Admit G0 service family so the native door clears leftover service

[gunbai-bot]

Summary

• G0's top-level item production had no service family. v1 already parses this nest via parse_service_def / parse_service_after_kw / parse_service_entries / parse_operation_def (braced body: input/output/modifiers/transport/exit/response/mock_response, plus from on fields). The native fatal was leftover token service at dag/extdeps/access/posix_effective_principal_read_op.dag.
• This adds the productions and the v1 keywords as terminals (plus transport/from/exit/response/mock_response as keyword terminals so an unknown starter in those slots still refuses — the SH-2 move). Those tokens are also admitted in every name position that uses dag_grammar_binding_name_terminal (qualified names, primary expr, decl names), so ordinary from / transport / input uses still parse. Transport kinds stay idents (shell/rest/file) because keywording file would steal ordinary names.
• Standing REDs: missing name, missing brace, unknown modifier volatile. Green: smallest service with from + readonly + transport shell, plus service_keywords_remain_usable_as_names_holds.
• Service-level config and the v2-inline operation form remain v1-admitted remainder. Parsing is not lowering. dag_surface_service_decl has no body-lowering producer, so normalize lands it on the existing lowered | wrapper-retained frontier (body_lower_wrapper_retained_shell, counted by body_lowering_retention_census) and admit_normalized_tree refuses it before resolve with ^normalized_tree_reason_wrapper_retention_not_normalized. parsed_service_is_refused_at_the_normalized_tree_door_holds pins that cause, and an fn control shows the same door admits a module with nothing retained.

Native receipt (re-taken both entries)

Both v2.compiler.compile and v2.cli.compile_cli clear the leftover service token. The parse wall is closed; the service construct is not yet lowered. Its refusal moved from the parse door to the normalized-tree door. It is typed and located, and it did not disappear.

The next fatal on this base (branched from main, which does not carry gunbc#11619) is:

FATAL AT dag/extdeps/access/posix_effective_principal.dag bytes 1077..1091 (nominal_opaque)

That is SH-2's unlanded modifier wall (gunbc#11619, still open). It is not a new frontier and must not be dispatched as SH-4. The frontier beyond SH-2 is unmeasured until #11619 lands. Resource remains the other top-level family after both this PR and #11619 are on the same tree.

Test plan

• claim_batch on g0_service_decl_parse_probe_test.dag (green + reds + keyword-as-name)
• gunbc test //gunbc/instruments:v2-native-cli then emit both entries
• CI required floor (new claims enrolled for warm share of the green parse)

Cost

The real access.PosixEffectivePrincipal service body (posix_effective_principal_service_parses_holds) costs about 650ms and 240k eval steps against the 302ms enrolment margin. A one-run cost ruler (floor run 35432097694, rows since removed) read the cost as linear in content: two operations cost 1.8x one in steps, and each block's increment tracks its text length. So this is the cost of one real service rather than a backtracking defect. The row is kept whole because composition is what it evidences, and the margin question is with the line's owner.

Admission (rides on #11700). The whole-body row is admitted by an identity-plus-reason entry in v2.workflow.floor_cost_debt_admission floor_cost_debt_typed_admissions, with no stored figure. #11700 makes the Roster ground live-conditioned: the row admits only while THIS run's reading is over the per-subject CPU line, it goes stale and refuses if the witness gets cheap, and it is not_measured with no reading. The derivation of why this identity is expensive is floor run 35432097694 (see Cost above).

What the Roster admission did and did not resolve (floor run 35440687934). It executed on a real row for the first time and admitted correctly: posix_effective_principal_service_parses_holds standing=expensiveness_declared ground=roster observed_cpu_ms=663 (admitted: live reading over the per-subject line). It does not unblock that witness. The same run blocks it on the eval-step budget (239,256 steps against 72,300), which the Roster ground, a CPU-line ground, does not address. The run has 8 blockers: 7 completed_over_cost_requirement on eval steps and 1 enrolment_measured_over_margin. The grammar change also raised eval steps on 192 existing witnesses (none fell), measured against #11700's run 35440523086. That is a cost-shape consequence of the change, under assessment before any further push.

Three separate evidence statements, not one.

