|
||||
const CONTRACT = `
|
||||
HEALTHCHECK CONTRACT — pinned, do not deviate or "improve":
|
||||
- Trigger: top-level direct-invoke payload only. In lambda handler ("handler"
|
||||
in handler.py), the VERY FIRST statements: if the event is a dict and
|
||||
event.get("healthcheck") is True -> return {"healthcheck": "ok"} immediately.
|
||||
- Placement: BEFORE any boto3/S3 use, BEFORE ses_auth, BEFORE iterating
|
||||
event["Records"]. It must not create any accept path for mail: real mail
|
||||
events are S3 ObjectCreated events whose top-level keys AWS controls
|
||||
("Records"); email content can never set a top-level event key.
|
||||
- Telemetry: the healthcheck branch emits NO EMF metrics and NO log line
|
||||
whose text could match the sender-auth-rejected metric-filter pattern
|
||||
(read the filter pattern in cdk/*_stack.py before choosing any log text;
|
||||
safest is a single log line exactly "healthcheck ok" or no logging).
|
||||
That alarm pages at >=1 match, so two deploys in ~30 min must not page.
|
||||
- SMOKE SCRIPT CONTRACT: scripts/post-deploy-smoke.sh invokes BOTH functions
|
||||
(po-email-processor, workorder-email-processor) with payload
|
||||
'{"healthcheck": true}' using: aws lambda invoke --invocation-type
|
||||
RequestResponse. It must check the FunctionError field of the response
|
||||
(an init ImportError returns HTTP 200 + FunctionError=Unhandled — exit-code
|
||||
checks false-pass) AND that the payload equals {"healthcheck": "ok"}.
|
||||
Non-zero exit on any failure; set -euo pipefail; region us-east-1.

|
||||
Task A: replace the four-file cp allowlist with a non-recursive glob:
|
||||
"cp ./*.py /asset-output/". Keep the pip install line untouched. Update the
|
||||
warning comment to explain the glob + that the AST test now enforces

consistency. PROVE identical output: list lambdas/po/email_processor/*.py
|
||||
(non-recursive) and confirm the set equals {handler, ses_auth,
|
||||
template_parser, derived_fields}.py plus any other top-level .py that SHOULD
|
||||
ship; if extras exist (e.g. prompts or __init__), state explicitly whether
|
||||
shipping them is a no-op and why. tests/ and package/ are directories, so a
|
||||
non-recursive ./*.py glob never matches them.
|
||||
Task B: write tests/test_bundle_consistency.py: for EACH pipeline (po, wo),

ast-parse email_processor/handler.py, collect top-level "import X" /

"from X import ..." names, filter to first-party siblings (X.py exists in the

same dir), and assert the bundling guarantee ships them — for PO: assert the

po_stack.py bundling command contains the glob "cp ./*.py"; for WO: assert
|
||||
its bundling command copies them (read wo_stack.py to see its current cp -r
|
||||
form and assert accordingly). The test must FAIL if someone reverts the glob
|
||||
to an allowlist missing a sibling — include a unit-level check that simulates
|
||||
an allowlist command string missing derived_fields.py and asserts the
|

detection logic catches it. No AWS/boto3/synth in the test — pure

|

PINNED BEHAVIORAL CONSTRAINTS (docs/refactor-evaluation.md Phase 2 — violating any is a build failure):
|
||||
1. ZERO diff under lambdas/: git diff ${BASE}...HEAD -- lambdas/ must be
|
||||
EMPTY. This phase moves NO code — only cdk/, tests/test_bundle_consistency.py,
|
||||
README.md (and docs/ if needed) may change.
|
||||
2. Both email processors: Code.from_asset("../lambdas") with the bundling
|
||||
command rewritten for the new cwd (bundling cwd IS the asset root):
|
||||
pip install ... -r po/email_processor/requirements.txt -t /asset-output &&
|
||||
cp po/email_processor/*.py /asset-output/ (resp. wo/email_processor).
|
||||
The -r path change is REQUIRED. PRESERVE the pip
|
||||
"--platform manylinux2014_aarch64 --only-binary=:all:" pin exactly — its
|
||||
removal shipped x86 wheels into the ARM64 function and caused a 100%
|
||||
outage (PR #34); it is non-negotiable.
|
||||
3. Both widened from_asset calls get
|
||||
exclude=['**/__pycache__/**', '**/tests/**', '**/package/**'].
|
||||
from_asset does NOT honor .gitignore; without the package/ exclude the
|
||||
stale untracked 44 MB lambdas/po/email_processor/package/ dir diverges
|
||||
LOCAL vs CI asset hashes (CI never has it) and forces spurious redeploys.
|
||||
4. WO prod-zip shrinkage is DELIBERATE cleanup, not an accident to fix: the
|
||||
current 'cp -r .' ships tests/ (real scrubbed .eml fixtures), __pycache__,
|
||||
and requirements.txt in the production zip. The acceptance criterion for
|
||||
WO is "runtime-imported module set unchanged + smoke", NOT byte-identical
|
||||
zip. Byte-identical first-party file set applies to PO ONLY. Document the
|
||||
shrinkage explicitly (list every file class that drops out).
|
||||
5. The three plain from_asset calls (po web_ui, po site_extractor, wo web_ui
|
||||
— locate them, line numbers have shifted since the doc) each gain
|
||||
exclude=['**/__pycache__/**'] so local __pycache__ stops making their
|
||||
asset hashes nondeterministic. Nothing else about them changes.
|
||||
6. tests/test_bundle_consistency.py must be updated IN THE SAME CHANGE — it
|
||||
deliberately change-detects both bundling commands and will fail red on
|
||||
the new shapes. Update it to recognize the scoped glob
|
||||
'cp po/email_processor/*.py' (resp. wo) as the new unconditionally-safe
|
||||
shape, WITHOUT loosening it: the allowlist-revert detection, the
|
||||
detection-logic mutation test, and the PO_EXPECTED_TOP_LEVEL_MODULES
|
||||
exact-set pin must all keep their teeth. A bare-substring match that any
|
||||
commented-out glob satisfies is a regression.
|
||||
7. cdk diff on BOTH stacks must show ONLY the two functions' Code/asset
|
||||
property changes (+ CDK metadata). No logical-ID changes, no alarm, IAM,
|
||||
table, env, or function-config deltas of any kind.
|
||||
8. Do NOT delete lambdas/po/email_processor/package/ (untracked, local-only;
|
||||
deletion is Adam's call — with the exclude in place it is hash-neutral).
|
||||
Do NOT touch requirements.txt contents (Phase 7 scope).
|
||||
9. AWS access is READ-ONLY (get-function, downloading the deployed zip via
|
||||
its presigned URL). NEVER cdk deploy, never invoke, never mutate.

1. cd cdk && npx cdk synth po-ingest -q -o /tmp/phase2-synth && npx cdk

2. Re-download both deployed zips (aws lambda get-function Code.Location,

|
||||
PINNED BEHAVIORAL CONSTRAINTS (docs/refactor-evaluation.md Phase 6 + §4 item 6 — violating any is a build failure):
|
||||
1. THE DEFECT is in lambdas/po/site_extractor/handler.py: extract_site_code
|
||||
(line 34) already prefers record["site_code"] (line 36), but validates it
|
||||
with SITE_CODE_PATTERN = re.compile(r"[A-Z]{2,4}\\d{1,2}") (line 23) applied
|
||||
via .match (prefix-anchored, digit-REQUIRING). That pattern REJECTS
|
||||
all-letter codes like KLAL — so a KLAL-class site can NEVER self-register
|
||||
and becomes a permanent pending-review row — and ACCEPTS overlong junk like
|
||||
DLI6X / SNY55 (prefix match, no end anchor). THE FIX: validate the direct
|
||||
record["site_code"] field with the CANONICAL derived_fields shape + skip-list
|
||||
semantics using FULLMATCH (derived_fields.py: _STRICT_CODE_RE at line 50 =
|
||||
re.compile(r"[A-Z][A-Z0-9]{2,4}") + _is_valid_code at line 97 = "not in _SKIP
|
||||
and >=2 alphabetic chars", _SKIP at line 69). Import derive_site_code
|
||||
(derived_fields.py:259) for the FALLBACK path (ship_to / line_items). DELETE
|
||||
the bespoke regex ladder — the line 62 alternation
|
||||
r"^([A-Z]{1,4}[0-9]{1,2}|[A-Z]{4,5})\\b" whose [A-Z]{4,5} arm is dead code
|
||||
(it can never survive the digit-requiring SITE_CODE_PATTERN.match on the very
|
||||
next line) — and every other SITE_CODE_PATTERN reference. NET EXPECTED
|
||||
BEHAVIOR: KLAL is ACCEPTED, DLI6X and SNY55 are REJECTED.
|
||||
2. SHIP derived_fields.py INTO the site_extractor Lambda asset. Add the cp/root
|
||||
bundling change for site_extractor's from_asset in cdk/po_stack.py (currently
|
||||
lines 684-686: Code.from_asset("../lambdas/po/site_extractor",
|
||||
exclude=["**/__pycache__/**"]) — Phase 3 left this UNTOUCHED on purpose).
|
||||
THIS phase makes lambdas/po/email_processor/derived_fields.py reachable there,
|
||||
MIRRORING the Phase 2/3 mechanism the two email processors use (widened
|
||||
asset root + a scoped cp so the module lands FLAT in /asset-output so the
|
||||
bare-name import 'from derived_fields import derive_site_code' resolves).
|
||||
KEEP the __pycache__ / tests excludes intact; do NOT ship tests/ or a stale
|
||||
package/ into the zip. The spec agent pins the exact root + cp form (Docker
|
||||
bundling vs a no-Docker local staging — ONE mechanism, exact code).
|
||||
3. Keep shape/skip validation ON the record["site_code"] field even though it
|
||||
is ai_fallback-SOURCED (the LLM value is authoritative during/after the bake)
|
||||
— this is validated authority, NOT blind trust and NOT a regex bypass. Keep
|
||||
parse_address (line 69) AND the pending-review write flow (write_pending_review
|
||||
line 223 + the handler else-branch lines 283-290) BYTE-UNCHANGED.
|
||||
4. Repoint scripts/backfill_sites.py at derive_site_code (it currently does
|
||||
'from handler import extract_site_code, parse_address, upsert_site' via a
|
||||
sys.path hack) — OR DELETE it entirely (one-time backfill script; deletion is
|
||||
acceptable and PREFERRED if simpler). Pick one and state why.
|
||||
5. CHARACTERIZATION TESTS FIRST. site_extractor is 0% covered today (§2). Write
|
||||
tests that PIN CURRENT behavior first — INCLUDING the KLAL rejection
|
||||
divergence and the overlong-junk (DLI6X / SNY55) acceptance, parse_address
|
||||
variants, and the pending-review fallback — then FLIP the assertions to the
|
||||
FIXED behavior in the SAME PR, so the change is provably intentional. The
|
||||
final committed suite asserts FIXED behavior (KLAL accepted, DLI6X/SNY55
|
||||
rejected); the characterization-of-old-behavior stage is a build step, not a
|
||||
red suite left behind.
|
||||
6. derived_fields.py itself stays UNTOUCHED — import it, do NOT edit it.
|
||||
git diff ${BASE}...HEAD -- lambdas/po/email_processor/derived_fields.py MUST
|
||||
be empty. The shadow-bake authority model must not shift in this phase.
|
||||
7. AWS access is READ-ONLY (get-function, downloading the deployed site_extractor
|
||||
zip via presigned URL to confirm the asset contents). NEVER cdk deploy, never
|
||||
invoke, never mutate. No push, no PR, no cdk deploy in this workflow.

