+Thanks for the link to the macOS standalone build workflow -- as you say it looks like `stack-botan.yaml` with `magicmime` enabled, and using Homebrew to supply some of the dependencies.  That's a useful reference for the future.
+
+Based on what I found yesterday I'm fairly sure both of:
+
+- Intel CPU (of a relevant vintage)
+- built with *exactly* Crypton 2.0.0 (ie, using `stack.yaml`, allowing Crypton 2.x.x *and* a restriction preventing Crypton 2.0.1 / Crypton 2.1.0)
+
+are required to trigger the build that crashes.
+
+Since Crypton 2.0.1 came out fairly soon after Crypton 2.0.0 and has the fix for the Intel CPU feature detection, I suspect that's an uncommon build configuration.  Likely only affecting Homebrew macOS Intel (\"Tier 3\") and Homebrew Linux Intel (\"Tier 2\" from memory), due to their (apparently mistaken) choice to block Crypton 2.0.1 in the dependency resolver.
+
+So I think this issue could be closed now, and just serve as future reference for other possible crash isues.
+
+I also agree with you it's quite hard to avoid dependencies-of-dependencies (especially recursively or where fairly key dependencies use the library/versions one would prefer to avoid).  Hopefully Crypon 2.x.x settles down a bit more now the clear \"major version\" breaking changes are done, because it looks hard to completely avoid in a network-related project.

+ date="2026-10-09T06:14:12Z"
+ content="""
+Apologies for the many comments to get here, but I suspect I've found the cause at last, in the [Crypton 2.0.1 release notes](https://hackage.haskell.org/package/crypton-2.0.1/changelog):
+
+> fix(cpu): stop reading Intel's SDBG bit as AMD's XOP, which crashed SHA-512 and ChaCha20 on Broadwell and later.
+
+which links to this [bug report on Crypton 2.0.0](https://github.com/kazu-yamamoto/crypton/issues/202) with similar crashes, that starts with:
+
+> Following the 2.0.0 bump I get SIGILL on an elder machine (i7-6700K / Skylake).
+
+Where on macOS, signal 4 is `ILL`:
+
+```
+ewen@basadi:~$ kill -l 4
+ILL
+ewen@basadi:~$ 
+```
+
+so the symptoms match.
+
+And the affected macOS Intel system (Intel Mac Mini, from 2020) I suspect is roughly the same CPU generation to be affected.
+
+So in theory rather than:
+
+```
+ewen@basadi:~$ git annex version | grep crypton
+dependency versions: aws-0.25.3 bloomfilter-2.0.1.3 crypton-2.0.0 DAV-1.3.4 feed-1.3.2.1 ghc-9.14.1 http-client-0.7.19 torrent-10000.1.3 uuid-1.3.16.1 yesod-1.6.2.3
+ewen@basadi:~$ 
+```
+
+I actually need the build to be against `crypton-2.0.1` on macOS Intel.... but the Homebrew Formula explicitly blocks that for another reason:
+
+```
+      # https://github.com/psibi/crypton-conduit/issues/5
+      \"--constraint=crypton<2.0.1\",
+```
+
+where [https://github.com/psibi/crypton-conduit/issues/5](https://github.com/psibi/crypton-conduit/issues/5) was one of the issues I noted above as a new change in the Homebrew Formula, which suggests that `git-annex` won't build (on macOS) with `crypton` 2.0.1.
+
+However I think they're confused about [what changed in `crypton` 2.0.1](https://hackage.haskell.org/package/crypton-2.0.1/changelog) (which is basically a one line fix) and are [probably thinking of `crypton` 2.1.0](https://hackage.haskell.org/package/crypton-2.1.0/changelog) (which is a much larger change), and I've [said so in the crypton-conduit issue report](https://github.com/psibi/crypton-conduit/issues/5#issuecomment-6075337746), where they noted the conflict.
+
+After forcing Homebrew locally to build with:
+
+```
+cabal v2-install --allow-newer=base,template-haskell --constraint=crypton<2.1.0 --constraint=magic<2 --constraint=QuickCheck<2.17 --constraint=persistent-sqlite +systemlib +use-pkgconfig
+```
+
+which pulls in `crypton` 2.0.1:
+
+```
+ewen@basadi:~$ git annex version | egrep 'crypton|git-annex version'
+git-annex version: 10.20261006
+dependency versions: aws-0.25.3 bloomfilter-2.0.1.3 crypton-2.0.1 DAV-1.3.4 feed-1.3.2.1 ghc-9.14.1 http-client-0.7.19 torrent-10000.1.3 uuid-1.3.16.1 yesod-1.6.2.3
+ewen@basadi:~$ 
+```
+
+I find that `git annex addurl` works again:
+
+```
+ewen@basadi:/tmp/test-annex$ git annex addurl --pathdepth -1 'https://download.2600.com/mediadownload/www.2600.com/offthewall/mp3files/2026/off_the_wall__20261006-128.mp3'
+addurl https://download.2600.com/mediadownload/www.2600.com/offthewall/mp3files/2026/off_the_wall__20261006-128.mp3 
+(to off_the_wall__20261006-128.mp3) ok
+(recording state in git...)
+ewen@basadi:/tmp/test-annex$
+```
+
+and I assume that `git annex importfeed` will probably work again too.
+
+Ewen
+
+PS: The working Homebrew bottle install on macOS ARM also has `crypton-2.0.0` as the build dependency, but since it seems to be an Intel CPU specific bug in Crypton 2.0.0, that wouldn't matter on ARM.

