TML-3483. Related: TML-3020 (the eleven older duplicated numbers, not touched here).

Summary

main had three files named ADR 258 - …, so "see ADR 258" did not say which decision it meant:

ADR 258 - List cardinality has independent container and element nullability.md
ADR 258 - A model names its storage verbatim, and a rename is an operation.md
ADR 258 - A collection keeps its class through the chain.md

The same happened to 207, 255 and 259 in the last two weeks. The ADR that merged first keeps the number. Each ADR that merged later moves to a new number:

Was Now ADR
255 262 Block specs bind top-level block values
207 263 A serverless Postgres connection has the same query interface as a postgres() client
258 264 A model names its storage verbatim, and a rename is an operation
258 265 A collection keeps its class through the chain
259 266 The cache middleware passes data to its store, and the store decides how to cache

The new numbers start at 262 because main now has ADR 260 and open pull requests already use 256 and 261.

The query fragments ADR (259) cited "ADR 260" for the collection-scopes ADR in #30428, which has not merged. ADR 260 on main is now the afterTransaction stage, so that citation is removed. #30428 can add it back with its final number.

Every link and every mention of a moved ADR in docs, package READMEs and project files now uses the new number. Mentions in project research notes that describe the numbering at an earlier point in time are left as they were. ADR-INDEX.md gains rows for three ADRs it was missing: 259 (query fragments), 264 (storage names) and 265 (collection class).

Open pull requests this affects

These pull requests change a file that moves here. Git should carry their changes to the new file name, but links they add to the old name need updating:

These open pull requests add an ADR whose number is already taken, so they clash again when they merge:

Testing performed

  • Checked every Markdown link in the changed files that points to an ADR. All resolve. Two links that were already broken on main (ADR 009 and ADR 015) are unrelated and unchanged.
  • Searched the repository for the old file names and the old numbers. The only remaining matches are the earlier-point-in-time research notes described above.

Skill update

n/a — internal only.

Upgrade instructions

upgrade-instructions/pending/adr-numbers-unique/extension/ declares changes: []. The three package READMEs change only their ADR links, so extension authors have nothing to do.

Checklist

  • All commits are signed off (git commit -s) per the DCO.
  • I read CONTRIBUTING.md and the change is scoped to one logical concern.
  • Tests are updated (or n/a if the change is doc-only / refactor with no behavioural delta). n/a, docs only.
  • The PR title is in TML-NNNN: <sentence-case title> form.
  • The Skill update section above is filled in.

Notes for the reviewer

Alternatives considered:

  • Move whichever ADR has fewer references. For 255 that would move relation ordering instead of block specs, and no open pull request touches it. Rejected because a rule based on merge order is simple to apply the next time, and an earlier fix (ADR 255 to ADR 256 for mutation-default generators) already moved the later ADR.
  • Also renumber the eleven older duplicates (159 to 224). They have been cited by number for months, and deciding which ADR each bare mention means needs reading each citation. That stays with TML-3020.

Agent: etain-65

Summary by CodeRabbit

  • Documentation
    • Updated ADR references across guides, architecture documentation, and package READMEs to reflect current numbering.
    • Added ADRs to the architecture index and corrected links covering serverless PostgreSQL connections, block specifications, storage naming, query collections, and cache middleware.

Five ADRs shared a number with an ADR that merged before them. Each
later one moves to a number no file or open pull request uses:

- ADR 255 Block specs bind top-level block values -> ADR 262
- ADR 207 A serverless Postgres connection ... -> ADR 263
- ADR 258 A model names its storage verbatim ... -> ADR 264
- ADR 258 A collection keeps its class through the chain -> ADR 265
- ADR 259 The cache middleware passes data to its store ... -> ADR 266

Links and mentions are updated. The ADR index gains the three ADRs it
was missing (259, 264, 265).

📝 Walkthrough

Walkthrough

The documentation adds ADR index entries, renumbers ADRs, and updates related ADR references. The described interfaces and behaviors remain unchanged.

Changes

ADR documentation updates

Layer / File(s) Summary
Update ADR index and identifiers
docs/architecture docs/ADR-INDEX.md, docs/architecture docs/adrs/*
The index adds entries for ADRs 262, 264, 259, and 265, and updates several identifiers. Five ADR headings are renumbered.
Update block-spec references
docs/architecture docs/adrs/ADR 126 - PSL top-level block SPI.md, docs/architecture docs/adrs/ADR 231 - Declarative attribute specifications.md, docs/architecture docs/adrs/ADR 246 - Option arguments and select templates for authoring helpers.md, docs/architecture docs/adrs/ADR 249 - Central attribute-spec registry.md, packages/1-framework/2-authoring/psl-parser/README.md
References to the block-spec ADR change from ADR 255 to ADR 262.
Update other ADR references
docs/Serverless Deployment Guide.md, docs/architecture docs/adrs/ADR 259 - Query fragments are functions.md, docs/architecture docs/subsystems/*, packages/3-extensions/*/README.md, upgrade-instructions/pending/adr-numbers-unique/extension/instructions.md
Serverless, query, storage, collection, migration, and cache documentation references change to the corresponding ADR identifiers. The pending extension instruction file gains YAML front matter with an empty changes list.

Merge Risk: 🔵 Low · up to 203ff

The ADR links now resolve, but five existing records were renumbered under append-only guidance. Runtime behavior is unaffected; confirm and document the exception or accept the governance deviation before merging.

  • observed — packages/1-framework (library) was modified; 1 changed file maps to changed impact.
  • observed — upgrade-instructions (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in docs/Serverless Deployment Guide.md: Updated both ADR references in the factory comparison discussion from ADR 207 to ADR 263; the described connection interface, type compatibility, and per-request lifecycle remain unchanged.
  • observed — Modified behavior in docs/Serverless Deployment Guide.md: Replaced the ADR 207 link with ADR 263 and changed the ADR 159 lifecycle note to attribute the contrast between connection timing to ADR 263 instead of ADR 207.
  • observed — Modified behavior in docs/architecture docs/ADR-INDEX.md: Added ADR 262 on typed top-level block specs and ADR 264 on verbatim model storage names and explicit rename operations. ADR 262 replaces the prior ADR 255 block-spec entry; ADR 257 and 258 remain listed.
  • observed — Modified behavior in docs/architecture docs/ADR-INDEX.md: Added entries for ADR 259 query fragments as functions and ADR 265 collection subclass preservation through SQL ORM query chains.
