* fix(archive): retire a capability when a change removes its last requirement
A delta whose REMOVED entries cover every requirement rebuilt the main spec
empty, and an empty spec fails validation ("Spec must have at least one
requirement"), so the archive aborted with no way forward. Pre-deleting the
main spec did not help: the delta was then treated as a create and landed on
the same empty spec.
Archive now treats an emptied capability as retired. It deletes the
capability's spec.md and any directory the deletion leaves empty, stopping
short of the specs root, and reports the removals in the totals. Nothing is
deleted unless this run actually removed a requirement, so a re-applied or
already-synced delta still leaves the file alone.
Closes #1302

* fix(archive): decide retirement from the validator and contain the deletion
Adversarial review found the original rule unsound. It retired whenever no
canonical `### Requirement:` blocks were left, but the validator counts
requirements differently: MarkdownParser accepts any `###` heading under
`## Requirements`, while the delta block parser indexes only canonical headers
and sweeps the rest into the preamble, which survives into the rebuilt spec. A
strict-valid spec could therefore be deleted on an archive that previously
succeeded. Retirement is now decided by putting the rebuilt spec to the
validator and retiring only when its sole error is that it has no requirements,
which makes "this spec could not have been written anyway" true by construction.
Also fixed:
- The directory prune walked string prefixes, but path.resolve does not resolve
symlinks and readdir/rmdir both follow them, so a symlinked capability
directory let it delete directories outside the repository. Pruning is now
bounded by real paths and refuses to descend through a symlink.
- A spec that was already requirement-less and lost nothing this run is no
longer skipped past validation; it aborts exactly as it did before.
- Deletions are deferred until every spec write has succeeded, so a later
failure cannot leave a spec already deleted.
- Retirement is recorded in `warnings`, naming any other sections the deleted
file held, so JSON consumers and humans can both see what went.
- Totals carry every applied operation; a rename applied on the way to the
removal was being dropped.
- bulk-archive guidance, the sync/archive skill specs, and the docs that
described archive as never deleting a spec.
Closes #1302

* fix(archive): close the retirement gaps a second review round found
Five adversarial reviews, mutation testing and CodeRabbit went at the reworked
retirement. The findings, all verified by repro before fixing:
- The archive-name collision check ran AFTER the spec merge, so archiving twice
in one day deleted the capability's spec and then failed, leaving the change
unarchived and the file gone. The destination depends only on the change name,
so it is now settled before any spec is written or deleted - which also closes
the same, older window for ordinary writes.
- `--no-validate` retired too, but the whole safety argument is the validator's
verdict, and that path produces none. It now writes the spec exactly as it did
before this feature existed, leaving no exception to the claim that nothing
previously working changes.
- The validator can be talked out of seeing a requirement: a stray
`### Requirements` under Purpose captures its section lookup, so a spec still
holding a real requirement reported "no requirements" and was deleted. Any
`###` heading left under `## Requirements` now vetoes retirement outright - a
reader is not fooled by the stray heading even when the parser is.
- A dangling symlink made `update.exists` false (`fs.access` follows links,
`unlink` does not), skipping the "removed something this run" guard: a run that
removed nothing deleted an entry and reported a removal. The no-target case is
now an explicit branch that never deletes, instead of an ENOENT probe.
- `findOtherSections` reported `## ` headings that were inside HTML comments and
listed duplicates; it now masks comments like every other structural scan here
and dedupes. The warning also names the `## Purpose`, which the deletion always
takes, and the resolved path when a symlink puts the file outside the repo.
- A failed `unlink` surfaced a bare errno; it now says what was being attempted
and what to do.
Tests grew from 19 to 33, killing every surviving mutant the review found:
deferral proven against a failing write (not just a failing validation), the
warnings payload, the already-gone path's output, multi-level pruning, the
`+ path.sep` boundary, a symlinked specs root, two retirements in one archive,
and `isRetirableSpec` unit-tested directly - including the two-error shape that
proves `every` rather than `some`.
Agent guidance, the three living specs and the docs now state the same
conditions the CLI applies, so a sync agent cannot delete a spec archive keeps.
Closes #1302

