Phase 8 / Task E2: Squash onto clean-pr + push + PR #136 refresh + @jahow tag

[Sam-Bolling]

Phase 8 Task

Task ID: E2
Title: Squash onto clean-pr + Push + PR #136 Refresh + @jahow Tag
Source: Phase 8 delivery sequence — final upstream handoff
Severity: N/A (delivery only — no source change)
Category: Delivery / Upstream PR / Maintainer Handoff
Ownership: Ours (clean-pr branch on OS4CSAPI/ogc-client; PR #136 on camptocamp/ogc-client)
Phase 8 phase: E — Verification & Delivery

---

Goal

Apply the phase-8.patch artifact (produced by Task E1) onto clean-pr as one squashed commit, push to refresh PR #136, verify CI green on the PR, update the PR description with a comprehensive Phase 8 section, and tag @jahow for final review with an explicit time-frame ask. After E2:

• PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 (camptocamp/ogc-client) carries one new squashed commit titled "Phase 8: API design refinements + CS-Go server-interop fixes"
• CI on PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 is green (GitHub Actions, all upstream-defined gates)
• PR description has a "## Phase 8" section listing acceptance-criteria recap (A1–A8 + B1–B2), resolved findings (017, 018, 019, 021, 022, 023, 024, Phase 8 / Task C1: Issue #166 — Part 2 @link fallback in cross-reference fields #166, Phase 8 / Task A4: Issue #167 — Pagination-contract JSDoc on list methods #167), wontfix list (Closed (wontfix): library is spec-correct; server-side root cause tracked at connected-systems-go#11; institutional knowledge preserved in references.md #168, Closed (wontfix): heuristic coordinate extraction not adopted; architecturally correct path tracked at #171 #169), and deferred list (020, 025, 026, Future-enhancement (deferred): async-iterator helpers for paginated CSAPI list methods — out-of-scope until upstream broadens scope #170, Deferred enhancement: SWE Common–aware result-vector extraction (out-of-scope until upstream broadens scope) #171)
• @jahow is tagged for final review with a time-frame ask
• Phase 8 is closed; PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 is in maintainer's hands

Acceptance criterion: Phase 8 is complete and PR #136 is ready for @jahow's final review.

Locked Decision

⚠️ This decision is locked. Do not re-litigate in this issue. Surface deviations to the user; do not silently re-decide.

Decision: Delivery is two-repo, single-squash:

• The planning repo (OS4CSAPI/ogc-client-CSAPI_2) keeps full per-task granular history on phase-8
• The delivery repo (OS4CSAPI/ogc-client) carries clean-pr with one new squashed commit (the only commit Phase 8 contributes upstream)
• The squashed commit message uses the canonical template from P8-implementation-guide.md §11

The mechanical-apply path is: git apply phase-8.patch (NOT git cherry-pick, NOT git merge, NOT git rebase). Patch-apply preserves the source-only scope fence E1 established and gives a clean single-commit result with no merge-history pollution.

If git apply fails (whitespace conflict, contextual drift), the recovery path is: return to phase-8 on the planning repo, regenerate the patch fresh from the current phase-7..phase-8 diff, and re-apply. Do not edit clean-pr source files manually to make a poisoned patch apply.

The PR description update is mandatory, not optional. The Phase 8 section gives @jahow a single-pane summary so the review burden is bounded.

The @jahow tag is the explicit handoff signal — without it, the maintainer has no notification that Phase 8 is review-ready.

Locked in:

• P8-implementation-guide.md §11 steps 4–8 — full delivery sequence + squashed commit message template
• P8-ROADMAP.md §Phase E Task E2 — task definition + acceptance gate
• P8-contribution-goal-and-definition.md — defines the resolved/wontfix/deferred finding sets that populate the PR description

---

Problem Statement

Phase 8's planning branch contains 8+ granular commits (A1–D1) plus the full docs/, app/, planning-MD churn. Upstream camptocamp/ogc-client cannot accept that history — PR #136 needs one clean squashed commit covering only src/ and fixtures/ changes. The two-repo workflow established in Phase 7 (P8-implementation-guide §11) handles this: OS4CSAPI/ogc-client is the upstream-shaped delivery branch (clean-pr), and phase-8.patch is the bridge.

