The comment is accurate and honest, which is good. The practical effect is that on Windows a cancelled plan kills
git.exeonly. Helper processes such as credential helpers or a spawned pager can survive and keep running against the worktree.WaitDelaystops the hang, but not the orphan.Windows supports the equivalent guarantee through a Job Object with
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE, or throughCREATE_NEW_PROCESS_GROUPplus ataskkill /Tstyle cancel.

The comment states "EXACTLY ONE PLACE BUILDS A SUBPROCESS IN THIS PACKAGE." A substring scan cannot support that claim:
- False negatives: it misses an aliased import such as
osexec "os/exec", a directexec.Cmd{Path: ...}literal, andsyscall.StartProcessoros.StartProcess.- False positives: it matches the text

worktrees.goand the exact argument spellingexec.CommandContext(ctx, name, args...)at line 84. Renaming thenameparameter, or moving the constructor torun_git.go, fails the test with a misleading message.Parse with
go/parserand walk call expressions instead. That removes the comment and string false positives and lets you match the enclosing function name rather than a file name.

description where applicable.
In `@internal/memory/memory.go`:
- Around line 179-186: Update the extension check in the directory-entry loop
around Read so it uses an exact comparison with fileExt instead of
strings.EqualFold. Keep the existing name trimming and Read flow unchanged,
ensuring only files whose stored extension matches the lowercase extension are
processed.
- Around line 314-329: Update splitFrontmatter to normalize CRLF line endings
before checking the frontmatter prefix and terminator, while preserving the
existing description extraction and body trimming behavior. Add a regression
test covering CRLF content, including the description and delimiters, and verify
it passes on all supported platforms.
In `@internal/tools/memory.go`:
- Around line 98-114: Update the safety text for the memory tool’s safety field

message disclose the destructive delete path.
- Around line 75-86: The memory read flow around the unnamed-memory list branch
must resolve scope once, return any resolution error, and filter
memory.List(tool.paths) to the resolved scopes before rendering; named reads
should reuse the same resolved scopes. In internal/tools/memory.go lines 75-86,
update the read handler accordingly. In internal/tools/memory.go lines 157-166,
update memoryScopes to return both scopes only for an empty argument and report
unrecognized values so memoryWriteTool and reads consistently reject invalid
scopes.
- Around line 75-77: Update the empty-name branch in Run to honor the resolved
scope by filtering the memory.List result to the requested scopes before
rendering it, rather than returning both stores unconditionally. Add the slices
import as requested and reuse the existing resolved-scope values and
renderMemoryList flow.
- Around line 71-73: The memory availability guard in the relevant tool handler
must validate tool.paths.Root, treating blank or whitespace-only values as
unavailable via strings.TrimSpace(tool.paths.Root) == "". Update the condition
before any memory listing or reading, and add a regression test covering
populated ProjectDir/LocalDir with a blank Root.

leaving the existing cancellation and WaitDelay assertions unchanged.

Add a regression assertion for the locale pin, and compare Dir to the value passed in.
Two gaps in this constructor test:
- Nothing asserts
LC_ALL=CandLANG=C. The locale pin is the behavior change that keepslockWorktreeable to match "already locked". A future edit can drop the two entries and every test here still passes. command.Dir == ""only proves the field is non-empty. It passes if the constructor writes the wrong directory.Dirholds the exact string that the test passed, so a direct comparison needs no path canonicalization.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Bound the liveness poll by a deadline, and kill the grandchild if Wait times out.
Two failure-path problems in this block:
- The poll at lines 107-115 allows 50 iterations of 20 ms, so about 1 second. The pid wait loop above uses a 10 second deadline for the same class of timing.
SIGKILLdelivery to a group, plus reaping of a grandchild that init has adopted, can exceed 1 second on a loaded CI machine. The test then reports a survival that did not happen. Use a deadline, consistent with lines 70-80. - If the
selectat lines 96-100 hits the 15 second timeout,t.Fatalruns before any cleanup. The grandchild keeps running for the rest of itssleep 60, and the test binary leaks it.

