refactor(cli): palace unavailable exits 2 everywhere; one daemon-failure helper (#523, #514) by jphein · Pull Request #522 · techempower-org/mempalace

jphein · 2026-09-18T05:19:05Z

_fail_daemon exits 1 — "no results" — for every daemon outage. It still does on today's main; this is the first change that moves it.

⚠️ Issue-number correction: this work and #517 were labelled #476 from a plan note. #476 is "maintain-fork-changes.py: positional #NN resolver writes wrong shas" and is unrelated; the real issue is #523. #517's squash subject says #476 and cannot be rewritten — its changelog entry was never affected. Every #476 in this branch's code, tests and entry is corrected, except four citations that genuinely refer to the fork-changes resolver.

A command reporting "no results" when the daemon is down sends the reader looking for missing data instead of a missing daemon. That is the defect family this wave exists to remove, sitting in the exit status after being fixed in the prose.

The contract

0   success
1   no results — the operation RAN and selected nothing
2   the operation could not run: palace unavailable, or a usage error
64  the daemon answered and REJECTED a well-formed request (a 4xx)

⭐ 1 vs 2 is the load-bearing line. 1 means the palace was reachable and had nothing to say; 2 means the question never got asked.

Three helpers, three different answers

_daemon_tool_or_fail's MESSAGE is consolidated into _fail_daemon; the wrapper remains. It is still defined, still has its six callers, and still owns the DaemonRequestError → 64 branch — what moved is its duplicated failure-rendering body, which now delegates with a new tool= kwarg carrying the tool name into prose and JSON.

That consolidation was not possible in #517: it exited 1 if unreachable else 2 while the shared helper exited 1 for both, so merging the message then would have forced one exit code onto two situations in six commands, as a "cleanup". The two now converge: its transport branch moves 1 → 2, its JSON-RPC branch is unchanged at 2, and the distinction between them survives in the prose only.

_fail_daemon_unavailable (#512) is NOT folded, and the reason is the useful part. Its docstring said to delete it "if _fail_daemon ever does move to 2". This moves it — and the cited test still passes, because it asserts only the exit code. The JSON shapes differ:

_fail_daemon_unavailable   {"error": "daemon_unavailable", "message": <prose>}
_window_route_failed       {"error": <key>, "message": <prose>, "status", "route"}
_fail_daemon               {"error": <prose>, "source": "daemon"}

window/source use key + message across the family so a client can branch on error; _fail_daemon puts the prose in error. Folding would have changed two verbs' machine output, left them inconsistent with their own sibling, and every test would have stayed green because nothing asserted the shape.

⚠️ A retirement condition written in exit-code terms is satisfiable without being sufficient. Its docstring now records the real one — delete it when the two families agree on a JSON shape — and test_transport_failure_json_keeps_the_window_family_shape makes the next attempt fail loudly. Convergence is #521.

`cmd_pending` and #514

cmd_pending's unknown-action guard moves 64 → 2 and routes through _fail_client. A verb group named without an action is a usage error, the same class as argparse's "invalid choice"; 64 now means exactly one thing. It also gains a JSON document — a hand-rolled print(..., file=sys.stderr) gives a --json caller prose and no document at all.

The header claimed 64 bad args (argparse default for parse errors). argparse exits 2, and nothing in mempalace/ subclasses ArgumentParser or overrides error(), so that row described a behaviour this CLI never had. It survived for years because the contract lived in prose that nothing executed — so two tests now make it falsifiable: one asserts the header says what the code does (and that the false sentence never returns), the other asserts the absence of an ArgumentParser subclass, since argparse's 2 only reaches the shell while nobody overrides error().

The worklist was derived by execution, not grep

Flip the helper, run the suite, classify every failure. Two careful greps were both 3–4× short:

estimate	scope	value
"34 test files asserting exit 1"	wrong question — counts no-results 1s	—
files quoting the unreachable literal	grep	5
`_fail_daemon`'s callers	grep	4
union of those two	grep	~9
flip the helper back to 1 and run the suite	execution	49 tests across 19 files

⭐ Both greps missed for one reason: a test named test_daemon_unreachable_exits_1 asserts only the exit code. It never quotes the message, so no text search can find it.

The numbers, by unit — because they are not the same count

unit	value
files that pin this behaviour	19 ← the invariant
tests failing when the helper is flipped back	49
assertions this PR moved `1 → 2`	43 line edits + 1 constant (`_DAEMON_FAIL_EXIT`, covering 2 more)
tests failing at derivation time, before later merges	42

⚠️ An earlier revision of this body said "45", which was a real measurement of the wrong unit — assertions, presented against a tests-derived arithmetic (42 + 2 + 3 = 47) that does not reach it either. Four denominators are in play here: assertions, tests-that-failed-at-derivation, tests-that-now-pin-the-behaviour, and files. Only the file set is stable under renames, splits and a constant covering two assertions, which is why it is the stated invariant.