+For the record, I'd report this to Homebrew but they (a) officially don't support macOS Intel any longer (\"Tier 3\" as of last month), and (b) officially don't support local builds).
+
+It is however seeming like I should possibly try building 10.20261006 *without* this pinning to a PR version of `yesod-static`, as the more I look at that change in the Homebrew Formula, the more surprising it seems.

+it seems like all of those `yesod-static` / `ram` / `crypton` changes are related, but that the problems people encountered were build issues rather than a runtime issue.  (And the [unmerged yesod-static PR #1916](https://github.com/yesodweb/yesod/pull/1916/files), seems to selectively use `ram` or `memory` depending on the `crypton` version; notably it is unmerged for 4+ months.)

+But it does at least seem notable that Homebrew have changed how they're addressing those build conflicts.

+For ease of reference this is the Homebrew Formula for building git-annex:
+
+[https://github.com/Homebrew/homebrew-core/blob/main/Formula/g/git-annex.rb](https://github.com/Homebrew/homebrew-core/blob/main/Formula/g/git-annex.rb)
+
+and the only commit I see since 10.20060901 with non-trivial changes (eg, more than just source URL/sha256, bottle sha256) is:
+
+[https://github.com/Homebrew/homebrew-core/commit/b39e1cef1d46210c79163e52fbb2335864c88d37](https://github.com/Homebrew/homebrew-core/commit/b39e1cef1d46210c79163e52fbb2335864c88d37)
+
+which looks like it's trying to add two constraints on:
+
+* `yesod-static` (specifically 1.6.1.4)
+* `crypton` (specifically `<2.0.1`)
+
+and remove one other constraint.
+
+* `ram` (`<0`)
+
+Those changes reference:
+
+*  [https://github.com/yesodweb/yesod/pull/1916](https://github.com/yesodweb/yesod/pull/1916)
+*  [https://github.com/yesodweb/yesod/issues/1917](https://github.com/yesodweb/yesod/issues/1917)
+*  [https://github.com/psibi/crypton-conduit/issues/5](https://github.com/psibi/crypton-conduit/issues/5)
+
+(with the `ram` constraint apparently being removed in favour of a different constraint).
+
+Are those changes around `yesod-static` or `crypton` likely to be a cause of issues with URL downloads?

