Implements Phase 1 of pull request support: tangled pr create/list/view.
Patch is generated via git diff, gzip-compressed, and uploaded as a blob
before creating the sh.tangled.repo.pull record. Includes behind-base
detection that prompts interactively or exits in --json mode.

getIssueState() now queries constellation.microcosm.blue for all state
records that reference an issue, fetches each one via getRecord, and
sorts by rkey (TID) to find the most recent. This allows collaborators
to close/reopen issues from their own PDS, fixing the old approach that
only ever saw the issue author's state records.

listIssues() now queries constellation.microcosm.blue for all issue
records referencing a repo, then fetches each one via getRecord. This
fixes multi-collaborator scenarios where team members host issues on
different PDSs — the old listRecords approach only saw the repo owner's
issues.

Introduces getBacklinks() which queries constellation.microcosm.blue to
find AT Protocol records that reference a given URI, across all PDSs.
This is the foundation for fixing multi-collaborator issue queries.

The current-session-metadata keychain entry was getting wiped by transient
errors (e.g. network failure on wake) in the resumeSession() catch block,
forcing users to re-authenticate unnecessarily.

Changes:
- Store session metadata in ~/.config/tangled/session.json (not keychain)
so it survives sleep/wake cycles and keychain lock events
- Don't clear metadata on transient agent.resumeSession() failures — only
clear when loadSession() definitively returns null (no stored credentials)
- Update session.test.ts to mock node:fs/promises with in-memory storage
- Update api-client.test.ts to reflect new non-clearing behavior

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

- Export KeychainAccessError from session.ts; thrown when getPassword() fails
(platform error like locked keychain), not when an entry is missing (undefined)
- resumeSession() now rethrows KeychainAccessError without clearing metadata,
so temporarily locked keychains no longer wipe stored credentials
- Add ensureAuthenticated(client) to auth-helpers.ts: on KeychainAccessError,
attempts to unlock the keychain via `security unlock-keychain` (macOS only),
retries once, then falls back to a clear error message with manual instructions
- Replace 7 repeated inline auth-check blocks in issue.ts with ensureAuthenticated()
- Add/update tests for KeychainAccessError propagation and ensureAuthenticated behavior

outputJson previously required Record<string, unknown>, which forced
callers to either use untyped objects or add a catch-all index signature
to typed interfaces like IssueData. Using a generic T extends object
allows any typed object to be passed while keeping the Record<string,
unknown> cast scoped to pickFields where dynamic key access is actually
needed.

All issue commands now return the full common field set (number, title,
body, state, author, createdAt, uri, cid) in --json mode:

- create: adds state:'open' (always open on creation)
- view: adds number via getCompleteIssueData (replaces separate getIssue
+ getIssueState calls)
- edit: adds number + state via parallel resolveSequentialNumber +
getIssueState after updateIssue (avoids re-fetching the updated record)
- close/reopen: adds body, author, createdAt via getCompleteIssueData with
stateOverride; replaces separate getIssue + resolveSequentialNumber calls
- delete: adds body, author, createdAt, state via getCompleteIssueData;
replaces scattered local variables

Update command tests to mock getCompleteIssueData and assert on the full
field set.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Move resolveSequentialNumber out of the commands layer into issues-api.ts
where it belongs alongside the other issue data functions. Add IssueData
interface as the canonical JSON shape for a single issue, and
getCompleteIssueData which fetches issue record, sequential number, and
state in one call (with optional state override for mutation commands that
already know the new state). Add tests for both new exports.

Addresses issues #8, #13, and #14:
- issue create now shows #N (sequential number) instead of the AT Protocol
TID rkey in human output, and includes `number` in --json output
- issue close, reopen, and delete now show the issue title in success output
- issue close, reopen, and delete now support --json with field filtering,
returning number, title, uri, state (close/reopen), and cid
- New resolveSequentialNumber() helper extracts number from displayId fast
path or falls back to listIssues lookup for rkey inputs
- 16 new tests added (281 total)

Adds GitHub CLI-style --json [fields] option to issue list, view,
create, and edit commands. When --json is passed, outputs machine-
readable JSON instead of human-readable text. An optional comma-
separated field list filters the output to only the requested fields.

