Note for the maintainer: the CI run on this fork PR is sitting at action_required (first-time-contributor approval gate) — no jobs have started, so there is nothing to diagnose yet on my side. Once the run is approved and going, I expect exactly four printffmtparitycheck labels red by design (help, help_all, help_one, uses — help prose + legend bytes), and I will re-pin those hashes from the CI-reported actuals in a follow-up commit on this branch. Anything else red is a defect in the change and I will fix it here. |

Diagnosis of run 34864502790 (all three failure groups), plus a fix just pushed in c80b3be: 1. \printffmtparitycheck\ FAIL (\uses\ stdout e8eac2b7 -> 3ed4a98e) — STALE, no action needed. That run tested headSha \40e69fb; the re-pin commit \4efa187\ (manifest now carries \3ed4a98e, the fixed output) landed after. A re-run on current HEAD should clear this gate. 2. \usesselectorcheck\ order-gate (\call_sites\ used at line 170, defined at line 220) — REAL, fixed in \c80b3be. My rewrite left the helper defined with the (f)-arm helpers while arm (d) calls it earlier. Pure move of the byte-identical function above first use; no behavior change. 3. \elixirsemanticcheck\ \KeyError: 'result'\ — REAL, needs a maintainer call. The gate's MCP arm (\elixirsemanticcheck.sh:256-262) sends \ ools/call\ \uses\ with a ::\ selector (\Contracts::@limit) and asserts the MCP answer equals the CLI answer. My \mcpverbs.h\ change deliberately refuses ::\ spellings on that verb (JSON-RPC error reply, hence no Note: no C++ toolchain on this box, so CI is the proof for all of the above — the push will re-run the full matrix. |
…unt=0 Every symbol-taking verb resolves the canonical id and Scope::name spellings, but --uses kept the whole spelling as the site-match key against bare reference names. resolveUsesSelector now reads the match name off the resolved defs (scopeNarrowed) and narrows the call role through usesChosenCallers exactly as file:name does; --safe-delete and --verify ride the same scan. The MCP twin refuses a resolving :: spelling as CLI-only with the bare-name retry (never the silent zero). test/usesselectorcheck.sh: every KNOWN GAP arm flipped to its FIXED line plus same-rows and verbs-agree assertions; premises and controls untouched. Fixes redhat-et#164.
The legend and --help said narrowing was file: qualifier only; a narrowed :: answer would carry attrs its legend disowns. Shortest honest sentences: legend +2 B (3956 vs the 3979 budget), help +15 B. docs/COMMANDS.md prose and the newest capture re-derived by the same word substitution the binary emits, verified against docs_commands_build.py parse/join/split/caveats. The parity hashes for help/help_all/help_one/uses move with these bytes and are re-pinned from CI output next.
…heck The helper was defined at the bottom with the (f)-arm helpers but arm (d) calls it ~50 lines earlier, which the script-order gate flags (used at line 170, defined at line 220). Pure move, byte-identical body.

Rebase hygiene: rebased \ ix/uses-qualified-selector\ onto \upstream/main@30f14a2\ (was based on \�2f90ba). Before \c80b3bea61b62195227183b8d5dfaada9767f526\ -> after \ef0f9b81723af872e39caa2757c5ad2efc060bba, 4 commits carried, no logic changes. Conflict in \ est/printf_parity.manifest\ (re-pin commit): kept upstream \help/\pack_task\ pins, carried this PR's \uses/\help_all/\help_one\ pins. Caveat: merged help text is upstream changes + this PR's \cli.h\ delta, so \help_all/\help_one\ may need a fresh re-pin from CI actuals on this head — will follow up from CI output if \printffmtparitycheck\ reports new values. |

Align the Elixir MCP uses gate with the qualified-selector refusal.
test/elixirsemanticcheck.sh:256-262 calls MCP uses with the resolving, non-field selector Real.Work::defaults/2. usesSelectorRefusal rejects this selector, and src/mcp.h:1642-1646 returns a JSON-RPC error before calling usesText. The gate then reads reply['result'], so it fails on the refusal. test/regression.sh:271-274 runs this gate in ordinary CI.
Update the gate to assert the documented refusal and retry text, or implement narrowed MCP support consistently.