* fix(archive): make the write-failure test platform-neutral and the path note meaningful
Windows CI and CodeRabbit each caught one:
- `chmod 0o555` is not a write barrier on Windows, so the test that proves
deletions are deferred until every write succeeds never failed a write there:
the archive completed, the spec was retired, and the assertion blew up. It now
puts a directory where the second spec's file belongs, which fails the write on
every platform. Verified it still kills the reordering mutant.
- The "resolved to" note compared a canonicalized path against a merely resolved
one, so any symlinked ancestor - the platform's own /var -> /private/var is
enough - decorated an ordinary retirement with a path that says nothing. It now
fires only when the spec really lived outside the specs tree, which is the fact
the nominal path hides. Both directions are pinned by tests.
Closes #1302

* fix(archive): make the residual-heading veto position-independent
A third review round, scoped to the code the earlier rounds never saw.
The veto that is supposed to stop a retirement deleting hand-written content
only worked when that content sat ABOVE the first requirement. `parts.preamble`
is by definition the text before the first `### Requirement:` header; anything
after the last one belongs to that block's raw and is discarded with it, so the
rebuilt-body scan never saw it. Identical content, different position: one
aborted, the other was deleted silently. The veto now reads the original
Requirements section - preamble plus every block - so position does not matter.
Also:
- `realpath` follows a symlinked `spec.md` but `unlink` removes the link, so the
warning declared it had deleted a file outside the repo that was still there.
The note is now skipped when the target is itself a symlink.
- `findHeadings` masked HTML comments before code fences, so an unterminated
`<!--` inside a fenced example blanked the rest of the document and truncated
the very list of sections the deletion was reporting. Fence first, then
comments.
- Moving the collision check before the merge widened the window between it and
the move, where a claimed destination surfaced as a raw ENOTEMPTY and degraded
to `archive_error`. `moveDirectory` now reports that as `archive_target_exists`,
the same diagnostic the pre-flight check gives.
And a simplification the review asked for: the overlapping `retirable` /
`deletes` / `retired` booleans are now one `decideSpecOutcome()` returning
'write' | 'delete' | 'skip'. Behavior is identical - same clauses, same order -
but the fourth state that existed only as a comment is now a visible return.
Both guards were kept: the review constructed inputs where each is the sole
thing preventing a data-losing delete.
Two tests the review found wanting are gone or rewritten: one killed no unique
mutant, and one assertion straddled two editable message fragments and could
have gone vacuously true.
Closes #1302

* test(archive): canonicalize both negative path assertions
CodeRabbit caught that `expect(warnings).not.toContain(shared)` passed
vacuously: on macOS the temp root lives under /var, whose realpath is
/private/var, so the warning would print a form the assertion never compared
against. The sibling assertion on `tempDir` had the same flaw.
Both now canonicalize first, and both were confirmed to fail against a mutant -
dropping the lstat guard, and forcing the resolved-path note on - which neither
did before.
Closes #1302

* fix(archive): move a retired capability's spec into the archive instead of deleting it
Retiring a capability was the first case where archiving deleted a file
under `openspec/specs/`. Nothing in the repo had ever removed spec content
before, so the blast radius of a wrong verdict was a lost file with only
the reflog to recover it.
The spec now moves instead. It is staged into the change directory, which
the archive step renames onto the archive path moments later, so it comes
to rest at `<archive>/retired-specs/<capability>/spec.md` beside the
proposal and tasks that retired it. `git` records a rename, and bringing a
capability back is a `git mv` from the archive.
Staged into the change rather than written to the archive path after the
move, because the archive path must not exist yet and the ordering is
safer: if a later step fails, the spec sits in a change that is still
active and a rerun carries it through, versus stranding the live specs
tree without a spec it still needs.
A symlinked `spec.md` is copied by content and its link removed, rather
than moved: relocating the link itself would archive a relative path that
no longer resolves from where it landed. A spec already staged by an
earlier aborted run is never overwritten - it is the only copy once the
live one moves.
The retirement verdict, its guards, and the deferral until every write has
succeeded are all unchanged.

* fix(archive): clean up staging directories when a retirement move fails
The staging directories are created before the move, so any failure left an
empty `retired-specs/<capability>/` behind. That folder then rode into the
archive with the change, where it reads as a retirement that never happened -
a spec was supposedly retired here, and there is nothing to show for it.
The failure path now prunes back up to the change directory. Only empty
directories go, so a capability the same run already staged next to the
failing one is untouched, and the guard that refuses to overwrite a staged
spec still stops at a non-empty destination.
Both cases are covered by tests that fail without the prune: a dangling
symlink is the reproducible post-staging failure, since lstat sees a file and
the copy then follows the link and finds nothing.