its r"^([A-Z]{1,4}[0-9]{1,2}|[A-Z]{4,5})\\b" alternation — prove the

byte-unchanged; note everything that must NOT move.

_is_valid_code (line ~97) verbatim with file:line. State exactly what shape

counts as a valid site code (3-5 chars, letter-first, all-letters allowed,

|

the handler passes the right shape of dict.

3. Determine precisely: under the canonical fullmatch shape + _is_valid_code,

is required to hit the doc's pinned outcome (KLAL accepted; DLI6X/SNY55

4. List every import derived_fields.py needs at module load (must be

REJECTED — if recon found the bare fullmatch shape does not reject

DLI6X/SNY55, pin the exact additional check that does (do NOT reintroduce a

digit requirement). Import derive_site_code from derived_fields for the

fallback path; wire it with the correct input shape. DELETE the

SITE_CODE_PATTERN def, the line-62 alternation, and every SITE_CODE_PATTERN

widened root + scoped cp staging both site_extractor *.py and

lambdas/po/email_processor/derived_fields.py FLAT into /asset-output, with

const CONSTRAINTS = `
|
||||
PINNED BEHAVIORAL CONSTRAINTS (docs/refactor-evaluation.md Phase 7 — violating any is a build failure):
|
||||
1. GENERALIZE scripts/reprocess.py: add --pipeline po|wo (selects the
|
||||
function name + bucket per pipeline — po-email-processor /
|
||||
po-ingest-emails-<acct>, workorder-email-processor / its bucket), plus
|
||||
--key (single object), --prefix, and --since (time filter on
|
||||
LastModified). TARGETED replay (--key / --prefix / --since) is the
|
||||
PRIMARY, default mode. FULL-PREFIX replay is DEMOTED behind an explicit
|
||||
--all flag. The --all caveats MUST be documented BOTH in --help text and
|
||||
in code comments: Event-type (async) invocation is CONCURRENT so sorting
|
||||
does NOT serialize; switch to RequestResponse if order matters; metrics
|
||||
get double-counted on replay; Bedrock is re-billed; out-of-order replay
|
||||
can REGRESS already-merged fields. Keep the existing dry-run-by-default /
|
||||
--execute safety (targeted replay stays dry-run unless --execute).
|
||||
2. SYNTHETIC-EVENT-SHAPE CONTRACT TEST (§4.7): pin the exact S3 event shape
|
||||
reprocess emits — Records[0].s3.bucket.name + Records[0].s3.object.key —
|
||||
and assert the key is the RAW object key with NO URL-decoding (a real S3
|
||||
notification URL-encodes the key; reprocess builds from the raw
|
||||
list_objects_v2 key, and the handler is what decodes — replaying a
|
||||
pre-decoded key would double-decode). Test lives under scripts' tests or
|
||||
tests/ and runs in the standard pytest collection.
|
||||
3. NEW docs/runbook-dlq-recovery.md: the async on-failure destination DLQ
|
||||
has NO console redrive-to-source. Documented procedure: receive-message
|
||||
-> extract the S3 key from the event body -> targeted re-invoke (via the
|
||||
generalized reprocess.py --key) -> verify the write -> purge the message.
|
||||
State the recovery WINDOWS explicitly: 14-day DLQ breadcrumb retention,
|
||||
90-day raw-email S3 retention (the inbound/ lifecycle rule OVERRIDES the
|
||||
table RETAIN policy — S3 is the real replay floor). Document that
|
||||
sender-auth rejections AND ai_fallback_rejected drops INTENTIONALLY never
|
||||
reach the DLQ (they are fail-closed SKIPS, not errors — no retry, no DLQ
|
||||
message). Link the runbook from the README alarms section.
|
||||
4. DEPENDENCY HYGIENE — DROP vendored boto3 from BOTH email-processor
|
||||
requirements.txt: replace 'boto3>=1.43.47' with the handbook
|
||||
empty-with-comment form (a comment explaining the Lambda runtime provides
|
||||
boto3 per lambda-template.md — only-boto3 functions correctly use the
|
||||
runtime copy; no pinned third-party dep remains). Same empty-with-comment
|
||||
reduction for wo/web_ui/requirements.txt (a dead manifest today).
|
||||
5. SIMPLIFY BUNDLING TO CP-ONLY where the vendored dep is gone: once the
|
||||
email-processor requirements are empty-with-comment, 'pip install -r ... '
|
||||
installs nothing, so the pip step is removable and the command becomes
|
||||
cp-only. This is ONLY safe BECAUSE there are no third-party binary deps
|
||||
left. Do NOT regress: the Phase 2 exclude lists
|
||||
(['**/__pycache__/**','**/tests/**','**/package/**']) STAY; the widened
|
||||
'../lambdas' asset root STAYS; if a Phase 3 'cp shared/*.py' line is
|
||||
present on the base it STAYS. The '--platform manylinux2014_aarch64
|
||||
--only-binary=:all:' pin is only meaningful while a pip install runs — its
|
||||
accidental removal caused the PR #34 outage, so removing the WHOLE pip
|
||||
step (deliberately, because nothing is installed) is the only acceptable
|
||||
way it disappears; you may NOT keep a pip install while dropping the pin.
|
||||
If recon finds ANY third-party dep still required by an email processor,
|
||||
cp-only is a blocker — keep the pinned pip step.
|
||||
6. EXACT-PIN moto: change tests/requirements.txt 'moto>=5.0.0' to
|
||||
'moto==<resolved-version>' (resolve the actually-installed/current 5.x
|
||||
version; floor pins make the dependabot entry a no-op).
|
||||
7. DEPENDABOT: add pip entries for '/tests', '/lambdas/po/web_ui', and
|
||||
'/lambdas/po/site_extractor' — but PIN THOSE MANIFESTS FIRST. po/web_ui
|
||||
and po/site_extractor have NO requirements.txt today, so a dependabot
|
||||
entry pointed at them is a no-op until a PINNED manifest exists; create
|
||||
each manifest (exact-pinned boto3, or empty-with-comment ONLY if the
|
||||
dependabot entry would then be pointless — a dependabot entry needs at
|
||||
least one pinned dep to act on). Match the existing dependabot.yml entry
|
||||
shape (weekly, minor-and-patch group). tests/ gets its entry once moto is
|
||||
exact-pinned (constraint 6).
|
||||
8. DELETE the untracked 44 MB lambdas/po/email_processor/package/ dir as an
|
||||
OPTIONAL local-cleanup step: it is UNTRACKED / local-only, so this is a
|
||||
filesystem 'rm -rf', NOT a 'git rm' (there is nothing tracked to commit).
|
||||
With Phase 2's '**/package/**' exclude already deployed, the deletion is
|
||||
asset-hash-NEUTRAL. The Package agent PERFORMS and REPORTS it; it is NOT
|
||||
part of the commit.
|
||||
9. UNTOUCHABLE: no handler / lambda runtime code change under lambdas/*/
|
||||
email_processor/*.py (this is dep + ops + bundling only). No alarm, IAM,
|
||||
table, env, runtime, memory, timeout, or logical-ID delta on either stack
|
||||
— the ONLY cdk delta permitted is the bundling command string on the two
|
||||
email processors (+ any resulting asset-hash / CDK metadata change). The
|
||||
dropped-vendored-boto3 functions MUST still 'import boto3' at runtime from
|
||||
the Lambda runtime copy.
|
||||
10. AWS access is READ-ONLY (get-function, get-function-event-invoke-config,
|
||||
SQS get-queue-attributes, S3 get-bucket-lifecycle-configuration,
|
||||
describe-alarms). NEVER cdk deploy, never invoke, never mutate, never
|
||||
purge a real queue.