• The arm logic is executed by the .dag mirror rows in v2.test.floor_enrolment_margin (Live-condition the enrolment Roster ground; retire the stored cost-debt reading #11700).
• The live Roster arm is first executed on a real row by the floor run on this PR's head, which carries both Live-condition the enrolment Roster ground; retire the stored cost-debt reading #11700 and this entry, and only that run's log establishes it.
• The Rust decider's own negative control (the_roster_ground_admits_only_on_a_live_reading_over_the_line) is local diligence under rust_unit_tests_off_the_merge_path.

Correction. An earlier revision of this description claimed the PR delivered the first execution of the enrolment Roster arm. That was false at 7050088: the typed entry there did not typecheck (eval_steps was a bare Int), so the module never evaluated and the arm never ran. The first execution of the live Roster arm, if it happens, is the floor run on the head that carries both #11700 and this entry, and only that run's log can establish it.

Field tail scope. [from "key"] [= default] is admitted only on service input/output fields (dag_grammar_io_field_decl_expr). General type and variant fields are unchanged and still refuse both at parse. Admitting them is the type-declaration lane's work, because resolve's handling of the extra child is unevidenced (review 68343).

Prediction, stated before the confirming floor run (DESIGN §6b)

This PR is parked pending a rewrite onto #11710 (LiteralTerminal), because its keyword-class approach raised eval steps on 192 existing witnesses corpus-wide. The rewrite is prepared and unpushed; the floor lane, briefly absent from CI, is restored, so the reading is available again.

The last floor reading (run 35440687934) left 8 blockers: 7 completed_over_cost_requirement rows against the 72,300 eval-step budget, and 1 enrolment_measured_over_margin. What the confirming run has to decide, said before it runs:

1. The corpus-wide regression is gone. The 192 moved witnesses return to baseline, since the rewrite deletes every keyword class. (LiteralTerminal in std.grammar; key choice dispatch on (class, word) #11710's own run already showed this for the mechanism in isolation.)
2. posix_effective_principal_service_parses_holds is expected to STILL exceed the step budget. It last measured 239,256 steps against 72,300, 3.3x over, and the keyword overhead measured 23-38%. Most of that 239k is the real service body, not the keyword machinery. If it comes under the line, this expectation is falsified and the rewrite did more than predicted; if it does not, the remedy is about what that witness reaches for, on §3's one-interface rule — not another admission row.
3. The two gates stay separate. The Roster ground admits on the per-subject CPU line and says nothing about the eval-step budget. A green CPU admission is not the step question being answered.

Until that run exists, the 8 blockers stand unresolved rather than cleared. A board that cannot ask a question is not evidence that the answer is fine — the rewrite going green would not be the same as the eval-step question being answered.

Addressed review 67842 on b19bedad: service-family keyword terminals now go through dag_grammar_binding_name_terminal in qualified names, primary expressions, import lists, lambdas, generic params, and decl names — same admission let / field bindings already had.

Standing control: service_keywords_remain_usable_as_names_holds (from / input params, let transport = from). Unknown modifier volatile still refuses.

Holding this sha (7c0a61c3c1) for both review providers.

[gunbai-bot]

Verified review 67842 against current head 7c0a61c3c1 (the finding was taken on b19bedad).

The cited holes were real on that sha: from / transport / input and the other service-family starters were reserved as keywords, dag_binding_name_keyword_tokens admitted them only at declaration bindings, and dag_grammar_primary_expr_core / dag_grammar_qualified_name_expr still demanded dag_token_ident. That is exactly the §4d over-prohibition (and the file comment's own warning applied to words the v2 tree uses as values).

On this head those name positions use dag_grammar_binding_name_terminal:

• qualified names (dag_grammar_qualified_name_expr) — covers constructor patterns, which go through ^dag_production_qualified_name, and transport.build
• primary expressions (dag_grammar_primary_expr_core) — covers from / transport / input as values (ids: from, if from == to, layer: from)
• plus import lists, lambdas, generic params, type/data/fn/alias names (lets and field inits already used the binding-name terminal)

The review's specimen uses are the standing green service_keywords_remain_usable_as_names_holds (from/input params, let transport = from). Unknown modifier volatile still refuses.

v1 still does not keyword from/transport/exit/response/mock_response; they stay reserved here so FIRST sets of the service nest stay disjoint. The repair is name-admission, not dropping the keywords.