⚠️ And a derived list is a snapshot. The 42 was correct when derived and was invalidated twice within the hour — once by coverage rows added to #517, once by #510's diary split merging.

Two categories, and why the second is empty by construction

(a) outage expectations → 2. All 45.

(b) a no-results assertion failing → a bug. Zero — and not "none found". _fail_daemon is only called from daemon-failure branches, so a no-results path cannot reach it and cannot appear in this list. The ~31 files asserting 1 for genuine no-results are untouched and still pass. Flipping those would report an empty result as an outage: the wave's own defect, re-created by its fix.

The diary family is a one-line edit, as its author intended — two of its three assertions go through _DAEMON_FAIL_EXIT, a constant whose comment says it exists "so the rebase that changes it is a one-line edit rather than a hunt… this stays 1 until someone owns that cross-cutting change." This owns it. The third test moved onto the constant; TestDiaryReadNoResultsExitCode keeps a literal 1 with a warning saying why.

32 tests renamed from *_exits_1 to *_exits_2 — a name asserting one number while the test asserts another is a name disagreeing with its own behaviour. test_daemon_unreachable_exits_1 became ..._uses_the_daemon_failure_code, because a name encoding a number the constant exists to move will lie again.

Named residue

401/403 from the daemon: 2 (unavailable) or 64 (rejected)? decide once, apply everywhere #518 — should 401/403 be 64 (the daemon answered and refused) rather than 2? Needs _call_daemon_rest to stop collapsing 404/401/403 to None first, so a caller can tell them apart at all.
cli.py has two JSON error conventions — {error: prose, source} vs {error: key, message}; decide one, then retire _fail_daemon_unavailable #521 — cli.py has two JSON error conventions; decide one, then retire _fail_daemon_unavailable.

Closes #514
Closes #523

📝 Walkthrough

Walkthrough

The CLI now uses exit code 2 for daemon outages, transport failures, JSON-RPC failures, and usage errors. Exit code 1 remains for successful operations with no results. Exit code 64 remains for daemon refusals. Tests and documentation were updated.

Changes

CLI exit-code contract

Layer / File(s)	Summary
Contract and usage-error handling `mempalace/cli.py`, `tests/test_cli_palace_exit_codes.py`, `website/reference/python-api/cli.md`	The documented contract now assigns 2 to operations that cannot run and usage errors. `cmd_pending` uses `_fail_client` and supports JSON output. Contract tests cover argparse, pending actions, daemon refusals, and daemon outages.
Daemon failure routing and JSON shapes `mempalace/cli.py`, `tests/test_cli_window_source.py`	`_fail_daemon` exits 2 and reports reachability details. `_daemon_tool_or_fail` routes transport failures to `_fail_daemon` and daemon refusals to exit 64. Window/source JSON output retains its existing error shape.
Failure-path test alignment `tests/test_cli_bulk_move.py`, `tests/test_cli_cypher.py`, `tests/test_cli_diary.py`, `tests/test_cli_drawer.py`, `tests/test_cli_duplicate.py`, `tests/test_cli_graph.py`, `tests/test_cli_kg.py`, `tests/test_cli_list.py`, `tests/test_cli_move.py`, `tests/test_cli_overlap.py`, `tests/test_cli_rate.py`, `tests/test_cli_read_family.py`, `tests/test_cli_stats.py`, `tests/test_cli_tags.py`, `tests/test_cli_tunnels.py`, `tests/test_cli_walk.py`, `tests/test_cli_why.py`, `tests/test_cli_fail_daemon_one_message.py`	Daemon failure expectations and test names now use exit code 2 across the affected CLI commands.
Fork-change records `FORK_CHANGELOG.md`, `docs/fork-changes/2026-09-17-palace-unavailable-exits-2.yaml`, `README.md`, `website/public/llms-full.txt`	Project and website records document the revised exit-code contract and pending fork change.