+### Please describe the problem in your own words.
+
+With the most recent version of git-annex (10.20261006) built on macOS 15 / Intel, from a Homebrew Formula (Homebrew no longer builds bottles for macOS Intel, so built locally from the Homebrew Formula) it appears that "addurl" and "importfeed" both crash with "error: git-annex died of signal 4" around the point that the download would be starting.  Other general git-annex features (eg, sync, copy, etc) seem to work okay -- whatever is happening seems to be linked to URL downloads specifically.
+
+The same git-annex version (10.20261006) does work with the HomeBrew bottle build on macOS ARM, for "addurl" / "importfeed", including with the same URLs.
+
+So my assumption is the issue is either macOS Intel specific or my local build specific (which was just "brew upgrade git-annex" that triggers the build).
+
+This was working, on macOS Intel, with a Homebrew locally built version, on the git-annex release from last month (10.20060901), up until the build of 10.20261006 (I didn't build 10.20261005 as that was superceded before I even saw it).
+
+While looking for similar bugs, I found [this 3 year old bug for addurl batch](https://git-annex.branchable.com/projects/datalad/bugs-done/OSX__58___addurl_--batch_--json_spits_out_shortened_output_string__dies_off_with_4/), which seems a similar outcome, but I can't quite figure out what the fix was (seemingly something related to libmagic), and whether a similar local build step is required again.
+
+Is there a known recent macOS Intel build environment change that might be required now to avoid this kind of crash?
+
+Is there some way I can see the build environment used to build the macOS Intel "standalone" packages to see if I can figure out what might be different?
+
+(All installed Homebrew packages are up to date on the system that did the build, and is running Homebrew when having problems.)
+
+### What steps will reproduce the problem?
+
+Build git-annex 10.20261006 on macOS Intel (15) from the Homebrew Formula.
+
+Try to "addurl" a URL in an existing git annex.
+
+Eg:
+
+[[!format sh """
+git annex addurl --debug --debug 'https://updates.cdn-apple.com/2023FallFCS/fullrestores/042-55833/C0830847-A2F8-458F-B680-967991820931/UniversalMac_13.6_22G120_Restore.ipsw'
+"""]]
+
+or "importfeed", eg:
+
+[[!format sh """
+importfeed gathering known urls ok
+importfeed https://risky.biz/feeds/risky-business error: git-annex died of signal 4
+"""]]
+
+### What version of git-annex are you using? On what operating system?
+
+git-annex 10.20061006, on macOS 15.7.9 (Sequoia) on Intel (i7).

+
+Yes, git-annex was working fine for both "addurl" and "importfeed" on the September 2026 release, built in a similar manner (local build from Homebrew Formula).  Thanks, it's been very helpful.

+Maybe I was mistaken about whether you have refs/remotes/hub-con/git-annex.
+I don't think it matters; as far as I can see there's nothing here that
+would be unexpected when there's a `git-annex forget` transition involved.
+
+But what I wonder now is if the server ever replaced its git-annex
+branch with the synced/git-annex branch that got pushed to it.

+The same could happen with a git remote that doesn't have git-annex
+installed.
+
+And that would leave synced/git-annex as the only place where new git-annex
+branch information is being communicate. The problem with that being that
+multiple clients can force push that, which can result in information sent
+by one getting overwritten by another. While the clients would eventually
+converge on a single merged git-annex branch via only synced/git-annex,
+it might take some time.
+
+I think that `git-annex sync` could deal with this better, by
+checking if the remote git-annex branch's sha is in gitAnnexIgnoredRefs.
+And if so, forcing a push to the remote git-annex branch,
+using --force-with-lease to avoid overwriting any changes that might get
+made to it at the same time.

+What's weird about your situation and I don't understand is you do not have
+a remotes/hub-con/git-annex, which would be the usual name of the remote
+tracking branch that git-annex would normally automatically merge. 
+
+You do have a local branch named hub-con/git-annex. I don't understand
+where that came from. Maybe that ought to be merged and isn't being merged,
+but you're clearly doing something unusual to have that rather than the
+regular remote tracking branch.
+
+Anyway, to dispell some of the other confusion in this bug report:
+
+`git-annex push` does not treat a failure to push the git-annex branch as
+an error since it has already sent the same information to the remote
+in a successful force-push of the synced/git-annex branch. So that is all a
+red herring.
+
+And when you ran "git annex merge hub-con", that is the wrong command to 
+merge the git-annex branch from the remote. That command
+merges a branch named "hub-con" into the current branch.