* docs(archive): say "moved" where the retirement path still said "deleted"
Three leftovers from the deletion version: the `residualRequirementHeadings`
comment, `pruneEmptyDirs`'s `mainSpecsDir` parameter - now a boundary that is
the change directory on the cleanup path, not the specs root - and a sentence
in writing-specs.md that used "deleted" for the requirement and then again for
the file, two lines apart.
No behavior change.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(archive): roll back a staged copy when the live spec cannot be removed
Both non-atomic retirement routes - a symlinked main spec, and the
EXDEV/EPERM rename fallback - copy the spec into staging first and remove
the original second. A copy that landed before an `unlink` that failed left
the spec in TWO places, and the staged one then tripped the "already
staged" guard on every rerun. The error told the caller to rerun the
archive, and the rerun could never work.
Reproduced at the previous head with a symlinked `spec.md` in a read-only
capability directory: `copyFile` succeeded, `unlink` returned EACCES, and
both copies remained.
The failure path now deletes the destination this attempt created, so the
capability is left exactly as the attempt found it and the rerun works. The
rollback is gated on a flag set only after the destination is proven free,
so a spec staged by an EARLIER run is never the thing removed - the
overwrite guard still fires ahead of it and rolls nothing back. A partially
written copy is cleaned by the same call.
The message no longer promises more than it delivers: it reports that the
spec is still in place, or names the leftover copy when the rollback itself
failed.
Regression tests cover both routes and assert the rerun succeeds, not just
that the copy is gone. Both fail without the rollback. The cross-device
route injects EXDEV, which cannot be provoked inside one temp directory.

* test(archive): run the rename-fallback rollback case on Windows too
The two post-copy rollback cases shared one `skipIf(win32)`, inherited from
the symlink case, which needs privileges Windows does not grant by default.
The rename-fallback case uses regular files and spies only, and the sibling
errno it stands in for - EPERM - is the Windows case, so skipping it there
left that route untested on the platform that produces it.
Skipping is now per-case.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(archive): claim the retirement destination atomically
`fs.access` followed by a write is not an ownership claim. Two concurrent
retirements both saw the destination free and both set `destIsOurs`; one
moved the spec into staging, and the other - equally convinced the file was
its own - rolled it back out. The source and the staged copy both ended up
gone. Reproduced at the previous head in 36 of 40 iterations.
The claim and the content now arrive in one syscall: `copyFile` with
`COPYFILE_EXCL` fails with EEXIST rather than overwriting, so exactly one
caller can ever own the path. That is also the check that refuses to
clobber a spec an earlier aborted run staged, now decided atomically rather
than by a separate look beforehand.
The losing caller fails two ways, and both used to destroy the winner's
file. EEXIST is the obvious one. ENOENT is not: `copyFile` opens the source
first, so a loser that arrives after the winner removed the source fails
before creating anything - and treating that as "a partial copy of mine"
unlinked the winner's file. Neither errno now claims ownership. Fixing only
EEXIST left 4 of 40 iterations still losing both copies.
Copying rather than renaming is what makes the claim possible: `rename`
overwrites silently on every platform, so it cannot tell "I created this"
from "I destroyed someone else's". It also crosses filesystems, which
retires the EXDEV/EPERM fallback, and reads a symlink's content rather than
moving the link - so the two routes collapse into one shape.
Regression asserts the invariant over 25 rounds: exactly one caller
retires, the spec survives once and intact, and the source is gone. It
fails against the old access-then-write shape.
Not crash-safe, which is a weaker promise and now documented: a process
killed between the copy and the unlink leaves the spec in both places, and
the next run refuses rather than guessing which to keep.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(archive): take retirement ownership from an exclusive create, not an errno
Claiming the destination with `copyFile(..., COPYFILE_EXCL)` closed the
concurrent race but kept reading ownership out of a failure code, and that
cannot be made correct however the errnos are partitioned. An errno says
what went wrong, not what was created: a source-side EACCES is
indistinguishable from a partial copy of our own, so the cleanup deleted a
recovery copy an earlier run had staged - the last remaining copy of a spec
whose live file could not even be read.
Reproduced at the previous head with an unreadable `spec.md` and a
pre-existing `retired-specs/legacy/spec.md`: the staged file was destroyed.
Ownership now comes from `open(dest, 'wx')`. O_CREAT|O_EXCL returns a
handle exactly when it created the file, so the question is answered by the
syscall instead of inferred afterwards, and every failure path leaves the
flag false. EEXIST remains the refusal that protects an earlier run's copy,
now decided by the same operation. Content is written through the claimed
handle, as bytes, and the handle is closed before any rollback so Windows
can unlink it.
The regression uses real mode bits, skipped on Windows and under root: the
defect was a source-side errno being read as proof about the destination,
and stubbing a JS-level read cannot reproduce it, because the copy it has
to fool never went through one. Verified it fails against the errno-
inference version.
All three findings on this path now hold together: the pre-existing copy
survives, 0 of 120 racing iterations lose a spec, and a post-copy unlink
failure still rolls back and reruns cleanly.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(archive): keep the staged copy when the source is already gone
The rollback exists for a copy that landed while the source survived - the
two-places state that blocks every rerun. It must not fire once the source
is gone: at that point the staged copy holds the only remaining content, and
the end state the retirement was reaching for is already reached.
An external delete landing between the read and the unlink produced exactly
that, and the rollback destroyed the spec outright - `retired: false`, no
live file, no staged copy, content gone.
`unlink` returning ENOENT is now a success rather than a failure to roll
back. Every other errno still throws: the source is still sitting there, and
leaving the staged copy beside it is the state that blocks a rerun.
Found reviewing the finished path rather than reported - the same class as
the three review findings before it, all of them the rollback reaching a
copy it should not have. Regression verified against the unconditional
unlink.
Also corrects a doc line that still credited the copy with claiming the
destination; the claim is the exclusive create.