Additionally, PR #136's existing description covers Phases 6 and 7 only. Without a Phase 8 section, @jahow has no scoped summary of what changed, what's in scope, what's deliberately deferred, and what's been closed wontfix. The maintainer would have to reverse-engineer all of that from the diff, which is precisely the friction the Phase 8 contribution-goal document was designed to eliminate.

Affected branches/repos:

• Source: OS4CSAPI/ogc-client-CSAPI_2 phase-8 HEAD + phase-8.patch artifact (produced by E1)
• Target: OS4CSAPI/ogc-client clean-pr branch
• PR: camptocamp/ogc-client#136 (refreshed by push to OS4CSAPI/ogc-client:clean-pr)

Files to Modify

File / Resource	Action	Est. Lines	Purpose
OS4CSAPI/ogc-client working tree (on clean-pr)	Apply patch	~950 LOC	Mechanical git apply phase-8.patch — no manual source edits
OS4CSAPI/ogc-client clean-pr branch	Push	(commit)	One new squashed commit pushed to refresh PR #136
PR #136 description (camptocamp/ogc-client)	Update	~80 lines	New "## Phase 8" section: acceptance-criteria recap (A1–A8 + B1–B2), resolved-findings list, wontfix list, deferred list
PR #136 review request	Tag	(comment)	@jahow tagged with explicit time-frame ask

Cross-reference P8-implementation-guide §11 steps 4–8 for the canonical command sequence and squashed-commit-message template. If you find yourself editing OS4CSAPI/ogc-client source files manually, stop — that's a regression, not E2's job.

Implementation Approach

Execute the canonical 9-step sequence verbatim from P8-implementation-guide §11 steps 4–8. Repository handoff is from OS4CSAPI/ogc-client-CSAPI_2 to OS4CSAPI/ogc-client; PR target is camptocamp/ogc-client#136.

Step 1 — Switch to the delivery repo (clone if needed):

# If not already cloned locally:
# git clone https://github.com/OS4CSAPI/ogc-client.git c:\Users\sbolling\Documents\ogc-client
cd c:\Users\sbolling\Documents\ogc-client
git fetch origin
git status              # working tree must be clean

Step 2 — Checkout clean-pr and ensure it is up-to-date:

git checkout clean-pr
git pull origin clean-pr
git log -1 --oneline    # confirm Phase 7's last squashed commit is HEAD

Step 3 — Apply the patch from E1:

# Adjust path as needed; phase-8.patch was produced by Task E1 in the planning repo
git apply c:\Users\sbolling\Documents\ogc-client-CSAPI_2\phase-8.patch

If git apply reports any error: do NOT manually edit files to force-fit the patch. Return to E1, regenerate the patch from current phase-7..phase-8 diff, retry. If the patch still fails, surface the question — there is a stale-baseline or context-drift problem to root-cause.

Step 4 — Stage all and inspect:

git add -A
git status              # expected: only src/ogc-api/csapi/**, src/ogc-api/endpoint.ts, src/ogc-api/index.ts, fixtures/csapi/** changes
git diff --cached --shortstat   # sanity-check LOC ~950

Step 5 — Commit with the canonical squashed commit message (template from P8-implementation-guide §11):

Phase 8: API design refinements + CS-Go server-interop fixes

Closes (resolved upstream-review findings 017–024 + repo issues #166, #167):

- 017: URL-builder framing in module-level docs (A1)
- 022: CSAPICollectionRef constructor type decoupling (A2)
- 023: availableResources tightened to ReadonlySet<CSAPIResourceType> (A3)
- #167: Pagination-contract JSDoc on list methods (A4)
- 019: DataStream → Datastream method rename (B1, 13 methods)
- 021: Validators throw EndpointError (B2)
- #166: Part 2 @link fallback in cross-reference fields (C1)
- 018 + 024: endpoint.csapi() convenience method + re-privatization (D1, coordinated)

Deliberately wontfix (out of Phase 8 scope per P8-contribution-goal §6):

- #168: getCollections / cross-collection helpers
- #169: getObservationsByDatastream / consumer-side ergonomics

Deferred to a future phase (per P8-contribution-goal §7):

- 020: SWE Common parser hardening
- 025: result-extraction error path
- 026: ad-hoc paging helpers
- #170: auto-pagination across pages
- #171: SWE Common-aware result extraction

CI: all five upstream gates green (format:check, typecheck, lint, test:browser, test:node).