established, so this phase must NOT race Phase 2. git fetch origin, then

Read-only recon of scripts/reprocess.py and the event shape it must pin:
|
||||
1. Quote scripts/reprocess.py verbatim with file:line — the argparse surface
|
||||
today (--execute only), FUNCTION_NAME, get_bucket_name (po-only,
|
||||
po-ingest-emails-<acct>), list_inbound_keys (paginator, Prefix='inbound/'),
|
||||
build_s3_event (the exact Records/s3/bucket.name/object.key shape), the
|
||||
Event (async) InvocationType.
|
||||
2. Find the WO analogues so --pipeline wo can resolve: the workorder
|
||||
email-processor function name and its email bucket naming (grep the cdk
|
||||
stacks / function_name / bucket_name). State them exactly.
|
||||
3. Determine how the email-processor handler reads the key from an S3 event:
|
||||
does it URL-decode Records[].s3.object.key (urllib.parse.unquote_plus)?
|
||||
Quote the handler line. This decides the contract test's no-double-decode
|
||||
assertion (reprocess must emit the RAW key so the handler decode path is
|
||||
exercised exactly once — a pre-decoded key double-decodes '+'/'%20').
|
||||
4. Is there ANY existing test that touches scripts/reprocess.py? (grep tests/
|
||||
and scripts/). Where should the new synthetic-event contract test live so
|
||||
it is collected by the standard pytest run (repo-root pytest collects
|
||||
tests/ and both email_processor tests/ roots)? Note whether scripts/ is on

Read-only recon of the dependency / manifest / dependabot state:
|

1. Quote every requirements.txt under lambdas/ and tests/ verbatim with path:

lambdas/po/email_processor (boto3>=1.43.47), lambdas/wo/email_processor
|
||||
(boto3>=1.43.47), lambdas/wo/web_ui (boto3>=1.43.47 — dead manifest),

tests/ (moto>=5.0.0), cdk/. Confirm po/web_ui and po/site_extractor have
|
||||
NO requirements.txt (they must be CREATED + pinned before a dependabot
|
||||
entry is not a no-op).
|
||||
2. Resolve the moto version to exact-pin: what 5.x is actually installed /
|
||||
currently resolves (pip show moto or the lockfile / venv)? State the exact
|
||||
version string to pin.
|
||||
3. Quote .github/dependabot.yml verbatim: the existing pip entries (/cdk,
|
||||
/lambdas/po/email_processor, /lambdas/wo/email_processor, /lambdas/wo/web_ui)
|
||||
and the github-actions entry — the exact shape (weekly interval,
|
||||
minor-and-patch group) the three NEW entries must match.
|
||||
4. Confirm via lambda-template.md (handbook) the exact empty-with-comment
|
||||
form for only-boto3 functions (the Lambda runtime provides boto3) — quote
|
||||
the canonical comment wording so the edits match the handbook.
|
||||
5. Does anything under lambdas/*/email_processor actually import a THIRD-PARTY
|
||||
package other than boto3 (grep imports; anthropic/requests/etc.)? If yes,
|

cp-only is unsafe — that is a blocker for constraint 5.

Read-only recon of the post-Phase-2 CDK bundling + the package/ dir:
|
||||
1. Quote BOTH email-processor Code.from_asset blocks verbatim with current
|
||||
file:line (cdk/po_stack.py ~241, cdk/wo_stack.py ~240): asset root, the
|
||||
FULL exclude list, the entire bundling command list — the pip install

'--platform manylinux2014_aarch64 --only-binary=:all: -r

<pipeline>/email_processor/requirements.txt -t /asset-output' step, the

|
||||
whether a Phase-3 'cp shared/*.py /asset-output/' line is already present
|
||||
on this branch's base. Note the explanatory NOTE comment in po_stack.
|

2. State the exact cp-only rewrite for each (drop the pip step entirely,
|
||||
keep every cp line + the widened root + the exclude list). Confirm the
|
||||
pip step is the ONLY thing removed.
|
||||
3. The three plain from_asset calls (po/web_ui, po/site_extractor,
|

wo/web_ui) — quote them; they are NOT bundling-simplified here (no pip
|
||||
step), just confirm they are untouched by this phase.
|

4. lambdas/po/email_processor/package/ — du -sh it, confirm it is UNTRACKED

'**/package/**' exclude already keeps it out of the asset hash (so its

Read-only AWS + docs recon for the runbook (region us-east-1, READ-ONLY):

1. Both email-processor DLQs: exact SQS queue names/ARNs and the

via the stacks (dead_letter_queue / make_processor_dlq) and

aws sqs get-queue-attributes. Also the async event-invoke config /

that overrides the table RETAIN policy (S3 is the replay floor).

those two drop classes are fail-closed SKIPS that never reach the DLQ.

You are the SPEC agent — the single authority that pins every contested

other's choices). Using the recon pack below plus your own reads of the

actual files, produce the binding implementation spec:

- reprocessCli: the complete generalized scripts/reprocess.py — argparse
|
||||
surface (--pipeline po|wo required; --key / --prefix / --since targeted
|
||||
modes; --all for full-prefix; --execute preserving dry-run-by-default),
|
||||
the per-pipeline function-name + bucket resolution table, and the EXACT
|
||||
--help + in-code caveat text for --all (all five caveats from constraint 1
|
||||
verbatim). TARGETED is the default path; --all is the ONLY way to sweep the
|
||||
whole prefix.
|
||||
- contractTest: the synthetic-event-shape test — file path (collected by the
|
||||
standard pytest run), the assertions on Records[0].s3.bucket.name and
|
||||
object.key, and the raw-key / no-URL-decoding assertion with a concrete
|
||||
encoded-vs-raw example (e.g. a key with a space or '+').
|
||||
- runbook: the full docs/runbook-dlq-recovery.md outline with the real
|
||||
DLQ/queue/alarm/bucket names from recon, the no-redrive procedure steps
|
||||
(receive -> extract S3 key from event body -> targeted re-invoke via
|
||||
reprocess.py --key -> verify -> purge), the 14d-DLQ / 90d-S3 windows +
|
||||
lifecycle-overrides-RETAIN note, the intentional sender-auth +
|
||||
ai_fallback_rejected non-DLQ statement, and the exact README alarms-section
|
||||
link edit.
|
||||
- dependencyEdits: exact new contents of every manifest — both
|
||||
email-processor requirements.txt (handbook empty-with-comment), wo/web_ui
|
||||
(empty-with-comment), po/web_ui + po/site_extractor (NEW; decide pinned dep
|
||||
vs whether the dependabot entry is worthwhile — a dependabot entry needs at
|
||||
least one pinned dep to act on, so pin boto3 exactly if you want the entry
|
||||
live), tests/ (moto==<resolved version> from recon) — plus the exact
|
||||
dependabot.yml additions (three entries) matching the existing shape.
|
||||
- bundlingEdits: both email-processor bundling command strings BEFORE and
|
||||
AFTER, verbatim — the cp-only result, an explicit proof line that no
|
||||
third-party dep remains (so removing the whole pip step is safe, NOT a
|

regression of the manylinux pin), and confirmation the exclude lists +
|
||||
widened '../lambdas' root + any Phase-3 'cp shared/*.py' line survive
|
||||
untouched. If Phase 4 moved bundling into a helper, target that location.
|
||||
- packageCleanup: the exact rm -rf command for
|
||||
lambdas/po/email_processor/package/, the note that it is a filesystem rm
|
||||
(UNTRACKED — never git rm) performed and REPORTED by the Package agent, not
|
||||
committed, and why it is asset-hash-neutral (Phase 2 exclude).
|

- verifyRules: exactly how Verify judges success — the pytest set incl. the
|
||||
new contract test, ruff now INCLUDING scripts/, both cdk synth,

dependabot.yml yaml-parse, requirements resolve/import, and the runtime

some code path need a newer boto3 than the runtime ships? (3) Are the Phase

**Deterministic template parser.** `template_parser.try_deterministic_parse()` classifies by exact subject regex, extracts the nested contract (`supplier{}`, `ship_to{}` — 8 keys, `line_items[]` — 10 keys per item), and returns a parsed result **only if** it passes a fail-closed validation gate: recursive exact key-set at every nesting level; `email_type` emitted **only** on the exact new-PO subject *and* a confirmed-safe `Status` (never defaulted — a cancellation misrouted as `new_po` would defeat the sticky-`Cancelled` guard); `po_number` shape + byte-equality with the subject, the body `PO ID`, the `Amazon Purchase Order #` heading, and the `orders/<id>` URL; duplicate-label anchor integrity (`Supplier`/`Shipping`/`Total` each appear twice, the first `Shipping` must be the literal `None` placeholder); money fidelity (every `Decimal` re-serializes byte-identically to its source token with a digit/comma border check — the thousands-separator-truncation kill switch — plus `sum(line amounts) == total`, proven against **both** `Total` blocks); bullet-metadata label discipline (closed label set, assigned by leading label, never ordinal — immune to the optional `Part Number` segment); USPS address shape on the raw pre-enrichment value; and rejection of any unparseable sentinel or residual `\r`/`\xa0` artifact. Multi-line-item (0.18%) and non-USD (0 observed) new-POs, comment emails, and anything else falls back to the AI extractor. The AI path is gated too: the untrusted email reaches Bedrock inside a neutralized `<email>` data block (forged tag lookalikes in the body are defanged) with `temperature=0`, and the raw model output must pass the fail-closed `validate_ai_fallback()` gate — the PO-specific nested contract (exact key-set at every level, with missing keys normalized rather than rejected), a `po_number` shape check hardened against fullwidth-digit and trailing-artifact injection (the same regex family protecting the DynamoDB partition key the handler builds from it), an `email_type` allow-list enforced *before* dispatch so a miss can never fall into the `new_po` default branch, and `Decimal`/`int`/`None` money typing (PO decodes with `parse_float=Decimal`) — before any DynamoDB write. **The template path is gate-enforced end-to-end; the AI-fallback path is validated and fail-closed — output that fails the gate is skipped, never written (see `ai_fallback_rejected` below), so a malformed or injected email raises the fallback rate rather than corrupting a record.** Every record emits one CloudWatch EMF metric (see below).
|
||||
|
||||
**Derived fields (`site_code`, `trade`, `fiscal_year`).** These three are **classified**, not verbatim-extracted, so neither parse path emits them directly — instead a deterministic Python classifier (`derived_fields.derive_all()`) computes them inside the shared `enrich_parsed()` post-stage, which runs identically on both paths. `trade` is a closed label set (the same one the AI prompt enumerates): `Plumbing - PM`, `Plumbing - Reactive`, `Electrical`, `HVAC`, `Dock Doors`, `Doors`, `Signage`, `Carpentry`, `Fencing/Gates`, `Conveyance/MHE`, `Painting`, `Flooring`, `Janitorial`, `Fire/Life Safety`, `Landscaping/Yard`, `Roofing`, `Security/Locksmith`, `Snow Removal`, `PO Uplift`, `General Building - Emergency`, `General Building - Handyman`, `General Building - Project`, `General Building`.