+### Please describe the problem in your own words.
+
+Really not sure what is going on since no logs tell me the story here (may be just absent ExitSuccess, which seems ignored?).
+
+I have a fresh (first to me) instance of forgejo+aneksajo (Version: 14.0.2-git-annex-dl1) would need IP to permit access ATM if needed to "sense"), where I created a blank repo, initiated git-annex branch, and I added it as a `hub-con` remote. It got its annex UUID and all good. 
+
+```shell
+❯ git config list | grep hub-con
+branch.master.remote=hub-con
+remote.hub-con.url=https://hub.centerforopenneuroscience.org/con/liab-falkor-hub.git
+remote.hub-con.fetch=+refs/heads/*:refs/remotes/hub-con/*
+remote.hub-con.annexurl=annex+https://hub.centerforopenneuroscience.org:443/git-annex-p2phttp
+remote.hub-con.annex-uuid=e9147e49-a1d5-49b1-bd50-74010d401463
+```
+
+But nomater what I do, it does not merge that remote's git-annex branch, and moreover `annex sync` has
+
+```
+push hub-con 
+[2026-10-07 13:09:57.620037708] (Utility.Process) process [2221140] call: git ["--git-dir=.git","--work-tree=.","--literal-pathspecs","-c","annex.debug=true","push","--quiet","hub-con","master"]

+push hub-con ok
+```
+
+in its output which kinda (now not sure since I do not think there is no `ExitSuccess` for the 2221164) suggests no issue and that all is pushed ok there. But branch remains detached and not pushable if I retry the command above:
+

+`git-annex export` filters the exported tree to the preferred content of
+the remote.
+
+That is not quite what's being asked for here, which is a new feature
+to generate a filtered tree. But clearly the code to create such a tree is
+all present in git-annex already.
+
+In fact, an export to a special remote does write such a tree to a git ref. 
+So a dummy special remote that didn't write any files would be one way to
+implement this. (Not a good way.)
+
+I think the question is, what command would it make sense to put this
+feature in? And this seems like a good candiate: `git-annex adjust --wanted`
+That would adjust the tree to only contain files that are preferred content
+of the local repository.
+
+That seems broadly useful. Although similarly to --hide-missing, with
+some preferred content expressions (ones using `present`), the adjusted
+branch sometimes needs to be updated when content availability changes,
+eg after a `git-annex drop`.

+* Disable ssh `authorized_keys` configurations that run [[git-annex-shell]]
+* Disable automated processes that run git-annex, such as cron jobs.
+* If you operate any git repositories that others can access,
+  disable any git hooks that run git-annex.  
+  If the security hole in git-annex might expose information in the git
+  repository, take down the git repository as well.
+* Avoid running git-annex until the security problem is fixed.  
+  Note that you can still access files stored in local git-annex
+  repositories, without needing to run git-annex.  
+  It is also possible to access files stored by git-annex on remotes
+  without running git-annex; see [[future_proofing]].
+* If the security hole involves the encryption of data that git-annex
+  stored on a remote, you could choose to [[drop|git-annex-drop]] 
+  that data from the remote to avoid it being exposed.  
+  But avoid running git-annex to do so if you know or suspect that git-annex
+  is compromised in other ways.  
+* Please report the security hole so that a fix for it can be developed in
+  git-annex.

+Right, the reason I think the mirror would need to proxy the drop to the
+original repository is that otherwise a client who dropped a file from the
+mirror would update the location log to say it's no longer in the original
+repository when it still is.
+
+But the mirror doesn't need to be able to write to the original repository.
+It would be ok for a drop from it to fail if it is unable to proxy the drop
+on to the original repository. It could choose to always make drops
+from it fail. Or it could choose to drop its local cache on a drop, and
+then fail the drop, leaving the content in the original repository. Any of
+these options would leave the git-annex branch in a consistent state.

+(I didn't cover what the mirror would do if a client tried to store an
+object on it, but similar reasoning applies.)
+
+> In my sketch of an approach, I saw the mirror repo as an ordinary node in the git-annex network. It would have its own UUID, and therefore would require (ordinary) coordinated merges of the git-annex branch.

+I had to think about in which ways this maps back onto the approach I had in mind. I think the following statement is what I keep stumbling upon:
+
+> A client dropping an object from the mirror would have it proxy the drop to the original repository, and only delete its cache if that drop succeeded.
+
+This implies a much more symmetric relationship of the source and the mirror than what I had in mind. My concept of a mirror was that
+
+- it is partial (it would mirror the refs, but not all keys -- which makes mirror somewhat a misnomer)
+- operation requires no permissions for the source other than read
+
+I like the transparent key retrieval through the mirror from the source. I like the decision making on whether to cache a key via preferred content.
+
+I do not immediately see the advantage or necessity to bind the fate of a mirrored-key to its counterpart at the source. I think this is a consequence of
+
+> Since the client sees the original git-annex branch, it only knows about the uuid in that branch for location tracking.
+
+which further implies
+
+> The mirror repository could have the same uuid as the original set in annex.uuid, so the client thinks it has the same uuid, but actually have a different uuid that is configured elsewhere. Make git-annex use that other uuid, and with annex.private set, it will never reach the git-annex branch.
+
+In my sketch of an approach, I saw the mirror repo as an ordinary node in the git-annex network. It would have its own UUID, and therefore would require (ordinary) coordinated merges of the git-annex branch. But this would enable fully independent decision making re key availability/dropping at the \"mirror\".

