* feat(environment): explain values an application derives from other fields
Prompt-built environments withheld creates whose responses carry values the
application derives deterministically, which the write model kept as
constants or could not match across calls:
- A composed string is literal text plus parts read from the fields other
rules write: a field's value, its slug, or a clock's calendar digits. A
create composes a string only when another entity of the type spells it
the same way and none spells it otherwise, and never from two sources
serving could tell apart; an update composes an unsent change from members
stored as sent and unchanged fields that also spell its value before the
call. A composed field no longer pins the members it reads.
- A trimmed clock format drops trailing fraction zeros, as Go spells
nanoseconds. It is learned from the type's values, a later create or a
later update, and spreads to the plan's other clocks unless a value shows
a fixed width.
- A large integer no entity of the type holds, among distinct ones of the
same length and kind, is a generated unique value, served as a seeded
integer.

* fix(environment): keep clock spellings, linked ids and word boundaries honest
- A later update's clocks take the plan's spelling, sibling-trimmed
clocks included, wherever the call's values fit it, so an update whose
later call trims only one of two clocks is served.
- A held value that ends its fraction in a zero keeps a create's clock
at a fixed width, whatever order the held spellings come in.
- A large integer that another field of the created entity also holds
is linked, as a repeated token is: it is never unique, and the create
is withheld as unexplained-change.
- Composed parts are delimited by whole characters through the shared
joinsBefore/joinsAfter, so an astral letter joins a match to its word.

* test(environment): keep a same-width fixed clock out of trimming
A held .123456780 beside a held .12345678 keeps the create's clock at
nine digits in either order; the cases fail on 8ce1127b5.

* fix(environment): check composed parts and clock fits before they shape a plan
- A composed string whose part has nothing to spell refuses the create
or update through the apply Result instead of keeping a stale value.
- A composition learned on a later call is rebuilt from each earlier
call's fields, so an earlier call that left the value otherwise
contradicts it.
- An update adopts its fitted clock spellings only after the
unknown-entity and contradiction checks, so a call on an entity an
unmodelled write left unknown no longer trims a served plan's clock.
- Sibling trimming on a later create also checks that call's fields,
so a sibling clock it shows with a trailing zero stays fixed-width.

* test(environment): split the derived-values view tests by rule

* fix(environment): keep fixed-width, zone and generated-integer evidence through a plan
- A plan keeps the first value that showed each clock at a fixed width,
from held entities and every accepted create or update. No later fit
or sibling trim widens that field, and a later call that shows it
shorter is withheld.
- Two stamped clocks are one composed source only when they share a
zone offset. A held entity that holds the target field as anything
the parts do not spell, a non-string included, vetoes the
composition. The token index is built once, and only when a string is
left to compose.
- A generated integer that another field repeats as a number at any
depth is linked. Compare treats two integers of one JSON kind and
length under a unique rule as generated values.

* test(setup): share registration prewarm host preparation
* fix(environment): retain write evidence and match trimmed response clocks
* fix(environment): withhold creates whose generated integer another string repeats
A unique integer whose digits show in another top-level string that no
template or composed rule rebuilds from it (an echoed serialText, or a
token like folder-<id>) withholds the create as unexplained-change,
since serving would seed the integer and keep the string. A templated
copy is still served.

* fix(environment): hold later creates and compare to the composed and integer forms
- A later create whose response spells a composed field otherwise than
the plan rebuilds it is withheld as unexplained-change.
- A unique field learned from a generated integer accepts only an
integer of the same length and kind from a later create, as serving
seeds one.
- Compare counts a composed field as equal when each side's response
spells it from its own fields, which compare under their own rules.

