pipelines STOP for explicit user sign-off after the requirement is written +

scripts/migrate-v0.7-to-v0.8.sh.## Change Impact Analysis section to the coder sub-agent
(espalier/agents/harness-coder.md) and a ## Runtime-Surface Review section
to the reviewer sub-agent (espalier/agents/harness-reviewer.md). Both make
the agents reason about every surface a change touches (admin UIs, API
validation, client forms, persisted data, other callers) — not just the
programmatic happy path — so a now-derived value left user-required on a UI is
caught at coding/review instead of returning as a fix round. Mechanical:
scripts/migrate-v0.8-to-v0.8.1.sh.pipeline.md, espalier-fix), appends a ## Re-review Rounds
section to harness-reviewer.md, and inserts the certificate check into
pre-push-gate.sh. Mechanical: scripts/migrate-v0.8.1-to-v0.8.2.sh.harness-security agent joins Stage 4 as a review panel; a
security-standards rule + espalier-security skill are added, and the
coder/reviewer/testing/push-gate gain security sections. Ships
/espalier-audit, the repo-wide audit lane (espalier-audit skill + a
Repo-Audit Mode section). Adds an always-loaded production-standards rule
(resilience / observability / data-safety, tiered severity) the coder writes
to and the reviewer enforces; per-round VERDICT: sentinels + dual-record
freshness; a fail-closed push gate (cwd guard) + programmatic build/lint gate;
a deploy-aware Stage 9; the TTY→explicit-signal gate fix; and a single shipped
scout-prompts file for prune/doctor. Creates the new per-project files,
bootstrap --force refreshes the pure-copy pipeline/grill/hooks + copies
scout-prompts + symlinks both new rules + runs the 37-check validation, and
surgical appends patch the per-project files. Mechanical:
scripts/migrate-v0.8.2-to-v0.9.0.sh.espalier/.espalier-config (max-req-rounds, max-code-rounds,
max-test-rounds, max-rollbacks — all default 3) the orchestrator reads at
runtime. Creates the config file if absent (preserved on re-run) and refreshes
the three pure-copy pipeline files (pipeline.md,
espalier/skills/espalier/SKILL.md, espalier-fix) so their prose reads the
config; a customised file is backed up to <file>.pre-v0.9.1.bak. Mechanical:
scripts/migrate-v0.9.0-to-v0.9.1.sh.# Bug: title, and its
regression verification is scoped + dep-linked (no more false true from a
suite that couldn't run); /espalier-audit's fix handoff and
/espalier-prune's unattended path key off interactivity_mode; the push
gate gates the ACTIVE change (completed changes stop blocking later manual
pushes) and parses mocha/rspec/go test counts, preserving the substituted
test command; scout 1.11 ships in .scout-prompts.md and prune/doctor map
the security/production rules. Backs up customised pure-copy files to
<file>.pre-v0.9.2.bak. Mechanical: scripts/migrate-v0.9.1-to-v0.9.2.sh.espalier-grill (pure-copy) gains an
explicit user tier-override, a coverage guard so every counted ambiguity signal
ends resolved / scoped-out / recorded in ## Open Questions, and records a
non-answer with a named safe default instead of dropping it. espalier-review
(substituted) gets its two review loops rewritten as an explicit
when / input / do / output / who workflow, stops restating severities in the
production-readiness checklist (production-standards.md is the single source),
and gains when-to-use + trigger phrases in its frontmatter. Backs both skills up
to <file>.pre-v0.9.3.bak. Mechanical: scripts/migrate-v0.9.2-to-v0.9.3.sh.harness-security AGENT

"findings do not block" delta stop restating each other's semantics,
cross-referencing one source instead. Both are per-project files that

