The backend's new closing_date, the bid deadline, is a Closing column
before the start and end dates, which are now the contract's: the
details dialog calls them Contract start and Contract end. Closing
sorts soonest first, with no date last, and shows the time it closes
in the cell's tooltip and in the dialog. The API types are regenerated
for it.
To make room, the SME suitable column is now an SME badge beside the
status, shown only when it's suitable, so the Status column sorts by
status alone and a stored SME sort goes back to the default. The Mark
column is narrower. An opportunity without a status is shown as
Unknown, in the colours of the statuses without their own, such as
Cancelled and Withdrawn, rather than as a blank badge or a dash.
Find a Tender never sends tender.tenderPeriod.startDate, so an
opportunity's start date was always empty, and its end date was the
bid deadline. Start and end are now the contract period: from the
contracts' periods, else the awards' contract periods, else the lots'
contract periods, each date on its own, taking the earliest start and
the latest end of several.
The bid deadline (tenderPeriod.endDate) moves to a new closing_date
column (migration 00009), in the API as closing_date. EU Supply's
pages give no contract period, so its start and end are left empty
and its response deadline is the closing date.
internal/eusupply replaces the old Node scraper (eu-supply.js) for
uk.eu-supply.com. The site has no API, so it posts the public search
form, which now needs the form's current defaults and reads the HTML
with golang.org/x/net/html. Each tender not stored yet has its own
page read too, for its description, contract type, CPV codes and
buyer address. Tenders are stored with the source "EU Supply - UK"
as eusupply-uk-<tender id>, with one release holding the tender as
read.
The site publishes no rate limit, so the client sets its own: one
request at a time, with a random wait between
sources.eu_supply.request_min_gap and request_max_gap (2s to 10s).
The source has the same 7-day backfill as Find a Tender's.
Most of its tenders are also on Find a Tender, so a new one is stored
Hidden and Skipped when another source's opportunity released within
30 days has a title at least 90% alike, and its buyer or description
matches too (80% of the shorter one's significant words).
Every column's header is a button that sorts the table by it, and
clicking it again sorts the other way. A column starts with the most
useful first: titles A to Z, the latest dates and highest values, Yes
before No, hidden first, and marks in the menu's order. Statuses sort
in the filters' order rather than alphabetically, and titles by their
words and numbers, ignoring case and punctuation. Rows with no value in
the column (no date, no value, no marks) go last either way, and rows
that tie are newest release first.
The sort is remembered with the other preferences, and is newest
release first until another is chosen, as before. Sorting has moved
out of filterOpportunities, which now keeps the order it's given.
Backfilling a long window (an early --since, or a long time offline)
hit the API's rate limit, which could still be exceeded after waiting
once, and then everything fetched so far was lost.
Before each Find a Tender source's worker starts, a start point more
than 7 days ago is now backfilled in 7-day windows bounded on both
sides, oldest first, each saved before the next is fetched. A window
that fails is saved as far as it got and fetched again from its start
after the source's interval. The worker then carries on from the end
of the last window.
A 429 is now waited out up to sources.<source>.rate_limit_retries
times (default 5) rather than once; fts-once --ignore-rate-limit uses
0. FetchAll returns what it fetched before an error along with it, and
the workers save it, so a failed run no longer loses its data.
findatender's FetchAll and FetchOnce take RequestOptions, which gains
Until (updatedTo), and RateLimitRetries replaces AllowRateLimit.
The classifications are grouped by kind (CPV, then Other) and, within
CPV, nested by the CPV hierarchy: each code sits under its nearest
ancestor in the list, so one whose parent isn't in use isn't lost. The
other codes have no hierarchy, so they're listed flat. Branches start
closed; a search shows the matching codes with their ancestors, opened
when no more than 150 match.
Ticking a code selects it and every code beneath it, and ticking a
whole selected branch clears it. The checkboxes are tri-state, showing
a dash when only part of a branch is selected, and a closed branch that
is partly selected says how many codes beneath it are. The selection
above the tree shows a whole selected branch as one chip, with the
number of codes beneath it, and removing that chip clears the branch.
The filter is unchanged: a set of classification ids, so a branch is
the codes in the picker when it's ticked.
sources.skip_rules_file names a JSON file of filters, each with a
comment, an active flag, a logic mode ("or" by default, or "and") and
rules by buyer, title words or CPV codes. The fetcher applies them
before saving, so only new opportunities are marked; the marks of
stored ones are never touched. CPV rules match when the opportunity's
codes are all in the list, or any of them with exclusive false, and
by prefix with exact false.
