* feat(api): collapse Slack, portal, and jobs onto Fargate (PLAT-216)
Move HTTP and scheduled work onto one always-on Flask task so after-hours
loses Lambda cold start without changing the Cognito or roster contracts.
* fix(portal-api): keep CORS headers on unexpected 500s
Portal SPA error handling needs Access-Control-Allow-Origin even when
DynamoDB or other internals fail, otherwise the browser hides the 500.
* fix(api): retarget holidays per account and ship App Home changelog (PLAT-216)
* fix(iam): list ECS tasks and fail closed on non-prod Paychex (PLAT-216)
* fix(portal-api): serve portal JSON with an explicit JSON content type
Bolt parse_body raises JSONDecodeError for empty or non-JSON form
payload fields, which turned probe POSTs into unhandled Lambda 500s.
Fixes AFTERHOURS-SHIFT-MANAGER-2
* Add Slack admin modals + App Home admin section
Replace the two most error-prone positional admin commands with Block Kit
modals (override and holiday-add) opened from a new App Home admin section,
while keeping the typed subcommands as a fallback. Validation and side
effects are factored into shared helpers so the modal and command paths
can't drift, and every action/view handler re-checks is_admin against
get_admin_users() so a modal opened from Home can't bypass authorization.
Adds Schedule.list_overrides for the upcoming-overrides overview.

* Expand /oncall date parser to accept more formats
Users entering everyday forms like 7/3/26 hit a generic parse
failure because the parser only accepted four-digit years and a
bare m/d. Add two-digit-year and month-name (with optional
ordinal/year) formats, treating explicit-year inputs as fixed and
keeping the year-less roll-forward for bare m/d. Update the help
text and per-command parse hints to match.
Refs: #133
* Let drop pick a shift and flag night rows
Drop now accepts an optional [day|night|holiday] qualifier and, when a
date carries more than one shift the user holds, asks which to drop
instead of silently releasing the holiday or weekend day shift. The
static post also tags day/night rows with distinct glyphs and labels on
weekdays, so the after-hours row is unmistakable.
Refs: #134
* Refine night-row labeling and drop notifications
Weekday rows are night-only, so the moon glyph alone marks the
after-hours shift; the verbose time-range label is kept only on
weekend rows where day and night shifts coexist. Channel shift-change
notifications now label the shift on every day for parity. Thread the
caller's user_id through the regular-drop path instead of re-reading it
off the employee record, and document the user-facing changes.

* Add dash 4-digit year format and pin year boundary
Dash inputs like 7-3-2026 previously returned None because only the
slash variant had a 4-digit-year format. Add %m-%d-%Y so dash and slash
behave alike, and pin the two-digit-year century boundary with a test.

* Fix auth and race-condition flaws in shift commands
Four confirmed findings from the 2026-06-17 security sweep:
- register_user let any Slack user overwrite an extension already
bound to a different user (account takeover). Add a DynamoDB
ConditionExpression so a write only succeeds when the extension is
unclaimed or already this user's; raise ExtensionAlreadyRegistered
otherwise and surface a clear Slack message.
- The `rate` subcommand was routed without the is_admin flag, so any
user could set $0 pay rates. Gate _handle_rate on is_admin, matching
the admin-command guard.
- `/oncall pick` used a plain put_item (TOCTOU): two concurrent picks
both won. Use the atomic claim_open_shift conditional claim so the
loser gets an "already picked up" message.
- swap-accept overwrote a shift independently claimed after the swap
was initiated. Add reassign_if_held_by, a conditional write that only
applies the swap while the override is still the requester's (or on
the weekly fallback), and notify the accepter otherwise.
Add tests for the register-ownership guard and the rate admin guard.