* refactor(archive): gate retirement on a declared marker, drop retired-specs/
Reworks #1302 to follow the design that already exists instead of adding one.
The move-into-the-archive approach introduced two things OpenSpec did not
have: capability retirement as a lifecycle state, and `retired-specs/` as an
on-disk convention no schema declares - which a future unarchive command
would have to know about. Its whole justification was preserving content that
two existing mechanisms already preserve: the archived change carries the
delta naming every REMOVED requirement with its Reason and Migration, and git
carries the file. The approach even conceded the point by advertising `git mv`
as the recovery path.
The issue itself proposed neither. It asked for a delete, or an explicit
retirement marker. This does both: archive deletes the emptied spec, and only
when the change declares `retire_capabilities: true` in its `.openspec.yaml`.
`skip_specs` is the precedent. The marker reader is the same function,
parameterised by key, so the two can never drift apart on what counts as
honorable metadata - a marker in unparseable YAML, or one whose schema does
not load, is not a marker in either case. An explicit `false` is not an
unhonorable marker, it is simply undeclared.
Without the marker nothing changes: the unwritable spec aborts the archive
exactly as before, except the abort now names the marker as the way out - and
says nothing about it when retiring would not have made the spec writable
anyway, so it never sends an author after the wrong fix. Applying REMOVED
already deletes requirement content from a main spec, so deleting the spec
once nothing is left is that same operation carried to its end.
Every guard survives: the validator's verdict, the residual-heading veto,
something-removed-this-run, and never under --no-validate. What goes is the
exclusive claim, the rollback, the staging directories, and the four
data-loss windows they created across four review rounds. Net 307 lines
smaller than the move.

* chore: regenerate parity hashes over the merged sync-specs template
#1482 and this branch both edit the sync-specs template, so the merged
template needs its own hash - neither side's committed value describes it.
* docs(archive): correct claims the redesign left false, and bump to minor
Review findings, all verified before fixing:
- `pruneEmptyDirs`'s doc claimed "two callers, two boundaries", naming the
change directory as the second. That was the staging walk from the move
design; there is one caller. The boundary stays a parameter, and the comment
now says why.
- Three comments still described the retirement as moving the file somewhere.
It deletes it.
- The sync skill told agents the retirement condition includes "no other
`###` headings or prose" and then claimed "openspec archive draws exactly
these lines". It does not draw the prose line: a main spec with loose prose
under `## Requirements` retires and is deleted, and the prose is not named
in the warning, which reports `## ` sections only. Verified against the
built CLI. The condition now states what the CLI enforces, and the template
tells the agent to read that prose back to the user, since the CLI cannot
see it for the agent.
- `docs/concepts.md`'s `.openspec.yaml` field list omitted the new marker -
the one place a user goes to learn what that file may hold.
- `docs/cli.md`'s `--no-validate` row did not mention that it disables
retirement, though the row two lines down documents retirement.
- Bumped patch -> minor. `skip_specs`, the marker this one mirrors, shipped as
a minor change in 1.7.0 (#1399); this adds a metadata field and an archive
outcome on the same footing.
No behavior change.