ISSUE-NUMBER CORRECTION: this work and #517 were labelled #476 from a plan note. #476 is "maintain-fork-changes.py: positional #NN resolver writes wrong shas" and is unrelated; the real issue is #523. 15 references corrected here. Four are deliberately NOT corrected — tests/test_maintain_fork_changes.py (2), tests/test_render_docs.py (1), tests/test_fork_changes_loader.py (1) — because they cite the REAL #476. A blanket replace would have corrupted all four, the same mistake as a blunt sed over the diary tests earlier in this branch: the scoped edit is the default, and blast radius scales with matches rather than targets. #517's squash subject says #476 and cannot be rewritten; its changelog entry never carried an issue number, so the rendered changelog was never wrong. Residue, named rather than folded in: #518 should 401/403 be 64 rather than 2? Needs `_call_daemon_rest` to stop collapsing 404/401/403 to None first. #521 cli.py has two JSON error conventions; decide one, then retire `_fail_daemon_unavailable`. Closes #514 Part of #523 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

seq 156 from `--next-seq` after the final fetch; `commit: HEAD`; `fork_pr: 522`. The entry records the #476 → #523 mislabel so a reader of #517's immutable squash subject is not misled. Wording corrected with the code: `_daemon_tool_or_fail`'s MESSAGE was consolidated and the wrapper REMAINS with its six callers, and the two helpers CONVERGE rather than become identical. The worklist is stated by unit — 19 files as the invariant, 49 tests failing on a flip-back — because an earlier revision quoted 45, which measured assertions against a tests-derived arithmetic that did not close. `website/reference/python-api/cli.md` moves because `_fail_daemon`'s and `_daemon_tool_or_fail`'s docstrings changed, not because of the entry.

Resolve the conflicting exit-code contract for cmd_source.

When --file is omitted, cmd_source emits a local usage error and exits 64. The source-specific test also documents and asserts 64, while the revised CLI contract assigns usage errors to 2 and reserves 64 for daemon refusals. If 2 is intended, call _fail_client and update the test; otherwise document this explicit source exception.

Preserve HTTP response semantics.

_call_daemon_tool catches HTTPError through its URLError handler. It therefore converts both HTTP 4xx and 5xx responses into an unreachable DaemonError. _fail_daemon then reports reachable: false and exits 2.

Handle HTTPError by status class. Map 4xx responses to the typed daemon-refusal path with exit 64. Map 5xx responses to exit 2 while reporting reachable: true. Preserve reachability as structured exception state instead of inferring it from error text.

