docs(jq): record map_values(first)'s path-error message residual and pin it (#3884)

[newhoggy]

Summary

Fixes #3884. The issue asks to confirm the map_values(first) fold-source route is covered by the #3271 residual record, or to align the wording. Probing it shows the divergence is the by-value ordering tradeoff of #3271, not a fold-source quirk: it is identical for plain path(map_values(first)).

• On a scalar element jq raises its path error first (near attempt to access element 0 of 1); this resolver evaluates the body by value and raises jq's type error (Cannot index number with number).
• Where the path error is raised, it names the container the construct produced (element 0 of {"a":1,"b":null}), not the element first indexed ([1] in jq).
• Stdout and exit code match jq 1.7.1 on every row (nothing, exit 5).

Naming the element would need the resolver to run the map_values body in path mode per element, which is the broader #3271/#2743 design the limitations record already declines, so this records the residual (both the type-error ordering and the container naming, as a path and as a fold source) in docs/compliance/jq/limitations.md and pins the messages with test_map_values_first_path_error_message_residual_3884. No behaviour change.

Test plan

• cargo test --features cli,simd,regex,serde (all passing)
• cargo clippy --all-targets --all-features -- -D warnings
• cargo clippy --all-targets --features std,simd,serde,cli,regex,bench-runner,large-tests,mmap-tests -- -D warnings
• cargo fmt --check
• Every pinned row captured against /usr/bin/jq 1.7.1 (jq's own messages are in the test comments)

File	Kind	Lines	Rev	Reason
src/bin/succinctly/jq_runner.rs	tolerate	1332	both	unreachable: widening the shadow-candidate set never rejects a program the first parse accepted, for the identical reason run_jq's own analogous fallback (#2395) is tolerated -- see that line's own comment (#2950)
src/bin/succinctly/jq_runner.rs	tolerate	1705	both	unreachable while the walk and the loader agree on what fails: both resolve with resolve_module_in/resolve_data_file_in, parse with parse_program and name a cycle by canonical file, which the fuzz in #3573 held over thousands of programs; kept so drift prints the loader's failure and not 0 compile errors
src/bin/succinctly/jq_runner.rs	tolerate	2422-2434	both	unreachable: try_parse_meta_op only fires under ParserMode::Yq (src/jq/parser.rs), and rewrite_namespaced_calls is only reached via ModuleProcessor::process_program, which jq_runner's own jq-mode run is the sole caller of -- so a MetaAssign node can never reach this function (#798)
src/bin/succinctly/jq_runner.rs	tolerate	3022	both	unreachable by construction: every error this wrapper receives today is a decode or nesting-depth failure the evaluator raised itself, never error(v); kept so a future one is rendered rather than dropped (#2999)
src/bin/succinctly/jq_runner.rs	tolerate	3023	both	see the arm above (#2999)
src/bin/succinctly/jq_runner.rs	tolerate	3442	both	unreachable in practice today: def is only None when occurrences.module_def() is None, which (given origin is Some) would require an open run whose innermost frame has no def set at a check point that isn't itself inside a module-level def body -- but every module run is a strict chain of def nodes (the loader's own defs, each wrapping its dependency stubs INSIDE its own body via wrap_defs/dep_stubs_for) terminated by the run's own end marker, so a diagnosable call/var/break site is always reached either inside a module-level def's body (module_def Some) or outside every run (origin None) -- and even when def is Some, self.defs is always ModuleSource::read's own re-parse of the exact same file run_id_for interned this origin's id from, so collect_def_sites always finds the matching (name, arity, ordinal) span. Kept as a defensive fallback rather than a panic/unwrap in case that invariant is ever violated (#3085)
src/bin/succinctly/jq_runner.rs	tolerate	3691-3694	both	unreachable in a single-process run by construction: run_id_for (the sole source of an origin id) always inserts a run_origins entry for the id it hands back -- from a real load's canonical path, or its own literal-path fallback on a resolve failure -- and a def body only ever gets stamped with an origin after its module loaded successfully, so at always names a file that existed and was readable moments earlier. Reaching this arm needs that same file to vanish (or become unreadable) in the narrow window between that load and this re-read, entirely outside this process's control (#2964)
src/bin/succinctly/jq_runner.rs	tolerate	3960	both	unreachable: widening the shadow-candidate set never rejects a program the first parse accepted -- a newly covered name only wraps an already-successful dedicated parse, and a failing one would have propagated its error in the first parse too, so the retry budget is charged at the identical sites in both (#2395)
src/bin/succinctly/jq_runner.rs	tolerate	4551-4587	both	unreachable from any query this suite can build since #3457: the path walkers were the sites that panicked at MAX_NESTING_DEPTH here (sort/join/map, path()/paths/setpath/del()/assignment on a deep document), and they now return a decode-failure-tagged error, so a deep document is reported through the ordinary Err arm instead. The panic sites still in the evaluator (lazy.rs cursor_to_owned, owned_identity_recurse_step, owned_from_standard_json_at_depth, the YAML comment-preserving materialization) are not reached by a jq-mode CLI query at 250-500 levels, probed by hand; the catch is kept as the net for them and for a future guard that panics, and nesting_depth_panic_message itself is pinned by a unit test (#3457)