# Espalier Migration Runner
## When to Use
- "Migrate to Espalier" / "Upgrade my Espalier install"
- "Upgrade my harness to the latest version"
- "Rename harness/ to espalier/"
- "/espalier-migrate"
## When NOT to Use
- Fresh project with no existing `harness/` or `espalier/` dir → use `/espalier-init` instead.
- Already fully up to date — `/espalier-migrate` detects this itself and exits cleanly with no changes.
## Instructions
You are running a migration of an existing install to the current Espalier
version. Up to THIRTY-FOUR migrations may apply, always in this order:
1. **v0.1.x → v0.2.x** — typed `harness/changes/{type}/{slug}/` layout,
`/harness-fix` lane, squash-merge decision. Mechanical:
`scripts/migrate-v0.1-to-v0.2.sh`.
2. **v0.3.x → v0.4.0** — `harness/` → `espalier/` directory + skill rename
(`harness-run` → `espalier`, `harness-{coding,…}` → `espalier-*`).
Mechanical: `scripts/migrate-v0.3-to-v0.4.sh`.
3. **v0.4.x → v0.5.0** — doc-drift detection: drift hooks, the
`/espalier-prune` + `/espalier-doctor` skills, the post-merge dispatcher,
`.doctor-cadence`. Mechanical: `scripts/migrate-v0.4-to-v0.5.sh`.
4. **v0.5.0–v0.5.2 → v0.5.3** — appends the `## Editing Discipline` section to
the coder sub-agent (`espalier/agents/harness-coder.md`). Mechanical:
`scripts/migrate-v0.5.2-to-v0.5.3.sh`.
5. **v0.5.x → v0.6.0** — Stage 1 grilling: installs the `espalier-grill` skill,
refreshes the four changed pipeline templates (which also date-prefix change
folders). Mechanical: `scripts/migrate-v0.5-to-v0.6.sh`.
6. **v0.6.x → v0.7.0** — read-only ask lane: installs the `espalier-ask` skill,
patches CLAUDE.md + `espalier/agent.md` to mention `/espalier-ask`. Purely
additive — no pipeline change. Mechanical: `scripts/migrate-v0.6-to-v0.7.sh`.
7. **v0.7.x → v0.8.0** — requirements approval gate: refreshes the three changed
pipeline templates (`pipeline.md`, `espalier`, `espalier-fix`) so both
pipelines STOP for explicit user sign-off after the requirement is written +
reviewed, before any code is written (no-TTY runs auto-approve). Mechanical:
`scripts/migrate-v0.7-to-v0.8.sh`.
8. **v0.8.0 → v0.8.1** — impact-analysis agent patch: appends a
`## Change Impact Analysis` section to the coder sub-agent
(`espalier/agents/harness-coder.md`) and a `## Runtime-Surface Review` section
to the reviewer sub-agent (`espalier/agents/harness-reviewer.md`). Both make
the agents reason about every surface a change touches (admin UIs, API
validation, client forms, persisted data, other callers) — not just the
programmatic happy path — so a now-derived value left user-required on a UI is
caught at coding/review instead of returning as a fix round. Mechanical:
`scripts/migrate-v0.8-to-v0.8.1.sh`.
9. **v0.8.1 → v0.8.2** — re-review fixpoint loop + push-gate certificate: code
review becomes a loop — every coder fix is re-reviewed until a fresh review of
the current code returns zero P0 — and the push gate blocks unless the pushed
code matches the fingerprint the last review saw. Refreshes the two pure-copy
pipeline files (`pipeline.md`, `espalier-fix`), appends a `## Re-review Rounds`
section to `harness-reviewer.md`, and inserts the certificate check into
`pre-push-gate.sh`. Mechanical: `scripts/migrate-v0.8.1-to-v0.8.2.sh`.
10. **v0.8.2 → v0.9.0** — security audit + production hardening (one release):
a new `harness-security` agent joins Stage 4 as a review panel; a
`security-standards` rule + `espalier-security` skill are added, and the
coder/reviewer/testing/push-gate gain security sections. Ships
`/espalier-audit`, the repo-wide audit lane (`espalier-audit` skill + a
Repo-Audit Mode section). Adds an always-loaded `production-standards` rule
(resilience / observability / data-safety, tiered severity) the coder writes
to and the reviewer enforces; per-round `VERDICT:` sentinels + dual-record
freshness; a fail-closed push gate (cwd guard) + programmatic build/lint gate;
a deploy-aware Stage 9; the TTY→explicit-signal gate fix; and a single shipped
`scout-prompts` file for prune/doctor. Creates the new per-project files,
`bootstrap --force` refreshes the pure-copy pipeline/grill/hooks + copies
scout-prompts + symlinks both new rules + runs the 37-check validation, and
surgical appends patch the per-project files. Mechanical:
`scripts/migrate-v0.8.2-to-v0.9.0.sh`.
11. **v0.9.0 → v0.9.1** — configurable escalation caps: the review-round +
rollback hard stops move from hardcoded prose into a tracked
`espalier/.espalier-config` (`max-req-rounds`, `max-code-rounds`,
`max-test-rounds`, `max-rollbacks` — all default 3) the orchestrator reads at
runtime. Creates the config file if absent (preserved on re-run) and refreshes
the three pure-copy pipeline files (`pipeline.md`,
`espalier/skills/espalier/SKILL.md`, `espalier-fix`) so their prose reads the
config; a customised file is backed up to `<file>.pre-v0.9.1.bak`. Mechanical:
`scripts/migrate-v0.9.0-to-v0.9.1.sh`.
12. **v0.9.1 → v0.9.2** — correctness patch: the fix lane's late-escalation
gates detect via a marker line (the old text called a shell helper that was
never shipped), its back-link reads the real `# Bug:` title, and its
regression verification is scoped + dep-linked (no more false `true` from a
suite that couldn't run); `/espalier-audit`'s fix handoff and
`/espalier-prune`'s unattended path key off `interactivity_mode`; the push
gate gates the ACTIVE change (completed changes stop blocking later manual
pushes) and parses mocha/rspec/go test counts, preserving the substituted
test command; scout 1.11 ships in `.scout-prompts.md` and prune/doctor map
the security/production rules. Backs up customised pure-copy files to
`<file>.pre-v0.9.2.bak`. Mechanical: `scripts/migrate-v0.9.1-to-v0.9.2.sh`.
13. **v0.9.2 → v0.9.3** — skill-clarity patch; no new lane, no new stage, no
behaviour change to any gate or verdict. `espalier-grill` (pure-copy) gains an
explicit user tier-override, a coverage guard so every counted ambiguity signal
ends resolved / scoped-out / recorded in `## Open Questions`, and records a
non-answer with a named safe default instead of dropping it. `espalier-review`
(substituted) gets its two review loops rewritten as an explicit
when / input / do / output / who workflow, stops restating severities in the
production-readiness checklist (`production-standards.md` is the single source),
and gains when-to-use + trigger phrases in its frontmatter. Backs both skills up
to `<file>.pre-v0.9.3.bak`. Mechanical: `scripts/migrate-v0.9.2-to-v0.9.3.sh`.
14. **v0.9.3 → v0.9.4** — security-skill patch; no new lane, no new stage, no
behaviour change to any gate or verdict (the security auditor's catch /
false-positive rates are unchanged). The per-project `harness-security` AGENT
and `espalier-security` SKILL gain when-to-use + the five sensitive axes as
frontmatter trigger context, and the agent's P0 rubric and repo-audit
"findings do not block" delta stop restating each other's semantics,
cross-referencing one source instead. Both are per-project files that
`bootstrap --force` never re-copies, so v0.9.4 shipped these template
improvements with no way to reach an existing install. Frontmatter is edited