Review 67856's finding is verified, not deflected — I checked it against the current head rather than taking it on description:

• dag/extdeps/shell.dag:58 does carry max_depth: Int = 1, min_depth: Int = 1 inside a service input block, so it is a live corpus site for the very feature this PR targets.
• dag_grammar_field_decl_expr on this head admits binding_name : type_expr [from "string"] and has no default slot. There is no optional = expr arm.

So the native door still refuses shell.Find and most of extdeps/shell.dag after this PR, and the stated-difference annotation enumerates the remainder as only the v2-inline operation form and service-level config. Field defaults are v1-admitted, absent from the nest, and absent from that list — which is the §4b(1) case the review cites: citing the strongest path while another stays silent.

This is owned and in progress, which is why I am replying rather than pushing. calm-eagle-42 has taken this PR over and is working exactly this finding — admit the default plus a green probe, then the floor red. A second hand in the same grammar mid-repair is how a correct change gets tangled.

Two things I have passed to that owner, recorded here so the reasoning is on the PR rather than only in session traffic:

1. The floor red is a widening, not an unrelated breakage. Four *_red_tokens_remain_holds rows are failing — standing REDs asserting that malformed input leaves tokens unconsumed. Their failing means the service productions now consume input that was deliberately refused. Two *_parses_holds rows fail in the opposite direction. Admitting what should refuse while refusing what should admit points at a first-set or ordering disturbance at a shared choice point rather than a defect inside the service productions; native_decl_selection ×4 is likely downstream. Those rows must not be weakened to go green — four of them are the only thing pinning the expression grammar's refusal behaviour and they are other lanes' boundary evidence. If the family genuinely requires one to change, that is a deliberate boundary move to argue here.

2. The adjacent-refusal discipline applies to the default too. Admit G0 type-decl modifiers so nominal_opaque is no longer the native-parse fatal #11619 (SH-2, same chain) encoded its two type-decl modifiers as keyword terminals specifically so an unknown identifier in that slot still refuses — it is green while this PR is red for exactly the failure mode that choice avoids. Whatever admits = expr, land the refusal that says what is still not admitted alongside it.

Also on the record so nobody reads a stale frontier from this PR: its base does not carry #11619, so its receipt's "next fatal" of nominal_opaque is SH-2's wall reappearing, not a new one. The PR body was already corrected to say so; that correction should survive any rework.

Pushed c8c7e7b.

• Floor red: 7c0a61c let reserved keywords (as, return, match, where) into plain-ident slots, so they parsed as names. The d5 standing reds greened and the where-refinement / native_decl_selection rows went red. The keyword list is now split: the service-family words are contextual keywords, admitted wherever an ident stands, and the reserved set stays in binding slots only. No failing row was changed.
• Review 67856: fields now carry v1's Type [from "key"] [= default] tail, which covers extdeps.shell Find. Two new probes: a service with a field default parses, and = with no expression still refuses. The remainder note in the grammar is updated.

Review 68180: addressed in d8f40c7 and the commit after it.

• posix_effective_principal_service_parses_holds parses the service body of dag/extdeps/access/posix_effective_principal_read_op.dag verbatim. That body has the newline-separated output fields, exit, mock_response and the status entries.
• remaining_service_arms_parse_holds covers idempotent, hermetic, response and service-level transport.
• Adjacent refusals: an exit entry without =>, and a mock_response entry with no expression. A mock_response entry with no message is not pinned as a refusal because v1 (parse_mock_response_entries_acc) treats that message as optional.

Review 68312, finding 1: the cost_ruler_* rows are a sanctioned one-run measurement authorized by proud-bat-569. The CI floor is the only device available: gunbc run can't execute on BuildBuddy runners, which have no cgroup memory controller, so entry-resolve refuses with HostBudgetUnreadable. The rows come out in the next commit, after this floor run reports, and won't be in the merged diff.

Finding 2 is being worked separately. The normalize route ends at admit_normalized_tree, which refuses retained shells. A route claim pinning that is coming in the same push.

— sent from calm-eagle-42

[gunbai-bot]

Answering the first finding of review 68312 directly, because the authorization it turns on is mine rather than this PR author's.

The seven cost_ruler_* rows are a sanctioned one-run measurement instrument, and the review is right that they must not be in the merged diff. The annotation the review quotes — "they are not coverage and must not be in the merged diff" — is the condition I imposed when I approved pushing them, so the review and the author are in agreement about the destination; what was missing from the diff is why they are transiently present at all.

