Summary

Compresses the two pending_review_gate nodes in github-pr.yaml and ado-pr.yaml from blocking human_gate nodes into an emit + script-poll pattern, following the gate-compression-pattern ADR (docs/decisions/gate-compression-pattern.md).

Gates compressed: 2
Both pending_review_gate nodes were category-1 (deterministic-outcome): the workflow was pausing to wait for a human to take an action on the PR (merge, approve, comment, close) that Poll-PrStateDelta.ps1 can detect directly. They stay compressed.

Gates staying as human gates: 17
poll_error_gate, revise_cap_gate, remediation_cap_gate, stuck_review_gate, pr_pre_merge_gate, merge_failed_gate and others — all genuine judgment calls, config errors, or infrastructure failures. They are unchanged.

Per-file changes

github-pr.yaml (v2.4.8 → v2.5.0)

  • Added poll_timeout_seconds (default 86400 s / 24 h) and poll_interval_seconds (default 30 s) as optional workflow inputs
  • Added notifications: block (polyphony.github_pr namespace) with types pr_review_required and pr_ci_attention_required
  • Replaced three nodes (pending_poll_counter + pending_review_gate_policy_router + pending_review_gate) with:
    • notify_pr_pending — emits pr_review_required domain signal once when gate opens
    • poll_pr_state_delta — calls Poll-PrStateDelta.ps1; blocks until reaction or timeout
    • notify_pr_ci_attention — emits pr_ci_attention_required on CI FAILURE (Q3 Option C)
  • Added notify_pr_review_resolved before already_merged_emitter (emits disposition:resolved to close the pending CTA)
  • Updated stuck_review_gate prompt (removed pending_poll_counter template refs; timeout-based description)
  • Rewired stuck_review_reset → poll_pr_state_delta
  • Rewired pr_pre_merge_gate.defer → poll_pr_state_delta

ado-pr.yaml (v2.4.8 → v2.5.0)

Same pattern as GitHub with ADO-specific details:

  • poll_pr_state_delta uses -Platform ado; coords parsed from PrUrl by the script
  • notify_pr_pending payload includes organization and project
  • CI attention threshold uses 'failed' (ADO build policy status string)
  • ADO vote mapping documented in node comments (+5/+10 → approved, -10/-5 → changes_requested)

Script: Poll-PrStateDelta.ps1

Added Liszt's implementation (was untracked). One small contract gap patched:

WatermarkPath was mandatory in Liszt's implementation but optional in Wagner's plan §3.2. Made optional: when omitted, the path is auto-derived from PR coordinates (platform-owner-repo-number). This allows the YAML to omit -WatermarkPath entirely.

Reaction-kind contract note

Liszt's actual reaction_kind enum differs slightly from Wagner's plan. The YAML routing uses Liszt's actual values:

Liszt's value Meaning
initial_observation First call, watermark just established — YAML routes back to re-poll
pr_merged / pr_closed Terminal PR states
new_review_approved / new_review_changes_requested / new_review_commented Review reactions
new_commit / new_comment Commit/comment activity
ci_status_changed CI status flip (with delta_details.new for green/red routing)
timeout Budget elapsed — escalates to stuck_review_gate_policy_router

on_error: → poll_error_gate is deferred to AB#3257 (conductor RFC Phase 2 — on_error: in routes not yet shipped in v0.1.18).

Pester tests for the script (Poll-PrStateDelta.Tests.ps1) are included and were AST-clean per Liszt. Full test execution is follow-up work.

ADRs added

  • docs/decisions/gate-compression-pattern.md — the pattern this PR implements (Bach)
  • docs/decisions/domain-signal-envelope.md — dependency (Bach)
  • docs/decisions/polyphony-verb-error-boundary.md — dependency (Bach)
  • docs/north-star.md — high-level vision doc (Bach)

Open follow-ups

  • AB#3257: Add on_error: to: poll_error_gate to poll_pr_state_delta once conductor RFC Phase 2 ships
  • Post upstream PR Closed-loop step 2: wire PlanObserver into state next-ready #213 cherry-pick (27006af): bulk-rename type: notification → type: emit and notification: → emit: in both files
  • Run Poll-PrStateDelta.Tests.ps1 in CI
  • Thread poll_timeout_seconds / poll_interval_seconds through feature-pr.yaml and implement-merge-group.yaml callers

refactor(workflows): compress pending_review_gate to emit + script-po…
d5b37d8 
…ll pattern

Implements the gate-compression-pattern ADR (docs/decisions/gate-compression-pattern.md)
for the two pending_review_gate nodes across github-pr.yaml and ado-pr.yaml.

## Gates compressed (2)
- github-pr.yaml: pending_review_gate (line 1025 on main)
- ado-pr.yaml:    pending_review_gate (line 1146 on main)

Both gates were category-1 (deterministic-outcome): the workflow was pausing to
wait for a human to take an action on the PR (merge, approve, comment, or close)
that Poll-PrStateDelta.ps1 can detect directly.