Adds outputJson() utility to src/utils/formatting.ts for reuse
across future commands.

Replaces the skipped stdin placeholder with three real tests covering:
- reading a single data chunk from stdin
- concatenating multiple chunks
- propagating stdin error events

process.stdin is non-configurable on the real process object, so the
tests mock the entire node:process module using a Proxy that intercepts
the stdin property and returns a local EventEmitter fixture while
forwarding all other property accesses to the real module.

The readFromStdin Promise constructor registers handlers synchronously,
so events can be emitted immediately after readBodyInput returns its
pending Promise without needing setImmediate.

Implements the remaining issue management subcommands with full
lifecycle support:

- view: displays issue details including state (open/closed), author,
creation date, body; supports numeric (#1) and rkey identifiers
- edit: updates title and/or body via --title/-t, --body/-b, --body-file/-F
- close/reopen: toggle issue state; idempotent by design
- delete: permanently removes an issue; requires confirmation unless
--force is passed; cancel path uses process.exit(0) outside try/catch
to correctly propagate clean exit

Also:
- resolveIssueUri helper: on-demand numeric resolution by sorting issues
by createdAt (oldest = #1), no persistent cache needed
- list command updated to show numbered issues with state badges
- formatIssueState added to src/utils/formatting.ts
- All existing list tests updated for new output format; new test suites
added for all five commands covering auth, context, numeric/rkey
resolution, option validation, and confirmation flow

Extends the issues API layer with two new functions needed for full
issue lifecycle management:

- getIssueState: queries sh.tangled.repo.issue.state records to
determine open/closed status, defaulting to 'open' when no records
exist. Filters by issue URI and uses the most recent state record.
- reopenIssue: mirrors closeIssue by creating a state record with
state 'sh.tangled.repo.issue.state.open'

Includes tests covering state filtering, multi-record precedence,
unauthenticated error paths, and correct record creation.

Enable erasableSyntaxOnly and isolatedDeclarations for:
- Faster builds with parallel declaration generation
- Better compatibility with fast transpilers (esbuild, SWC)
- More explicit public API types

Add explicit Zod type annotations to validation schemas
to satisfy isolatedDeclarations requirements.

Fix issue where test files were excluded from TypeScript compilation,
causing VS Code to catch type errors that npm run typecheck missed.

Changes:
- Add "tests/**/*" to include array in tsconfig.json
- Remove "tests/**/*" from exclude array
- Tests are now type-checked by both build and typecheck scripts
- Tests are emitted to dist/tests/ (harmless locally, can exclude from npm publish later)

This ensures type errors in tests are caught by:
- npm run typecheck (local development)
- npm run build (before commits)
- CI pipeline (prevents broken tests from being merged)

New utilities:
- Add formatDate() in src/utils/formatting.ts
- Converts dates to human-readable format (today, yesterday, X days/weeks/months ago, or locale date)
- Comprehensive test coverage with 9 tests

Implementation:
- Add createListCommand() with limit validation
- Import formatDate from utils/formatting.ts
- Add 9 comprehensive command tests

Tests:

Issue records were not appearing on tangled.org because the repo field
used an incorrect AT-URI format with the repository name as the rkey
instead of the actual record key.