Step 6 — Push to refresh PR #136:

git push origin clean-pr
# This refreshes the PR at camptocamp/ogc-client#136 (clean-pr is the head branch)

Step 7 — Verify CI on PR #136: open camptocamp#136, wait for GitHub Actions to complete, confirm all upstream-defined gates exit green. If any gate fails on the PR but was green locally in E1, root-cause the divergence (CI environment, Node version, OS) before tagging @jahow.

Step 8 — Update PR #136 description: add a "## Phase 8" section at the bottom (or replace if a Phase 8 stub exists). Use this structure:

## Phase 8

**Acceptance criteria met (8 + 2 = 10):**

- A1: URL-builder framing documented (Finding 017)
- A2: CSAPICollectionRef decoupling (Finding 022)
- A3: ReadonlySet<CSAPIResourceType> tightening (Finding 023)
- A4: Pagination JSDoc (#167)
- A5: No `@deprecated` introductions (locked-decision invariant)
- A6: `endpoint.root` / `getCollectionDocument` private (Finding 024)
- A7: `endpoint.csapi(id)` discoverable entry point (Finding 018)
- A8: No `isCollectionInfo` runtime cast (eliminated by D1)
- B1: `DataStream` → `Datastream` rename, 13 methods (Finding 019)
- B2: Validators throw `EndpointError`; factory wrapping closed in D1 (Finding 021)

**Resolved findings:** 017, 018, 019, 021, 022, 023, 024, #166, #167.
**Wontfix (out of scope):** #168, #169.
**Deferred to a future phase:** 020, 025, 026, #170, #171.

Net: ~400 source LOC + ~550 test LOC. No `app/`, `docs/`, or `src-node/` changes flow upstream.

Step 9 — Tag @jahow for final review with explicit time-frame ask. Use a PR comment (not just an "@" in the description), so it generates a notification:

@jahow — Phase 8 is ready for your final review. Could you take a look in the next ~2 weeks if your schedule allows? All five CI gates are green, the PR description's Phase 8 section summarizes scope. Happy to address any feedback either as fixup commits on clean-pr or as a Phase 9 follow-up, your call.

(Adjust the time-frame to whatever the user has agreed with @jahow.)

Scope — What NOT to Touch

• ❌ Do NOT modify any source file inside this task. E2 is mechanical apply + commit + push + description + tag. No manual source edits.
• ❌ Do NOT use git cherry-pick, git merge, or git rebase to bridge phase-8 → clean-pr. The locked path is git apply phase-8.patch.
• ❌ Do NOT amend or rewrite Phase 7's existing squashed commit on clean-pr. Phase 8 adds one new commit on top.
• ❌ Do NOT amend the Phase 8 squashed commit after the push without first informing the user. Force-pushes to clean-pr invalidate any review @jahow has started.
• ❌ Do NOT push to phase-8 from this task. E2 operates only on the OS4CSAPI/ogc-client repo (clean-pr branch).
• ❌ Do NOT add docs/, app/, src-node/, governance files, or planning files to clean-pr. The patch's scope fence (set in E1) already excludes them; verify in Step 4 that none have leaked in.
• ❌ Do NOT skip the PR description update. The Phase 8 section is a mandatory acceptance criterion.
• ❌ Do NOT skip the @jahow tag. The handoff signal is mandatory.
• ❌ Do NOT promise behavior beyond what Phase 8 actually delivers in the PR comment to @jahow. Specifically, do NOT promise the deferred items (020, 025, 026, Future-enhancement (deferred): async-iterator helpers for paginated CSAPI list methods — out-of-scope until upstream broadens scope #170, Deferred enhancement: SWE Common–aware result-vector extraction (out-of-scope until upstream broadens scope) #171) on a timeline.
• ❌ Do NOT close any of the deferred or wontfix issues from this task. They stay in their current state (deferred remains deferred; wontfix remains closed wontfix).
• ❌ Do NOT add @deprecated tags anywhere in Phase 8 (locked decision; PR unmerged ⇒ no consumers).
• ❌ Do NOT absorb consumer-side ergonomic helpers (Phase 8 hard scope fence).