+
+Going off `master`, the latter issue in Annex/Balanced.hs has been resolved while Utility/Hash/Crypton.hs is still affected.
+
+On a different note, I've tried building with botan-low, which failed to build due to the same issue above, i.e. Utility/Hash/Crypton.hs gets compiled even when using botan. I would expect that using botan would remove any use of crypton.
+
+I like your work regarding the use of LLMs even in dependencies. I wasn't previously aware that there were already so many (and so widely used!) projects that included LLM generated code.

+file from a readonly remote, so that is safe enough, though not really

+I have thought of three different ways to support concurrent tests with TAP
+output:
+
+1. Include a TAP parser (or at least a parser for the subset of TAP that
+   tasty-tap uses, which does not include YAML blocks), so subtest
+   process output is gathered, parsed, and re-emitted. (Also needs a TAP
+   generator.)
+2. Add an option like `--test-portion=1/3` so the caller can run multiple
+   processes in parallel and do whatever combining they like. This is close
+   to the way subtest processes are implemented currently, so probably the
+   easiest option. Also more flexible since it can be used without using
+   TAP.
+3. Since test numbers are actually optional in TAP output. modify tasty-tap
+   to not include test numbers, and then the outputs of concurrent
+   processes can be concacenated easily. This would probably entail forking
+   tasty-tap, but it is a small amount of code, so total code would
+   probably be less than option #1.

+### Please describe the problem in your own words.
+
+crypton 1.1.0 switched from memory to ram, the latter providing the same interface with its own definitions. Thus, using memory is incompatible with crypton 1.1.0.
+
+### What steps will reproduce the problem?
+
+Build the latest release 10.20260901 against crypton 1.1.0.
+The build fails with an error message regarding mismatching types.
+
+### What version of git-annex are you using? On what operating system?
+
+* OS: Arch Linux
+* Kernel: Linux 7.2.6-arch2-1
+* GHC: 9.6.6
+* git-annex: 10.20260901
+* crypton: 1.1.0
+* memory: 0.18.0
+
+ram: 0.22.1
+
+### Please provide any additional information below.
+
+The relevant imports explicitly mention the memory module: `import "memory" ...` and `import qualified "memory" ...`. Without the explicit module mention, it would work as-is, as ram provides the same interface.

+Use case is wanting to set up a server with a git-annex repository which is
+a mirror of an original repository.
+All git refs are mirrored, using eg `git push --mirror`.
+
+So, the git-annex branch cannot diverge. Or if it does, any divergence will get
+overwritten the next time the refs mirror is updated.
+
+The mirror can contain some, but not necessarily all annex objects as the
+original repository. If a client requents an annex object that is not
+present in the mirror, it transparently proxies the request to the original
+repository. It may also, optionally, cache the object in the mirror (if 
+the mirror's preferred content configuration wants it).
+
+A client dropping an object from the mirror would have it proxy the drop to
+the original repository, and only delete its cache if that drop succeeded.
+
+It seems at first that the mirror repository would need to have
+the same uuid as the original repository. Since the client sees the
+original git-annex branch, it only knows about the uuid in that branch
+for location tracking.
+
+But using the same uuid would bring in a ton of special cases and problems.
+Just a few of them are:
+* `git-annex get` in the mirror repository would fail to get files from the
+  original repository, because the local repo uuid is filtered out of the
+  remote list in `keyPossibilities'`.
+* The mirror couldn't have its own preferred content configuration.
+
+The mirror repository could have the same uuid as the original set in
+annex.uuid, so the client *thinks* it has the same uuid, but actually have
+a different uuid that is configured elsewhere. Make git-annex use that
+other uuid, and with annex.private set, it will never reach the git-annex
+branch.
+
+In the P2P protocol, `AUTH-SUCCESS` includes the server's uuid.
+That would need to be the original repository's uuid, to avoid a
+client thinking it's talking to the wrong repository.
+
+---
+
+Concretely, a mirror could be configured like this:
+
+    git remote add original http://example.com/foo
+    git pull --prune mirror
+    git config annex.mirroring original
+    git config annex.private true
+    git-annex init
+    # that sets annex.uuid to the discovered uuid of original
+    # and it sets annex.mirror-uuid to the repo's true uuid
+    git-annex mirror --from=original # optional
+

