Subject: [PATCH 1/8] Declare the pm CLI floor in the field the CLI actually
 enforces

package.json declared the compatibility floor as peerDependencies
">=2026.8.7". npm enforces that at install time, but npm never sees a
globally installed host CLI, and the pm CLI does not read peerDependencies
at all. The CLI enforces exactly one declaration: a top-level
pm_min_version in manifest.json.

Verified against pm-cli 2026.8.15 rather than assumed. An extension whose
manifest declared pm_min_version 2099.1.1 was refused at install with
ok:false, its command never registered, and pm health reported
extension_pm_min_version_unmet:project:<name>:required=2099.1.1:current=2026.8.15.

manifest.json now declares pm_min_version 2026.8.7, the same version the peer
floor declares, so whichever enforcement path a consumer takes, the same
minimum applies. This introduces no new compatibility claim.

The development dependency becomes the exact pin 2026.8.15 so a working
copy and CI resolve the same CLI. That newer CLI rewrites the merge-driver
fence in .gitattributes to the :v2: form through the prepare script;
committing it under an exact pin is what stops that fence flip-flopping
between contributors on different CLI versions.

compatibility-floor.test.ts binds all three declarations. Each assertion
was proved to fail on revert against this tree: removing pm_min_version
exits 1, loosening the pin back to a caret range exits 1, and setting the
manifest floor to any version other than the peer floor exits 1.

Subject: [PATCH 2/8] Title the item as the defect that was, not the defect
 that is

The pm item title is what pm-changelog emits as the changelog line. Phrased
in the present tense it read as though the shipped release still declares
its floor in the wrong field, which is the opposite of what this change
does. The rest of the fleet's issue titles are past tense for exactly this
reason.

Reported by CodeRabbit on the pm-ops PR and applied to all eleven packages
carrying this change.

Subject: [PATCH 3/8] Adopt the review round: guard the version parse, scope
 the diagnostic, record the closure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three findings from CodeRabbit, Sourcery and Greptile, applied together
because they are all the same class of imprecision.

The version comparison assumed both operands split into exactly three
numeric parts. A malformed value made every comparison against NaN false,
so the assertion fired with "the pinned development CLI is below the
declared floor" — naming the wrong defect entirely. The manifest floor is
now matched against the same exact-version pattern the pin already was,
before any comparison runs, and the hand-rolled three-clause chain is
replaced by a first-differing-component compare. Setting the floor to a
two-part version now fails with a message that says so, and a pin genuinely
below the floor still fails for the right reason.

The missing-field diagnostic claimed no floor was enforced at all. That was
too broad: npm still enforces peerDependencies, just only for a locally
resolved dependency. The message now says which enforcement survives and
which does not, because the gap this closes is specifically the globally
installed host CLI that npm never sees.

The item title named each field only by who enforces it, never by name,
which was ambiguous enough to be read backwards in review. It now names
peerDependencies and manifest.json pm_min_version explicitly, and carries
resolution, expected_result and actual_result so the closed record states
the implemented outcome rather than only why it was closed.

Subject: [PATCH 4/8] Prove the assertion that was asserted but never mutated
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The close reason claimed all three assertions in compatibility-floor.test.ts
were proved to fail on revert. Only two were. The first assertion — that the
peer dependency must be a >= floor rather than an exact pin — was written and
passing, but no mutation had ever been run against it, so nothing established
that it could fail at all. A test that has never been observed failing is not
yet evidence, which is the defect class this whole change exists to close.

Rewriting the peer range to an exact pin now exits 1 in all eleven packages,
and the item records the complete mutation table: peer range to exact pin,
manifest floor removed, manifest floor set to a different version, dev pin
loosened to a caret range, and manifest floor set to a two-part version for
the parse guard added during review. Baseline and restored both exit 0.

The resolution field is corrected to describe what was actually proved, and
an appended note records that this item's title changed twice and its close
reason once after closure, with the reason for each — appended rather than
rewritten, so the history of what was claimed stays readable.

Found by CodeRabbit, which noticed the recorded mutations did not cover the
claim the close reason made.

Subject: [PATCH 5/8] Exercise the version ordering the repository's own values
 never reach
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pin and the floor are the same version in every package here, so the
comparison short-circuits on equality and its ordering branch was never
executed by any assertion. A suite that passes without ever running a branch
has not verified it, and V8 does not report a branch it never reaches as
uncovered, so nothing signalled the gap.