src/jq/eval.rs	tolerate	10679	both	reachable only on a genuine allocation failure: owned_assign_step's single-step arms map every non-allocation error to unreachable_owned_assign_write (provably impossible, see its own doc comment), and its Chain arm's set_path call walks exactly the steps owned_assign_step_child already validated as Field-into-Object/Null or Index-in-[0,len]-into-Array/Null with no mutation in between, so the only way set_path/set_field/set_index/pad_with_nulls can still fail is the same try_reserve-fails-under-OOM branch the codebase already tolerates elsewhere (#2267) (#3138)
src/jq/eval.rs	tolerate	10799	both	unreachable: owned_assign_shape's only caller (owned_step_shape) gates the call on is_owned_assign(expr), which recognizes exactly Assign/Update/CompoundAssign/AlternativeAssign -- the same four variants this match already has explicit arms for, so expr can never be anything else here (#3138)

src/jq/eval.rs	tolerate	14571-14573	both	unreachable: builtin_length's sole caller is eval_builtin's Builtin::Length dispatch, and Length is in builtin_operand_is_input, so eval_builtin's own top-of-function guard already returns the identical decode_failure for an Error value before this match ever runs; kept as this function's own contract in case a future caller reaches it directly (#3222)
src/jq/eval.rs	tolerate	14794-14796	both	unreachable: has_one_key's sole caller is builtin_has (via eval_builtin's Builtin::Has dispatch), and Has is in builtin_operand_is_input, so eval_builtin's own top-of-function guard already returns the identical decode_failure for an Error value before builtin_has ever runs; kept as this function's own contract in case a future caller reaches it directly (#3222)
src/jq/eval.rs	tolerate	18081	both	unreachable: entry is one of to_entries's already-materialized {key,value} pairs, so its depth here is provably no deeper than whatever earlier check let it exist -- a document-decoded entry is already <256 deep (MAX_NESTING_DEPTH, stricter than this 384 guard), and a filter-constructed one already survived becoming a cursor via its own whole-object reindex, which is strictly deeper than any single field extracted from it could be (unwrapping only reduces depth); confirmed live, {a: (reduce range(400) as $i (0; [.]))}

Pre-existing; #2694 only wrapped the return in Some (#2694)
src/jq/eval.rs	tolerate	40769	both	unreachable, as this arm's own comment above says: indexing or slicing a value yields zero or one result, so is_primitive never produces more than one -- kept as a named error rather than a panic.

src/jq/eval.rs	tolerate	60675	both	unreachable in the current test suite: eval_path_context_pipe_owned itself has zero total call-site coverage today (not just this arm), confirmed by a full-suite eprintln probe across every test binary -- reaching its error arm needs first solving how to reach the function at all, out of scope for #3261's reindex-bridge fix