The file is read again when its time or size changes: an invalid edit
is logged and the last good rules kept, and a deleted file means no
rules until it's back. fetcher service and serve refuse to start if it
is define but missing or invalid.
job-search skip-rules check validates a rules file, and skip-rules
apply marks the stored opportunities that match Skipped, or only lists
them with --dry-run.
Every row has a details icon under the Find a Tender link. It opens a
dialog with the opportunity's details from the list, and fetches the
opportunity with its releases, shown as tabs, newest first. Each tab
summarises the release's tender, awards and contracts, links to its
Find a Tender notice where it is one, and has the release's JSON,
pretty-printed and highlighted, in a section laid out only when it's
opened.
The JSON is highlighted by splitting it into tokens shown as text, not
HTML, as releases come from outside sources. The README's saved
preferences now include the filters.
It lists the classifications the opportunities in the days window have,
not every one stored, plus any already chosen, so a selection stays
visible and can be removed when nothing in the window has it. The other
filters don't narrow it, so choosing a status doesn't make
classifications vanish.
Every filter, the days and title included, is stored under
job_search.filters when it changes and read back when the page loads.
A stored field that isn't valid (missing, from an older version or
edited by hand) falls back to its default, keeping the rest. Clear
filters still goes back to the defaults.
GET /api/opportunities takes released_from, an RFC 3339 time, and lists
only the opportunities whose latest release is at or after it. It works
with paging and with changed_after, which keeps the same batch either
way; an invalid value is 400.
The frontend's filter defaults to 7 days, from midnight UK time, and
sends it with every load and catch-up, so a year of opportunities isn't
downloaded to show a week's. Changing the days loads the list again;
Clear filters goes back to 7.
It hides the opportunities the filters show that aren't hidden already,
after asking for confirmation with their count. Those the filters leave
out keep their marks, so clearing the filters shows them as before.
The backend has no bulk route, so each opportunity is hidden with its
own request. The rows go at once; every mark change is now saved at
most six at a time (lib/concurrency.ts), so hundreds of requests aren't
sent together. Any that fail are shown again, with one toast for them
all.
Opportunities from Find a Tender have a link icon before their title.
Clicking it fetches the opportunity with its releases (the list leaves
them out) and opens its newest release's notice,
www.find-tender.service.gov.uk/notice/<release_id>, in a new tab. The
tab is opened on the click and pointed at the notice when the request
returns, so it isn't blocked as a popup; if the request fails, or there
are no releases, it's closed and a toast says why. Opportunities from
other sources have no link for now, but keep its space so the titles
line up.
The icon is lucide-solid's, added for it at 1.52.0.
Each save that records a batch also deletes, in the same
transaction, the batches older than database.change_batch_retention
(30 days by default; 0 or less keeps them for ever), with their
records of opportunities. A client still holding a deleted batch
gets 410 Gone from ?changed_after= and reloads the whole list, as
for any unknown batch.
go generate ran ocdsgen with go run, from go.mod, but go-ocds had been
dropped from go.mod (nothing imports it, so go mod tidy removes it), which
broke go generate and so scripts/build.sh. It now runs the installed
ocdsgen from PATH, as it does swag.
scripts/install-dev-tools.sh installs the Go tools (ocdsgen v1.0.0 and swag
v2.0.0-rc6 pinned, as other versions could generate different code;
golangci-lint, goose and cobra-cli at their latest), checks for Node.js 24
or later and runs npm ci in web/. The README's dev tools section now points
to it and lists what each tool is for.
`npm run sync` in web/ copies the build output (web/dist, from npm run build)
to internal/frontend/dist, which the binary embeds. Go can't embed from
outside the package's directory (web/ is also outside the Go module), hence
the copy. Only dist/.gitkeep is committed, so a fresh clone still compiles,
and a binary built without syncing first serves no frontend.
job-search serve serves server.frontend.dir if it is set, or else the
embedded build, or warns that there is no frontend. scripts/build.sh builds
and syncs the frontend before building, running npm ci first for a release
or when web/node_modules is missing.
web/CODE_CONVENTIONS.md covers the Vite, SolidJS, Tailwind and TypeScript
frontend: tooling, files, imports, exports, naming, TypeScript, formatting,
Solid's reactivity, styling, the backend's types, API calls, errors,
security, formatting values, comments, accessibility, storage,
dependencies and tests. npm run check (strict tsc -b, ESLint and Prettier)
passes, and npm run build builds it.