The docstring reword is deferred to the first post-bake PR, since even a text-only edit is barred by this phase's machine-checked empty-diff gate on the file. `trade` is a closed label set (the same one the AI prompt enumerates): `Plumbing - PM`, `Plumbing - Reactive`, `Electrical`, `HVAC`, `Dock Doors`, `Doors`, `Signage`, `Carpentry`, `Fencing/Gates`, `Conveyance/MHE`, `Painting`, `Flooring`, `Janitorial`, `Fire/Life Safety`, `Landscaping/Yard`, `Roofing`, `Security/Locksmith`, `Snow Removal`, `PO Uplift`, `General Building - Emergency`, `General Building - Handyman`, `General Building - Project`, `General Building`. Authority differs by path:
|

- **Template path** — the parser leaves all three `null`, so Python is authoritative: it fills them.
|

- **AI-fallback path** — the LLM value stays **authoritative during the bake** (Python fills only a gap the LLM left `null`, never overwrites), and Python additionally runs in **shadow mode**: `enrich_parsed()` emits one `DerivedFieldAgreement` EMF record per field comparing the two.

**IaC:** AWS CDK (Python), two stacks in one app, region `us-east-1`. The `cdk.Environment` is deliberately **account-agnostic** (region-only, no `account=`): the stacks deploy to whichever account the deploy credentials target (`328440206208` today), and every account-derived template value — bucket names, `Lambda::Permission` source account, the site-alerts SNS action ARN, the Bedrock ARN below — renders as the CloudFormation `AWS::AccountId` pseudo-parameter rather than a literal. Pinning `account=` was evaluated in Phase 4 and rejected: it would resolve those tokens to literals, and against the deployed (account-agnostic) templates CloudFormation flags the `RemovalPolicy.RETAIN` email buckets as requiring replacement — a data-loss risk — for no functional gain.

|
||||
|
||||
### Shared CDK helpers (`cdk/common.py`, Phase 4)
|
||||
|
||||
The ~379 lines that `po_stack.py` and `wo_stack.py` both defined identically (DynamoDB alarms, the sender-auth-rejected metric filter + alarm, the standard per-Lambda alarm set, the Bedrock `InvokeModel` grant, the raw-email bucket, the async-invoke DLQ, and the template-fallback-rate math alarm) are collapsed into `cdk/common.py`.
|
||||
|
||||
**Logical-ID-safety rule (load-bearing).** Every helper is a **plain function** taking `(scope, id, ...)` — never a `Construct` subclass. Each stack calls a helper with its **own Stack instance as `scope`** and the **exact same literal construct id** it used inline before the extraction, so every synthesized logical ID is byte-stable. A `Construct` subclass would insert an extra tree node, reparent every child's logical ID, and CloudFormation would attempt to **replace** the `RemovalPolicy.RETAIN`-protected `purchase-orders` / `WorkOrders` / `WorkOrderComments` tables and the named S3 buckets — a data-loss event. Nothing in `common.py` subclasses `Construct`, and it imports only the CDK constructs its helpers touch (`dynamodb`, `cloudwatch`/`cw_actions`, `iam`, `logs`, `s3`, `sqs` — no `kms`, `ssm`, or Lambda event-source imports).
|
||||
|
||||
Extracted helpers: `add_ddb_alarms`, `add_sender_auth_rejected_alarm`, `add_standard_lambda_alarms` (bespoke `descriptions=` dict passed through verbatim per call site — no alarm text is generated or homogenized), `make_bedrock_invoke_statement`, `make_email_bucket`, `make_processor_dlq`, `make_fallback_rate_alarm`. Per-function alarm variance is preserved exactly through call-site arguments, not baked into the helpers: PO's email-processor duration alarm uses `p99`, WO's uses `p95`; `po-web-ui` gets throttles + duration only (no errors, no DLQ); `po-ingest-site-extractor` has no DLQ alarm (it's a DynamoDB-stream consumer, not async-invoked); `workorder-web-ui` gets **zero** alarms — the helper is simply never called for it, so it cannot silently add any. The two "AI-fallback-rejected" alarms (PO's 6-hour count-floor `IF(FILL(rej,0)>=1,...)`, WO's 5-minute/2-of-6 sparse idiom) are a different shape from `make_fallback_rate_alarm` and stay as distinct inline call sites in each stack rather than being forced through the shared helper.
|
||||
|
||||
**Bedrock ARN, now account/region-derived.** `make_bedrock_invoke_statement(scope)` builds the inference-profile ARN and the `us-east-1` foundation-model ARN from `Stack.of(scope).account` / `.region` instead of the previous hardcoded `328440206208`/`us-east-1` literals (the `us-east-2`/`us-west-2` foundation-model ARNs stay literal — they're fixed cross-region reach targets, not the stack's own region). Because the environment is account-agnostic (above), `stack.account` is the `AWS::AccountId` pseudo-parameter, so the derived ARN synthesizes as an `Fn::Sub`/`Ref` that **resolves at deploy time to the same ARN** the hardcoded literal named in-account. Versus the deployed stack this is a benign **in-place** IAM policy update (IAM policies never require replacement) — and it makes the grant account-portable instead of pinned to the management account. This IAM PolicyStatement change is the surface the mandatory GPT-4.1 cross-family review covers.
|
||||
|
||||
**New `CfnOutput`s.** Each stack now exports its Lambda function ARNs and the DynamoDB table names it owns/consumes, all net-new/additive (no existing output changes): `po-ingest` — `EmailProcessorFunctionArn`, `WebUiFunctionArn`, `SiteExtractorFunctionArn`, `PurchaseOrdersTableName`, `PendingSiteReviewTableName` (the existing `VerifiedSitesTableName` output is unchanged); `workorder-ingest` — `EmailProcessorFunctionArn`, `WebUiFunctionArn`, `WorkOrdersTableName`, `WorkOrderCommentsTableName`.

|
||||
The `From` header and any `Authentication-Results` header inside the raw MIME are attacker-forgeable, so neither is trusted. Instead, both email processors authenticate the sender against the verdicts SES itself stamps at delivery time, failing closed. The authenticator is **single-sourced** at `lambdas/shared/ses_auth.py` (Phase 3) — previously duplicated byte-for-byte in each pipeline's `email_processor/` dir and kept in sync by a fixture-hygiene test; now one copy, so a future hardening fix to the fail-closed logic lands **once** instead of needing two identical edits. The CDK bundling `cp`s it flat beside each handler so the handlers' unchanged `from ses_auth import authenticate_inbound_email` still resolves at runtime (see [`lambdas/shared/`](#deploy-pipeline-guards-phase-0)). The gate:
|
||||
|
||||
1. Take **only the topmost** `Authentication-Results` header (SES prepends its trace headers; any lower copies arrived inside the message and are ignored).
|
||||
2. Require its authserv-id to be `amazonses.com`.

**Parse-outcome metric + fallback-rate alarm (workorder-ingest):** the WO processor writes one CloudWatch **EMF** line per email to namespace `Seahaven/WorkorderIngest`, metric `ParseOutcome` (Unit Count, value 1), dimensioned by `ParseMethod` (`template` | `ai_fallback` | `ai_fallback_rejected`) and `TemplateId` (`update_plaintext` | `assign_html` | `unknown`). `ai_fallback_rejected` counts AI-fallback output that failed the fail-closed `validate_ai_fallback()` gate (schema/enum/date contract on raw Bedrock output — prompt-injection defence) and was dropped without a DynamoDB write. Non-dimension EMF properties `ReasonCode` and `work_order_id` are queryable in Logs Insights but not promoted to metrics (kept low-cardinality). EMF is used instead of `PutMetricData` so there is no extra sync call / latency / IAM grant on the async hot path (the role already has `logs:PutLogEvents`). The alarm `workorder-email-processor-template-fallback-rate` fires when the AI-fallback share of parses — rejected fallback parses included, so a drift outage whose AI output also fails the gate cannot lower the observed rate while dropping mail — exceeds **15%** sustained (a `MathExpression` with `FILL(...,0)` and a ≥10-sample volume floor over 15-minute periods, eval 3 / datapoints 2) — catching Hexagon template-drift coverage collapse while the volume floor + `FILL` prevent low-volume false pages / `INSUFFICIENT_DATA`. ALARM-only `SnsAction` to `site-alerts`, no OK action, `NOT_BREACHING`. The 15-minute period is a deliberate deviation from the 5-minute house style to accumulate a stable denominator at the low ~760/day volume. A second alarm, `workorder-email-processor-ai-fallback-rejected`, pages on the rejected series itself (≥1 rejection per 5-min period, 2 of the last 6 periods — the sender-auth-rejected sparse-arrival idiom) because a gate rejection drops mail without error/retry/DLQ and would otherwise be silent.
|
||||
|
||||
**Parse-outcome metric + fallback-rate alarm (po-ingest):** the PO processor emits the same EMF shape to namespace `Seahaven/PoIngest`, metric `ParseOutcome`, dimensioned by `ParseMethod` (`template` | `ai_fallback` | `ai_fallback_rejected`) and `TemplateId` (`coupa_new_po` | `coupa_cancellation` | `unknown`), with `ReasonCode` (the fail-closed gate reason) and `po_number` as Logs-Insights ride-alongs. `ai_fallback_rejected` counts AI-fallback output that failed the fail-closed `validate_ai_fallback()` gate (nested key-set contract, `po_number` shape, `email_type` allow-list, `Decimal` money typing) and was dropped without a DynamoDB write.
|
||||
**WO Bedrock transport-error metric (Phase 8).** A Bedrock-side transport error (throttling, malformed response, non-JSON model text) during the AI-fallback attempt previously emitted **zero** `ParseOutcome` datapoints — the only emit sites were post-gate. `handler.py` now wraps the `extract_with_bedrock` call in a try/except that emits exactly one `ParseMethod=ai_fallback` / `ReasonCode=bedrock_error` datapoint and then re-raises (the exception still propagates into the errors alarm / DLQ path unchanged). This is an except-and-reraise, not a reorder: a gate-rejected email (Bedrock *returns* successfully, `validate_ai_fallback()` then rejects it) still emits only the single `ai_fallback_rejected` datapoint and nothing else — the except branch never fires because Bedrock did not raise — so the `workorder-email-processor-ai-fallback-rejected` "a rejected email emits nothing else" alarm contract holds with no double-count.