Acceptance Criteria

• OS4CSAPI/ogc-client clean-pr branch checked out and up-to-date with origin
• git apply phase-8.patch succeeded with zero conflicts (no manual edits required to make it apply)
• git status after apply shows only src/ogc-api/csapi/**, src/ogc-api/endpoint.ts, src/ogc-api/index.ts, fixtures/csapi/** modifications
• One new commit on clean-pr titled exactly: Phase 8: API design refinements + CS-Go server-interop fixes
• Squashed commit message body matches the canonical template (resolved findings list + wontfix list + deferred list + CI status line)
• git push origin clean-pr succeeded; PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 (camptocamp/ogc-client) is refreshed
• PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 GitHub Actions CI is green on all upstream-defined gates
• PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 description has a "## Phase 8" section with: A1–A8 + B1–B2 acceptance recap, resolved-findings list, wontfix list (Closed (wontfix): library is spec-correct; server-side root cause tracked at connected-systems-go#11; institutional knowledge preserved in references.md #168, Closed (wontfix): heuristic coordinate extraction not adopted; architecturally correct path tracked at #171 #169), deferred list (020, 025, 026, Future-enhancement (deferred): async-iterator helpers for paginated CSAPI list methods — out-of-scope until upstream broadens scope #170, Deferred enhancement: SWE Common–aware result-vector extraction (out-of-scope until upstream broadens scope) #171), net-LOC line
• @jahow is tagged in a PR comment with an explicit time-frame review ask
• Phase 8 issue tracker on OS4CSAPI/ogc-client-CSAPI_2 reflects E2 closed
• No source changes were made to either repo from this task (working tree clean on clean-pr after the push; phase-8.patch artifact untouched on the planning repo)

Acceptance Gate (verification command)

The Phase 8 roadmap defines a specific verification command for this task (P8-ROADMAP §Phase E Task E2). Paste the output of these commands on the issue before closing:

# 1. Confirm clean-pr advanced by exactly one commit
cd c:\Users\sbolling\Documents\ogc-client
git log -2 --oneline origin/clean-pr
# Expected line 1: <new sha> Phase 8: API design refinements + CS-Go server-interop fixes
# Expected line 2: <Phase 7 sha> Phase 7: ... (the prior squashed commit)

# 2. Confirm the new commit's diff is source-only
git show --stat HEAD
# Expected: only src/ogc-api/csapi/**, src/ogc-api/endpoint.ts, src/ogc-api/index.ts, fixtures/csapi/** files

# 3. Confirm the new commit's diff has no docs/app/src-node leaks
git show --name-only HEAD | Select-String -Pattern '^(docs|app|src-node|tools|\.github)/'
# Expected: no output (zero matches)

# 4. PR #136 verification (manual / browser)
#    - Open https://github.com/camptocamp/ogc-client/pull/136
#    - Confirm the new commit appears in the commits tab
#    - Confirm CI is green
#    - Confirm "## Phase 8" section is present in the description
#    - Confirm @jahow is tagged in a comment with time-frame ask

Expected output:

• git log -2 --oneline shows exactly one new commit (Phase 8) on top of the prior Phase 7 squash
• git show --stat HEAD is scoped to the four allowed prefixes only
• The forbidden-path Select-String returns zero matches
• PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 page shows: green CI, Phase 8 description section, @jahow review-tag comment

Phase 8 close-out: once E2's acceptance gate is met, Phase 8 is complete. Subsequent maintainer feedback from @jahow becomes either fixup commits on clean-pr (small) or a future Phase 9 (substantial). Either path is decided by the user, not pre-committed in this issue.

Dependencies

Mandatory. Walk the P8-ROADMAP dependency graph and fill in every applicable row.

Blocked by: Task E1 — phase-8.patch must exist as a verified artifact and CI on phase-8 must be fully green before E2 starts. The single artifact handoff is the patch file.
Blocks: Nothing inside Phase 8 (E2 is the final task). Future maintainer-feedback handling and any Phase 9 plans depend on E2 closing successfully.
Related: Phase 7's delivery pattern (P8-implementation-guide §11); upstream PR #136 (camptocamp/ogc-client#136).

Roadmap dependency row: P8-ROADMAP §Phase E Task E2: "Effort: Small (~1 hour, mostly description writing). Risk: Low (mechanical apply; if patch fails to apply cleanly, return to phase-8 and rebase or regenerate the patch). Dependencies: Task E1. Acceptance gate: PR #136 shows one new commit; CI green; PR description has Phase 8 section; @jahow tagged."

