* Fix payroll email: grant SES config-set permission + isolate failures
The weekly pay-summary email to payroll has been failing with SES
AccessDenied since 2026-06-08. The sending identity (seahaven.com) gained
a default configuration set (seahaven-email-events), and SES authorizes
SendEmail against the config-set ARN as well as the identity — but the
WeeklyPostFunction role only granted ses:SendEmail on identity/*.
- template.yaml: add the configuration-set ARN (scoped to the known set
name) to the SES policy so sends are authorized again.
- weekly-post/app.py: wrap _send_pay_email in try/except so a delivery
failure can never abort the handler before the Slack schedule post.
Previously the SES error also blocked the two-week schedule post.
- Add a regression test covering the isolation.
Cross-family GPT-4.1 IAM review: APPROVE.
* Bump to v1.10.1 in CHANGELOG and sync App Home copy
* 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.
* Fix shared layer packaging — remove python/ wrapper that caused double nesting
SAM BuildMethod: python3.12 wraps layer content in python/ during build.
The source had an extra python/ directory, resulting in the shared package
landing at python/python/shared/ instead of python/shared/. All 4 Lambdas
are failing with ImportModuleError since the PR #62 merge.
* Update CI source-dirs to match new shared layer path
* Add arm64, log retention, and compliance fixes
- Set arm64 architecture globally for all Lambda functions
- Add explicit CloudWatch log groups with 60-day retention
- Add missing WeeklyPostFunctionArn to stack outputs
- Add Dependabot assignees for both ecosystems
- Add samconfig.toml.example for onboarding
* Restructure src/ to per-function layout with shared Layer
Move from flat src/ to per-function directories:
- src/slack-bot/ — Slack Bolt Lambda handler
- src/weekly-post/ — Monday schedule + pay post
- src/roster-sync/ — Daily 3CX roster sync
- src/shared/ — Lambda Layer with schedule, blocks, three_cx_client
Each function has its own requirements.txt and CodeUri. Shared
modules are deployed as a SAM Layer (afterhours-shared) importable
as `from shared.X import Y`.
* Migrate secrets from SSM Parameter Store to Secrets Manager
- Slack bot token and signing secret now read from Secrets Manager
- 3CX credentials (domain, client-id, client-secret) moved to
Secrets Manager under afterhours-shift-manager/3cx-* prefix
- Channel ID is now a non-secret CloudFormation parameter (ShiftChannel)
- Add shared secrets.py helper for Secrets Manager reads
- Remove SSM and KMS IAM policies, add secretsmanager:GetSecretValue
* Merge ring-scheduler-3cx as 4th Lambda function
- Add afterhours-ring-scheduler Lambda with 4 EventBridge rules
(daily 8am EST/EDT + weekend 5pm EST/EDT) for 3CX ring group
routing updates
- Extract shared ring_scheduler.py module for direct ring group
updates from both the scheduled Lambda and the Slack bot
- Replace cross-Lambda invoke with direct update_ring_group() call
in the Slack bot — eliminates lambda:InvokeFunction dependency
- Use RingGroup API (correct) instead of Queue API (was wrong in
the original ring-scheduler repo)
- Eliminate YAML config fallback — DynamoDB is the sole schedule
source
- Add RingGroupNumber CloudFormation parameter
* Add schedule post live-update and old post deletion (#40, #41)
- Store schedule message timestamp in DynamoDB (SCHEDULE_POST record)
- Delete previous week's schedule post before posting the new one
- Live-update the schedule post via chat_update after any
pick/drop/swap/button-pickup so it always reflects current state
* Disallow past shifts and add day/night labels (#43, #42)
- Reject /oncall pick and /oncall drop for past dates
- Show ephemeral error when stale pickup buttons are clicked
- Hide pickup buttons for dates in the past
- Add explicit "Day (8am-5pm)" and "Night (5pm-8am)" labels to
schedule lines, pickup buttons, and shift change notifications
* Add admin slash commands for shift and roster management (#39)
- /oncall admin override <date> <ext> — assign a shift
- /oncall admin open <date> — mark shift as open
- /oncall admin clear <date> — remove override, revert to weekly
- /oncall admin roster add/remove/rename — manage roster entries
- Admin access gated by admin_users list in DynamoDB CONFIG
- Help message shows admin commands for admin users
* Update README for merged architecture and new features
* Switch from RingGroup API to Queue API at extension 801
The 3CX routing was changed from ring group 800 to queue 801 in a
previous PR on ring-scheduler-3cx. Updates all callers and the SAM
template parameter default accordingly.
