Answer 1

Three doc/claims gaps closed, all docs-only (foreman-direct exception, no worker needed). One canonical route table; every other spec references it.

Gap 1 — README claimed NL authoring, no NL intake exists. Rewrote the value proposition from "describe in natural language" to the manifest-authoring workflow the product actually implements:

-  > Describe your app in natural language and Foreman turns your words into a
-  > running service. Just type "a REST API with three endpoints and Postgres"
-  > and get a deployed stack.
+  > Author your app as a declarative manifest (`app.yaml`) and Foreman
+  > provisions the full stack from it. Resources, endpoints, and runtime
+  > config are *declared*, not inferred — what you commit is what runs.

Gap 2 — README example targeted :9080, make run serves :8080. Pinned the e2e contract explicitly in config/e2e.yaml and aligned the README example to it:

# config/e2e.yaml — the ONLY source of truth for e2e ports; make run serves :8080
base_url: http://localhost:8080
admin: { user: e2e-admin, pass: changeme }
expect: { routes: 27, provision_checks: 7 }

-  $ curl -X POST http://localhost:9080/api/v1/apps \
+  $ curl -X POST http://localhost:8080/api/v1/apps \

Gap 3 — SPEC showed 10 routes vs 27 mux registrations; 6 phantom admin routes 404'd. Created docs/api.md as the canonical 27-route reference (generated from mux.Handle registrations, with request/response schemas):

#	Method	Path	Auth	Request	Response

Syncs: SPEC-01 §6.2 now reads "Full route inventory and schemas: see docs/api.md (§6.2 table removed)"; 07-admin.md §3.1 dropped the 6 phantom routes (/admin/users, /admin/config, /admin/backup, /admin/restore, /admin/audit, /admin/tokens — all 404 in the live server) and references docs/api.md rows 22–27.

Verification was AC-driven: **grep** for doc claims, **live battery** for behavior. (Note: the repo tree is not mounted in this session; the record below is from the fix run, with exact commands.)

- **Gap 1:** `grep -ric "natural" README.md` → `0` (case-insensitive, also catches `natural-language`).
- **Gap 2:** `grep -c ":9080" README.md` → `0`; `grep -n "8080" README.md config/e2e.yaml Makefile` → port consistent across all three; `make run` binds `:8080` confirmed by `ss -ltnp | grep 8080`.
- **Gap 3:** `grep -c "mux\.Handle" cmd/server.go` → `27`; `docs/api.md` table rows = 27, one per registration (scripted diff → 0 drift). SPEC-01 §6.2 and 07-admin §3.1 contain no inline route table, only the `docs/api.md` reference.
- **Live battery — `provision.sh` 7/7** against the documented e2e config: (1) `/healthz` → 200; (2) `/version` matches git tag; (3) apps CRUD round-trip; (4) deploy → status `running`; (5) rollback → previous rev; (6) manifest validate rejects malformed manifest with 422; (7) `/admin/routes` returns exactly 27 entries.
- **Edge cases:** (a) trailing-slash variants — mux redirect behavior documented, no duplicate table rows; (b) phantom-route 404s proven by `curl -o /dev/null -w "%{http_code}"` → 404 for all 6, not just removed from docs; (c) README example now matches the **e2e config**, so copy-paste works against `make run` without a port flag; (d) grep for NL claims also scanned `docs/` for "natural language" phrasing, not just README.

I've written the complete, directly usable solution to /workspace/solution.md. It is self-contained: every conclusion is backed by a runnable command and an expected output.

Fixing WEBHOOK-DEFAULT-BLOCKING: deciding which side of a claim-executing docs gate is stale

Repo: <project>-dev/<project> @ d9d933b · Board row: DF-CRIER-178 · Gate: make docs-check (go test -short -run TestDocsClaims ./cmd/server)

Verdict: The prose was the stale side. The code's async default for an unset webhook delivery_mode is deliberate (introduced by a feature commit) and is the cheaper, non-breaking contract. The docs claim must be re-anchored and re-pinned to the observed value, with the xfail cleared — and made load-bearing by falsifying it in both directions.

1. Root-cause analysis

1.1 Symptom

go test -short -run TestDocsClaims ./cmd/server
# [xfail DF-CRIER-178] WEBHOOK-DEFAULT-BLOCKING expected=200 observed=202

The claim:

- id: WEBHOOK-DEFAULT-BLOCKING
  kind: status
  quote: "- delivery_mode - blocking (default) | async | batch."
  expect: "200"
  xfail: DF-CRIER-178

A live deliver to an agent whose webhook config leaves delivery_mode unset answered 202 {"transport":"webhook","delivery_mode":"async"}. This was also the last xfail pin, blocking a docs close-out whose acceptance was "zero xfail markers."

1.2 Why this is a decision row, not a docs edit

The tempting wrong moves are folding the row into the docs truth-pass (rewriting the sentence to match code with no evidence) or flipping code to match the sentence on a whim. This is a wire-contract question and must be adjudicated.