* Scope shift-manager Lambda IAM to least privilege
The nightly sweep flagged four over-broad permissions. Scope each to
only what the function actually reads (verified against source):
- WeeklyPost: secrets to slack-bot-token-* only (was the whole
afterhours-shift-manager/* namespace); SES SendEmail to the single
noreply@seahaven.com identity (was identity/*).
- RosterSync and RingScheduler: secrets to 3cx-* only (was the whole
namespace); both read only the 3cx domain/client-id/client-secret.
SlackBotFunction and HolidayRouter wildcards are left unchanged — out
of scope for this sweep.
Refs: INFRA
* fix: re-validate shift holder on swap-accept (sh-security-review RIHB-1)
reassign_if_held_by trusted 'no override row' as 'still the requester's',
but a weekly-held shift also has no override row. An admin clear or weekly
edit between swap-init and accept could move the shift to a third party
with no override, letting the accept steal it (CWE-367, confirmed HIGH).
Re-resolve the current holder at accept and abort if it is no longer the
requester. Adds regression test + seeds the holder in existing accept tests.
* fix: complete IAM least-privilege sweep (sh-security-review)
HolidayRouter secrets scope afterhours-shift-manager/* -> /3cx-* (reads
only 3cx secrets); RingScheduler DynamoDBCrudPolicy -> DynamoDBReadPolicy
(read-only at runtime). SlackBot wildcard left as-is (reads across all
sub-prefixes; verified defensible).
Holiday day-shifts (08:00-17:00 ET) with N slots and 1.5x pay. A new
afterhours-holiday-router Lambda, fired by per-holiday EventBridge Scheduler
one-offs, repoints IVR 800 (key-0 + no-input/timeout) to holiday queue 802 and
sets 802's membership to the day's assignees (ext 100 fallback when unfilled),
reverting at 17:00. Pickups after a shift starts go through an admin Approve/Deny
flow for both regular and holiday shifts. Pay (weekly post + /oncall pay) shows
holiday rates distinctly.
Adds HOLIDAY and PICKUP_REQUEST DynamoDB record types, scheduler IAM scoped to
holiday-* schedules with conditioned PassRole, and the holiday-router function
with a 60-day log group and error alarm.
* Add changelog-driven releases and App Home tab
Version the bot continuously from CHANGELOG.md (the single source of
truth for both the version and the staff-readable notes) and surface
changes to users in two ways:
- A new afterhours-release-notifier Lambda posts a "What's New" message
to the shift channel on minor/major releases (patches stay silent).
- The bot gains an App Home "About" tab showing what it does, the
command list, and the current version's notes.
release.yaml runs on Deploy success (not release:published — GITHUB_TOKEN
events don't start downstream workflows), checks out the deployed commit,
and tags + publishes a GitHub Release + invokes the notifier. It assumes a
dedicated, boundary-carrying OIDC role scoped to InvokeFunction on the
notifier; the account's cfn role gates role creation on that boundary.
The manual Version Bump workflow is retired. A CI guard enforces that a
CHANGELOG edit is a clean SemVer bump and that the in-package copy matches.
* Harden release workflow and regex against CodeQL findings
Address three code-scanning alerts on the PR:
- Critical (actions/untrusted-checkout): split release.yaml into a
read-only `prepare` job that checks out and runs repo code, and a
privileged `publish` job (contents:write + OIDC) that never checks out
repo code — it tags, releases, and invokes purely through the GitHub
and AWS APIs. Also assert head_branch == main.
- High x2 (py/polynomial-redos): rewrite the italic and link regexes in
markdown_to_mrkdwn with possessive quantifiers and exclusive character
classes so they run in linear time on adversarial input. Adds a
regression test.
* Move release/announce into Deploy workflow to clear CodeQL
The workflow_run-triggered release.yaml kept tripping CodeQL's
privileged-context rules (untrusted-checkout, then cache-poisoning) —
CodeQL distrusts any workflow_run that checks out a ref, regardless of
the main-only guarantee, and there is no autofix.
Fold the release job into deploy.yaml gated on `needs: deploy`. A
push-to-main run is a trusted context, so checking out and running repo
code with write/OIDC is safe there. This still gates on deploy success
and serializes via the deploy concurrency group, and removes the
separate workflow entirely.
A user can no longer `/oncall drop` a shift inside the 24h window before it
starts — inside that window coverage must be handed off via a verified swap
(target accepts) or opened by an admin.
- app.py: _within_drop_lock(date, shift_type) (24h before _shift_start);
guard in _handle_drop after the ownership check. Admin `open` is a separate
handler and is unaffected (bypasses the lock).
- Removed the now-unreachable 3CX-repoint-on-drop branch: a same-day shift is
always inside the lock, so a drop never reaches mark_open for today.
- Help text + README note the 24h rule.
- tests: rewritten test_handle_drop (outside/inside-24h per shift type,
weekend day, admin bypass, plus the existing guard-precedence cases) and
direct _shift_start/_shift_started/_within_drop_lock helper tests. 185 passed.
Closes#84
/oncall swap no longer reassigns immediately. It now writes a pending SWAP
record and DMs the target Accept/Decline buttons; the shift only moves once
they accept.
- schedule.py: create_pending_swap / get_swap / mark_swap_verified /
clear_swap (PK=SWAP, date/shift SK mirroring OVERRIDE, status + timestamps
+ expires_at for TTL). A new request supersedes a prior pending one.
- app.py: _handle_swap creates the pending swap + DMs the target (requires the
target be Slack-linked; rejects self-swap). New module-level
handle_swap_accept / handle_swap_decline + two @app.action registrations.
Accept writes the override, repoints 3CX when it's the active shift, marks
the swap verified, notifies the channel + requester. Decline clears it and
DMs the requester. Lazy expiry: accept is rejected once the shift has started
(_shift_start/_shift_started).
- blocks.py: build_swap_request_blocks (Accept/Decline) + build_swap_resolved_blocks.
- template.yaml: enable DynamoDB TTL on expires_at so abandoned pending swaps
self-clean.
- tests: swap schedule methods, swap blocks, rewritten test_handle_swap
(pending + DM, no immediate override), new test_swap_accept_decline. 174 passed.
- README: swap behavior + SWAP item type + TTL.
The verified SWAP status is what #84 (24h drop guard) will query.
Closes#83
* Add pytest suite and wire it into CI
Stands up the first automated tests for the repo (151 tests) and turns on
the CI test step.
- Lift slack-bot handlers out of create_app() closures to module level so
they're unit-testable; create_app is now a thin Bolt-wiring layer. No
behavior change (handler entrypoints and create_app signature unchanged).
- tests/ mirrors src/: shared layer (schedule, blocks, 3CX client,
ring_scheduler, secrets) + all four Lambdas (pay math, drop/swap/pick/
admin/register/rate, pickup button, roster sync, queue scheduler).
- All boundaries mocked: DynamoDB/SES/Secrets via moto, 3CX HTTP via
responses, Slack via fakes, time via freezegun. No real network/AWS.
- pyproject.toml pytest config (pythonpath=src/shared, importlib mode);
per-package conftest loads each app.py under a unique name to avoid the
four-app.py collision. tests/requirements.txt for test-only deps.
- ci.yaml: run-tests: true (reusable workflow auto-installs deps) and lint
the tests dir too.
- README Testing section.
Closes#85
* Add least-privilege permissions block to CI workflow
Resolves the CodeQL actions/missing-workflow-permissions alert: the CI
workflow now restricts GITHUB_TOKEN to contents: read (it only checks out,
lints, and runs tests).
* Stop logging extension numbers in 3CX queue updates
Resolves 3 high CodeQL py/clear-text-logging-sensitive-data alerts: the
queue/ring-group forwarding logs no longer include the routed extension
values (closed/holiday/extension). Non-sensitive context (resource id,
queue number) is retained.
