2. Apply every triggered coding-standard and simplification rule to the
effective task delta. Treat scripts, searches, formatters, compilation, tests,
benchmarks, and review tools as evidence rather than proof, and fix every safe
in-scope violation.
3. Run the applicable verification and non-regression checks. An invalidated,
unmatched, missing, or inconclusive required result keeps the task incomplete.
4. Use bounded self-review for an internal local candidate when inspection
proves that its frozen owners and behavior are fully understood, module
dependencies and public or externally visible contracts are unchanged,
applicable verification is complete, and no Formal Review trigger below is
present. The candidate may span files or modules when they implement one
bounded behavior and verification covers every changed owner and affected
consumer. Review root-cause and fix mapping, affecte [...]

6. Fix every safe in-scope required finding, repeat the task-delta audit,
rerun invalidated checks, and repeat the applicable review. Stop at the
existing gate for a scope expansion, unresolved architecture choice, high-risk
action, `Review Incomplete`, or `Needs Discussion` result.
7. Hand off a bounded-review candidate only after the review finds no required
issue. Include its concise completed review result in the final handoff. Hand
off a Formal Review candidate only after the latest complete report returns
`Review Result: Mergeable`, and include the complete Formal Review report in
the final handoff.
8. After a code-writing task completes, provide a commit message without being
asked; this never authorizes Git mutation. Provide manual Git commands only
when the user requests them. Propose `git commit --dry-run --only` and `git
commit --only` for only task-owned files without unrelated hunks, list a
required `git add -- <new-task-paths>` first for untracked task files, and
never execute a Git write without exact current-task authorization.
+When the delta audit, required current-state checks, and applicable review
pass and no later write or new evidence invalidates them, the loop is complete.
Do not repeat an unchanged check, audit, or review.
+
If a report or verdict is disproved, fix the highest-leverage rule, schema,
validator, prompt, or regression case before correcting the artifact, unless
the user explicitly requests a one-off correction.
The final response must lead with the outcome and include changed files and
rationale, verification status, remaining risks, and the next action only when
one is still required. Every code-writing handoff must explicitly report the
completed code review result and review recommendations. State the blocking
issue count and required changes, and explicitly state `No changes recommended`
when no findings exist. Do not omit the review output merely because the review
was performed internally [...]

exact additional path and change intent.

### Remote Writes and Sensitive Data
-- A local request does not authorize a remote update; write only when the
current request names the exact remote action and target.
+- A local request does not authorize a remote update; require the exact remote

- For GitHub, use `GH_TOKEN`, then `GITHUB_TOKEN`, without exposing either;

For Docker cleanup, distinguish reproducible images from containers, volumes,

confirmation; the other categories remain unauthorized unless named.

cost. Separate evidence from inference and preference; when evidence

alternative before acting.

registrations, boundaries, precedent, and instructions; then record a compact

### Strict Scope and Task-Delta Gate
-1. An active task is one independent, verifiable objective including its
corrections and follow-ups. Start a new baseline only after completion and an
explicit independent objective; when ambiguous, stay read-only and confirm.
Findings, failures, reviews, and module mentions do not start a task.
-2. Derive acceptance criteria only from requested outcomes, proven direct
prerequisites, and focused regression protection. Do not promote cleanup,
refactoring, generalization, consistency, adjacent fixes, or optional
improvements; a prerequisite qualifies only when no smaller in-boundary option
can preserve behavior, compilation, or verification.

prerequisites, and focused regression protection. Do not add cleanup,
generalization, consistency work, adjacent fixes, or optional improvements.
3. Before a file-changing tool, record original status and relevant diffs,
infer the smallest owning paths, and freeze `file -> allowed intent -> unmet
criterion`. A named module or path is the maximum boundary, and an allowed file
does not authorize unrelated hunks.
4. Keep the baseline and boundary through follow-ups, reviews, failures, and
verification. Expand only with exact additional path and intent authorization,
append without rebaselining, and keep other scope read-only.
-5. Map every task hunk and inspect all paths and hunks after each coherent
precise edit. Inspect immediately after a formatter, generator, bulk
replacement, or other action whose write set is not exact. Before an
outside-boundary edit, report its evidence, minimum scope, affected contracts,

6. Preserve pre-existing and unattributed changes; do not overwrite, format,
remove, roll back, or claim them, and do not infer ownership from baseline
absence.

only safely separable unnecessary task changes, and hand off `file -> behavior
-> criterion -> necessity`.

-Architecture changes include public contracts, SPIs, extension or loading
contracts, module dependencies, shared ownership, and changes to `final`,
visibility, inheritance, constructors, or signatures at a public or shared
module boundary. A private internal signature or constructor change is not
architectural by itself; still verify its owner, callers, compatibility, and
minimum files and tests under the ordinary scope rules. Before an architecture
edit, report ownership, reuse or deleg [...]
+Architecture changes include public contracts, SPIs, extension or loading

different choices and always gate an SPI change.
If the user rejects a design, stop patching it. Remove only its proven task
changes, preserve unrelated work, and redesign from the last confirmed
boundary. Use precise edits unless the task authorizes an exact Git restore.
## Task Code Size Limit
-Do not add over 10,000 physical production and test source lines in one active
task without explicit authorization. Estimate before writing against the
original baseline across tools, scripts, Skills, modules, and later turns;
recount after a generator or bulk write, when the estimate reaches 8,000 lines,
and exactly after the last write. If projected or measured output exceeds the
limit, stop, report totals and paths, and propose the smallest independently
verifiable decomposition.

audit, checks, and review pass.
+Every authorized change, build, implementation, or fix follows
`.codex/context/change-completion.md`, except a governed standalone restoration
or rollback.
## Functional and Performance Non-Regression Gate
-Apply `.codex/skills/code-implementation/references/rules/non-regression.md`
when a change can affect supported product, build, or runtime behavior or has
credible performance cost. Freeze required baselines before editing, reject
unauthorized loss, and treat missing or inconclusive required evidence as
blocking. Do not benchmark when inspection rules out credible cost growth.