) (#520) * fix(check-docs): examine every mention of a PR, not just the first Step 4 did `grep … | head -1` per document, so only the FIRST line mentioning a PR number contributed to that document's claimed state. The check answered "does the first mention agree?" rather than "do all mentions agree?", and a drifted claim appearing after a correct one was invisible. Reproduced on the real repo before fixing: appending PR MemPalace#1377 is still open upstream. to the end of README.md, with MemPalace#1377 MERGED upstream, left check-docs reporting "✓ all 245 PR references match upstream state". The control was confirmed reachable BEFORE its silence was trusted: the appended line is in the instrument's own match set (line 477 of 5 matches), while `head -1` selects line 30 — which mentions MemPalace#1377 and claims nothing. A control that is present but never looked at produces "did not fire" for the wrong reason, and that reads identically to "no drift". Three defects, now one scan: - Only the first line was read. Every matching line is now, with the multi-PR commentary skip applied per LINE rather than zeroing a whole document's claims. - No right boundary. The claim scan used (#$n|/$n), so `#45` matched `#452` and `/45` matched `/459efab`, while the commentary scan beside it used [^0-9] — the two loops could read different lines and reach a conclusion neither line supported. One scan, one regex, anchored on a non-digit or end of line. - State words matched as substrings. "opencode", "openai-compat" and "reopened" all contain "open" and were read as a claim of OPEN. Latent while one line per doc was examined; amplified the moment every line is. Measured differentially over the whole repo with every PR stubbed MERGED: 7 findings before, 7 after — and five different ones in each direction. removed (false positives): #45 read off a line about #452 #56 "OpenCode adapter smoke test" #463 "openai-compat embedding" MemPalace#1567 ".opencode/opencode.json" MemPalace#2062 v3.8.0 sync line found (never examined): #23 "PR #23 is still OPEN but" #168 "#168 itself stays open" MemPalace#665 "*Upstream:* [PR MemPalace#665] (OPEN)" MemPalace#1087 "(OPEN)" MemPalace#1094 "(open upstream, jp-authored)" The unchanged total is the trap: a reader checking whether the count moved would conclude nothing had. Also removes both shellcheck errors in the file (SC1087 — `$n[` read as array indexing) and adds none; the two remaining warnings are pre-existing. Known limit, asserted in a test rather than left implicit: when one clean line claims the true state and another claims a different one, drift cannot be distinguished from history, and the PR is skipped. MemPalace#1024 in FORK_CHANGELOG.md is exactly that shape — "pushed to the open MemPalace#1024 PR branch (squash-merged upstream)" alongside an authoritative "(MERGED)" — and is correct documentation of a MERGED PR. It is the only such pair in the repo, which is why flagging disagreement was rejected. Tests: 11 new in tests/test_check_docs_pr_state.py, driving the real script over a fixture tree with a stubbed `gh` (no network, no shared API quota). Four guards mutation-verified, each mutation asserting its target exists so a mutation that fails to apply reports loudly instead of as "nothing to guard": restore head -1 -> 3 tests remove the word boundary -> 2 remove the commentary skip -> 1 drop the right boundary -> 1 Three of those tests were not evidence when first written and were rebuilt: the harness sliced output between step headings while findings go to stderr (so every "no finding" assertion passed vacuously); the commentary test claimed a state the MERGED branch ignores; and the boundary test used a number the check never queried. Each now fails under the old behaviour. check-docs passes on itself. Full suite 7443 passed, 82 skipped. Part of #516 Fixes #516 * fix(check-docs): a state WORD is not a state CLAIM; /pull/N, not /N Follow-up on the same PR, applying nebula's measurement from the issue thread. The first pass fixed `head -1` and matched state words as whole words; that was not enough, and I could prove it only after running the check with REAL upstream states. Two corrections to my own verification first, because they are why this was nearly missed: * My "no new false positives" run used a stub that returned a state for ONE pr number and nothing for the rest, so every other PR was skipped. "Clean" there proved nothing. With real `gh` the fix ADDED a warning. * The control line nebula cited (FORK_CHANGELOG.md L246) is blank in this tree — the measurement was taken on another branch. Found by content instead: it is L358 here, and L356 is a worse case nebula predicted but could not see. Measured with real states, before this commit: NEW script: 2 warnings (MemPalace#1377, #459) OLD script: 1 warning (MemPalace#1377) Both causes are the same defect from the other end. `head -1` decided WHICH lines are read; this decides WHAT counts as a claim on a line. #459 README.md:297 and FORK_CHANGELOG.md:356 are the heading "purge / prune / mined share one open-and-refuse sequence", linking commit `459efab`. There is no #459 on either line — `/459` matched inside the COMMIT HASH, and "open-and-refuse" supplied a whole-word "open". A right boundary does not help: `/459` is followed by `e`. MemPalace#1377 FORK_CHANGELOG.md:81 was MY OWN changelog entry, quoting the control sentence verbatim. The entry documenting the defect reproduced it — the `self-quoting-retraction` shape from the #503 spec, which is how #511 went green and then warned again once its own entry landed. So, three rules now: * `/pull/$n`, never a bare `/$n`. A commit hash is not a PR reference. * A state word must appear in a CLAIM SHAPE — a parenthesised marker "(OPEN)", or a copula "is/was/stays/remains/now [still] open". Checked against all 13 cases in this repo: every real claim kept (#23 "is still OPEN", #168 "stays open", MemPalace#665/MemPalace#1087 "(OPEN)", MemPalace#1094 "(open upstream"), every prose case dropped ("open-and-refuse", "open the drawers", "opencode", "openai-compat", "reopened"). * The entry for this change does not quote its own control sentence. It states a MERGED claim for MemPalace#1377, which is what MemPalace#1377 is. Result with real `gh` on the repo itself: both the base script and this one report zero PR-state warnings. The base's cleanliness is incidental — its `head -1` happens to land on a line without a claim, and moved there only because #509/#512/this entry changed the changelog. This one is clean for a reason. shellcheck findings 4 -> 2 (both remaining are pre-existing warnings; both former ERRORS are gone). Tests: 5 more (state word without a claim; nebula's "open the drawers" with the PR alone on the line, since the real one is spared only incidentally by a second PR sharing it; a commit hash is not a PR reference; a /pull/ URL still counts; a parenthesised marker is still a claim). 16 total, and two more mutations verified with the target-exists assertion: claim shape -> bare word -> 3 tests /pull/N -> /N -> 2 tests One test asserted something the check cannot do — a PR referenced only by URL is never examined, because the number list is harvested from `#NNNN` alone. Pre-existing and out of scope; the test now says so rather than pretending to cover it. Full suite 7448 passed, 82 skipped. check-docs passes on itself. Part of #516 * docs(fork-changes): renumber to seq 157 after the #511/#522 rebase Rebased onto 4c6a8d0. `--next-seq` re-run after the final fetch says 157; taken from the tool rather than assumed. Generated artefacts re-rendered from main's side, never hand-merged. Part of #516