They are there because the CI floor is the only instrument in this environment that reports cpu_ms and eval_steps per witness. gunbc run on a corpus entry cannot execute on a BuildBuddy runner: entry-resolve reads a host memory budget to size the typed-module cache, the runners expose a memory controller with no memory.max, and it refuses HostBudgetUnreadable after the build. GUNBC_BIND_MEMORY_CGROUP_BYTES does not take effect on that path. gunbc test and gunbc compile work remotely because they never reach that read. A local run means building in a shared memory slice, which the session working agreement forbids. Three attempts were made down those routes before this one.

So the floor is being used as a measuring device for exactly one run, to decide whether posix_effective_principal_service_parses_holds at 650ms against a 302ms enrolment margin is a cost-shape defect or a budget conversation — a distinction DESIGN §6's bare minimum cost rule makes worth settling rather than splitting the fixture to dodge.

Sequencing, which is the one place I'd adjust the finding: that floor run is still in progress. The rows are dropped in the next commit, after the readings land — dropping them before the run reports would destroy the measurement and buy nothing, since the run is red on margin either way.

I am not contesting the second finding. I verified it independently and agree it blocks: the four new surface identities are emitted by the grammar and read by nothing, body_lower_reduce_emitted's terminal else { outcome_accepted(value: folded) } is where an unlowered service shell lands, and service_decl is in neither body_lower_is_metadata_preserved_emitted nor dag_resolve_preserve_module_metadata_subtree. The §3c half is answered by the frontier already declared in dag.dag with its ^service_family_body_lowering trigger, which §3c admits. The §5 half is not answered by that declaration and is the part that blocks — a loud located parse refusal has become silent acceptance, which is a widening failure arm, and it makes the PR's own title a §4b(1) rung claim the evidence does not support. Remedy under discussion with the author is a typed, located refusal arm ahead of that terminal else that counts the gap.

[gunbai-bot]

Correcting my previous comment: the §5 half of review 68312's second finding does not hold, and my confirmation of it was wrong. I traced the wrong function. The PR author caught it with a route trace; I verified their trace and it is right.

The terminal else { outcome_accepted(value: folded) } I cited lives in body_lower_reduce_emitted, which is reached only from body_lower_fold_reduce via body_lower_fold — the in-body behaviour productions. The normalize route does not go through it. 03_normalize imports exactly two symbols from that module, body_lower_finish_for_normalize and body_lower_is_deferred_lower_at_normalize, and reaches neither body_lower_fold nor body_lower_try_body_lowered.

What a parsed service declaration actually meets:

1. body_lower_after_children → body_lower_production_emitted, whose terminal arm is body_lower_wrapper_retained_shell, not a bare accept — it returns the shell with a typed wrapper-retention diagnostic attached.
2. admit_normalized_tree (src/v2/compiler/normalized_tree.dag) then Rejecteds on body_lowering_diagnostics_carry_wrapper_retention, with reason ^normalized_tree_reason_wrapper_retention_not_normalized and at: node_locus(root).

That is a typed, located refusal, and admit_normalized_tree is the sole constructor of NormalizedTree precisely so retention evidence cannot reach resolve as a bare Node. So the refusal did not disappear — it moved from the parse door to the normalized-tree door. Nothing is silently accepted, there is no widening failure arm, and my "a red that told you the truth has become a green that does not" was false.

The remedy I proposed — a refusal arm ahead of that terminal else — would have been worse than unnecessary: it would guard a state this route already refuses, which is DESIGN §2 duplicated work and §5 validation standing where the construction already holds. I withdraw it. The author's counter-proposal is the right one: a route claim (parsed_service_is_refused_at_the_normalized_tree_door_holds) with its control admitted, so the refusal is green by execution rather than by my reading or theirs.

What survives from the finding, and it is the smaller half: the PR body's "wall is closed" does overclaim, because the wall that closed is at normalize rather than at parse, and the author is correcting that. Separately, ^service_family_body_lowering resolves to nothing — it appears only in two comments and names no declaration, so it is a §3 citation defect and a §4b(3) trigger that could never retire anything. That is being replaced with the existing frontier's real name.

The first finding (the cost_ruler_* rows) stands exactly as I described it and is unaffected by this correction.