ESLint (typescript-eslint with type information, eslint-plugin-solid,
simple-import-sort, eslint-comments, and rules for the naming, type import,
export type and promise conventions) and Prettier (with the Tailwind class
plugin) check what they can. Tool versions are pinned exactly. Imports
between folders use @/, which works in Vite as well as TypeScript.
The backend's types are generated from its OpenAPI description into
src/types/api.ts by npm run generate:api, which turns swag's x-nullable
into null types first; src/types/Opportunities.ts names them for the app.
The app works against the backend's API: it fetches every page of
/api/opportunities with each opportunity's marks, the classifications to
filter by from /api/classifications, sets and clears marks (hidden among
them) with the CSRF token, and shows the OCDS tender statuses. Its lists'
requests are aborted when reloaded or no longer needed. The dev server
proxies /api and /ws to job-search serve, by default at localhost:9393.
web/go.mod keeps web/ out of the Go module, as an npm package in
node_modules ships Go code.
The page stays up to date over the backend's WebSocket (src/api/events.ts,
with hand-written event types in src/types/Events.ts), reconnecting with a
growing delay. ClassificationsUpdated changes the filter's classifications
in place and OpportunityMarksUpdated sets an opportunity's marks (unless
this page is still saving its own change). OpportunitiesUpdated catches the
list up: it asks for the opportunities changed after the last change batch
it has seen (changed_after) and merges them in, reloading the whole list
only when the backend doesn't know the batch. A reconnect catches up the
same way and reloads the classifications.
internal/frontend serves a Vite build from an fs.FS: hashed files under
/assets/ are cached for a year, HTML and other files get no-cache, ETags are
computed (and cached for a build that can't change), precompressed variants
are served when the client accepts them, and a path without an extension
falls back to index.html for client-side routes. Only GET and HEAD are
allowed.
server.WithFrontend serves it for every path outside /api and /ws, behind
compression and the frontend group's hooks. job-search serve passes the
directory in server.frontend.dir, checked for an index.html at start; empty
means no frontend. Its option building moved into serverOptions, with the
access log.
Every save that stores new opportunities or new releases records them in a
change batch (migration 00008: opportunity_change_batches and
opportunity_change_batch_opportunities; the opportunities table is
unchanged), as does every change of marks. A batch is named by a random
SHA-256 hash, so it can't be guessed, and ordered by its created_at, which
is kept strictly increasing even if the clock goes back.
GET /api/opportunities pages now carry the newest batch, read before the
page, and GET /api/opportunities?changed_after=<batch> returns every
opportunity changed since that batch, unpaged, with the newest batch it
includes. Offset and limit can't be combined with it, and an unknown batch
is 410 Gone, telling the client to reload the whole list.
OpportunitiesUpdated now carries its save's batch, and a "large" flag: over
50 opportunities, new and updated are left empty and only the summary
counts them, so a big catch-up no longer sends tens of thousands of UUIDs.
SaveOpportunities now reports the classification codes a save brings into
use (AddedClassifications, in full) and takes out of use
(RemovedClassificationIDs), by comparing the codes in use before and after
the save inside its transaction. The fetcher publishes them as a
ClassificationsUpdated event, {"added":[codes],"removed":[ids]}, never null,
before the save's OpportunitiesUpdated, so clients can keep their list of
classifications without asking the API again.
GET /api/opportunities lists the stored opportunities, newest release first,
a page at a time (offset, and limit up to 100, default 50); has_more says
whether another page follows. GET /api/opportunities/{uuid} returns one with
its releases. PUT and DELETE /api/opportunities/{uuid}/marks/{mark} set and
clear one mark (hidden, skipped, interested, bid_submitted, won, lost) and
return them all; won and lost exclude each other (409). The API uses the
types in internal/types, and changing a mark is made atomic, as the store
replaces all of an opportunity's marks at once. The marks are found by
reflection: every bool field of types.OpportunityMarks, by its JSON name, so
a new mark needs no API change.
