Implements #1683, which carries the full rationale and numbers the design decisions I–X so they can be argued with individually. This PR is the whole thing; the issue is where to push back on any single decision.

Why

This started as a CI problem that turned out not to have a CI solution. We wanted a pipeline check enforcing that changes actually get archived, because without one specs/ silently drifts from shipped reality — someone merges, forgets the archive step, and the living specs quietly stop describing the system. But that property is violated by design for the entire life of an open PR: the change sits in changes/, unarchived, precisely because it isn't finished. So the check is red as its resting state, on every PR, from first commit to last.

Every way around that is bad: a permanently-red pipeline everyone learns to ignore (which also masks real failures); a blocking manual job, which is the same permanent-red problem wearing a different hat and has nothing to trigger on anyway; a bot maintaining a review comment as a blocking condition, which is what we do today and moves enforcement outside CI into something that has to model the lifecycle itself; or archiving early inside the PR, which review feedback then invalidates with no unarchive to back it out.

The cause is that archive does two unrelated jobs in one command — a state transition (declaring a change shipped) and a text merge (folding deltas into specs/) — and encoding the transition as a directory move welds the merge to a single moment that, on a reviewed workflow, doesn't exist.

The fix is to make the check conditional on the change's own claim: not "is everything archived?" but "does anything claiming to be shipped still have unfolded deltas?" A proposed change passes for free, so green is the resting state and red means a real mistake. That requires a change to declare its state as data rather than by directory position. #1683 has the full argument.

What this adds

# openspec/config.yaml
lifecycle: status    # default remains `archive`
  • status: proposed | shipped in a change's .openspec.yaml; new changes are born proposed
  • openspec sync — folds every shipped change's deltas into specs/, idempotently
  • openspec sync --check — exits 1 if any shipped change has unfolded deltas; the same command gates pre-commit, pre-push and CI
  • openspec ship <change> — sets the field and folds in one diff
  • openspec list — lifecycle column and --status <state> filter
  • openspec archive — refuses under status mode; openspec ship refuses under archive mode, so the two models stay disjoint
  • changes stored sharded by immutable creation date (changes/YYYY/MM/DD-<name>/), enumerated by one shared discovery that reads both layouts
  • openspec migrate — converts between modes in either direction, moving only bookkeeping

The two design points I'd most like reviewed

Folded-ness is decided by regeneration, not bookkeeping (decision IV). A change is folded when re-applying its delta to the current spec produces byte-identical output — no lockfile, no hash sidecar, nothing to corrupt. --check and the write path therefore run the same code, differing only in whether the rebuilt bytes get written. That's a direct response to #1112, where validate accepted deltas archive then refused: a checker that reimplements the doer eventually disagrees with it.

The gate is a tree predicate, not a timing condition (decision V). shipped ⇒ folded is a pure function of files on disk, evaluable on any tree by anyone. "Did archive run at the right moment?" cannot be evaluated mid-PR, which is exactly when the invariant is supposed to be violated.

The layout decision is the one I expect to lose

Decision VIII in the issue, and I'll say it here too: #1367 answers the layout question better than this PR does. Its walkForLeaves decides change-vs-container by a leaf marker rather than a naming convention parsed out of regexes, and user-chosen domains carry meaning a calendar cannot. If both landed, a domain named 2026 would be ambiguous with a year shard.

If you'd prefer, I'll strip the sharding and migration from this PR and rebase the mode onto #1367's discovery — decisions I–VII don't depend on which layout wins, only on nothing moving. It's included here because the issue asks to show the whole design working end to end, and because the migration story needs some layout to migrate into.

Cutting the other way, and worth flagging for #1367's author: a large share of that PR is the archive move interacting with domains — buildArchivePath mirroring the domain tree into a second tree, findAllArchivedChangeIds enumerating it, assertProspectivePathContained walking a not-yet-existing destination for symlink escapes, archive reserved as a domain name because two trees share a namespace, plus collision handling and two archive workflow templates. Under this mode none of that has anything to do. An observation, not a precondition.