||||
**Parse-outcome metric + fallback-rate alarm (po-ingest):** the PO processor emits the same EMF shape to namespace `Seahaven/PoIngest`, metric `ParseOutcome`, dimensioned by `ParseMethod` (`template` | `ai_fallback` | `ai_fallback_rejected`) and `TemplateId` (`coupa_new_po` | `coupa_cancellation` | `unknown`), with `ReasonCode` (the fail-closed gate reason) and `po_number` as Logs-Insights ride-alongs. `ai_fallback_rejected` counts AI-fallback output that failed the fail-closed `validate_ai_fallback()` gate (nested key-set contract, `po_number` shape, `email_type` allow-list, `Decimal` money typing) and was dropped without a DynamoDB write. The `ai_fallback_rejected` emission's `po_number` ride-along is clamped to 64 chars (`handler.py:118`, pinned by the PO-DC-02 regression test) — `telemetry.py`'s `DerivedFieldAgreement` `PythonValue`/`LlmValue` properties clamp the same way.
|
||||
|
||||
**Deliberate double-count:** unlike WO, PO emits `ParseMethod=ai_fallback` *before* the Bedrock call (so a Bedrock-side error still records the outcome) — a rejected email therefore always emits **both** an `ai_fallback` datapoint (pre-call) and an `ai_fallback_rejected` datapoint (post-gate), never just the latter. This is intentional and load-bearing, not a bug; the fallback-rate math below treats `fb` as already inclusive of every rejection.

`tests/test_bundle_consistency.py` guards all of the above with a pure-AST check (no synth, no boto3, no handler import): it parses each handler.py's top-level first-party sibling imports, extracts the bundling `command=[...]` string from the corresponding CDK stack file, and asserts every required sibling module is guaranteed to ship. It recognizes both the scoped glob (`cp po/email_processor/*.py` / `cp wo/email_processor/*.py`, with or without a path prefix) and a whole-dir recursive copy (`cp -r . /asset-output/`) as unconditionally-safe shapes, and falls back to literal filename matching for any other (allowlist-style) shape. It pins each stack's command to the scoped-glob form specifically — a future revert to a narrowed single-file copy, a commented-out glob, or a filename allowlist missing a sibling all fail CI loudly instead of silently shipping a broken bundle. Runs in the existing pytest step, before synth.
|
||||
|
||||
### Phase 3: shared module extraction (`lambdas/shared/`)
|
||||
|
||||
Four first-party modules that were previously duplicated per pipeline (or inlined in each handler) are now **single-sourced** under `lambdas/shared/`, following the handbook's `lambdas/shared/` convention:
|
||||
|
||||
| Module | What it is | Imported by |
|
||||
|---|---|---|
|
||||
| `ses_auth.py` | fail-closed SES sender-authentication (INFRA-107) | both email processors |
|
||||
| `web_ui_auth.py` | fail-closed `X-Auth-Token` gate + token cache (INFRA-74) | both web_ui handlers |
|
||||
| `email_parsing.py` | `parse_raw_email` (the WO superset that returns `cc` unconditionally; PO simply ignores `cc`) | both email processors |
|
||||
| `emf.py` | generic CloudWatch EMF emitter (`emit_metric`, `emit_parse_outcome`) parameterized by namespace / dimension-sets / properties | both email processors (PO also uses `emit_metric` for `DerivedFieldAgreement`) |
|
||||
|
||||
**Flat-landing import rule.** The shared dir has **no `__init__.py`** — the modules are consumed by bare name (`from ses_auth import ...`, `from emf import emit_parse_outcome`), exactly as when they were siblings. This works because the bundling `cp` lands them **flat in `/asset-output/`** beside `handler.py`, so at runtime each shared module sits on the function's own `sys.path` under its bare name — the handler import lines are unchanged, which is what keeps the byte-identical fail-closed `ses_auth` behavior through the move. The load-bearing `emf` dimension-set list `[["ParseMethod"], ["ParseMethod", "TemplateId"]]` is now pinned **once** in `emf.py` (one-sided dimension drift between the two pipelines becomes structurally impossible), while the deliberate per-pipeline **emission-ordering** differences stay in the handlers (PO emits `ai_fallback` *before* the Bedrock call with an intentional double-count; WO emits mutually-exclusive `ai_fallback`/`ai_fallback_rejected` after its gate).
|
||||
|
||||
**Bundling — email processors.** Both email-processor commands append a second glob, `cp shared/*.py /asset-output/`, after their own `cp <pipeline>/email_processor/*.py`. This ships all four shared modules flat into each email-processor zip. `web_ui_auth.py` therefore rides along into both email-processor bundles even though the email handlers never import it — a harmless, deliberate consequence of the all-of-`shared/` glob (`PO_EXPECTED_TOP_LEVEL_MODULES` and the bundle-parity expectations account for it). The base is cp-only (Phase 7 removed the pip install / `manylinux` pin from both email-processor commands, and this phase moves only pure first-party modules with no new dependencies, so it **stays** cp-only — no pip step is reintroduced).
|
||||
|
||||
**Bundling — web UIs.** Both `po-web-ui` and `workorder-web-ui` gain the same widened-root Docker bundling mechanism: their `Code.from_asset` root widens to `../lambdas` and their command copies the function's own dir contents plus **only** `shared/web_ui_auth.py` (`cp shared/web_ui_auth.py`, *not* `cp shared/*.py`) — the web UIs need only the auth module, and shipping the email-processor-only modules would break the "deployed set + `web_ui_auth`, nothing else" parity. The per-stack INFRA-74 comments stay in each handler (their wording is deliberately pipeline-specific and is not unified). `site_extractor`'s asset is untouched.
|
||||
|
||||
`tests/test_bundle_consistency.py` is updated in lockstep without losing teeth: `_first_party_sibling_imports` resolves shared-sourced imports under `lambdas/shared/`; the command extractor selects the email-processor command now that each stack has two bundled functions; `_bundling_ships_all` accumulates shipped module stems across **both** globs; `PO_EXPECTED_TOP_LEVEL_MODULES` gains the four shared modules; and a new pin + mutation test require the `cp shared/*.py` line to be actually executed (a commented-out or removed shared `cp` fails CI).
|
||||
|
||||
### Phase 5: handler decomposition + lazy boto3 clients
|
||||
|
||||
Both email-processor God-handlers are decomposed along the seams that already work into **flat sibling modules** in the same directory (bare-name imports, exactly like the `ses_auth`/`template_parser`/`derived_fields` pattern), so the Phase 0/2/3 `cp <pipeline>/email_processor/*.py` glob ships every new sibling automatically — no bundling change beyond the exact-set pin. Every move is a pure delete-here/add-there; `derived_fields.py`, both `template_parser.py`, the `validate_ai_fallback` gates, `lambdas/shared/`, and `cdk/` are byte-untouched.
|
||||
|
||||
**PO** (`handler.py` → 5 siblings + `prompts.py`): `handler.py` keeps the event loop, fail-closed SES auth, and `email_type` routing; `extraction.py` owns `extract_with_claude` + `_EMAIL_TAG_RE`; `enrichment.py` owns `enrich_parsed` + `pad_zip` (PO-only — WO has no enrichment stage) as a byte-identical move including the derived-field shadow block; `telemetry.py` owns the EMF `ParseMethod`/`DerivedFieldAgreement` emit wrappers; `persistence.py` owns `_write_fields`/`_merge_update`/`save_*` — with the two byte-identical `save_new_po`/`save_revision` **collapsed into one `_save_merge`** plus two thin wrappers differing only in the log verb (behavior-identical to both originals, sticky-cancel `ConditionExpression` guard intact; `save_cancellation` stays its own function). **WO** splits into ~5 concerns (no `enrichment`), keeping `validate_ai_fallback` **and** the `re.fullmatch(r"[0-9]+", work_order_id)` key guard in the handler loop AHEAD of both `save_work_order` and `save_event` (it protects the partition key and the `#`-delimited `comment_id` range-key segment), and keeps `_header_date_iso`/`comment_id` determinism together with `save_event` in `persistence.py`.
|
||||
|
||||
`EXTRACTION_PROMPT` (the ~181-line prompt) moves to `prompts.py` with a cross-reference header to the second authoritative copy of the trade/site/fiscal rule tables in `derived_fields.py`; `handler.py` keeps a `from prompts import EXTRACTION_PROMPT` re-export so `handler.EXTRACTION_PROMPT` still resolves for the tests that dereference it.
|
||||
|
||||
**Lazy cached boto3 clients.** Each I/O module initializes its client cache to `None` and populates it through a private `_get_<client>()` accessor on first call (`extraction.bedrock`, `persistence.dynamodb`, `handler.s3`); pure modules (`enrichment`, `telemetry`, `prompts`) import no boto3. The cache attribute keeps its original public name, so a test patches the same attribute — only the owning **module** moved (e.g. `setattr(persistence, "dynamodb", fake)`). Building the client at first *call* (deep inside a test) rather than at import also strengthens the moto-before-handler invariant.
|
||||
|
||||
**Behavior preserved (pinned by new tests).** PO emits `ParseMethod=ai_fallback` **before** the Bedrock call (a throttle that raises still leaves the pre-call datapoint), and a gate rejection is an additive second `ai_fallback_rejected` datapoint (PO's deliberate double-count); WO emits **after** its gate, mutually exclusive; the `DerivedFieldAgreement` shadow telemetry stays `ai_fallback`-only; `_save_merge` issues byte-identical `update_item` calls for both `new_po` and `revision`; and the WO key guard fires before either save.
|
||||
|
||||
## Security
|
||||
|
||||
**Web UI auth (defense-in-depth).** The `po-web-ui` / `workorder-web-ui` handlers refuse unauthenticated requests even though their public Function URLs were removed (INFRA-74). Each requires a shared secret in the `X-Auth-Token` header (or `Authorization: Bearer <token>`), compared in constant time against the configured token. The handler **fails closed** if the token is unset or unreadable (denies all). The token lives in the Secrets Manager secret `procurement-ingest/web-ui-auth-token`; only its ARN is passed to the Lambda (`WEB_UI_AUTH_TOKEN_SECRET_ARN`), and the value is fetched at runtime — never embedded in the CloudFormation template or Lambda env vars. The fetched value is cached in the warm container with a short TTL (5 min) so a rotated secret propagates without waiting for the execution environment to recycle. This is a defense-in-depth floor for a detached URL, not primary auth.

