Add the two PR commands that touch content and the local worktree:
- `pr diff <n>` fetches the raw diff from the `.diff` endpoint (forcing a
text response, which the JSON-defaulting client would otherwise discard),
truncates at 4000 chars with separate `truncated`/`original_length` fields
and a prepended `--full` suggestion; `--full` returns the raw diff.
- `pr checkout <n>` reads the PR head branch from the PR fetch and fetches
`refs/pull/{n}/head` from origin (uniform for same-repo and fork PRs, ADR
0011), three-cased on local branch state so re-checkout is idempotent and
divergent local commits fail with `GIT_ERROR` rather than being discarded.
Introduces the `GIT_ERROR` mapping (`runGit`) carrying git's first stderr
line plus a remediation help line, and widens the PR 404 classifier so a
`.diff` path still resolves to `PR_NOT_FOUND`.
Introduce the first mutations, along with the shared machinery the later
issue and PR mutation slices reuse.
- `issue create` with --title/--body/--body-file/--assignee/--label/
--milestone/--fields, emitting `issue: { number, title, state, url }`
- `issue comment <n>`, echoing the created comment from the POST response
with the body cleaned and truncated at 800 chars
- body-source resolution (--body vs --body-file), label and milestone
name->ID lookup, repeatable flags, and the `joined`/`selectExtraFields`
field extractors
Label lookup pages until exhausted, since a repo with more labels than one
page would otherwise fail to resolve a valid name. The end-to-end tier seeds
a mixed-case label and milestone and passes both in a different case, so the
case-insensitive lookup is verified against live Gitea rather than only
against fixtures.
Tracer bullet for gitea-axi: runnable npm package on axi-sdk-js with
gitea-js as the sole HTTP layer, ESM on Node 20+.
- issue list with --state/--limit, default fields, count line from
X-Total-Count, type=issues guard, explicit empty state, and next-step
suggestions
- repo context detection from the git origin remote (SSH/scp/HTTPS),
tea credential discovery with the three-way login-matching split, and
-R/--repo and --login overrides (flag > env > auto)
- token retrieval via tea login helper get: tea's login list JSON
carries no token (ADR 0001 amended)
- full AxiError classification table with path-based 404 split, TOON
errors on stdout, exit codes 0/1/2
- test mode (GITEA_AXI_API_URL/TOKEN/REPO) suppressing subprocesses,
fixture server, and vitest suites driving the CLI seam (50 tests)