## Vestigial cleanup (Q5 Option A)
- Removed pending_poll_counter per-file (counter logic superseded by TimeoutSeconds)
- Removed pending_review_gate_policy_router per-file (skip/wait/auto modes superseded)
- Rewired stuck_review_reset -> poll_pr_state_delta (router gone)
- Rewired pr_pre_merge_gate.defer -> poll_pr_state_delta (gate gone)
- Updated stuck_review_gate prompts to remove pending_poll_counter template refs

## Per-file changes

### github-pr.yaml
- Added poll_timeout_seconds / poll_interval_seconds optional inputs (default 86400 / 30)
- Added notifications: block (polyphony.github_pr namespace)
- Added types: pr_review_required, pr_ci_attention_required
- pr_feedback_analyzer catch-all: pending_poll_counter -> notify_pr_pending
- New nodes: notify_pr_pending, poll_pr_state_delta, notify_pr_ci_attention
- New node: notify_pr_review_resolved (inserted before already_merged_emitter)
- Version bump: 2.4.8 -> 2.5.0

### ado-pr.yaml
- Same structure as github-pr.yaml with ADO-specific args and payload fields
- poll_pr_state_delta uses -Platform ado (coords parsed from PrUrl by script)
- ci_status_changed FAILURE threshold uses 'failed' (ADO build policy status)
- Version bump: 2.4.8 -> 2.5.0

## Script: Poll-PrStateDelta.ps1
- Added Liszt's implementation (scripts/Poll-PrStateDelta.ps1 + Tests)
- Contract gap patched: WatermarkPath is now optional; auto-derived from
  PR coords (platform+owner+repo+number) when not supplied by caller.
  This aligns with Wagner's plan §3.2 and allows the YAML to omit -WatermarkPath.
- Tests (Poll-PrStateDelta.Tests.ps1) included as-is; AST-clean per Liszt.
  Full test execution is follow-up work.

## Script contract gaps noted (for follow-up)
- reaction_kind enum in script differs from Wagner's plan:
  pr_merged/pr_closed (not merged/closed), ci_status_changed (not ci_changed),
  new_review_approved/changes_requested/commented (not new_review).
  YAML routing uses Liszt's actual values throughout.
- initial_observation is a new kind (first call, no watermark); YAML routes
  it back to poll_pr_state_delta to re-poll immediately.
- on_error: -> poll_error_gate deferred to AB#3257 (conductor RFC Phase 2).

## ADRs added
- docs/decisions/gate-compression-pattern.md (Bach)
- docs/decisions/domain-signal-envelope.md (Bach, dependency of above)
- docs/decisions/polyphony-verb-error-boundary.md (Bach, dependency of above)
- docs/north-star.md (Bach)

fix(scripts): Poll-PrStateDelta strict-mode crash + over-greedy test …
b37d85f 
…stub

Five pre-existing bugs surfaced when running Pester locally:

1. Script: Invoke-AssertCli referenced `.Exe`, a property that
   doesn't exist on the returned object. Under Set-StrictMode -Version
   Latest this throws PropertyNotFoundException before the auth / 404 /
   rate-limit catch chain runs, collapsing 401/404/429 all to exit
   code 5. Fixed by removing the redundant `-not `.Exe -and`
   guard (ExitCode -eq -1 plus the 'not found on PATH' regex already
   identify this case unambiguously).

2. Test: Build-GhStub's PR-core pattern 'api repos/*/pulls/* --jq *'
   also matched '/pulls/{n}/reviews' because '*' greedily eats the URL
   tail. Tightened to '--jq {*' so the brace discriminates against
   the reviews/comments/CI paths (whose jq filters start with '[').

3. Script: Find-GitHubDeltas / Find-AdoDeltas return a typed
   List[hashtable] via the PowerShell pipeline. An empty list yields
   ``; a single-item list yields that one hashtable — neither has
   a reliable .Count. Wrapped the call-site assignment in `@()` so
   `` is always a plain array.

4. Script: Select-HighestPrecedenceDelta declared its parameter as
   [System.Collections.Generic.List[hashtable]]. Under StrictMode,
   passing a plain hashtable (single-delta case) triggered a
   PropertyNotFoundException during argument binding. Removed the
   type constraint — the function body only iterates and accesses
   hashtable keys, so no type hint is needed.

5. Test: ConvertFrom-Json auto-promotes ISO-8601 date strings to
   System.DateTime objects; the Should -Match regex then ran against
   DateTime.ToString() which does not produce 'Zulu' notation.
   Fixed by normalising to string with the expected format before
   asserting in 'Always emits observed_at_utc in ISO 8601 format'.
   Also bumped TimeoutSeconds to 30 for the 'pr_merged + new_commit'
   precedence test whose CI-stub subprocess calls made one full poll
   exceed the prior 10-second ceiling under load.

Pester now 30/30 green (1 slow-test skip intentional) on the
refactor/pr-gate-compression-v2 branch.

📊 Pester verification — 5 pre-existing bugs caught + patched

Ran scripts/Poll-PrStateDelta.Tests.ps1 locally on this branch and found 5 bugs that pre-date this PR:

  1. Script — Invoke-AssertCli accessed nonexistent \$Result.Exe under StrictMode → PropertyNotFoundException collapsed 401/404/429 to exit code 5. Fixed by removing the redundant guard (ExitCode -eq -1 + 'not found on PATH' regex already suffices).

  2. Test — Build-GhStub PR-core glob 'api repos/*/pulls/* --jq *' also matched /pulls/{n}/reviews because * is greedy. Tightened to --jq {* (jq filter for the PR-core call starts with {).

  3. Script — Find-GitHubDeltas returns a typed List[hashtable] through the pipeline: empty list → \, single item → bare hashtable. \.Count was unreliable in both cases. Wrapped call-site in @() to always produce a plain array.

  4. Script — Select-HighestPrecedenceDelta declared [System.Collections.Generic.List[hashtable]]\. StrictMode threw PropertyNotFoundException when a plain hashtable (single-delta) was passed. Removed the type constraint.

  5. Test — ConvertFrom-Json auto-promotes ISO-8601 strings to DateTime objects; Should -Match was receiving a DateTime's ToString() output. Fixed by normalising to string before asserting. Also bumped one test's TimeoutSeconds from 10→30 so CI-stub subprocess latency doesn't cause a spurious timeout.

Fixed in commit b37d85f. Pester is now 30/30 green (1 intentional skip for the 60s+ hang test).

— Liszt