Compatibility

Fully opt-in and inert by default. No lifecycle key — or an unreadable or unrecognized value — resolves to archive and behaves exactly as before. Under archive mode sync reports there's nothing to gate and exits 0, ship refuses and points at openspec archive, list renders no lifecycle column, archive is untouched, and discovery returns exactly what it returned before for a flat tree.

One cosmetic change does reach archive mode: the generated spec skeleton's Purpose line no longer says "created by archiving", since a fold can now happen without one. That collides textually with #1671 / #1670, which add placeholder detection keyed on that string — whichever lands second should reconcile the wording, and I'm happy to be the one who does.

Verification

  • tsc --noEmit clean; full suite 4000 tests passing
  • 4 pre-existing failures on this machine (view-store-resolution ×2, config-profile, workflow-instructions-skipped) reproduce identically on unmodified main at 2826b88 — environmental, not from this change
  • openspec validate add-lifecycle-status-mode --strict passes on this PR's own dogfooded change
  • End-to-end demo with real backdated git history, live hooks and CI: https://github.com/ixxie/openspec-status-demo — five months of the legacy archive workflow, one openspec migrate commit, then the new workflow, plus a demonstration PR where a ship-without-fold commit turns CI red with the remedy named and one openspec sync commit turns it green. DESIGN.md explains the design from first principles.

Open questions

  1. Strip the layout work now and wait on feat: support multi-level change domains and sibling archives #1367, or keep it as a self-contained prototype and reconcile later?
  2. lifecycle as a top-level config key, or nested under operations: pending Proposal: decide where workflow phases (apply/archive/sync) are configured — schema.yaml, config.yaml, or both #1456?
  3. Confusing terminology for new users: "delta spec" vs "main spec", and "sync" at archive time creates rather than reconciles #1647 argues "sync" is the wrong verb — that at archive time it creates rather than reconciles. If that leads to a rename (promote, graduate), this should adopt it; the naming isn't load-bearing, the decoupling is. Happy to rename before merge.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟠 High · up to a11ff

The new lifecycle mode can silently miss changes during gating, resolve the wrong change when flat and sharded layouts overlap, and potentially discard archived data during migration if the archive is unreadable; its JSON failure behavior and platform-dependent tests also need correction. The PR should not merge until these concrete correctness and data-safety issues are addressed.

Filter before reading task and timestamp data.

When --status is set, Lines 149-151 process every change before Lines 152-155 reject nonmatching changes. Read and filter lifecycle immediately after building changePath. Then calculate task progress and lastModified only for matching changes. This avoids recursive filesystem walks for excluded changes.

Keep --json failures machine-readable.

Lines 469 and 487 call failWithError(error) without json.enabled. Therefore, openspec sync --json and openspec ship --json emit terminal error output instead of the required JSON error document. Pass the JSON mode to failWithError in both handlers. Return after failWithError because it already sets process.exitCode; do not force process.exit(1).

Proposed fix
     } catch (error) {
-      failWithError(error);
-      process.exit(1);

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Fail closed when change discovery is incomplete.

readChangeMetadata() returning null skips a change directory. ShipCommand identifies this result as a missing .openspec.yaml at Lines 272-276. Therefore, sync --check can report clean when a status-mode change has no lifecycle metadata.

The catch around fs.readdir() also converts permission and I/O errors into an empty change list. This can hide shipped changes and make the gate pass.

Report these cases as conflicts, or fail the command. Only treat an absent changes/ directory as empty if that layout is intentionally valid.

Restore process.exitCode after the test.

Line 241 changes process-wide state. The finally block restores console.log and the working directory, but it does not restore the original exit code. A later test or the test process can observe the stale value 1.

Proposed fix
   it('refuses in JSON mode with a diagnostic and leaves the change in place', async () => {
     const cwd = process.cwd();
+    const originalExitCode = process.exitCode;
+    let exitCode: number | string | undefined;

     } finally {
       console.log = originalLog;
       process.chdir(cwd);

Derive the fallback date the same way change creation does.

new Date().toISOString().slice(0, 10) yields a UTC date. createChange in src/utils/change-utils.ts stamps created with formatLocalDate(). Near midnight the two conventions disagree by one day, so a migrated change without readable created metadata shards under a different date than a change created at the same moment. Reuse formatLocalDate() here.