* Pass SAM parameter overrides in deploy workflow
* Fix review findings: IAM, routing guards, past-date check, roster safety
- Ring scheduler: use DynamoDBCrudPolicy (resolve_shift needs Query)
- Button pickup: update 3CX for active shift type, not just night
- Pick/drop/swap commands: only update 3CX when shift type is active
- Swap command: add missing past-date guard
- add_roster_entry: reject if extension already exists
- Apply ruff formatting
* Add error handling to ring scheduler 3CX call
* Fix weekend day shift commands and admin 3CX routing
- Add _find_employee_shift() to check both day/night on weekends
- Drop/swap now correctly find and operate on weekend day shifts
- Pick finds first available shift type on weekends
- Admin override/open/clear update 3CX for same-day active shifts
* Fix dependabot directories and admin weekend shift handling
Dependabot now scans per-function requirement directories instead
of the repo root. Admin override/open/clear commands accept an
optional day/night parameter for weekend day shift management.
* Fix weekend day shift active window to 8am-5pm
Before midnight-8am on weekends incorrectly reported the day shift
as active when the previous night shift is still running.
* Show shift type label for both weekend shifts in notifications
Night shift notifications on weekends were missing the type label,
making them ambiguous. Also fix schedule post text fallback to use
this_monday instead of now for the start date.
* Extract determine_shift_type into shared layer
Eliminates duplicated weekend day/night boundary logic between
the ring scheduler and Slack bot Lambdas.
* Fix weekly schedule fallback start date

* Include weekend shift type in command confirmations
Co-authored-by: Adam Moussa <amoussa1229@users.noreply.github.com>
* Apply ruff formatting to app.py
* Only show day/night shift labels on weekends in schedule display
Weekday shifts are always night — the label was redundant clutter.
* Deduplicate 3CX forwarding payload and add shift type to pick command
Extract _update_forwarding helper in ThreeCXClient to share the
payload between queue and ring group methods. Add optional day/night
argument to /oncall pick so users can target a specific weekend shift.
* Consolidate WEEKEND_DAYS and fix weekday pickup button labels
Import WEEKEND_DAYS from shared.schedule instead of redefining in
blocks.py and weekly-post/app.py. Gate pickup button day/night
labels on weekends only, matching all other display surfaces.

Two root causes:
- claim_open_shift ConditionExpression failed when no OVERRIDE record
existed (shift available via weekly fallback). Added attribute_not_exists
check so claims succeed for both missing and OPEN overrides.
- Slack ack timeout: chat_postMessage took too long before respond() was
called, causing Slack to show an error. Moved respond() first and made
channel notifications best-effort with try/except.
Slash command handlers (drop, pick, swap) were posting notifications to
command["channel_id"] — wherever the command was run. If someone ran
/oncall drop from a DM, the notification went there instead of the
schedule channel. Pickup buttons didn't have this problem because
body["channel"]["id"] is always the channel where the button lives.
Added SHIFT_CHANNEL_PARAM to the SlackBotFunction env vars, read it on
cold start, and route all slash command shift-change notifications to
the configured schedule channel.
Closes#21
The pickup button handler used an unconditional put_item, so concurrent
clicks would both succeed with last-write-wins. Added claim_open_shift()
which uses a DynamoDB ConditionExpression to only write if the shift is
still OPEN. The button handler now returns an ephemeral "already taken"
message when the condition fails.
Closes#19
The handler passed `now` as start_date, so mid-week runs showed
14 days from today instead of Mon–Sun x2. Also, day names were
derived from a static index (DAY_ORDER[i%7]) which assumed
index 0 = Monday — when start_date wasn't Monday, Saturday and
Sunday were mislabeled as Monday and Tuesday.
Fix: pass this week's Monday from the handler, and derive day
names from the actual date via strftime instead of a static list.
Fixes#17
- Pay summary sent as DM to designated user instead of channel
- Email shows only per-person totals, no shift breakdown
- Renamed email subject/header to "Bonus Pay Summary"