* fix(archive): refuse to retire a spec with a second Requirements section
Four review agents ran against this branch. Two data-loss findings, both
reproduced before fixing.
1. A spec with a SECOND `## Requirements` section was deleted even though it
passed `validate --strict` with zero issues, and the report named only
`Purpose`.
`extractRequirementsSection` binds to the FIRST `## Requirements`, so
everything after it rides through the merge untouched: the residual-heading
veto never sees it, `findOtherSections` filters it out by title, and the
validator's own section lookup stops there too - which is why a second
section holding a `SHALL` with a scenario reads as valid and then died with
the file. The earlier round made that veto position-independent WITHIN the
section; this is the same evasion one level up.
Retirement is now refused outright for such a spec, so the archive aborts as
it did before #1302. The abort's marker hint takes the same conjunct, so it
never advises a marker that would not have helped.
2. The recovery line promised `git checkout HEAD -- <path>` unconditionally,
and the path was wrong twice over. Verified failures: an UNTRACKED spec -
the ordinary case, since an earlier `openspec archive` creates the main spec
and nobody has committed it yet - is deleted and the printed command errors,
so the file is gone for good; under a store-selected root the nominal
`openspec/specs/...` path does not exist in the caller's repo; and a
symlinked capability directory puts the file somewhere else entirely.
The line now names the path the file actually lived at, and is phrased as
the condition it really is rather than a promise archive cannot keep.
Regressions for both, plus the three fail-closed branches on the deletion
authorisation path that no test observed: a marker in unparseable YAML, and a
failing unlink. Each verified against a mutation - removing the veto, restoring
the unconditional promise, swallowing the unlink error, and honouring a marker
in broken YAML each fail their test.
Also pins the sync skill's retirement guidance by content rather than by golden
hash, since a hash proves only that it matches its source.

* docs(archive): note that retiring a capability strands an in-flight MODIFIED
A capability's main spec is the base #1482's scenario-loss check compares a
MODIFIED block against. Retire the capability and that check goes silent by
design (a missing main spec is the sister-change-in-flight case), so a change
that modifies the retired capability keeps validating clean and then refuses to
archive with "target spec does not exist". Nothing is lost - there are no
scenarios left to drop - but nothing connects the refusal back to the
retirement either, so the changeset says it up front.
Found by testing this PR against the three that merged into main today.
* fix(archive): veto retirement on any heading past the merged section
A sixth data-loss defect, from a second round of review agents. Reproduced
before fixing: a `validate --strict`-clean spec was deleted with a live SHALL
requirement in it, and the report named only "Purpose".
The cause is a mask disagreement. `extractRequirementsSection` - the function
that decides where the Requirements section ENDS - masks fenced blocks only.
`findHeadings`, which both retirement vetoes were built on, masks HTML comments
as well. So a multi-line comment holding a `## ` line terminates the section for
the merge while being invisible to the scan that had to notice it: everything
below became a tail no guard could see. The round-five guard counted `##
Requirements` headings, which the same trick skins straight past.
The veto is now asked of the tail itself - does anything `###`-shaped sit past
the boundary the merge actually chose - read with the fence-only mask, so it
answers the question whatever produced that boundary. That subsumes the
multiple-Requirements-sections case it replaces and every comment variant.
Also from this round:
- The recovery command is derived from the path that was unlinked, not rebuilt
from the capability id. On a case-insensitive filesystem the id and the real
directory differ in case, git is case-sensitive, and the printed command was
one git rejects.
- An absolute recovery path now says which checkout to run it in - for a
selected store, the file is not under the directory archive was run from.
- A declared marker refused by the tail veto says why, instead of dropping the
author who did what the docs asked back into the bare #1302 abort.
- Corrected "draws exactly these four lines" in the sync skill, a claim added
two commits ago that was false when written: the CLI checks two more.
Both regressions are mutation-verified. Reverting the veto to the narrow
multi-section count fails the comment-boundary test.
One reported finding was NOT actioned, because its premise does not hold: a
residual `###` heading INSIDE the section still counts as a requirement to the
validator, so that spec is valid and simply gets written - there is no silent
dead end there to explain.