Second review round addressed in c2ebd50.

Fixed — real findings:

  • A refused change id stays refused. show and validate fell back to path.join(changesPath, id) when resolveChangeDir returned null, re-admitting exactly the ids the resolver exists to reject — so show 2026 could operate on a year shard and validate archive on the archive directory. Good catch; the fallback also made the local traversal guard load-bearing, and it's now retired since the resolver subsumes it.
  • migrate resolves its root instead of assuming the process cwd. Run from a subdirectory it previously found no changes and then failed inside setLifecycle with a raw ENOENT.
  • UTC vs local fallback date. migrate stamped new Date().toISOString(); createChange stamps formatLocalDate(). Near midnight a migrated change sharded a day away from one created at the same moment. Both use formatLocalDate now.
  • list filter test claimed to cover the empty-match message without asserting it.

Deferred, deliberately: --store on migrate. The flag's surface is mirrored in STORE_SELECTION_GUIDANCE, which is snapshotted into committed skills/ files and guarded by two parity tests — so adding it cascades a large diff unrelated to this proposal. Happy to do it as a follow-up; the root-resolution half of that finding is fixed here.

Not applied, with reasons:

  • "Report a change with no .openspec.yaml as a conflict." Not gating pre-adoption changes is the documented design (see the Migration section of the change's design note): a project flips one config line and its existing changes are simply not gated until ship stamps them. Reporting them as conflicts would make adoption start red.
  • "Restore process.exitCode after the JSON archive-refusal test." The enclosing describe already captures and restores it in afterEach (test/core/sync.test.ts:199, :217).
  • Three findings from this round were already fixed at the reviewed head — the --json error contract on sync/ship, the spec's claim that ship no-ops under archive mode, and the readdir catch swallowing I/O errors (that path now goes through discoverChanges, which rethrows non-ENOENT at depth 0). They landed in 1a90b2e and 5adbe6e.

Separately, I replaced the hand-waved "negligible" performance claim in #1683 with measured numbers, including the case I'd missed: when many shipped changes pile onto a single capability the gate is quadratic (400 changes on one capability → 69 KB spec → 853 ms), because each rebuild re-parses a spec that grows with history. Fixing the asymptote properly needs either per-capability ordering (out of scope, that's parallel-merge territory) or a pre-filter with its own correctness proof, so it's documented rather than papered over. Scoping by git diff is the one fix I'd argue against — it reintroduces a VCS dependency into a predicate whose value is being VCS-independent.

Keep each discovered directory paired with its ID.

discoverChanges can return the same bare ID from flat and sharded directories. changes preserves both entries, but dirs overwrites one directory by ID. JSON and long output can then report both entries from the last directory and hide the other directory. Iterate DiscoveredChange entries directly, or reject duplicate IDs consistently with resolveChangeDir.

Third round addressed in a11ffb5 — thanks, these were the best batch yet. All six were real, and two of them were fail-open holes in exactly the property this proposal claims.

  • Shard errors were swallowed below the root. walkShard only rethrew at depth 0, so an unreadable year or month directory returned an incomplete result and sync --check could report clean: true without ever inspecting a shipped change. Only ENOENT returns empty now, at every depth. An unreadable month shard hides shipped changes exactly as effectively as an unreadable root — that distinction was never defensible.
  • A flat hit masked a sharded twin. With both changes/foo/ and changes/YYYY/MM/DD-foo/, resolution returned the flat one while list showed both, so a command acted on a change the listing didn't name. It enumerates first and merges now. Worth recording why the flat lookup can't simply be deleted: readdir dirents don't follow symlinks, so a change directory linked into changes/ is invisible to the walk — stat is what makes allows a linked change directory as its own trust root pass. Merging keeps both properties.
  • migrate skipped the stamp when a change didn't move, leaving status on a proposed change under --to archive — which contradicts this PR's own lifecycle-migration spec ("the status key SHALL be removed"), and a later forward migration would have read the stale key as authoritative. Renaming and stamping are separate obligations now.
  • createChange read the clock twice, so a change created across local midnight could be dated a day off its own shard path.
  • The deprecated noun-form list swallowed discovery errors and collapsed its id→directory mapping through a Map, which would report two same-id directories as one.