}One known limitation is worth a short comment here: syscall.Kill(pid, 0) identifies a process by pid, so pid reuse can make a dead grandchild look alive. That is inherent to pid-based checks and does not need a fix in this test.

Ran this on Windows, which is what you asked for. go build ./..., go vet, gofmt clean, and internal/memory plus the memory tests in internal/tools pass here.
The containment thesis holds, and that is the important part. I traced every filesystem operation in memory.go and each one is on the handle: List via handle.Open + ReadDir, Read via handle.ReadFile, Write via MkdirAll/RefuseReparse/CreateTemp/Rename, Forget via RefuseReparse/Remove. The only pathname-resolved calls are the two inside pathjail.Open, which is the declared boundary from 1/3. Three junction attacks were all refused: at the .zero ancestor, at the note's own file position, and at the scope directory itself, which is the one MkdirAll creates before RefuseReparse runs. Nothing escaped. The publish path is sound too, both post-CreateTemp error branches remove the temp, and a hand-planted .tmp is not listed as a note.
Concurrency is fine as built: 16 concurrent writes to one note, 16 to distinct notes, and 3000 writes against 6 readers all came back clean, last-writer-wins.
Three things to fix before 3/3 wires this up.
1. The name allow-list admits Windows reserved device names, and one such note breaks git for the whole repo
^[a-zA-Z0-9_-]+$ accepts con, prn, aux, nul, com0-9, lpt0-9. The store itself handles them fine, which is what makes this easy to miss: os.Root addresses the file relative to a directory handle and bypasses Win32 device parsing, so con.md is created, read and listed like any other note.
Git is what refuses it. I reproduced this from scratch outside the worktree:
$ git add -A
error: open(".zero/memory/con.md"): No such file or directory
error: unable to index file '.zero/memory/con.md'
fatal: adding files failed
exit=128
$ git diff --cached --name-only (empty)
$ git status --short
?? .zero/
?? README.md
git add -A stages nothing, including the user's own unrelated edits, and status never names the file, so there is no path from the symptom back to the cause. It reproduces in local scope too, which is the tool's default, because nothing in this PR writes a .gitignore.
The other direction is worse: a note named con committed from macOS cannot be checked out on Windows at all. A clone fails with fatal: unable to checkout working tree and leaves an empty tree, so a Windows contributor gets no repo, not just no note.
It is one extra check in ValidName, case-insensitive, alongside a case in escape_test.go.
2. Two names differing only in case are one note, and one silently eats the other
ValidName does not fold case, but Windows and default macOS APFS do. Saving Findings then findings leaves a single file with the second body and no error. Read then labels the result with the name the CALLER asked for rather than the name on disk, so the model can be handed memory "Findings" containing the body of findings, while the listing shows only findings.
The delete path is sharper than the overwrite: memory_write {"name":"findings"} with content omitted removed Findings.md, a note the caller never named.
internal/specialist already solved this exact shape with ^[a-z][a-z0-9-]{0,63}$, which makes the collision unrepresentable. Worth matching, since the commit message says the rule is borrowed from the plan store anyway.
3. CRLF frontmatter is silently unparsed
splitFrontmatter gates on strings.HasPrefix(content, "---\n") and strings.Index(rest, "\n---\n"). With CRLF the fourth byte is \r, the prefix test fails, and the whole frontmatter block falls through into the body. Project-scope notes are checked in, and Git for Windows defaults to autocrlf=true, so a note that round-trips through a clone comes back with its header rendered as content and no description. Accepting \r\n in that split is the fix.
Smaller, not blocking
TestWritingRefusesToFollowASymlinkskips on Windows, so on the one platform you asked me to scrutinise the file-position reparse guard has no coverage. The guard does work there, I confirmed bothWriteandForgetreturnErrIsSymlinkagainst a junction namedevil.md.escape_test.goalready has alinkDirhelper that uses a junction; reusing it here closes the gap, and it is the only test of that guard.memory_writewith empty or whitespace content deletes, behind a tool whose prompt says "Saves a note that future sessions will read and believe". No preview, noChangedFiles, and the grant is tool-wide, so one approval covers every later delete. A separatememory_forget, or at least an explicitdelete: true, would stop an empty-string bug erasing a note.- A temp orphaned by a process crash between
CreateTempandRenameis never swept. Nothing lists it, but in project scope it gets committed. localscope lands in the working tree with no.gitignoreanywhere in this PR, so "this machine only" notes show up as untracked files in everyone's status.
Checked and clean, so you do not have to wonder
Output ceilings hold (a 65 KB note reads back truncated at 64,000 with a spill file), secrets in a note body are redacted through the registry boundary, frontmatter injection from the body does not reach the listed description, MAX_PATH is fine at 314 chars, nothing assumes forward slashes, and List correctly ignores stray .tmp files, extensionless files, directories and a junction named linked.md. Registration really is absent, so this is dead code until 3/3, which is why none of the above is P1.
Good change and the security core is right. Happy to re-run on Windows once these are in.