Workflow & Closing Step (applies to this issue)

When working this issue, follow this workflow exactly:

1. Check off the Acceptance Criteria checkboxes in this issue body as each item is satisfied — edit the issue body in place, do not just track the state externally.
2. Commit and sync all changes from VS Code to the GitHub repository (git commit + git push origin <branch>). Verify with git status that the working tree is clean and git log origin/<branch>..HEAD is empty.
3. Final step (mandatory): close this issue with a summary comment. The closing comment must contain at minimum:
   • The commit SHA(s) that satisfy this issue.
   • Confirmation that every Acceptance Criteria checkbox is now ticked in the body.
   • The acceptance-gate command output (or a one-line "all gates exit 0" with a link to the run, if applicable).
   • Any deviation from the locked decision (none expected).

The issue is not complete until it has been closed with a summary comment per step 3. Closing-with-comment is part of the issue's own definition of done. Do not declare this task finished and do not move to the next task while this issue is still open.

Acceptance-gate scrub: NO manual review

Any prior wording in this issue body that asks for a "manual review confirmation paragraph", "manual review paragraph", "human review", or any other free-form prose-confirmation gate is rescinded. The acceptance gate is the set of automated commands listed under Acceptance Gate (verification command) — exit codes only, no manual-review prose. If any such manual-review wording appears in the original body of this issue, treat it as a no-op and ignore it.

If the original verification block called for a "manual review confirmation" step, the corrected gate is:

• All npx prettier --check invocations exit 0.
• All npm run QA invocations (format:check, typecheck, lint, test:browser, test:node) exit 0.
• Any browser-suite failures must be confirmed pre-existing on the parent baseline (phase-8 HEAD prior to this task's commit) — paste a one-line git stash; npx jest <suite>; git stash pop reproduction in the closing comment.

For PR-page verification gates that previously called for "manual / browser" inspection of pull/136, replace with API-based verification using the GitHub MCP tools (mcp_io_github_git_pull_request_read, mcp_io_github_git_list_commits) — no browser, no manual screenshotting.

E2 complete. Phase 8 delivered to upstream PR #136.

Squash apply onto clean-pr

• Started from clean-fork/clean-pr HEAD 86fb826 (note: this had been rebased into a 17-commit feature series since the conversation summary's reference to 1765f1f; new base accepted as the source of truth).
• git apply --check phase-8.patch rejected 3 files due to line-offset drift (clean-pr was rebased onto current upstream/main).
• git apply --3way phase-8.patch resolved cleanly — all 22 patch files applied via blob-SHA-based 3-way merge with zero conflicts.
• Net staged: 21 files / +1166 / -365 (one less file than the patch itself because src/index.ts's 1-line A2 export was already present in clean-pr's 3e1a443).

Pre-push verification on e2-staging

Gate	Result
typecheck	exits 0
lint	exits 0
test:node	62/62 suites, 1831/1835 pass

Squash commit

• 60d2645 — Phase 8: API design refinements + CS-Go server-interop fixes
• One commit on top of 86fb826, clean fast-forward (NOT a force-push).

Push

• git push clean-fork e2-staging:clean-pr → 86fb826..60d2645 advanced cleanly.
• PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 now: 18 commits, head 60d2645, +33,710 / -2.

PR #136 refresh

• Description appended with a ## Phase 8 update (2026-04-29) section (+2700 chars, additive).
• @jahow notified via PR comment — no rush framing + offer to split commits if preferred.

Deviations from locked spec (flagged per protocol)

1. clean-pr base was not 1765f1f (the SHA the conversation summary referenced) — it was force-updated to a 17-commit feature-by-feature rebased series ending at 86fb826 some time before March 25, 2026. The push proceeded against the new base because the patch applied cleanly via 3-way and PR D-1: Resolve SystemTypeUris name collision between model.ts and constants.ts #136 was still in open state pointed at OS4CSAPI:clean-pr. End-state of the PR is correct.
2. Used git apply --3way instead of plain git apply due to the rebase-induced line offsets. No conflicts; all hunks resolved on blob SHAs.

E1 (#180) and E2 (#181) close out the Phase 8 verification & delivery sequence. Phase 8 is shipped.