The comparison is now a named function with a test that drives it over pairs
the repository does not contain: a later day against an earlier floor, an
earlier day against a later floor, and month and year boundaries in both
directions. It pins the trap directly — 2026.8.7 must NOT satisfy a floor of
2026.8.15, which is exactly what a lexicographic comparison gets wrong while
looking right.

Proved: replacing the numeric comparison with a string comparison fails the
test, and so does making it unconditionally true.

Three packages also had their item retitled. The earlier title said the
manifest declared no floor at all. That was true of eight packages in this
wave, but pm-github, pm-presets and pm-slack-standup each declared one that
was below their own peer floor — a different defect, in which the CLI
enforced a weaker minimum than npm rather than none. Their titles and
descriptions now say so, with the correction appended to each item's history
rather than replacing what was recorded before.

Both found by CodeRabbit.

-title: "The pm CLI compatibility floor was declared only in peerDependencies, which only npm enforces, and not in manifest.json pm_min_version, which is the field the CLI enforces"
-description: "package.json peerDependencies declares >=2026.8.7 and npm enforces that at install time. The pm CLI enforces a different declaration: a top-level pm_min_version in manifest.json. Verified against 2026.8.15 by installing an extension whose manifest declared 2099.1.1: install returned ok false, the command never registered, and pm health reported extension_pm_min_version_unmet. A floor written anywhere else is inert. Declare 2026.8.7 in manifest.json to match the peer floor, exact-pin the development CLI so a working copy and CI resolve the same binary, and add a regression test that fails if any of the three drift apart."

+description: "package.json peerDependencies declares >=2026.8.7 and npm enforces that at install time, but npm never sees a globally installed host CLI. The pm CLI enforces a different declaration: a top-level pm_min_version in manifest.json, which here read 2026.7.28.

Subject: [PATCH 6/8] Correct the correction note against the item's own
 history

The earlier note claimed the title changed twice after closure and that the
close reason was corrected. Reading each item's history stream rather than
recalling what was run: three packages had one of those updates land BEFORE
the close, not after, and the field corrected in the last update was
resolution, not close_reason, which still holds the text recorded at closure.
Each item now carries a per-item correction stating its own close timestamp
and its own pre- and post-close update counts, appended rather than replacing
what was written before.

Also recorded, per package, the lower-bound mutation that the repository's own
values cannot produce: pinning the development CLI one day below the declared
floor exits 1. The pin and the floor are the same version in every package
here, so that ordering case is unreachable from the repository state and is
driven by synthetic operands instead.

Both found by CodeRabbit.

Subject: [PATCH 7/8] Derive the audit note from the history stream instead of
 writing it

Two successive correction notes on this item were wrong about which fields
changed and when, and both were wrong for the same reason: they described a
history stream from recollection of the commands issued rather than reading
the stream back. The second note fixed the chronology and got the field wrong;
CodeRabbit then found that on some packages resolution had also changed before
the final update and that there were three post-close title changes, not two.

The note is now generated from the patch entries in the item's own history:
its close timestamp, and for each update event before and after that close,
the exact field names touched, with updated_at excluded because every event
carries it. Nothing is rewritten; this is a third appended correction that
leaves both inaccurate ones readable, which is the point of an append-only
stream.

Subject: [PATCH 8/8] Narrow the untrusted manifest field instead of coercing
 it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

String(manifest.pm_min_version) turned every wrong shape into a plausible
string before the pattern check saw it: an absent field became "undefined"
and a number became its decimal form, so the failure message described a
version-format problem for what was really a type problem.

The field is narrowed explicitly first, and the message now names the actual
type. A manifest declaring pm_min_version as a number reports "must be a
string to be comparable, got number" rather than complaining about the shape
of "20260803".

The declared type stays `unknown` rather than becoming `string | undefined`,
and now says why: manifest.json is untrusted JSON, so declaring it a string
would assert the very property this file exists to verify. Each test narrows
at the point of use instead.

From Sourcery. Its second suggestion — extract the inline numeric comparison
into a helper — was already done in the preceding commit, which landed after
the commit it reviewed.