Verification
Executed on macOS with Node v24.22.1 at a1edeafd (main 79845063 plus this branch). The prompt-built recordings and
evaluations used a local, unpushed build of this branch merged with the scenario-timing branch (#6967), whose request
times the clock rules need from browser scenarios, on Ubuntu 24.04 VMs with snap Chromium 155. The baseline is the same
merge without this branch.
Gates
Follow-up on 2026-10-25, after merging main a5bfd0440, with Node 24.22.1 and npm 11.16.0 on macOS:
- Environment write/compare source tests: 26 files, 839 passed.
- Analysis-view CLI/MCP, environment served-write MCP, environment-compare CLI, managed bundle read guards, and setup registration prewarm boundaries: 6 distinct files, 77 passed. The managed low-headroom failure is fixed by main's Evidence ownership change (#7036); the setup tests share host preparation to satisfy lint without removing cases.
check:fast,format:check, anddocs:check: passed.- New capture-to-plan regressions reproduce missing composition parts on earlier updates (null and structured sources) and fixed-width clock evidence from either the selected entity or another held entity. Rule tests exercise several separator/zone groups in both orders, choosing each group's widest trimmed peer while preserving fixed-width fields.
- Compare uses the domain clock matcher on parsed readings. Tests cover shorter fractions, absent fractions, maximum width, trailing zeros, separators, zones, and response-entity scope; the compiled CLI accepts a Go-style create whose live clocks have eight digits and served clocks have none, preserving all input Evidence files.
- The original application's recordings and model evaluations below were not rerun in this follow-up.
Original author validation:
npm run -s typecheck,lint,format:check,docs:check,mcp-catalog:check,verify:test-discovery,scan:todosandnpx knip: passed.npx vitest run --project domain --project services --project adapters: 17,246 passed, 25 skipped, 1 failed ("stops Inspector target authorization after the current stat settles"), which fails the same way on main in this environment.npm run test:prepare, thennpm run test:focused --the environment build, export and serve CLI boundaries, the analysis-view CLI and MCP boundaries, the environment serve, served-writes and bundle MCP boundaries, MCP schema validation and output schema constraints: 10 files, 82 passed.
Tests
- View: Go-spelled tag creates and renames are served with a trimmed clock; bookmark creates are served with a composed snapshot address and accept any URL; folder creates and renames are served with a composed address and a generated integer id.
- Serving: a served tag create spells its clocks without trailing zeros; a served bookmark create composes its snapshot address from the served clock and the sent URL; a served folder create gets a fresh sixteen-digit id and an address that follows its uid and title, and a rename moves the address.
- Unit: fitting clock formats (trimmed, fixed width, separator and zone), calendar digits, seeded integers, generated integer detection, composition and its refusals (one call alone, a held entity spelling otherwise, two sources with one text, a member stored otherwise than sent, a value the parts do not spell before the call), and a wide body composed within the existing time limit.
Write plans over recorded captures
Every write plan of 69 captures, built by the baseline and by this branch: the 50 published captures, 18 captures Claude Code recorded from a prompt for the prompt branch's checks, and one new timed Grafana recording.
| Captures | Write plans | Served on the baseline | Served on this branch |
|---|---|---|---|
| 50 published | 187 | 68 | 68 |
| 19 recorded from a prompt | 120 | 56 | 61 |
- No write goes from served to withheld. The five gains are Linkding's bookmark create, Homebox's tag create, and Grafana's folder create in two recordings and folder rename in the timed one.
- Published plans change only where a value is now composed: Linkding's bookmark create and BookStack's book create and
update (
description_htmlas<p>around the description) now accept the member they read. - Unchanged by design: Grafana's published folder, whose uid and title slug are the same text, so its address names two
sources; Ghost's post update, whose
lexicalkeeps thederivedrule that explained it before; BookStack's page HTML and Jellyfin's playlist path, which other pages and playlists of the capture spell otherwise. - What still withholds a create the composed value now explains: a later Linkding create that sends a member the first
did not (
shared), Homebox item creates that differ from the first location create, and a Linkding create whose read-back liststag_namessorted.
Served write tasks
The same timed captures, rebuilt by the baseline and by this branch, with the models fireworks_ai/gpt-oss-120b and
fireworks_ai/glm-5p3-flash. Create tasks are new; recorded write tasks are the applications' existing ones with entity
counts taken relative to each bundle's state.
| Application | Tasks | Baseline (gpt-oss, GLM) | This branch (gpt-oss, GLM) |
|---|---|---|---|
| Linkding | 2 bookmark creates | 0/2, 0/2 | 2/2, 2/2 |
| Linkding | 3 recorded (update, notes, delete) | 3/3, 3/3 | 3/3, 3/3 |
| Homebox | 2 tag creates | 0/2, 0/2 | 2/2, 2/2 |
| Homebox | 2 recorded deletes | 0/2, 0/2 | 0/2, 0/2 |
| Grafana | folder create and rename | not served | 1/2, 2/2 |
| Grafana | 2 recorded deletes | 2/2, 2/2 |
- Smoke and retrieval match on both builds (Linkding 9/9 and 8/9, Homebox 3/3 and 3/3); Grafana's new recording passes its smoke task and 9/9 retrieval with both models.
- gpt-oss missed the Grafana rename by sending the update without the title it was asked to change, ten times; the served environment refused each call with the members it accepts.
- Homebox's recorded deletes fail on both builds: this recording's served entity list holds its locations only, so the models never find the item to delete.
- The created bookmarks' snapshot addresses and the created and renamed folders' addresses are checked from the environment's state.