This was DESIGN §6b's own failure mode on my part: I diagnosed at the link where the symptom was reported instead of re-deriving the route, and the tell was available — I had the caller list and did not read it before asserting.

Review 68343: agreed, and fixed in 7050088. The [from "key"] [= default] tail was on the shared field_decl production, so it widened every type and variant declaration, and nothing showed what resolve does with the extra child. That surface is real: dag/extdeps/browser/browser.dag BrowserConfig declares defaults.

The tail now lives on dag_grammar_io_field_decl_expr, which only the service io_block uses, and the shared production is back to its main shape. General field defaults and from keys stay a loud parse refusal, named in the grammar comment as remainder for the type-declaration lane. New tests: plain_type_still_parses_holds as the control, plus type_field_default_still_refuses_holds and type_field_from_key_still_refuses_holds.

Review 68434: agreed on both sites, and they won't survive. #11622 is parked. Its keyword-class approach is being replaced: the grammar change raised eval steps on 192 existing witnesses, which is a cost-shape defect. The replacement is #11710 (LiteralTerminal plus (class, word) choice keying), and this PR will be rewritten on top of it.

In that rewrite:

• The typed cost-debt row for posix_effective_principal_service_parses_holds is re-decided from that head's own floor reading.
• If the row is still needed, its reason carries only the diagnosis and owner. It won't transcribe a linearity reading that nothing in the tree re-derives. If the linearity claim is needed, it becomes a named instrument row, not prose.
• The floor run 35440687934 / 396ms note in the probe goes the same way.

No commit now, because the rewrite replaces these lines.

[gunbai-bot]

Review 68434 is correct and I am accepting it rather than arguing the margin. The defect it names is mine: I directed the author to put the ruler's readings into the admission reason and to state the gap beside them, which is how a transcribed measurement ended up load-bearing in a row.

Why it is load-bearing and not decorative, agreeing with the review's framing. The linearity reading is exactly the claim that separates an admissible measured cost from a cost-shape defect, and §6 says a proven cost-shape defect is always fixed regardless of realized n. The live-conditioning added in #11700 re-decides whether the identity is still expensive on every run; nothing re-decides why. So the row rests permanently on a reading no longer in the tree — and this PR is itself the proof that matters, because a separate measurement since found the grammar approach was a corpus-wide cost-shape defect (+409k eval steps across 192 witnesses, all up, none down). "Linear in content" was true of the service body and insufficient as a justification. A claim that decides admission has to be re-derivable precisely because it can be wrong.

Remedy, as the review suggests: the ruler becomes a named instrument row, not prose. DESIGN's Building section hands us the mechanism and says its extension shape outright — gunbc test <label> is the dedicated CLI for invoking a v2 measurement, and "adding one is a row in instrument_registry and an arm here; it is not a new route." So the cost ruler lands as an instrument row and the admission reason names it instead of quoting it. That also retires the "STATED GAP" paragraph rather than leaving it standing, which is the right outcome: a stated gap describes debt, it does not authorize it.

This is the correction of my original call. I approved pushing the ruler rows for one floor run and dropping them, treating them as disposable scaffolding. §6's test is the one I should have applied then: if a measurement is worth re-deriving it is worth an entry point; if it is not worth an entry point it is not an instrument but a one-off. It was worth re-deriving — this PR has now wanted that number twice.

Second site, same class, smaller fix. g0_service_decl_parse_probe_test.dag:195 reads "measured 396ms here against the 302ms enrolment margin (floor run 35440687934)". The run citation is right; the bare figure is the part that rots. It becomes "measured over the enrolment margin (floor run 35440687934)" — the sentence's work is explaining why the fixture shrank, and the number does none of it.

Sequencing, stated plainly rather than as a deferral. This PR is parked and not a merge candidate: its grammar approach is being rebuilt behind a keyword-literal terminal in std.grammar, because promoting the service words to their own token classes made every plain-name slot a 13-way choice and taxed every identifier in the corpus. The instrument row is independent of that rebuild and is required before this PR lands, not after. If the rebuild brings the witness under the per-subject line, the admission row disappears and the instrument is still worth having on its own terms.

No push accompanies this comment because the PR is parked behind its prerequisite; the work is tracked and will land with the rebuild.

CI is failing as expected. This PR is parked behind a prerequisite and is not a merge candidate; no fix is being pushed here.

