+description: Load this when any modification to The-Interdependency/The-Interdependency.github.io is planned or underway, including source, content, configuration, tests, workflows, dependencies, generated-contract code, or deployment paths. Every website change transaction must append at least one By the builder entry recording date, time, and the exact runtime model; the model chooses the subject and writes no more than needed to explicate it. Do not load for read-only inspection that changes no website file.

+
+# website-builder-journal — every build leaves a builder trace
+
+Use this procedural skill before changing `The-Interdependency/The-Interdependency.github.io`.
+
+## Core contract
+
+A website modification is incomplete until the builder expands **By the builder**.
+
+For every change transaction that modifies any website-repository file other than the journal append itself:
+
+1. append at least one new record to `src/_data/builder.json`;
+2. preserve every previously published record byte-for-byte in value and order;
+3. record the entry's **date**, **time**, and **exact runtime model**;
+4. render the journal behind the site's collapsible `<details>` tree; and
+5. pass the repository's builder-history gate before merge.
+
+The journal append is part of the same transaction and does not recursively require a second append. Read-only inspection that changes no website file is the non-trigger.
+
+## Entry contract
+
+New records require:
+
+```json
+{
+  "id": "<stable-fragment>",
+  "date": "YYYY-MM-DD",
+  "time": "HH:MM±HH:MM",
+  "model": "<exact runtime model>",
+  "body": "<builder-chosen subject>"
+}
+```
+
+`id` is a stable technical anchor. Optional fields may support presentation or append-only correction links, but they must not create editorial requirements beyond this contract.
+
+### Exact model
+
+Write the full model identity actually executing the modification, not a provider, product, role, or generic agent label. Examples of insufficient values include `OpenAI`, `Codex`, `Claude`, `builder`, or `AI`.
+
+If the runtime does not expose enough information to identify its exact model, the website modification remains blocked at `hmmm`; do not invent a model name.
+
+### Subject and length
+
+The model has complete discretion over the journal entry's subject matter. It does not have to summarize the patch, justify the modification, discuss the website, or follow a recurring theme.
+
+Write only as much as is required to properly explicate the chosen subject. There is no minimum length, target length, mandatory title, changelog template, or required rhetorical shape.
+
+## Append-only boundary
+
+Previously published entries are immutable.
+
+- Corrections are new entries; never rewrite the earlier entry.
+- Deletion, replacement, or reordering of prior entries fails the gate.
+- Historical records that predate the date/time/model contract remain unchanged. Do not backfill them, because doing so would violate the stronger append-only rule.
+- New entries must satisfy the current entry contract.
+
+## Collapsible-tree boundary
+
+`/by-the-builder/` is a static-first collapsible tree implemented with semantic `<details>` / `<summary>` elements. JavaScript may enhance it but must not be required to read the entries.
+
+The tree presentation may evolve. The requirements that survive presentation changes are: the journal remains collapsible, every entry remains reachable, and its date, time, and exact model remain visible.
+
+## Workflow
+
+1. Resolve the exact website base commit before editing.
+2. Make the authorized website modification.
+3. Before terminal validation, append one or more compliant builder records.
+4. Run:
+   ```bash
+   npm run check:builder -- --base <base-commit>
+   ```
+5. Run the website's normal release gate.
+6. Merge only if the builder-history contract and the website's other required checks pass.
+
+The builder-history checker is enforcement; this skill is the behavior contract. Neither substitutes for the other.
+
+## Validation
+
+A conforming implementation proves all of the following:
+
+- a non-journal website diff with zero appended entries fails;
+- a non-journal website diff with at least one valid appended entry may proceed;
+- a journal-only append does not trigger infinite self-requirement;
+- prior entries cannot be edited, deleted, or reordered;
+- every newly appended entry has non-empty `date`, `time`, `model`, and `body`;
+- the time includes an explicit UTC offset;
+- generic provider/agent labels are not accepted as substitutes for the exact model by doctrine;
+- the public route renders the entries inside a collapsible semantic tree;
+- the gate runs in the website's normal validation path.
+
+## Anti-patterns
+
+- Treating the journal as an optional changelog.
+- Appending one entry once and letting later website changes reuse it.
+- Rewriting an old entry to add the newly required model or time.
+- Forcing the entry to describe the patch.
+- Padding an entry to satisfy an invented word count.
+- Recording only the provider or agent product instead of the exact model.
+- Requiring another append because the current transaction appended to the journal.
+
+## Usage guidance
+
+When this skill is installed in the website repository, load it before the first write. The smallest compliant transaction is:
+
+```text
+website change
++ one new builder record {date, time, exact model, body}
++ check:builder
++ normal website release gate
+```
+
+## hmmm
+
+The first published builder entry predates the date/time/exact-model contract. It remains intentionally unchanged because append-only history outranks retroactive schema neatness.

 ## Maintaining the builder journal
 
-Append a new object to `src/_data/builder.json` with a unique `id`, an ISO calendar `date`, `author`, `title`, and Markdown `body`. Preserve every prior record. A correction adds `correction_of` naming an earlier entry; it does not rewrite the earlier body. Entries render in stored chronological order with stable fragment links.
+The canonical behavior contract is `The-Interdependency/skill-lib:website-builder-journal`, consumed here from commit `0981aed7695ba2675d5de35ef43ba734e94adea0`. Before changing any website file, load `.agents/skills/website-builder-journal/SKILL.md`.
+
+Every website change transaction appends at least one object to `src/_data/builder.json`. Preserve every prior object unchanged. New entries require a unique `id`, `date`, `time` with explicit UTC offset, exact runtime `model`, and Markdown `body`. Subject matter belongs wholly to the model; no title, patch summary, theme, minimum length, or changelog structure is required. Corrections append new entries.
+
+The journal append is part of the transaction and does not recursively require another append. `/by-the-builder/` renders the journal as a nested semantic `<details>` tree.
 
 ```bash
 npm run check:builder -- --base <previous-commit>
 node --test tests/builder-history.test.mjs
 ```
 
-Normal PR checks compare against the PR base; push checks use the pre-push commit. Scheduled/local checks default to `HEAD^`. Missing Git history fails, so the PR and Pages build checkouts fetch full history. The guard protects the release workflow; it is not immutable storage against a repository administrator.
+The gate compares changed repository paths with the selected Git base. Any non-journal change with zero appended entries fails. PR checks compare against the PR base; push checks use the pre-push commit; scheduled/local checks default to `HEAD^`. Missing Git history fails closed.
 
-The [September 17 site audit](docs/site-audit-2026-09-17.md) records the changes, evidence, and remaining limits.
+The [September 17 site audit](docs/site-audit-2026-09-17.md) records the earlier journal boundary; the first published entry remains intentionally legacy because append-only history forbids retroactive time/model backfill.