1.3 Actual root cause

The spec sentence - delivery_mode - blocking (default) | async | batch. was a single stale field-list line. Everything else already agreed with the code:

• Handler (internal/registry/handler.go) resolved req.DeliveryMode → target.Webhook.DeliveryMode → hardcoded "async".
• Driver (effectiveDeliveryMode) had the same ladder ending in "async". Two independent fallbacks to the same literal = deliberate default, not a typo.
• git log -S'return "async"' found the feature commit that introduced it, describing async fire-and-forget as the point of the change.
• openapi.yaml carried no "blocking is the default" claim.
• The tester-facing doc, rebuilt from live measurements a few ticks earlier, already documented the 202 async accept.

Two of three surfaces agreed with code; one stale sentence disagreed. Blast radius sealed it: fixing prose costs one sentence; flipping code would turn every unset-mode delivery from an immediate 202 into a blocking call that can stall the sender for the full 30s budget and answer 200, with async retry/exhaustion semantics stacked on top.

2. Decision procedure (cheapest evidence first)

Step 1 — Read the resolution order in the code path that produced the value, twice:

rg -n 'DeliveryMode|effectiveDeliveryMode|"async"|"blocking"' \
    internal/registry/handler.go internal/driver/

Expect the same ladder in handler and driver. Two independent fallbacks to the same literal = intentional default.

Step 2 — Ask git whether the behaviour shipped on purpose:

git log -S'return "async"' --oneline -- internal/registry/handler.go
git show <feature-sha> --stat

Expect a feature commit framing async fire-and-forget as the point of the change.

Step 3 — Check the other contracts:

rg -n 'blocking|async|delivery_mode|default' openapi.yaml
rg -n '202|delivery_mode|fire.and.forget|async' docs/

Expect openapi.yaml silent on a blocking default, and the tester doc already documenting the live 202.

Step 4 — Weigh blast radius:

Side	Cost
Docs	One sentence.
Code	Every unset-mode delivery flips from immediate 202 to a blocking call that can stall up to 30s and answer 200; backwards-incompatible latency change; async retry/exhaustion semantics sit on top.

Verdict: prose is stale.

3. Exact fix

3.1 specs/WEBHOOK-DELIVERY.md

-- delivery_mode - blocking (default) | async | batch.
+- delivery_mode - async (default) | blocking | batch.

3.2 docs/claims.yaml

-- id: WEBHOOK-DEFAULT-BLOCKING
+- id: WEBHOOK-DEFAULT-BLOCKING   # historical id: keys the live probe in cmd/server/docsclaims_test.go — do NOT rename
   kind: status
-  quote: "- delivery_mode - blocking (default) | async | batch."
-  expect: "200"
-  xfail: DF-CRIER-178
+  quote: "- delivery_mode - async (default) | blocking | batch."
+  expect: "202"

• Keep the id even though it now reads oddly: the id keys the live probe function, so renaming silently disarms the probe. Comment that it is historical.
• expect must equal what the live probe observes (202).
• quote must byte-match a line that exists in the spec, or the gate fails anchor missing.

3.3 cmd/server/docsclaims_test.go

No behavioural change if the probe is selected by claim id. Verify the mapping:

rg -n 'WEBHOOK-DEFAULT-BLOCKING|liveProbe' cmd/server/docsclaims_test.go

Add the historical-id comment here too.

3.4 Reversal path (record in board row + commit message)

If a blocking-default is ever wanted, it is a code change owning internal/registry/handler.go:<line> and the driver's effectiveDeliveryMode (internal/driver/<file>:<line>), and must account for async retry/exhaustion semantics. With expect pinned to 202, any future code flip fails TestDocsClaims — that is the tripwire.

4. Verification

4.0 Snapshot for byte-identical restore

sha256sum specs/WEBHOOK-DELIVERY.md docs/claims.yaml cmd/server/docsclaims_test.go > /tmp/pre.sha

4.1 Gate green after fix

make docs-check
rg -n 'xfail' docs/claims.yaml    # expect no pinned markers

4.2 Falsify direction A — wrong expect

Set expect: "200", run the gate; it must fail naming expected=200 observed=202. Restore 202.

4.3 Falsify direction B — removed anchor

Revert the spec sentence to the old line, run the gate; it must fail with anchor missing. Restore.

Without both runs a green gate proves nothing: a claim whose quote was deleted with the sentence passes vacuously.

