agentsessions/activity_test.go index d6c0e9b6f..3e31f5baf 100644 --- a/internal/agentsessions/activity_test.go +++ b/internal/agentsessions/activity_test.go @@ -50,7 +50,7 @@ func TestTheSummaryNamesFilesCommandsAndSearches(t *testing.T) { lines = append(lines, claudeToolLines("t3", "Bash", `{"command":"go test ./..."}`, "PASS", false)...) lines = append(lines, claudeToolLines("t4", "Grep", `{"pattern":"handleResume"}`, "3 hits", false)...) - events, err := translateFamily1("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) + events, err := translateFamily1At("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) if err != nil { t.Fatal(err) } @@ -78,7 +78,7 @@ func TestAFailedCallDoesNotClaimItReadTheFile(t *testing.T) { "File does not exist.", true)...) lines = append(lines, claudeToolLines("t2", "Read", `{"file_path":"/w/parser.go"}`, "package main", false)...) - events, err := translateFamily1("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) + events, err := translateFamily1At("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) if err != nil { t.Fatal(err) } @@ -111,7 +111,7 @@ func TestEverySummaryEventSurvivesTheDigestIntact(t *testing.T) { `{"file_path":"/w/a/very/long/directory/name/that/eats/budget/file`+itoa(i)+`.go"}`, "ok", false)...) } - events, err := translateFamily1("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) + events, err := translateFamily1At("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) if err != nil { t.Fatal(err) } @@ -238,7 +238,7 @@ func TestTheSummaryReachesTheModel(t *testing.T) { } func TestASessionWithNoToolCallsGetsNoSummary(t *testing.T) { - events, err := translateFamily1("", writeTranscript(t, + events, err := translateFamily1At("", writeTranscript(t, `{"type":"user","cwd":"/w","message":{"role":"user","content":"hello"}}`, `{"type":"assistant","message":{"role":"assistant","content":[{"type":"text","text":"hi"}]}}`, ), ReadOptions{Cwd: "/w"}) @@ -258,7 +258,7 @@ func TestAnUnknownToolSchemaDegradesToACount(t *testing.T) { lines = append(lines, claudeToolLines("t1", "MysteryTool", `{"wibble":"/w/secret.go","flim":3}`, "ok", false)...) lines = append(lines, claudeToolLines("t2", "MysteryTool", `{"wibble":"/w/other.go"}`, "ok", false)...) - events, _ := translateFamily1("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) + events, _ := translateFamily1At("", writeTranscript(t, lines...), ReadOptions{Cwd: "/w"}) summary := joinedSummary(t, events) if !strings.Contains(summary, "MysteryTool x2") { @@ -276,7 +276,7 @@ func TestRepeatedWorkIsNotListedRepeatedly(t *testing.T) { for i := 0;