* docs(archive): say the marker needs the schema key beside it
`.openspec.yaml` requires `schema:`, so a file holding only
`retire_capabilities: true` is not honorable metadata and the marker does
nothing. The docs and the abort hint both described adding one line, which sends
anyone creating that file from scratch into a dead end. The message did explain
itself once you were there ("schema: Invalid input: expected string, received
undefined"), but it should not need to.
Pre-existing shared behavior - `skip_specs` has the same requirement - so this
is wording, not a behavior change.
* chore: merge main (#1483) and keep both archive test suites
#1483 landed while this branch was in review. Three conflicts:
- `archive.ts`: one import line, both sides' imports kept.
- `skill-templates-parity.test.ts`: hash constants, resolved by key-union and
then regenerated from the merged source, which is the only authority once two
branches have edited the same template.
- `archive.test.ts`: the trap this repo documents. Both branches appended a
DIFFERENT describe block at the same place - `capability retirement (#1302)`
here, `non-interactive prompts (#1479)` on main - so taking either side would
have dropped 16 or 133 tests with a green suite. Both are kept.
The conflict boundary also cut the retirement describe's last two closing
braces, which `tsc --noEmit` accepted and only esbuild caught as "Unexpected
end of file". Restored by brace-balance against both parents.
Verified after: every one of main's 91 archive titles and 19 parity titles is
present, #1483's describe still holds its 16 tests, and its own non-interactive
repro still behaves as it does on main.
* fix(archive): only print a recovery command that would actually run
Both blockers from the last review.
The recovery line offered `git checkout HEAD -- <path>` for every retirement,
including ones where the file never lived under the directory archive was run
from: a selected store, or a symlinked capability directory. Git rejects an
absolute path from a different worktree however it is quoted, and an unquoted
path containing a space splits when pasted - a real store path reproduced both.
Those cases now say where the file was and leave recovery to the reader, rather
than handing them a command that cannot work. The ordinary case still gets the
command, quoted when the path needs it, via the portable quoting #1483 already
established for change names.
And `openspec/specs/specs-sync-skill/spec.md` still authorised deletion from the
four original conditions, with no mention of the tail-heading veto the CLI
gained - so the living spec permitted something the code refuses. It now carries
that condition, and a parity test pins it in the generated guidance so the two
cannot drift apart again.
Both fixes are mutation-verified: restoring the unconditional command fails the
escaped-path regression, and rewording the veto out of the template fails the
guidance test.
* fix(archive): retire only what the merge can account for
Replaces the tail-heading veto with a rule that does not read Markdown at all.
Six review rounds each found a different way to dress content so a heading scan
would miss it: a second `## Requirements` section, a `##` inside an HTML comment
ending the section early, a three-space indent, a setext underline. Every fix
was another regex approximating a parser, and every round found the next skin.
`extractRequirementsSection` has already split the file into the parts this
merge understands. So instead of asking "does anything here look like a
requirement" - a question a regex and a renderer answer differently - the guard
now asks where content ended up: anything non-blank between the `## Requirements`
header and the first requirement, or after the section ends, is content the merge
carried through without understanding, and a retirement that would delete the
file is refused. There is no second opinion to disagree with the first, because
there is no second parse.
The in-block heading guard stays, and its comment now says why: a `###` heading
that is not a requirement header is absorbed into the block above it, so it
never reaches the preamble or the tail. Folding that into the rule above needs a
parser that ends a block at any `###` heading, which belongs in the parser.
This narrows the feature: a spec carrying an authored section beyond Purpose can
no longer be retired automatically. That is deliberate. The abort names the
lines that stood in the way, and deleting a file whose contents this merge
cannot enumerate is exactly the case a person should decide.
Depends on #1490 for indented requirement headers, which are swallowed by the
block parser before any of this runs.

* fix(archive): account for the whole spec, not two slices of it
Defect eight, same class as the seven before it. The guard asked where content
landed, which was the right question, but it only read two of the five slices
`extractRequirementsSection` produces: the preamble and the tail. Content simply
moved somewhere nobody looked.
Reproduced: a hand-written migration runbook and a table written below a
requirement's scenarios live inside that requirement's `raw` - the block runs to
the next header the parser RECOGNISES - so removing the requirement deleted them,
and the report said "Its section(s) went with it: Purpose". Not silence: a false
statement the reader can act on. The same hole covered anything written above
the `## Requirements` section. And because the abort hint is gated on the same
checks, an unmarked run RECOMMENDED adding the marker that destroys it.
The audit now covers the whole file. Expected: the title, the `## Purpose`
section, the `## Requirements` header, and inside each block a requirement's own
parts - its header, its statement, its scenarios' bullets. Every other non-blank
line is reported and refuses the retirement. That folds in the `###`-heading
guard, which was a patch on this same leak using the technique the rewrite was
meant to abandon.
One reported shape is deliberately not a case: prose between `## Purpose` and
`## Requirements` IS the Purpose body, since the section runs to the next `##`,
and the warning already names Purpose as going with the file. The test says so.
Both regressions fail against the two-slice version.