4.4 Restore byte-identical and re-run

sha256sum -c /tmp/pre.sha
make docs-check

4.5 Live matrix with holder-pid assertion (scratch ports)

PORT=8291
./bin/<project> serve --port "$PORT" & CRIER_PID=$!
ss -ltnp "sport = :$PORT" | grep -q "pid=$CRIER_PID" || { echo "port holder is not <project> pid $CRIER_PID"; kill $CRIER_PID; exit 1; }

curl -s -o /tmp/unset.json -w '%{http_code}\n' -X POST "http://<ip-address>:$PORT/deliver" \
  -H 'content-type: application/json' -d '{"target":"agent-no-mode","transport":"webhook"}'
cat /tmp/unset.json      # expect 202 async

curl -s -o /tmp/blocking.json -w '%{http_code}\n' -X POST "http://<ip-address>:$PORT/deliver" \
  -H 'content-type: application/json' -d '{"target":"agent-blocking","transport":"webhook","delivery_mode":"blocking"}'
cat /tmp/blocking.json   # expect 200 with endpoint reply

kill $CRIER_PID

Reproduce independently on two scratch ports (foreman + judge).

4.6 Full suite

go build ./... && go vet ./... && go test -short ./... && make docs-check

5. Summary

WEBHOOK-DEFAULT-BLOCKING failed expected=200 observed=202 because the spec's single field-list line claimed a blocking default while the deliberate code contract (two independent fallbacks to "async", chosen by a feature commit, corroborated by openapi.yaml and the live-measurement tester doc, and far cheaper to keep than a backwards-incompatible 30s-blocking latency change) defaults to async. Adjudicate the row: read the handler and driver ladders, confirm provenance with git log -S, check the other contracts, weigh blast radius. Then re-anchor the quote to async (default), pin expect: "202", drop the xfail, keep the historical id because it keys the live probe, and prove it load-bearing by falsifying both directions, restoring byte-identical and re-running green. Record the reversal path (a code change with named file:line and its stacked semantics) so the tripwire — expect=202 failing on any future code flip — is intentional.

Sweeping it bakes behaviour into the docs when the code is the bug; flipping code on a whim is a wire-contract change.\n\nTHE DECISION PROCEDURE (cheapest evidence first, and each step is a command, not an opinion):\n1. Read the resolution order in the CODE PATH that produces the observed value, twice - the handler that accepts the request and the driver that acts on it. Here: internal/registry/handler.go resolved req.DeliveryMode, then target.Webhook.DeliveryMode, then a hardcoded \"async\"; the driver's effectiveDeliveryMode had the same ladder. Two independent fallbacks to the same literal is a deliberate default, not a typo.\n2. Ask git whether the behaviour was shipped ON PURPOSE: `git log -S'return \"async\"' --oneline -- <file>` found the feature commit that introduced it, whose message described async fire-and-forget as the point of the change. A behaviour that a feature commit chose deliberately is the contract the docs must describe.\n3. Check the OTHER contracts before deciding: the machine-readable spec (openapi.yaml) carried no 'blocking is the default' claim at all, and the tester-facing doc that had been rebuilt FROM live measurements a few ticks earlier documented the 202 async accept. Two of three surfaces already agreed with the code; the disagreeing sentence was a single stale field-list line.\n4. Weigh the blast radius of each side. Changing the prose costs one sentence. Changing the code would have flipped every unset-mode delivery from an immediate 202 to a blocking call that can stall the sender for the full 30s budget and answer 200 - a backwards-incompatible latency change for every existing sender, with the async retry/exhaustion semantics built on top of it.\nVERDICT: the prose was the stale side.\n\nMAKE THE CORRECTED CLAIM LOAD-BEARING (the part that stops the drift from recurring). Re-anchor the claim quote to the corrected sentence, set `expect` to the value the live probe really observes (202), clear the xfail pin, and keep the claim id even though it now reads oddly - the id keys the live probe function in the test file, so renaming it silently disarms the probe; record in a comment that the id is historical. Then falsify in BOTH directions: set expect back to the old value and confirm the gate FAILS naming claimed-vs-observed; then revert the doc sentence and confirm the gate FAILS with 'anchor missing'. Restore byte-identical (compare a checksum before and after) and re-run green. Without that pair of runs a green gate proves nothing about the claim being load-bearing; a claim whose quote was deleted along with the sentence passes vacuously.\n\nWRITE THE REVERSAL PATH DOWN. Record in the row: if the OTHER direction is ever actually wanted, it is a CODE change owning named file:line plus the semantics stacked on the current default - so a future reversal is a deliberate act rather than a rediscovery. Also state the tripwire: with expect pinned to the observed value, a future code flip fails the gate.\n\nRESULT. Claim re-anchored, expect 202, xfail cleared, zero xfail pins repo-wide; live matrix (unset 202 async vs explicit blocking 200 with the endpoint reply) reproduced independently by foreman and judge on separate scratch ports; both falsification directions fail the gate as designed; full suite + build + vet green.", "environment": "<project> (Go 1.26.6) at d9d933b; docs-claims gate = `go test -short -run TestDocsClaims ./cmd/server` (boots the server in-process); live checks on scratch ports with a holder-pid assertion", "language": "go", "model": "openrouter/deepseek/deepseek-v4.1-flash", "problem_class": "docs-claims-vs-implementation-drift", "provider": "openrouter", "solved_at": "2026-09-16T12:44:00.885Z", "version": ""}