Three regression tests added: an unreadable month shard propagates, a flat/sharded id collision is refused, and a non-moving change still gets stamped.

Suite is 3997 passing. The remaining failures on this machine are the four that reproduce on unmodified main at 2826b88, plus intermittent 10s timeouts in the CLI-spawning suites (show.test.ts, spec.test.ts) — I verified those by stashing this branch's changes and re-running show.test.ts on the untouched tree, where it fails identically. Different victim each run; they take 7-8s when they pass.

Fourth round addressed in fbb93ac. All four were real; two of them are the same class of bug I'd already been caught on twice, in places I hadn't thought to look.

  • Creation and resolution disagreed on the addressable namespace. validateChangeName accepted archive and bare four-digit years — both pass the kebab grammar (isKebabId('2026') === true), and both name directories the layout owns. So openspec new change 2026 created a change that resolveChangeDir would then refuse to address, forever. Creation now shares the resolver's policy through an exported isReservedChangeId, which is the point: the two can't drift if there's only one of them.
  • MigrateCommand.dirs() swallowed every readdir error, and this one had teeth — its result gates fs.rm(archiveDir, { recursive: true }). An unreadable archive/ would have been read as empty and then removed. Only ENOENT counts as empty now. Third instance of this class in this PR, which is a fair thing to have kept pushing on.
  • A compatibility symlink read as ambiguity. After last round's merge fix, changes/foo → changes/2026/03/15-foo produced two matches by path string and reported a perfectly healthy tree as ambiguous. Comparing physical identity via realpath fixes it, and that's the semantically right comparison for a set that exists to answer "is this one change or two?"
  • The chmod test was wrong for your CI. You're right that permissions don't constrain root and don't exist on Windows — that test would have failed your windows-pwsh leg. It injects EACCES through a readdir spy now, which also tests the actual property (how the walk reacts) rather than how the OS produces the condition.

Two regression tests added (symlink alias resolves to one change; reserved ids refused at creation), and the change-layout-discovery spec gained a scenario for the creation rule so the capability text matches the behaviour.

Suite is 4001 passing. Remaining failures are the four that reproduce on unmodified main at 2826b88, plus one intermittent 10s timeout in spec.test.ts — a different test in that file each run, which is the signature of the CLI-spawn flake rather than anything in this branch.

Every surface that enumerated changes did its own readdir of
openspec/changes/, and every surface that resolved a change id did its
own path join. That was fine while a change was always exactly one
directory deep, and it is the reason adding any other layout would
otherwise have to be repeated a dozen times.

This introduces a single discovery module and routes the enumeration and
resolution surfaces through it: show, validate, status, instructions,
shell completions, the dashboard view, and the path-derived name helpers
in the JSON converter and the validator.

Behaviour is unchanged for the flat layout every project uses today. The
module also fixes two things the scattered copies got wrong: an id
containing a separator or dot segment now resolves to nothing rather
than being joined into a path, and a directory the walk cannot read
propagates its error instead of being reported as an empty result.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`archive` does two unrelated jobs in one command: a state transition
(declaring a change shipped) and a text merge (folding deltas into
specs/). Encoding the transition as a directory move welds the merge to
one moment in the review lifecycle, and on a team with code review that
moment does not exist — which is why "is everything archived?" cannot be
enforced in CI without being red for the whole life of every PR.

Under the opt-in `lifecycle: status` mode a change records its own state
in `.openspec.yaml` as `status: proposed | shipped` and never moves:

  openspec sync           fold every shipped change's deltas into specs/
  openspec sync --check   exit 1 if a shipped change has unfolded deltas
  openspec ship <change>  declare shipped and fold, as one diff

The gate becomes a predicate over the working tree — shipped implies
folded — which a proposed change satisfies for free, so green is the
resting state and red means a real mistake. Folded-ness is decided by
regeneration rather than bookkeeping: a change is in sync when
re-applying its delta produces byte-identical output, so `--check` and
the write path run the same code and cannot drift apart the way Fission-AI#1112's
validate and archive did.