+Note that every concurrent test job produces its own TAP output.
+To avoid that problem, in TAP mode the test suite would need to not run

+ATM outputs from `git annex test` are custom. I personally find it difficult to find results of failure etc. But what is more important is that it is difficult to script deterministic analytics on top of such results (e.g. as xfailing some specific tests in some specific contexts). I know of [TAP](https://testanything.org) protocol which I believe a number of generic testing harnesses support. May be could be some form of `--output-format text,tap` options for `git annex test`.
+There is also a somewhat related [SARIF](https://sarifweb.azurewebsites.net/) (Static Analysis Results Interchange Format), which was suggested in another scope, but not familiar with it at all in practice.

+Following is a small patch that makes import from directory, followed by get
+from the sameas rsync work.
+
+Note that, import from rsync followed by get from sameas directory *won't*
+work with this patch. The reason is that directory special remotes support
+importree+exporttree. And even if they are only configured with exporttree,
+they currently verify ContentIdentifiers when retrieiving. And when no
+ContentIdentifier is known, it will fail.
+
+So, applying this patch seems like it would need remotes like directory to
+have a separate implementation of importActions, rather than the current way
+that exportImportActions is used to implement importActions. There are not
+too many remotes that support importtree+exporttree, so maybe that is worth
+doing.
+
+The other limitation of the patch is that import from rsync followed by get
+from sameas directory that is configured with importree+exporttree still
+won't work. And this approach cannot deal with that case.

+A use case for this is having a directory special remote that is --sameas a
+rsync special remote. `git-annex import --fast` from the directory special
+remote imports the tree and that avoids needing to import from the rsync
+special remote, which would be much slower for a large data set.
+
+A second import step would be acceptable in this situation. 
+The user would need to make sure that the files on the remotes
+are unchanged from the directory import when running the rsync import.
+This seems like it could be handled as a special flag to `git-annex import`.

+It would be useful in some cases to be able to have a local git remote
+that acts as a proxy to other remotes. That is not currently supported.
+See [[!commit f98605bce7ecfa7fd155d501accb2734d3e9a422]].
+
+Supporting this could be as easy as using git-annex-shell on the path of
+the local git remote and speaking P2P protocol to it.
+
+A possible complication with that: In between uses of a local git remote,
+git-annex is careful to flush files and close handles. That is to support
+removable drives, so nothing is lost if one is ejected while git-annex is
+running, and to make it possible to unmount them. If git-annex-shell 
+has to be spun up once per file, and then shut down afterwards, that might
+be quite slow. Possible approaches to deal with that would be a) document
+that a local git remote that acts as a proxy will keep a removable drive in
+use as long as git-annex is running or b) avoid tearing down the
+git-annex-shell for a few seconds so it's still available for the next use.

+This happens because the meaning of a content identifier is dependent on
+the implementation of the special remote. Using a content identifier
+generated for a directory special remote with a rsync special remote will
+not work.
+
+So, for the --sameas remote, the content identifier is accessed using
+its annex-config-uuid rather than the annex-uuid. And that's why 
+it says no content identifier is recorded, since none has been stored
+using the annex-config-uuid.
+
+For this to work there would need to be another step taken to record
+the content identifiers for the --sameas remote. Which could be something
+like `git-annex import` from it -- except when I tried doing that, it
+doesn't record them, because it skips over already imported files.
+
+I doubt that needing a second import step would meet your needs though?
+
+It may be that the best fix for this is to prohibit initializing a --sameas
+remote with importtree=yes.