|

**Consumer (read-only) — data contract:** `seahaven-slack-bot` imports both tables via `Table.fromTableName(...)` (`grantReadData`) and reads them from two Lambdas: `workorder-sync` (daily full-table scan into the Bedrock knowledge base) and `wo-po-lookup` (the Bedrock agent's direct WO lookup action group). The bot depends on the PK/SK schema above and these attributes: on `WorkOrders` — `description`, `wo_status`, `customer`, `site_code`, `building`, `address`, `severity`, `priority`, `assigned_to`, `date_reported`, `scheduled_start`, `due_date`, `updated_at`; on `WorkOrderComments` — `created_at` (used to sort comments), `commenter`, `text`. Any change to table name, key schema, these attribute names, or the encryption configuration (e.g. the INFRA-6 CMK migration) must be coordinated with `seahaven-slack-bot` before it ships, or the Bedrock agent breaks at runtime (not at deploy — the tables are imported by name, so there is no compile-time link).
|
||||
|
||||
**Stream field contract (`site_code`).** Three definitions of "is this a valid site code" have existed in this repo at once. The canonical shape is `derived_fields._STRICT_CODE_RE` (`[A-Z][A-Z0-9]{2,4}`, `fullmatch`) plus its skip-list semantics (a code-shaped token is only a real site code if it is *not* skip-listed, e.g. `LLC`/`INC`/`CORP`/`LTD`/`ATTN`), used by `derive_site_code()` (the `enrich_parsed()` classifier, see the **Derived fields** note in the Purchase Orders flow above). Honestly noted, not papered over: `lambdas/po/site_extractor/handler.py`'s own `SITE_CODE_PATTERN` (`[A-Z]{2,4}\d{1,2}`, prefix-anchored `.match`, digit-requiring) still diverges from the canonical shape as of this phase — it rejects valid all-letter codes like `KLAL` (which surface as permanent `pending-site-review` rows) and accepts overlong junk like `DLI6X`/`SNY55` that the canonical `fullmatch` would not. Reconciling `po-ingest-site-extractor`'s direct-field validation onto the canonical `derived_fields` shape is Phase 6 scope, tracked separately — this paragraph will be updated when it lands.

**Test-root consolidation (Phase 8).** Both test roots are kept (`tests/` for genuinely cross-pipeline suites, plus each pipeline's own `lambdas/*/email_processor/tests/`), but loading is now single-sourced. A new repo-root `conftest.py` — not `tests/conftest.py`, which is never an ancestor of the pipeline test roots and so cannot load for a standalone `pytest lambdas/po/email_processor/tests` run — sets the dummy AWS env, imports `moto` before any handler import (registers moto's botocore stubber hook so boto3 sessions created afterwards are stubbable), and exposes the one `load_lambda_module(pipeline, name)` loader (implemented in `tests/support/loader.py`) that every handler exec in the suite goes through, including its `sys.modules` save/restore dance for the per-pipeline duplicated bare names (`template_parser`, `persistence`, etc. — `derived_fields`/`prompts`/`telemetry`/`extraction`/`enrichment` too). `tests/support/` is a small shared package (`FakeTable`, `FakeDynamoResource`, `FakeS3`, `load_email`, `load_golden`) used by both pipelines' `_po_parser_support.py`/`_wo_parser_support.py` shims — `load_golden` decodes JSON money with `parse_float=Decimal` unconditionally (load-bearing for PO's exact-money goldens; proven safe for WO, whose 55 golden fixtures contain zero float-typed JSON numbers). `test_local.py` (a root-level manual script that imported a handler at collection time, bypassing the loader gate, and globbed a nonexistent `samples/` dir) is deleted — the golden suites cover its role.

|
||||
- `tests/` — shared handler + cross-pipeline tests: `parse_raw_email` (`test_parse_raw_email.py`), the fail-closed sender-authentication parser (`test_ses_auth.py`, INFRA-107), the Phase 0 CDK-bundling/handler-import AST consistency check (`test_bundle_consistency.py` — see [Deploy-Pipeline Guards](#deploy-pipeline-guards-phase-0)), the `scripts/reprocess.py` synthetic S3-event-shape contract (`test_reprocess_contract.py`, Phase 7), and, new in Phase 8: the handler-level SES-auth reject seam per pipeline (`test_handler_auth_seam.py` — no auth monkeypatch + an empty `ALLOWED_DKIM_DOMAINS` must yield zero Bedrock calls, zero writes, no raise), and both web_ui functions' first coverage — fail-closed auth (`test_web_ui_auth.py`) and the handlers themselves, including a 401-without-a-table-scan assertion and a hostile-field escaping regression lock (`test_web_ui_handlers.py`).

- `lambdas/wo/email_processor/tests/` — the deterministic WO parser suite: golden-file tests over 55 real scrubbed `.eml` fixtures (`test_parser.py`), fail-closed validation-gate rules and adversarial/injection cases (`test_validation_gate.py`), the issue #23 `comment_id` idempotency invariants (`test_comment_id.py`), the Bedrock-fallback dispatch/EMF-metric behavior with a mocked `invoke_model` (`test_bedrock_fallback.py`, which also carries the Phase 5 behavior pins — WO's mutually-exclusive emit and the `[0-9]+` key guard ahead of both saves), and the Phase 0 direct-invoke healthcheck contract (`test_healthcheck.py`). Golden JSON lives under `tests/fixtures/expected/`. New in Phase 8: `test_wo_bedrock_transport.py` (transport errors — throttle, missing `content`, empty content, non-JSON model text — plus the hand-computed no-double-count pin for the `handler.py` except-and-reraise metric wrap, and the multi-record failure-isolation pin) and `test_wo_merge.py` (a moto-backed mirror of `test_po_merge.py` against the `WorkOrders` table — null-status never clobbers `wo_status`, `created_at` immutable, `status`→`wo_status` mapping, `None` fields absent from `SET`, `record_type` only-when-present). After Phase 5 the suite patches accessors on the owning siblings (`extraction.bedrock`, `persistence.dynamodb`, `persistence.datetime`, `persistence.save_*`) rather than on `handler`.

New in Phase 8: `test_po_bedrock_transport.py` (the same four transport-error cases as WO, asserting the pre-call `ai_fallback` metric survives and no partial write occurs, plus the multi-record failure-isolation pin) and, moved here from `tests/`: `test_po_merge.py` (#97, moto-backed merge-write semantics) and `test_pad_zip.py` (zip-code padding). After Phase 5 the suite patches accessors/constants on the owning siblings (`po_extraction.bedrock`/`.BEDROCK_MODEL_ID`/`._EMAIL_TAG_RE`, `po_persistence.dynamodb`/`.PO_TABLE`, `po_enrichment.derive_all`/`.pad_zip`, `po_telemetry.DERIVED_METRIC_NAME`) rather than on `po_handler`; re-exported names it calls (`save_*`, `extract_with_claude`, `enrich_parsed`, `_emit_parse_method_metric`, `EXTRACTION_PROMPT`) stay on `po_handler`.
|
||||
|
||||
All three roots are discovered by `pytest.ini` (`testpaths`).
|
||||
|
||||
**Coverage floor (Phase 8).** `pytest.ini`'s `addopts` runs `pytest-cov` with an explicit `--cov` path per first-party package (`lambdas/po/email_processor`, `lambdas/wo/email_processor`, `lambdas/po/web_ui`, `lambdas/wo/web_ui`, `lambdas/po/site_extractor`, `lambdas/shared`) rather than relying on an `__init__.py` package marker — none of these dirs have one, and adding one would perturb the CDK bundling asset-hash fingerprint for zero runtime benefit; `pytest-cov`'s path form measures by source file regardless of package markers. `site_extractor` is deliberately included even though it measures 0% until Phase 6 lands — coverage honesty, not a silent skip. `.coveragerc` omits `*/tests/*` and `*/cdk.out/*` so the pipeline test dirs (which sit inside their own `--cov` path) don't dilute the number. `--cov-fail-under` is the new permanent CI floor (constraint 10 — never ratcheted down).
|
||||
|
||||
**Ruff C901/PLR floor (Phase 8).** `ruff.toml` adds `extend-select = ["C901", "PLR"]` with `max-complexity = 12`, making the tree's pre-existing `# noqa: PLR09xx` suppressions load-bearing instead of inert (no config previously enabled the rules they suppressed). `scripts/` is in the lint scope. Findings that could not be split or were out of this phase's file-ownership were resolved with a per-file `[lint.per-file-ignores]` entry carrying a written justification — most notably `derived_fields.py` (shadow-bake freeze: even an in-file `noqa` comment is a barred edit) and the other Phase 3/5/6/7 frozen modules (`enrichment.py`, WO `template_parser.py`, both `ses_auth.py`/`emf.py`, `site_extractor/handler.py`, `scripts/reprocess.py`). PO's `template_parser.py` — this phase's one in-scope split target — clears the ceiling by decomposing `extract_new_po` and `_validate_new_po_values` into per-rule helpers instead of an ignore.
|
||||
|
||||
## Scripts
|
||||
|
||||
**Reprocess emails** (re-invoke an email-processor with a synthetic S3 event). `reprocess.py` is now **pipeline-general**: `--pipeline po|wo` selects the function + raw-email bucket. **Targeted replay** (`--key` one object, `--prefix`, or `--since` a `LastModified` timestamp) is the default, preferred mode; the full-prefix sweep is demoted behind an explicit `--all`. Every mode is dry-run unless `--execute`. See the [DLQ recovery runbook](docs/runbook-dlq-recovery.md) for the targeted single-key re-invoke flow.