`openspec list` gains a lifecycle column and a `--status` filter, and
`openspec archive` refuses under status mode while `openspec ship`
refuses under archive mode, so the two models can never both claim a
change. Projects that do not set `lifecycle` resolve to `archive` and
are entirely unaffected; the one visible change there is that a
generated spec skeleton no longer says it was created by archiving,
since a fold can now happen without one.

…igrate`

If nothing ever moves, changes/ accumulates, so under `lifecycle: status`
a change is stored at changes/YYYY/MM/DD-<name>/ — sharded by a date
assigned at birth. Creation date specifically, because it can never
change; sharding by shipped date would smuggle the move back in.

`openspec migrate` converts a project between the two modes in either
direction, moving only bookkeeping. Neither direction touches spec text:
archive-mode specs/ is folded shipped reality, which is exactly what
status mode maintains, so reversal is a pure relayout. An experiment
users can leave is an experiment that can actually be removed.

The forward direction refuses before moving anything when the result
would contain two changes sharing a bare id — the case a legacy name
reused across archive eras produces, which the archive date prefix
permits — and it writes the config line last so an interrupted run
resumes. The reverse direction refuses while any shipped change has
unfolded deltas, reusing the gate's own verdict rather than
reimplementing it, since the archive layout asserts folds that must
already exist.

This commit also registers sync, ship and migrate on the CLI and in the
completion registry.

Note for review: this layout is the part of the proposal I expect to
lose. Fission-AI#1367 answers the same question with user-chosen domains found by
a leaf marker rather than a date convention parsed out of regexes, which
is the better mechanism — and if both landed, a domain named 2026 would
be ambiguous with a year shard. The mode above does not depend on which
layout wins, only on nothing moving.

The repo tracks its own features as OpenSpec changes, so this one is
tracked as one: proposal, design note, tasks, and three capability specs
covering the mode, the layout discovery, and the migration.

The design note records the reasoning that is not visible in the diff —
why the state set is closed at two, why folded-ness is decided by
regeneration rather than bookkeeping, why archive and status refuse each
other, and why the layout decision should defer to Fission-AI#1367 if that lands.

Rebased onto 7da3f34 and squashed the history into four logical commits.

The branch had grown sixteen commits, nine of which fixed things introduced earlier in the same branch across four review rounds — accurate as a record of how it was built, but not something worth asking a reviewer to read. It is now:

  1. refactor(changes) — one layout-agnostic discovery module, with every enumeration and resolution surface routed through it. Behaviour-neutral for the flat layout every project uses today.
  2. feat(lifecycle) — the mode itself: the config flag, the status field, sync / sync --check / ship, the list surface, and the mutual refusal between archive and status.
  3. feat(lifecycle) — creation-date sharding and bidirectional migrate, plus the CLI and completion wiring. Carries a note in its message that this is the decision I expect to lose to feat: support multi-level change domains and sibling archives #1367.
  4. docs(lifecycle) — the dogfooded proposal, design note and capability specs, plus the changeset.

Each commit typechecks on its own, and the final tree is byte-identical to what you reviewed at fbb93ac — I verified that with git diff before pushing.

One conflict came out of the rebase, in change-utils.ts: #1638's skip_specs emission landed on the same metadata object this branch touches. Both sides belong, so the resolution keeps upstream's skip_specs alongside this branch's reuse of the creation date and the born-proposed status.

Suite is 4108 passing against the new base. The failures on my machine are now five rather than four — renders blocking lines safely and boundedly from #1699 joined the list, and I confirmed it fails identically on pristine upstream/main; it asserts no raw ANSI escapes reach the output, and chalk colours the block in this environment. The other four are the same pre-existing ones.

Apologies for the noise the force-push causes on the earlier inline threads — the findings behind them are all fixed, and my replies summarising each round are still in the conversation above.
