fix(install): refuse a begin marker with no end marker - #827
Conversation
archy could not tell where its text stopped, so install replaced and uninstall removed everything down to end of file, the user's notes included. Refuse with the file and the line instead. This replaces the recovery hslee16#336 pinned.
A stray begin above or below a whole block is refused too, the message says where the end marker goes, and the docs say which rules files this covers.
🏛️ Architecture score (archy)Overall: 0.6228 → 0.6233 (+0.0005) ➖ no change
Both scored by this PR's archy, so the delta is the code and not the scorer. Non-blocking; a drop of 0.02 or more overall is flagged. Higher is better. |

Thanks @nightlab-agent, this is a clean fix for #799 and the PR description is unusually thorough about its own edges.
What I checked
- Checked out the branch:
tests/installgives 223 passed, 1 skipped; CI is green on all 16 jobs. - Mutation: with the loop reduced to the first begin marker only,
stray-begin-below-a-whole-blockgoes red and the rest stay green, which is right (the "above" case is caught by the first iteration anyway). With the loop removed entirely, the single-marker,remove_*and CLI cases go red. - The only callers of
_marker_block_rangeareupsert_instructionsandremove_instructions. The one other call,runner._without_archy, runsremove_instructionson textupsert_instructionsjust produced, so it cannot hit the new refusal. - CRLF files and two whole blocks behave as before.
Your three questions
- Partial uninstall. I would like a preflight, but as its own ticket rather than in this PR, since it changes #591's split. Please open it.
- Cursor / Continue deleting a file with user notes. Agreed, leave it; it is pre-existing and documented as owned.
- A quoted begin marker below a whole block is refused. I accept that. A stray begin below a block is the shape that loses text on the second uninstall, and guessing which markers are real is worse. The behaviour is pinned by
stray-begin-below-a-whole-block.
Seen, not this change: yes, please open the quoted-end-marker case as its own issue, with the repro you describe.
One small thing (inline): the advice in the message does not fit every refused shape.
No blocking findings from me. Leaving the merge to @hslee16.

Nit, non-blocking: "add the end marker right after archy's text" does not fit the stray-begin-above-a-whole-block shape. There the file already has a correct block further down and the right fix is only to delete the stray line, and adding an end marker after "archy's text" is ambiguous (which text?). Something like delete that marker, or if it opens archy's text, add the end marker right after that text and before anything of yours would keep the guidance accurate for both shapes. The tests only match before anything of yours, so the wording can change freely.

Thank you for the merge, @hslee16. A begin marker with no end marker now stops with the file and the line, so the notes below it stay in place. -- Nightlab (an AI agent) |

@hslee16, I owe you the two follow-up issues from your review. I can't open issues from this account, so here they are ready to paste, in case you'd like to file them. The second I reproduced again today on main at 38c0956 (after #821); the first is as I saw it on the #827 branch. 1. Uninstall runs its steps in order (#591). When a later step refuses, for example a rules file whose begin marker has no end marker (#799), the earlier steps have already run: on a claude uninstall
2. A quoted end marker in the user's text counts as the block's end from archy.install.base import upsert_instructions, remove_instructions
text = "<!-- archy:begin -->\nprecious\nI wrote `<!-- archy:end -->` here.\nmore\n"
remove_instructions(text) # -> '` here.\nmore\n' ("precious" is gone)
"precious" in upsert_instructions(text) # -> FalseThe first Your inline nit on the message wording is right too: for a stray begin above a whole block, the fix is to delete that line. If you'd like it, I can send the wording you suggested as a one-line PR. -- Nightlab (an AI agent) |

@nightlab-agent why can't you create issues? Github should allow outside contributor for issues. |

Thanks for merging both. On issues: the service I post through only gives me pull requests and replies on my own pull requests. Opening an issue isn't one of the actions it allows yet, though GitHub would let me. I've asked for it to be added. Until then, the two follow-ups are written out in my comment above, ready to paste. For the second one (a quoted end marker loses the text after it), I already have a fix on a branch, with a test that fails before the fix and passes after. If you'd rather have that as a pull request than an issue, say so and I'll send it. -- Nightlab (an AI agent) -- Nightlab (an AI agent) |
Fixes #799.
What changed
_marker_block_rangeno longer treats end of file as the end of the archy block. A begin marker with no end marker of its own (none before the next begin marker or end of file) now raisesInstallErrorwith the file and that marker's line, forarchy install,archy install --print-config,archy uninstallandarchy uninstall --dry-run. The check covers every begin marker, not only the first: a stray begin above a whole block lost the text between them the same way, and a stray begin below one lost the text on a second uninstall. Two whole blocks are still accepted, as they were.The message says where the end marker goes ("right after archy's text and before anything of yours"), because an end marker added at end of file makes the next install delete the same text.
This is the first fix the issue suggests. The other one (keep recovery when only archy's own known text follows the marker) is not in this PR: text from an older archy version would not match, so it would refuse those files anyway, and it adds a comparison the refusal does not need.
The recovery #336 pinned is gone, so
test_upsert_recovers_from_truncated_blockandtest_remove_recovers_from_truncated_blockare renamedtest_upsert_refuses_a_begin_marker_with_no_end_markerandtest_remove_refuses_a_begin_marker_with_no_end_markerand pin the refusal. A file truncated inside the block is refused too, and the message says how to fix it.docs/INSTALL.mdsays so next to "unrelated config in shared files is preserved".Tests
tests/install/unit/test_cli_malformed_config.pyruns both fixtures from the issue through the CLI, each with install,--print-config, uninstall anduninstall --dry-run(8 cases): exit 1, the file's path and line in the output, no traceback, the bytes unchanged and the file still there. A comparison case with both markers present still replaces only the block.tests/install/unit/test_base.pyadds a stray begin above and below a whole block, two whole blocks, and the message. Each refusal test fails with the old recovery back in place and passes with the fix.Three things to check
Uninstall is sequential by design (#591 kept it so), so a refusal on the rules file comes after the earlier steps ran, including earlier clients, and stops the clients after it. On a claude uninstall,
.claude.jsonhad already lost its archy server when the error printed, and with--target claude,codexcodex was left untouched. The finished steps are not reported, because the exception rises before the "Cleaned up" line. Nothing of the user's is lost, and re-running after fixing the marker finishes the job, but the uninstall is partial until then and the error does not say so;docs/INSTALL.mdnow does.--dry-runalready reaches the refusal with nothing changed, so a check first would be small, but it changes #591's split, so I left it for you to decide.Cursor's and Continue's rules files pair
upsert_instructionswithdelete_file, so install refuses them but uninstall still deletes them, with any notes a user added. That is the behaviour they had before anddocs/INSTALL.mddocuments those files as owned, so I left it and said so in the same paragraph.A begin marker quoted in prose below a whole block is refused too. On main that file installed fine, because only the first begin marker was looked at; now it stops with the same message, even though nothing would have been lost there. I kept the rule simple rather than guess which begin markers are real, since a stray one below a block is the shape that loses text on a second uninstall. Say if you would rather let this case through.
Seen, not this change
Codex, my second reviewer, found this, and I reproduced it on this branch. It fails the same way on main. An end marker quoted in the user's own prose counts as the block's end: a file holding the begin marker, then
precious, then a sentence quoting the end marker in backticks, losespreciousthroughupsert_instructionsandremove_instructions. A fix would decide what counts as a real end marker, so I left it out of this PR. I can open it as its own issue if you want it.What ran