Preserve resolved member selectors.
For Owner::field, resolveFieldSelector skips the new :: refusal. qualifiedSelectorRefusal then rejects the selector when the bare field symbol exists. The MCP dispatch performs this refusal before usesText, so renderFieldUses never returns the member use-sites.
Allow a uniquely resolved field selector through before calling qualifiedSelectorRefusal.

Fixes #164.
--useson a::selector resolveddefs=and then answered a silentcount="0".Defect
Every symbol-taking verb resolves the two
::spellings the tool prints about itself — the canonical idpath::scope::nameandScope::name— throughresolveAllByNameQualified.--callers,--callees,--impactand--expandthen read the graph by NodeId, so the spelling stops mattering.--usesdid not:resolveUsesSelector(src/verbs_navigate.h) kept the whole spelling as the site-match key, andcollectUseSitescompared that key against reference names, which are always bare.defs="1"besidecount="0"reads as "defined, nothing uses it" — the misreading non-negotiable 3 exists to prevent — and--callers' ownnext=pointer sends the reader straight into it.--safe-delete'suses=,--verify="uses(...)"/"unused(...)"and the MCPusestwin ride the same scan/comparison.Reproduction (code path, no binary on hand — see the toolchain note):
sym.find("::")atresolveUsesSelectorforcedfileQualified=falseandsiteMatchName=sym;r.calleeName != sel.siteMatchNamethen skipped every reference. The pre-fix behavior is pinned onmaintoday by the 12 KNOWN GAP arms intest/usesselectorcheck.sh(each PASSes asserting the silent zero).Change
resolveUsesSelectortakes the resolveddefsand, for a::spelling whose defs are non-empty and share one name (commonDefsName, read off the defs — never a strip of the spelling), bindssiteMatchNameto that name and setsscopeNarrowed. The call role narrows throughusesChosenCallersexactly as afile:nameselector does; other roles stay name-matched. Mixed names (Elixir arity suffixes) keep today's whole-spelling key rather than a strip-and-match the precision controls forbid.Nope::ctwinkeeps the generic refusal's bytes, and member spellings with no symbol behind them still reachmemberUsesArmuntouched (it only fires on emptydefs).--safe-deleteand--verifyget the narrowed scan with no grammar change;--callers'next=is untouched (the sibling kit owns it).::spelling refuses as CLI-only with the bare-name retry and the CLI form — the wayfile:namealready refuses — instead of the silent zero. Member answers are exempt (consulted first, mirroring the CLI's member precedence). Tool descriptions untouched (the manifest ceiling has 23 B of headroom and this needs none).--helpsay what narrows now:A "file:name" or "::" SYM narrows ... (qualifier only). Legend +2 B (3956 vs the 3979 budget), help +15 B.docs/COMMANDS.mdprose and the newest capture re-derived by the same substitution the binary emits.What deliberately did not change: the
next=pointer, every "Not this issue" row in the kit, the per-enclosing-symbol narrowing granularity, and theOwner.fieldmember path (test/fieldusescheck.sharm F pinsTally::limitas the symbol spelling and only asserts rc/defs/no-member, all preserved).Tests
test/usesselectorcheck.sh: every KNOWN GAP arm (section f plus arm d) flipped to its FIXED line, plus the kit's two extra assertions — same-definition-same-rows (::vs the provenfile:nametwin, on the fixture and on this repo) and verbs-agree (everyrole="call"row sits inside a--callers-listed caller, viadeclinecheck.sh'scall_sitesrelation). Premises, controls, precision, negative and wrong-scope arms are byte-identical.gh, and Python via thepylauncher — so no local build or gate run was possible. Proof is CI on this PR: the flipped gate green, plus the full suite. I verified statically what can be verified statically: the COMMANDS.md prose againstdocs_commands_build.py's own parse/join/split/caveats (Answers, rest-prose, all 3 caveats match), the legend budget arithmetic, Allman/brace/span/container rules by review, and that no other caller of the oldresolveUsesSelectorsignature remains.test/printffmtparitycheck.shpins--help/--help=all/--help=--usesand the--uses=distanceanswer by SHA-256, and both changed bytes by design (help prose, legend sentence). No other label should move — every pinned selector is a bare name and the fix is confined to::spellings plus unconditional legend prose. I will re-pin exactly the red labels from CI-reported actuals in a follow-up commit on this branch, after reading which labels moved and why. If anything else moves, that is a defect in this change, not a pin update.