src/jq/eval_generic.rs	tolerate	28863	both	the CLI evaluates every program that uses input/inputs on the eager route (jq_runner's can_use_lazy_path excludes them), so this guard never fires today -- #2968's identical guards on the arms above are equally unfired; kept for the day the lazy path admits such a program (#1309)
src/jq/eval_generic.rs	tolerate	28869	both	see above: the input-queue deferral never fires from the CLI
src/jq/eval_generic.rs	tolerate	30358	both	unreachable by construction: every shape either guard admits now has an arm above (#2771), and expr_dispatch_catchall_guards_default_conservatively_2549 pins both guards' _ => false defaults directly
src/jq/eval_generic.rs	tolerate	31014	both	unreachable in a passing suite by design -- owned_identity_rule maps a bare Expr::Var to Bound too (for the static gate, which sees a body before its as substitution runs), but every runtime dispatch that reaches this rule (owned_identity_after_stage/owned_identity_placed_by, from owned_identity_leaving_cursor's Bound arm) only ever sees a stage after eval_owned_identity_as's unconditional substitute_bound_var_from call, which always turns $x into Expr::TrackedVar before recursing -- confirmed by running the full suite with this arm replaced by a hard panic!(), which never fired (#2072)
src/jq/eval_generic.rs	tolerate	31032	both	unreachable: this Slice rule's own two execution paths both exclude Expr::Slice before ever reaching owned_identity_placed_by -- eval_owned_identity_stages's catch-all only runs a stage owned_identity_nav_supported refused, and owned_identity_leaving_cursor (identity_from_first, eval_generic.rs:10724) only runs a stage path_context_is_navigational refused -- and both predicates admit Expr::Slice (owned_identity_nav_supported/path_context_is_navigational_at each list Expr::Slice { .. } => true), so a bare slice is always resolved by owned_identity_step's own arm first. Kept in owned_identity_rule's match for exhaustiveness/symmetry with the rule table's other entries, the same reason #2072's Bound arm above is kept unreachable-by-construction (#2966's review of #2834)

src/jq/eval_generic.rs	tolerate	32657	both	optional is never true through this pipe: ? is eval_owned_identity_try, which catches the escape instead, and after #693 only the IndexExpr/SliceExpr special case ever sets it -- kept as any_all_f's scalar_fallback mirror

src/jq/resolve.rs	tolerate	2949	both	unreachable in practice today: this arm needs builtin_fallback==None (the name was never a shadow candidate) yet is_jq_builtin==true (a real jq builtin at this arity) -- every implemented builtin's own dedicated parse already lowers that shape to Expr::Builtin before resolve.rs ever runs, and #3042/#3046 closed the once-real 'unimplemented builtin' gap this existed for (see JQ_BUILTIN_ROSTER's own doc comment)
src/jq/resolve.rs	tolerate	2951	both	unreachable with the current roster: every JQ_BUILTIN_ROSTER entry of arity >= 1 already has a dedicated parser form (a matches_keyword special case or a Libm1/Libm2/Libm3::ALL entry -- confirmed by cross-referencing the full roster against both), so it is parsed straight to Expr::Builtin and never reaches here as a bare FuncCall. This arm exists for a roster name with no dedicated parse yet and a nonzero arity -- there is none today, so the loop body is reached with an empty args on every pinned-suite run (355 hits on the arm's own condition, 0 in the loop) and would only start executing if such a name were added (#2964)