Approving at 2766ade2. Ran it on Windows again.
The Windows coverage gap is genuinely closed, which is the one I most wanted to see. TestWritingRefusesToFollowALinkAtTheNotePosition now RUNS here instead of skipping:
=== RUN TestWritingRefusesToFollowALinkAtTheNotePosition
--- PASS
Using linkDir so it is a junction on Windows and a symlink elsewhere is the right call, and covering Forget as well as Write matters because each has its own RefuseReparse. That guard now has real coverage on the platform where the attack needs no privilege.
The name rule closes the git hazard without overshooting. I checked the question I actually care about, which is not "does it reject con" but "can anything git refuses to index still get through":
- rejected:
con,CON,Con,prn,aux,nul,com0-com9,lpt0-lpt9in every casing, plusFindings,NOTES,Note,my_note,1note,-note - still accepted:
console,nullable,com10,lpt10,auxiliary,printer,conventions,findings,note-2
Keeping the reserved list separate from the pattern is right, and so is the reasoning: the pattern says which characters may appear, the list says which otherwise-legal spellings git cannot carry. Two different rules, and folding them together would have made console collateral.
Adopting ^[a-z][a-z0-9-]{0,63}$ also makes the case collision unrepresentable rather than handled, which is the only real answer to the delete case. There is no way to resolve memory_write {"name":"findings"} deleting Findings.md after the fact.
One failure on my machine, and it is not yours. TestExecCommandForegroundServerReturnsSessionAndServesHTTP in internal/tools fails here, consistently rather than flakily. It is pre-existing: this PR does not touch exec_command, and I ran the same test on a clean checkout of origin/main and got the identical failure, a foreground server not printing its listening address inside the deadline. Environmental on this box. internal/memory is green, and so is everything else.
Agreed on the three you deferred to 3/3, and the reasoning is right rather than convenient. memory_write deleting on empty content is a tool-contract change, and changing that contract twice would be worse than changing it once at the point registration makes it real. The .tmp sweep and the local scope .gitignore become user-visible at the same moment for the same reason. Leave them there.
Base is exactly current main (2d2450e9), go build ./... and gofmt clean.
Three rounds and every finding closed with a regression rather than a patch. The device-name one only existed because the store handles those names perfectly well and git does not, which is a genuinely awkward place for a bug to hide.

It still quoted the old pattern from before the fix, which is where the "stated contract" came from. That is my drift, and I have updated the description to state For the record the rule is deliberately two rules, as @Vasanthdev2004 noted: the pattern says which characters may appear, the reserved-device list says which otherwise-legal spellings git cannot carry.