The API has one entry point, api.New, with its dependencies as options
(api.WithStore), and the server only mounts it under /api, keeping the
middleware. New resources are added inside internal/api. job-search serve
passes server.WithStore when database.file is set, opening the store before
the server; without one there are no opportunity routes.
The API is described by swag v2 annotations on the handlers. go generate
writes the OpenAPI 3.1 description (git-ignored, like the OCDS types), which
the server embeds and serves at /api/openapi.json, with Swagger UI at
/api/docs. A test checks the description and the routes match. swag is in
the README's dev tools, pinned to v2.0.0-rc6, and the build now needs it.
internal/events decouples the parts of JobSearch that cause events from
the parts that react to them. bus.go has Bus: Subscribe, and a synchronous
Publish that calls each handler in turn on the publisher's goroutine, so
handlers mustn't block (the hub doesn't: it queues per client). events.go
has the event types and their payloads, starting with OpportunitiesUpdated.
With fetcher.WithEvents, a save that stores new opportunities, or new
releases of stored ones, publishes OpportunitiesUpdated with their UUIDs and
counts. An opportunity whose row is only rewritten, as when it is fetched
again from the newest stored release, isn't counted as updated, and nothing
is published when nothing changed. store.SaveResult now reports
NewOpportunity for each opportunity saved.
job-search serve subscribes its WebSocket hub to the bus, so every client
gets {"type":"event","eventType":"OpportunitiesUpdated","payload":{"new":
[...],"updated":[...],"summary":{"new":n,"updated":n}}}. The Envelope gains
an eventType field, and Hub.PushEvent and Server.PushEvent send events.
Without --since, fetcher service and job-search serve start each source
from the newest release stored for it (the new store.LatestReleaseDate,
by Source), so a restart carries on where it left off instead of fetching
the last day again; with nothing stored, the client's default still
applies. --since overrides it for every source. The Find a Tender source's
name is now a constant, as the Source its opportunities are stored with.
The README's guide to adding a source is brought up to date with the
current worker, start and config type names.
With WithStore, the Find a Tender and mock workers save each run's
opportunities with SaveOpportunities and log what changed; a failed save
fails the run, so the checkpoint stays put and the next run retries.
Without a store nothing is persisted. The mock's opportunities are saved
with Source "FTSMock" rather than the converter's "FindATender".
fetcher service and job-search serve open the store at database.file
(cli.OpenConfiguredStore), or warn and run without one. A missing file
isn't created, and a database needing migration says to run job-search
migrate.
Fixed upsertOpportunity, which never wrote the source column, so every
saved opportunity had an empty Source.
Without server.csrf.tokens.key, each server process signs CSRF tokens with
a random key of its own, so tokens are lost on a restart and rejected by
other instances. "job-search config generate-csrf-key" stores a new random
32-byte hex key in the configuration file, without printing it. --print
only prints a key, for JOBSEARCH_SERVER_CSRF_TOKENS_KEY or another
instance. An existing key is only replaced with --force, as that
invalidates every issued token, and no key is stored while
JOBSEARCH_SERVER_CSRF_TOKENS_KEY is set, as it would override the file.
fetcher.Run(ctx, conf, since) becomes New(&conf.Sources, opts...) and
Run(ctx, since). Each worker now takes only its own source's config, and
Run starts each one through a closure that binds it. Cancelling ctx stops
the workers through the Fetcher's background context, and Run always waits
for every worker before returning their joined errors.
The findatender client no longer holds the configuration: New takes only
the API root, ReloadConfig is gone, and request tracing follows
logging.IsDebugEnabled(). The FindAOpportunity worker is now FindATender.
job-search serve runs the fetcher alongside the HTTP server. A source that
fails stops the server, and the server stopping stops the sources; with no
sources enabled the server keeps running. fetcher service and fetcher
fts-once use the new APIs.
One of the two is required. --http-upgrade upgrades an HTTP connection to
a WebSocket on /ws, as before, for job-search serve; --url and --origin go
with it. --direct connects straight to ws-test serve over plain TCP, one
JSON message per line, at --addr (default from server.host and
server.port). --ping, --message, --listen and stdin work the same in both
modes. The README's ws-test section explains the two modes.
job-search no longer has a fetch command. Its subcommands are now in
cmd/fetcher, which reads the same configuration: "fetcher service" runs
every enabled source's fetcher on its interval until stopped, and
"fetcher fts-once" (was "fetch once") fetches from Find a Tender once and
prints the releases as JSON. The new namea say what the commands do,
because service runs every source while fts-once fetches only from Find a
Tender.