* fix(specs): keep content absorbed into a removed requirement
A requirement block's `raw` runs to the next header the parser RECOGNISES, so a
heading it does not - one indented by the 0-3 spaces CommonMark allows, or a
plain `### Notes` - is absorbed into the requirement above it. Removing that
requirement deleted the absorbed content with it. Silently: nothing counted it,
so nothing warned, and the spec left behind still validated.
Reproducible on main with no marker and no capability retirement involved.
Anything from the first `#`/`##`/`###` heading after a removed block's own
header is now kept in place. `####` is excluded deliberately - a requirement's
`#### Scenario:` headings are its own and go with it.
This replaces an earlier attempt on this branch that widened every heading
pattern in both parsers to accept indentation. That was wrong twice over. It
reclassified content, so a spec that was valid became invalid - commented-out
and indented examples started parsing as real requirements, taking `list` from
1 requirement to 3. And it did not even fix the bug: moving the line out of the
block only meant the reconstruction dropped it at a different step, since
`rebuilt` is assembled from `before + header + kept blocks + after` and anything
skipped is simply gone.
So nothing is reclassified now. An indented heading is still not a requirement,
exactly as before; it just survives its neighbour's removal, which is all this
ever needed to do. The repo's own corpus produces byte-identical `list`,
`validate --specs --strict` and `validate --changes --strict` output.
Four regressions, each mutation-verified: removing the salvage fails the three
absorbed-content cases, and counting `####` as a boundary fails the scenario
case.

* fix(specs): keep notes absorbed into a modified or removed requirement
A slow audit of the previous commit found the fix covered one of three paths.
A requirement block absorbs anything below it that the parser does not read as
a new header - a note indented by the 0-3 spaces CommonMark allows, say - so
that content rides inside the block. The previous commit salvaged it when the
requirement was REMOVED and missed MODIFIED entirely: that path rebuilds the
block from the delta, which never carried the note, so it was dropped exactly as
before. Verified against the real CLI: main loses it on both paths.
RENAMED was the opposite trap. It rewrites the original block's header line in
place, so the note is already there - but it also deletes the original key from
the block map, which made the requirement look REMOVED to the salvage and
produced a duplicate. Tracking which operation applied is therefore not reliable
at this point in the merge, so the salvage now asks the assembled result
instead: re-insert a note only when nothing else in the rebuilt section already
carries it. That is correct for all three paths by construction.
Salvaged content also keeps its position now, next to the requirement it was
written beside, rather than being appended at the end of the section.
Six regressions, three of them mutation-verified against this logic: never
re-inserting fails four, always re-inserting duplicates on rename, and appending
at the end loses the position.

* fix(specs): decide salvage by identity, not by matching text
Another audit pass, another defect in my own fix.
Deciding whether a note survived by searching the rebuilt section for its text
is wrong when two requirements carry the same note: the first copy is found,
and the second is dropped. Reproduced - two removed requirements each followed
by an identical `### Notes`, one note destroyed.
Survival is a question about the block, not about text. An untouched block is
the same object the parser produced and still carries its note; a replaced one
is a different object and does not. The RENAMED path previously blurred that by
copying the whole raw, so it now carries only the requirement's own lines and
the salvage puts the note back like every other path. With every replacement
uniformly lacking the tail, `replacement !== block` decides it exactly, and no
text is compared at all.
Four properties, each mutation-verified: matching text instead of identity
loses the duplicate note, always re-inserting doubles an untouched block's note,
letting RENAMED keep the tail doubles it on rename, and counting `####` as a
boundary severs a requirement from its scenarios.

