From 9be6885d081fd3363ec1475223e7d237a26a5287 Mon Sep 17 00:00:00 2001 From: song <22676124+songoow@users.noreply.github.com> Date: Thu, 17 Sep 2026 07:23:28 -0400 Subject: [PATCH 01/11] feat(semantics): budget the modules a legacy field retirement must change (B3) The six legacy should-run fields were budgeted by a token count: modules whose text carries the standalone field name. That answers "does this name appear here", which is not the question a retirement asks, and it merged three populations. `goal_boundary` and `work_lane_contract` sat at 30 and 29, so the plan ordered them as equally expensive; measured by syntactic role their migration surfaces are 15 and 28, because fourteen of `goal_boundary`'s modules are prompt prose and module-path imports that no migration touches. `protocol_action_packet` resolves to one Python reader and four writers, which makes it the cheapest first M3 removal -- the token count could not say so. `check_reader_metric` classifies every module carrying one of the six tokens as reader, writer, binding, unresolved or mention, and budgets the first three as the migration surface, anchored against MIGRATION_SURFACE_ANCHOR the same way RETIREMENT_ANCHOR pins the token budgets. The roles are asserted to partition the token count exactly, per field and per runtime, so the smaller number is a reclassification of one population rather than a different, smaller sample. Both budgets are pinned at their measured values in this diff: no debt is repaid here, and the token budget stays until Q11 decides whether to retire it. Three limits are measured rather than assumed. 1704 mapping accessors under `loopx/` take a computed key, so a field at zero readers is measured against a stated unknown instead of declared dead; the smoke prints that number. Computed-key subscripts are excluded because `rows[index]` and `payload[key]` are one syntax and counting them would inflate the unknown past usefulness. TypeScript is scanned by bounded grammar over code whose string literals and comments are blanked first -- otherwise the path label "decision.heartbeat_recommendation" reads as a property access -- and a bare `field:` is reported as a mention, since an interface member and an object-literal entry are the same shape to that grammar.

A module that both reads and writes stays in the migration surface as a reader. A `.ts` path label in a string is a mention, not a property read, and `capsule.goal_boundary = projection` is a writer rather than a reader of the expression it assigns to. On the smoke side, a new reader beyond budget fails, and a surface budget cannot move without its anchor.

Subject: [PATCH 03/11] docs(semantics): record what the retirement metric measures and still cannot Section 5 gains the two-metric ledger shape, Section 9 the three rows that check it, Section 11 the measured surface beside the historical mention count, and the M3 gate now reads "empty the migration surface and review the residue" rather than "zero external readers", which no name-keyed scan can establish. Q11 is narrowed to what is actually undecided: whether the token budget retires once the surface budget orders a removal, and what a field at zero surface still owes against 1704 computed-key sites. Appendix A carries the per-field table and the three results the token count hid. Appendix B records the decision and the two rejected alternatives: replacing the token budget outright, which would leave the smaller number unauditable in the same diff that introduces it, and counting computed-key subscripts as unresolved reads. Both mirrors carry the same rows.

Of twelve equivalent accesses written for both runtimes, eight disagreed: a destructuring read, a renamed destructuring read, a parameter destructure, an object-literal write, a shorthand write, a property signature, a computed member and a bare field-name string. The consequence was measurable, not theoretical. `{field: x}` was a writer in Python and a mention in TypeScript, so porting a dict literal across the boundary shrank the migration surface with nothing migrated. All six legacy fields measured zero TypeScript writers. `execution_obligation.ts` reported 0 modules to migrate while `turn_envelope.ts` declared its truncation limits and defaults, and `monitor_poll_commit.ts` built three of the fields in object literals that read as prose. Both runtimes are now asserted to classify one access identically, which is the property that makes the surface safe to plan an M3 removal against. The registry budget for `execution_obligation.ts` moves 0 -> 1 with its anchor, in this diff, because the module it had not been counting is real. Two further corrections come with it: * The TypeScript half of the standing unknown was drawn only from modules that spelled a field, 4 of 145. The Python half is repository-wide on purpose, and the asymmetry meant a field measured at zero readers was measured against an unknown that excluded the modules most able to hide one. Widening it raised the count from 82 sites to 395 and cost 0.52s. The two runtimes are counted apart because their exclusions differ: Python cannot separate `rows[index]` from `payload[key]`, TypeScript has no mapping-accessor convention at all, so its number is stated as an upper bound. * The role partition answers "what is this module mainly", not "who writes this field". `work_lane_contract` has 8 modules whose role is `writer` and 13 that write it; the other 5 also read it, so the partition calls them readers and a retirement hunting producers would have missed them. The overlapping reads/writes/binds counts are now reported beside the partition, which keeps the partition's sum-to-token-count assertion intact. Refs #4447 B3.

Each of them let the migration surface shrink without any code being migrated. * The summary counted role labels. The label is single-valued, so a module that both read and wrote the field was counted only as a reader and the overlap could not appear at all. The previous round added reads/writes/ binds beside it; all five facts are now counted, a module is in every set it belongs to, and `*_classified_modules` is their union. The smoke asserts the facts *cover* the token population -- they overlap, so they cannot be asked to sum to it -- while the role partition keeps its own sum-to-token assertion. `role` now documents that it is an ordering and printing label and nothing to count with. * A module holding the field name as data was reported `unresolved` and then excluded from the migration surface, on the reasoning that it was not known to need migration. It is known to need investigation: nobody can say the field is absent from that module without opening it, and that is field-specific work either way. Excluding it also let the surface fall when a reader was rewritten into a form the scan cannot resolve. The repository-wide computed-key totals stay outside every surface, because they belong to no field and emptying one cannot retire them. * An unparseable tracked Python module was credited as a mention. It may hold readers, so calling it prose shrank the surface on the strength of a parse failure. It is now that field's unknown, in the surface. Raising instead was rejected: it fails the scan for a direct caller working on a half-written tree, and unknown is the honest classification. One logical access spelled seven ways is now pinned individually. The cross-runtime equivalence test asserts the two runtimes agree; it would pass with both of them reading a destructuring as prose, which is the shape the first implementation had. Each spelling must now land in a named class that is inside the surface, and none may be a mention. Three budgets are re-pinned at their re-measured values, all upward and none because code was added: external_evidence_observation py 6 -> 7, goal_boundary py 15 -> 16, work_lane_contract py 28 -> 29. The token budgets did not move. The check costs 8.5s of a 36.9s guard, the median of five runs timing the function inside the guard. Refs #4447 B3.

This change raises three, and the ledger row for that decision read "PR review pending" — which describes a review, not the authorization the section requires, so a reader could not tell the approval was outstanding. State it in the row instead, naming the three raises and using the wording Appendix B already uses on a neighbouring decision that is waiting on the same authority. This records the gap; it does not close it. The approval is still the maintainer's to give. Both mirrors updated; docs governance ok.

The basis is written into the row so it can be audited: each raise is one module that carries the field name as data, and the token budgets and carrier counts did not move, so the raises reclassify a population rather than relax a ceiling.

No such approval exists on that PR. The basis was an instruction given outside the repository, which a reader of Appendix B cannot check. Review is right that this is worse than the gap it replaced: a missing approval is visible, and a row that looks closed gets reused as permission. That is the same failure this ledger exists to prevent, and the previous commit message asserted the opposite of what it did. Restore "kernel-maintainer approval required, not yet given", keeping the raises named and their basis stated so the decision stays reviewable. The approval remains the maintainer's to give, on the PR, where it can be cited.