The code stays in internal/cli/fetch, where NewCommands replaces the fetch
parent command. once.go is now fts_once.go and commandOnce is
commandFTSOnce. The README's usage, the config README and the find_a_tender
api_root comment now give the new command names.
The serve command runs internal/server: the API under /api (health, and
the CSRF token endpoint) and the WebSocket hub under /ws, over HTTP or TLS,
with an optional HTTP to HTTPS redirect, the PROXY protocol from trusted
sources and a graceful shutdown that closes WebSockets first. Its middleware
covers the client IP behind trusted proxies, request IDs, request logging,
panic recovery, global and API rate limits, Host and body size checks,
security response headers, compression, CSRF protection (cross-origin
checks and signed double-submit tokens) and JSON-only API bodies. Middleware
that logs takes a WithLogger option.
New server config sections: proxy, csrf, tls, headers and frontend (not
used yet), plus max_header_bytes, max_body_bytes, global and API rate limits
and HTTP read, write and idle timeouts. Every setting documents what 0 or
empty means, and internal/config/README.md is reorganised by section.
server.timeouts.read_header must be greater than 0, and a header or idle
timeout of 0 means no limit rather than the read timeout.
WebSocket upgrades are protected by the Origin check: the server's own
origin, or one of csrf.cross_origin_protection.trusted_origins, which the
hub now takes with WithTrustedOrigins.
wsserve becomes "ws serve". "ws dial" opens a WebSocket on /ws to test it:
--ping sends a ping and waits for the pong, --message sends messages and
prints the replies, --origin tests the Origin check, and with neither
--ping nor --message each line of stdin is sent until Ctrl+C.
An enabled Find a Tender or mock source with no api_root used to start
and then fail on every fetch. Its worker now returns an error naming the
missing key before it starts, which stops Run. "fetch once" checks
sources.find_a_tender.api_root the same way. TestRunMissingAPIRoot covers
both sources, and TestRunLogsSourceErrors sets an api_root so it still
tests the zero interval. The section docs and internal/config/README.md
say what an empty api_root means.
CODE_CONVENTIONS.md sets out the conventions for Go code in this
repository: naming, layout, comments, errors, logging, configuration and
tests. .golangci.json enables the linters that check the parts that can be
checked (each limited to the rules the conventions use); the rest is
applied by hand.
Applied across the codebase:
- Naming: full-word names in application code, initialisms in one case
(BuyerID, PrintJSON, PrintYAML, ocdsGetBuyerID), no names shadowing
built-ins (min/max are minGap/maxGap), mustRaw renamed rawJSON as it
returns nil rather than panicking, and config.ConfigLevelToLogLevel
renamed LevelToLogLevel.
- Layout: lines kept to 80 characters where possible, assignments taken
out of if and for statements that don't fit, wrapped arguments all on
one line or one per line, steps separated by blank lines, no else after
a return, function and struct literals wrapped.
- Comments: doc comments on every exported name (including each section's
Map, Flatten, TypeOf, ValueOf and SetValue), section banners, British
spelling.
- Errors: a created error starts with its package name, a wrapping error
adds only what was being done, sentinels in one commented var block,
errors.Is and errors.As in place of == and type assertions, and no
err := shadowing of a named result. That fixes the mock server losing
its access log's close error.
- Logging: the fetcher passes its workers an untagged logger, so
findatender's lines are tagged with their own component rather than
with fetcher's as well; cmd/mock-fts logs "stopped" with slog.
- Configuration: util.WithTimeout (moved from the websocket package)
applies a timeout of 0 or less as no limit, used for the websocket
write and ping, TCP close and tcpserver shutdown timeouts; every setting
documents what 0 or empty means, including the rate limit rule's keys
in internal/config/README.md.
- Tests: related tests merged into table-driven ones with named cases.
Separately from CODE_CONVENTIONS.md, internal/store/README.md gains a soft
SQL style convention for the queries in internal/store/queries.go, and the
queries are reformatted to follow it.
Short and single-letter names in application code become full words (tests
keep theirs). Wrapped calls, signatures and composite literals put one item
per line, and one-line function bodies are expanded. Exported names and
groups of constants get doc comments, and comments refer to the renamed
identifiers.