Reviewed the latest head (ffc778ef). The CRLF, Windows reserved-name, case-collision, cross-platform write/delete link coverage, and listing-order fixes all look good.
There are still several blockers:
- Final-file symlink reads are still followed. I reproduced
.zero/memory/linked.md -> ../../secret.txt;Read(..., "linked")returned the target contents instead ofErrIsSymlink.Readneeds the same final-component reparse refusal as write/delete, with a regression covering a file symlink rather than only a directory junction. - The 64 KiB limit is write-only. A handwritten or checked-in note larger than
maxNoteBytesis loaded successfully, andListreads every complete note. Please bound reads before allocation and make listing read only bounded metadata. - Invalid scopes silently broaden access. A named read with
scope: "invalid"searches both stores, while a list ignores a valid requested scope and always lists both. Resolve scope once, reject non-empty invalid values, and apply it to both paths. - Operational/security errors are presented as absence. Named reads continue on every error and report
no memory named;Listsimilarly discards open/read errors. OnlyErrNotFoundshould be treated as a miss; other failures need to reach the caller. This likely requiresListto return an error-capable result. localis not currently machine-only. It is stored at.zero/memory/local, and that path is not ignored, so the default write appears in git status and can be committed. The earlier #829 follow-up is now closed and no third split is open, so this needs a concrete resolution before the tool is wired.- Empty or omitted content deletes under a save-oriented approval. The approval reason says only that the tool saves a note, but an empty/whitespace payload calls
Forget. Please require an explicit delete operation (or a separate delete tool) and disclose deletion in its approval.
The PR description also claims memory tests in internal/tools, but this split includes none; the scope/error regressions above belong there.
The current Windows and security-check failures appear unrelated to this feature: this branch is still based on Go 1.26.5, while current main uses Go 1.26.6 for the newly reported standard-library vulnerabilities. Rebasing onto current main should resolve those checks.

Reviewed at ffc778ef. anandh8x posted six blockers a few hours ago and I am not going to restate them; treat his list as live. This adds one he did not have, and sharpens three of his where the mechanism turns out to be different from the description.
The new one: an omitted content field deletes the note, behind a prompt that says "Saves"
content is not in Required (only name is), and aliasedStringArg is called with allowEmpty=true, so a call that simply leaves the field out lands in the Forget branch on strings.TrimSpace(content) == "". Ran it:
before: memory "precious" (local)\n\nkeep me
omitted content -> status=ok output="Forgot \"precious\" (local)."
read back -> Error: no memory named "precious"
whitespace content -> status=ok output="Forgot \"precious2\" (local)."
A model emitting " \n\t " destroys the note just as effectively as one asking to.
What makes this a blocker rather than a rough edge is what the human is shown when they approve it. The safety text is exactly:
safety: promptSafety(SideEffectWrite, "Saves a note that future sessions will read and believe.")The word delete appears nowhere in it. It appears in the content parameter description, which is not what gets rendered at approval time. Forget is an unconditional remove, the tool returns no copy of what it destroyed, and there is no confirmation step. So the user approves "saves a note" and gets a permanent deletion, and an "always allow" on that prompt makes it unattended.
This is latent today, since NewMemoryWriteTool and NewMemoryTool are not constructed anywhere yet. It fires on the first call once the tool is registered, so I would rather it were fixed while the tool is still dark. An explicit delete operation, or a separate tool, with the deletion disclosed in its own approval text.
Three of anandh8x's, with the mechanism corrected
His #3, invalid scope. Worth stating the sharper version: the same argument string is validated on one path and silently widened on the other, in one PR. memory_write passes the scope to memory.Scope and gets ErrBadScope. The read path goes through memoryScopes, which has no error return and whose default arm maps every unrecognised spelling to [project local]. Separately the listing path calls memory.List(tool.paths) unconditionally, so a perfectly valid scope: "project" is dropped too. Resolve the scope once, in one place, and make both callers use it.
His #1, symlink reads. The asymmetry is real: pathjail.RefuseReparse is called in Write and Forget and on neither read path, and the comment claiming reads are confined too overstates the code. But the mechanism is not quite what the repro says. os.Root already refuses a link target that leaves the root, and a Windows junction is refused because its target is absolute. The reason his example reads is that ../../secret.txt resolves to a path still inside Paths.Root. Which matters, because a hard link at the note position escapes completely and needs no privilege: it carries no reparse bit, so neither RefuseReparse nor os.Root can see it. Adding RefuseReparse to Read, the obvious fix, does not close that. Worth deciding whether the containment claim is about reparse points or about identity, and then making the comment say the one you picked.
His #5, local is not machine-only. Confirmed against the tracked file, not the working tree: .gitignore on this branch is 60 lines and has no .zero entry at all. Careful verifying this inside an existing clone, because git check-ignore .zero/memory/local can report ignored from a local .git/info/exclude that never ships. The doc comment says "one .gitignore line separates shared from private" and that line does not exist yet.
Two more worth having
memory_write carries no scope-bearing argument, so DeriveScope yields nothing and the approval card cannot name the note, the scope, or the file it is about to write. Combined with the delete path above, "always allow" here is an unbounded grant over a store the model then reads back into its own prompt.
Project-scope notes are .zero/ content that arrives with a clone and gets read into the prompt unprompted. Every other .zero/ project layer is gated on workspace trust. This one is not, and the tool description tells the model these notes are to be believed.
Not yours
The Windows and security-check reds were the repo-wide vulncheck outage. #903 landed a couple of hours ago with the Go 1.26.6 bump, so a rebase onto current main clears them.