- **Canonical `quantity`/`price` type = Decimal (DynamoDB Number), converged in the shared `enrich_parsed`:** `EXTRACTION_PROMPT` declares both fields as JSON strings, so a prompt-obedient Bedrock response arrives as `str` where the template path emits `Decimal`. The shared post-stage coerces numeric strings (thousands-separator-safe) to `Decimal` so both paths write the same attribute type to the purchase-orders table stream; non-numeric strings are left verbatim. Prompt rewording itself stays PR #2 scope. The two-path parity test feeds a prompt-shaped payload (string quantity/price, LLM-filled `site_code`) — never the parser-derived golden verbatim — so it cannot be circular.

- **Canonical `quantity`/`price` type = Decimal (DynamoDB Number), converged in the shared `enrich_parsed`:** `EXTRACTION_PROMPT` declares both fields as JSON `"number or null"` (see the PR #2 prompt tweak above — `prompts.py:67-69`), not JSON strings; `parse_float=Decimal` already handles a conforming numeric response the same as the template path's `Decimal`. The shared post-stage's numeric-string-to-`Decimal` coercion (thousands-separator-safe) remains as a defensive net for a non-conforming model response that arrives as `str` anyway; non-numeric strings are left verbatim. `prompts.py` itself is frozen this phase — this is a doc-only correction. The two-path parity test feeds a prompt-shaped payload (string quantity/price, LLM-filled `site_code`) — never the parser-derived golden verbatim — so it cannot be circular.
|
||||
- **Second-pass header scrub (post-review):** the first-pass harvest scrub left the real SES `Feedback-ID` sender-identity hash on every Coupa fixture and, on the two non-Coupa fixtures, an embedded second SES block's `X-Ses-Receipt`, the Exchange cross-tenant UPN ciphertext, Gmail ARC `fh=` / `X-Gm-*` tokens, and related opaque routing blobs. All replaced with same-shape `ScrubbedFixture` placeholders (byte-safe, CRLF preserved); the fixture-hygiene test now asserts these token classes are scrubbed in every header block so regressions are caught.

||||
|
||||
## PO number
|
||||
|
||||
Extract from the email subject or body. Format is a prefix + hyphen + digits:
|
||||
- "2D-18206023", "FK-21088051", "B187-17955555"
|
||||
|
||||
## site_code extraction
|
||||
|
||||
The site code is the Amazon facility code — a 3-5 character alphanumeric code identifying
|
||||
the delivery site. Check these locations in order:
|
||||
|
||||
1. Ship-to name in parentheses: "Amazon.com Services LLC (KLAL)" → KLAL
|
||||
2. Ship-to name after dash: "Amazon.com Services LLC - SNY5" → SNY5
|
||||
3. Ship-to ATTN line with dash or en-dash: "ATTN: Wagon Wheel DS Station –WKY3" → WKY3
|
||||
4. Ship-to ATTN line directly: "Attn: HJX1" → HJX1
|
||||
5. Ship-to name IS the code: if the name is just "DBU2" or similar, use it
|
||||
6. Line item description prefix: "DYO1 - Sea Haven Ind - Plumbing Repairs" → DYO1
|
||||
7. Line item description in brackets: "[HMK4] Assemble 3 Wire Security Cages" → HMK4
|
||||
|
||||
**Not site codes — do not extract these as site_code:**
|
||||
- RME (Amazon Reliability Maintenance Engineering department)
|
||||
- BBM (Coupa description format tag)
|
||||
- JLL (Jones Lang LaSalle — facilities management vendor)
|
||||
- PARAG, ERIK (vendor/person names)
|
||||
- Industry acronyms: HVAC, LED, PVC, ADA, OSHA, EMR, BMS, DDC, MRO, NTE, EST
|
||||
|
||||
If the only candidate matches this skip list, set site_code to null.
|
||||
|
||||
## Ship-to address parsing
|
||||
|
||||
Parse the full address into separate fields. Be aware of these common issues:
|
||||
- State abbreviation may be missing entirely (e.g., "Tucson, 85704" with no state)
|
||||
- Zip codes may lack leading zeros (e.g., "MA 2149" should be zip "02149", "NJ 7001" should be "07001")
|
||||
- City names may be misspelled (e.g., "Charoltte" for Charlotte) — extract as-is, do not correct
|
||||
- Format varies: "City, ST - ZIP", "City, ST ZIP", "City, ZIP" (no state)
|
||||
|
||||
If state cannot be determined from the address, set ship_to.state to null.
|
||||
|
||||
## fiscal_year
|
||||
|
||||
The calendar year the work covers. Determine from:
|
||||
1. The order_date year (primary source)
|
||||
2. Need-by dates on line items
|
||||
3. Year in line item descriptions (e.g., "HVB2 - 2025 - Plumbing PM" → "2025")
|
||||
|
||||
Use the 4-digit year string (e.g., "2025").
|
||||
|
||||
## trade classification
|
||||
|
||||
Classify the primary trade from line item descriptions. Use the FIRST match in priority order:
|
||||
|
||||
**Plumbing - PM**: "plumbing pm", "plumbing preventative", "plumbing maintenance",
|
||||
or BBM format: "Plumbing - Backflow", "Plumbing - Water Heater - Install/Repair"
|
||||
|
||||
**Plumbing - Reactive**: "plumbing" with: "reactive", "emergency", "repair", "clog",
|
||||
"unclog", "leak", "flood", "sewer", "drain", "grease trap", "jetter", "water line",
|
||||
"toilet", "faucet", "urinal", "pipe"
|
||||
|
||||
**Electrical**: "electrical", "lighting", "ballast", "outlet", "circuit", "panel",
|
||||
"generator", "transformer", "conduit" (but NOT if "dock door" context)
|
||||
|
||||
**HVAC**: "hvac", "heating", "cooling", "air conditioning", "RTU", "AHU", "VAV",
|
||||
"refrigerant", "thermostat", "ductwork"
|
||||
|
||||
**Dock Doors**: "dock door", "dock leveler", "dock plate", "dock seal", "dock bumper"
|
||||
|
||||
**Doors**: "door", "overhead door", "roll-up", "automatic door", "access door"
|
||||
(only if not matched by Dock Doors above)
|
||||
|
||||
**Signage**: "sign", "banner", "wayfinding", "marquee", "directional"
|
||||
|
||||
**Carpentry**: "carpentry", "cabinet", "millwork", "trim", "shelving", "framing"
|
||||
|
||||
**Fencing/Gates**: "fence", "fencing", "gate", "bollard" (not "dock gate")
|
||||
|
||||
**Conveyance/MHE**: "conveyor", "MHE", "material handling", "sortation"
|
||||
|
||||
**Painting**: "paint", "painting", "primer", "coating", "touch-up"
|
||||
|
||||
**Flooring**: "floor", "tile", "carpet", "epoxy", "polishing"
|
||||
|
||||
**Janitorial**: "janitorial", "cleaning", "custodial", "pressure wash", "power wash"
|
||||
|
||||
**Fire/Life Safety**: "fire", "sprinkler", "extinguisher", "fire alarm", "suppression"
|
||||
|
||||
**Landscaping/Yard**: "landscape", "lawn", "tree", "yard", "mowing", "irrigation"
|
||||
|
||||
**Roofing**: "roof", "roofing", "gutter", "downspout"
|
||||
|
||||
**Security/Locksmith**: "lock", "key", "access control", "camera", "security", "CCTV"
|
||||
|
||||
**Snow Removal**: "snow", "ice", "salt", "de-ice", "plow"
|
||||
|
||||
**PO Uplift**: description is exactly or primarily "PO Uplift"
|
||||
|
||||
**General Building - Emergency**: "EMER" prefix, or "emergency" in a general building context
|
||||
|
||||
**General Building - Handyman**: BBM format "General Building - General Building Technician"
|
||||
|
||||
**General Building - Project**: BBM format "General Building - General Building Project"
|
||||
|
||||
**General Building**: any remaining facility maintenance work
|
||||
|
||||
If a PO has multiple line items with different trades, set "trade" to the primary
|
||||
(non-uplift, non-materials) trade. If genuinely mixed, use the trade of the highest-value line item.
|
||||
|
||||
## coupa_category
|
||||
|
||||
The Coupa commodity/category field if present in the email (e.g., "Maintenance - Facilities",
|
||||
"Plumbing Equipment & Materials"). This is Coupa's own classification, not the trade field.
|
||||
|
||||
## General rules
|
||||
|
||||
- Extract all line items with descriptions, amounts, and metadata
|
||||
- "quantity", "unit" (e.g., "EACH", "HR"), and "price" (unit price) should be extracted when present
|
||||
- total_amount should be the numeric total in USD
|
||||
- If a field is not present in the email, set it to null
|
||||
- Do NOT invent or infer data that is not explicitly in the email