Log messages are lower-case event names with their details as key/value
attributes ("error" for errors), in place of formatted strings.
Loggable package take a WithLogger option as part of their "New*" call,
defaulting to slog.Default(). Each tags its lines with its `component`.
Some debug loggers print directly rather than using slog when in
terminal logging mode.
- a source's interval must be greater than 0: a source is turned off with
enabled, not with a zero interval, so JSCSourcesSource rejects an interval of
0 or less (its validate is promoted to each source's section);
- max_message_size rejects -1: JSCServerWebSocket rejects a max_message_size
of -1 (util.ByteSizeNoLimit), as a client could then exhaust the server's
memory;
- every setting documents what 0 or empty means (zero/none, no limit or a
default).
gci is configured with the sections standard, default and localmodule, and
goimports with the module path as its local prefix, so both formatters
agree.
which runs a plain TCP server for receiving websocket hub clients, with
server config, CSRF and rate limit middleware.
- internal/websocket: Hub pushing messages to WebSocket clients (ServeHTTP,
example.com/ws upgrade with optional CSRF check) and plain TCP clients (ServeTCP,
newline-delimited JSON envelopes); ping/pong keepalive, per-client message
rate limit, slow consumer handling, graceful Shutdown, debug logging of
messages sent and received
- internal/websocket/tcpserver: standalone TCP server for a hub, with accept
back-off, a per-IP connection limit (server.websocket.connection_limit) and
graceful shutdown
- internal/cli/wsserve: `wsserve` command running the TCP server, with
--listen/--host/--port overrides
- internal/middleware: keyed token bucket rate limiter, real client IP from
trusted proxies
- internal/httpx: RFC 9457 problem responses, request IDs in context
- internal/config: server section (host, port, shutdown timeout, rate limiter
idle TTL, websocket); util.ByteSize settings (e.g. "32KiB"); lists of
sections as single keys; empty lists stored as nil; isExplicitlySet for
printLoadedConfig; JobSearchConfigSource renamed to JSCSourcesSource;
TestSections checks every section's methods
- internal/util: ByteSize, parsed and formatted with go-humanize
- Fixed function name typo
- Fetcher/Run now returns a combination of errors if any workers error out. All other workers are ordered to shutdown if any one does error out
- findATender now returns a pointer instead of an instance from New
Fetching:
- Add `fetch service`, which runs a worker per enabled source until
SIGINT/SIGTERM (internal/fetcher)
- Add util.Worker: runs a task on an interval with a since-checkpoint
that only advances on success, and a shutdown timeout for in-flight
work; plus AwaitTask/AwaitTaskE for calls that ignore cancellation
- Add fts_mock and sleeper sources
- Sleeper: sleeps periodically to emulate work being done. Can be
instructed to block the shutdown signal or handle it cleanly
Mock FTS server (cmd/mock-fts, internal/mock/findATender):
- Serves GET /api/1.0/ocdsReleasePackages with FTS paging, query
validation, UK local time handling and per-client rate limiting
- Generates fictional releases from an embedded catalog, moving
procedures through planning, tender and award, and keeps them in a
JSON Lines store that survives restarts
- Add logging.AccessLog for combined/common access logs
- logging: LogToFile shadowed the package-level fileLogger, so
IsFileLogger was always false and Shutdown never closed the file
- logging: replace IsJSONHandler's unsafe reflection into slog
internals with a *slog.JSONHandler type check
- cli: fail if the log file can't be opened instead of silently
logging to the terminal; return the log shutdown error from Finish
- build.sh: -X flags used the wrong module path, so the version, build
time and commit were never stamped
- Convert OCDS releases to types.Opportunity (internal/types); FetchOnce
and FetchAll now return opportunities, built from each ocid's latest
release
- Include each item's main classification as well as its additional ones
- Return ErrUnexpectedStatus for non-200 responses and
ErrRateLimitExceeded for a repeated 429; close discarded bodies
- Stop fetchAll on a repeated next link and close each page's body once
read rather than deferring in the loop
- Default a zero Since to 24 hours ago
- Merge date repair and releaseIDs into api.go
- Filter --planning/--opportunities/--awards on each procedure's current
stage, using OCDS release tags; --opportunities previously matched a
nonexistent "opportunity" tag and returned nothing
- Reject conflicting filters before fetching (cobra flag group)