File	Kind	Lines	Rev	Reason
src/bin/succinctly/jq_runner.rs	tolerate	1332	both	unreachable: widening the shadow-candidate set never rejects a program the first parse accepted, for the identical reason run_jq's own analogous fallback (#2395) is tolerated -- see that line's own comment (#2950)
src/bin/succinctly/jq_runner.rs	tolerate	1705	both	unreachable while the walk and the loader agree on what fails: both resolve with resolve_module_in/resolve_data_file_in, parse with parse_program and name a cycle by canonical file, which the fuzz in #3573 held over thousands of programs; kept so drift prints the loader's failure and not 0 compile errors
src/bin/succinctly/jq_runner.rs	tolerate	2422-2434	both	unreachable: try_parse_meta_op only fires under ParserMode::Yq (src/jq/parser.rs), and rewrite_namespaced_calls is only reached via ModuleProcessor::process_program, which jq_runner's own jq-mode run is the sole caller of -- so a MetaAssign node can never reach this function (#798)
src/bin/succinctly/jq_runner.rs	tolerate	3022	both	unreachable by construction: every error this wrapper receives today is a decode or nesting-depth failure the evaluator raised itself, never error(v); kept so a future one is rendered rather than dropped (#2999)
src/bin/succinctly/jq_runner.rs	tolerate	3023	both	see the arm above (#2999)
src/bin/succinctly/jq_runner.rs	tolerate	3442	both	unreachable in practice today: def is only None when occurrences.module_def() is None, which (given origin is Some) would require an open run whose innermost frame has no def set at a check point that isn't itself inside a module-level def body -- but every module run is a strict chain of def nodes (the loader's own defs, each wrapping its dependency stubs INSIDE its own body via wrap_defs/dep_stubs_for) terminated by the run's own end marker, so a diagnosable call/var/break site is always reached either inside a module-level def's body (module_def Some) or outside every run (origin None) -- and even when def is Some, self.defs is always ModuleSource::read's own re-parse of the exact same file run_id_for interned this origin's id from, so collect_def_sites always finds the matching (name, arity, ordinal) span. Kept as a defensive fallback rather than a panic/unwrap in case that invariant is ever violated (#3085)
src/bin/succinctly/jq_runner.rs	tolerate	3691-3694	both	unreachable in a single-process run by construction: run_id_for (the sole source of an origin id) always inserts a run_origins entry for the id it hands back -- from a real load's canonical path, or its own literal-path fallback on a resolve failure -- and a def body only ever gets stamped with an origin after its module loaded successfully, so at always names a file that existed and was readable moments earlier. Reaching this arm needs that same file to vanish (or become unreadable) in the narrow window between that load and this re-read, entirely outside this process's control (#2964)
src/bin/succinctly/jq_runner.rs	tolerate	3960	both	unreachable: widening the shadow-candidate set never rejects a program the first parse accepted -- a newly covered name only wraps an already-successful dedicated parse, and a failing one would have propagated its error in the first parse too, so the retry budget is charged at the identical sites in both (#2395)
src/bin/succinctly/jq_runner.rs	tolerate	4551-4587	both	unreachable from any query this suite can build since #3457: the path walkers were the sites that panicked at MAX_NESTING_DEPTH here (sort/join/map, path()/paths/setpath/del()/assignment on a deep document), and they now return a decode-failure-tagged error, so a deep document is reported through the ordinary Err arm instead. The panic sites still in the evaluator (lazy.rs cursor_to_owned, owned_identity_recurse_step, owned_from_standard_json_at_depth, the YAML comment-preserving materialization) are not reached by a jq-mode CLI query at 250-500 levels, probed by hand; the catch is kept as the net for them and for a future guard that panics, and nesting_depth_panic_message itself is pinned by a unit test (#3457)

src/jq/eval.rs	tolerate	18081	both	unreachable: entry is one of to_entries's already-materialized {key,value} pairs, so its depth here is provably no deeper than whatever earlier check let it exist -- a document-decoded entry is already <256 deep (MAX_NESTING_DEPTH, stricter than this 384 guard), and a filter-constructed one already survived becoming a cursor via its own whole-object reindex, which is strictly deeper than any single field extracted from it could be (unwrapping only reduces depth); confirmed live, {a: (reduce range(400) as $i (0; [.]))}

src/jq/eval.rs	tolerate	40769	both	unreachable, as this arm's own comment above says: indexing or slicing a value yields zero or one result, so is_primitive never produces more than one -- kept as a named error rather than a panic.

src/jq/eval.rs	tolerate	41507	both	unreachable: a cond that flattens to no stages is . or a pipe of ., which cannot_move_register admits, so it never takes the live route (#3757); the debug_assert where stages is built fails a test build that breaks that

src/jq/resolve.rs	tolerate	2949	both	unreachable in practice today: this arm needs builtin_fallback==None (the name was never a shadow candidate) yet is_jq_builtin==true (a real jq builtin at this arity) -- every implemented builtin's own dedicated parse already lowers that shape to Expr::Builtin before resolve.rs ever runs, and #3042/#3046 closed the once-real 'unimplemented builtin' gap this existed for (see JQ_BUILTIN_ROSTER's own doc comment)
src/jq/resolve.rs	tolerate	2951	both	unreachable with the current roster: every JQ_BUILTIN_ROSTER entry of arity >= 1 already has a dedicated parser form (a matches_keyword special case or a Libm1/Libm2/Libm3::ALL entry -- confirmed by cross-referencing the full roster against both), so it is parsed straight to Expr::Builtin and never reaches here as a bare FuncCall. This arm exists for a roster name with no dedicated parse yet and a nonzero arity -- there is none today, so the loop body is reached with an empty args on every pinned-suite run (355 hits on the arm's own condition, 0 in the loop) and would only start executing if such a name were added (#2964)