… and Gitlawb#897 Vasanth's review of this branch found that it carries OLDER copies of code under active review elsewhere, so merging it would silently revert those reviews: internal/pathjail/pathjail.go 135 lines here, 177 on Gitlawb#891's head internal/memory/memory.go 333 lines here, 539 on Gitlawb#897's head The memory copy was not merely older. Its name allow-list was ^[a-zA-Z0-9_-]+$, which lets "Findings" and "findings" collide into one file on Windows and default APFS — the case-collision bug Gitlawb#897 fixed, where a write silently replaced the other's body and a delete removed the wrong note. The reserved-device-name refusal was absent too, so a note named "con" or "nul" would make `git add -A` stage nothing and leave the repo un-checkoutable on Windows. This branch now takes those three packages verbatim from Gitlawb#897's reviewed head (which contains Gitlawb#891's), rather than keeping a fork of them. Two consequences had to be handled: - internal/tools/memory_tool_test.go asserted the OLD destructive behaviour (TestOmittingContentForgetsTheNote), i.e. it encoded the very defect Gitlawb#897 fixed. Replaced with one asserting deletion goes through memory_forget and that a save-shaped call with no content is refused rather than destructive. - internal/cli/app.go registered the read and write tools but not the new memory_forget, which would have left notes undeletable. Registered. Also merges current main, resolving the overlap with Gitlawb#890 so both features survive rather than one replacing the other: the footer keeps the fast chip AND the zeromaxing chip as independent conditions, agent.Options keeps both ServiceTier and ModelFamily, the provider-models JSON keeps both the capability keys and the probe-verdict keys, and session_controls keeps both the catalog-discovery efforts and the posture-fill decision. A merge rather than a rebase deliberately: replaying 131 commits over the overlap resolves the same regions ~30 times, and a wrong side taken once in that grind is exactly the silent revert this commit exists to prevent.

Self-review after the requested changes, at 45292e0a2bbc2e388c109e40865f06626a8392b2, rebased onto 6937a309cf00825572210a7610a1f3ea8b74c2f9.
The remaining git-discovery finding is addressed. Empty .git directories, malformed gitdir files, and references to missing git directories no longer make a non-repository workspace require Git or refuse local notes. Discovery continues past inert markers so they cannot conceal a real enclosing checkout. Repository metadata remains a candidate for the existing Git index check: damaged repositories, unavailable Git inside a repository, and tracked local notes continue to fail closed.
All six new public Write regressions failed before the fix with the expected ErrNotPrivate/Git-discovery error, then passed. Added controls retain the refusal for a tracked note below an inert marker and for a damaged real repository. Existing linked-worktree, privacy, and Windows handle-path coverage remains intact.
Validation: formatting, full vet and tests, memory/tools race tests, release build and smoke, govulncheck, and diff hygiene passed. Windows memory test binary compiled; native Windows execution was not performed locally. Advisory static lint reports four unchanged mainline findings in installtest, proxydial, and web_fetch; none are in this change. The rebase preserved all 15 prior patches according to range-diff.
No new third-party integration or dependency change. No evidence-backed defects found in the reviewed fix scope. Remote CI and independent approval must cover this new head; this self-review is not a maintainer approval.

