 ## [Unreleased]
 
+### Added
+- Add `archive` support for compacting closed tickets while preserving their
+  metadata for dependency, relationship, listing, and display commands
+
+### Fixed
+- Keep routine commands responsive on large stores by reading archived ticket
+  metadata from one compact index instead of opening every closed ticket
+- Prevent `closed` from exiting with SIGPIPE when more than 100 ticket files
+  are present
+
 ### Changed
 - Extracted `edit`, `ls`, `query`, and `migrate-beads` commands to plugins (ticket-extras)

-- ticket-ls 1.0.0: List tickets with optional filters (extracted from core); `ticket-list` symlink for alias
-- ticket-query 1.0.0: Output tickets as JSON, optionally filtered with jq (extracted from core)
+- ticket-edit 1.0.1: Resolve archived IDs and require reopening before edits
+- ticket-ls 1.1.0: List active and indexed archived tickets without reopening

+## Archiving closed tickets
+
+Large ticket stores can keep routine graph commands fast by moving closed
+tickets into the indexed archive:
+
+```bash
+tk archive                 # archive every closed ticket
+tk archive abc-1234        # archive selected closed tickets
+tk archive --reindex       # rebuild metadata after resolving archive merges
+```
+
+Archived Markdown files remain available to `show`, `closed`, `ls`, `query`,
+partial-ID lookup, and dependency graph commands. Reopening an archived ticket
+moves it back into the active directory. Relationship edits require reopening
+first so the compact archive index cannot become stale.
+
 ## Plugins
 
 Executables named `tk-<cmd>` or `ticket-<cmd>` in your PATH are invoked automatically. This allows you to add custom commands or override built-in ones.

+Feature: Ticket Archive
+  As a user with a large ticket store
+  I want to archive closed tickets
+  So that routine commands stay fast without losing history
+
+  Background:
+    Given a clean tickets directory
+
+  Scenario: Archive all closed tickets
+    Given a ticket exists with ID "done-0001" and title "Done ticket"
+    And ticket "done-0001" has status "closed"
+    And a ticket exists with ID "open-0001" and title "Open ticket"
+    When I run "ticket archive"
+    Then the command should succeed
+    And the output should contain "Archived 1 ticket(s)"
+    And ticket "done-0001" should be archived
+    And ticket "open-0001" should remain active
+
+  Scenario: Archived dependency remains resolved
+    Given a ticket exists with ID "ready-0001" and title "Ready ticket"
+    And a ticket exists with ID "done-0001" and title "Done dependency"
+    And ticket "ready-0001" depends on "done-0001"
+    And ticket "done-0001" has status "closed"
+    When I run "ticket archive done-0001"
+    And I run "ticket ready"
+    Then the command should succeed
+    And the output should contain "ready-0001"
+
+  Scenario: Show archived ticket with relationships
+    Given a ticket exists with ID "done-0001" and title "Done ticket"
+    And a ticket exists with ID "open-0001" and title "Open child" with parent "done-0001"
+    And ticket "done-0001" has status "closed"
+    When I run "ticket archive done-0001"
+    And I run "ticket show done-0001"
+    Then the command should succeed
+    And the output should contain "# Done ticket"
+    And the output should contain "open-0001 [open] Open child"
+
+  Scenario: Reopen archived ticket restores it to active tickets
+    Given a ticket exists with ID "done-0001" and title "Done ticket"
+    And ticket "done-0001" has status "closed"
+    When I run "ticket archive done-0001"
+    And I run "ticket reopen done-0001"
+    Then the command should succeed
+    And ticket "done-0001" should remain active
+    And ticket "done-0001" should have field "status" with value "open"
+
+  Scenario: List includes archived closed tickets
+    Given a ticket exists with ID "done-0001" and title "Done ticket"
+    And ticket "done-0001" has status "closed"
+    When I run "ticket archive done-0001"
+    And I run "ticket ls --status=closed"
+    Then the command should succeed
+    And the output should contain "done-0001"
+
+  Scenario: Archived relationships require reopening
+    Given a ticket exists with ID "done-0001" and title "Done ticket"
+    And a ticket exists with ID "open-0001" and title "Open ticket"
+    And ticket "done-0001" has status "closed"
+    When I run "ticket archive done-0001"
+    And I run "ticket link done-0001 open-0001"
+    Then the command should fail
+    And the output should contain "must be reopened before editing relationships"
+
+  Scenario: Open ticket cannot be archived
+    Given a ticket exists with ID "open-0001" and title "Open ticket"
+    When I run "ticket archive open-0001"
+    Then the command should fail
+    And the output should contain "only closed tickets can be archived"