-### Please describe the problem.
-`git annex export` to a directory special remote can delete pre-existing files
-that it never wrote.
-When export encounters a path that already exists on the export remote, it does
-not overwrite it — the existing file's contents are left untouched. But it still
-prints `export <remote> <file> ok` and records the file as exported. That record
-later authorises a deletion: once the exported tree stops listing that path,
-export prints `unexport <remote> <file> ok` and removes the pre-existing file.
-So the behaviour is asymmetric in an unfortunate direction: too conservative to
-overwrite a file it does not own, but willing to delete that same file later.
-### What steps will reproduce the problem?
-Set up a directory holding data that git-annex did not put there:
-
-	mkdir -p /tmp/target
-	echo "PRECIOUS-PREEXISTING-DATA" > /tmp/target/a.txt
-	echo "ALSO-PRECIOUS"             > /tmp/target/keep.txt
-
-Make an annex whose tree happens to contain a file of the same name, plus one
-new file:
-
-	mkdir /tmp/work && cd /tmp/work
-	git init -q .
-	git annex init -q work
-	echo "DIFFERENT-CONTENT-FROM-TREE" > a.txt
-	echo "new"                         > b.txt
-	git annex add a.txt b.txt
-	git commit -qm tree
-	git annex initremote t type=directory encryption=none \
-	    directory=/tmp/target exporttree=yes
-
-Export:
-
-	$ git annex export main --to t
-	export t a.txt ok
-	export t b.txt ok
-	$ cat /tmp/target/a.txt
-	PRECIOUS-PREEXISTING-DATA
-
-Note `a.txt` was reported as exported, but its contents were (correctly) not
-overwritten.
-Now export a tree that no longer contains those files. The empty tree is used
-here for brevity; in practice this is just an ordinary change that drops a path.
-
-	$ git annex export $(git hash-object -t tree /dev/null) --to t
-	unexport t b.txt ok
-	unexport t a.txt ok
-	$ cat /tmp/target/a.txt
-	cat: /tmp/target/a.txt: No such file or directory
-	$ cat /tmp/target/keep.txt
-	ALSO-PRECIOUS
-
-`a.txt` is gone. Its contents were never exported by git-annex, and never
-existed anywhere in the annex — they are simply lost.
-`keep.txt` survives, which isolates the cause: it was never named in an exported
-tree, so no export record was created for it. Deletion follows the export
-record, and the export record was created for a file that was never written.
-### What version of git-annex are you using? On what operating system?
-10.20251215 on Linux (Manjaro, x86_64). Also reproduced with a build of
-10.20260718 from git.
-### Please provide any additional information below.
-The impact depends on what else lives in the export remote's directory. If it
-holds a checked-out git repository, the deletion can remove that repository's
-`.git/config`, `HEAD`, `refs/*`, `logs/*` and hooks in one pass — every one of
-which export had previously declined to overwrite. In a test here that took a
-working repository from 31 files to 4, after which `git log` in it reported
-`fatal: not a git repository`.
-A couple of related observations from the same testing, in case they are useful:
-* Exporting to an *empty* directory writes every file in the tree as expected,
-  so the non-overwriting behaviour above is specific to paths that already
-  exist.
-* Once export has written a file, later modifying that file on the remote and
-  re-running export does not restore it, with or without `--force`.
-I have deliberately not proposed a fix, since the right behaviour is a design
-question — whether export should refuse such a path, warn, overwrite it, or
-simply not record a file it did not write, all have different consequences for
-existing users.

+git-annex will filter the tree it exports to only the files that are
+configured to be preferred content of the remote. So you could do this:
+
+	git annex wanted android 'include=album/*'

+
+> How do I create a tree that contains the subfolder itself too?
+
+Worth noting that is a general git question really, with several valid
+answers that don't involve git-annex at all. (One easy one is to check out
+a new branch, `git rm` everything except the subfolder, and `git commit`.)
+
+And once you have such a tree stored on a git branch, you can pass that
+branch to `git-annex export`. So that's an option if you don't want to need
+to deal with git-annex's own filtering features.

+FWIW, I did add a note to the git-annex-export man page that git-annex
+expects to be the only thing writing to an exporttree=yes remote unless
+importtree=yes. So hopefully there will be less confused users. However,
+I'm doubtful that will be enough to avoid all confusion.

+So, I've also made it display a warning in this situation.

 Repeated exports are done efficiently, by diffing the old and new tree,
 and transferring only the changed files, and renaming files as necessary.