Re-reviewed at 45292e0a. My approval at d78e5c27 was dismissed by this push, so this is a fresh look at the one commit since, which answers jatmn's P2.
It answers it as a classifier rather than a string. gitMarkerHasMetadata rules a .git entry out only when it cannot name a repository: an empty directory, a file that is not a gitdir: reference, or a reference whose target is missing or not a directory. Anything carrying HEAD, objects, refs, index, commondir or config is a candidate, and git still gets the last word on the index, so partial or corrupt metadata fails closed exactly as before. The walk no longer stops at an inert marker, which is the half that matters for privacy: a stray .git inside a real checkout cannot hide the enclosing repository. The read is bounded to 4096 bytes and follows a gitdir: reference read-only.
The new tests pin all of that from the public Write path: the three inert shapes, each with git on PATH and with PATH emptied; the stray marker inside a tracked repository still refusing; and a corrupt HEAD still refusing. I added four shapes the tests do not name and drove them the same way:
.git dir holding only a README write ok (inert)
.git dir holding only objects/ refused (partial metadata reaches git, fails closed)
gitdir: stub with CRLF, target missing write ok (inert)
gitdir: stub to an existing empty dir write ok (inert)
Yesterday's junction case, TestTheRepositoryIsFoundThroughALinkedWorkspace, still runs for real on this unelevated account and passes, so the physical-path fix I approved is undisturbed. Whole internal/memory package green here on Windows, CI 9 of 9.
One observation, not a request: a .git file that names a different repository still makes git answer for that repository, so a workspace-level stub can steer the index question away from the real enclosing checkout. That was true before this commit too, and writing that stub needs the same access as writing the store directly, so it is the same threat as the junction case and not a regression. Worth a line in the comment if you touch this again.
Approving.

lgtm at 45292e0a. jatmn's last finding is closed the right way — gitMarkerHasMetadata classifies rather than trusting a stray .git marker, and the walk continues past inert markers so they cannot hide a real enclosing checkout. Vasanthdev drove the extra edge shapes and it holds. On latest main, CI green.
jatmn's outstanding request-changes is from d78e5c27 — this head answers it. Approving.

Split 2 of 3 of #829 — durable memory
Second of the stack @anandh8x asked for on #829. Stacks on #891 (1/3, approved and green): the memory store is the first adopter of the
internal/pathjailprimitive that PR introduces.What this contains
internal/memory— a durable note store confined to apathjailhandle, so every read, write, rename and delete stays on the confined handle rather than being re-resolved by pathname (the ancestor-link classpathjailexists to close). Writes publish through anO_EXCLtemporary file, and the final component is checked for a reparse point before each write.internal/tools/memory.go— the memory tool over that store.Tool-registry registration lands with the orchestration wiring in 3/3, where the shared
registry.gochanges live.How the two layers agree
Note names are validated by an allow-list —
^[a-z][a-z0-9-]{0,63}$, the same rule the plan store uses (specialist/manifest.go) — so a name can carry neither a path separator nor a traversal. Lowercase-only is load bearing rather than stylistic: Windows and a default APFS volume fold case, soFindingsandfindingswould be one file there, and the second write silently replaced the first's body while deleting one removed the other. Reserved DOS device names (con,nul,com1…) are refused on top of the pattern, becauseos.Rootaddresses notes relative to a handle and createscon.mdhappily whilegit add -Athen fails on that path and stages nothing.nameis what becomes the temp-file prefix, so the fragment rejection added topathjail.CreateTempduring #891's review is defence in depth here rather than the only guard, and the two layers cannot drift into disagreeing.Validation

pathjailadopters, so it carries exactly the Windows path-semantics risk that produced the churn there, and I'm still on macOS. A run on your Windows machine before this goes far would be worth more than CI telling us after the fact.Part of #829.