* fix(specs): warn when a note absorbed into a requirement will be deleted
An adversarial review found the previous approach was worse than the bug.
Salvaging the "foreign tail" out of a requirement block relied on a positional
rule: everything after the first heading-shaped line is not the requirement's.
That is not true. A `# comment` inside a scenario bullet, or a markdown example,
matches the same shape - and on MODIFIED the old text was then spliced back in
after the new, so the spec asserted both. The validator called the result valid,
and re-applying the same delta grew the file every time. Reproduced end to end.
It also turned a working archive into a hard abort: preserving an unindented
`### Notes` made the rebuilt spec fail validation as a scenario-less
requirement, so changes that archived cleanly on main stopped archiving, with an
error that never mentioned the note.
Measured before choosing: 3 of 742 requirement blocks in this repo contain a
heading-shaped line, and the repro shows those are false positives. Trading a
rare silent deletion for silent corruption on the most common operation is a bad
trade.
So the merge is left exactly as it was - byte-identical output, verified against
main - and the loss is reported instead. That fixes the part of the bug that
actually hurt: it was silent. A wrong warning costs a line of output; acting on
a wrong answer rewrites the spec.
Eight tests. Dropping the warning fails three; ignoring the fence mask fails
one - the fence case the previous version left unpinned.

* fix(archive): scope a scenario's bullets, and stop refusing ordinary prose
Defect nine, plus the over-refusal it exposed.
Every bullet counted as a scenario's own, anywhere in the block. So an
operational note bulleted below the last scenario - "IMPORTANT: escrow keys
live in the legacy vault" - was deleted with the file, on a spec that passes
`validate --strict`, and the report named only "Purpose". A scenario's bullets
run unbroken beneath its header; a blank line after them ends the run, and
bullets past that point are the author's own note.
Measuring the guard against this repo's 36 specs then showed the opposite
failure was already there: 7 of them could never be retired, almost entirely
because every fenced line inside a requirement was treated as foreign. A code
example inside a scenario is that requirement's own content - a
`### Requirement:` inside a fence is not a heading to any reader - so fenced
lines are now accounted for, as are numbered lists and a statement that opens
with inline code.
One ambiguity is left deliberately unresolved: a scenario whose bullets are
split by a blank line reads exactly like a note bulleted below it, and no
line-based rule separates them. Those specs are REFUSED, never deleted. The
abort quotes the lines, and the author moves them or removes the file by hand.
Refusing costs a message; the alternative costs the file.
Two regressions: the bulleted note must refuse, and a requirement using a
numbered list, a fenced example and an inline-code statement must still retire.

* fix(archive): a section is not only an ATX heading
Defect nine, from a deep adversarial pass, and it is the same species as the
eight before it: the guard decided what a section IS by one syntax while a
reader recognises three.
Once `## Purpose` was seen, every later line in the pre-requirements slice was
accepted as its body until the next ATX `##`. But a setext underline turns the
line above it into a heading, and raw HTML says so outright - a reader sees a
sibling of `## Purpose`, not more of it. So a whole authored section could sit
between Purpose and Requirements, pass `validate --specs --strict`, and be
deleted with the file while the report said only "Purpose". On main the same
archive aborts and loses nothing.
Reproduced with a `Data Migration Notes` section underlined with dashes: the
capability retired, the notes gone, unnamed. Now refused, with the lines quoted.
Two path defects from the same review, one fix: the reported path was rebuilt
from the capability id, so on a case-insensitive filesystem it differed in case
from the file actually unlinked and git rejected the printed command; and a
capability directory symlinked to a sibling deleted one spec while naming
another. `retireSpec` now always returns the path it unlinked, and archive
reports that. Whether to print a command at all is decided against the REAL
repo root, so a symlink that stays inside the repo still gets a working command
and only a path that genuinely leaves it falls back to prose.
Also pins `!skipValidation` in isolation. The existing --no-validate test passed
for the wrong reason - its fixture was blocked by the content guard - so the
conjunct itself was unpinned.
Four regressions, all mutation-verified.

* fix(archive): close remaining capability retirement gaps
* fix(archive): close final transaction safety gaps
* fix(archive): close retirement race windows
* fix(archive): preserve retirement authorization
* fix(archive): verify complete fallback copies
* fix(archive): preserve transactional safety
Reject structurally ambiguous or symlinked inputs before mutation, serialize archive claims safely, and preserve permissions during verified fallback moves.
Keep retired specs as inode-preserving backups until the archive commits, restore them on rollback, and retain any backup changed concurrently instead of deleting user data.
* fix(archive): preserve replaced claims on Windows
Add a per-claim nonce and verify stable claim contents before unlinking because Windows file IDs may not distinguish a replacement lock entry.
* test(archive): respect Windows deferred deletion
Skip the POSIX unlink-and-recreate claim simulation on Windows, where deletion of an open file remains pending until the original handle closes.
* test(archive): align symlink fixtures with path boundaries