## email_type detection
|
||||
|
||||
- "new_po": email announces a new purchase order being issued
|
||||
- "revision": email announces a revised/updated purchase order (look for "revised" in subject or body)
|
||||
- "cancellation": email announces a PO has been cancelled
|
||||
|
||||
## PO number
|
||||
|
||||
Extract from the email subject or body. Format is a prefix + hyphen + digits:
|
||||
- "2D-18206023", "FK-21088051", "B187-17955555"
|
||||
|
||||
## site_code extraction
|
||||
|
||||
The site code is the Amazon facility code — a 3-5 character alphanumeric code identifying
|
||||
the delivery site. Check these locations in order:
|
||||
|
||||
1. Ship-to name in parentheses: "Amazon.com Services LLC (KLAL)" → KLAL
|
||||
2. Ship-to name after dash: "Amazon.com Services LLC - SNY5" → SNY5
|
||||
3. Ship-to ATTN line with dash or en-dash: "ATTN: Wagon Wheel DS Station –WKY3" → WKY3
|
||||
4. Ship-to ATTN line directly: "Attn: HJX1" → HJX1
|
||||
5. Ship-to name IS the code: if the name is just "DBU2" or similar, use it
|
||||
6. Line item description prefix: "DYO1 - Sea Haven Ind - Plumbing Repairs" → DYO1
|
||||
7. Line item description in brackets: "[HMK4] Assemble 3 Wire Security Cages" → HMK4
|
||||
|
||||
**Not site codes — do not extract these as site_code:**
|
||||
- RME (Amazon Reliability Maintenance Engineering department)
|
||||
- BBM (Coupa description format tag)
|
||||
- JLL (Jones Lang LaSalle — facilities management vendor)
|
||||
- PARAG, ERIK (vendor/person names)
|
||||
- Industry acronyms: HVAC, LED, PVC, ADA, OSHA, EMR, BMS, DDC, MRO, NTE, EST
|
||||
|
||||
If the only candidate matches this skip list, set site_code to null.
|
||||
|
||||
## Ship-to address parsing
|
||||
|
||||
Parse the full address into separate fields. Be aware of these common issues:
|
||||
- State abbreviation may be missing entirely (e.g., "Tucson, 85704" with no state)
|
||||
- Zip codes may lack leading zeros (e.g., "MA 2149" should be zip "02149", "NJ 7001" should be "07001")
|
||||
- City names may be misspelled (e.g., "Charoltte" for Charlotte) — extract as-is, do not correct
|
||||
- Format varies: "City, ST - ZIP", "City, ST ZIP", "City, ZIP" (no state)
|
||||
|
||||
If state cannot be determined from the address, set ship_to.state to null.
|
||||
|
||||
## fiscal_year
|
||||
|
||||
The calendar year the work covers. Determine from:
|
||||
1. The order_date year (primary source)
|
||||
2. Need-by dates on line items
|
||||
3. Year in line item descriptions (e.g., "HVB2 - 2025 - Plumbing PM" → "2025")
|
||||
|
||||
Use the 4-digit year string (e.g., "2025").
|
||||
|
||||
## trade classification
|
||||
|
||||
Classify the primary trade from line item descriptions. Use the FIRST match in priority order:
|
||||
|
||||
**Plumbing - PM**: "plumbing pm", "plumbing preventative", "plumbing maintenance",
|
||||
or BBM format: "Plumbing - Backflow", "Plumbing - Water Heater - Install/Repair"
|
||||
|
||||
**Plumbing - Reactive**: "plumbing" with: "reactive", "emergency", "repair", "clog",
|
||||
"unclog", "leak", "flood", "sewer", "drain", "grease trap", "jetter", "water line",
|
||||
"toilet", "faucet", "urinal", "pipe"
|
||||
|
||||
**Electrical**: "electrical", "lighting", "ballast", "outlet", "circuit", "panel",
|
||||
"generator", "transformer", "conduit" (but NOT if "dock door" context)
|

"""Fail-closed SES sender authentication (INFRA-107).
|
||||
|
||||
SES Email Receiving *prepends* its own trace headers -- including an
|
||||
``Authentication-Results`` header whose authserv-id is ``amazonses.com`` --
|
||||
to the top of the raw MIME it writes to S3. Everything below those
|
||||
prepended headers (the From header, any additional Authentication-Results
|
||||
copies) is attacker-controlled, so ONLY the topmost Authentication-Results
|
||||
header is trusted, and only when its authserv-id is ``amazonses.com``.
|
||||
|
||||
An email is accepted only when that header carries ``dkim=pass`` for a
|
||||
domain in the ``ALLOWED_DKIM_DOMAINS`` allowlist (a comma-separated Lambda
|
||||
environment variable set by the CDK stack). Every other outcome fails
|
||||
closed and the email is rejected:
|
||||
|
||||
- ``ALLOWED_DKIM_DOMAINS`` unset or empty
|
||||
- no Authentication-Results header at all
|
||||
- topmost header unparseable or from an authserv-id other than SES
|
||||
- no ``dkim=pass`` clause
|
||||
- ``dkim=pass`` only for domains outside the allowlist
|
||||
|
||||
Observed SES format (2026-07-15, both ingest buckets)::
|
||||
|
||||
Authentication-Results: amazonses.com;
|
||||
spf=pass (spfCheck: ...) client-ip=...; envelope-from=...; helo=...;
|
||||
dkim=pass header.i=@seahaven.com;
|
||||
dmarc=none header.from=hxgnsmartcloud.com;
|
||||
|
||||
Note SES reports the passing DKIM identity as ``header.i=@<domain>``
|
||||
(RFC 6376 AUID), not ``header.d=``; the parser accepts both, and treats
|
||||
``header.d`` (the plain signing domain) as authoritative over ``header.i``
|
||||
when both are present. The ``header.i`` domain is derived per RFC 6376 as
|
||||
the part after the AUID's *last* ``@`` -- a ``@`` inside a quoted
|
||||
local-part (e.g. ``i="@seahaven.com"@attacker.com``) is signer-controlled
|
||||
label text, never the identity domain, and yields the true signer
|
||||
(``attacker.com``).
|
||||
|
||||
**Clause injection defence (INFRA-107 hardening).** SES echoes several
|
||||
attacker-controlled SMTP-session tokens into its own Authentication-Results
|
||||
value as their own semicolon-delimited property clauses -- notably
|
||||
``envelope-from=<MAIL FROM>``, ``helo=<HELO>`` and ``header.from=<From
|
||||
domain>``. An RFC 5321 quoted-local-part MAIL FROM may legally contain
|
||||
spaces and semicolons, e.g.::
|
||||
|
||||
MAIL FROM:<"x; dkim=pass header.i=@amazon.coupahost.com"@attacker.com>
|
||||
|
||||
which SES renders verbatim as ``envelope-from="x; dkim=pass
|
||||
header.i=@amazon.coupahost.com"@attacker.com;``. A naive ``split(";")``
|
||||
would tear the quoted string apart and manufacture a synthetic
|
||||
``dkim=pass header.i=@amazon.coupahost.com`` clause out of attacker input.
|
||||
The parser therefore tokenises per RFC 8601 / RFC 5322 structure: CFWS
|
||||
comments ``(...)`` are stripped first, and the value is split into clauses
|
||||
only on semicolons that sit *outside* a quoted-string. A ``;`` inside a
|
||||
quoted ``pvalue`` stays part of that one property clause and can never be
|
||||
read as the start of a ``dkim=`` methodspec.

Inspects only the `cp` commands bash actually executes (comments stripped

via `_executed_cp_commands`). An executed copy ships every top-level .py
|
||||
sibling unconditionally in two shapes:
|
||||
- a non-recursive glob copy whose (optional) path prefix resolves, under
|
||||
the ../lambdas bundling cwd, to a directory that ACTUALLY contains
|
||||
every required sibling, e.g. `cp po/email_processor/*.py /asset-output/`
|
||||
(PO, Phase 2). The directory is filesystem-checked, not merely
|
||||
pattern-matched: a wrong-pipeline or arbitrary-directory glob
|
||||
(`cp wo/email_processor/*.py` in po_stack, `cp venv/lib/*.py`) does NOT
|
||||
qualify, because that directory does not hold every required sibling --
|
||||
so it can never short-circuit to True while dropping a module;
|
||||
via `_executed_cp_commands`) and ACCUMULATES the set of shipped module
|
||||
stems across ALL of them -- because since Phase 3 the required siblings
|
||||
ship via TWO globs, not one: `cp <pipeline>/email_processor/*.py` covers
|
||||
the per-pipeline siblings and `cp shared/*.py` covers the single-sourced
|
||||
ones (ses_auth/email_parsing/emf). A single-cp "one glob ships everything"
|
||||
check would wrongly report False now that coverage is split.
|
||||
|
||||
Each executed cp contributes to the shipped set as follows:
|
||||
- a non-recursive `*.py` glob ships every top-level .py in the globbed
|
||||
directory -- but ONLY that directory. Its (optional) path prefix is
|
||||
resolved against the ../lambdas asset root (the Phase 2 bundling cwd)
|
||||
and every `.py` stem actually present there is added. A wrong-pipeline
|
||||
or arbitrary-directory glob (`cp wo/email_processor/*.py` in po_stack,
|
||||
`cp venv/lib/*.py`) therefore contributes only what that dir really
|
||||
holds (or nothing, if it does not exist) and can never cover a sibling
|
||||
that lives elsewhere;
|
||||
- a recursive copy of the WHOLE source dir, e.g. `cp -r . /asset-output/`
|
||||
-- the source operand must be `.`/`./`, so a narrowed recursive
|
||||
copy like `cp -r ./package /asset-output/` does NOT qualify.
|
||||
Any other executed `cp` is treated as an explicit filename allowlist (the
|
||||
legacy PO form) and is safe only if every required `<name>.py` literally
|
||||
appears among the copied filenames -- the branch that must reject a
|
||||
reverted allowlist missing a sibling.
|
||||
(`.`/`./` source only), ships everything -> short-circuit True;
|
||||
- any other executed `cp` is an explicit filename allowlist (the legacy
|

PO form): each copied `<name>.py` stem is added, so a reverted

allowlist missing a sibling leaves that sibling out of the set.