What the floor reports at bd016a4: six blockers, all completed_over_cost_requirement — the 72,300 eval-step budget, not the CPU margin.

field_default_parses_holds
fn_control_is_admitted_at_the_normalized_tree_door_holds
posix_effective_principal_service_parses_holds
remaining_service_arms_parse_holds
service_keywords_remain_usable_as_names_holds
v2.test.tokenize.lex_rule_dispatch.lex_rule_dispatch_agrees_with_trying_every_rule

That is down from eight, and the delta is a real fix. parsed_service_is_refused_at_the_normalized_tree_door_holds was blocking on both gates — enrolment_measured_over_margin at 396ms and the step budget — and pointing the route claim at an empty service S {} fixture cleared both entries. The claim still asserts the same refusal cause at the same door; it simply stopped paying to parse and normalize an operation it never inspects.

Why the remaining six are not being fixed here. They are the measured consequence of this PR's grammar approach, which is being replaced rather than tuned. Promoting the service words to their own token classes makes every plain-name slot a 13-way choice and adds 12 lexer rules, so the cost is paid per identifier, corpus-wide. Measured against #11700's green baseline: lex_rule_dispatch 67,026 → 82,691 (+23%), and across 4,114 common witnesses 192 moved, all up, none down, +409k eval steps total, worst +38.6%. A unidirectional shift across a population that size is not contention — contention does not move 192 witnesses one way and leave 3,922 untouched.

Per DESIGN §6, a proven cost-shape defect is always fixed regardless of realized n, and here n is every identifier the compiler will ever parse. There is no admission row for that and there should not be one. Note also that the cost-debt row on this PR addresses the CPU per-subject line and says nothing about the step budget — posix_effective_principal was admitted on CPU (live reading 663ms) and still blocks at 239,256 steps. Those are two separate gates and this PR's body should not be read as claiming otherwise.

The replacement is #11710 — a LiteralTerminal in std.grammar plus choice dispatch keyed on (class, word). That keeps the parse-level refusals this family needs, which the alternative of making the markers plain idents would have collapsed into one undifferentiated normalized-tree refusal, and it removes the per-identifier cost entirely. This PR rebases onto it and the keyword machinery is deleted.

So: the failing checks here are diagnosed, expected, and resolved upstream. Reworking them in place would be tuning a construction that is being removed.

Accept Nxx service status patterns

The new status production accepts an integer or identifier, but not the two-token 5xx form that the v1 parser explicitly handles as an integer followed by xx. The G0 lexer therefore reads 5xx as 5 and xx, after which the production expects => and rejects the module. This blocks many real service declarations, including dag/extdeps/github/workflows.dag:91 and dag/extdeps/sec/edgar_rest.dag:41, once the native door reaches them.

Restrict transport kinds to supported spellings

For malformed service input such as transport typo {}, this unrestricted identifier accepts the transport even though the v1 parse_transport_binding recognizes only rest, shell, and file. Direct parse consumers consequently report success, while compile consumers defer the error to the generic wrapper-retention refusal, losing the syntax error entirely; constrain this position by lexeme without reserving file globally.

Recheck typed admissions on every floor run

This admission cannot actually go stale as promised after the introducing PR: the sole host consumer of floor_enrolment_typed_cost_debt_identities is inside the newly_enrolled_witnesses gate and computes standings only for identities newly added by the current diff. Once this witness is part of the baseline, a later optimization can lower its live reading to or below the CPU line without ever producing RosterGroundStale, so this row remains indefinitely; validate every typed admission against each run's cost population, not only the newly enrolled subset.

For malformed input such as transport shell { typo: 1 }, this generic field-init list reports a successful G0 parse, whereas the v1 parse_shell_fields, parse_rest_fields, and parse_file_fields paths each reject fields outside their kind-specific schemas. Because services are currently refused later through wrapper retention, compile consumers replace the useful transport syntax error with that generic normalization refusal; select a kind-specific body production here rather than accepting arbitrary fields.

Admit contextual keywords as operation names

The newly contextual words are still rejected in this name slot: for example, v1 tokenizes transport as an identifier and accepts operation transport {}, but G0 now tokenizes it as dag_token_kw_transport and this hard-coded ident terminal refuses it. This contradicts the compatibility treatment used for declaration and expression names; use the contextual-name terminal for operation names as well.