Changes:
- Update buildRepoAtUri() to query PDS for sh.tangled.repo records
- Find matching repository by name field in record value
- Return record's URI which contains the correct rkey
- Add comprehensive tests for new query-based resolution

- Define IssueRecord interface locally in issues-api.ts
- Based on sh.tangled.repo.issue lexicon schema
- Includes required index signature for AT Protocol compatibility
- Documents lexicon source for reference

- Avoids TypeScript compilation issues with generated lexicon types
- Maintains full type safety while working around codegen limitations

This approach is recommended in src/lexicon/README.md and provides
a stable interface that won't break when lexicons are regenerated.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

- Update tsconfig.json:
- Exclude src/lexicon/** from compilation (generated code has compatibility issues)
- Exclude tests/**/* from build output (tests are type-checked separately)
- Only include src/**/* in build

- Regenerate lexicons with post-processing fixes applied:
- All multiformats/cid imports now use main package export
- All relative imports now have .js extensions

- Add comprehensive src/lexicon/README.md documenting:
- Code generation workflow
- Dependencies and multiformats usage
- Recommended usage patterns (custom interfaces)
- Known issues and workarounds
- Troubleshooting guide

This allows TypeScript to compile cleanly while still providing type
information from generated lexicons for IDE support.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

- Add multiformats@9.9.0 as direct dependency for CID type support
- Create scripts/fix-lexicon-imports.js to post-process generated lexicons:
- Adds .js extensions to relative imports for ES module compatibility
- Rewrites 'multiformats/cid' imports to 'multiformats' main export
(fixes TypeScript NodeNext module resolution issues)
- Update codegen script to run post-processor automatically

This resolves TypeScript compilation errors with generated AT Protocol
lexicon code while maintaining strict type checking in application code.

Add the base issue command structure with create subcommand:
- Command accepts title argument and optional body via --body or --body-file
- Validates authentication and repository context
- Builds AT-URI and creates issue record via AT Protocol
- Displays success message with issue number (rkey) and URI
- Comprehensive tests covering all input methods and error cases

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

This pipeline runs on every push to any branch and ensures:
- Code follows linting standards (Biome)
- TypeScript compilation succeeds
- All tests pass

- updateIssue(): Update issue title and/or body with atomic CID swap
- closeIssue(): Mark issue as closed via state record
- deleteIssue(): Permanently delete an issue

Features:
- Uses generated lexicon types (IssueRecord) for type safety
- Uses requireAuth() helper for authentication validation
- Uses parseIssueUri() internal helper to eliminate duplication
- Clear error messages with context
- Repository filtering in list operations
- Ownership verification for update/delete

Includes comprehensive test coverage (23 tests passing)

Extracts duplicated auth validation logic into reusable utility:
- requireAuth(): Validates client is authenticated and has active session
- Throws clear error messages if not authenticated
- Returns session with DID and handle

This helper will be used across all API operations that require
authentication, ensuring consistent error messages and reducing
code duplication.

Includes test coverage (3 tests passing)

Supports multiple input methods following GitHub CLI patterns:
- Direct string input via --body flag
- File input via --body-file <path>
- Stdin input via --body-file - (tested via integration tests)

Features:
- Validates that only one input method is used
- Handles empty strings correctly
- Clear error messages for file not found, permission denied, etc.

Includes comprehensive test coverage (12 tests passing)

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

New utilities:
- parseAtUri(): Parse AT-URI into components (did, collection, rkey)
- resolveHandleToDid(): Resolve handle to DID via AT Protocol
- buildRepoAtUri(): Construct repository AT-URI from owner and repo name

New validation schemas:
- issueTitleSchema: 1-256 characters
- issueBodySchema: Optional, max 50,000 characters
- atUriSchema: Validate AT-URI format

Includes comprehensive test coverage (45 tests passing)

Generated type-safe client code from vendored lexicons using @atproto/lex-cli.
Includes type definitions for:
- Issue management (sh.tangled.repo.issue)
- Pull requests (sh.tangled.repo.pull)
- Repository operations
- All Tangled-specific record types

Note: Generated code committed to version control for:
- Reviewability in PRs
- No build step required for type checking
- Offline development support

We'll use the type definitions (interfaces) for type safety while calling
AT Protocol APIs directly via @atproto/api to avoid module resolution issues
with the generated client methods.
